All Heavens: My Future Self Has Announced Death to Me

Late at night in the hospital, I met my future self. He looked exactly like me, but his eyes were so cold that he didn't look like a real person. He said that in three minutes, many people would be dead on this floor. I don't believe it. Three minutes later, disaster really struck. Just when I was about to die, my future self threw me into the first world and gave me the first task: survive. From that day on, I began to travel through familiar and unfamiliar worlds one after another. The city is sealed off by zombies, the academy is forbidden, the spy war is lost in the city, the dynasty is in chaos, the mecha apocalypse, the regular hospital... I thought this was his salvation, but later I learned that this was his screening. Because he wanted to know if I would see that version of myself from the same starting point.
