Both of those people had fought with the chief-outer court disciple of the 'Imperial Mandate sect' and none of them lost in a head-on fight?
Every single person at the peak of the mountain had already passed the fifth trial to get here, so they all knew how terrifying that purple-robed youth actually was.
Even if they put aside his cultivation that had already entered the next major realm, making him an early-stage Dao Emperor for these Dao Kings and an early Sovereign realm cultivator for the Dao Emperors, it was still a fact that the chief of outer court disciples was also a genius who had comprehended an extremely powerful supreme Dao!
He wasn't someone the majority of these cultivators could even hope to escape from, let alone fight head-on like that! Therefore, accepting that Shun Long and the golden-robed young man had each dealt with him in such an overbearing manner was more than a simple blow to these cultivators' egos.
