After getting to know Du Lai, who was not friend or foe, they went to the notice board in People's Square.

The sign has a large map of the city, which shows the game areas around the city, and in the middle of the red, the registration office, the supply office, the exchange office, and the headquarters known as the organization.

A registry office is a place where residents are registered.

The Supplies Division is a place where supplies are collected and distributed.

The Exchange Office is a place where you can exchange items for a leave slip.

Among them, the exchange office is the most popular. In addition to redeeming leave slips here, everyone has slowly extended new functions, such as exchanging props or finding someone to form a team.

Because the people who come here have props in their hands.

And those who have props in their hands are people with some ability, which is much better than the chaos of fish and dragons in the square.

Yan Qingwen walked around, had a general understanding of the situation, and prepared to go home.

Bai Youwei didn't want to leave, she looked around with great interest, and asked Teacher Cheng to stop a staff member and ask if there was a place to exchange puzzles.

Lu Ang, who was not far away, was dumbfounded and asked Yan Qingwen in a low voice: "Should she want to collect puzzles here?" ”

Ever since Bai Youwei was about to leave their five puzzles, they knew what Bai Youwei wanted to do.

But isn't it a bit ...... this place, blatantly collecting puzzles? Too attention-grabbing?

Yan Qingwen pondered for a moment and said, "Let's go over too, since we brought people out, we must also send them back safe and sound." ”

Yan Qingwen and Lu Ang walked over.

Zhu Shu thought about it and followed.

As soon as he took two steps closer, he heard two people nearby complaining:

"Uncle, how can someone change the puzzle pieces? Puzzles can be exempted from a doll game, which is better than asking for a leave of absence! ”

"Yes, even if the organization opens the channel for the exchange of puzzles, it is impossible for anyone to change it."

Cheng Weicai hurriedly explained: "We can change the used puzzle pieces. ”

"Used puzzles?" The two people who spoke looked at each other and asked Cheng Weicai, "What do you want to use the puzzle pieces for?" ”

"You don't have to worry about that." Bai Youwei said lightly, "Let's just say whether to change it or not." You reacted so much when you heard the puzzle, you should have the puzzle in your hand, right? Or maybe you know a friend with a puzzle in their hands? ”

The two looked at Bai Youwei with a vigilant face, "...... Even if it's a used puzzle, it's still a puzzle, maybe there is a hidden use that we don't know, so why exchange it with you? ”

"I have props." Bai Youwei smiled, "You guys have been squatting here for so long, don't you just want to change props?" Why, my props are not easy to use, and I want to exchange them with others? I can exchange it with you~ As long as you give me the puzzle, you can get props, it's a good deal, isn't it? ”

As she spoke, more and more people gathered nearby, looking at Bai Youwei and Cheng Weicai curiously or suspiciously.

Everyone has seen changing food, changing medicines, and props for props is also common, but I have never seen a puzzle change.

Yan Qingwen frowned, and led Lu Ang and Zhu Shu to stand beside Bai Youwei, so as not to make these people think that an old man and a cripple were easy to bully.

Lu Ang lowered his voice and said in his ear: "This girl can really go crazy, she dares to make trouble in such a place without even bringing a rabbit, and only Shen Mo can stand her." ”

Yan Qingwen curled the corners of his lips when he heard this, he didn't make a sound, his eyes moved slightly, but he saw a familiar face.

“…… It's the guy just now. ”

Lu Ang was slightly stunned, looked into the distance, and saw that the young man named Du Lai was also in the crowd.

Du Lai was staring at Bai Youwei intently, as if he was curious about what props she would come up with.

Seeing that there were more and more onlookers, the staff of the exchange office was worried that something would go wrong, and said to Bai Youwei: "Any transaction needs to write a notice, write it and post it on the transaction column, and the exchange office does not assume any responsibility for the private transaction between the two parties." ”
