The Heavenly Demon Does Home Repairs

The greatest martial artist of all time, the Heavenly Demon, crash-lands on Earth, now overrun by dungeons.
His thousand-year internal energy is gone, and he has no way of returning.
To make matters worse, the girl in front of him is yelling at him to pay for damages.
“Because of you, I can’t receive divine blessings! What are you going to do about it?”
In the end, the Heavenly Demon ends up getting a job at the mysterious ‘Bokbok Interiors.’
“I’ll take responsibility. But in my own way.”
