Seeing that Cao Yu was so confident, Lu Liang, Lao Liu Zi and others were very much looking forward to it.

"Brother Lu, you have to ask for an alchemy furnace!"

Cao Yu turned his head and looked at them a little helplessly, did these old guys want him to refine two pills in one pill furnace!

With his strength now, he will definitely not be able to do it, and as for the future, it may not be possible! After all, who can say what will happen in the future.

"Oh yes, I'm so foolish! Come on, here you go!"

As he spoke, Lu Liang took out a quaint Dan furnace from his storage ring.

"President, this is your treasure!

Old Liu Zi and Fei Chang looked at the Dan furnace that Lu Liang took out, and they were extremely surprised, usually this old guy was not even willing to use it for alchemy, and when he used it occasionally, he would only use it to refine extremely high-grade pills, but now he was willing to take out this baby bump.

It's really an iron with hair!

"Brother Cao's Dan Dao is incomparable, I think he is the only one who is most worthy of using this Dan furnace!"

Having said that, I saw that Lu Liang's face was a little unbearable.

Cao Yu looked a little funny, this old man, he couldn't bear to slap him, so he reminded: "Brother Lu, there's no need to be like this, I'm experimenting, if it fails, won't it ruin your good Dan furnace?"

"Eh, what are you talking about! Brother Cao will definitely succeed immediately! Come, take it!"

As if he was afraid of being laughed at, Lu Liang was no longer entangled, and threw the Dan furnace to Cao Yu.

"Haha! Brother thinks so highly of me, then I have to go all out to be worthy of your baby!"

Seeing that Lu Liang was so happy, Cao Yu thought in his heart that he had to do his best so that he would not disappoint them.

"Just do your best, no pressure!"

glanced at Cao Yu indifferently, and a warm smile appeared on his face.

This appearance is far from the one in the hall outside just now, and Lu Liang really deserves to be an old fox.

At least that's what the remaining three of them in the room think.

"Then I'll start! Stay away, I'm afraid I'll hurt you!"

This time, because both hands have to input the true yuan, Cao Yu's difficulty in refining the pill will increase a lot, although he has a countermeasure in his heart, but he has not actually tested it, and no one knows if it will fail.

There was no problem in removing impurities and preheating the Dan furnace in the front, but when it came to the stage of refining medicinal materials, the problem began to come.

This process is actually equivalent to throwing the alchemy work of two people to one person at the same time to complete.

One of the most difficult is that it is necessary to separate the spiritual consciousness and control the true element separately to adjust the firepower in order to achieve the effect of refining medicinal materials.

However, this problem is naturally not difficult for Cao Yu, the soul of the book can be divided into ten thousand wisps before, although the soul power required for this alchemy is much larger, it is still not affected.

This time it is also refining the honorable level pill, that is, the Bone Pill, but both parts are the same, Cao Yu only needs to refine it according to the same steps on both sides, it should not be a big problem, it is just a matter of controlling the degree of fineness.

When Cao Yu threw all the medicinal materials into it, Lu Liang almost wanted to scold, but was stopped by Lao Liuzi!

"President, you just have to look at it! It's been refined like this before!"

Although he felt that this was so unbelievable, he knew that Lao Liu and the others were the only ones who had seen Cao Yu refining the pill with his own eyes.

So I held back the excitement in my heart and chose to continue watching.

In fact, when Cao Yu was thinking about refining two furnaces of pills at the same time, he thought about all the problems in the alchemy process.

The refining of medicinal materials lasted for half an hour, and when Lu Liang smelled all kinds of medicinal fragrances, his eyes were about to pop out, not only did he not have the tendency to explode the furnace, but the process of refining medicinal materials was surprisingly smooth.

Now he was extremely curious in his heart, how could Cao Yu be able to refine so many medicinal materials at the same time,

This refining liquid is very knowledgeable!

Each kind of medicinal material, because of the different growth environment, the characteristics of the growth are naturally different, some are cold, some are negative, varied, for the alchemist, before refining the elixir, the stone must understand all the characteristics of each medicinal material.

Because as long as the relevant properties of a medicinal material are not fully understood, the heat used in refining the liquid medicine will naturally not be able to be refined in the best state, so that the efficacy of the medicinal material will be greatly reduced, and the medicine will be scrapped directly!

As for refining the Honorable Pill, the medicinal materials that need to be used must be at least 100 kinds of each Pill.

If it was a high-level alchemist who had just been promoted, it might take a few hours just to recognize the characteristics of those medicinal herbs.

Cao Yu directly ignored it here, not that he didn't understand, but that he already knew all the medicinal materials, as soon as he saw it, all the information and characteristics about the medicinal materials would immediately appear in his mind.

Then, in the process of refining, the spiritual consciousness he separated needed to inject different amounts of True Yuan Refining according to the respective characteristics of each medicinal material.

Therefore, Cao Yu's seemingly fluttering operation, the doorway and knowledge in it can be great! Only a senior alchemist like Lu Liang, who really understands these problems and difficulties, will know.

At this moment, his admiration for Cao Yu is like a surging river, endless.

The fusion stage of medicinal materials is the second difficulty! The understanding of pharmacology is the most tested here, and the interaction of medicinal materials can refine the elixir and the elixir.

At the same time, it can also refine the most vicious poison pill in the world, both good and evil are in one thought, through the absorption in the Danta Library just now, Cao Yu's understanding of pharmacology has been further improved.

This process of fusion must take into account the effectiveness of the pill itself.

The fusion of more than 100 kinds of medicinal materials, the difference in the order of fusion, can create countless fusion schemes, and it is naturally possible to refine countless kinds of pills with different qualities.

For the sake of insurance, Cao Yu directly integrated a trace of the law of life that he felt from Ling'er into it.

The Law of Life is one of the most mysterious laws of time, and the liquid that added this trace of the Law of Life breath instantly became vibrant, and all the mysterious elements in the air were absorbed.

Following this breath, Cao Yu's mind instantly burst out like a blowout, and all the mechanisms and integration concepts of vitality clearly appeared in Cao Yu's mind.

In less than a stick of incense, the medicinal herbs are fused in a perfectly superimposed manner, and there is almost no loss of medicinal power.

By this time, the fragrance overflowing from the liquid medicine had filled the entire alchemy room, and this was the first time that Lu Liang had seen such a strong fragrance coming out of a venerable pill since he was an alchemist.

Because of the saint-grade pills, some of the medicinal materials can be easily refined, and they can waft out an extremely fragrant medicinal fragrance.

But those who can refine the supreme-grade pill into a saint-grade pill effect are really very few people who can do it.

Lu Liang stayed in the mysterious land of Zhongzhou for a while, and was fortunate enough to witness it once, but compared to the current situation, it was a difference between a bird and a bird!

The horror in his heart was beyond words, but what made Lu Liang most uncomfortable was that Cao Yu was basically injecting true yuan the whole time, and he didn't do anything!

But this did not stop the three of them from worshiping Cao Yu, and the strong medicinal fragrance was the best evidence.

The next moment, Cao Yu patted the bottom of the Dan furnace with both hands, and slapped the two Dan furnaces above his head, now that the fusion has been completed, the requirements for the true yuan in the next stage of locking spirit and Cheng Dan are no longer high, just inject a part of it into it, keep the residual heat, so that the effect of the medicine will not be lost.

Considering the characteristics of the elixir, Cao Yu needs to arrange multiple formations to enter it, anyway, the Spirit Gathering Array is a must, this thing seems to be ten thousand essential oils, and any elixir is suitable.

After all, the aura of heaven and earth is suitable for everything, and the other thing to consider is the element of giving birth to white bones.

Bones! It's actually calcium, but this thing is extremely rare in the air! But it doesn't affect Cao Yu, because he knows how to increase the increase of this element, that's right! It's the evolution of the five elements!

Although esoteric, with the Chaos Library, everything becomes SoEasy!

In order to avoid the shortage of the five elements in the air, Cao Yu directly used the Heaven Devouring Divine Skill to devour all the five elements in the entire alchemy room, and then injected them into the Dan furnace and used the Five Elements Array to evolve.

After doing all this, he will not give up! Once again, he will merge with the slightest breath of the law of life.

But after the last law of life aura was fused, the effect of the elixir was strengthened several times.

"Ahh

The first thing I couldn't help but was Fei Chang, and said with a comfortable face.

"Fat intestines, you don't miss the girl, do you!

Lao Liu Zi looked at him with some disdain on the side, as if he was mocking him for not being able to speak, and there was no need to be like this.

"Don't say it, it seems that there really is one feeling!"

The old Liu Zi who had just finished speaking had a-like expression on his face, he felt that he was going to suffer, didn't he scold the president when he said that!

Lu Liang didn't seem to hear Lao Liuzi's words, and continued to enjoy this danxiang by himself, to this extent, he felt that this trip was completely worthwhile, and looking at Cao Yu's formation, it was estimated that there was a great chance of success in refining.

It hasn't been completely successful yet, and he doesn't know if there will be variables, so he doesn't dare to assert it in his heart.

"Uhhhh It seems to have been!"

Seeing that his own president said so, Lao Liu Zi could only echo it.

Cao Yu, who has completed the lock spirit, continues to the last Cheng Dan.

The most difficult level has been passed, and the final Cheng Dan is actually not difficult, as long as you follow the steps, there is nothing wrong with this step.

After the so-called wind and rain, there will always be a rainbow!

Frostfall City surged again, and dark clouds began to converge, and this time the scale was terrifying compared to the previous two times combined.

In one day, the thunder tribulation has been slashed for no reason, and everyone knows that something big has happened.

And the focus of all this is where Danta is!

On this day, the Danta branch of Frostfall City is destined to be known to the world.
