Unless there is a guide familiar with the Ten Thousand Mountains, or a map of the Ten Thousand Mountains.
Lu Yu doesn't have a map, but he does have a guide.
Although White Young Master lives in Greenhill Peak, he is quite familiar with the Ten Thousand Mountains, which isn't far away.
Moreover, as a member of the demon clan in the Core Formation Realm, he is considered a high-level demon, and has the opportunity to participate in gatherings of the demon clan within the Ten Thousand Mountains.
As time passed, White Young Master got to know quite a few demons in the Ten Thousand Mountains and learned various information about it.
Among these, the Golden Eagle King, who reigns over a region in the outskirts of the Ten Thousand Mountains, is also quite renowned among demons in the Core Formation Realm.
Thus, White Young Master is also familiar with the Golden Eagle King, although he hasn't had much interaction with him.
