Isekai de Tochi wo Katte Noujou wo Tsukurou

Norio, a corporate drone in modern Japan, is summoned to a fantasy world to fight evil! But it turns out that the magical ability he got doesn't work?! Thankfully, he has a plan B. Ask for a plot of land to cultivate a farm! To his surprise, that supposedly useless magic ability turbo charges his tools, allowing him to craft with wood like a master and plant vast fields of crops. After fishing up a mermaid wife, charming a lich, and tempting a young dragon over to his side with home cooking, there's nothing our hero can't do!
