The Divine Spear Secures the Great Ming

He transmigrates to the late Ming with a Glock pistol as a bonus.

It has only fifty-one bullets left.

The first bullet takes down a thug attacking someone in the street.

The fiftieth pierces the chest of a Later Jin prince.

The fifty-first...

Jiang Yuan has never forgotten that the bullets will eventually run out. So before the gunfire stops, he must conquer the entire realm.
