After studying for a long time, Chu Chen had no clue, and in the end, he had to close the scroll and put it back on the shelf, perhaps, only when he entered the tenth realm of the Demon Realm could he know the true meaning of these words.

Demon Realm, Chu Chen didn't go to the previous life, after he left the Nine Realms in his previous life, he only came back once, took care of some of the descendants of the old people, and worshiped those who had died, brothers, and friends, at that time, when he came back, he went through the Nine Realms seriously, but he didn't find the existence of the Tenth Realm.

"Perhaps, those murals are fake, in this world, there is no Tenth Realm. Chu Chen shook his head, he was a little suspicious that what was painted on the mural might be fake, but his heart told him that it was true.

The memories of the previous life, which are common in this life, made Chu Chen a little confused.

"It's useless to think too much, let's look for it when we go to the Ninth Realm in the future. Chu Chen shook his head, and after taking a turn on the fourth floor, he walked up to the fifth floor.

The fifth layer is the same as the fourth layer, there are bookshelves, but it is obviously much less than the fourth layer, Chu Chen casually picked up a scroll and opened it, sure enough, just like he thought, all the words on it were divine scripts, and he couldn't understand any of them.

After that, Chu Chen went up to the sixth layer, the seventh layer, and the eighth layer, and the result was the same as the fourth layer, except for the bookshelves, there was nothing, but, every time he went up, there were many fewer bookshelves in it, and when he came to the eighth layer, there was only one bookshelf in it, and only one scroll was placed on it, and inside, it was still that kind of divine script, which was completely different from the current text or the text he had seen in his previous life, this was a kind of text that had never been circulated among the human race.

Chu Chen came to the ninth floor, only to see that the ninth floor was hollow, there was only one stone platform, Haotian Tower floated in front of the stone platform, and there was a striped road painted on the stone platform, crisscrossing it, as if it was scribbled, but Chu Chen recognized it at a glance, these lines were used for other purposes, on this stone platform, there was also a thing, it was a cracked thing, it seemed to be the body of a layer of towers, yes, yes, it was a layer of towers! Moreover, it was also a layer of towers of Haotian Tower!

"Is this your tower body?" Chu Chen walked over and asked, Haotian Tower Instrument Spirit quickly gave Chu Chen an accurate answer, saying that the sound that he began to hear to summon it came from this tower body.

"Why don't you take it?" Chu Chen asked, and the Haotian Tower Instrument Spirit told Chu Chen that its section of the tower body is where the array eye of the entire Purple Cloud Secret Realm is located, once it is taken away, the entire Purple Cloud Secret Realm will collapse, unless someone cracks the formation pattern on this stone platform, otherwise, it can't take this section of the tower body, just now it used the connection between this tower body and it, and only then opened the door of this tower and let him in.

"Whether I can retrieve this tower body or not depends on you, master. Haotian Tower Instrument Spirit said to Chu Chen.

Chu Chen bowed his head, his eyes fell on the stone platform, raised his hand, and stroked it gently, and then, his eyes slowly closed, and his divine consciousness fell on the stone platform along his hand, covering it, and began to deduce quickly, this is not the formation drawn by the monk, this is the heavenly god formation, which is completely different from the formation knowledge that Chu Chen mastered, these formations are extremely complex, even Chu Chen, he can't find a clue for a while, but he believes that no matter what the law is, in the end, it will be the same way, and the three thousand avenues will all end up in one point.

Soon, Chu Chen was immersed in the deduction, studying the formation and knowing that he was in no hurry, he calmed down and deduced slowly, he didn't believe that with his attainment in the formation and the power of his comprehension, he would not be able to study the mystery of this formation.

Chu Chen was completely immersed in it, time passed day by day, he completely forgot the time, and the Haotian Tower Instrument Spirit didn't bother him, so he let Chu Chen study it like this, Chu Chen stood there, as if it was eternal, motionless, with no expression on his face.

Time passed day by day, and in the blink of an eye, the past ten, twenty, thirty, fifty days......

As soon as the one-month period of the Purple Cloud Secret Realm passed, all the monks were teleported out by an invisible force, but Chu Chen in the giant tower was not teleported out, but was left here, no one knew, when all the monks were teleported out, there were still people who could stay in the Purple Cloud Secret Realm, if this news was known, it was estimated that the entire Xiuzhen Realm would explode, because for countless years, no one could stay in the Purple Cloud Secret Realm for more than a month, and it was rumored that if the person who could stay in the Purple Cloud Secret Realm forever was recognized by the Purple Cloud Secret Realm, the Purple Cloud Secret Realm would belong to him alone！

When the Purple Cloud Secret Realm was closed, the three major sects had already mobilized tens of thousands of disciples from within the sect to surround the entire Purple Cloud Secret Realm, looking for the person who killed the disciples of the three major sects, but they checked everyone, but they found no trace of Chu Chen, some people suspected that Chu Chen died in the Purple Cloud Secret Realm, but Zhan Chengming and Feng Youdao did not believe it, because Chu Chen's ability they had seen with their own eyes, he could not die in the Purple Cloud Secret Realm like this, they did not give up, they waited outside the Purple Cloud Secret Realm, but after a few months, they could not wait for Chu Chen, and finally they could only return to the sect。

Chu Chen stood there, motionless, for five months, six months, a year! He was like a statue, as if he had been petrified.

Year and month passed, finally, there was a trace of change on Chu Chen's face, but this change was very subtle, even if someone next to him estimated that he couldn't find it, one day in the second month of the year, suddenly, the formation pattern on the stone platform suddenly lit up, in the third month of the year, the formation pattern on the stone lit up the second way, in the fourth month of the year, the formation pattern lit up nine times in a row, in the fifth month of the year, the formation pattern on the stone platform lit up more than half, and every month passed, the formation pattern on the stone platform would light up more, when the time was about to come to the second year, finally, the formation on the entire stone platform was all lit up, at this time, A smile appeared at the corner of Chu Chen's mouth, and he slowly opened his eyes, but the eyes he opened had become blood-red at this time, and they were full of bloodshots, and his appearance was also thin, in addition, his face was full of exhaustion, it can be seen that in the past two years, he has been deducing the formation pattern and has not rested for a moment.

As soon as Chu Chen opened his eyes, he felt a little dizzy in his whole body, and the mana in his body turned around, and he was only slightly better.

Chu Chen raised his hand, picked up a section of Haotian Tower on the stone platform, turned around and threw it to Haotian Tower, Haotian Tower's body flashed, and he connected this section of the tower body, so that Haotian Tower had another layer.

"Master, thank you!" the voice of the machine spirit came, expressing his gratitude to Chu Chen.

"You're welcome, I need a good night's sleep, you can play by yourself. Chu Chen looked at Haotian Tower and smiled, and then lay down on the ground and fell asleep, this sleep was almost a month.
