Everything in the world carries resentment. When resentment takes shape, it becomes a vengeful spirit that wreaks havoc on society. The human race has produced object controllers to suppress these resentful forces. Transmigrated into this world, Huo Lang only wants to be an utterly ordinary nobody in the martial world. But step by step, he is forced to uncover the conspiracy behind the world. Others: “A Gatling gun, a huge sword.” Huo Lang, meanwhile, simply whips out his “General Store System.” I've got everything here! It's just a little strange. What kind of protagonist uses balloons as weapons and a helmet for defense? (Other authors rack their brains writing novels. This one is like a pig: “Go on! Who needs all those rules!”)
