He discovered the Humans on his first day. The evil and decadent creatures were forming groups to hunt the Underworld beasts. It was the first time he felt pity for the Underworld beasts.
The Surface World's decadent creatures were also fighting viciously against Eternal Kingdom's warriors.
Cherry was unable to understand why there were only small skirmishes instead of full-scale war. Of course, they killed each other in the skirmishes.
Why did Eternal Kingdom not exterminate the outpost created by the Surface World? If Eternal Kingdom was worried that they might not defeat them, why did Eternal Kingdom not inform Winterfell? This territory belonged to the Merchant Alliance, so Winterfell would definitely intervene if the Merchant Alliance came to know of the Human invasion.
Did Eternal Kingdom keep the Human output for some other special reason?
Cherry wasn't sure. He had to obtain more detailed intelligence to form a proper conclusion.
