Su Xiaomeng, a commoner girl, has a dull personality and lives an ordinary life. One day, the gangster gang "Blue Shark Gang" tried to destroy her entire family in order to compete for underground power, but she managed to survive. Awakening in grief, the 'Cause and Effect Simulator' system can preview the results of different choices. She disguised herself as a cute and harmless girl and sneaked into the Blue Shark Gang. She used system simulations to avoid traps, expose traitors, and provoke power struggles again and again. From a low-level handyman to the core backbone, she gradually disintegrated the gang's internal structure, united with hostile forces to counterattack, and finally took revenge with her own hands and controlled the entire underground world, becoming a new generation of gang queen and stirring up a greater power game. The core selling point is the ultimate intelligent game under the natural appearance. The golden finger of the cause and effect simulator achieves technological crushing. The excitement comes from pretending to be a pig to eat the tiger and the revenge counterattack step by step. The core value is protection and freedom - avenging your family and breaking away from the fate controlled by the gang.
