Bright Sword: I Handcraft Cannons, and Okamura Yasuji Breaks Down

In 2023, mechanical genius Liu Chunyi transmigrates through an explosion at an arms factory into the world of Drawing Sword in 1940, and awakens the Military Industry Black Tech System.

Li Yunlong, do you believe I can cut rifling with a stone mill?

He doubles the range of grenades made in the border region, uses bicycle chains to make machine-gun belts, and turns gasoline drums into 107 mm rocket launchers. Japanese military experts are so furious they nearly spit blood: Why do the Eighth Route Army have rapid-fire cannons?

The Battle of Ping'an Gler turns into a fireworks display. Yamamoto's Special Forces step on glass landmines, and Chu Yunfei trades American howitzers for technical manuals. When Liu Chunyi makes nitroglycerin out of fertilizer, even the brigade commander trembles: Get this menace to headquarters, now!

What's the rush? He grins and unfolds a map of Tokyo. Wait until I send Okamura Yasuji a package.
