Since ancient times, peacemakers had needed both prestige and great strength.
Without superiority in strength as a form of support, mediation would not be successful even if the peacemaker was impartial towards both parties.
Based on the same rationale, if the mediator possessed superior strength, he would be able to decide the direction of the scene with a mere sentence and the other party would only listen even if the decision was biased.
They would have to swallow their grievances even if they were not willing to accept it.
After all, they could not afford to offend and disrespect the mediator. For example, many years ago, an intense extermination had occurred between two top sects.
During such a situation, one of the three hall masters of Hong Meng Sacred Hall, Left Hall Master, had stepped forward and immediately halted the all-out war between both parties with just one sentence.
