There are too many three-rank pill pharmacists, because there is no four-rank pill formula, so they can't refine the four-rank pill pharmacist, even if this three-rank pill pharmacist has met all the hard conditions to become a four-rank pill, like the realm, like the divine soul, like the control of flames. But as long as there was no four-pin pill, he wouldn't be able to refine the four-pin pill. Unless some rare immortal genius can have the opportunity to create a new four-rank pill recipe by himself after failing thousands of times, but this is too rare.

The roll of parchment that Lin Yin picked up casually, the highest-grade Danfang, is the sixth grade. And Lin Yin immediately unfolded the other three rolls of parchment, two volumes had several six-pinned pills, and one volume had seven-pinned pills.

A complete pill pill pill prescription far exceeds the value of hundreds of pills of the corresponding grade. Moreover, there is no market for it.

Lin Yin seems to have finally felt the creation of the underground palace this time, and he is still not so stingy with himself, except for the regret of the heavenly level weapons, these six-grade and seven-grade pills alone are priceless treasures.

Lin Yin immediately forced himself to calm down, and then from several kinds of parchment that recorded Dan Dao, he picked out the most detailed description of the foundation of Dan Dao, looked at it carefully, and memorized every word and sentence in it.

In addition to those refining techniques, the alchemy taboos that need to be paid attention to, as well as the detailed explanation of the Danfang and the various complicated descriptions of the ingredients of the dispensing, Lin Yin focused on the description of how to judge the level of the pill after the finished pill.

This is what Lin Drink urgently needs now.

Lin Yin looked carefully at these parchments that recorded the Dan Dao, not to start practicing the Dan Dao, but to give himself the ability to judge the grade of the Dan Dao.

Looking at the rolls of parchment, Lin Yu unconsciously stopped because of the strong hunger. In the Martial Spirit Realm, although it is impossible to achieve complete Bigu, there is no longer a need for ordinary people to eat three meals a day, and in the sea of body qi, the self-absorbed heaven and earth Yuan Force can meet the energy required by the body as much as possible. This has a hunger pang, which is enough to prove that Lin Yu has studied these parchments that record Dan Dao, and a long time has passed.

Fortunately, this is a thousand miles of mountains and forests, and it can even be said that it is a primeval forest, with a variety of animals.

Neatly slaughtered a wild boar, Lin Yin filled his stomach, and continued to be silent in the Dan Dao.

Gradually, Lin Yu understood how to judge the grade of the pill, in addition to the most obvious pill incense, there were also the pill patterns, the color of the pill, and the situation that the high-grade pill would attract the vision of heaven and earth.

From the three hundred bottles of pills, Lin Yu began to pour out one pill after another for identification, those pills were covered with prohibitions, and there was not even danxiang, Lin Yu still found it difficult to firmly come out of the specific grade, but among the three hundred bottles of pills, there were also many pills that were diffused with danxiang and did not add another ban on the pills. For these pills, Lin Yin finally had some rough judgments.

Among the three hundred bottles of pills, fifty bottles of pills were exceptionally prohibited, and these Lin Drinks couldn't judge, but they also understood that these fifty bottles of pills were truly high-grade pills. And these fifty jade bottles, there is only one pill in them.

The remaining two hundred and fifty jade bottles, all of which contained ten pills. After a long period of comparison, Lin Yin judged that one hundred bottles of them were five-grade pills, one hundred bottles of six-grade pills, and fifty bottles of seven-grade pills.

Coming to this conclusion, Lin Yin was stunned for a long time.

This is equivalent to Lin Yin now having 1,000 five-grade pills, 1,000 six-rank pills, and 500 seven-rank pills!

The five-rank pill is enough to make the martial cultivators of the great martial master realm red-eyed, while the six-rank pill will make the martial king scramble, and the seven-grade pill, Wuzun will not be able to sit still.

"Earn big. Lin Yu was ecstatic in his heart. Then he smiled dumbly, remembering that he had these pills because he didn't have any understanding of Dan Dao before, but he didn't know the value of these pills. Nowadays, I really feel that I am shocked that what I have obtained is too precious.

"Five-pin pills. Lin Yu looked at the hundred bottles of five-grade pills that had been sorted out and divided by himself in front of him, and muttered to himself. Then he carefully took out a five-pin pill and put it in his mouth.

Six-pin, seven-pin elixir, Lin Yu was afraid that he would not be able to stand the huge energy of the elixir. But with the five-pin pill, Lin Yu still has some confidence that his body can resist it.

After reading so many descriptions of Dan Dao, Lin Yin also discovered that if you only talk about the energy of the pill, the energy of the various medicinal materials for refining the pill gathers together, the pill of one grade higher is equivalent to ten times the energy of the pill of the lower grade.

In other words, if Lin Yin was able to swallow ten four-pinned pills, he could withstand the energy of one five-pinned pill. Of course, if it is a comparison of pure value, no one is willing to exchange the five-pinned pill for ten four-pinned pills. Not to mention anything else, the pills for refining the five-pinned pills alone are far less scarce than the four-pinned pills, which restricts the one-to-ten exchange of the energy of the medicinal herbs alone.

This exchange has also historically reached one to twenty, or even thirty. And as the grade of the elixir increases, this exchange rate will also increase linearly. Just like twenty second-grade pills, you can exchange them for one third-grade pill. But twenty third-grade pills can't be exchanged for one four-grade pill.

A five-pinned pill was in his stomach, even though Lin Yu had inferred about the energy of the pill, he was still a little nervous about the effect of the five-pinned pill.

"Boom!"

Suddenly, the Heaven and Earth Yuan Force surged wildly, and Lin Yin's body directly began to absorb the Heaven and Earth Yuan Force independently. This is the effect that Lin Yin can only achieve by swallowing ten four-rank pills, and now, he has really reached such a level with only one five-rank pill.

When this violent Heaven and Earth Yuan Force frantically poured into Lin Yin's body, along with the energy of the Five Rank Pills completely dissolving in Lin Yin's body, two terrifying energies instantly made Lin Yin feel that his body was on the verge of collapse.

And sleeping in the sea of Lin Yin's qi, the palm-sized Fang Tian Painting Halberd really did not disappoint Lin Yin, and at this time began to frantically devour all the energy that poured into Lin Yin's body, whether it was the gathered Heaven and Earth Yuan Force, or the energy of the Five Rank Pill, this Fang Tian Painting Halberd, no one refused.

And this time, Lin Yu simply didn't wait for the Heaven and Earth Yuan Force that poured into his body to start weakening, and continued to swallow the Five Rank Pill. Anyway, with the devouring of this Heavenly Painting Halberd, Lin Yin didn't have to worry about whether his body could bear it.

One by one, the five-rank pills were continuously thrown into Lin Yin's mouth, if there were others present at this time, no matter what kind of realm the martial cultivator was, he would definitely be shocked and his scalp would be numb, a martial cultivator of the martial spirit realm was just a heavy heaven, and he should not even be able to withstand the energy of the four-rank pill, but now he swallowed the five-rank pill so frantically, which is tantamount to suicide in many people.
