Chen Miao transmigrated to a supernatural world, where everyone had their own profession, such as “Student”, “Fighter”, “Thief”, and so on.After much contemplation, he activated the “Gunslinger” profession.From then on!While the foreign races brandished their claws to invade, and others tirelessly trained their physical fitness and learned skills.Chen Miao silently ventured into secret realms to collect all sorts of materials, crafting Occupation Exclusive weapons like the “Thompson Submachine Gun,” “Falling Blossom Sniper Rifle,” “Inferno Gatling,” “Matrix Sky-Eye Cannon,” and so on....One day, people suddenly noticed that a very unfamiliar Supernatural Occupation had appeared on the city's Combat Power rankings.And in the crowd.Chen Miao, bare-chested under a black suit jacket with sunglasses on and a cigar in his mouth, held two Inferno Gatlings in his hands, looking up slightly at a group of scoundrels in front of him with the corners of his mouth turned up.“Don't wait for me to stuff the gun barrel in your mouth before you admit you were wrong.”

The empire has turned into the land of the undead due to a spell gone wrong. God summoned heroes from countless worlds to purify the empire and plant new hope. Lee Shin Woo, an ordinary earthling, was also summoned. As an undead, that is.
