I Just Want to Fix My Castle

[Please add my upcoming novel to your reading list! The neighboring novel, "Kicked Out by Everyone, I Reached the Peak of Life," is a sweet Western fantasy story. I won't drop it or leave it unfinished!]

After transmigrating as Oravilla, he discovered just how hard life could be for a down-and-out noble. He looked over what he'd inherited: an earl's title, a few servants, a small fief, and a dilapidated castle.

A shabby garden, leaky rooms, and dim candlelight. Fixing up the castle and improving his quality of life were now the most important things. But he faced one major problem: he had no money!

Before he could even figure out how to earn money, a group of adventurers invaded the castle. He watched as the flower trellis he'd worked so hard to repair was knocked down. Just as his body hit the floor, a voice rang in his head: "Ding! The old castle has been registered as a new dungeon. New boss, the Bloodstained Earl, is about to enter a berserk state."

Wait! I just want to fix up my castle. I don't want to be a boss! Adventurers keep pouring in, and those are my newly restored statues and my brand-new piano. Could you at least hit them a little less hard?

Today's castle renovation progress: -10%.

Hartred was lucky enough to get an ability when he entered the game: he could see NPCs' inner thoughts and affection levels.

He looked at the newly unlocked dungeon and the boss sitting on the throne, speaking his lines with cool composure.

A line of text popped up in the prompt box beside him: "Please, aim your magic properly! Don't smash the wall lamp in the corner. It cost me five silver coins!"

Not understanding what was going on, Hartred tentatively threw a fireball at the corner. A huge dialogue box immediately blocked his view. "QAQ!" It was so distracting it hurt his eyes.

The boss before him still maintained an elegant, calm demeanor, so Hartred thought his ability might be malfunctioning. As the dialogue box slowly disappeared, he finally saw the boss's name: the Bloodstained Earl, Oravilla.

Things were getting interesting.
