Great Tang: I'll Teach You How to Be Crown Prince, Then You Can Unify the World

In the eighth year of Zhenguan, Li Er led a campaign in person, entrusting the Tang realm to his younger brother Li Xu to govern in his absence and instructing him to tutor the crown prince.

Li Xu had only wanted to be a carefree prince. To retire as soon as possible, he went and bound himself to the “Strongest Royal Uncle System”!

As long as he could raise Li Chengqian into a capable man, he would receive rewards.

Looking at the timid crown prince, Li Xu flew into a rage. “If you're going to be crown prince, you have to be ruthless! Wipe out the Turks to liven things up!”

And so, the Tang Dynasty's whole style went off the rails.

Li Chengqian: “Uncle, we've wiped out the Turks and conquered Goguryeo too. What do you think about the throne...”

Li Xu pulled out a world map. “See that island? Go conquer it and plant potatoes!”

A year later, Li Er returned victorious. Seeing a golden age with envoys from every nation paying tribute and all the officials kneeling and begging Li Xu to ascend the throne, he was utterly dumbfounded.

“I left you in charge of the Eastern Palace. How did I end up as Retired Emperor?”
