First off, we kind of expected that. No way was author just going to give MC some OP ass powerful monster just like that. And all we got from that was the fact that there are 4 other humans who have the power of rulers as well. Does that mean they're like MC? Do they too have the ability to keep leveling? If so, they're much better at keeping quiet about everything than MC did and they're most likely evil because if they do hold immense power, they don't seem to be helping out with all the dire needs going on around the world since there's absolutely not a single piece of news on them.
And regarding Hwang Dong Soo, that coward ass bitch, I can't wait to see him get absolutely fucking stomped. I hope he dies this time. I was wondering when he was going to pop up in the story, and this is how he shows up. What an absolute coward. I hope MC shadow extracts this piece of shit instead. Would be funny if he uses him as just a manservant after soul extraction instead of actual combat.
