Given Lu Xuan's current status, only elders or grand elders were considered worthy of personally getting in touch with him. The lowest of status among those who met him had to have been the best among the younger generations. One such example was Shi Buyi, who was definitely destined to be among the best to be found in the world.
They were all at the very top of the world; they could easily handle any problem regarding cultivation that they ran into. In contrast, everyone else would've deemed such problems to have been quite a headache to handle.
However, none of these problems were much trouble for Lu Xuan, who could basically solve any problem that he encountered with ease.
It would usually take several lines or even just a single line from Lu Xuan to get to the gist, enabling those who came to him to find their way out right away.
There was no doubt that all the problems that they brought before Lu Xuan had plagued them for quite some time now.
