Transmigrated into Li Chengqian, he effortlessly ascended the throne and became emperor.

After completing his time-travel mission in the Qing Dynasty, Zhao Heng, with the help of a system, traveled to the prosperous Tang Dynasty and became the five-year-old Li Chengqian.
With an emperor as his father, an empress as his mother, and a face that no one can resist, who could resist becoming the emperor of the Tang Dynasty at its peak?
Li Shimin recently felt that his son with the Empress had changed.
He's a crybaby, clingy, and a tea enthusiast. He often cries because I don't take him for a nap.
But he was also very handsome. Every time I tried to be firm and hold him to the standards of a prince, the little boy would blink his eyes and look aggrieved: "Does Father not love Chengqian anymore? Sure enough, now that you have a younger brother, you don't care about Chengqian anymore."
Li Shimin, a man with a hidden obsession with good looks: "..."
What else could he say?
As Li Chengqian grew up, not only were his siblings vying for his attention, but even the court officials couldn't resist his charm. No matter what reforms he proposed, the officials would let him have his way: "Good, good! Your Highness is right!"
Even Li Shimin relinquished his throne, saying, "My son, I am over fifty years old; shouldn't I retire?"
Li, hesitant and reluctant, declined the throne three times before succeeding to it. Chengqian said, "You all insisted that I take this position!"
