The Thousand Ren Mountains stretched for tens of thousands of miles.
There was more than one towering peak among them.
They seemed to stand scattered everywhere, yet there was a faint pattern hidden within.
The lower the mountain, the lower the grade of mineral deposits within it, and the greater the number of low-tier exotic beasts lying dormant there. They won through sheer numbers.
The taller the mountain, however, the higher the grade of the mineral deposits it contained!
Not only that, but the tier of the mountain-guarding exotic beasts within was also higher, matching almost perfectly.
