After the college entrance exam, Chen Wanyu became bound to a tycoon-in-training System.
The System gives her money, refunds her after she spends it, and rewards her with various skill cards and technology fragments.
So she spends an absurd amount of pocket money and gets tenfold cashback, while learning all kinds of skills to improve herself and picking up various rewards along the way.
With these rewards, Chen Wanyu helps everyone in the country whiten their skin, grow their hair, lose weight, and sleep peacefully.

When holographic technology is unveiled, the whole country is in an uproar!
Only when the world undergoes a great upheaval does she learn that this was the real reason the System arrived!
