As the vast desert forbade flying and could not use talismans, the method of transmitting messages was very primitive, which was to rely on human strength or spirit beasts.
However, fortunately, the speed of the cultivators was not slow. In less than an hour, the disciple on duty who went to deliver the message came back, and he also brought an old acquaintance of Yun chujiu -- Mountain Masster Zhuo of the primordial chaos sect.
The reason why the Allied army sent Mountain Masster Zhuo over was that although the unaffiliated cultivator alliance was a newly emerged organization, it was still considered a medium-sized force. The Allied army still had to give some face to it, therefore, they sent mountain masster Zhuo, who had a high status, to personally welcome him.
