In total, he has visited four of the Five Realms. So far I haven't heard any news from Cang Wei. If the plane Cang Wei arrived in was not the Five Tai Realm, then only Xuanhuang Tianwai Tian could find out about him. There are many planes adjacent to Xuanhuang Tianwaitian, so it is normal for Cang Wei not to be in the Wutai Realm....
