The First Strategist

A modern military chemical engineering expert is reborn in ancient times. Black powder is only good for fireworks? Not a chance. A few improvements will make the enemy tremble in fear.

A bandit shouts, "I have a treasured blade that can slice through iron like mud!"

Yang Huan gives him a contemptuous look. "Come on, let's see whether your blade is sharper than my kitchen knife."

What? You're the number one hidden-weapon expert in Great Qian? See what I'm holding?

It's called a gun.
