My brother spoke up: "Everyone, it's late already. Tomorrow morning, Arina needs to wake up early to buy the cake she likes, right?" Her parents remembered that tomorrow was the day the Susue cake would be sold. This cake is only available once a year, so they also advised her to go to sleep early. Just as they were leaving, Lia appeared. Arina immediately confronted her: "Hey, at least you should tell me the identity of each person, right?"

The system replied, "Let me check first." A moment later, Lia spoke up: "Hey, master, we said you would know, but it will cost you 1000 reward points."

As Arina hesitated whether to exchange or not, she heard a "ting ting" sound. Lia then asked: "Master, do you want to exchange?"

Arina thought for a moment. If she exchanged, she would lose 1000 reward points, but if she didn't, the task would be harder to complete. Losing a little wouldn't matter, so she said, "I want to exchange."

The system responded: "You will receive the skill to see the information of each person, along with additional wealth in the real world."

Arina asked in surprise: "But... I..."

Before she could finish, the system continued: "You will also receive wealth in the real world as a gift for exchanging this skill."

Her eyes sparkled like stars as she said, "Thank you so much, system."

Lia mocked her: "Master, you're really insatiable."

She replied, "Alright, I’m going to sleep. I'm too tired."

The system said: "I'm busy too. Have a good night."
