This underground spiritual milk has now completely integrated into the rocks.

Now Chu Fengmian feels like facing a box full of treasures, but without a key, unable to open it.

If the underground spiritual milk is not extracted, Chu Fengmian cannot swallow all this rock.

"No need."

Chu Fengmian's lips showed a confident smile.

This will extract the underground spiritual milk, but it won't be difficult for him.

"Oh?"

Xing Xuan was slightly surprised, and Chu Fengmian answered. However, he did not continue to speak, but quietly observed Chu Fengmian.

He actually wanted to see how Chu Fengmian could extract this underground spiritual milk.

Chu Fengmian picked up the milky white rock and walked towards the center of the secret room.

At the center of this secret room is a huge alchemy furnace.

Looking at the traces around, this should be the place used by Xuan Jingtai for alchemy.

"Alchemy?"

As Xing Xuan watched Chu Fengmian's actions, he naturally understood what Chu Fengmian wanted to do.

But he was extremely surprised that at such a young age as Chu Fengmian, he could still refine pills?

Alchemy is not an easy task, as looking at the entire Wusheng Kingdom, there are no more than a hundred alchemists.

Most of them are alchemists who are only capable of refining some yellow grade intermediate and lower grade.

There are only ten alchemists who can refine top-quality yellow level pills.

And truly capable of being called a senior alchemist, there are no more than one palm that can refine mysterious level pills.

The Wusheng Kingdom has a population of hundreds of millions, but only a hundred alchemists. This is a true one in a million, even rarer than those martial arts geniuses.

At such a young age, it was not easy for Chu Fengmian to cultivate martial arts, but now it seems that Chu Fengmian still knows how to refine pills?

Chu Fengmian naturally ignored Xing Xuan's thoughts and sat down next to the alchemy furnace.

I saw Chu Fengmian move his hands and inject a spiritual power into the alchemy furnace.

A flame ignites from within.

"The Xuan level intermediate alchemy furnace, although not very good, can still be barely used."

Chu Fengmian glanced at the alchemy furnace and glanced at the corner of his mouth, seeming somewhat disgusted.

But now it's not the same as before, and he can't find any better alchemy furnace, so he can only use it for now.

Chu Fengmian's hand has always been placed on a magic formation on the alchemy furnace.

The most necessary step in refining pills is actually to control the flames.

I just want to use the technique of controlling fire, but only martial artists above the Divine Sea realm can control it.

But most alchemists, in fact, are not obsessed with martial arts and naturally cannot obtain the Divine Sea realm.

Therefore, in the later refining of alchemy furnaces, a magic array that controls flames was carved on the alchemy furnace.

Used as a fire control technique.

When refining pills, one hand must always be placed here in order to control the flames.

Flame is the key to refining pills, and controlling the temperature of the flame is the most important point for every alchemist.

If the flame temperature is too low, it is impossible to completely melt the elixir and cannot be naturally refined.

If the flame temperature is too high, it will burn the pill, causing it to be completely destroyed.

So the knowledge of controlling flames is still extremely important.

Chu Fengmian sat beside him, constantly controlling the flames with his hands.

The flames in the alchemy furnace are sometimes large and sometimes small.

This is Chu Fengmian being familiar with.

He has not refined pills for a long time, so if he wants to refine them, he naturally needs to become familiar with them for a while.

Until five minutes later, Chu Fengmian finally opened his eyes, his eyes filled with immense confidence.

"Go!"

Chu Fengmian drank lightly and threw the milky white rock completely into the alchemy furnace.

This milky white rock is immediately covered by triple flames as soon as it enters the alchemy furnace.

These triple flames surround the milky white rocks, refining the underground spiritual milk in different directions.

"Triple Fire Control Technique? This little guy actually knows this skill that only alchemists can understand?"

Xing Xuan was also surprised to see Chu Fengmian's actions in his mind.

The most important criterion for evaluating an alchemist is to control the flames.

Like some high-grade pills, there are hundreds of different materials alone. If refined with a single flame, the materials have not been completely melted, and some of them have already been discarded.

At that time, it was necessary to use double or even triple fire control techniques.

One mind, two uses, or even one mind, three uses, is an extremely difficult task.

Especially in this fire control technique, one must be fully focused. Any slight negligence can lead to a high temperature and result in the destruction of the pill.

Being able to control dual flames is one of the best alchemists, and even in the realm of martial arts, one may not be able to find an alchemist who can control dual flames.

A alchemist who can simultaneously control three flames is extremely rare in the entire Nine Realms. No one is not a well-known alchemist for a long time, and they are all over a hundred years old.

Someone like Chu Fengmian, who is not yet twenty years old, actually knows the triple fire control technique.

Xing Xuan even thought that the memories he had obtained before were all fake. When did such a terrifying demon emerge in the Nine Realms.

But Xing Xuan never imagined that Chu Fengmian, who was less than twenty years old, had gone through hundreds of years.

Under the master of swordsmanship, Chu Fengmian originally wanted to cultivate martial arts skills, but every time he returned without success.

Lost, he has also tried other things before, but his expertise in alchemy is extremely high.

He used to be capable of refining heavenly grade elixirs, but that was also achieved with the help of the alchemy of the master of swordsmanship at that time.

However, even now he is only condensing this underground spiritual milk from the rocks, which is not a problem for Chu Fengmian.

"Underground spirit milk, come out!"

Chu Fengmian observed the condition in the alchemy furnace and looked at the milky white rock, which had already been burned red.

The spiritual power within it is also increasingly condensed.

Chu Fengmian was clear that this was exactly what the underground spiritual milk looked like.

The underground spiritual milk, however, is condensed from the most refined spiritual power in the world and cannot be destroyed by flames.

So what Chu Fengmian did was to condense all the underground spiritual milk in that milky white rock, and then destroy that milky white rock all at once, extracting the complete underground spiritual milk.

"Right now!"

Chu Fengmian's eyes became serious, and her heart was certain.

Another flame suddenly appeared in it.

"The Fire of the Four Symbols!"

These four flames even formed a large formation in the alchemy furnace, and the milky white rock shattered with a loud bang.

As the milky white rock shattered, a drop of milky white underground spiritual milk was also completely separated. Chu Fengmian opened the elixir and it fell into his hands.
