Chapter 451

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

Valley Master Nie smiled and said, "Nephew Ren is really attentive. The temperature in this season is exactly the same as 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 and somewhat understood. She said, "Is the temperature inside the valley not the same as outside the valley?"

"It's really like that. This valley is like spring all year round and the temperature is the same all year round. Otherwise, why would my Rejuvenation Valley be named 'Rejuvenation'?" Nie Qianyu said with a smile.

The three people continued to move forward. Valley Master Nie introduced, "This inner valley is quite large. It's more than ten miles in all directions. There are countless rare herbs planted in it. Three to five miles to the left of the valley entrance is a place that the disciples of the valley often go to. Further in is some primitive jungle where some birds and beasts live. Oh, the mountain villa's four odd beasts were found there."

Zhang Xiaohua nodded. She had already used her divine sense to scan that place. The inside was overgrown with lush vegetation and there were many wild birds and beasts. It seemed that it was also a rare place.

Valley Master Nie pointed to the boundless medicinal field in front of them and said, "This is the core of my Rejuvenation Valley. There are all kinds of herbs planted here. Because the inner valley is like spring all year round, my Rejuvenation Valley's herbs are world-famous. Of course, it is also these herbs that have created the reputation of my Rejuvenation Valley's alchemy."

Speaking of this, Valley Master Nie's face was full of pride.

Zhang Xiaohua nodded. She had stayed in Rejuvenation Valley for so long, of course, she knew its position in Jianghu. In the past, when Ou Yan of Huan Xi Mountain Villa encountered a problem with herbs, didn't she also come to Rejuvenation Valley for help?

However, Rejuvenation Valley's alchemy area was between the mountain walls of the inner valley. Her divine sense couldn't penetrate deep and she didn't know the contents. Looking at Valley Master Nie's appearance, he should be very powerful.

Then, Zhang Xiaohua pointed to the mountain wall on the right and said with a smile, "Uncle Nie, I see many disciples going in and out of the mountain wall on the left. It must be where our Rejuvenation Valley's alchemy area is. But here?

What's the use of silence? "

Valley Master Nie looked at the stone wall on the right and then looked at Zhang Xiaohua. He said in a serious tone, "Nephew Ren, you are not an outsider so there is no harm in telling you. The people who live in the stone wall on the left are all the previous generations of Rejuvenation Valley's experts. They are now old and have long stopped caring about affairs. They are living out their remaining years in this place that is like spring all year round."

"I see."

Zhang Xiaohua nodded thoughtfully. In fact, he had already seen it clearly when he was scanning with his Spiritual Sense, but he was not sure.

Although Rejuvenation Valley wasn't a great sect, it still had a history of a thousand years. It didn't make sense to say that there wasn't an expert overseeing the valley.

However, Zhang Xiaohua immediately thought of the Misty School. The Misty School was a large sect with immortal inheritance. No matter what, they should have some foundation. Where were the experts of the previous generation?

Why was it that even though the Ethereal Sect had been annihilated, there wasn't a single person standing up for them?

It was really strange!

"Then, Uncle Nie, how many of our Rejuvenation Valley's seniors are still living in the valley?"

Zhang Xiaohua asked casually.

"This …" Valley Master Nie was a little embarrassed. He looked at Nie Qianyu and said, "Nephew Ren, you are not an outsider, but this is our Rejuvenation Valley's secret …"

Zhang Xiaohua suddenly understood and said, "Uncle Nie, if it's a secret, it's better not to say it."

"Hehe, actually, the climate in the valley is very pleasant. Moreover, in my Rejuvenation Valley, I don't dare to say anything else, but there are many herbs that can prolong one's life and nourish one's body. Therefore, hehe, there really are many seniors living here."

"In addition," Valley Master Nie said mysteriously, "Nephew Ren, don't look at my ordinary martial arts. Rejuvenation Valley also has its own unique skills. In the past, there were many top ranked experts in the pugilistic world in our Rejuvenation Valley."

He looked like he was showing off.

Zhang Xiaohua was speechless.

Nie Qianyu pointed to the herb garden not far in front and said, "Brother Ren, look, this is the main ingredient for refining the Blood Replenishing Pill. If it is a year old, it is not very useful. The Blood Replenishing Pill uses Gastrodia Tuber that is more than five years old. The Rejuvenation Valley's climate is stable and is most conducive to the growth of herbs. Moreover, for some reason, the herbs in the inner valley grow better than those in the outer valley.

Zhang Xiaohua walked closer and slightly released her divine sense. Of course, the Qi of Heaven and Earth in the inner valley was more than three times that of the outer valley. How could these herbs not grow well?

Looking at the terrain of the inner valley and the dense herbs, it was inevitable that the Qi of Heaven and Earth could gather here.

"That's right," Zhang Xiaohua suddenly realized and said, "Valley Master Nie, why is the climate in the inner valley like this?"

Valley Master Nie smiled but did not speak. Nie Qianyu said, "When Brother Ren enters this stone wall and sees how Rejuvenation Valley refine pills, you will naturally know."

Below the stone wall on the left, there were dozens of small caves. Disciples of Rejuvenation Valley entered and exited from time to time. When they saw the Valley Master, they all bowed and saluted.

Walking closer, Valley Master Nie pointed at these caves and said with a smile, "Nephew Ren, this is where Rejuvenation Valley refine pills. Why don't you guess why there are so many caves?"

Zhang Xiaohua was startled. She thought for a moment and shook her head, saying, "I don't know that different caves have different functions."

Nie Qianyu said, "Brother Ren, don't think too much. Just a simple guess and you will know."

Zhang Xiaohua was about to shake her head when her mind lit up. She said with a smile, "Could it be that different pills are in different caves?"

Nie Qianyu immediately applauded and said, "Like I said, Big Brother Ren is thinking too much. The way of alchemy is not as magical as what is written in the books. Big Brother Ren will definitely be able to guess it from a simple way of thinking."

"Not as magical as it is written in the books?"

Zhang Xiaohua was startled and a question arose in her heart. Could it be that Rejuvenation Valley's pill refining techniques were different from what was written in the books?

When Valley Master Nie and Nie Qianyu led Zhang Xiaohua into a random cave, Zhang Xiaohua was immediately stunned by the scene in front of her. Yes, that's right. She stood there blankly and did not move at all!

Valley Master Nie and Nie Qianyu did not find it strange when they saw this. They just quietly waited for her to react.

After a long while, Zhang Xiaohua touched her nose and asked with a wry smile, "Uncle Nie, this is the place you said to refine pills?"

Then she said to Nie Qianyu, "This is the normal part of refining pills that you said?"

Nie Qianyu said with a smile, "That's right. Refining pills is just like this. However, are you shocked by Rejuvenation Valley's generosity?"

"That's right, that's right." Zhang Xiaohua looked around carefully. She even released her divine sense and looked around again and again.

Everyone, what do you think is the scene that Zhang Xiaohua saw? It actually made the successor of the Immortal Dao, Zhang Xiaohua, who had truly refined the Fasting Pill, so surprised?

She saw that this was a rather large cave. It was slender and long. On the mountain wall in front of Zhang Xiaohua, there were more than ten grooves. On each groove were cauldrons of different sizes, similar to the cauldrons in Zhang Xiaohua's purse. At this moment, a green-red flame was spitting out from under the cauldrons and was burning the cauldrons. Above the cauldrons, there was actually … actually countless amounts of water vapor floating up!

This, was this brewing medicine or refining pills?

It was no wonder that Zhang Xiaohua was dumbfounded.

"This is the difference you said to be from the books?" Zhang Xiaohua, who had regained her senses, turned to ask Nie Qianyu.

Nie Qianyu nodded affirmatively.

When Valley Master Nie saw this, he explained, "What is written in the alchemy books are all theories. In fact, many of them cannot be practiced.

For example, it is impossible to freely control the temperature of the cauldrons. "

Looking at the green-red flame under the cauldrons, Zhang Xiaohua's divine sense chased after it. After a while, she nodded slightly. Valley Master Nie continued, "Nephew Ren should have seen Qi Huang Courtyard's brewing medicine. Previously, we were also unable to control the temperature of the cauldrons. When it was casually burned, the medicinal herbs would turn into ashes. How could it be refined into pills?

Therefore, with the help of the water, the essence of the medicinal herbs would be forced out. When the water dried up, the essence would also be left at the bottom of the cauldrons. "

Zhang Xiaohua suddenly understood and said, "Brewing medicine is to boil the medicinal power of the medicinal herbs in water. When the patient takes it, the patient will be cured. What is left at the bottom of the cauldron is the medicinal dregs. This so-called refining pill is only the medicinal herbs. There is no residue left. Oh, that's not right, Uncle Nie. Although the medicinal herbs are mostly the leaves and fruits of plants and are not as dry as medicinal herbs, there are still impurities. Is the essence left at the bottom of the cauldron the essence essence?"

Valley Master Nie pointed to the water vapor and said, "A lot of impurities have been boiled out with the water vapor. There are very few impurities left."

In her divine sense, Zhang Xiaohua could feel the vitality of the essence of the plants in the water vapor above the cauldrons. How could this be impurities? It was clearly the main component of the pill. At this time, Zhang Xiaohua understood why Nie Qianyu said that the Rejuvenation Valley's Fasting Pill could only cure hunger for one or two days. It turned out that the essence of the sealwort had been boiled away by the method of brewing medicine.

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

Valley Master Nie replied awkwardly, "This is inevitable. If you don't boil it in water, you won't get anything. If you boil it in water, you can get some."

At this time, Nie Qianyu said, "Big Brother Ren, don't you feel curious about the fire under the cauldron without using dry firewood?"

Zhang Xiaohua immediately looked surprised and said, "Little Fishy Nie, if you didn't mention it, I really wouldn't have cared. Now, tell me, where does this fire come from?"

Nie Qianyu also looked proud and said, "Big Brother Ren doesn't know that there are many passages under this valley that lead directly to the underground earth fire. The flames that my Rejuvenation Valley uses to refine pills use the earth fire directly through these passages."

"So it's like this," Zhang Xiaohua said with a smile, "Then, is this the reason why the cauldron's temperature is not easy to control?"

Valley Master Nie nodded and said, "Really, we can't use this earth fire. The cost of ordinary flames is too high. Although Rejuvenation Valley is rich, we can't not consider increasing our income and reducing our expenditure."

"Ah!!" Zhang Xiaohua was stunned.
