There were originally many small centipede-shaped reliefs on the walls on both sides, and there were also many small centipedes on the murals as decorations. At this moment, they actually twisted and crawled towards Mu Chen off the wall.

Mu Chen thought that after these two days of training, his courage had become very strong, but he still felt scared when he saw these centipedes.

He once thought that on a cruise ship was the fastest time he had ever run in his life, but he didn't expect that he would break the records frequently in the past two days. For example, now, when he thinks of Lin Shuang's miserable situation, he is full of strength and runs like a gust of wind. If he were placed in the Olympics, he might even win an award.

The little centipedes falling from the walls on both sides caused him great trouble. He had to pay attention to both sides while running forward. The passage was very narrow. Fortunately, these centipedes did not have much bounce ability, otherwise Mu Chen would have been instantly lost in minutes.

Even so, he ran away in a very embarrassing manner. Suddenly, a centipede fell from the top and rushed straight to Mu Chen's face. He hurriedly hid to the side, but he didn't know what mechanism he encountered. A door suddenly appeared in the passage. Mu Chen didn't react at all, and could not restrain his strength and fell into the door. After he fell in, the stone door immediately closed without leaving any gaps.

Mu Chen got up from the ground and instinctively rushed to the door, wanting to see if there was any mechanism that could be opened. But he went back and forth, touching the wall all over, but still found nothing.

He had to change his mind and go to see other places. The space was very small, only a few dozen square meters. There was a small box on the ground in the middle, except for that.

Two hours later, Mu Chen lay in despair on the ground, feeling a little desperate. I don’t know if it wasn’t talented or if it couldn’t be opened from the inside. During these two hours, he used all the methods he could think of and all the tools he could use, but he still couldn’t open the door.

Finally, he had to turn his gaze to the small box. If there was anything else in this space that Mu Chen had not touched, then there was only a small area under this box. He always felt that there was a box here that was very strange, and he was afraid of having a mechanism, so he didn't dare to touch it rashly.

Carefully open the box, which contained a letter and two books, and some things for ignition.

Mu Chen was a little surprised, what combination is this?

He opened the letter first. The letter was very short, and the first line was only eight big words, "I have been waiting for a thousand years, and you will finally come now"!

Seeing this, Mu Chen shook his hand and the letter almost fell off. Could it be that this letter was written by Guo Pu? Was he waiting for him? But two hours ago, even he didn't know that he would come here. Did he have calculated everything he would have today more than a thousand years ago? If this is true, then this person's attainment in hexagram science has really reached the pinnacle and is almost a magical understanding!

But why did he wait for himself? And why did he put things here?

Mu Chen continued to look with a question mark on his head.

"You are the one who is destined to be a person, and the rise and fall of the hexagrams are all related to one body. The future of the arts is only one person. For two thousand years, the changes in the wind and clouds have come to a close, and the dust of your body has settled.

No one dares to refuse to obey the great tasks of heaven. You should do your best to do your best and never regret it even if you die. Now I will give you something to learn throughout my life and help you achieve success, which will fulfill our long-cherished wishes.

There is also a magical book called "Tongxuan", which is the hard work of the wise men of all generations. You must understand the words and sentences in your heart and never forget them! It takes two days to reach the limit, and you can read the full text. After memorizing it, you must burn it and do not keep it without leaving it!

No one knows this here, but if you come out, you will destroy yourself. My strength is limited. If you say this, be careful of everything!"

If it was just a question mark on the forehead just now, then Mu Chen is full of question marks. Is Guo Pu also a member of the hexagram? What is his long-cherished wish for the two thousand years? What does this have to do with him? And why is the book "Tongxuan" called the divine book? Is Yan'er's trip for this?

Mu Chen shook his head and stopped thinking about this. He knelt down and kowtowed three times to the box. Since the other party left all his lifelong practice here, he was his master. As for his long-cherished wish, if he had the chance to figure it out, he would do his best to help him complete it.

After performing the ceremony of apprenticeship, Mu Chen took out the book in the box, first of which was the book "Tongxuan".

After opening it, Mu Chen was stunned. The book should be written in code, and it must have a password to extract valid information to understand it. If you read it now, it would be simply nonsense and it doesn't match it at all.

I don’t know when and who wrote this book, but Mu Chen didn’t know any of the characters on it. Fortunately, Guo Pu calculated this and helped him convert the font and copy it.

Although I have been memorizing a lot since I was a child and have always thought that I have a good memory, this is the first time Mu Chen memorized this book that has nothing to do with the previous word and the next word. No wonder I have to give two days, this book is even harder than a dictionary.

What's even more frustrating is that since you need a password, it means that you must remember every line and every page clearly. If you miss a word, even if you have a password, you probably won't be able to solve it. Mu Chen felt the despair from memorizing the text for the first time in his life.

This has been wasted more than two hours, and time is tight. Mu Chen put another book in his bag without even looking at it.

For the next forty hours, Mu Chen didn't even close his eyes, nor did he have time to eat anything, and his mind was full of fragments of words. Fortunately, the equipment Yan'er bought was of good quality, the flashlight battery was very durable, and everyone had a lot of spare batteries, so that he would not have to worry about other things while endorsing.

The time here should be a timer. When two days arrive, the door immediately opened. Mu Chen sighed and burned the "Tongxuan" that had been completely imprinted in his mind. At the same time, there was also the box. After confirming that it was burned completely, he walked out.

After Mu Chen came out, the stone gate closed again, and then there was a rumbling sound, and the space behind should have collapsed.

The passage was clean, and I didn’t know where the centipedes had gone. Mu Chen identified the direction and rushed forward. Two days later, I didn’t know where the others had gone. I had already gone out? I was alone and I had encountered any mechanism poison, so I probably had to explain it here.

Walking further, there were traces of fighting on the ground, and there were some dead centipedes. But Mu Chen had never seen the body of the white centipede. I hope Mr. Qin would not have any trouble.

After walking for a while, the passage in front was blocked by a stone door. The mechanism of the stone door was obvious, right next to it. Mu Chen gently pressed it, and the mechanism started, and the stone door slowly rose.

However, before I could see the situation inside, Mu Chen felt a headache and was knocked unconscious.

Mu Chen had not closed his eyes for two days and two nights, so he simply fainted and slept beautifully. When he opened his eyes, he saw a bunch of people in front of him, Yan'er, Leng Ye and the others were all there. Everyone's faces looked ugly, especially Leng Ye, with a strange expression.

Before Mu Chen could speak, Leng Ye shouted, "Damn, buddy, you finally woke up! Oh, I fucking thought I beat you to death!"

He didn't say that, Mu Chen almost forgot that he was knocked out. "Why did you hit me?"

"Damn, we've been sleepy for two days here. Suddenly the door opened and there were footsteps. Are you nervous? My principle has always been to take action first and be prepared to control people. But who knows, why are you so weak? I didn't even exert much effort. It's logical that you can wake up in half an hour, but you've been in a coma for six hours!"

As he said that, he looked at Mu Chen with resentment, "To be honest, if you don't wake up again, Yan'er will probably kill me!"

Mu Chen moved his mind and didn't know how to explain it. Since that's the case, let's throw the blame on Leng Ye. He rubbed his head, looked painful, and deliberately sat up with difficulty. "Your hand strength is really... I hope you don't get concussioned!"

"Where have you been in the past two days? Why did you suddenly fall behind?" Yan'er asked with a serious look on her face.

"Yes? Brother, why are you behind? I was shocked at that time. You are just like a small body, if you touch a centipede, you will not be instantly lost! I originally wanted to find you, but I didn't expect to be trapped here and unable to get out. Fortunately, you are fine, and I have been worried about it these two days!"

Mu Chen rubbed his head again, "I don't know either. At that time, I looked at the mural a few times, and then turned around and couldn't find anyone else."

"I thought they were walking too fast, so I hurriedly chased after me, but no matter how I ran, I couldn't see anyone. And the passage seemed to have no end, so I couldn't get out of it."

Mu Chen said it very slowly, and it seemed that he was recalling it seriously. In fact, his brain was flying and thinking about what to say was more reasonable.

"You might be like the woods again, you're crazy?" Leng Ye asked with a confused look on his face.

"Maybe!" After he reminded me, Mu Chen quickly leaned in this direction. "Later, I was really tired from walking, so I sat down and rested, and somehow fell asleep. When I woke up, I found myself lying on the altar, sweating all over."

"Then what?"

"Then I followed the passage and saw the stone gate, and then, that's now." Mu Chen looked at Yan'er with a confused and innocent look on his face, "What's going on? Leng Ye just said, you have been trapped here for two days, so did I sleep for two days?" He knew that Yan'er would definitely doubt the time issue, so he asked himself.

Sure enough, after listening to Mu Chen’s experience, everyone had four big words written on their faces, “I don’t believe it!”

But Mu Chen doesn't care. It doesn't matter whether they believe it or not. As long as there are no obvious flaws in their own words.

"You have a rest, recall the memories well, and see if there are any missing."
