The apocalypse is coming, zombies are spawned every day, and humans are huddled in the base city and lingering. Three major forces are divided: chaebols control resources, counselors play power, and hypocrites hold high the banner of morality. The protagonist was once a forgotten genius and a mad boss who was the king of the underground world. He accidentally awakened the Zerg system and was able to build warrior bugs and flying bugs, crushing everything with sheer numbers. He hides deep in the wasteland and secretly cultivates swarms of insects. He looks calm on the surface, but in fact he is ruthless and sinister. He is as gentle as water in front of women, but smiles in front of his enemies and draws a knife. He can be called a humanoid devil. The Zerg obey his orders, both as a weapon and as a harem - he can control both male and female elements, and has full Neptune attributes. Trading terminals are all over the city, and humans hunt zombies in exchange for weapons, but they don't know that the real master has long been lurking. A Starship Troopers-style war begins, with swarms of soldiers and insects, and flying insects blocking out the sun. The protagonist ascends from the shadows to re-establish order with the swarm of insects.
