Code Breaker

Wang Yu was an ordinary college student. While playing a popular game, he suddenly encountered a rare game bug and was unexpectedly sucked into the game world. This world was built in a fantasy anime style, with mysterious magic forests, towering elven castles in the clouds, and sinister, terrifying dark dungeons.

Wang Yu discovers that he has possessed a minor character named Airi. The village where Airi lives is often invaded by magical beasts, and life is bitter and difficult.
