Forest ranger Lin Chao, who has traveled twice, is also protecting the forest today (in dire straits)
The ecological resources of this world have been severely damaged. There are only seven large mountain ranges left in the world. Each mountain range is guarded by such a number of people, but only the Ya'an Mountain Range is guarded by an 18-year-old half-elf.
Surrounding the resources in the mountains, human greed is not enough.
Purpose: ecological protection
