Everything I Spend Comes Back Tenfold

Top student Zhang Zheng catches his girlfriend cheating while working part-time as a food delivery rider. In despair, he unexpectedly activates a System that returns ten times whatever he spends.

“Keep shopping, keep earning it back. Becoming the richest man in the world is within reach!”

“Wait, this System can exchange points for superpowers too? X-ray vision, miracle healing, martial arts..."

Good heavens, being this rich is such a headache.
