Having said that, it took two years just to absorb the dozens of fires needed to refine the Essence Pill.

Yang Chen had always had a divine consciousness crisis before, so there was no fire in the air, and Yang Chen did not absorb it. Based on his mortal experience, the absorption of a certain kind of fire could easily cause the cultivation of divine consciousness to improve, and he couldn't help but guard against it.

Now that the crisis of divine consciousness has been lifted, he no longer has scruples, and with the needs of alchemy, Yang Chen naturally absorbs the fire first.

Fortunately, the number of fires needed for the Essence Pill is only a large number, but the grade requirements are not very high, and the highest is only the third grade of the Spirit Realm, which is also the reason why low-grade alchemists can also challenge the Essence Pill. The three-grade spirit realm fire is not difficult for Yang Chen.

The process is still the same, first absorb into the Yunling Furnace, and then let Yang Chen absorb it into the Yin and Yang Burning Sky Fire little by little.

At the beginning, Yang Chen did not want to integrate into the Yin and Yang Burning Sky Fire, but when he was studying the Danfang, he found that the alchemist's familiarity with the control of the fire was also closely related to the success rate of alchemy, and Yang Chen naturally wanted to do his best in order to pursue the limit. And to be familiar with the fire, there is no better way for Yang Chen to be familiar with it than to merge into the Yin and Yang Burning Sky Fire.

During this time, it was considered Yang Chen's preliminary preparations, so there was no complete retreat, and when absorbing the fire, it did not prevent Yang Chen from exchanging some things with the Sect Master. Fortunately, there wasn't much to be done in the affairs of the Pure Yang Palace that Yang Chen needed to interfere in, relatively speaking, Yang Chen only paid a little attention to it and didn't care much.

Often surnamed in the sect, Yang Chen looked like an idler. However, almost all of the people who appeared here were monks, and everyone understood that this should be a process of Yang Chen's mind cultivation before he really started refining.

There are many ways to bring peace to the heart, many people like to burn incense and bathe, others play the piano and write, and so on. Yang Chen's method was a little different, but it was just to maintain the activities of an ordinary person, which was really not surprising.

However, since Yang Chen announced that he was going to retreat for alchemy, even if outsiders saw Yang Chen from afar, they would not appear in front of him and disturb him. It's a form of courtesy, but also a form of respect. The masters of the big sects may be disdainful, but those who have just ascended dare not bother, everyone is waiting to see what surprise Yang Chen can finally give everyone.

Finally, after Yang Chen absorbed the tinder and became familiar with the tinder, his mood was finally adjusted to the best. After telling the master of the Sect Palace, Yang Chen officially closed the Dragon Palace and began a retreat life of isolation from outsiders.

More than 900 kinds of medicinal materials Yang Chen had already dealt with them separately and put them in a convenient position. Of course, Yang Chen only dealt with it preliminarily, and did not go into depth. Everything must be perfected at the time of refining.

The refining process had been simulated many times in Yang Chen's mind, but Yang Chen had never practiced it once. There are some things that you have to think about completely from beginning to end before you can start it, especially for a pill as complex as the Essence Pill.

In his previous life, Yang Chen had never been exposed to this level of goods, and Yang Chen had never expected that he would be able to succeed at one time. You must know that even if you add the previous life, the highest level of alchemist that Yang Chen has reached is only six grades, and that is still when he was in Da Luo Jin Immortal, and now his cultivation is limited, and it is impossible to succeed in one surname.

The fact was as Yang Chen expected, when he added the three hundred and forty-one medicinal materials, he didn't grasp the heat well, and the medicinal materials in the entire Dan furnace instantly turned into a mass of charred black medicinal residue.

Failure is failure, but Yang Chen is not discouraged. Looking at the world, which alchemist dares to say that he succeeded in refining the Essence Pill for the first time? Even if he is Taishang Laojun, it is impossible to succeed in alchemy every time, and he also goes to the peak step by step from failure.

It has been said that failure is the best teacher, and it seems to be true. The second time Yang Chen failed when he added the four hundred and seventy-seventh kinds of medicinal herbs, and there was another black cloud of medicinal residue.

The conflict between the medicinal materials was the most difficult to reconcile, and Yang Chen's ability to persist until more than four hundred medicinal materials made a mistake in the first two refining was already a remarkable achievement. This is also due to the efficacy of the massive medicinal residues in the medicine gourd.

The third time, on the contrary, regressed, and by the time the early 400s were already in their early 400s, they had already failed. After three failures in a row, Yang Chen stopped his hand and began to ponder carefully.

After all, the things recorded in the Dan Fang were not detailed in how to refine each step, and Yang Chen could only deduce little by little according to the pharmacology he knew. The three failures made Yang Chen realize that the problem was not in the back, but in the front.

After Yang Chen's step-by-step combined with practical reasoning in his mind, he quickly found the reason. When a certain main drug is handled, it seems that the technique is a little lacking, and the later medicinal materials are added one by one, and when the accumulation is almost the same, the efficacy will conflict, which will lead to failure.

No matter which sect's Dan recipe will not record such a small problem, but this is the essence of being able to refine the Essence of the Essence Pill. This kind of experience, no matter which sect it is placed in, will not be recorded above board, and it is definitely the secret of passing on the son but not the daughter-in-law.

After discovering such a small trick, Yang Chen started refining again, which was very good, the fourth time he insisted on the five hundred and twenty-sixth kind, the fifth time he reached five hundred and eighty-seven kinds, and the sixth time he insisted on six hundred and three kinds.

Three more failures, and then Yang Chen began to sum up the lessons and lessons again, and after thinking for a while, he found a small deficiency that he had missed in front.

After continuing to go through it in his mind from the beginning, Yang Chen continued to refine. I don't know how many times I have refined it this time. Every time he failed, Yang Chen would carefully summarize the lessons learned, and he didn't know how many failures he had experienced, but Yang Chen was finally able to fail after adding the nine hundred kinds of medicinal materials.

After going on and on, Yang Chen finally found the trick, and finally had a grasp in his heart for the first time. The rest of the medicinal herbs, Yang Chen also knew what to do.

After a careful period in his mind, Yang Chen began to sit cross-legged and practice. After all the ** were practiced and the magic weapons were maintained, Yang Chen realized that his mental state had reached the best and began refining again.

This time, I don't have the jerky feeling I had before, and I'm full of confidence. Yang Chen's every step was extremely clear, all the medicinal materials were added at the right time, the heat of the treatment was just right, and the alchemy technique was clean and neat. After the last medicinal herb was added, it was very normal in the Dan furnace, and under Yang Chen's careful care, after nine hundred and eighty days, a furnace of Dan medicine was finally baked.
