Trapped in a supernatural survival game, Mo Yi must endure each world until the countdown expires. Before his arrival: participants succumbed to lethal traps, fell to unsolvable mysteries, perished breaking taboos. Upon encountering Mo Yi: struggling contestants desperately cry 'Big God! Big God!

His journey through the nightmare realm, however, uncovers two critical challenges: an overwhelmingly dominant presence drawing unwanted attention, and a baffling teammate whose true nature eludes understanding.
