"You guessed right." The mysterious old man said with a smile: "as long as you practice the secret code of time and space to the highest level, you can reverse time and space, and live forever."

"The secret code of time and space has such means against heaven!" Mu Yu was stunned, then shook his head and said, "but why can't I do it?"

The mysterious old man said with a smile, "that's because your secret Dictionary of time and space is incomplete."

Incomplete?

Mu Yu once again fell into meditation. He remembered that after the wuliangzong library combined two volumes of space-time secret scriptures, the system told him that this was the complete version of space-time secret scriptures.

At the moment, the old man told him that his time and space secret Scripture was not a complete version.

Isn't the two contradictory?

The mysterious old man said again: "in fact, what I said is not completely right. Your secret Dictionary of time and space is actually complete."

Mu Yu's language is stagnant. How can the old man talk like this and like that all of a sudden? People can't understand him.

"Is the secret code of time and space that I practice complete or incomplete?"

Mu Yu's eyes were white and speechless.

"Don't worry, just listen to me."

The mysterious old man coughed and said slowly, "the law of time and space is the most profound and mysterious law in the whole world. Although I think I have different talents, I can't understand any of them."

"The reason why I am able to write the secret Dictionary of time and space is that I accidentally got a mysterious crystal stone in the hanging cliff, which seems ordinary but contains a profound road."

"After more than ten years of research, I finally found a very mysterious power, which is the power of time and space. Since then, I have been obsessed with the study of this mysterious crystal, and in a twinkling of an eye, it has been a thousand years."

Mu Yu suddenly said: "in this way, the reason why you can write the secret code of time and space is because of this mysterious crystal stone."

"That's right." The mysterious old man said, "I have learned a lot about the power of time and space through my research in the past 1000 years, so I wrote the secret code of time and space, so what you are practicing is the secret code of time and space I left behind at that time."

"And why did you just say that the secret Scripture of time and space I practiced was incomplete?"

Mu Yu asked again.

"That's because, at that time, I only understood the space-time power of some mysterious crystal stones, so the space-time secret Scripture I wrote was certainly incomplete."

"Many years later, I learned a lot about the power of time and space from the mysterious crystal. I didn't write down this part of the power."

When the mysterious old man said this, Mu Yu finally understood everything.

No wonder he can't live forever by practicing the law of time and space.

"By the way, you haven't answered me. Where did you learn the secret code of time and space?"

The mysterious old man asked again.

"Oh." Mu Yu came back to his senses and said quickly, "I am a disciple of wuliangzong, and the secret Scripture of time and space is one of the nine secret scriptures of wuliangzong. It has been lost for tens of thousands of years, and the younger generation also got it by accident and got it by chance."

"So you are a disciple of wuliangzong."

The mysterious old man said, "wuliangzong was founded by my apprentice who didn't become a tool. So you are my apprentice."

The corners of Mu Yu's mouth twitched violently. At that time, the three supreme artistic conceptions he realized under the white jade wall came from the founder of wuliangzong.

In the old man's words, such a gorgeous and arrogant existence is just a useless apprentice.
