Vital Essence?

The Slim Arm Ape was the last beast Lin Wu had considered being close to this. 

'If he really is able to make one of his subordinates or descendants into the fifth ruler, the balance of power would probably shift again. It's likely that the Split thorn horn beetle king would become the one with the least power, falling from the third position to the fifth directly.' Lin Wu analyzed.

"Which one of the Slim Arm Ape king's subordinated is close to reaching the Nascent Soul realm?" Lin Wu questioned.

"It's not just any subordinate but rather the son of the Slim Arm Ape King himself. Unlike the ape king, his son is more talented and apparently is a hybrid beast having two bloodlines." The Mole beast answered.

"Two bloodlines? Which one is the second one?" Lin Wu questioned.

Except for himself, Lin Wu had not seen any other beast that had two bloodlines in them, thus Lin Wu was intrigued by it.
