Lin Xian is an ordinary office worker who, after repeatedly having the same dream, is transported to the Virtual Realm. As negative emotions in the real world continue to grow, a monster called Sèna comes into existence in the Virtual Realm. These creatures represent negative energy, and Lin Xian must eliminate all the Sèna in the Virtual Realm before he can return to the real world. Together with his companion He Xiaohua, Lin Xian encounters all kinds of challenges and experiences in the Virtual Realm. At first, he only cares about looking after himself, but his experiences there gradually lead him to sincerely realize how meaningful it is to help others.
