The Transmigrating Veteran

A battle-hardened veteran dies of old age, arrives in another world, opens a small restaurant, and hopes to live a quiet life.

But the busted, broken System he carries around doesn't want him to settle down. It says, "Quiet life, my foot. Let's get this party started!"

Dragging that nuisance along, he transmigrates between worlds and causes trouble everywhere, completing all sorts of ridiculous missions issued by the useless System.

Protagonist: "I want to live a quiet life!"

System: "No, you can't!"
