Lea's expression was dead serious and caused Gu Mengmeng to recall his resolute killing spree last night and the vague impression hidden deep in her memory: under the raven moon and dark night, a man whose looks could not be seen clearly, held her with one hand while he used the other hand to... easily tear away Collin's arm and save her from the hands of the grim reaper.
She would not doubt Lea's words. In the Beast World where martial skills were the most important and where only the strongest could enjoy the fruits of their abilities. Lea had enough ability to fulfill every word he had just said and even if he really did it, nobody would feel that it was inappropriate - the winner was king and that was the correct principle.
