I Own a Story Tavern

From the start, he gets a story tavern and sets off on an invincible path!

What? I'm just a tavern owner without much money?

Sorry, my money goes on forever!

Aliens are invading Earth?

They'd better check whether I'm still on Earth before they try invading!

The Cosmic Empire wants to blockade the Solar System?

Then I'll beat them until they wouldn't dare blockade it!

The early story is calm, but later it turns into an invincible power fantasy!

I'm a new author, so please be patient with me!
