Shen Qingli received a mysterious black letter and was forced into an "infinite game" with life as the bet. Her first dungeon was the "Blood Castle", which was full of dangers and rampant with ghosts.
You can only pass the level if you survive for 72 hours or uncover the dark secrets hidden in the castle.
But while other players were busy escaping, Shen Qingli found that he had attracted special attention from Jiang Mo, the owner of the castle and the ultimate boss of the dungeon. This powerful, mysterious and non-human being was supposed to be the embodiment of cold-blooded rules, but he made exceptions for her time and time again, giving her subtle hints and protection.
On one side are the terrifying death traps and player companions with ulterior motives; on the other side is the dungeon BOSS who has opposing identities and a mysterious purpose but shows tenderness to her.
The truth behind the massacre in the old castle was gradually revealed, and Jiang Mo's painful past surfaced. Shen Qingli realized that the condition for clearing the customs may not be escape, but...
Join him in breaking this eternal curse.
Is the encounter between the BOSS and the player a system flaw, or is it destiny? In an endless game of life, can they be each other's only salvation?
