As all the leaders argue one with the others, King Bulda himself keeps silent and calm with a lazy expression like this has nothing to do with him. On the other hand, King Nexus listened to the argument between all the leaders with interest.
Since he is the one that gives out the most contribution in defeating Monster Overlord, he knows he will get the Monster Overlord corpse or perhaps the entire corpse itself. Now, he is looking at the greediest leader to trade some kind of benefit from them.
The Orces Kingdom is not only famous as a tourist spot because of its East Coast nation, but it is also one of the international trade hubs in Firuman. As its king, King Nexus prefers to trade the Monster Overlord rather than dealing with it.
Each Monster Overlord is different from the others. Some record even saying that the moment monsters reach grade six or become Monster Overlord they will mutate into different kinds of species.
