During the Zhenguan era of the Tang dynasty, Li Chengqian, the eldest legitimate son of Emperor Taizong Li Shimin, grew resentful of his father's favoritism and the rivalry among his brothers, eventually setting out on the path of rebellion. But the cycle of fate brought him back to life as the newly appointed crown prince. This time, he was no ordinary heir: he was a wise man with memories of his past life. Determined to change the tragedies of his former life, he would use cold composure and intelligence to navigate the tangled struggles of the imperial court, even if it meant treating his father, Li Shimin, more as a sovereign than a parent. His attitude toward Wu Zetian also changed, shifting from a desire to kill her to a decision to keep her in his service, and he eventually brought her into his harem. This is a tale of a crown prince's rise to become emperor, filled with political intrigue, romance, and the turbulence of history.
