王一学
要不下次或者线上
@王一学 这样
青天零云 17:03:59
我们
青天零云 17:04:05
线上vp
青天零云 17:04:10
石珈铭
我们有昆明吗
@石珈铭 还没消息
王一学 17:04:13
其实可以
王一学 17:04:44
要不线上vp点别的场
王一学 17:04:48
ecf先留着
青天零云 17:04:54
那就成都
王一学 17:04:57
okk
青天零云 17:05:02
等下
石珈铭 17:05:04
现在吗
青天零云 17:05:05
还没有
青天零云 17:05:08
成都
王一学 17:05:19
ucup上有
青天零云 17:05:19
哈尔滨
青天零云 17:05:25
哦
青天零云 17:05:28
要不哈尔滨
王一学 17:05:29
他们昨天vp了
王一学 17:05:55
王一学
他们昨天vp了
前天
青天零云 17:06:02
王一学
前天
@王一学 因为他们申请了
青天零云 17:06:06
我们没有权限
王一学 17:06:09
哦哦
王一学 17:06:18
那就哈尔滨
王一学 17:08:44
你们一会先开
王一学 17:08:49
我去课上看一眼
青天零云 17:49:07
6.10开始，连麦打
青天零云 17:49:18
我主机
青天零云 17:49:24
代码写完发我
石珈铭 18:03:56
石珈铭 18:03:59
咋进
石珈铭 18:04:14
没入口
