After bidding farewell to Dongfang Bo, Jiang Yun curiously picked up the storage ring, and spiritual energy surged into it. To his surprise, a hazy space within a one meter radius appeared in front of him, containing two books.

The storage ring belongs to the category of spatial magical tools, which is almost essential for all cultivators. There are also different levels of magical tools, and the higher the level, the higher the quality. Like this ring, it cannot even be considered a single level, so the space is not large

Jiang Yun recalled the knowledge about magical tools that Dongfang Bo had told him, while taking out two books from the ring. Just as he was about to open them, a "gurgling" sound suddenly came from his stomach.

This made him smile bitterly. Although he had become a cultivator and gained spiritual energy, which could alleviate hunger, he had not eaten for two days and two nights. In addition, he had continuously opened three meridians and eliminated so many impurities from his body. Now his stomach finally protested.

Helpless, Jiang Yun could only temporarily put the book aside and then took out a jade vase, pouring out a Bi Gu Dan from inside.

Jiang Yunfei is not unfamiliar with elixirs, and in the past sixteen years, under his grandfather's guidance, he has refined countless elixirs.

However, he had never refined this kind of fasting pill that could serve as food, after all, there is no shortage of food in the wilderness, and various plants and animals can be used for consumption. Therefore, most of the pills he refined were used to treat injuries and detoxify.

Years of alchemy experience have also sparked Jiang Yun's great interest in various elixirs. However, due to the influence of the situation and emotions at the time, he did not have time to pay attention to the Dao Ti Dan and Yin Qi Dan he had swallowed before. Therefore, now holding this Bi Gu Dan, he did not immediately take it, but carefully examined it.

He wanted to see what the difference was between the elixir taken by the cultivator and the elixir he had refined in Mangshan.

Bigu Dan is only the size of a cherry, with a light yellow color and slightly granular protrusions on the surface. When placed on the nose, a faint fragrance can be smelled.

Jiang Yun sniffed and muttered to himself, "It's made from rice as the main ingredient, with the addition of ten day fruit and green willow juice. I don't know how alchemists refine it, but the fire technique is not good. Otherwise, the surface of the pill wouldn't be so rough, and naturally the pill effect wouldn't be too good

Although Jiang Yun spoke lightly, if his words were heard by other cultivators, especially pharmacists, they would definitely be extremely shocked.

You should know that besides the materials required for alchemy, the most important thing is to have a prescription, which is the specific material ratio and other methods needed to refine a certain elixir.

For pharmacists, a prescription is definitely a precious treasure, after all, every prescription is summarized after countless failures and cannot be easily displayed to others.

However, Jiang Yun relied solely on the scent of Bi Gu Dan to determine the materials contained within it. Although he did not infer the specific formula, it is still extremely rare.

Even Jiang Yun is confident that if he has enough materials and is given a few opportunities to experiment, he should be able to refine the Bi Gu Pill, and the pill effect will definitely be much better than the one in his hand!

However, it is currently impossible for Jiang Yun to refine the Bi Gu Dan, so after studying it for a while, he put the Bi Gu Dan into his mouth.

However, a sudden change occurred!

I saw a faint light suddenly shining on the black triangular stone hanging on his chest, and then with a 'pop', the Bi Gu Dan that was about to be sent into his mouth exploded.

This familiar scene naturally reminded Jiang Yun of the previously exploded questioning mirror, and at this moment, he finally confirmed that he was not blinded at that time.

Even this time, he saw more clearly that when the Bi Gu Dan exploded, there was a wisp of sesame sized light inside, which was suddenly sucked into the black stone.

With the disappearance of the faint light, the black stone instantly regained its calmness, and everything seemed to have never happened, except for some powder of the Bi Gu Dan remaining between Jiang Yun's fingers.

What's going on? "Jiang Yun stood there, confused. The only thing he could be sure of was what the black stone had sucked away from the Bi Gu Dan.

The black stone was the only thing that Jiang Yun took away from Jiang Village, and it was also the "treasure" that Jiang Yuerou gave him before leaving and repeatedly reminded him of.

To be honest, Jiang Yun never regarded it as a treasure, thinking it was just Jiang Yuerou's childhood words. However, it was given by Jiang Yuerou and could be considered a connection between him and Jiang Village. That's why he carefully hung it around his neck. Whenever he saw the stone, he felt as if he was still in Jiang Village.

But now it seems that this stone is truly a treasure!

Senior Brother once said that there are indeed many rare treasures between heaven and earth. Some are artificially refined, while others are naturally formed. However, I don't know what kind of treasure this stone is and what its function is

Jiang Yun's first thought was naturally to inquire with Dongfang Bo, but in the end, he decided to conduct his own research first.

After all, if it's really a treasure, as Dongfang Bo said, the fewer people who know, the better.

After pondering for a while, Jiang Yun poured out a Bi Gu Dan from the bottle again, just like before, and slowly placed it in front of him. However, this time, the black stone showed no reaction at all.

No response? Did you do something wrong

After thinking for a moment, Jiang Yunqiancui repeated all the actions he had taken when he took out the first Bi Gu Dan, even the time was accurate, but the stone still did not react.

"Is there any difference between the two Bigu Pills?" Yuan Yun shook his head thoughtfully and looked carefully at the Bigu Pills in his hand

Next, Jiang Yun simply poured out all the remaining pills from the bottle and began experimenting one by one, while the black stone remained motionless, completely lifeless.

What's going on? Why is it that only the Bi Gu Dan just now and the previous questioning mirror will explode when approaching this stone

Ask, Dao, Mirror

Repeating these three words, Jiang Yun's mind suddenly flashed with inspiration. He remembered what Xiao Yishu had said, asking if there was a Taoist meaning in the mirror, so that he could determine whether the Taoist spirit could be condensed in the future.

Dao Yi! "Jiang Yun's eyes lit up." When the Bi Gu Dan and the Asking Mirror exploded, what did the stone absorb from inside? Could it be Dao Yi

Ke Dao Yi, what is it again

At the next moment, Jiang Yun stood up and put everything away. After swallowing another grain pill, he immediately left his small courtyard and walked towards Dongfang Bo's residence.

Dao Yi

Upon hearing Jiang Yun's question, Dongfang Bo's eyes lit up again and he excitedly rubbed his hands, saying, "Brother Jiang, if everyone could be as eager to learn and good at discovering problems as you are, that would be great. Come on, sit down quickly, and I will explain to you in detail what Dao Yi is

Although Jiang Yun's scalp felt a bit numb, he had to obediently sit down to figure out what Dao meant.

Dao Yi, in simple terms, is the meaning of Dao, which is actually a vague and elusive existence that cannot be seen or touched

But if we go into more detail, the meaning of Dao is quite mysterious and complex! There are countless paths, and all things hide Dao. Therefore, this meaning is naturally all encompassing, such as the meaning of Sword Dao in Kendo and the meaning of Qi Dao in Qi Dao

The Dao's meaning is generally randomly hidden in all things, but relatively speaking, the probability of containing the Dao's meaning is higher in items related to cultivation. For example, when you measured the Dao's spirit before, the asking mirror contained a certain Dao's meaning, which can perceive the possibility of you condensing the Dao's spirit in the future
