Two jade slips, one is called "Introduction to Alchemy", and the other is "Treatise on Medicinal Properties".

Ye Chen took a general look and found that "Introduction to Alchemy" was a book for teaching alchemy in the true sense, and it was aimed at novice alchemists.

It records the principles of alchemy, techniques, and various precautions.

It also comes with two basic elixirs, the Ascension Pill and the Tonifying Elixir.

After reading this book, Ye Chen finally had a correct understanding of alchemy.

The so-called alchemy is not a particularly mysterious thing in essence, and the simplest pill is actually the use of auxiliary drugs and many means to extract the medicinal properties of the main medicine and form a state suitable for the use of monks.

For example, the Ascension Pill is to extract the spiritual energy contained in the Ascension Herb and use auxiliary medicine to make it gentler and easier to absorb.

Of course, there are definitely more complex elixirs than this, such as a high-grade elixir called the Incarnation Pill, which can generate a controlled out-of-body avatar for the monk for a short period of time after consumption.

This is not something that can be explained by the medicinal properties of a spirit herb.

But at the very least, most of the low-grade pills in the Qi refining period were in this simple mode.

The book is more specific about the alchemy steps, but the premise is the spiritual eye technique.

After Ye Chen hastily flipped through it, he had no choice but to give up the research for the time being, and instead picked up the "Theory of Medicinal Properties" again.

Unlike "Introduction to Alchemy", "Theory of Medicinal Properties" does not talk about anything related to alchemy, but is a book that is biased towards theoretical research.

It talks about the theory of the "medicinal properties" of different spiritual herbs and pills, and makes many conjectures and hypotheses around the medicinal properties.

It's very cumbersome, Ye Chen estimates that if he hadn't studied in his previous life and had a set of relatively scientific thinking logic, it would have taken a lot of effort to understand this book.

The contents of these two jade slips are not much more than the "Medicine King Sutra", Ye Chen feels that he has to read them completely and figure them out, no matter how he says it, it will take a month.

But as long as you think it through, then alchemy can be regarded as really entering the door, even if the manual practical experience is zero, at least there should be no problem in going out to give people a head in science popularization.

……

For the next period of time, Ye Chen spent the days of studying the "Medicine King Sutra" at night and studying "Introduction to Alchemy" and "Theory of Medicinal Properties" during the day.

These three jade slips were used by him day and night, and they had been polished smooth and clear.

Every day is very busy, but he enjoys the feeling of learning.

Except for occasionally going out to meet Li Meng, he almost stayed at home, and it took half a month for him to finally succeed in cultivating the "Medicine King Sutra", and he accumulated a trace of mana in his body again after a long time.

Different from the transparent and slightly cyan "Qingyun Qi Decision", the mana cultivated in the "Medicine King Sutra" is green, with a slight flickering of fiery red, which is very much in line with the characteristics of its wood and fire dual system exercises.

When flowing in the meridians, it can also moisturize the meridian body, making Ye Chen feel that his physical fitness is a little stronger than before.

Since then, his cultivation has been smooth, one spirit pill a day, and his cultivation has improved quite quickly.

After a few more days, the "Spirit Devouring Decision" of the "Medicine King Sutra" was also preliminarily mastered by him.

The Spirit Devouring Decision is a method that has no outward effect, and is basically only used when meditating and cultivating.

After use, a strange vortex can accumulate in the abdomen of the body.

At this time, when taking the pill, the medicinal power will automatically pass through this vortex, and it can absorb an extra part of the medicinal effect, up to 30%.

Just this point, this is a very powerful law decision, but unfortunately, only those who have cultivated the "Medicine King Sutra" can use this law decision.

Otherwise, Ye Chen estimated that the Spirit Devouring Decision would become a necessary method for everyone in the Immortal Cultivation Realm to learn, there was no threshold, and the effect was quite significant.

In addition, the Spirit Devouring Duel also has a special effect of Hardcore - after using it, you can directly devour the Spirit Grass without wasting too much Aura!

Ye Chen made an attempt and found that directly devouring the Spirit Ascension Grass produced on the farm after using the Spirit Devouring Decision could actually absorb a large part of the spiritual energy in it.

The amount of one Ascending Spirit Grass absorbed in the end is about equivalent to the effect of three Ascending Spirit Pills!

If it is calculated by value, the Ascension Spirit Grass produced on his farm should have been sold on the market for one plant with three spirit stones, but it is exactly the same as the value of three Ascension Pills.

Compared to the previous time when he used various methods to take the Ascension Spirit Grass, the utilization rate of one plant could only be equivalent to less than two, or even only one Ascension Pill, which was much higher.

He also omitted the steps of grinding and condensation.

This effect may be relatively weak for other disciples, but for him who has a farm, it can be said to be a divine skill among divine skills!

Ye Chen directly and decisively gave up taking the Spirit Ascending Pill, and instead directly used the Spirit Devouring Decision to take the Spirit Ascending Herb.

For him, the Ascension Pill can be taken out and sold for money, but the Ascension Grass cannot.

Since the effect is similar, the priority of using it must be to use the Ascension Grass, which has no cost to him.

Using this method to cooperate with enough Spirit Ascension Grass, Ye Chen's cultivation speed can be said to be a thousand miles a day.

As far as his actual experience was concerned, the speed at which his Yuan Shen increased every day at this time was much faster than when he drank the spiritual liquid every day in the past.

Only half a month had passed, and Ye Chen had successfully broken through to the second layer of qi refining!

This time, his speed of breaking through from the first layer of Qi cultivation to the second layer was much faster than before, ignoring the time when the Medicine King Sutra had not yet officially started cultivation, it only took less than twenty days in total.

This speed can already be said to be against the sky, and it is completely at the level of crushing ordinary disciples of the outer and inner gates.

But this was piled up by countless Ascending Spirit Grass, and in fact, he was not much faster than those other Outer Dan Hall disciples outside.

Among the disciples of the Wai Dan Hall, it was not uncommon for them to reach the second floor before him.

The quota of seven bottles of the Ascension Pill in one month was enough for all the disciples of the Outer Dan Hall to cultivate and use one pill every day.

Their cultivation speed was not much worse than Ye Chen's.

Of course, this is the price that the Wai Dan Tang paid in order to let them rise to the middle stage of Qi refining as soon as possible, and when these disciples are in the middle stage of Qi refining, they may not necessarily get so much rationing.

Except for a very small number of core disciples of big families and big sects, there are not many monks who can cultivate like this.

It's completely using spirit stones to smash cultivation.

Even the inner disciples don't have this treatment.

By now, Ye Chen already had a clear understanding of his qualifications.

First of all, it must not be as bad as he thought at the beginning, but it is definitely not as good as some of the heavenly pride of those inner gates.

His qualifications should be slightly ahead of the middle of the entire sect, but they are actually quite good qualifications.

If he cultivates honestly and hard in the Qingyun Sect, with his current qualifications, if he doesn't die halfway, there should be a high probability that he will be able to step into the late stage of qi refining in this life.

As for the foundation, it's hard to say.

It had been more than a month since he entered the Outer Dan Hall, and after Ye Chen had reached the second layer of Qi refining after his cultivation, he had finally completed the study of the two books "Introduction to Alchemy" and "Theory of Medicinal Properties".

Early one morning, taking advantage of the fact that there was no one in the West Courtyard, he left the West Courtyard early and went to Uncle Wang's residence.

According to the agreement, after he has read and understood all these two books, he can come to Uncle Wang to learn alchemy.

He had been looking forward to this day for a long time.
