The virtual game Domains at War is a globally popular immersive MMORPG. Players enter using neural-link devices, and its world, Aesos, features a highly realistic ecosystem, civilizations, and storylines.
The protagonist, Moluoke, is the ultimate demon king who rules the Abyssal Rift in the game. His role is to serve as the ultimate challenge for players. He wields world-destroying power, yet the System strictly confines him to a fixed area and storyline.
After being "killed" and reset countless times by players, Moluoke gradually awakens to self-awareness. He begins to question the repetition of "death" and the "false" existence of players, then explores the boundaries of the game world and the meaning of his own existence, all while fighting the System's "corrective mechanisms" and the players' unrelenting challenges.
