I Handed Over the Two-Way Portal from the Start, and the Nation Helped Me Fight the War

[Power fantasy + Steamrolling everything in the later chapters + Drawing Sword + Crossovers with various worlds + Yan Shuangying + The state takes action + Sci-fi technology]

One day, a strange man showed up at the police station. It was none other than Chen Mo.

It turned out Chen Mo had unlocked the Dual-World Travel Selection System, and had just returned from Cangyun Ridge in Drawing Sword.

The two police officers didn't believe him.

So Chen Mo immediately took them to the world of Drawing Sword. And with that, the state took action.

Li Yunlong: “Good heavens! What is that enormous chimney?”

Kong Jie: “Now that's satisfying! This is what I call satisfying! Look at them firing shells as if they cost nothing.”

Brigadier Chen: “Damn, compared to them, we're beggars.”

Chu Yunfei: “Who would have thought? This unit really has cooked up a pot of steel meat stew!”

Guess how long the Japanese invaders will need to escape China.

Afterward, China has the resources of an entire universe to serve as a springboard for its rise.
