Liangjian: I Rubbed the Cannon with My Hands, and Neji Okamura Cried.

In 2023, mechanical genius Liu Chunyi traveled to the world of swordsmanship in 1940 during an explosion in an arsenal, awakening the black technology system of the military industry. Li Yunlong, do you believe I can carve rifling with a stone grinder? He doubled the range of hand grenades made in the border area, used bicycle chains to make machine gun bullet chains, and transformed gasoline barrels into 107 rocket launchers. Japanese experts vomited blood: Why did the Eighth Route Army have rapid-fire artillery? The Battle of Pinangrad turned into a fireworks show, Yamamoto's special agent team stepped on a glass mine, and Chu Yunfei exchanged an American howitzer for a technical manual. When Liu Chunyi used chemical fertilizer to create nitroglycerin, even the brigade commander trembled: Send this monster to the headquarters quickly! What's the rush? He smiled and unfolded the Tokyo battle map, waiting for me to send a courier to Okamura Neji. This novel and its characters are purely fictitious.
