A space crisis has arisen on the surface of the earth
Everyone who enters the space will never return.
An abyss is constantly swallowing people on the earth

At this time
In math class at Nanting No. 2 Middle School
Lu Sui slept peacefully
As a result, I was forced to get up the next second
As soon as I open my eyes
Everywhere you look is wilderness
