I'm seeing a lot of comments over 3 points here.
1. "How is he that powerful to stop the goblin emperor." The answer is that his actual power level is above 200k, why would he struggle over a 6k goblin?
2. "Raising the bid is so stupid." There are a couple of things to keep in mind here. For starters, it's an auction, so the 5k is just an estimate. If the other guy offers 1 more coin than he does, he lost her. 30k is just his way of making sure he can buy her and an amount he doesn't mind losing + thinks he can get in that time. Keep in mind that his opponent is essentially a rich businessman, so it's likely that the bid will surpass 30k.
3. "What are these proportions, holy shit." You got a point there.
