A Tunnel Boring Machine Dug Through Ping'an County, and You Call This Tunnel Warfare?

Qin An, an excavator operator, acquires a portal that lets him travel back and forth between the world of Bright Sword and modern reality. He makes a fortune doing business with Li Yunlong, while also sending a steady stream of modern weapons, supplies, and machinery into the world of Bright Sword.

Kong Jie: The excavator starts up, and the trenches are ready in the blink of an eye? Now that's satisfying! Damn, that's satisfying!

Ding Wei: A crane hoists the Japanese blockhouse into the air. Old Qin, that's a brilliant idea!

Sun Desheng: Cavalry company! Bayonets on the front of the tractors! Everybody charge!

Li Yunlong: You dug a tunnel straight to the Japanese command post with a boring machine. Damn, you're a real talent.

Second Battalion Commander Shen Quan: A thousand RPGs firing at once? Those Italian cannons are nothing!

Zhang Dabiao: Enough talk. My AK assault battalion is going to have some fun first...

Xiao Zhong: Nani! Where did all these steel monsters come from? We can't stop them. The Cage Plan can't stop them at all. Find out who this Qin An is, immediately, by any means necessary...
