Card War: I Changed Useless Cards into Nuclear Bombs

Traveling through a different world of cards, I was brutally attacked by a blitz at the beginning. Yi Yun, who had been hungry for three days, could only think about making money and survival. Others needed to burn incense and bathe in the dust-free workshop to repair the card, but he used rusty pliers to blindly cut the bomb fuse. While others were pursuing high-dimensional laws, he accidentally took out an ancient military black card and used the techniques of a black electrician in the slums to change the one-star waste card explosion into a tactical flash bomb! Facing enemy heavy armor and war beasts flying in the sky? Yi Yun, who was in the advanced stage of the phobia of insufficient firepower, completely launched a frenzied assembly line of cheap troops. "This low-level cassette contacts the short-circuit fuse. If you touch it, you will die." This is the story of a poor man who relied on hard-core military-industrial magic modifications to upgrade inferior home-made bombs into Tianyuan nuclear explosion cards, and used cheap artillery to destroy the world.
