Blood Heir's Retribution,You Maxed Out the Wrong Black Card

For the three years I was studying abroad, the black card with no spending limit that I left for my son was maxed out every single month.

At first, I told him that as long as he spent more than five million a month, I’d grant him any wish.

As time went on, the card kept exceeding its limit, but he never made a single request.

Every alert I got was either a luxury sports car every three days, a private estate every five days, or even more ridiculous, ninety-nine adult toys.

I thought as long as my boy was happy spending money, I didn't care what weird hobbies he had.
