As for the two spiritual tools that prevent perception from penetrating, Wang Lin now understands from the study manual that they are an additional protective measure for biological spiritual tools. High level biological spiritual tools can bind souls, while low-level spiritual tools often have restrictions similar to the need to input specific elemental powers.

This kind of restriction is added later, obviously these two spiritual tools are like this. Wang Lin sneered, he was not in a hurry. According to his understanding, there are many disadvantages to this restriction measure added later, the most prominent of which is that it does not last long.

Just now he observed that the light curtain was much weaker than before, and he believed that it would disappear soon.

After organizing all the spiritual tools, Wang Lin sat on the ground and flashed the training he needed for the future in his mind one by one.

Encountering a bottleneck in speed requires practicing physical coordination skills to break through.

In terms of elemental power, in order to obtain hidden spirits, the ninth image of the Internal Ascension Technique needs to be further cultivated. Also, find a place of extreme yin to practice the Yellow Spring Ascension Technique. In addition, the work of changing the spiral shape of the internal elemental force also needs to continue.

In terms of perception, Wang Lin did not have the techniques he was equipped with, and he wanted to practice, but he had more than enough energy.

Thinking about these practices, Wang Lin sighed. He didn't know how long it would take to complete all of them, but in order to survive better, he had to improve his strength as soon as possible.

After all, without this unique geographical environment after leaving the wilderness plain, Wang Lin knew that with his ability, his life could be threatened at any time.

Let's talk about Tuofeng. If he were in a normal state outside, Wang Lin would have no other choice but to escape, unless he used a biological artifact.

It's still too weak. Once we find the place of extreme darkness, we won't go out anymore. We must improve our strength before the expiration of our agreement with Han Hao, "Wang Lin secretly made up his mind.

He remembered that it had been a long time since he had changed the spiral shape of the elemental power inside his body. Now that he had left Tianshui City and had killed all the pursuers one by one, he finally breathed a sigh of relief. He immediately closed his eyes and immersed himself in the work of changing the elemental power,

Changing the elemental force into a spiral shape takes a long time and is extremely tedious, and the effect cannot be seen until it is completely completed.

But in order to operate his elemental power more quickly, Wang Lin endured the boredom that ordinary people could not persist in and calmly practiced.

Three days later in the morning, Wang Lin slowly opened his eyes. He first looked around and confirmed that there was no danger, then patted the dust on his body and stood up.

The transformation of Yuanli slowed down as it progressed, and it only took three days to increase from the original 15% to 23%, "he muttered to himself, taking out some food from the storage card to fill his stomach and then putting away the animal bones.

Wang Lin took a deep breath and prepared to continue moving forward. He knew that he had to stay on this wild plain for at least a few months to ensure that everything would go smoothly after leaving.

Wang Lin plans to collect more materials in the coming months for the purpose of making spiritual artifacts in the future.

Walking in the jungle, Wang Lin collected plant materials one by one, gradually increasing the amount of materials in his storage cards.

On the afternoon of the sixth day, he had just picked up a handful of electric grass from under a towering tree, when suddenly a familiar roar came from not far away.

Perceiving the appearance of an iron backed bear, the inner king Lin immediately sensed a gust of fishy wind.

Wang Lin quickly retreated without blinking, and a few flashes brought the distance to over 100 meters. He just scanned his peripheral vision and found that the Ironback Bear was the one he had teased several days ago.

I didn't expect this animal to hold such a grudge, and to catch up all the way smelling the scent. "Wang Lin touched his nose, walked quickly, and jumped between the giant trees with the help of force.

The iron backed bear behind roared and knocked down big trees in a straight line, charging sideways.

Wang Lin's speed was extremely fast, and it was obvious that the Iron backed Bear couldn't catch up. The distance was gradually increasing. At this moment, the Iron backed Bear suddenly let out a scream, followed by a tremor on the ground. The sound of the Iron backed Bear struggling and roaring in fear came from behind.

Wang Lin stopped in his footsteps, pondered for a moment, and then quietly walked back. After walking about 150 meters, he saw the Ironback Bear wrapped in a purple red branch and leaf, which was extremely large and tightly tied to the Ironback Bear like a python.

No matter how hard the Ironback Bear struggled, it was of no help. Wang Lin looked at the purple red branches and leaves, and found many fine patterns on them. He was stunned when he thought about it, it was clearly the branches and leaves of the reticulated flower recorded in the study manual.

This reticulated flower is very special. Its body is buried underground, and usually only a few branches and leaves are exposed to hunt outside.

Once surrounded by it, it will immediately entangle, and the more fiercely the prey struggles, the tighter the entanglement becomes.

The Ironback Bear let out a mournful cry, and suddenly saw spikes emerging from the branches and leaves that wrapped around its body. These spikes immediately penetrated into the Ironback Bear's body, piercing through its fat layer.

Visible to the naked eye, the massive body of the Iron backed Bear gradually withered, transforming into a skin and bones in less than ten seconds.

As soon as the branches and leaves loosened, they slowly retreated to the ground as if they were full.

Looking at the Iron backed Bear again, its eyes were dim, and a golden liquid was spitting out from the corners of its mouth. Obviously, its bile had already broken. It slowly twisted its head and stared blankly at Wang Lin in the distance, struggling to get up and slowly crawling in the opposite direction.

Wang Lin sighed. The iron backed bear was dead. His whole body was almost sucked clean by the reticulated flower. Now it's time to die, I'm afraid he will die completely in a few minutes.

The most precious material of the Iron backed Bear's entire body, its gallbladder, had already shattered. Wang Lin shook his head and turned to leave, deepening his inner fear of this barbaric plain.

After about an hour, Wang Lin cautiously avoided the habitat of some wild beasts and was walking in the jungle when suddenly a roar came from afar again.

Wang Lin was about to accelerate his departure when his footsteps suddenly stopped. His face showed a look of surprise and suspicion, and he listened carefully.

Roaring sounds came one after another, mixed with a sharp hiss.

Wang Lin's face suddenly changed, and the roar was extremely familiar, as if it was the Iron backed Bear that should have died an hour ago.

According to the description in the study manual, the iron backed bear is a solitary beast, and the chance of encountering two iron armed bears in the same location is very small. This beast has a natural intuition and will try to maintain a certain distance from each other.

After a moment of contemplation, Wang Lin immediately turned around and returned. The one hour journey through the jungle was not far, about one kilometer, after all, there was a crisis step by step here, and Wang Lin had not accelerated his speed before.

This time he walked back, Wang Lin's speed was extremely fast. As he approached, the roar grew louder and the hissing became weaker.

About twenty minutes later, Wang Lin arrived at the location where the roar was coming. He looked closely and was immediately stunned.

I saw a bear with an iron back lying on the ground, covered in scars all over its body, especially on its right leg where bones were visible. It tightly bit a struggling ball shaped object in its mouth, and the green liquid slowly dripped down as it struggled. Several long branches grew on the ball shaped object, and at this moment, these branches were also torn and bitten into several sections, with liquid flowing out from the position connecting the roots.

On the ground, there is also a deep pit with traces of soil excavation around it. At this moment, the spherical object hissed again, trembled a few times, and then remained motionless.

Wang Lin took a deep breath. The spherical object was the body of the reticulated flower, and the iron backed bear looked extremely familiar, clearly the one that was destined to die before. But now, there was no trace of its previous skin and bone weakness, and its body had miraculously recovered.

Wang Lin was startled and immediately opened the animal bones, hiding his figure.

After a long time, the iron armed bear slowly loosened its grip and roared a few times, biting at the branches and leaves on the ground again until it completely tore them apart. Only then did it stop.

It was panting heavily, licking its injured right leg while cautiously looking around. After resting for a while, it swayed and stood up, limping wearily to the side.

Wang Lin remained calm and followed quietly, feeling a strong curiosity about how this iron backed bear could recover in a very short period of time.

The iron armed bear was very careful along the way, stopping and observing around from time to time. Wang Lin followed along and found that there were fewer and fewer trees. In the end, almost no trees were visible, and the ground was covered in long weeds.

Suddenly, Wang Lin stopped in his tracks and stared blankly not far away, his heart so shocked that he couldn't speak.

In front of him was a huge city, with most of the buildings collapsing and countless coiling plants scattered throughout the city.

The city is overgrown with weeds, and the feces of wild animals are scattered everywhere. Small animals run around the city, occasionally emitting a neighing sound.

The wide road on the ground cracked open like scars, devouring life at any moment like opening a bloody mouth, revealing its ferocious face.

The thick ruins of the building stood on the ground, presenting a scene of doomsday ruins like ruins. The monotonous gray and the green of plants intertwined, revealing a sense of despair that was shocking.

After the Ironback Bear arrived here, it visibly relaxed and lazily walked to a grassy area, crawling down.

Wang Lin took a deep breath and looked at the ruins, feeling deeply moved in his heart.

At this moment, a bright light suddenly flashed on a building in the city, followed by a white beam of light that instantly shot onto the Ironback Bear. The Ironback Bear let out a joyful scream, and its right leg immediately healed at an extremely fast speed. The whole process took about a few seconds, and the Ironback Bear recovered as before.

It shook its body with joy, walked out of the beam of light, and its figure gradually disappeared into the distance.

At this moment, the beam of light was still continuously condensing, and Wang Lin's mind was greatly shaken, unable to speak as he looked at the beam of light.

Why did Iron Bear recover in a short period of time? Wang Lin understood the reason!

Just as Wang Lin was pondering, the beam of light turned into silver dots and dissipated. Wang Lin is not in a hurry, he slowly opens the animal bone and continues to wait.

According to his speculation, the time interval between the two healing sessions of the Iron backed Bear is not large, which indicates that there are frequent occurrences of light beams in this area.

As expected, an hour later, the beam of light reappeared.

After repeating this process several times, Wang Lin looked around for a day and finally saw some clues.

According to Wang Lin's judgment, the appearance of this pillar of light must be related to sunlight. Obviously, although the city has become a ruin, there are still some items similar to spiritual weapons that have not lost their function and have shown a magical scene after absorbing sunlight.

And knowing that there are many beasts here that can be healed by the beam of light, Wang Lin saw no less than twenty injured beasts come here on this day.

As the sky gradually darkened, Wang Lin calculated the moment when the last beam of light appeared. Without hesitation, he immediately stepped forward and reached into the beam of light, and a warm airflow immediately filled his hands.

Wang Lin stopped his hand and immediately used a dagger to cut open a wound when he found nothing abnormal. He reached out his hand again towards the beam of light.

Within the beam of light, the wound heals rapidly, taking only one or two seconds for the wound to disappear.

Wang Lin pondered for a moment, then quickly shuttled through the ruins without hesitation, and soon arrived at the building emitting a beam of light.

This is a grand cylindrical giant stone building. From the outside, it can be seen that it has broken off from the middle part. Although it has collapsed halfway, its former glory can still be seen. Two huge war god statues stand beside them, pressing against a tower shaped building about thirty meters long.

Wang Lin looked at the wreckage of the building and couldn't help but imagine a scene in his mind. A towering tower shaped building, in a sudden disaster, broke in the middle and the tip of the tower fell onto the statues standing on both sides.

That light spot emanated from a stone bead with a diameter of about two meters at the tip of the tower.

Looking at the stone bead, Wang Lin hesitated. It was too big to take away, and he didn't fully analyze its healing principles. If he forcibly removed it, he didn't know if it would lose its effectiveness.

After careful consideration, Wang Lin did not act rashly, but wandered and observed within the ruins of this city.

Gradually, Wang Lin's expression became strange. He checked multiple places and found an abnormality.

He saw some porcelain on the ground that remained relatively intact in many rooms of buildings, some of which even had some black substances remaining inside.

At this moment, the sky was getting darker and Wang Lin dared not linger here late at night, so he quickly rushed towards the jungle. At the moment when darkness had completely descended, Wang Lin walked out of the city and stood outside, staring at the ruins with flashing eyes.

Wang Lin suddenly had a bold guess in his mind. On a sunny afternoon, many people were sitting at the dining table, enjoying the abundant food. Suddenly, disaster struck, and without their noticing, the entire city became silent.

At this moment, a faint cold breath gradually emanated from the ruins, which grew heavier and eventually almost solidified into substance.

Judging from the size of this city, with a population of no less than ten million and tens of millions of deaths, it should be the best yellow extreme yin place among the four realms of heaven, earth, darkness, and yellow

Wang Lin immediately took out the scale used to test the extremely negative area from the storage card.

Wang Lin had carefully examined this scale gauge before, and it was also mentioned in the Huangquan Shengqiao Jue that the scale gauge can emit four types of light: purple, blue, silver, and red, corresponding to the four extreme yin areas of heaven, earth, black, yellow, and black.

In addition, the quality is also marked from bottom to top on the outside of the scale, divided into four small characters: ordinary, excellent, extremely negative, and absolute negative.

There are ten scales between each quality, divided into ten grades.

Generally speaking, reaching level three or above can be used to cultivate the Yellow Spring Ascension Technique, while reaching level eight or above can accelerate the cultivation speed.

After the scale appeared, it immediately emitted an extremely strong red light, which became brighter and brighter. A red line quickly rose from the bottom of the scale, climbed to the position of a regular fifth grade, and then stopped.

Wang Lin touched his chin, his gaze flickered, he chuckled lightly, and walked towards the city with a dial gauge.

The chilly aura around him grew stronger as Wang Lin walked in, and in the end, he even had a feeling of strolling in the water. This aura was too strong, and he felt suffocated just a few hundred meters away.

At this moment, the red light of the scale also became brighter and brighter as Wang Lin walked, and the red line quickly climbed to the eighth grade.

Wang Lin didn't stop and continued to move forward, walking a few hundred meters until he arrived at the building where the stone bead was located. He couldn't move any further, and the Yin cold energy seeped into his body, causing all the meridians and blood vessels to start stabbing.

At this point, the red line on the scale indicates that it has surpassed the normal level and reached the highest quality.

According to Wang Lin's search for the city during the day, he knew that the city was extremely large, and his current location was probably less than one ten thousandth.

And as one goes deeper, the Yin cold qi becomes stronger.

This is definitely the best place for cultivation! "Wang Lin slowly stepped back and stopped 200 meters inside the city. According to the scale, this was a regular fifth grade.

This location is also the most suitable place for Wang Lin's body after analysis.

I've made up my mind, let's practice the Yellow Spring Ascension Technique here! "Without hesitation, Wang Lin took out his animal bone and opened it, immediately sitting cross legged on the ground. Instead of practicing immediately, he began to think in his mind.

The opening time of animal bones is limited, and we cannot waste all of it on protecting our cultivation from disturbance. Moreover, those few hundred hours can easily be consumed unconsciously by ourselves.

So the most important thing now is to find a place to live here, and also to do some preventive measures, after all, this place is located in a wild plain, which is really unsafe.

In addition to these, there are many food and water storage cards in his card. After all, he has obtained so many other people's cards. Although there are not many treasures, there are quite a few daily necessities like these.

After making the decision, Wang Lin wanted to practice the Yellow Spring Ascension Technique now, but the surroundings were pitch black. Even if he took out the technique, he couldn't see the handwriting clearly. If he used lighting objects, it would be too dangerous in this darkness. Therefore, he no longer considered it and continued to complete the work of transforming his internal elemental power into a spiral shape, quietly waiting for dawn.

When he opened his eyes again, the sky gradually brightened, and the cold aura around him quickly dissipated. At the moment when the sun rose, the cold aura disappeared completely.

Wang Lin picked up the animal bones, moved his body, and immediately searched for a place to live nearby.

The ultimate goal is to locate a collapsed building 30 meters away from this location. Wang Lin sorted it out and piled up all the gravel, clearing out an area of about ten square meters.

This location provides shelter from wind and rain. Apart from the scenery outside, it also meets Wang Lin's requirements. He took out some plant-based materials from the storage card and carefully made some powerful traps around the house, which gave him some peace of mind.

After finishing everything, Wang Lin sat quietly cross legged in the room and opened the B-level technique - the Yellow Spring Ascension Technique.

This Yellow Spring Ascension Technique is divided into nine layers, and the purpose of each layer is to break through the acupoints inside the body.

According to the description of the martial arts, there are three major acupoints in the human body, and each opening of one acupoint can trigger a huge body potential. This potential can be fully activated into elemental power using the secret technique of the Yellow Spring Ascension Technique.

Once all three major acupoints are opened, one has the qualification to enter the tenth level field.

However, the success rate of this technique for flushing the body is extremely low. If you want to improve your grasp of flushing the body, it is closely related to the quality of the Extreme Yin Land.

As the day passed, Wang Lin closed his technique, closed his eyes, digested in his mind, and continued until night fell again. At the moment when the Yin cold energy rose, he suddenly opened his eyes, spread his hands between his knees, and began breathing in a way that was one long and three short as required.

The so-called 'one long' refers to a long inhalation time, while 'three short' refers to an exhalation time that is only one-third of the inhalation time.

Using this unconventional breathing method, absorb the Yin and Cold Qi from around as quickly as possible into the body.

At the beginning, Wang Lin was very uncomfortable because the Yin cold qi was immediately absorbed into his body and dispersed into his internal organs. The cold emanating from inside out made his body tremble uncontrollably.

As more and more Yin cold breath was inhaled, Wang Lin's hands and feet became cold, and the blood flow in his body gradually became viscous, eventually even slowing down his heartbeat.

His eyebrows, hair, and sweat all over his body slowly turned a frosty color, and a cold aura penetrated through his body, perfectly blending with the surroundings.

Time flew by quickly, and as the sun rose, the coldness dissipated. Wang Lin's eyelids trembled, and he opened his eyes. He exhaled a deep breath of white air, and after a night of breathing, a small air mass appeared faintly in his abdomen. This air mass silently and slowly rotated, and a trace of coldness gradually dissipated.

The elemental forces within the body have no repulsion towards this air mass, and there is no interaction between them that are unrelated to each other.

Touching his lower abdomen, Wang Lin murmured to himself, "The Yellow Spring rises to my senses, I finally know why I have to call myself that name

The Yellow Spring refers to the state of the body that must be changed to a near death state when practicing this skill, in order to be more suitable for absorbing the Yin Cold Qi in this state of about to enter the Yellow Spring.

However, if you make a slight mistake during this period, it is very likely that you will actually get into the underworld.

Wang Lin didn't know that the Yellow Spring Ascension Technique was actually not practiced by many people in the Phoenix Clan. The young lady of the Phoenix Clan was also too scared to practice again after practicing a few times and placed it deeply in the storage card.

After all, according to some of the ancestors of the Phoenix tribe who left behind, this technique of ascending from the Yellow Spring is called the Mysterious Technique.

Wang Lin pondered for a moment. Although the practice of the Yellow Spring Ascension Technique was extremely evil, it should not be false. There were no other techniques available now, so he could only cultivate it.

Suddenly, Wang Lin's face darkened.

Counting the time, it's time! "Wang Lin's tone was cold, with a hint of killing intent flashing in his eyes!
