[Crossover] Uchiha and Ye

Uchiha Heye's teacher is his own clan leader. One day, his teacher decides not only to abandon the village he worked so hard to build, but also to run away from home. While trying to stop his teacher from doing something crazy, Heye is knocked unconscious without mercy, and even the Mangekyo he awakened in his agitation is sealed. When he wakes up, he finds himself outside the village, kidnapped by a strange entity called the System. The System gives Heye a comic book and tells him to complete missions. The cover shows the Nine-Tails, Konoha, and a few big words: The Legend of the Five Villages' Battle of Wits, Part One. To find out what happens next in the comic, Heye reluctantly agrees. He then discovers that the System's missions involve all kinds of things he's never heard of, and that it plans to open a Uchiha-exclusive livestream. Later, with the System's help, Heye discovers how vast this world is and how many different species it contains. There's a white-haired man-eating demon with rainbow-colored eyes who says he's bewitched by Heye and wants to make him happy. There's a sword demon with six eyes and markings on his face who insists that he's also descended from the Tsugikuni family. There's an incredibly powerful demon king who's just as terrified of dying, a strange creature who claims to be from the same era as the demon king but is actually a brain, and an obnoxious white-haired man with six eyes who can't be hit no matter how hard you try. Most importantly, there's the barrage of comments that keeps spoiling everything for him: [Your teacher got fooled by a blob of darkness and is planning to make the whole world dream!] [Your teacher's younger brother was killed by that blob of darkness, and it ripped out your teacher's heart too.] [The Uchiha will eventually be wiped out, and their last surviving descendant won't even be able to afford an apartment in Konoha. He'll still be stuck with a mortgage!] Heye: "..." Hold on. I'll go tell my teacher to get to the moon first. Theme: The bold, untamed spirit of youth
