Chen Feng's hardware store accidentally connected to the end of the world, and he received an incredible order to repair tanks at the beginning. He discovered that the hardware store can not only repair modern equipment, but also exchange or transform apocalyptic materials to create various sci-fi weapons, ranging from cold weapons to future energy cannons. With this unique ability, Chen Feng quickly rose to become the only arms supplier that all the major forces in the apocalypse are vying to curry favor with. He skillfully dealt with the tide of zombies, mutant beasts and human infighting. Every arms transaction was accompanied by bloody conflicts and huge profits, and finally established an apocalyptic empire with arms as its core, dominating the world.
