This is a training and strategy game. People who play the game unscrupulously develop or defeat NPCs in the game world. After the training and strategy task is completed, they abandon the target NPC and forget about it. Luo Erna is the first NPC to awaken in this development game.
(Background explanation: This is a real world where laws are higher than human rights, and games have become a channel for everyone to vent their negative emotions.)
