I Go Wild in the Great Tang and Handle the Face-Slapping

On the first day after I transmigrated, I saved the crown prince who was supposed to die of illness in the future.

On the second day, I shoved the future emperor's head into a chamber pot.

On the third day, I turned the whole Tang dynasty upside down.

What? The crown prince who was supposed to die of illness is my brother-in-law?

They say I'm an idiot, so I'll start an underwear company with Emperor Xianzong of Tang.

If they try to kill me, I'll confiscate your entire estate.
