“You useless worthless fool! I cared for you for so many years yet—you have [Farmer] and a skill called [Poison Resistance]!? What a disgrace!” The ritual taken at the age of 15- [Heaven’s Blessing]. Under that, I was given the job [Farmer] and skill [Poison Resistance]. Though born in a famed noble house of swordsmen, Under the heap of ab*ses and shouts, I had my seat as the inheritor to the house taken away and exiled from my house by my father. At loss, and with no future in sight—-It was revealed that the skill [Poison Resistance] was actually [Null Poison]. And then, an encounter with an ancient book; I would come to learn the usefulness of my skill. Yes, what was considered a waste skill, [Null Poison], was actually a strong skill that could quite literally nullify “any” kind of poisonous substance.
