To avoid getting caught up in the chaos of the times, he takes a group of talents who have yet to make a name for themselves and travels far overseas. He also unexpectedly whisks away Princess Li Lizhi, the eldest daughter of the emperor, who has been concealing her identity. Several years later, he has established the Ming Dynasty and commands a powerful nation. He and Changle also have a daughter, Xu Qinghe, a little devil with innate superhuman strength. Who would have thought that seven-year-old Qinghe would secretly sail back to Chang'an and blast open the city gates with a cannon while searching for her maternal grandfather? Only when Li Shimin discovers that this lawless little girl before him is actually his own granddaughter does he realize that her father is an emperor overseas.
