The Three Kingdoms at the End of Han Dynasty? Warhammer Three Kingdoms!

[Slightly sandy] + [Invincible Style] + [No Knife] Yuan Yao traveled to the world of Warhammer 40k and served as a political commissar for fifty years, and then traveled back again. The good news is, he became the prince and his father died. The bad news is that his emperor father's name is Yuan Shu. However, Yuan Yao was not very desperate, because he discovered that his system's golden finger could be used to redeem the Astra Militarum with military exploits! Just when he was thinking about using the Astra Militarum to overwhelm the most powerful man in the second century AD, the Emperor sent him a message: The evil god of warp has invaded the Three Kingdoms of the late Han Dynasty! (I don't know whether this book is a fan of Warhammer or a fan of Three Kingdoms...)
