Reborn as Li Chengqian, Crown Prince of the Tang dynasty, he retains the memories of a modern middle schooler. He strengthens his body early to avoid a leg ailment, then feigns a limp to conceal his true abilities.
He quietly builds a network of civil officials and fierce generals, secures sources of wealth, and works with the Crown Princess to lay out a plan for the inner palace. Watching his brothers clash in court, he advances cautiously, steadily securing the imperial throne.
