I, Li Chengqian, Will Not Become a Deposed Prince.

"Cheng Qian, you are so ill, how will you lead the world in the future?" Li Shimin's voice was filled with worry. Li Chengqian cupped his hands with a firm gaze: "Father, my son's illness can be cured, and the future of the Tang Dynasty can even be cured!" He knew that he not only had to reverse the tragedy of "the prince was deposed", but also find out the truth about "the murder of Zuji" in the previous two lives; not only must he keep the position of the prince, but also create a prosperous era in which "the noble families bowed their heads and the barbarians came to court". After all, this is the third time he has lived in this Zhenguan period. This time, he must not lose again!
