The otaku Lin Beichen got a mobile phone by chance, and the mobile phone took him into a world called Dongdao Zhenzhou, where he became one of the ten famous generals of the Beihai Empire [Zhantian Hou] Lin Jinnan’s heir. He is also a notorious prodigal, born with a brain disorder. At the time when Lin Jinnan, the Marquis of Zhantian, lost the battle, his family was in the middle of the road, and Lin Beichen, who had lost his backing, was blocked in the school by various ‘enemies’ and could not go out. It is a plug-in artifact that can assist in practice. Relying on this artifact, Lin Beichen started his own way of hilarious counterattack.
