Ling Jiushi, a VR game designer, decided to resign due to the frustrations at work. A beta game named "Spirit Realm" helped him forget his worries. Just when he was struggling to find the complete version of the game, he unexpectedly received a game disc sent from abroad. After a car accident, he found himself in a corridor with twelve iron doors. Entering through one of the doors, a mysterious person helped him escape from the clutches of wolves in the forest and snow-capped mountains and welcomed him to the world behind the doors.
