However, Ye Yu thought of himself at this time.

Do you have to spend tens of thousands of years or even hundreds of thousands of years here before you go out?

However, the beauty in white was captured by the crown prince of cracked heaven.

In addition, the Terran is in danger and needs strong support.

Ye Yu is not reconciled to the two goals in his heart. Like these people, he has practiced here for ten thousand years, even more than ten thousand years.

It's too long.

It was too long for Ye Yu to wait.

However, he had no clue at this time, so he had to practice for a while.

Therefore, next, Gu Tianlang and Ye Yu both found a remote place in this boundless cave, sat cross legged and began to practice.

In this cave, the aura is very strong.

Ye Yu found that it was even richer than the aura in the temple.

It seems that there are some soul gathering arrays in the cave where boundless son is located. Otherwise, it can't be so rich in aura.

Ye Yu knew that if it weren't for Gu Tianlang's relationship, I'm afraid he wouldn't be qualified to practice in this elder's cave.

Next, Ye Yu went directly into deep practice.

He began to understand the "secret of killing the world by gods and demons". This set of skills is extremely mysterious and terrible. It is a complete version of the spirit refining body in the demon prison. In the inheritance information, Ye Yu learned that this set of skills is also known as the "nine reincarnation and death skills".

Cultivation is extremely harsh. There are nine turns in total. Each time you experience life and death, you can change once.

But ye Yu wondered what it was like to experience life and death.

Is it death first and then resurrection by means of rebellion?

Obviously unlikely.

Ye Yu guessed that the so-called transformation of life and death should be the so-called breaking and then standing.

Nine times to break and then stand. Life is better than death. It's absolutely terrible and difficult to think about it.

However, this "secret of killing the world by gods and demons" is an extremely terrible skill. I'm afraid only by practicing this level of skill can we really win the rank of the strongest.

Therefore, Ye Yu does not regret his choice.

In the next few days, Ye Yu practiced silently in the cave. His accomplishments were not small.

However, on this day, there was an angry roar outside the cave.

"Gu Tianlang, and the boy who dares to play with me, come out. I know you must be hiding here." that was the voice of the mysterious old man. He guessed that Gu Tianlang and Ye Yu would come to the million copper mountain.

In the cave, boundless son still sat there, his face ancient well without waves, his eyes slightly closed, as if he were like a rock, regardless of anything.

Gu Tianlang opened his eyes. He looked at Ye Yu standing up and said, "brother ye, don't worry about the mysterious demon old man. Even though he is strong and arrogant, he doesn't dare to be presumptuous in this million copper mountain."

"I understand."

Ye Yu nodded. He knew that he was probably the weakest existence in the human race, and no one could resist it.

"It's really a bit tricky for you to annoy this man." suddenly, the boundless son in the center of the cave made a noise, and his eyes were still closed, but he said aloud: "but don't worry, the mysterious demon old man, no matter how cruel and unscrupulous he is, he will never dare to run wild in this million copper mountain. If he dares, the consequences will be absolutely miserable."

"Boom"

However, at the moment when the boundless voice fell, Gu Tianlang and Ye Yu suddenly heard a terrible roar outside.

Obviously, it may be that the arrogant behavior of the mysterious demon old man provoked some people to fight with a powerful existence.
