TENSEI KENJA WA MUSUME TO KURASU

Tensei Kenja wa Musume to Kurasu summary:

Meet Kento Oonari, salaryman in hell.
Overworked by his bosses, his head surely whirled.
He dies, but meets up with a god called Raidel
Who tells him that he’ll be sent to a new world.
Kento's fairly cautious - he’s read this before.  
And so, to the god, he begs for one thing:
“I just want to live a slow life, nothing more.
“Just give me a house and a skill for farming.”
So Kento is sent to a medieval age
To live a nice, slow life. But what a surprise!
The god gave him the powers of a Great Sage!
And Kento used magic in front of commoner eyes!
So join us today, as we read of this man:
His cheat skills, his slow life, and his little girl clan.Original WN: https://ncode.syosetu.com/n4302es/
