Reincarnated Lord: I Really Don't Want to Work Hard Anymore

[Time travel + no system + lord + all-powerful male protagonist + Western fantasy + slow burn]

Having transmigrated to a world of swords and magic, I originally thought I could inherit the lord's land and live a life of luxury.

But the world is often fair; while opening one window, God will close another door for you.

He was supposed to inherit the title of marquis right from the start, but the territory he inherited was about to be annexed.

Despite coming from a family of magicians, he lacks magical talent and can only serve as a knight.

Despite being a lord, he chooses to become an adventurer, fighting monsters and leveling up.

Okay, okay, so this is how you arrange people, right?

I'm done. Let whoever wants to do it do it.

......

Of course, the above talk about giving up was a joke.

Although I want to give up, I've only had one chance to start over, so I'll give it my all this time.

Wait, what? I still have a main storyline? No way! My leisurely life in another world is over!
