@Gundam Any Xian Xia novel really. They all have tournament arcs eventually and since the fighters in Chinese novels are ALWAYS trying to kill each other (so the protagonist would look good when they thrash them instead) so having 1 or more than 1 (group battles) referee to standby and interfere with the fights is absolutely referee. And also, all these people are 'super' detectors - basically the more powerful a person, the better they are in every aspect and thus they can absolutely detect a weaker being's power level - so if someone is trying to kill someone else, they would know it in an instant.

@Diego He does. He is given full responsibility in overseeing the security of the Vytal Tournament by the end of Volume 2.
