He traveled through time and became the crown prince of the Tang Dynasty, Li Chengqian, who gradually lost favor. His younger brothers coveted his position, and there were loud calls from the top of the court to dethrone the crown prince. As a result, the assassination of his younger brother happened, and the crown prince's supporters filed in, talking about following Li Er's example and launching another Xuanwumen incident. Li Er, who knew full well that his unreliable teammate could never defeat the rebellious professional, should he sit back and wait for death. No, since I have come from this era, I have never thought about it**. Li Chengqian visited the head of the Five Surnames and Seven Hopes at night, and this behemoth family gradually showed its claws. "Father, please abdicate. Don't worry if the Tang Dynasty is left in your hands." A few months later, Li Er heard in the palace that the city of Goguryeo was destroyed and the king committed suicide. A year later, during a chess match between Li Er and Li Yuan, Li Er lamented that Tubo, as powerful as Tubo, could not defeat the Tang Dynasty Iron Army in a single battle. Many years later, when Li Er was about to die, he shouted: 'I am not as good as my son, the Tang Dynasty is so powerful! ' This novel and its characters are purely fictitious.
