Since the New Year, everything has changed.
Tens of thousands of people disappeared inexplicably in the small town in one day. Dozens of corpses were fished out from the lake, blood moons, comets... People were anxiously speculating: Could it be that the end of the world has come?
Until one day, Su Xian discovered a terrible problem in the dormitory: this did not seem to be his original university.
A knock on the door in the middle of the night, a roommate behaving strangely, a panicked cry for help... After everything settled, Su Xian heard a child-like playful laughter: Welcome to the world of night.
Intention: Study hard and make progress every day.
