They had all the reasons to be shocked by Roan's skills. First of all, the number of Foundation Establishment cultivators that can really use skills at Roan's level is minimal. Usually, those are descendants of prominent old families and clans with hundreds if not thousands of years of history. As mentioned before, skills for Foundation Establishment are extremely rare.
Another thing is Roan's background. Hulian had made sure to check it and knew that he came from a small tribe. There is no doubt that a place like that wouldn't have skills for Foundation Establishment cultivators. In fact, they wouldn't even have for Core Formation either.
Hulian couldn't help but send Alanda a Spiritual Sense message.
"Just where did he learn that skill? The level that he displayed far surpassed anything that I know. Not to mention that I have never seen that skill before."
Alanda smiled before answering.
