Hazure Skill [Doku Mukou] wo Ete Tsuihou Sareta Tenseisha, Tamatama Shindeita SSS Rank no Mamono no Niku (Mou doku) wo Tabetara Cheat Skill wo Teni irete Shimatta

Reincarnated Victor acquires the useless skill [Poison Immunity], which only nullifies poison. His father, who expected him to have a superior skill, and his younger brother, who acquired the [Sword Saint] skill, banish him from the noble family he was born into. Still, he thought it was better than being a puppet of his worthless father, but Victor is attacked by a monster in the forest and falls off a cliff, finding himself in a desperate situation. In a last-ditch effort, he eats the meat of a monster said to be highly poisonous, and—"You have acquired the skill !" It turns out that the useless skill [Poison Immunity] is a cheat ability that allows him to acquire a skill every time he eats monster meat! Freed from the "world's common sense" that each person can only have one skill, Victor continues to grow stronger the more he eats, becoming stronger than anyone can reach!
