Jiang Cui mistakenly entered the SSS-level dungeon Blood Moon Manor, pretending to be mentally retarded to save his life, and was raised by the dungeon boss as "Xiao Cui". The two gradually became bonded as they got along. After Jiang Cui cleared the customs and returned to reality, he was forced to recall due to a special anchor point. After going through the system compliance review, he met other awakened dungeon cores one after another, and also learned the truth that he was the prototype of the system. In the end, the boss sacrificed all his power and became a mortal. Jiang Cui rewrote the underlying rules of the system and gained freedom for the awakening core. The two joined hands to start an ordinary and warm real life.
