Good Brother, Just Let Me Take a Bite.

Why did my cheap brother disappear? What do you mean he is in my belly? As promised in advance, you will have to bear the rent with me even if you are in my belly! When Lin An woke up, everything became different. Disappearing brothers, strange deans, new beautiful teachers, weird boxes, and various strange powers appear frequently. All of this has to start with the time travel 7 years ago. When Lin An opened his eyes, he found that he had traveled to a contradictory world where technology and religion prevailed. He had been wandering, happy, sad, and angry. Facing various crises in the strange world, would you choose to destroy or save? The moment you uncover the truth about the world, will you choose to return to the original world or the friends you have now?
