After Mu Yu saw the appearance of the person in front of him clearly, he called out in shock: "Master?" and immediately stood up.

But when he stood up, the stone chair opposite him was empty, and there was no one.

Is it a hallucination?

The ghost turned his head to look at Mu Yu, who sat down and stood up again, and found that Mu Yu was looking at the empty space in a daze in confusion, and couldn't help frowning. But Mu Yu pretended to bend down and wipe the chair to hide the strangeness just now, and sat down again.

The ghost looked at Mu Yu suspiciously, not caring what Mu Yu was doing.

But Mu Yu's heart set off turbulent waves!

After he sat down, a handsome man appeared in front of him again, with white clothes fluttering, dusty and detached, the wind was light, and his elegant and gentle aura was as reliable as a mountain, as if as long as this person was there, there would be no danger in the world.

Mu Yu's master, Sword Shadow Dust Wind!

Mu Yu scratched his head and looked in the direction of the ghost's life, but found that the entrance of the cave was empty, and he didn't see the ghost's life. He sat down in his chair and seemed to be in another place, isolated from the ghost and his life.

Fortunately, he sat down when he shouted the word "Master" just now, otherwise he would definitely let the ghost find something.

"Master, why are you—why are you here?" Mu Yu asked in disbelief.

"You call me Master, in the future, I will take in the apprentice?" Sword Shadow Dust Wind looked at Mu Yu with interest.

"What do you mean by the future, Master, are you just a residual consciousness?" Mu Yu asked.

He had already seen the residual consciousness of Xuanjizi's real person twice, and now that he saw the young master, Mu Yu naturally thought so.

Sword Shadow Dust Wind sat on the stone chair, looked at Mu Yu, and smiled kindly: "I am a person who lives in the past, and I occasionally come here to see the Tianyan Reincarnation Seal. ”

People living in the past?

Mu Yu didn't understand this sentence very well, but the moment he saw his master, his nose was sore, and the pain in his heart involuntarily surged up.

Even if the master in front of him is a person who lives in the past, does the master in the past know that he will be framed by this traitorous villain in the white world in the future?

"You have my sword intent on you, and my shadow sword, and my naughty sword spirit in your pocket, but your formation technique is not inherited from me, didn't I teach you the formation technique?"

The eyes of Sword Shadow Dust Wind are extremely clear, and they have not seen through the vicissitudes of mundane things, but they are full of wisdom. He sat there like a warm harbor, which made Mu Yu, who had been wandering for a long time, feel at ease. It was also the person in front of him, more than 5,000 years ago, who sealed the Demon King and locked up all the flesh-winged horned monsters to avoid the destruction of the Triple Heaven.

Mu Yu took Xiao Shuai out of his pocket, but Xiao Shuai snorted loudly, and turned over and scratched his belly, not noticing anything at all.

Sword Shadow Dust Wind smiled and reached out and touched Xiao Shuai: "Why is the little guy so tired?

A white mang submerged into Xiao Shuai's arms, Xiao Shuai opened his eyes in a daze, glanced at Sword Shadow Dust Wind suspiciously, and yawned: "Who are you?"

Xiao Shuai's memory is very vague, it doesn't remember Sword Shadow Dust.

Sword Shadow Dust Wind nodded thoughtfully: "Sword Spirit doesn't remember me, it seems that I was reborn, and something must happen in the future that I can't stop." ”

Mu Yu sighed: "Master, my name is Mu Yu. In your future, you said that we couldn't learn the formation, but I still learned it secretly, I'm sorry......"

Sword Shadow Dust Wind laughed: "You don't need to apologize to me, everyone has their own choice, when you think your choice is worthy of your heart, it is right, I don't know if I will teach you these in the future." ”

Mu Yu's heart warmed and nodded.

Master will never blame them, either in the past or in the present.

"Master, a lot of things are going on outside, I don't know how to explain it, and now you ......" Mu Yu didn't dare to continue, according to what Sword Shadow Dust Wind said, he was a person who lived in the past and would not know what would happen in the future. If Mu Yu told Master everything that happened now, Mu Yu wasn't sure if Master would believe it.

"I thought I would never accept apprentices in my life, for me all apprentices are just passers-by, I don't want to boast, but none of the apprentices I have cultivated are general, they will change the order of this world, but I can't easily interfere with this world, and I don't like to watch my favorite apprentices die slowly. ”

Sword Shadow Dust Wind winked at Mu Yu kindly.

An immortal and powerful person, in his long and boundless life, anyone is a hurried passerby in his eyes. He won't die, but the apprentices he takes in will die, and the lover he likes will also die.

And if he cultivates apprentices, with his character of not restraining his apprentices' behavior, he will let the apprentices choose their own lives. His apprentice will definitely shine on one side and become the overlord of one side, influencing the entire cultivation realm.

Over time, after tens of thousands of years, maybe all the sects in the entire cultivation realm will have an inextricable relationship with him, and there will be the shadow of his apprentices everywhere, and there will be his shadow, which is not the result he wants to see.

"In my opinion, the cultivation realm should be diverse, not interfered with by the people I cultivated. If there is the shadow of my disciples everywhere, in the future, all the people in the cultivation realm will only respect my swordsmanship and formation skills, and many magical spells and capable people will gradually disappear, and the cultivation realm will seem monotonous, so I don't understand what will change my thoughts in the future. ”

Sword Shadow Dust Wind was full of curiosity about Mu Yu, and he couldn't figure out why his future self suddenly accepted an apprentice.

It was a young but old sage who didn't want to turn the entire cultivation realm into his world.

But he didn't want to change the world, and the world became a world of traitors.

Mu Yu knew that the master was right, just like Xiang Nan now, he had quietly changed the pattern of the cultivation realm in his own way, and he wanted to fight against the Triple Palace in his own way.

None of the apprentices of Sword Shadow Dust Wind are bad seeds.

"Master, I don't know why you took us as apprentices, but if you want to know, I can tell you everything I've seen over the years. Mu Yu said.

Sword Shadow Dust Wind shook his head with a smile and said, "No need, I'm a person who lives in the past, why do I want to know about the future?" I'm just curious, but I don't want to know." ”

Mu Yu was silent, he would never be able to see through his master.

Sword Shadow Dust Wind stretched out his slender fingers and touched Xiao Shuai's head, Xiao Shuai looked at the person in front of him in a daze, flicked his tail, but did not dodge.

"Why do I seem to have seen you?" Xiao Shuai lay on the table, holding his chin and blinking.

"Little one, since you have been born again, it is normal for you to forget something. Sword Shadow Dust Wind laughed.

Xiao Shuai muttered a few sentences and yawned again.

"Master, can Tianyan Reincarnation Seal really go back to the past?" this is what Mu Yu wants to know the most.

Sword Shadow Dust Wind raised his head and looked at Mu Yu: "It seems that you came here to go back in time, to the past to check out some buried truths. But going back in time is a very difficult thing to explain, and you don't necessarily know what you want to know. ”

"What does that mean?"

Mu Yu didn't understand, going back to the past, he could see a lot of dusty past, such as where the flesh-winged horned monster came from in the past, and how the demon king fought against the meat-winged horned monster, these things Mu Yu could find the answer to himself in the past.

However, Sword Shadow Dust Wind said that after returning to the past, he might not necessarily know what he wanted to know.

"The present man goes back to the past, and he can both change the past and cannot change the past. Many times, one thing that you have done inadvertently in the past can have many different effects. Sword Shadow Dust Wind said slowly.

Mu Yu looked puzzled: "But Xuanjizi Zhenren told me that the past cannot be changed, otherwise there will be many inexplicable contradictions, why do you say that you can change the past and cannot change the past?"

"Let me explain to you like this, you have returned to the past through the Tianyan Reincarnation Seal, you will participate in the things of the past, you can talk to the people of the past, interfere with their decisions, and even kill the people of the past, this is to change the past.

But once the Tianyan Reincarnation Seal takes you away from the past and returns to the present, any traces of what you have done in the past and any traces of what you have changed will be erased, how history has developed and how it has developed, this is the past that cannot be changed, do you understand?"

Sword Shadow Dust Wind explained seductively.

Mu Yu carefully comprehended the words of the sword shadow dust, and he seemed to understand something.

The Heavenly Dao has its own rules, and the Tianyan Reincarnation Seal can allow a person to go back to the past, but it can't change the rules of the Heavenly Dao.

If the trajectory that Mu Yu lives on now is a straight road, with no end and no fork, he will keep moving forward on this road.

The Tianyan Reincarnation Seal brought him to the past, that is, he returned to a certain place where this road had been walked, and at this time, the Tianyan Reincarnation Seal was equivalent to opening up another new fork in the road.

Ki Yu continued along the new path, because his participation changed the history of the new road and led the trajectory of the world to another unpredictable result.

And when the Tianyan Reincarnation Seal brought Mu Yu back, he took it to the original old road, and the new road would disappear, and everything he changed would come to naught, and history would not change anything because of him, but after returning to the past, he would know a lot of things that happened in the past.

"Then why do you say that those who want to know don't necessarily know?" Mu Yu continued.

Xiao Shuai interjected: "I know this, just like the example I gave you last time, we went back to the past, I threw a big stone into the middle of the road, causing the old grandmother to fall and slander the pregnant young lady." The young lady couldn't afford to hang herself, so she couldn't give birth to the child.

And if you go back to the real purpose of the past to know what the big sister's child looks like, but the big sister died before she gave birth, naturally there will be no children, and of course you won't know, so it's equivalent to you burying the truth of the matter, right?"

Sword Shadow Dust Wind smiled slightly, and reluctantly agreed with Xiao Shuai's explanation.

Mu Yu resisted the urge to beat Xiaoshuai, this guy always wants to take him as an example, and he is simply not beaten. However, Xiaoshuai's explanation is much clearer.

It's like he wants to go back to the past to see who stole the ghost gate's "soul crossing and returning to the heart", but if he does something that inadvertently stops the person who wants to steal the "soul crossing and returning to the heart", so that person changes his plan and does not steal the "soul and return to the heart", so that for the past, the ghost gate's "soul crossing and returning to the heart" is equivalent to not being lost, and Mu Yu will not be able to know who this person is.

"So when you go back in time, try not to kill anybody or stop anybody, and don't say something about the future to anybody, so that you can get the answers you want to know, you know. Sword Shadow Dust Wind said.

Mu Yu nodded, and then was stunned again, didn't the master say this mean that he would help himself?

"Master, I thought you would stop me from going back to the past!"

"Since you are my future apprentice, then you can do whatever you want, and I will not stop my apprentice from doing anything, because I believe that everything you do has a clear conscience, don't you?" Sword Shadow Dust Wind smiled kindly at Mu Yu.

Mu Yu felt an inexplicable feeling in his heart, he liked the feeling of being trusted, and the master trusted him, which was enough.
