Lin Yan, a former top forensic doctor with incomplete memory, was involved in the terrifying infinite flow system of "Abyss Echo". Each copy is a "hell where the resentment of the dead condenses". The rules are the bottom line of survival. If you violate them, you will suffer a bloody backlash. She needs to decipher the truth of the dungeon and collect memory fragments in extreme fear, and gradually discovers that the system is not only a life-devouring prison, but also the "foreshadowing of the world's salvation" that she personally planted - and every reincarnation of the dungeon is a fatal confrontation between her and "the past buried by her own hands."
