A university history student gains the ability to create new branches of history, and can transmigrate repeatedly to moments before major historical events. By changing history according to his regrets, he can alter the course of the past. The power is almost godlike, but it turns out everything was destined to happen. A vast boss still lurks behind the scenes, influencing it all. The space keeps changing Zhang Yi's appearance, identity, abilities, and personality. Is the Zhang Yi of the past still the Zhang Yi of today? This isn't a philosophical question, but one thing is certain: Zhang Yi is changing the ultimate course of the world, and even the universe.
