Chapter 457

After Nie Qianyu finished speaking, she took Zhang Xiaohua to the place where the sealworts were planted. She helped Zhang Xiaohua dig out a few sealworts in the herb garden that were born in one or two years. She turned around and handed them to Zhang Xiaohua, asking, "Brother Ren, this sealwort is not easy to wash. Take it first. When we get to a place with water, I will wash it for you."

Zhang Xiaohua felt strange and blurted out, "Why do I need to wash it?"

However, she immediately understood that Rejuvenation Valley was "frying pills". If the sealworts were not washed clean, there would be one more ingredient in the "Fasting Pill". If it was discovered by others, it would become "Earth Injection Pill", just like the "Water-Injection Chicken" that Young Master Li Jinfeng talked about.

Seeing Nie Qianyu's puzzlement, Zhang Xiaohua explained, "The ancient method of refining pills is about using alchemy fire to quench the impurities in the herbs. Although there is a lot of soil, it can be quenched with alchemy fire. You don't need to trouble yourself to wash it clean."

Nie Qianyu blushed and said with a smile, "I have seen the steps of the ancient method of refining pills, but I have never thought of this. It seems that there is indeed a problem with the method of refining pills in Rejuvenation Valley."

Receiving the sealworts from Nie Qianyu, Zhang Xiaohua had an idea. The sealworts could be stored for a long time, but many of the herbs used for refining pills were very delicate. If they were not stored properly, the vitality in the herbs would be lost quickly. Rejuvenation Valley did not have to consider this problem, but she had to prepare in advance.

After thinking for a while, it seemed that there was a method to make a jade box in the appendix of the "Outline of Refining Weapons". She had to refine a few backups later.

The other ingredients of the Fasting Pill were very common. Since Rejuvenation Valley planted them in the outer valley, Nie Qianyu had to continue walking outside with Zhang Xiaohua.

At this time, the sun had already set in the west. The two of them walked on the rugged path in the inner valley. Mottled shadows fell on their bodies from time to time. Nie Qianyu felt that the path in the inner valley had never been so comfortable. Her mood was like a happy little bird, flying in the valley filled with the smell of herbs.

There was still some distance between the Inner Valley and the Outer Valley, but Nie Qianyu couldn't wait for it to be farther. Ever since Zhang Xiaohua entered Rejuvenation Valley, she had been studying and cultivating with all her might. Although the place where she lived was very close to Nie Qianyu's, there weren't many opportunities for them to meet. Compared to the time when they used to travel together and chat and laugh in the same carriage, Nie Qianyu really missed the time when they were traveling together.

This journey, which was neither too long nor too short, allowed her to find the warmth of the past.

However, Zhang Xiaohua's topic was not romantic at all.

"Little Fish Nie, I've just looked at the recipe for the Fasting Pill. Aside from the main ingredient, sealwort, can you tell me what the effects of the other ingredients are?

In addition, I have a question. If we directly use the sealwort to make the Fasting Pill, will it be successful? "

Hearing this, Nie Qianyu was embarrassed and said, "Big Brother Ren, I can't answer your second question. I haven't tried it, and it seems that Rejuvenation Valley hasn't tried it either. However, I can answer your first question simply. The effects of these herbs are recorded in the ancient books …"

Then, Nie Qianyu explained the growth, effects, and characteristics of the other ingredients in detail. These were all recorded in the ancient books, so naturally, Zhang Xiaohua knew about them. However, listening to Nie Qianyu's soft voice and her clear and logical explanation, Zhang Xiaohua nodded secretly. She was not called smart for nothing.

However, Nie Qianyu did not know the method of the five elements in the elixir. Perhaps she knew about it, but she did not think about it. In her explanation, there was no mention of it at all.

While listening to Nie Qianyu's explanation, Zhang Xiaohua pondered in her heart. Slowly, she realized something and could not help but smile. "Little Fish, after listening to you, I'm very impressed. To be honest, I've been reading books about these herbs, but after all, the time is too short, so I can't reach your level."

Hearing this, Nie Qianyu felt sweet in her heart, but she comforted him. "Big Brother Ren, you don't have to be modest. It's already very rare for you to know so much in such a short time."

Zhang Xiaohua shook her head and asked, "However, Little Fish, can you think deeper?"

Nie Qianyu was stunned and puzzled. "Deeper?

What deeper? "

After choosing her words, Zhang Xiaohua probed, "Don't you know how to write prescriptions?

Don't the herbs in the prescriptions have to match the five elements and adjust Yin and Yang? "

Nie Qianyu's eyes lit up, but she hesitated. "The herbs in the prescriptions are used to treat people. Naturally, we have to consider the pros and cons. If we're not careful, won't we kill the person?

Moreover, the medicine has to be right for the illness to adjust the changes of the five elements in the person's body and return to normal.

Oh, Big Brother Ren, you mean … "

Zhang Xiaohua touched her chin and looked like an expert. She said meaningfully, "Decoctions are for ordinary people, while elixirs are for people in Jianghu. Decoctions are used to treat people, while elixirs are used to adjust internal energy or Qi and blood. In essence, they should be the same, right?"

Nie Qianyu still shook her head. "It's different, it's different. Decoctions are just ordinary things. How can they be compared with elixirs?

Moreover, what Big Brother Ren said is relatively common in pharmacology. It's said that decoctions evolved from elixirs. If it's suitable for elixirs, why didn't the alchemy technique mention the five elements?

Could it be that everyone else is stupid? "

"This?" Zhang Xiaohua scratched her head.

That's right. Even I can think of such a simple reasoning. How can other experts not think of it?

Seeing that Zhang Xiaohua was speechless, Nie Qianyu smiled and said, "However, this is the first time I've heard of such a theory in alchemy. It's very novel. Big Brother Ren, reading like you is really reading. You can infer other things from one example and comprehend other things by analogy."

Zhang Xiaohua straightened her chest and said, "That's right. Your Big Brother Ren has read the 《Three Character Classic》 for many days."

"Pfft." Although Nie Qianyu was used to hearing this joke, she still couldn't help but laugh.

After that, the two didn't talk much about it. They just chatted for a while and walked out of the valley.

There were also many herbs planted in the herb garden in the outer valley. However, they were all common and not rare. Because of the rich vitality in Rejuvenation Valley, these herbs grew very well.

These herbs were managed by the herb garden's Fei He. Fei He was a tall and thin middle-aged man who was not good with words. Zhang Xiaohua had seen him before. Her only impression of him was that he lived up to his name.

Seeing Zhang Xiaohua and Nie Qianyu come together, Fei He put aside his work and went to receive them. First, he helped the two of them pick a few herbs. Then, he didn't dare to disturb the two of them and prepared to leave.

However, Nie Qianyu pulled him and said, "Second Senior Brother, don't be in a hurry to leave."

Fei He asked curiously, "Is there anything else, Little Junior Sister?"

Nie Qianyu pointed at Zhang Xiaohua and said, "Second Senior Brother, you know Big Brother Ren. If he comes to the garden to pick herbs in the future, don't block him."

Fei He smiled and said, "Who in Rejuvenation Valley doesn't know Ren Shaoxia? Little Junior Sister, you're worrying too much. Hehe."

Seeing Fei He's strange smile, Nie Qianyu gently stamped her feet and said angrily, "Second Senior Brother ~ ~"

Fei He was much older than Nie Qianyu. He watched her grow up and cherished her like his own child. Seeing her girlish attitude, he laughed in his heart and said, "When Ren Shaoxia was in Big Senior Brother's Qihuang Courtyard, he often came to the garden to pick herbs. Little Junior Sister, don't worry."

"I see."

Nie Qianyu somewhat understood, but she still didn't let Fei He go. She asked softly, "Second Senior Brother, you've been in charge of the herb garden for many years. You're very familiar with the properties and characteristics of various herbs. I want to ask you a question."

Fei He smiled and said, "Little Junior Sister, you've been asking 'why why' since you were young. Now that you've grown up, you still haven't asked enough?"

Nie Qianyu smiled and said, "Second Senior Brother, you have a good memory. It seems that you haven't aged yet."

"However, I really don't know how to answer the question that Big Brother Ren asked me just now." Nie Qianyu solemnly explained the theory of the five elements in alchemy.

Fei He pondered for a moment and said, "This question, Young Hero Ren has asked a good question. I have also paid attention to it before, but I only know about medicinal herbs and am not proficient in alchemy. I only know a little about Qihuang, so I did not dare to think too deeply about it.

As for why there's no theory of the five elements in alchemy, I think it's probably like this. "

Hearing that Fei He had also paid attention to this question, Zhang Xiaohua couldn't help but be interested.

Fei He said, "The application of herbs in pharmacology is based on the principle of alchemy. It applies herbs to human diseases. The theory of the five elements starts from acupuncture, then spreads to the prescription of decoction, and then back to the herbs in the prescription. Most of these herbs are common and don't involve the magic herbs used in alchemy. Alchemy has existed since ancient times. Our predecessors had great wisdom, but they couldn't classify magic herbs into the five elements. Therefore, the five elements may only be used for common herbs."

"Thinking of this, I stopped thinking about it. There are still many things to be done. Who has the time to do something that our predecessors disdained or believed to be impossible?

Oh, Ren Shaoxia, I'm not talking about you. I … "

Zhang Xiaohua was speechless. What Fei He said was very reasonable and the logic was very simple. "Although common herbs can be classified into the five elements, it's only according to the patient's condition. Magic herbs are not used to treat diseases, so they may not be classified. Moreover, if they can be classified, alchemy is already very mature, which is many years earlier than Qihuang. Why can't our predecessors distinguish them?

It must be because they can't. "

However, Zhang Xiaohua faintly felt that things were not as simple as what Fei He said. He might not know what the Tao of Heaven was, but he had faintly glimpsed the trajectory of the Tao of Heaven. He didn't know what the predecessors thought, but he did feel that the theory of the five elements was everywhere from the Tao of Heaven. It must be in the herbs used for alchemy.

Suddenly, Zhang Xiaohua's chest rose a kind of ambition. Do what no one has done. Maybe I can create an era!

PS: These chapters are extremely awkward. I guess I've reached a bottleneck. This is the second time that I've written this book.

In addition, I'm dizzy. Brothers and sisters, don't you have monthly votes?
