After they entered the Aricus Underground Ruins, those from Netherspirit's Claw no longer showed up to disturb and stall Qin Ruo's party. Firstly, they had received news that Buttcold was defeated fair and square; secondly, they were deterred by Slayer's Heart and the Bauhinia League's long-developed prestige.
Buttcold and Altos were both high-rank officers in the Netherspirit's Claw Hunter Troop. If even they failed, what chance did the others have? The League members no longer doubted the authenticity in all those forum threads, and they recognized that Qin Ruo was as powerful as the rumors said.
As for the other four Clans, there was nothing they could do. Unlike the Netherspirit's Claw Hunter Troop, they could not do as they pleased since they still had to show some degree of respect to Bauhinia Clan. Frankly speaking, those players who loitered around the area were all too familiar with Slayer's Heart's capability to mess with him.
