The Tang Dynasty's Fiefdom King

If you don't like stories where the protagonist suffers terribly, don't read this one. It's extremely angsty for the protagonist...

If you like equality so much, why go to ancient times?

The protagonist's IQ is pathetic; he likes to argue with everyone and everything, but he eventually realizes he can't win against anyone. Also, the protagonist takes a courtesan as a concubine; he was probably 8 years old at the time.

Li's mother is a major flaw (even in her current state, she still scolds her son; are women in the Tang Dynasty like this? Is this the author's vision of a "bold and unrestrained woman of the Tang Dynasty"), the contracting arrangement is also a flaw (it's understandable to contract when there's no money, but what's the point of continuing to contract after they have money?)

If you don't like it, don't read it, so as not to affect the author's mood while writing.

The opening scene is poisoned to death. A four- or five-year-old jinx's child can understand medical books, cure an illness that even Sun Simiao couldn't cure, and even devise a plan to leave the palace. Are all the other people stupid? Don't they suspect anything?

Good heavens! A modern person went back to ancient times and studied characters for a year, and still can't fully understand them, only able to roughly read some letters... How stupid must this person be?!

What the hell is this? You're used to being a masochist, aren't you? Are you out of your mind?

Are you even going to write it or not? Give me a heads-up, you eunuch!

To be honest, this book is basically not worth reading if it doesn't end with the protagonist establishing himself as emperor overseas.
