The Great Qing Master's Dead End in the Western Han Dynasty

My name is Lao Ma, a famous criminal master during the Daoguang period of the Qing Dynasty. I have never passed the merit examination, I don't know how to make glass, and I don't know how to prepare gunpowder. I have lived in this world for forty years, and I have only figured out one thing: how to even the dead and squeeze out the living in the cannibalistic officialdom. I closed and opened my eyes, and I was thrown to the border of the Han Dynasty two thousand years ago.
