He travels back in time to the Tang Dynasty and becomes the eight-year-old Crown Prince Li Chengqian.
Knowing history well, he knew that being a crown prince was a high-risk job, requiring one to get up earlier than the rooster, sleep later than the dog, and ultimately be exiled!
Li Chengqian immediately decided: Whoever wants to be the crown prince can be one!
At his coronation ceremony, he threw down a memorial in front of everyone: "Father, I am young and frail, and request to resign from my position as Crown Prince. I only wish to return to the Eastern Palace to live out my retirement!"
Li Shimin was furious: "You're only eight years old, what are you doing raising an old person? Get out of here and go oversee the country!"

Turkic Khan Jieli: "I was just passing through, why did Li Chengqian's private army chase me for eight hundred li?"
The five prominent families and seven noble clans pleaded, "Please, Your Highness, retract your supernatural powers! We are willing to hand over all our wealth, just please don't let the Embroidered Uniform Guard knock on our door!"
Looking at the prosperous scene of all nations paying tribute, Li Shimin shed tears of emotion: "Chengqian, I am old, this throne..."
Li Chengqian was truly anxious this time, and took out an elixir of immortality and stuffed it into Li Shimin's mouth:
"Father, you are in the prime of your life! After taking this medicine, you can easily serve for another five hundred years!"
"Your son... really just wants to retire!"
