This wasn't the first time Azura Xalthor approached the entire group with seething fury. However, it was a rare occurrence so even until now, the Heroes of Relics weren't used to that side of his personality.
As Sun Wu was brought back to reality, he stood up and stole a glance at the other Heroes of Relics who simply didn't want any part in the matter. They all looked away as if to indirectly tell Sun Wu to deal with the guild master by himself.
Although the guild master didn't mention anything regarding his fury, everyone in the Heroes of Relics already knew what it was. After all, the only reason why Azura Xalthor displayed such wrath was because of a decision they made a couple of weeks ago. This decision didn't have Azura's second opinion, hence his fury.
