Chapter 448: Mutational Alchemy

Zhang Xiaohua frowned and asked, "Father Nie, the temperature inside the valley seems to be a little higher than outside the valley. Is it because of alchemy?"

Master Nie Gu smiled and said, "Nephew Rich is really careful. The temperature at this time is similar to outside the valley. I thought you couldn't feel it. In fact, if you come here in winter, you will clearly see the difference."

Zhang Xiaohua was stunned, understood a little, and said, "Is the temperature inside the valley not the same as outside the valley?"

"It's really like this. The valley is like spring all year round, and the temperature is the same all year round. Otherwise, how could I take the name of "rejuvenation" in the name of "rejuvenation"?" Nie Qianyu said with a smile.

The three of them continued to move forward, and Lord Nie introduced: "This inner valley is quite large, with more than tens of miles east, west, south and north. There are countless rare herbs planted in it. Near the entrance of the valley is a place where disciples in the valley often go. Going further inside, there are some primitive jungles, and some birds and beasts live. Oh, the four-dimensional image of the villa comes from where I find it."

Zhang Xiaohua nodded. He had already used his spiritual sense to scan it over there. There were many wild birds and beasts inside, and it seemed that it was rare to see people traveling.

Master Nie Gu pointed to the endless medicinal field in front of him and said, "This is the core of my Huichun Valley. All kinds of herbs are planted. Because the inner valley is like spring all year round, the herbs in my Huichun Valley are considered famous all over the world. Of course, it is these herbs that have created my reputation as the Huichun Valley elixir."

Speaking of this, Lord Nie Gu looked proud.

Zhang Xiaohua nodded. He had been in Huichun Valley for so long, of course he knew the status of Huichun Valley in the world. Back then, Ou Yan from Huanxi Villa encountered the problem of herbs and did not think of Huichun Valley asking for help? However, the alchemy places in Huichun Valley were all between the walls of the inner valley, but his spiritual sense could not be penetrated and he did not know the content. Judging from the appearance of Master Nie Gu, it should be very powerful.

Then, Zhang Xiaohua pointed to the mountain wall on the right and said with a smile: "Father Nie, I see that there are many disciples coming in and out under the mountain wall on the left. I guess it is the alchemy place for our Huichun Valley, but what about this? It's silent, what's the use of?"

Lord Nie Gu looked at the stone wall on the right, then Zhang Xiaohua, and said seriously: "Nephew, you are not an outsider, it's okay to tell you. The stone wall on the left are all senior masters from my generations in Huichun Valley. They are old now and don't care about affairs soon and liven up in this place where all seasons are like spring."

"That's it." Zhang Xiaohua nodded thoughtfully. In fact, he could see clearly when he was scanning his spiritual sense, but he was not sure. Although Huichun Valley is not a great sect in the inheritance, it has a history of thousands of years. It would be impossible to say that there are no masters in the valley to take charge.

However, immediately, Zhang Xiaohua thought of the Piaomiao Sect again. The Piaomiao Sect is a major sect in the inheritance of immortality. It must have some background. Where have the masters of the previous generation gone? Why have the Piaomiao Sect been destroyed, and no one has come forward?

It's really strange!

"Then, Boss Nie, how many of our seniors in Huichun Valley live in the valley?"

Zhang Xiaohua asked casually.

"This..." Master Nie Gu was a little embarrassed, looked at Nie Qianyu, and said, "Nephew, you are not an outsider, but this is the secret of our Huichun Valley..."

Zhang Xiaohua suddenly realized and said, "Father Nie, if it involves confidentiality, it would be better not to tell me."

"Haha, in fact, the climate in this valley is pleasant, and there are many other herbs that can prolong life and condition the elixirs, so hehe, there are really many seniors living here."

"In addition," said Master Nie Gu in a mysterious way: "Nephew Ren, don't look at me as good as martial arts, Huichun Valley also has his own unique skills. In the past, there were many of us who ranked high in the world.

He looked like he was showing off.

Zhang Xiaohua was speechless.

Nie Qianyu pointed to the medicine garden not far ahead and said, "Brother Ren, look, this is the main ingredient for refining blood-replenishing pills. If this gastrointestinal sage is born in one year, it will not be of much use. The gastrointestinal sage used in the blood-replenishing pills are all more than five years. The climate of Huichun Valley is stable, which is most conducive to the growth of herbs. Moreover, for some reason, the inner valley is always better than the outer valley, so we can make excellent elixirs."

Zhang Xiaohua walked closer and released her spiritual sense slightly. But, the vital energy of the heaven and earth in this inner valley is more than three times that of the outer valley. Can these herbs grow well? Look at the terrain of this inner valley and the dense herbs, it is inevitable that the vital energy of the heaven and earth can gather.

"By the way," Zhang Xiaohua suddenly woke up and realized: "Master Nie Valley, why is the climate in this inner valley so popular?"

Master Nie Gu smiled but said nothing. Nie Qianyu said, "When Brother Ren enters the stone wall, I will naturally know how I refine the alchemy in the Huichun Valley."

Under the stone wall on the left are dozens of small cave entrances. From time to time, disciples from Huichun Valley come in and out. When they see the owner of the valley, they bow to salute.

When he approached, Lord Nie Gu pointed to the cave entrances and smiled and said, "Nephew Rich, this is where I refine my elixir in Huichun Valley. Guess why there are many caves?"

Zhang Xiaohua was stunned, thought for a while, shook her head and said, "I don't know, these different caves have different functions?"

Nie Qianyu said: "Brother Ren should not think too complicatedly. Just a simple guess, you must know it."

Zhang Xiaohua was about to shake her head, but her mind lit up and said with a smile: "Can it be that different elixirs are in different caves?"

Nie Qianyu immediately applauded and said, "I'm just saying that Brother Ren is thinking too much. This alchemy method is not as magical as written in the book. He only starts with simple ideas. Brother Ren can definitely guess it."

"Not the magical ones written in the book?" Zhang Xiaohua was stunned, and a question arose in her heart. Could it be that Huichungu's alchemy technique is different from the records in their books?

When Lord Nie Gu and Nie Qianyu led Zhang Xiaohua into a cave casually, Zhang Xiaohua was immediately stunned by the scene in front of her. Well, yes, she stood there blankly, without moving!

Seeing this, Master Nie Gu and Nie Qianyu were not surprised, so they just waited for him to react.

After a while, Zhang Xiaohua touched her nose and asked with a wry smile: "Father Nie, is this what you are talking about for alchemy?"

Then he said to Nie Qianyu: "Is this the usual thing about alchemy you mentioned?"

Nie Qianyu laughed and said, "Yes, alchemy is just like this. But are you scared by Huichun Valley's big moves?"

"Yes, yes." Zhang Xiaohua looked around carefully, even released her spiritual sense, and looked at it again and again.

Dear readers, what did Zhang Xiaohua see? He actually surprised this successor of the Immortal Dao, Zhang Xiaohua, who has truly refined the fasting pill?

I saw that this was a very large cave, which was slender. There were dozens of grooves on the mountain wall in front of Zhang Xiaohua. Each groove was placed with a cauldron of different sizes, similar to that in Zhang Xiaohua's pocket. At this time, blue and red flames were spit out under the cauldron, burning the cauldron. Above the cauldron, there were actually countless water vapor floating upwards!

Is this boiling medicine or refining elixirs?

No wonder Zhang Xiaohua was stunned.

"Is this the difference between what you said and in books?" Zhang Xiaohua, who came to her senses, turned to ask Nie Qianyu.

Nie Qianyu nodded affirmatively.

Seeing this, Nie Guzhu next to him explained: "The alchemy book says all theories, but in fact, many of them are unpracticeable. For example, the temperature of this alchemy furnace must be controlled freely, which is impossible to achieve."

Looking at the green and red flames under the cauldron, Zhang Xiaohua's spiritual sense chased after him. After a while, he nodded slightly. He heard Master Nie Gu continue: "Nephew Rich should have seen the medicine boiled in Qihuangyuan. We could not control the temperature of the cauldron before. Whenever we burned it, the herbs would turn into ashes. How could it be turned into pills? So he used the power of the water to force out the essence of the herbs, and waited for the water to dry, and the essence was also left at the bottom of the furnace."

Zhang Xiaohua suddenly realized, saying, "Boiling medicine is to boil the medicinal power of the medicinal material in water. The patient can cure the disease after taking it. The medicine residue left at the bottom of the medicinal pot. The so-called alchemy is just herbs and there is no residue left. Oh, it's not right. Nie Bofu, although the medicinal material is mostly the leaves and fruits of plants, and he doesn't want the medicinal material to be as dry as the medicine, it is also impurities after all. Are the essences left at the bottom of the furnace all the essences?"

Master Nie Gu pointed to the water vapor and said, "A lot of impurities were boiled with the water vapor, and there were very few impurities left."

In his spiritual consciousness, Zhang Xiaohua could feel the vitality of the grass and trees in the water vapor on the cauldron. This was not an impurity, it was clearly the main ingredient of the elixir. At this time, Zhang Xiaohua understood why Nie Qianyu said that the fasting pill they refined in Huichun Valley could only control one to two days of hunger. It turned out that the essence in the elixir was decocted by the method of decoction.

Zhang Xiaohua was speechless and murmured: "But, does the essence of herbs also have to run away with the water vapor?"

Master Nie Gu replied awkwardly: "This is inevitable. If you don't need to boil water, you can get nothing. If you boil water, you can get some."

At this time, Nie Qianyu said, "Brother Ren, aren't you curious about the flames that can be found under this cauldron without drying firewood?"

Zhang Xiaohua immediately looked surprised and said, "Nie Xiaoyuer, if you don't say it, I really don't care. Tell me where the fire comes from?"

Nie Qianyu also looked proud and said, "Brother Ren doesn't know that there are many passages under this valley that directly lead to the underground earth fire. The flames of my elixir refining in the spring valley are used directly through this passage."

"That's it." Zhang Xiaohua smiled and said, "Then, is this the reason why the cauldron is not easy to control the temperature?"

Master Nie Gu nodded and said, "It's true, you don't need this earth fire. The cost of ordinary flames is too high. Although Huichun Valley is rich, you can't ignore the increase in revenue and reduce expenditure."
