Chapter 763: Instructing Nie Changfeng

"This is mine."

Nie Bufan looked up at Nie Changfeng who was in shock, snatched the Bu Tian Dan and swallowed it.

The Bu Tian Dan is a very precious elixir that can repair congenital deficiencies and can comprehensively improve a person's strength.

Take Nie Bufan for example. The first flame that appeared when his spirit body was opened was the Nine Flames True Fire, but due to congenital deficiencies, the Nine Flames True Fire degenerated and dropped to the level of the Six Flames True Fire.

With this Bu Tian Dan, he can repair the congenital deficiencies and promote the flame to the level of the Nine Flames True Fire.

However, ordinary Bu Tian Dan can't achieve such an effect, but the Seven Tribulations Bu Tian Dan can definitely do it.

So, he was so excited

"You kid is too much. Even if you want to eat it, you have to wait until I study it before eating it, you prodigal son."

Nie Changfeng cursed angrily. He didn't feel sorry for Nie Bufan eating this pill, but was angry that he ate it too quickly.

After all, he also knew Nie Bufan's situation. For the sake of his son, he would ask Yun Yi for the pill even if he had to lose face.

But, you don't need this moment, it's not too late to eat it after I finish my research.

"Brother Yun, I'm also anxious. I'll refine the pill first and apologize to you later."

Nie Bufan knew that what he did was a bit unfair. After all, this pill was made by Yun Yi, and the value of the Seven Tribulations Pill was also very high.

But he was too eager for this day. Because of the flame, his alchemy encountered a bottleneck and it was difficult to break through.

With this pill, he can go further.

As for the favor of this pill, he will make it up to Yun Yi in the future, even if he lets him go through fire and water.

"It's okay. I can make this pill easily. Giving you one is nothing. You should refine the medicinal power first to avoid wasting it."

Yun Yi waved his hand and didn't take this pill seriously at all. As he said, the Seven Tribulations Pill was nothing to him at this time.

What's more, this medicinal material was provided by others.

"Okay." Nie Bufan responded and immediately walked to the side and sat cross-legged to refine the medicinal power of the Bu Tian Pill.

"Yun Yi, your performance greatly exceeded my expectations. Although I am your nominal master now, I dare not take the title of Master. How about this, you can call me Big Brother in private, and still call me Master and Disciple in public, what do you think? After all, your attainments in alchemy are far beyond mine. I am afraid I can't teach you anything. Instead, I have a few questions here and want to ask you."

Nie Changfeng blushed a little. Originally, he accepted Yun Yi just to recruit a genius for Tianyun Pavilion, and he didn't plan to teach him the alchemy skills.

After all, alchemy requires not only talent but also time. Nie Bufan alone is already a headache for him, and he has no time to take care of another one.

Now he has to ask Yun Yi for advice, which is really unexpected for him.

"Big brother, you are too polite. I don't dare to ask for advice, but it is okay to exchange and verify with each other."

Yun Yi nodded. He really didn't think about becoming a disciple, because he had his own ideas about cultivation, and he had Heifeng by his side, so he didn't need others to intervene.

Nie Changfeng's proposal was just what he wanted.

"Haha, okay, Yun Yi, I want to ask, when you were refining the Bu Tian Dan, how did you mix the Qi Yang grass and the Ju Yin water?"

Nie Changfeng asked straight to the point. This matter has been bothering him for a long time.

"Qiyang grass and Juyin water are opposites, one is yang and the other is yin. Therefore, they cannot be extracted too pure. The purer they are, the less likely they are to fuse. Leaving some impurities will help them fuse. When the pill is formed, remove them with fierce fire."

"Leave impurities? But don't impurities hinder the fusion of drugs?"

"Nothing is absolute in the world. You must know that every pill will undergo many changes during the refining process due to the different years of the medicinal materials and the different control of the fire. A slight difference can lead to a huge loss. Therefore, during the refining process, we need to vary according to the time and situation, pay close attention, and adjust at any time. Don't be stereotyped. After all, there are no two identical pills in the world, and there is no identical refining method."

"I've learned from you."

...

The two of them talked back and forth. Nie Changfeng asked his questions one by one, and Yun Yi answered fluently with the help of the Hunyuan Dan Sutra.

As time went by, the two chatted more deeply and happily. This was not only an improvement for Nie Changfeng, but also a sublimation for Yun Yi, which made him have a new understanding and understanding of the Hunyuan Dan Jing.

If he were asked to refine the Bu Tian Dan again now, he should be able to do better.

Boom!

Just as the two were chatting happily, a flame shot up into the sky, and the powerful power spread all around, which was extremely terrifying.

Yun Yi knew that Nie Bufan's innate deficiency was made up, and the flame also went one step further and advanced to the level of Jiumei True Fire.

"Haha, I finally broke through."

Nie Bufan shouted excitedly. He had waited for this day for too long and looked forward to it for too long. Once he got it, he was ecstatic.

But he knew that all of this was thanks to Yun Yi, so he immediately suppressed his excitement and came to Yun Yi.

"Brother Yun..."

"You little brat, Yun Yi calls me big brother, and you call him brother, are you trying to rebel? Hurry up and call him uncle."

Nie Changfeng patted Nie Bufan on the head and said.

"Uncle?"

Nie Bufan was stunned. How could he have been reduced to the level of his nephew in the blink of an eye?

"Why, it can't be done?"

Nie Changfeng said with a cold face, as long as Nie Bufan dared to say no, he would be ruthlessly tortured.

"Brother, let's each call him his own to save everyone the trouble."

Yun Yi scratched his head, how could he really let Nie Bufan call him uncle? No matter what, Nie Bufan had saved him, and his cultivation level was much higher than his own, so it was enough for them to be equals.

"Well, anyway, you have to thank Yun Yi properly today. If he needs help in the future, if you dare to say no, I will beat you to death."

Nie Changfeng said that Yun Yi's appearance could be said to have helped Nie Bufan change his destiny. Moreover, he was also very helpful to himself. At the very least, he could improve the elixir he refined by one elixir pattern.

This is a very terrifying improvement. If he had done his own research, he might not have reached the current level in decades.

"Father, don't worry. Yun Yi is a gift to me. If it comes to the point you said, I will kill myself without you taking action."

Nie Bufan said loudly and authentically.

"By the way, Yun Yi, does Lin Wushuang need my help to solve this problem?"

Nie Bufan suddenly remembered this matter and asked.

"No, he doesn't need you to take action yet, but now I need to quickly improve my strength. Is there any way?"

Yun Yidao said that although Lin Wushuang was powerful, he was not powerful enough to scare him, and his presence would only make him more motivated.
