Billionaire Legacy: I Became Overpowered With My Spending System

Logan Mercer, an orphan barely surviving on his own, awakened the Spending System as a child.
But as a broke teenager struggling to even pay his rent, how could he possibly use it?

Bullied by his classmates and cast aside by society, Logan’s life changed the day he was suddenly surrounded by men in black suits.

“Your father has been missing for over a year. As per his will, you are to inherit all his assets,” they said.

To his shock, Logan learns that he was the sole heir of the Mercer family fortune — and with it came control of major businesses, unimaginable wealth... and the constant threat of his father’s competitors.

“System, redeem one billion dollars,” Logan said.
