This time, Mu Yu was teleported into a space filled with rows of candles, the candlelight flickering, swaying from side to side.

These candles have no base, all of them appear in mid-air, layer by layer, extending upward, with no top in sight, no clear view of the surroundings, and only burning candles as far as the eye can see.

"What is this place?"

Mu Yu looked around, he tried to fly up for a while, but after flying for half an hour he didn't see any exit, and there were still countless candles around him.

Mu Yu thought that these candles were also some kind of formation, and the floating candles were arranged together, which looked very regular, but when he wanted to think about it carefully, he was confused, and he couldn't see the reason at all.

It doesn't seem like a formation.

"What did you just see?"

At this moment, a little yellow light suddenly floated out of the candlelight, and gradually formed an image of a real person in Mu Yu's figure, appearing in front of Mu Yu. Xuanjizi Zhenren glanced at Mu Yu deeply, and his eyes flashed with a strange light.

"What are the memories of this time?"

Having experienced so many immersive wars, Mu Yu was not so surprised by the sudden appearance of the Xuanjizi real person, he was already mentally prepared to deal with the unexpected situation, and at the same time glanced around to see who the Xuanjizi real person was talking to this time.

"It's just you and me here, isn't it?" said Xuanjizi.

Mu Yu opened his mouth, thinking that the real person in front of him was just an image that he had just seen, but now it seemed that it should be the residual consciousness of the real person of Xuanjizi.

He hurriedly bowed down and said, "Senior, just now I saw how the Sand Eagle Demon King and the White Ape Demon King were sealed, can other people who enter the Demon Town Tower see these images?"

Xuanjizi Zhenren smiled and said: "Others can't see it, that's what I specially guided you to see, because you have seen Akatsuki, and you are still the apprentice of Lord Sword Shadow Dust, and you have his sword spirit by your side, and you are the master of the Array Talisman Gate, so I think you need to know something about the past." ”

Mu Yu nodded thoughtfully, but he still had a lot of things he didn't understand: "What kind of existence is the Moon Clan, why do they want to destroy the Double Heaven, what is the White Ape Demon King resisting?"

Xuanjizi Zhenren stretched out his hand and gently swiped it, and several candles flew over and swirled around his fingertips.

"The Moon Clan is not a thing of this world, and it involves the secrets of the Twin Heavens and the Triple Heavens, and of course the connections of other worlds. I don't know exactly what the Moon Clan is, because they are so powerful, and the Akatsuki you've seen is just their charging soldiers, and I'm afraid only your master knows about it. ”

"But now that the master has been framed by a traitor, he will soon be ......" Mu Yu gritted his teeth and briefly explained the matter between the Triple Palace and the Trapped Immortal Prison.

Xuanjizi Zhenren was silent for a long time before he said: "I didn't know that the current palace master of the Triple Palace would do such a thing, the Triple Palace was originally responsible for the survival of the human race, and in my time, the Triple Palace did not rely on soul power as power. ”

Listening to the description of Xuanjizi Zhenren, five thousand years ago, the Mie Palace was still on the side of justice, but I don't understand why it has changed now.

"The human heart is the most difficult thing in the world to figure out. A thousand years is enough to turn the sea into a mulberry field, and justice can also become evil. Xuanjizi Zhenren sighed.

"Please show me a clear path, how can I find the location of the Mie Palace?" asked Mu Yu earnestly.

"The Triple Palace is at the entrance of reincarnation, and they are responsible for guarding the safe entry of all dead human races into rebirth, and they are equivalent to the messengers of the soul. Xuanjizi Zhenren said.

"How do I find the entrance to reincarnation?"

Mu Yu was slightly shocked in his heart, reincarnation was such a thing as even his master Sword Shadow Dust Wind had said, it was a very mysterious power, and the five Youmeng Spirit Lords were sent into reincarnation by him at the beginning, and they were attached to Mu Yu and the others who should have died young.

The Triple Palace guards the entrance to reincarnation, no wonder they can get the power generated by any dead person in the Triple Continent.

"It can be found by following the soul. Xuanjizi Zhenren said softly.

Mu Yu clenched his fists.

"You have been set up with two very powerful formation techniques, one of which is the protection given to you by life, the power of blood protection to cover the sky and avoid reincarnation, and the other is a rather complex sealing array technique, which even I can't unlock. Xuanjizi Zhenren frowned.

Mu Yu remembered the formation realm of Xuanjizi Zhenren, and hurriedly asked, "Senior, what ability can repair the wounds on the soul?"

He showed the soul fixing array on the jade pendant to the real person of Xuanjizi, and the wound on the chest of the dead wood father inside still looked so shocking.

Xuanjizi Zhenren looked at the Soul Fixing Array in surprise: "Who invented this formation technique?"

Mu Yu sighed and said, "The people in the array. ”

There was a touch of amazement in Xuanjizi's real eyes: "This formation technique is very remarkable, much stronger than the soul control technique of the ghost sect people, it has many special effects, and it is the first time I have seen it." ”

"Can he have saved him? He is very important to me. Mu Yu bowed again.

Xuanjizi Zhenren pondered for a long time, and said: "To repair the soul, you either extract other people's souls to repair yourself like the ghost gate people, or you need to use a very powerful magic weapon, the treasure of the ghost gate people, to cross the soul and return to the heart." ”

"Soul Crossing the Heart?" Mu Yu was surprised, because the people of the Ghost Gate were also looking for this thing!

"Can the seniors have the magic weapon of crossing the soul and returning to the heart?"

Mu Yu remembered that Onihan was going to enter the Demon Town Tower to find such a thing. Doesn't that mean that the soul will fall into the hands of the real person?

But Xuanjizi Zhenren shook his head: "That's something that belongs to the ghost sect, I don't have it." ”

Mu Yu looked at Xuanjizi Zhenren suspiciously, Xuanjizi Zhenren said that he didn't have it here, so what did Ghost Han come here to find?

"The Ghost Gate people are here to find the soul to return to their hearts, but they seem to have lost this thing. Mu Yu told Xuanjizi Zhenren what he heard that day.

Xuanjizi's face slowly became serious: "I understand, it seems that they plan to go back to the past to find the whereabouts of the soul return." ”

"Go back in time, can this be done too?" Ki Yu's eyes widened.

Xuanjizi Zhenren nodded: "One of the abilities of the Tianyan Reincarnation Seal is used to go back to the past. ”

"What!"

Mu Yu opened his mouth wide, he was still holding the Tianyan Reincarnation Seal in the morning! I didn't know how to use this thing, but I didn't expect it to have such an ability to defy the sky!

He suddenly thought of one thing, if he used the Tianyan Reincarnation Seal to go back to the moment when the master laid the trapped immortal prison, as long as he went back and told the master that he couldn't trust the Triple Palace, then the master would not lose his cultivation, and there would not be so many troubles in the future, and Daddy Deadwood would not have an accident.

Master's cultivation is completely capable of stopping what is happening today.

Isn't that a perfect thing?

"It is very dangerous to change the past. Xuanjizi Zhenren continued, his expression solemn and serious.

"Dangerous?" Mu Yu didn't understand this.

"Everything moves forward in this world, and once something in the past changes, then everything is likely to change, and you can't predict what will happen in another timeline, and even the person who goes back to change time will die, so the past will not be changed. Therefore, the past cannot be changed, only seen. Xuanjizi Zhenren said.

"Won't it be changed?" Mu Yu thought for a long time, and quickly figured it out.

It's like if he goes back in time, if he accidentally kills his newborn self, then he won't grow up, he won't come here, and he won't go back to the past, so he won't be able to kill himself.

This is a paradox, so time cannot be changed to some extent.

Mu Yu remembered what Ghost Yuzi said to the ghost just now before entering the Demon Tower: You don't need to meddle in anything, you just need to watch from the sidelines.

This is what Oniyuko said at the beginning!

When the ghost Lao Qi was in the Siren Palace, he was tricked out by Mu Yu, and it seems that he was stolen by a person, who this person may not even know the ghost gate, and the ghost wants to go back to the past, which should be to find out the true identity of this person.

Presumably, the people of the Ghost Sect also know that the past will not be changed, so the Ghost Domain asked the Ghost to spare his life and not spend energy to change anything, as long as he finds out who stole the soul of their sect Zhibaodu.

"In short, it's a very difficult phenomenon to explain, even if you go back to the past, you can't actually change anything, you can't leave traces in the past, but you can see what happened in the past from the perspective of a bystander, and you can change the future. Xuanjizi Zhenren said.

"You can't change the past, but you can change the future? It's a strange thing. Mu Yu said.

The change in the future that Xuanjizi Zhenren said is actually very easy to explain, for example, if a person is killed, and the murderer acts cleanly, there is no way to find the murderer, and the murderer continues to kill more people, and many people will die.

But if after the murderer kills a person, someone goes back in time and sees the murderer's appearance clearly, they can come back and let people catch the murderer. In this way, no one will die at the hands of the perpetrator, and those who were originally killed will live, and their life will change the direction of the future.

However, the future is something that has not happened, and no one can say how seeing the past will change the future, only that going back to the past will make the future more unstable.

Because going back in time and knowing some dusty truths can change the decisions of many people now, and sometimes lead things to the point of no return.

"That ghost gate person should find the layer where the Tianyan Reincarnation Seal is placed, the Tianyan Reincarnation Seal can be opened in the Demon Town Tower, the ghost gate people go back to the past and want to know the whereabouts of the soul returning to the heart, this treasure may change a lot of things, you try to prevent him from going back to the past!" Xuan Jizi Zhenren said.

"I'm going to stop it, senior, can't you stop it yourself?" asked Mu Yu.

Xuanjizi Zhenren shook his head: "I'm just a wisp of residual consciousness, I don't have the ability to do anything, and I can't leave here." I can only point you to something, not what will happen next. ”

"Can the senior tell me which layer the Tianyan Reincarnation Seal is?" Mu Yu asked.

Just now, when I used the Tianyan Reincarnation Seal to open the Demon Suppression Tower, the Tianyan Reincarnation Seal disappeared, and I don't know where I went. And Mu Yu and the others were also randomly teleported away, and they couldn't see where the others were.

"The Tianyan Reincarnation Seal is on the eighty-first floor, you are now on the twenty-seventh floor of the Demon Suppression Tower, you need to go by yourself, there is not much I can do, and this wisp of my consciousness is about to disappear. The figure of the real person slowly faded away, leaving only the sound echoing in the candlelight.

"If you are the apprentice of Lord Sword Shadow Dust, you should shoulder the responsibility of guarding this world, I will not hand over the Demon Suppression Tower directly to you, if you want to control the Demon Suppression Tower, you need to get it by yourself, if you can't do it, you can't talk about guarding the Triple Heaven. ”

Mu Yu shouted, "Then where is the exit from this floor?"

"Where the heart desires, it is the exit. Xuanjizi's voice slowly disappeared.
