War of Resistance: I asked you to repair your gun. What the hell is Flying Thunder Cannon?

Shen Feng traveled through the Anti-Japanese War and became a fresh graduate. He was even assigned to the border arsenal.

Awakened the Divine Mechanic System!

He went to report to the Munitions Factory and passed by the Gray Cloud Ridge, but was caught by Li Yun Long as a spy.

After knowing Shen Feng’s identity, Li Yun Long was very disdainful of this pale-faced scholar.

However, he did not expect Shen Feng to create a great killing machine on the spot-the heartless cannon!

Caliber is justice, and the size of my caliber depends on the thickness of the gasoline barrel!

The moment the cannon sounded, the Sakata United Army wailed in pain. The command center was blown up on the spot!

Brigadier General: A 60cm caliber mortar?!

Boss: This kid is really a talent. I want him to be the factory manager!

Old Li: " Brother Shen, I was wrong. I beg you, please give me two more shots!"
