Double World Travel: Madman at the Top, Genius at the Bottom

[Double Realm Travel + Strange Arrival + Infinite Apocalypse + Psychotic Protagonist] The rating they gave me was: level 4 high risk, persistent violent tendencies, no contact. They said I was talking nonsense and a complete lunatic. But they don't know that what I call "sickness" is traveling between the current "reality" and the doomsday parallel world seven days from now. There, human fears were embodied, with subways slashed in half, monsters raging, and memetic pollution sweeping the city. I traveled through purgatory again and again, trying to bring a way of life to everyone, but I was only treated as the ravings of a lunatic. Fortunately, in the world seven days later, someone can hear my voice. Genius and madman are two sides of the same coin. I shuttled between the two worlds, trying to snatch everyone's life back before the end came.
