The two beasts were hovering at the edge of the territory that belonged to the Slim Arm ape and also the Demon Spine ape.
Apparently, the father and son were now sharing territories as the Demon Spine ape had taken over the nearby territories that were left from the Sliver Beak Sky Soar eagle. Currently, the combined territories of the two Ape kings could be said to be as the second largest among all the beast kings.
The largest belonged to the Twin lights liger king of course while the third largest was that of the Olive Viper king. And in the last place was the Split Thorn horn beetle king. Though if one considered his case, the territory was not just restricted to the surface and extended quite deep.
A lot of the insect beasts lived underground and made their nests there. So if one considered just the surface area in which the beast kings and their subordinates lived, the Split Thorn horn beetle king's territory could be said to be the largest.
