Yang Chen couldn't figure it out. It should be true that there was no mistake in any link, but what exactly was going on.

"Where is it..." Yang Chen worked hard to refine the elixir accurately while searching for which part of himself went wrong.

After all, even he couldn't guarantee that he would not make any mistakes after refining it at extremely high density.

Soon, Yang Chen suddenly thought of something: "Is it a problem with the heat when the last ingredient was put in?"

When he thought of this, Yang Chen trembled all over.

This is probably a point that will be difficult for him to solve.

It wasn't that there was something wrong with the steps he put in, but that the control of the heat was very difficult and required to be very precise. He was just a tiny bit off.

I originally thought there would be no problem, but it seems that this is the reason why the liquid cannot solidify into a pill state.

This made Yang Chen anxious for a while.

If he continues to be unable to get out of this cycle, it can basically be declared that his alchemy has failed.

How could Yang Chen accept such complicated materials? He was from all over the world. He spent a lot of money on the materials he obtained from the Black Demon Clan's material warehouse, plus the materials taken from the mausoleum, and then he managed to get it together. A batch of materials for the Nine Nether Elixir was prepared.

If the refining fails this time and he tries to get it together next time, he may not have this chance in who knows what year, or even in his lifetime.

Is he willing to do this?

No, never.

If he really gives up this once-in-a-lifetime opportunity, he will not get a second chance. This is the highest honor for an alchemist, even if he is the only one to witness it, he will still fight for it.

Just when Yang Chen had this thought.

He suddenly entered an extremely mysterious realm.

He felt that everything around him became quiet, the sound of wind and dust all disappeared. All that was left in his world was the alchemy furnace in front of him.

Unlike usual, the fire burned slower and the liquid flowed slower.

It was precisely because of this that Yang Chen became calmer.

He could actually see the flow of liquid clearly, which meant that he could analyze the state of the liquid based on its flow and condense it into a solid at will.

This is an ability that all skillful alchemists possess.

The same is true for Yang Chen.

At this moment, Yang Chen was even more surprised: "It's such a mysterious realm. Although I don't know what this realm is like, I can easily solidify elixirs from ashes in this realm. Of course, this Nine Nether Immortal Pill Refining I'm afraid it's a little difficult and tricky to make. However, in this state, I should have the greatest possibility of refining the Nine Nether Immortal Pill. If I miss this opportunity, I will not have the ability to refine the Nine Nether Immortal Pill for the second time. The possibility of the Nether Immortal Pill."

There can be no further delay.

Yang Chen did what he said, and in this very delicate state, he took the time to solidify the Nine Nether Immortal Pill.

In this state, he is calmer and more skilled. It is precisely because of this that the liquid state gradually becomes the prototype of the elixir state.

Yang Chen was extremely happy. This state was indeed useful. If this continued, he might be able to refine this elixir.

…

Ye Kun was watching Yang Chen's every move while refining the elixir. He didn't make a sound. If he hadn't actually seen him standing behind Yang Chen and just observed his breath, he wouldn't have noticed that he existed here.

Ye Kun's observation is extremely keen, and it is precisely because of this that he is extremely curious.

"Strange thing... When I looked at little friend Yang Chen just now, I just felt that his aura was very chaotic. Now when I look at it again, I just feel that little friend Yang Chen's aura is even and orderly. If he does things in this state, he should be extremely meticulous and not make any mistakes. ." Ye Kun said to himself.

While thinking this, Ye Kun suddenly felt some changes in the sky.

"What is this?" Ye Kun narrowed his eyes.

Soon, he was shocked.

"Thunder Tribulation, Thunder Tribulation again!" After Ye Kun said this, he showed a wry smile. It's not surprising that he said it again and again, because after getting to know Yang Chen, this was indeed not the first time he had seen Thunder Tribulation.

The last time Yang Chen's soul caused a thunderstorm, although he was not around, he could clearly sense it from a distance.

But the power of this thunder tribulation does not seem to be as powerful as that time.

"It's too bad..." Ye Kun made a certain judgment.

Yang Chen may or may not be able to withstand this thunderstorm.

To be precise, this is not a thunder calamity that the True God Stage can handle.

At this time, Yang Chen did not sense the thunder disaster coming. Firstly, he was not as powerful as Ye Kun, and secondly, he did not put his energy into it.

It's not too late for him to be happy now. After all, being able to refine a Nine Nether Immortal Pill is not a simple and easy task. Even at his level, he almost failed. If he hadn't finally entered that wonderful state, I'm afraid he would have become the master now. Dan or not is still unknown.

Yes, the Nine Nether Immortal Pill has been refined.

In the current alchemy furnace, there is a glowing elixir lying. The most noticeable thing about this elixir is the lines around the elixir. These lines are layer after layer, one after another. Count them one by one, at least there are. There are hundreds of them.

It feels like these lines are more like announcing death, and the elixir's body also exudes a ghostly aura, as if telling others that it is dangerous.

Yang Chen couldn't help but touch and play with it. After all, this was his greatest masterpiece now.

But just as he stretched out his hand, he sensed the terrifying power coming from the sky. This terrifying power had not yet come down, and it was already oppressing him and making it difficult to breathe.

"Little friend Yang Chen, if you don't deal with it anymore, I'm afraid it will be bad." Ye Kun reminded. "This is your thunder tribulation. I will leave first. You must go all out. This thunder tribulation may not be good for you."

Yang Chen also thought so. He didn't know it at first, but now when he saw the thunder and lightning power gathered in the sky thunder pool, he realized that Ye Kun was not joking.

That's right. When he refined the Shenxiu Good Fortune Pill, the lightning disaster almost killed him.

The thunder tribulation of elixirs does not depend on your cultivation level. The higher your cultivation level, the thunder tribulation will be strengthened immediately, which is different from the thunder tribulation of advanced cultivation.

It is impossible to refine this heaven-defying elixir without facing certain punishment.

His Shenxiu Good Fortune Pill can barely be regarded as a mid-level divine product. It may be at the high level, but compared with the Nine Nether Immortal Pill, it is still more than one level behind.

So the calamity caused by pills of this level is a little more terrifying, which is understandable...
