Invincible Heroes: My Castle Will Be Upgraded

I, Lin Yi, an ordinary otaku in the 21st century, am standing in front of a crumbling castle, looking at the translucent system panel in front of me, the corners of my mouth twitching. My career as a lord has officially begun. Although there is only a broken castle at the beginning, I believe that with my wisdom and... Ahem, a little bit of luck, I will be able to make my way in this world! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
