The Strange Containment Facility: You’re Containing Me, a Human, Alone?

[No System] [No Female Lead] [Cthulhu] [No Formula]

Also titled: Sequence: Ascension to Godhood

The dark prison and reality merge, and eerie creatures invade the real world through 'doors.' A organization quietly comes into being, calling themselves the prison guards. They block the eerie beings outside the 'doors,' and capture and contain the eerie creatures that run into the real world.

Lu Xiao accidentally falls into the dark prison and lives there alone for three years. After being discovered by the prison-guard organization and taken out of the dark prison, he becomes an S-class contained object with an official position.
