Reincarnated into Someone Else's Body from Another World?

The doomsday game is coming, and the ordinary heroine [Bai Ya] in the original world accidentally breaks into the body of the crazy soul [Mu Liqing] from the killing game, and the two souls share the same body. During the day, Bai Ya survives by carefully brushing up credits, while at night, Mu Li Qing takes over and slaughters monsters and goes berserk; the two heroines are attracted by this contradiction of "sometimes cowardly and sometimes cruel", and fight their way through the wasteland from the city dungeon. Until they approach the truth of the end—— "Let me get on top tonight!" "Okay, it's up to you"
