After dinner, Xu Shaotang takes Liang Danqing to the security company, and strictly forbids anyone to disturb him and Liang Danqing.

He didn't want to be disturbed at home, so as not to let Liang Danqing down. Only by carefully following Liang Danqing to learn alchemy, can he be worthy of Liang Danqing and himself.

Xu Shaotang also specially asked someone to prepare a video camera and plan to record the whole process. This is not to commemorate anything, but he knows that it is impossible for him to remember what Liang Danqing said. After recording this process, he can slowly watch the video to learn, so as not to disturb Liang Danqing and Yingluo who are preparing to wander around the world.

After opening the camera to them, Xu Shaotang took out his notebook and put it in front of him. He said seriously, "master, I'm ready."

He hasn't taken notes for many years, but this time, he took learning alchemy seriously.

Looking at Xu Shaotang's serious appearance, Liang Danqing was not quite used to it. She said with a smile, "you don't have to be so formal. We have the right to chat. In the process, you can ask me if you don't understand anything."

"Good!" Xu Shaotang nodded seriously.

"Let me test you first. What is alchemy?" Liang Danqing asked with a smile.

"This..." Xu Shaotang thought carefully and said: "alchemy should be to refine those pills that are beneficial or harmful to human body, right?"

"I didn't say it!"

Liang Danqing looked at Xu Shaotang speechless and smiled. "Alchemy" is actually refining the essence of all herbs. Then, with the understanding of the medicinal properties of various medicinal herbs, these essence will be condensed into Dan, so that it can achieve one plus plus effect far greater than two. This is true for both beneficial and harmful pills! "

"I see!"

Xu Shaotang looks at Liang Danqing embarrassed.

He knew nothing about the art of alchemy. He just looked at it literally and superficially, and did not realize the essence of alchemy.

"People are divided into men and women, Dan medicine is divided into inside and outside." Liang Danqing continued: "pills are divided into internal pills and external pills. External pills are mainly used to treat trauma, which is the simplest part of the way of pills. The real difficulty is internal pills. It's the real way to breathe out the old and accept the new, refine and transform the Qi, and make people reborn

"So, inner alchemy is more important than outer alchemy?" Xu Shaotang asked.

"So to speak." Liang Danqing said with a smile: "but there is no comparability between the two. Anyone who can refine inner alchemy can refine outer alchemy without a professor. Therefore, I'm not going to teach you how to refine outer alchemy. When you learn how to refine inner alchemy, you will naturally know how to refine outer alchemy."

"The two most important points of alchemy are the fire and your own understanding of medicinal rationality."

Liang Danqing continued: "in fact, the key to controlling the fire is to master the pharmacology of all kinds of medicinal materials by yourself. Therefore, the understanding of the pharmacology of medicinal materials is the most basic and important part of alchemy. No one can teach you this thing. Only through your own continuous learning, can you know the pharmacology of all kinds of medicinal materials When you are clear, you have to see the way of alchemy. "

"Ah?"

Xu Shaotang said with a wry smile: "this is the first step?"

There are so many medicinal materials in the world. It can even be said that everything in the world can be used as medicine. It is very difficult for him to understand the pharmacology of all things in the world.

Now he finally understood why Liang Danqing said that he and Yingluo could only barely know some of the skills of alchemy. I'm afraid they didn't even know the pharmacology of all things in the world?

Xu Shaotang, who was still in high spirits, began to play a drum in his heart. He couldn't help wondering whether he could really understand the pharmacology of all things in the world in his lifetime?

Looking at Xu Shaotang's bitter face, Liang Danqing couldn't help laughing and said: "so, I told you before that alchemy requires savvy. This so-called savvy is to look at the whole body. When you can do this, you can know the pharmacology of any medicine you want to give you."

"Is that so?" Xu Shaotang's heart is still a little empty, said: "I don't think I have such a high understanding."

"No confidence so soon?" Liang Danqing asked with a smile.

Xu Shaotang nodded slightly and said, "it's really a little bit. It seems that it's much more difficult than I imagined."

"What's so hard?" Liang Danqing waved his hand and said: "this is just the most basic skill of alchemy! What's really hard, you know? "

Xu Shaotang shook his head and said he didn't know. He couldn't think of anything more difficult. The antidote rationality alone is enough to make people feel collapsed. If there are more difficult things, the alchemy is too difficult.

"Qi!"

Liang Danqing sighed gently.

"Qi?" Xu Shaotang puzzled looking at Liang Danqing, asked: "what is gas?""Everything in the world has Qi!" Liang Danqing said: "I don't know the details. I only heard my master say that those who really become the road of alchemy can master the Qi of all things in the world and transform it into alchemy. That kind of alchemy can even make an ordinary person ascend to the heaven step by step! However, I have never felt the Qi of all things, let alone mastered these things! So Yingluo and I didn't even step into the door of alchemy. "

Xu Shaotang is full of astonished looking at Liang Danqing, let an ordinary person step up to heaven pill actually exist?

If that's the case, wouldn't their hard work be meaningless?

"Is that too abstract?" Xu Shaotang said bitterly.

Before I knew it, I thought that alchemy should be the same thing. But now with more and more things I learned from Liang Danqing, he found that alchemy is really an extremely extensive and profound knowledge. If I can really master it, I'm afraid I can be invincible in the world, right?

"Yes, that's what I told my master." Liang Danqing said with emotion: "but my master only told me that these were just passed down by his master from mouth to mouth. Even his master never felt the Qi of all things, and didn't know what it meant."

“……” Xu Shaotang was slightly surprised. For a moment, he didn't know what to say. He naturally couldn't pester Liang Danqing to ask about what his ancestors didn't know.

Liang Danqing had no choice but to smile and said: "well, let's not talk about this ethereal thing. Next, I'll teach you how to analyze the pharmacology of medicinal materials through their appearance..."
