Hazure Skill “kinomi Master”

Light was a boy who dreamed of becoming an adventurer. He went to the temple with his childhood friend to get a skill fruit. While his childhood friend got the rare Sword Saint skill, Light obtained the Nut Master skill which only improves farming ability. Light is forced to abandon his dream of becoming an adventurer to start working as a farmer. Although warned to never eat a second skill fruit because he will get poisoned and died, Light’s unique skill allows him to eat as many skill fruits as he wants to obtain multiple skills.

Then he gets OP powers and a harem.
