Great Tang: The Fake Imperial Grandson Seizes Li Er's Throne from the Start

Li Chengdao transmigrated and, through a twist of fate, became Li Jiancheng's eldest son after the Xuanwu Gate Incident.

With Li Er intent on wiping out his entire family, should he beg for mercy and wag his tail?

No way!!!

Li Er must die, and the throne must be seized!!!

Fortunately, he obtained a God-Tier Sign-In System. After three years of signing in, he had more trump cards than anyone could imagine.

At a single command, his troops would besiege Chang'an. They would breach the city within three days and take Li Er's head!!!
