Lu Yuan is trapped from the start in an S-rank rule space, the Elevator of Life and Death. At the brink of despair, he awakens an SS-rank talent for interpreting rules!
The rules say the fourth floor doesn’t exist? I’m going anyway!
A red-clad ghost chases me? I spot the loophole in the rules at a glance!
The Anomaly Bureau, the Pact Society, the Night Watch, the Entropic Apocalypse…
I wield the rules as a blade and break through every supernatural threat!
A tsundere beauty, a yandere protector, and a gentle healer by my side,

Under the rules, I am the truth!
