A system called "Endgame" pulls humans into the "mirror dimension". Each copy is a distorted replica of the real world. The conditions for clearance are strange and changeable, and death is the true annihilation of the soul. There is a "symbiont" mechanism in which clearance rewards can be exchanged for attributes, skills, or real-world "privileges." Under certain conditions, two players can sign a "destiny contract" and share health and mental power, but the pain of one party will be directly fed back to the other, and once the contract is concluded, it cannot be unilaterally terminated.
Intention: the meaning of "existence". To be a god who controls everything, or to be a small but true lover? The cruelty of Mugenliu is not only about survival, but also a test of the bottom line of human nature.
