The Mad Prince of Tang Dynasty, Inheritance of the Sword Saint at the Beginning

Reborn in the Tang Dynasty, he became Li Shimin's unpopular mad son Li Kuan, and awakened the system of pretending to be crazy and selling stupid.
If you want to be crazy, then go crazy to the end.
They are all lunatics. It is not too much to ask for the crown of the prince in front of the Xuanzheng Palace, right?
It's not too much to rob civilians in the street, right?
It's not too much to rub other princes on the ground.
As for single-handedly fighting Li Jing, demolishing a few temples, and destroying a few Taoist temples, it's not too much.
Crazy is crazy, not completely crazy, how can it be worthy of the name of Crazy King Li Kuan.
