Lin Wu's quick agreement was not something that the Slim Arm Ape king had thought of. Even if he knew that Lin Wu could do it was going to do it on his own, he was sure that Lin Wu would probably ask for something extra, perhaps.
He didn't know what Lin Wu would ask, but in his mind, the common option was none other than his kin, the Black Fur Monkeys. Even though they were not of the same species directly, being of the same source, the Slim Arm ape king still considered them to be his kin.
Back then, Lin Wu had asked for some of his kin to join him. Of them all, about ten of them had decided to join Lin Wu. And those that joined were now many times stronger than before.
In fact, two of them were already at the Nascent Soul realm. Even though they weren't as strong as him, they were still far stronger than any other beast in the forest. The Slim Arm ape had met them before and knew that they had gone on an entirely different path than what he had seen.
