Lu Wanwan recognized the card, not because she knew Gu Annan's card, but because she recognized the exclusive black card from the Holy Covenant Bank.
The world's most renowned international bank, the highest-end credit card possible, only obtainable by personal invitation from the bank president and not by application from just anyone. There's no spending limit; it can even act as an entry token at some famous international galas, where it serves as an implicitly accepted invitation.
Unlike the long string of numbers on ordinary cards, this one had only five.
Most people would think, "Are you kidding me? Can this thing with a five-digit number even handle transactions?"
However, the usual bearers of such a card wouldn't risk misplacing it by using it at places too low-end, leading to confused stares from the clerks as if they were insane.
Lu Wanwan was well aware of the card's significance because her mother once had one, too. Yet she had only seen it, never used it herself.
