Liao Xianrong's friend is named Lin Zhecheng, an elder of the Danshi Guild, and a 3rd rank Danshi.

In the Wuning Danshi Guild, he is a relatively well-known existence.

Because the quality of the pills he refined was all of the upper grade, all the pills refined by his hands were sold at a price thirty percent more expensive than those of the same kind refined by other pills of the same level, but they were still in short supply.

Therefore, under normal circumstances, if you want to obtain the elixir that he has refined with his own hands, you can only pay a deposit at a high price first, and then wait for him to schedule it and refine it for him.

As for how long to wait, he has the final say.

If he is in a bad mood, or does not want to stop the research work at hand for the time being, and is too lazy to refine the elixir, the customer who has made a deposit can only choose to wait patiently.

This Lin Zhecheng is like this.

However, he took it because he had real skills, unlike some people, such as Jiang Weifeng, who didn't have much ability, but he liked to pretend to be forced, and as a result, he was slapped in the face, resulting in a loss of face.

Luo Xiaoyan rushed to the Danshi Guild, and under the leadership of the office staff of the Danshi Guild, when he found Lin Zhecheng, Lin Zhecheng was immersed in researching an ancient Dan recipe.

Sensing that someone was coming in, Lin Zhecheng just glanced up, waved his hand to Luo Xiaoyan, who entered the office, and then stopped looking at him and was busy with his own affairs.

"You wait slowly, I still have something to do, so I'll leave first. The office staff of the Danshi Guild knew Lin Zhecheng's temper and his character, he really didn't know when Lin Zhecheng would end the matter at hand to deal with Luo Xiaoyan, who came to him, so he whispered hello to Luo Xiaoyan, and then left by himself.

Before Luo Xiaoyan came to Lin Zhecheng, Liao Xianrong told him that if Lin Zhecheng was busy with his own affairs, he should not disturb him easily, so as not to bore him and lead to the worst outcome.

Therefore, seeing that Lin Zhecheng was busy with his own thoughts, he didn't pay attention to his meaning at all, and he was not in a hurry, he got up and walked around the office, looking east and west, and finally came to the bookshelf that Lin Zhecheng placed in the office, and picked up a copy of "Alchemy Techniques" and read it.

At the beginning, Luo Xiaoyan just casually opened a few pages, and then he felt dizzy, and found that he couldn't calm down at all, and patiently read such boring books.

So, in order to keep the knowledge in the books as his own, Luo Xiaoyan directly began to consume the Divine Energy Card to improve his learning ability, and then did his best to read the large number of books about alchemy knowledge collected by Lin Zhecheng.

Minutes and seconds passed.

It took nearly an hour for Luo Xiaoyan to read all the books that Lin Zhecheng had collected and regarded as treasures, and all the knowledge was integrated into the sea of knowledge and became his own knowledge.

And in this process, just 60 or so Divine Energy Kapuka were consumed, and this kind of consumption was extremely cost-effective for Luo Xiaoyan.

After reading the book, Luo Xiaoyan was really idle and had nothing to do, but seeing that Lin Zhecheng was still busy studying the paper materials that were spread on the desk and the paper looked a little yellowed, he flipped through an ancient dictionary in his hand while reading.

The ancient dictionary mentioned here is actually a Chinese dictionary when Luo Xiaoyan did not cross over, and almost every student in that era had a Chinese dictionary.

"Senior, what are you looking for? Do you want to find information related to the medicinal materials on the Danfang in your hand in the dictionary? Instead of wasting time looking up the information on the medicinal materials in the dictionary, it is better to go directly to an ancient book called "Compendium of Materia Medica". Luo Xiaoyan walked to Lin Zhecheng's side, looked at it casually, and knew that Lin Zhecheng was busy looking for information related to several herbs recorded on the Gu Dan Fang, so he said directly to him.

"Do you know the Compendium of Materia Medica?" After listening to Luo Xiaoyan's words, Lin Zhecheng finally stopped being busy, raised his head, looked at Luo Xiaoyan curiously, and asked him.

"I know of an ancient book that contains a lot of detailed information about herbs. Luo Xiaoyan responded casually.

"I also know, but ancient books such as the "Compendium of Materia Medica" are too precious, and it is simply unrealistic for everyone to have a copy. Lin Zhecheng frowned slightly, as if he remembered something, and immediately said to Luo Xiaoyan, "Since you know the ancient book "Compendium of Materia Medica", you must have seen it with your own eyes. Tell me the truth, where have you seen the Compendium of Materia Medica, and where is that Compendium of Materia Medica in anyone's hands now?"

"Uh...... This ......" Luo Xiaoyan didn't know how to answer for a while, because he had indeed seen the "Compendium of Materia Medica" in the bookstore, but that was before he had traveled over in his previous life, and he was not a medical student, so he naturally would not be interested in books like "Compendium of Materia Medica".

"What's the matter? That's a big man, you don't even dare to mention his name casually?" Lin Zhecheng asked with a frown.

"It's not. Luo Xiaoyan shook his head and said, "Because I have never seen the Compendium of Materia Medica, I only heard a Dan master mention this ancient book, so I remembered it in my heart." Just now I saw you holding a dictionary to look for information about herbal medicine, and I remembered this ancient book, and I thought that this "Compendium of Materia Medica" should be rewarding, so I said it casually. ”

"Oh...... It turned out that this was the case, and Lao Tzu was happy. Lin Zhecheng shook his head a little disappointed, and then continued to bury his head in his own business, while explaining to Luo Xiaoyan, "Don't you know, when disaster struck the earth, a large number of books and textbooks that were originally available everywhere were destroyed, and ancient books such as the Compendium of Materia Medica were one of them. In addition, such ancient books, in the eyes of Danshi, are treasures, and they are reluctant to divulge the information above, which leads to a large number of Danshi today, and it is extremely unrealistic to obtain a copy of the "Compendium of Materia Medica", hi......"

Speaking of this, Lin Zhecheng sighed helplessly, and then didn't say more, and continued to be busy.

Seeing this situation, Luo Xiaoyan was completely speechless.

After being silent for a while, Luo Xiaoyan no longer hesitated, and said directly to Lin Zhecheng: "Senior, how about we make a deal?"

"I don't have time to do any trading right now, where is it cool, where do you stay, don't bother me here. Lin Zhecheng didn't look up, and he didn't bother to care about Luo Xiaoyan's purpose for coming to him, so he responded casually.

"The senior still listened to what I was going to do with you first, and then it was not too late to refuse. Luo Xiaoyan spoke again.

"Say, I'm listening. Lin Zhecheng responded.

"I'll help you find the characteristics, medicinal effects, living habits, and what kind of environment can you find all the medicinal materials on the Danfang, and sort them out in detail, you just need to help me deal with the things that came to you, what do you think?" Luo Xiaoyan said.

"Are you kidding me?" Lin Zhecheng raised his head and looked at Luo Xiaoyan seriously, seeing that he was young and should not have much experience, he thought in his heart that even he couldn't do it, this guy in front of him was naturally impossible to do, and immediately looked a little annoyed and said a puzzled question to Luo Xiaoyan, if he hadn't seen the face of the person, it was estimated that it was the first time he came to the Danshi Guild, and he had already issued an eviction order, and directly blasted the person out.
