The highest area on the First Peak was not covered with many large trees. Instead, the area was covered by grass, and there was no building in that area. Xue Mingyu led Yu Ming and Wu Jingguo to the area after the three of them left the Demon King's manor.
Previously, Xue Mingyu asked Yu Ming whether the green-haired demon wanted to meet Bolin and the others or not, and Yu Ming, without thinking, immediately answered that he wanted to meet the demons who previously lived in the South Slum.
The reason why he dared to go to the First Peak after returning to the Xinyang Imperial Palace was because those weak demons were 'kidnapped' by two demons from the North Peak, and that was why he felt worried in his heart, afraid if those weak demons would be eaten alive by the heartless demons in the North Peak.
