In this world where logic is fragile and sanity is scarce, strange phenomena called "unknown" are constantly eroding reality. They use "weird objects" as a medium to rewrite common sense with twisted rules. Shangguan Wudu belongs to a secret agency called the "Containment Department", which is responsible for dealing with these anomalies that cannot be measured by common sense. He is not the strongest, but he can always become the most efficient operator with his unique talent of understanding strange logic. The story will follow him as he investigates a series of containment breaches and new unknown events, uncovering the terrifying truth behind the strangeness, and the heavy price to pay to protect the world.
