You’re an Arms Dealer, So How Come You Have Cutting-Edge Technology?

Lin Han transmigrated to a parallel world and became the world's largest underground arms dealer. Then, one day, Lin Han's domestic operations were exposed, and an international organization arrived to investigate. Ultra-quiet drones; radar-blocking paint; intelligent nanorobots; carbon-fiber exoskeletons... "And you still say these aren't weapons? They're even more powerful than weapons!" One piece of cutting-edge technology after another left the American representative trembling in fear. Just then, a certain country came under terrorist attack. At the critical moment, Lin Han led his people onto the battlefield, and the terrified terrorists immediately ceased fire. "In front of Lin Han, terrorists are as obedient as kittens." "He's obviously our guardian angel." "How could an arms dealer be this handsome? He must be my husband." As more information came to light, everyone discovered that arms dealer was only one of Lin Han's many identities. "You're so talented. Why become an arms dealer?" Lin Han gave a faint smile. "Just something I do for fun. My real dream is nuclear peace." The entire internet: World peace?
