There Is Only One Screw Left on the Aircraft Carrier. Can I Fix It?

Chen Mo has a broken family, a gambling father, a studying girl, and a dangerous herself. I took over my family's appliance repair shop early. Provide for your family. He is a school beauty who supports his family at the same time. Until I awakened to the system that everything can be repaired, the painting style suddenly became strange. "Can your repair shop really repair anything?" "Yes." "Can the tank be repaired?" "Yes." "Can battle-damaged fighter planes be repaired?" "Yes." "My aircraft carrier only has one screw left. Can it be repaired?" "You can. But you have to pay more." As time goes by, Chen Mo discovers that his shabby repair shop has turned into a weapons wholesaler that is shocking to everyone, and has been given the important task of leading mankind into the interstellar space? "Nutty." "Don't do it." "I'm just a broken maintenance guy. I only want my wife and children to be on the hot bed. I'm definitely not a weapons wholesaler."
