(Twenty thousand people have already ordered this old book, so you can enter the trap with confidence.) Traveling through the Tang Dynasty, becoming the prince Li Chengqian, and arriving three months before the prince's rebellion. Just when Li Chengqian was figuring out how to deal with his mess. But when he woke up, he found that he had woken up from the dragon bed. Um? Wait, I became my father? Broken! Gu's rebellion plan! On the other side, His Majesty Li Er, who woke up from the East Palace, slapped his thigh fiercely. Broken! My home, country and country! … Li Er, who was born with the destiny of being the protagonist, obviously did not understand His Highness the Prince's psychological changes from normal to distorted, and planned to set an example to make His Highness the Prince realize that the difficulties he faced were not insurmountable. So, when "His Royal Highness" weighed his lameness and worked hard to become stronger, he faced doubts and tried to overturn the mountains in the hearts of his ministers. "His Majesty the Emperor" who was smacking melon seeds expressed full affirmation and encouragement. When His Highness the Crown Prince's reputation was finally successfully reversed, all the ministers burst into tears and praised His Majesty the Emperor for his good parenting and family harmony. Classmate Li Er, who finally returned to his own body, suddenly realized something was wrong when facing His Highness the Crown Prince who actively returned his rights. I've been asked to do all kinds of work, and my reputation and enjoyment all belong to this coward? Even this coward... Still plans to let me continue to do this!
