Mu Ye had a profound understanding of all sorts of soul beasts, as well as heaven and earth treasure-type food. The blood that he spilled over Tang Wulin was that of a Deep Sea Devil Whale. The Devilsoul Great White Shark and the Deep Sea Devil Whale were natural enemies, as both were the overlords of the sea.
Comparing the two, the Deep Sea Devil Whales were stronger but were far less numerous than the Devilsoul Great White Sharks. The whale's blood had a special characteristic in that it was highly adhesive. Moreover, once it came into contact with a strong blood essence's fluctuation, it produced an even stronger smell.
How could the Devilsoul Great White Shark not recognize its enemy's smell? Naturally, it launched an incessant pursuit.
