I found it by accident when I was looking for a friend on Afu. I saw it when I was doing the task, and now I am parked in the mysterious lake! But can you join my dream class? The class number is 96627 150, which is on the second page of the class list! Welcome to join us ~ My name is Hi ~ Qing Xue, and I often hang out at 10. Mushroom Cave and Moore Football Stadium.
