Killing off a man just because his foot had been stepped on; such a farfetched yet tyrannical reason was not very convincing to others. The quick-witted players at Ray's Bar could naturally tell that Gu Fei was just looking for a reason to eliminate the man.
Furthermore, Gu Fei's current execution of his moves was far more vicious than his execution of them before. With his attack connecting to the target better and Silver Moon's lackey being weaker than the guild leader moments ago, Gu Fei managed to finish the man off with that one strike powered by Twin Incineration.
"How domineering!" all the leaders exclaimed in unison. Still, they could not fathom Gu Fei's reason for slaying the man. Was he intending to kill everyone here? Suspecting Gu Fei, they kept their distance from him and took their weapons from their dimensional pockets to respond in kind if the need arose.
