Kapitel 1220: Chapter 1218: What do you mean by this?

Truth be told, Ren Feifan had never seen the black card in his hand before, but Du Jiang had whispered a few words in his ear, instantly giving him the instructions he needed.

Following Du Jiang's method, Ren Feifan pinched his fingers into a gesture and pressed them onto the black card. He instantly saw a series of numbers emerge on the dark card, precisely 150,000.

The woman in green explained on the side, "My lord, this card can be used to purchase items in any shop in this area, and of course, if you want to exchange it for Hidden Stones, that's also possible, though it is somewhat cumbersome. The card can also be used for face-to-face transactions. This is something we developed based on some mundane items."

Ren Feifan suddenly understood — this bank card was somewhat similar to the Alipay and WeChat used outside, quite convenient.
