Victor, a reincarnated person, obtained the skill 【Poison Nullification】, a dud Skill that can only neutralize poison. Expecting a superior Skill, his father, along with his younger brother who obtained the 【Sword Saint】 Skill, exiled him from the noble family he was born into. Victor thought it was better than being a puppet to his trashy father, but he was attacked by monsters in the forest and fell off a cliff, finding himself in a desperate situation. In a gamble, he ate monster meat said to be highly toxic and── "Obtained the Skill <<Zettenken>>". It turns out that the dud Skill 【Poison Nullification】 is a Cheat ability that allows him to gain a Skill every time he eats monster meat! Freed from the "common sense of the world" where each person has only one Skill, Victor continues to grow the more he eats, becoming stronger until he is beyond anyone's reach──!!
