Lin Mu gazed at the being in front of him and knew that it was not natural in any way.

"There are even the traces of an invader in it?" Lin Mu sensed.

His instincts were telling him to end this being as soon as possible, and that was exactly what he was going to do.

~CLANG~

The humanoid mutant flexed his hands and the chains were stretched taught.

"GRAAAA!" The humanoid mutant shouted.

His cry was heard across the entire Iron bull city, shocking most of the commoners that were there. But those that were cultivators felt something more. They could sense the cultivation base of the being in its cry.

A few of them directly fainted while some of them coughed out blood.

Lin Mu's spirit sense captured everything and he knew that this was not good.

'Gu Yao has certainly reached a different level in manufacturing such beings…' Lin Mu thought to himself as he used blink and appeared at the back of the mutant humanoid.

Clasping both his fists, Lin Mu raised them high before bringing them down like a hammer.

~DENG~

~SPLAT~

The head of the humanoid mutant burst apart like a watermelon and its contents splashed over Lin Mu and his surroundings. Thankfully, there was the Mortal Strengthening scripture's armor which prevented the disgusting fluids from touching his clothes and skin.

~Clink~

The chains were rattled once more, as the body fell forward. Belongs © to .

~SPLASH~

Then with a splash it laid flat in the red and Grey fluid that was in the pool. A serious expression appeared on Lin Mu's face as he saw something even more shocking.

~HISS~

The red and Grey fluid started to move on its own and started to pour into the neck of the humanoid mutant. Under the surprised look of Lin Mu, the injury of the humanoid mutant which was life-ending, started to heal!

The flesh started to regrow and the bones started to mend. First, the veins extended before the bone rose from its spine. More flesh started to bud and grow from the base before the skull started to form as well.

Lin Mu continued to watch, feeling that this was important and saw the head being reformed in about five minutes.

"This… this is beyond normal…" Lin Mu muttered.

"Such vitality is truly abnormal for a being of this cultivation base… the things that compose this humanoid mutant are not normal. It seems like Gu Yao has used the impure Yin Qi and the invaders remnant to form this being…" Xukong said.

Once the head was fully formed, its eyes opened up and it looked at Lin Mu again. This time, though, it didn't have the slight hint of intelligence that it used to before. This time, it looked completely feral.

"GFRAAAAAAAAAAA!!!!!"

The humanoid mutant let out a head shaking roar and terrified the commoners even more. The shopkeeper who had seen it first, was now completely unconscious and was just some distance from his former property.

Lin Mu had felt the presence of something unusual in the city and had come here. His spirit sense could only tell that it was some kind of a human, but couldn't fully perceive it due to the strange energy muddling it.

But now that he had seen it, Lin Mu knew for sure that this was an experiment that was unknown by most.

"Tie Niu probably was never informed of this… why is this thing kept here, then?" Lin Mu couldn't help but question.

~CLANG~

The humanoid mutant pulled on the chains which restrained it again and this time they got weaker.

~KACHA~

The chains's finally snapped under the strength of the being and the runes surrounding them glowed.

~SHUA~

A formation array suddenly materialized as the spirit Qi in the area started to churn.

~WHOOSH~

A vortex formed above the large hole and spirit Qi started to pour downwards into the humanoid mutant.

"A spirit Qi gathering array?" Lin Mu recognized and was surprised.

~Shua~

Lin Mu disappeared in that moment and reappeared above the humanoid mutant's head. His legs were pulled up high, ready to kick the creature below. Spirit Qi gathered in his legs, amplifying his great strength even more.

Lin Mu then stopped controlling the weight of his body, and let it fall down while kicking as well.

~BOOM~

The sudden force generated from it was enough to compress the air and rip it apart, creating a sonic boom. The liquid below was directly blown away before the humanoid mutant was even touched.

Even then, the air pressure was enough to break part of its tough skin and create tears in it. Lin Mu's leg shone with a golden sheen that was masked by the brown armor of the mortal strengthening scripture.

The clash of the two skill colors made it look rather strange, but it did little to hide the true power that was contained within it.

~CRASH~

Finally, Lin Mu's heel touched the humanoid beast's head, shattering it into fragments of bone and flesh before continuing downwards to its neck. It didn't stop at all and shattered the collarbones, the spine and the ribs along with the sternum, all the while tearing all the organs in its body to mush.

~SPLATTER~

~BOOM~

Lin Mu's leg went all the way through the body of the humanoid mutant fully breaking it apart and finally struck the empty pool below. There it broke the stone floor and directly created an oblong crater that was five meters deep.

~SHUA~

The runes were also working at the same time, forming into a reinforcing formation. But even then, they could barely reduce the damage that was done to the hall.

~kacha~

And in the end, the formations broke apart from the force as well, letting the remaining power dissipate in the surrounding area.

The walls crumbled like they were made of chalk while the nearby houses and buildings developed cracks.

"AHH!!!"

"MY HOUSE!!! ITS BREAKING!!!"

Many commoners ran out for the fear of their lives, even though they had heard some terrifying cries outside.
