The invincible me is very boring

"Who are you?" A plump middle-aged man said in panic.

"I’m an emotionless killer!”A man wearing a black mask pointed a gun at him.

Bang!

A bullet pierced through the middle-aged man’s chest, and then he took the corpse to exchange for a reward.

Originally, I wanted to be a bounty hunter like this, but because I exploited a loophole in the system, I suddenly earned money and became a strong person in an instant. However, after becoming a strong person, I was bored. I just stayed at home and didn’t know what to do. In the end, I built a village to kill time.
