Fury
Those who had arrived this deep in the wastelands this quickly were all towards the top of their sects in power, and had experienced many things, but even they were chilled by the display before them.
There were quite a few Heavenly Lightning Sect disciples in the crowd as well, but they were all in the Qi Condensation Realm. If someone like Russell, who was in the Core Formation Realm was killed with such ease, they did not want to speak out and make themselves a target as well. They felt rage for Russell's death, as well as shame in themselves for not having the resolve to speak up to the group of Bloodfiend Sect youths.
It was known to all of them that Russell had a lifeline in the spatial talisman, and somehow he still ended up dying. This alone showed that the person who had killed him, one of the Three Emperors of the Bloodfiend Sect, had incredible power.
