Unemployed young man Zhang Yi accidentally activated the fantasy system. He thought it was the beginning of a counterattack in his life, but he unexpectedly stepped into a shocking conspiracy that spanned twenty years. From a hero saving a beauty in a convenience store, to a life-and-death fight with a mechanical monster, to uncovering the double-sided truth of the Ouyang family - he discovered that the entire world is a carefully designed mirror cage. When the savior turns into the mastermind behind the scenes, when the lover becomes the experimental container, and when the system rewards hidden fatal traps, can he use fantasy energy to tear open the cracks in reality in the desperate situation where reality and reality are intertwined? And behind the constant countdown to the crisis of destruction, it actually involves the disappearance of parents, family secrets, and a "deus ex machina" plan that can overturn the world! The ultimate showdown about memory, bloodline and truth begins.
