Bidding farewell to the senior brother who sold "seeds", Wu Di can finally enjoy the night scene here, and he is in a good mood at present, although the people he sees are all in pairs, but he is not envious at all.

How to say, sooner or later they will all be torn apart.

After strolling around for a while, Wu Di felt that he was in a hurry, and he was almost tired of seeing the flames around him, so he chose to go back when he was bored.

When he returned to the room, he had no interest in reading Danshu anymore, anyway, he remembered those things after reading them once, and now they are still circling in his mind, and he is not afraid that he will forget, so he lay down on the bed and fell asleep.

The next day, he spent a day going out to inquire about the news of the pill, and heard from the disciples of the Tianhuo Taoist Temple that every pill of that kind was strictly controlled by the Taoist Temple, and it was difficult for ordinary disciples to get their hands on it, so if they wanted to get it, they had to beg Sun Liyun, where should she have it.

Of course Wu Di won't go to Sun Liyun, if she finds her, it is estimated that it will not be easy to say, and if she doesn't get it, she will be burned and arouse suspicion in vain, so this matter needs to be carried out in secret.

Wu Di also understood that this elixir was controlled, so after receiving the fire poison of the Tianhuo Dao Temple, he could only find the Tianhuo Dao Temple, and basically those who wanted the elixir had to pay a great price, this was their difficult intentions.

Even if it is a person from the Heavenly Fire Dao Temple, it is very difficult to get a Heart-devouring Returning Yuan Pill, if you can refine it yourself, it is still a little possible.

So Wu Di went to the book collection to look for Danshu, and the book disciples here can read it freely.

There are many types of books here, and they are very comprehensive, but in terms of pill refining, they are only some theories and experiences, and it is basically impossible to find the Dan prescription of the Heart-devouring Guiyuan Dan. Wu Di searched the entire book collection, and only got a few prescriptions for the healing pills of the bad street.

"Forget it, first gain Sun Liyun's trust, and follow her to learn alchemy. ”

Wu Di knew that this was just blindness, so he went back to rest.

On the third day, Sun Liyun came to the residence to look for him, and Wu Di went to the Tianhuo Danguan with her.

They came to an independent alchemy room in Danguan, there was a large shelf inside, on which were placed many bottles and jars, and in the middle there was an alchemy furnace that was not big or small, and the Dan fire below was vigorous, and billowing purple smoke came out of the mouth of the Dan furnace.

The sunshine incense burner produces purple smoke.

Somehow, Wu Di looked at this stove and remembered this poem, which was quite appropriate when he thought about it.

"Wencha, have you read the Dan book I asked you to read these days?"

When she came here, Sun Liyun didn't talk nonsense with Wu Diduo, and asked him bluntly.

Wu Di nodded, "I've finished reading it, Mr. Sun, just ask me." ”

Seeing Wu Di's confident look, Sun Liyun nodded with satisfaction, "Since that's the case, then I'll test you first." How can you tell the difference between a lemon and a celebrity?"

Wu Di smiled, he really looked down on him, and actually asked such a simple question.

"Although the appearance of the herb and the celestial leaf grass is similar, the herb has a strange flavor and the root is dark red, while the root of the celestial leaf grass is orange-red. On top of that, herbs are edible, while celebris is not edible because of its violent toxicity. The two can be separated to refine a total of more than 8,000 known pills, and the two can only be mixed to refine one pill: Tianxiang Yiqi Pill, which is on page 82 of the first volume of the Complete Explanation of Herbal Medicine and on page 5 of the second volume of the instructions for the elixir. ”

Wu Di said a large number of things without hesitation, which surprised Sun Liyun.

In fact, there is no very fine difference between these two herbs, the difference between these two herbs written in the book was easily said by him, and he even remembered which page it was, Sun Liyun flipped it, good guy, it was really on that page.

Looking at Sun Liyun's shocked look when she flipped through the book, Wu Di scoffed, if she said all the paragraphs and lines on that page, wouldn't it scare her to death?

"Let me ask you again, how much do you know about the ghost grass?"

Sun Liyun knew that the simple question could not be difficult for Wu Di, so she deliberately asked something out of the way.

This ghost grass only mentioned one or two sentences roughly in these five books, but Wu Di saw more things when he was looking for Danfang, and he didn't think about it at this time, so he directly recited it.

"Ghost grass is produced in the ghost valley, and it is difficult to find it in the rocks during the day, and at night it emits a fluorescent glow like ghost fire to hunt for food, which is highly poisonous. These are on the last page of the second volume of the Complete Explanation of Herbal Medicine, and I also know that the ghost grass will produce a huge amount of heat when burned, producing violent light and heat, and producing irritating poisonous gases, which are often used to get rid of insect pests, and the number of pills that can be refined is less than five hundred. ”

Sun Liyun swallowed a mouthful of saliva, she didn't expect that this would not be difficult for Wu Di, what Wu Di said later was not even clear to her, after all, ghost grass is difficult to find, and there are few types of alchemy, so few alchemists will study it, unless they have to use it before they notice it.

Therefore, the ghost grass also has the title of a ghost in the alchemy world, and Wu Di can answer this question so perfectly, he must have a deep understanding of the foundation of herbs and pills.

"How do you know all this?" Sun Liyun was a little curious, had this guy ever studied alchemy before?

"Oh, in the past two days, I went to flip through the Dan books in the book view, and then I remembered it. ”

Wu Di's answer made Sun Liyun speechless, "flipped over" and "remembered", is this pharmacological knowledge so easy to master?

If you want to talk about what is the most boring thing in alchemy study, the first thing is pharmacology, the combination and origin of countless herbs, just remembering their names takes a lot of time, and if you want to alchemy, you must have sufficient study and research on all herbs.

Therefore, the powerful alchemists are all old monsters who have been immersed in the Dan Dao for many years, don't look at her so young, it seems that she is less than thirty, in fact, she doesn't know how many furnaces of Zhuyan Pill she has eaten to get to where she is now, her real age is enough to be Wu Di's grandmother.

Next, Sun Liyun, who did not believe in evil, asked Wu Di a lot of questions, from herbal medicine knowledge to alchemy knowledge, from day to night, basically asking all the things mentioned in the five books.

Wu Di still answered fluently, without any hesitation or embarrassment when answering, and was accurate to every page, which made Sun Liyun breathtaking.

This guy actually completely ate the content of these five books in just over two days, and he is a monster.

Every person who has the talent of an alchemy master is a natural alchemist, and there will be no problem at all in operation, what can stump them is the vast and complex knowledge of the elixir, so as long as there is theoretical support, their practice will not be bad. This is the valuable experience and wealth accumulated by the Tianhuo Taoist Temple for countless years.

By this time, Sun Liyun had completely believed that as long as this guy was willing to work hard and study, becoming the next alchemy master was almost a certainty.

Blue is better than blue, if she Sun Liyun can really teach an alchemy master, then she will definitely be able to leave a name in the history of the Tianhuo Taoist Temple.
