Night.
Xuantian University.
At three o'clock in the morning, the university campus shrouded in darkness was completely silent.
Occasionally, the sound of insects could be heard from some corners. After a while, it would disappear.
Under the moonlight, a ghostly figure streaked across the sky and emerged from the clouds, landing on the rooftop of a building in the northeastern corner of the campus.
The top structure of this tall building was rather special. It was like a bowl was placed upside down at the top.
As a result, moving from the rooftop to the windows required a huge turn.
If it were anyone else, they would have taken quite a bit of effort to enter the window from the rooftop.
