I Only Signed in for a Day, and the Apocalypse Broke Out

Yan Jie, who has been reborn through time travel, is bound to a daily sign-in system at the beginning. Facing a familiar start, Yan Jie said that I am familiar with it! But just when Yan Jie was about to concentrate on surviving and signing it for three to five years, the doomsday broke out the next day. "No way, I've only signed in for a day, and you didn't even tell me that the apocalypse has broken out!?" The introduction is weak, please read the text!
