Conversations with Ancient Emperors, Starting with Qin Shi Huang

Qin Yan, a male streamer, gains the ability to transmigrate through time and speak with emperors of the past. So he goes and gets under every emperor's skin.

Qin Shi Huang: You're saying the army of Huaxia in 2,000 years can wipe out my million-strong army in the blink of an eye? Impossible. Absolutely impossible.

Cixi: You have some nerve calling me an old witch and saying I'm a sinner in history! You're talking nonsense.

Cao Cao: What? People in later generations call me the traitorous Cao? They say I have a thing for other men's wives?

Puyi: You're saying the palace maids ruined my body when I was a child, and that I'm impotent? That's bullshit.

Zhu Yuanzhang: What? My Great Ming was destroyed by Chongzhen?

Yang Jian: What? You're saying my son Guang killed his father and usurped the throne? Impossible. Absolutely impossible.

(This book is a real blast. The protagonist talks with nearly every famous emperor in Chinese history.)
