Shang Yun, a reptile pet shop owner, due to an accidental fire, brought his reptile pet babies and several pets to cross into a Western fantasy magic game world that had already shut down its servers, entering the shell of his own max-level elven archmage account in the game. World Will Wei Luola told him that this game world needed his help. The moonlight mash potion in the game that can bring the dead back to life and create an undead legion has its only formula in Shang Yun's hands. A black dragon that does not exist in the game, descendants of the lich clan, the goddess of death, this game has gradually begun to appear bugs.
