Bright Sword: The Time-Traveling Arms Dealer

Gu Cheng transmigrates with an arms-dealer System into the world of Bright Sword. The System requires him to designate troops to kill Japanese invaders for points, which can be exchanged for everything from rifle ammunition to infantry guns. "Commander Li, want some ZB vz. 26s?" "Want some rocket launchers?" "Yes. All of it." At that moment, the highest-ranking commander in Taiyuan looks horrified. "Baka! Where did these stupid Eighth Route soldiers get so many advanced weapons?" P.S. The poor fight with tactical maneuvers. The rich, blast them to hell.
