My main world is in Naruto

Cuizi: "Actually, there is a place where even if the mountain god is lost, he won't be able to find it."

Platycodon: "You don't mean the underworld or the underworld? Where can a mountain god be trapped in a place like that?"

Cuizi: "The dimensional monster is the pillow monster! Like the teabag, it is a monster that leads to the dimensional world. The teabag monster can return people's souls to the past they least want to see. The pillow monster can send people to the past they least want to see. See the future.”

Kikyo: "The past is hard to change, but the future can be changed through hard work. This pair of monsters is really interesting. How come there are these two kinds of monsters in the world?"

Cuizi: "Maybe it has something to do with the closing timeline? A certain change will create parallel worlds, and so many parallel worlds are a burden to the universe. Changing the timeline through tea bags and anti-pillow monsters makes the timelines of parallel worlds Fusion thus closes the timeline and reduces the existence of parallel worlds.”

Platycodon: "Is it true that happiness is mostly the same, but misfortune is different? Let people work hard to reduce various misfortunes and create the same kind of happiness. In this way, the integration of the two timelines maintains the stable development of the universe?"

Cuizi: "That's probably it. Maybe this universe itself has put a certain burden on the universe because of too many parallel worlds. Through bone wells and tea bags, anti-pillow monsters. Converging the timeline and reducing the burden on the world can make the universe last longer. A little?"

Kikyo: "Yeah! The Marvel Universe also has a Time Management Bureau. It is to try to unify the timeline and reduce the increase of parallel universes. It is a kind of protection for the universe itself. And like the Dinosaur Express, which attacks the past, it will The world that will have an impact in the future is a single world. In fact, this kind of world is almost reaching the end of time. Space is drifting on the long river of time. The narrower the long river of time, the fewer parallel worlds. At the end of time, will the time of the world become infinite or will it become stationary? Return to nothingness?”

Then Kikyo and Cuizi chatted some more.At night, Cuizi took Platycodon's soul into the Jade of Four Souls.Then he controlled the Shikon Tama to lurk in the body of one of Narusuke's students named Goko.

Twelve o'clock at night.The anti-pillow monster reversed Goko's pillow.I saw Xiangzi's soul being pulled into the air, and the anti-pillow monster danced when he saw it.In an instant, Xiangzi's chest lit up with colored light, and he immediately took the anti-pillow monster inside.

16 years later.

Xiangzi’s mother: “Xiangzi, wake up, you’re late!”

Xiangzi: "Ah~ It's just six o'clock? Is it too early for school to start at eight o'clock?"

Xiangzi's mother: "School? Are you out of your mind? You are 26 years old. Why else do you go to school?"

Xiangzi: "Huh?" I remember I was only an 11-year-old primary school student?Wait, it seems that I have graduated from elementary school long ago.secondary.high school.University.I have been employed for four years after graduating from college: "Ah! I'm going to be late for work!"

Xiangzi’s mother: “I said you were confused by your sleep, right? You’re still wearing pigtails. Do you think you’re a primary school student?”

Xiangzi: "Ah! It's late! It's late! I'm out!"

A voice suddenly appeared in Xiangzi's head: "Wait a minute."

Goko: "Ah! This is Lord Kikyo's voice!"

A soul appeared in front of Xiangzi.

Xiangzi: "Lord Platycodon!"

Kikyo: "Xiaozi, please calm down. You have been possessed by the anti-pillow monster's magic and come to the future. In fact, you are still a primary school student now."

Goko: "Yes? Right! I just said it was weird. Does Lord Kikyo have any way to go back?"

Kikyo: "This is very simple. You can go back to the past by turning your pillow upside down and sleeping at twelve o'clock in the evening, but there are two things that need your help before that."
