Chapter 762 Seven Tribulations Heaven-Repairing Pill

Nie Bufan also knows how to make pills, and his level is not low. He has also been taught by Nie Changfeng, which makes him stand out among his peers, and his alchemy skills are unmatched.

In his opinion, alchemy must be carried out according to specific steps, only in this way can a more perfect pill be made.

But Yun Yi's method is to refine and extract all the medicinal materials at the same time. How can it be perfect?

So, in his opinion, Yun Yi is just fooling around.

Nie Changfeng is different. His attainments in alchemy have reached the level of perfection.

At the beginning, he also thought that Yun Yi was fooling around.

But after seeing Yun Yi's flame and his control of the flame, his impression changed. He stared at Yun Yi with a pair of eyes, afraid of missing any details.

Moreover, as Yun Yi continued to refine the pill, Nie Changfeng's eyes became brighter and brighter, and he looked like a student seeing his teacher teaching him in person.

Yun Yi ignored them and put all his energy into refining the Bu Tian Dan. Under Yun Yi's control, hundreds of medicinal materials were like little elves flying in the flames, and a large amount of impurities were quickly removed.

Soon he entered the second step, fusion.

This was Yun Yi's second time refining an imperial-level elixir, and his cultivation had reached the realm of the sixth-level spirit king, and his soul power had been further improved and tempered.

Although he failed to break through the imperial level, he was far superior to the general ninth-level spirit king, making it easier to refine imperial-level elixirs.

So when fusion was performed, Yun Yi used a difficult alchemy technique to use a more violent flame to promote the perfect fusion of the elixir.

The time of the whole process was also greatly shortened. It only took one minute to completely complete the fusion, condense together, and form a elixir the size of a longan.

From the beginning to now, the whole process of refining the Bu Tian Dan took only three minutes, which was two-thirds shorter than the first time he refined the Qian Yuan Hua Xue Dan, and it was even more perfect.

The progress was so great that Heifeng was amazed.

All of this was also imprinted in Nie Changfeng's eyes. He didn't expect that the elixir could be refined in this way. Not only was the speed fast, but every step was so perfect that even he couldn't find any faults.

"The elixir is done!"

Yun Yi roared, and the red lotus fire suddenly jumped up, wrapped the elixir, and calcined it twice, allowing it to fuse again during the process of elixir formation, and removed the excess impurities, and then the flame moved, dragging it into the air.

The next moment, the originally clear sky became cloudy and lightning surged.

"What a strong elixir tribulation."

Feeling the calamity cloud in the sky, based on Nie Changfeng's experience, this must contain at least the fifth level of elixir tribulation, which is many times stronger than the Bu Tian Dan he refined.

"Come on."

Yun Yi immediately blocked his breath, and Nie Changfeng and Nie Bufan did the same. Then, an elixir tribulation descended and hit the Bu Tian Dan.

The Bu Tian Dan endured this pill tribulation without moving at all, and a mysterious pill pattern appeared on the Bu Tian Dan.

"Father, how many pill tribulations can this Bu Tian Dan withstand?"

Nie Bufan couldn't help but ask. In theory, alchemists like them can determine how many pill tribulations the pill can withstand through their pill refining techniques.

Even if there are some discrepancies, they will only fluctuate around one, and will not deviate too much.

But Yun Yi's pill refining technique was unheard of by him, and it was completely beyond his cognition. With his experience, he couldn't determine how many pill tribulations this Bu Tian Dan could withstand, and he couldn't even guess roughly.

"In my opinion, at least five."

Nie Changfeng was also unsure. The reason why he could say this result was because of his perception of the pill tribulation. He didn't know whether it was true or not.

Recalling Yun Yi's pill refining process, he felt ashamed of himself, and he didn't expect that pills could be made in this way.

Suddenly, he felt that he had lived like a dog for so many years, and he couldn't even compare to a sixth-level spirit king.

Boom!

While they were talking, the second pill tribulation also descended. Like the first one, it did not cause any waves at all.

Boom!

Boom!

Boom!

Then there were three more. Counting the previous two heavenly tribulations, there were a total of five, which had already reached Nie Changfeng's expectations.

But the tribulation clouds in the sky still had no intention of dispersing, and Yun Yi had no intention of stopping, still looking at the Bu Tian Dan with confidence.

The method Yun Yi used this time was also very advanced in the Hunyuan Dan Sutra, using the most violent flame to stimulate the most perfect fusion.

This method not only requires a strong soul and fire control method, but also a very advanced flame. All three are indispensable.

And Yun Yi just had all three, the soul of the peak of the ninth-level spirit king, the powerful Hunyuan fire control technique, and the red lotus karma fire of the king of all fires, all of which were extremely powerful.

Therefore, Yun Yi has enough confidence in the Bu Tian Dan this time. Six tribulations are not its limit at all.

Boom!

The sixth heavenly tribulation descended and hit the Bu Tian Dan heavily. This time it was not as calm as before. It was directly hit and shook.

But it still did not make the Bu Tian Dan retreat. After absorbing this heavenly tribulation, six dan patterns appeared on the Bu Tian Dan.

The six dan patterns intertwined together, blooming with a faint light, and vaguely saw a colorful halo, which was very charming.

"Is it almost done?"

Nie Changfeng's heart was lifted up. He now completely believed Yun Yi's words. You know, this Bu Tian Dan is a very difficult pill to refine.

Yun Yi can refine it to the level of six tribulations, so Qian Yuan Hua Xue Dan is even more of a piece of cake.

"It's not enough, try again."

Yun Yi didn't take Nie Changfeng's reminder seriously at all. Moreover, in his opinion, there is no difficult pill to refine.

The reason why they feel difficult is that they don't have the right method.

Moreover, he is full of confidence in the Bu Tian Dan he refined. Six tribulations is still not the limit of Bu Tian Dan, so he roared to the sky.

The tribulation cloud in the sky seemed to feel Yun Yi's disregard, and immediately became angry, and another pill tribulation descended.

The lightning as thick as an arm instantly fell on the Bu Tian Dan, smashing it directly into the ground.

This time, the lightning lasted for a quarter of an hour before it finally dissipated. Nie Changfeng and Nie Bufan were even more nervous than Yun Yi, and ran over at the first time.

Looking down, he saw the round Pill of Heaven-Repairing in the hole on the ground, with seven rows of pill patterns with colorful halos on it.

"Seven Tribulations Pill of Heaven-Repairing, my goodness, this is going to defy the heavens."

Even though Nie Changfeng had been mentally prepared, he was still shocked when he saw the pill.

This is the Seven Tribulations Pill of Heaven-Repairing. Since Dan Chenzi disappeared, the Seven Tribulations Pill of Heaven-Repairing has not appeared in Xuanyu for a long time.

Not to mention the Seven Tribulations Pill of Heaven-Repairing.
