While the Slim arm ape king was a little tempted by the offer, he didn't know if it would be good for his kin. For all he knew, it would just end up destroying them intend. And thus he thought of doing it later.

Lin Wu could see the confusion in the slim arms ape king's eyes and could guess what he was thinking.

"I guess you would like to see the proof for that don't you?" Lin Wu asked.

"Hmm… yes. Unless I see it with my own two eyes, I won't believe that your mutations will be beneficial to my kin." The slim arm ape king replied.

"No problem there. You can simply bring me one of your kin and I'll demonstrate. Though they need to be strong enough to bear the mutations, at least at the core condensation realm.

I haven't tried it on the beasts who are below it and thus don't know if it will work. Still, we can try out that option right now if you are willing." Lin Wu said.

The slim arm ape king thought over it and then nodded his head.

"Very well, if it is as you say then we can progress further." The slim arm ape said before letting out a cry the spread in the area.

~kikiki~

The sounds of monkeys and apes could be heard coming from everywhere and soon an army of them was gathered around them. The slim arm ape looked at the beasts and spoke to them.

"Bring me one core condensation realm and one Qi refining realm monkey from the jails." The slim arm ape ordered.

He had spoken in the human tongue again, but the monkeys were able to understand him. Lin Wu heard his words and was rather surprised.

'He's really trying to follow the way of humans huh…' Lin Wu thought.

Soon two monkeys were brought to the front and they had a lot of scars on their bodies. They had fierce looks in their eyes and were ready to fight at any moment.

"These are the criminal of my kind. You can test your mutations on them." The slim arm ape king said.

"Hmm… using criminal for testing… how 'human' of you…" Lin Wu said before looking at the two monkeys.

At first, the two monkeys had not seen the nascent soul realm beasts and thus were showing their fierce expressions. But when they finally looked up, they could see the four nascent soul realm beasts, two of which were none other than the leaders of the tribe.

Their faces fell and they couldn't help but feel terrified. Especially when Lin Wu's crimson red eyes stared at them. They felt as if they would be killed any moment and they shivered in their places.

"Who should we start with… let's see." Lin Wu muttered before making his choice. "You, come forward." Lin Wu ordered.

The one he had picked was the monkey that was at the first stage of the core condensation realm. Lin Mu reckoned that to make a better impression it was to use the tested method, rather than something new.

That was why he picked the core condensation realm monkey, as he knew they had a higher chance at survival. The beast in question wanted to resist, but the gazes of the two ape kings were terrifying and froze them in his place.

"Ah, you're not going to move, are you? Let me get to you instead then…" Lin Wu said, but before he could do anything else the monkey flew towards him.

Or rather he was sent flying towards him. The other core condensation realm monkeys that were beside the monkey kicked him ahead, not wanting to piss off whatever beast that was in front of them. They could all feel the power from him and knew better than to test anything.

Who knew if he would end up picking them instead of the monkey that was chosen before. Even with their leader here, they couldn't help but feel scared for some reason. It was as if there was a hidden pressure that exuded from Lin Wu that was incomprehensible to them.

"Oh, this works too…" Lin Wu said before extending his tail towards the monkey.

The monkey shivered in his place, while the others watched with apprehension. They didn't know what was going to happen and thus they were keeping silent. Seeing that their king was also doing the same, they didn't even dare to breathe.

Lin Wu's tail extended a small spike that touched the monkey's forehead and the process.

'System, take over. Try to see if you can replicate the mutations faster than before that.' Lin Wu ordered in his mind.

The system had already analyzed the mutation that had occurred in his servants and could now replicate the process. It had informed Lin Wu that due to their connections, the bloodlines would resonate and this would induce a mutation.

This also opened up a lot of opportunities for Lin Wu as well. One of the theories that he had was, the more his cultivation base increases, the more strong the mutations will get. There was even a chance that those that had already mutated before may experience it again.

Though one question had stumped him. He didn't know if this could be repeated endlessly as long as he had spirit Qi or if he had a limit that he did not know of currently. Even the system was unable to give an explanation to him and he could only figure it out along the way.

Both the ape kings as well as the beetle king were using their spirit sense to observe the monkey, though they did not dare to directly probe its body as they didn't know if this would affect the process or not.

All of them had either seen or heard of mutant beasts and the mutations and thus knew better than to interfere in such a risky process. Just like this, a minute passed before Lin Wu removed his tail from the monkey's forehead.
