Otaku Lin Beichen got a mobile phone by chance which took him into a world called Dongdao Zhenzhou. Here he became one of the ten famous generals of the Beihai Empire [Zhan Tianhou] Lin Jinnan's heir. He is also a famous prodigal son, born with a brain disorder. At the time when Lin Jinnan, the Marquis of Zhantian, was defeated, his family was in the middle of the road, and Lin Beichen lost his backer, was blocked at school by various 'enemies' and could not get out. It is a plug-in artifact that can assist in practice. Relying on this artifact, Lin Beichen started his own hilarious counterattack.
