Is the Fairy World Destroyed Today?

Demon Lord An Gu woke up and found that he had "shrunk". Bad news: He's regressed back to his four-year-old body Good news: He is not the only one who is unlucky, everyone's time has been turned back. Bad news: The demon world has returned to the chaos it was before unification. Something went wrong, and the people in the fairy world "rescued" him as a poor orphan. Good news: No one except him retains the memory of before time travels back. Lord Demon Lord has always been able to bend and stretch. It doesn't matter if he comes to the fairy world, or if he becomes a little brat, let's see how he uses this identity to disrupt the world and destroy the fairy world! As the saying goes, the little ones are the future of the world of immortality. To destroy the Immortal Sect, you must start with the little ones. In order to penetrate into the "future of the Immortal Sect", Lord Demon Lord has lived a life of going to school every day with a group of little ones. In this school, there are not only the arch-enemy who is regarded as the leader of the Immortal Sect that he will dislike the most in the future, but also the level-up maniacs who often come to their demon world to gain experience, as well as the medical experts who have saved the lives of the fragile Immortal Sect countless times... In order to nip these "immortal futures" in the cradle and leave them with lingering psychological shadows, Lord Demon Lord wakes up early every day and practices the basics of immortal magic taught by the teacher. He frantically rushes to answer questions in class. After class, he uses the introductory immortal magic to crush and taunt the little cubs and seize the spot in the fairy cub competition... After a while, he realized that something was wrong Zaizai, a master of medical skills: Phew~ Finally I don't have to shovel poop for mice anymore, I'm so happy~ Upgrade the crazy Zaizai: With Gu Gu, the teacher doesn't even have the chance to ask us to answer questions, so we can doze off while reading the textbook in class! Zaizai, the social enemy who was squeezed out of his place by Lord Demon: Well... Thank you Gugu, thanks to him. Under the tireless operation of Lord Demon Lord to "destroy the fairy world", finally—— Lord Demon Lord has become the most popular Zaizai in the fairy world. Lord Demon Lord:? ? ? Lord Demon Lord:... Lord Demon Lord: I'm tired, and I'm autistic. Motto: When you want to change the world, the world will also change you
