Chen Guo SSS Level File Code Name Back Room

[Top Secret File No. KS-001] Project code: [Anchor Point] File Level: SSS Top Secret Known information: The back room - a layered space with a disordered spatial structure that unexpectedly overlaps with our world. We have cleared the "lv.-1" Level and established an advance base. But in the mirror deep in the base, there is the unexplored "level lv.0". I will pass through the "mirror" and become the 10,001st person to step into "Level 0". I must come back alive.
