Invite the Tang Dynasty Prince Li Chengqian to Ascend the Throne

Li Shimin, Emperor Taizong of the Tang Dynasty, known as the "Four Great Eternal Emperors" in history, encountered the problem of successor during his glorious rule and failed to successfully select a crown prince. Against this background, the protagonist's soul traveled to the early Tang Dynasty and possessed Li Chengqian, the eldest son of Emperor Taizong of the Tang Dynasty, and found himself trapped in a desperate situation of political struggle. Faced with the suspicion and suppression of his father Li Shimin, the overt and covert struggles of his younger brother Wei Wang Li Tai, and the potential threat of Jin Wang Li Zhi, Li Chengqian decided not to hold back and vowed to change his destiny. He challenged the established destiny with firm determination and fearless courage: "I dare to pull down the emperor even if I am willing to be killed!" Li Chengqian expressed his unwillingness to repeat the same mistakes and become a tragic figure like his uncle Li Jiancheng, nor to accept that he was considered unfit for the throne due to physical defects. He realized that even if the Zhenguan period was built into the most prosperous era in ancient and modern times, history books would not give a fair record if he was not succeeded in succession. In this power game, Li Chengqian even prepared for the worst and expressed his willingness to accept any form of punishment in order not to give up his position as prince.
