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

The current Chu Fengmian is as if he is facing a box full of treasures, but he has no key and cannot open it.

If he didn't refine the underground spiritual milk, Chu Fengmian would never be able to swallow this rock.

"No, I don't. ”

The corners of Chu Fengmian's mouth showed a somewhat confident smile.

This refined the underground spiritual milk, but it was still difficult for him.

"Oh?"

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

He wanted to see what means Chu Fengmian could use to refine this underground spiritual milk.

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

At the center of this chamber is a huge alchemy furnace.

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

"Alchemy?"

Xing Xuan looked at Chu Fengmian's actions, and naturally understood what Chu Fengmian wanted to do.

It's just that he was extremely surprised in his heart, at such a young age as Chu Fengmian, he could actually refine the pill?

Alchemy is not an easy thing, for example, looking at the entire martial arts country, the number of alchemists is not more than a hundred.

Most of them are just alchemists who can refine some yellow-level mid-grade and low-grade alchemists.

There are only ten alchemists who can refine the yellow-level best elixir.

And what is really enough to be called a high-level alchemist, refining Xuan-level elixir, is no more than a palm.

Martial Arts Country, but with a population of hundreds of millions, there are only a hundred alchemists, this is a real one in a million, which is even rarer than those martial arts geniuses.

At such a young age as Chu Fengmian, it is not easy to practice martial arts, but now it seems that Chu Fengmian still knows how to do alchemy?

Xingxuan's thoughts, Chu Fengmian naturally didn't care, he walked to the alchemy furnace and sat down.

I saw Chu Fengmian's hands move, and a stream of spiritual power was injected into the alchemy furnace.

A flame burns out of it.

"Xuan-level mid-grade alchemy furnace, although it is not very good, but it can still be used reluctantly. ”

Chu Fengmian glanced at the alchemy furnace, and glanced at the corner of his mouth, as if he was a little disgusted.

But now that it was not what it used to be, he couldn't find any better alchemy furnace, so he could only use it first.

One of Chu Fengmian's hands had always been placed on a magic circle on the alchemy furnace.

In refining the elixir, in fact, the most important thing is to control the flames.

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

But most of the alchemists, in fact, they are not obsessed with martial arts, so it is naturally impossible to obtain the Divine Sea Realm.

Therefore, when refining the alchemy furnace later, a magic circle to control the flames would be carved on the alchemy furnace.

It is used as a fire control technique.

When refining the elixir, one hand must be kept here all the time to control the flames.

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

If the temperature of the flame is too low, it will not be able to completely melt the elixir, and it will not be able to be refined naturally.

If the temperature of the flame is too high, it will burn the elixir, causing all the elixirs to be destroyed.

Therefore, the knowledge of controlling flames is still extremely important.

Chu Fengmian sat next to him, constantly controlling the flames in it.

The flame in the alchemy furnace is sometimes large and sometimes small.

This is Chu Fengmian familiar with.

He hadn't refined an elixir for a long time, so if he wanted to refine it like this, he naturally had to be familiar with it for a while.

It wasn't until five minutes later that Chu Fengmian finally opened his eyes, and in his eyes, he was extremely confident.

"Go!"

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

This milky white rock, as soon as it enters the Dan furnace, is covered by a triple flame.

These triple flames, surrounding the milky white rocks, refine the underground spiritual milk in different directions.

"Triple Fire Control Technique?This little guy actually knows this kind of technique that only alchemy masters know?"

Xing Xuan was also taken aback when he looked at Chu Fengmian's actions in his mind.

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

For example, some high-grade elixirs, there are hundreds of kinds of materials alone, and if they are refined with a heavy flame, the materials have not been completely melted, and some of the materials have been scrapped.

At all of that time, it would be necessary to use the dual fire control technique, or even the triple fire control technique.

It's extremely difficult to do two things, or even three times.

Especially this fire control technique, you must concentrate on it, the slightest negligence, as soon as the temperature is high, it will end up in a ruined end.

If you can control the double flames, you are the best among the alchemists, and if you look at the martial arts country, you may not be able to find an alchemist who can control the double flames.

An alchemist who can control the triple flames at the same time, the entire Nine Domains, is extremely rare, which one is not an alchemy master who has been famous for a long time, and they are all over a hundred years old.

Like Chu Fengmian, who was less than twenty years old, he actually knew 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 actually be born in the Nine Domains.

But Xing Xuan would never have imagined that Chu Fengmian had experienced hundreds of years in this body that was less than twenty years old.

Under the master of the sword path, Chu Fengmian originally wanted to cultivate martial arts, but every time he returned in vain.

Lost, he has also tried others, but in this alchemy, his attainments are extremely high.

In the past, he was enough to refine the Heavenly Grade Pill, but that was also with the help of the Dan Furnace of the Sword Master at that time.

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

"Underground spiritual milk, come out for me!"

Chu Fengmian observed the situation in this alchemy furnace and looked at the milky white rock, which was already burned red.

The spiritual power in it is also becoming more and more condensed.

Chu Fengmian knew clearly that this was exactly what the underground spiritual milk was condensing.

The earth's spiritual milk, but the condensed of the world's most refined spiritual power, is definitely not something that can be burned by flames.

Therefore, what Chu Fengmian did was to condense all the underground spiritual milk in the milky white rock, and then destroy the milky white rock at once, and completely refine the underground spiritual milk.

"It's now!"

Chu Fengmian's eyes became serious, and he was sure in his heart.

Another flame suddenly appeared in it.

"The fire of the four elephants!"

These four flames, in the Dan furnace, even formed a large array, and the milky white rock in it shattered with a bang.

With the shattering of the milky white rock, a drop of milky white underground spiritual milk was also completely divided, and when Chu Fengmian opened the Dan furnace, it fell into Chu Fengmian's hands.
