Wait, You Call That Steel Fortress a Shield?

Targeted by jealous people, Ye Fan could only take a job maintaining weapons for a border defense unit. The place was in dire need of work, with all kinds of outdated weapons scattered around.

The captain laughed awkwardly. "Just fix them up so they're usable."

An ordinary dagger was transformed into a super combat knife that could slice through iron like mud, and even pierce a tank.

An automatic rifle was converted into a compressed-air rifle, breaking through industry barriers and turning the world order upside down.

The United States decided it couldn't let Ye Fan keep developing, and sent a commando team to attack the border of Jiuzhou.

Commando team: "Oh my God, what is this steel fortress?"

Ye Fan: "It's just a shield. What's the big deal?"
