Fang Bai knew that the reason why the Spiritual Medicines on "Blazing Flame Mountain," especially the Blazing Flame Scarlet Heart Fruit, were preserved so well and not extensively harvested by the Martial Artists of the Hidden Sect World, was very likely because of the group of Fire Wolves protecting them.
Wolves that live in groups usually have a Wolf King leading them. Fang Bai guessed that the strongest of the Fire Wolves must be the "Wolf King" of the pack.
To harvest the Spiritual Medicines of "Blazing Flame Mountain," one would have to drive away the Fire Wolves guarding the area, and the quickest way to do so would be to kill the Wolf King.
