The Overpowered, Domineering Son-in-Law

He wrote a System for himself, but it took being pushed to the brink before he realized just how terrifyingly powerful it was.

From the start, his girlfriend's family rejected him, and her father even wanted to bury him in the tidal flats. Why shouldn't he strike back with authority?

When people mocked his background, he boldly spent tens of billions to buy seven precious accessories. The money was only an advance on his earnings for the next two years.

His abilities grew stronger and stronger, and he kept improving the System. He sincerely pursued love, and even when countless beautiful women chased after him, he never forgot his original intentions.

If he doesn't stand up for himself, he'll let himself down, and his beloved woman even more. He'll use his strength to win her heart and earn her parents' blessing.
