Card War: I Turned a Trash Card into a Nuke

After transmigrating to a card-based otherworld, Yi Yun gets hit by a surprise attack and blasted off the map from the start. After three days without food, all he can think about is making money and staying alive.

Other people need a dust-free workshop and incense and a ritual bath to modify cards. He uses rusty pliers to blindly cut a bomb's fuse.

Other people pursue higher-dimensional laws. By chance, he gets his hands on an ancient military-industrial black card, then uses the tricks of a slum electrician to turn a useless one-star card into a tactical flash grenade!

Faced with enemy heavy armor and war behemoths filling the sky, what can he do?

Yi Yun, who suffers from terminal firepower deficiency syndrome, goes all out and launches a completely insane assembly line for mass-producing cheap troops.

"This low-level card has a contact-triggered short-circuit fuse. Touch it and you're dead."

This is the story of a poor man who uses hardcore military-industrial modifications to upgrade shoddy homemade bombs into Abyssal Nuclear Blast Cards, sweeping across the world with a storm of cheap artillery fire.
