He explained to his sister, "A crystal card is a palm-sized card made of crystal, the same material as a crystal coin."

"The front is the ID card, which contains various information such as name, age, place of birth, card number, etc."

"The back can be used to send messages, make remote calls, and even store money."

"Having a crystal card is equivalent to having a formal identity; otherwise, you're an unregistered person."

"It's fortunate that we came to Bright City. If we had gone to a city under the jurisdiction of the aristocratic alliance, we would have been treated as refugees and wouldn't have been able to enter the city gates."

Shui Qingqing listened, completely stunned.

Shui Duoduo continued, "The Thorn City where we used to live was a small border town where crystal cards were basically unnecessary. Moreover, there were no World Bank branches there, so even if we wanted to apply for one, we couldn't."

"But it's different when you come to Bright City. You need crystal cards for many things, and you can't do anything without them."

Shui Qingqing hesitated and asked, "Won't the crystal card be very expensive?"

Shui Duoduo: "Not expensive, 10 crystal coins each."

Shui Qingqing whispered, "This isn't expensive at all. Maybe I shouldn't get one. You can just get one for Duoduo."

Shui Duoduo: "Sis, didn't you hear what Sister Lily said? She took us to do it, so of course she paid for it, right, Sister Lily?"

He looked at Xin Sui with a hint of mockery in his expression. Where was the cautious and naive poor boy he had pretended to be at the beginning?

Xin Sui glanced at him. Was the male lead no longer pretending in front of her?

He probably already guessed that she had "predicted" his rebirth.

Both of them were aware of this, but tacitly refrained from making it explicit.

"Yes, that's right. I'll pay for it. Anyway, Duoduo will earn it back for me later, right?"

Shui Duoduo: "...Of course."
