Global Class Change: Bound to the Campus Belle, Rewards Returned a Thousandfold

I changed classes to Blue Fist and activated the Ten-Thousandfold Cashback System.

Following the System's instructions, I bound myself to the campus belle.

Whenever she improves, I get an increase multiplied by a certain amount.

"Ding! The campus belle gained one skill point. The Host receives ten skill points in return!"

"Ding! The campus belle gained one free point for her four core attributes. The Host receives one hundred free points for his four core attributes in return!"

"Ding! The campus belle obtained a pink-grade divine weapon. The Host receives an orange-grade legendary weapon in return!"

"Ding! The campus belle's skill level increased by one. The Host's skill is instantly raised to its maximum level in return!"

Little by little, my Blue Fist becomes so powerful that I can knock out every opponent with one punch.
