Chapitre 1043: Crystal card and selfishness (1)

Zhao Hai had thought of a few methods before, but none of them worked. It was only recently, when he was cleaning up the space, that he realized that there was such a thing on the continent, a crystal card!

Back on the ark continent, Zhao Hai had obtained quite a few crystal cards. However, crystal cards were not of much use in the realm. After the realm was upgraded a few times, crystal cards could be used. The realm could convert the money in the crystal card into money in the realm, or deposit the money in the realm into the crystal card. Therefore, there were many bank-like things in the ark now, and crystal cards had become a necessity for everyone in the ark.

On earth, you could use your bank card, but there were certain problems when you thought about going abroad. You could lose it, be stolen, or be hacked. However, there would never be such a problem in the space.
