When the Demon Venerable Angu woke up, he discovered that he had "shrunk."
The bad news: his body had reverted to that of a four-year-old.
The good news: he wasn't the only one hit by bad luck. Everyone's time had turned back.
The bad news: the Demon Realm had returned to the chaos of the era before he unified it. Then a little mishap occurred, and people from the Immortal Realm mistook him for a pitiful orphan and "rescued" him.
The good news: apart from him, no one retained their memories from before time reversed.
The Demon Venerable has always been able to bend without breaking. Coming to the Immortal Realm is no big deal, and neither is becoming a little kid. Just watch as he uses this identity to throw the world into chaos and destroy the Immortal Realm!
As the saying goes, little kids are the future of the cultivation world. If he wants to destroy the immortal sects, he has to start with the kids. To infiltrate the "future of the immortal sects," the Demon Venerable begins spending every day at school with a group of little ones.
Among his classmates are not only the sworn enemy he can't stand, who will one day be revered as the leader of the immortal sects, but also an upgrade-obsessed maniac who keeps coming to the Demon Realm to grind monsters, and a master healer who will save the lives of the immortal sects' fragile disciples countless times...
To nip this bunch of "future immortals" in the bud and leave them with a lifelong psychological scar, the Demon Venerable gets up at the crack of dawn and studies the basic immortal arts taught by his teacher. He frantically answers questions in class, trounces and taunts the little ones with beginner immortal arts after school, and snatches the spots for the Immortal Disciples' Tournament...
After a while, he realizes things have started to go a little wrong.
Little master healer: Phew, I don't have to shovel the lab mice's poop anymore. I'm so happy~
Little upgrade maniac: With Gugu here, the teacher never gets a chance to call on us. Now we can read storybooks and doze off in class!
Little socially anxious sworn enemy, whose spot was taken by the Demon Venerable: Um... Thanks, Gugu. I-I really appreciate it.
After the Demon Venerable's tireless efforts to "destroy the Immortal Realm," the result is...
The Demon Venerable becomes the most popular kid in the Immortal Realm.
The Demon Venerable: ???
The Demon Venerable: ...
The Demon Venerable: I'm tired. I'm shutting myself away.
