If I let you stay in Lingnan, how could you become the crown prince of the Tang Dynasty?

He traveled through the Tang Dynasty and became Li An, the sixth son of Li Shimin.

As the son of the legitimate daughter of Emperor Yang of the previous dynasty, Li An did not want to be involved in the struggle for imperial power, so he asked to go to Lingnan to be a free and easy prince.

But Lingnan is suffering, so we must do something good for the people!

Building roads, making glass, researching agricultural reclamation, and fighting against mountain bandits and chieftains...

Isn't this what a prince should do?

How did I catch the eye of the Emperor, who insisted that I return to Beijing to become the crown prince of the Tang Dynasty?

Li Shimin: If you don't go to Chang'an to be the crown prince, do you want to rebel against me?

Yuchi Gong: Sixth Prince, can you lend me that musket of yours?

Li Zhi: Sixth brother, if you continue to stay in Lingnan, I will be unable to sleep or eat well!

Wu Mei Niang: Your Highness, I heard that you have developed a beauty pill. I would like to give it a try...
