Lin Wu's body was hovering about a meter above the ground and he was now trying to move around. He followed the same method and slightly tilted the repulsive force to a diagonal angle.

~Crash~

As soon as he did that, his body uncontrollably shot towards a rock and smashed it to pieces.

"Uff… need more practice." Lin Wu said to himself.

And just like this, Lin Wu continued practicing for a while.

But while he was doing this, his servants were undergoing something else.

The mole beast was sprawled on the ground and writhing in pain.

"ARGH! What is this pain!" He cried.

There was a piercing headache in his head arising from the rhombus gem. It spread from there all the way to his core, making him tremble and shiver. This had started the moment Lin Wu broke through the Nascent Soul realm.

The other three servants of Lin Wu, the beetle beast, the sparrow beast, and the swan beast were in a similar condition.

The beetle beast was currently surrounded by a lot of other insect beasts, and they were all looking at her with concern.

"What is happening to junior sister? Why is she in pain?" One of the insect beasts questioned.

"I don't know one moment she was fine but then suddenly she was like this." Another insect beast said.

"Move aside!" A voice suddenly said from the back.

As soon as the insect beasts heard the voice, they knew who it was.

"Ancestor!" They recognized.

The beasts moved aside and let the large beetle king approach the beetle servant. She was still crying in pain and couldn't move much. The Split thorn horn beetle king placed his long horn over her body and closed his eyes.

A minute later he opened his eyes, which were now filled with shock.

"It can't be… how?" The beetle king muttered.

"What's wrong, my king?" one of the close aides of the beetle king questioned.

"Yes, what happed to junior sister?" Another insect beast asked.

"Her bloodline… it is mutating." The beetle king said.

"Mutating? Is it even possible?" A stick insect asked.

"But isn't she one of your descendants, my king? Did she perhaps have a parent that was different?" The aide of the beetle king questioned.

"I do not know. There are far too many descendants that I have. Since she was able to reach the Core condensation realm, she was eligible to follow under me. But now… I do not know." The beetle king answered.

"My king… could it be… due to the Heavenly tribulation that just occurred?" The aide asked.

The beetle king's eyes went wide, and he connected the dots.

~Crack~

And just as he did, a change occurred in the beetle servant beast. Her horn started cracking and the hard layer that was on it fell to the ground. The insect beasts watched in horror and thought that she was going to die.

But then suddenly a crystallizing growth appeared on the horn. It started at the base of the horn and went all the way to its tip. The crystalline part was was emerald green and shone with a pale light.

"This…" The beetle king recognized the faint aura that was now coming from his descendant.

***

A similar change occurred in the other three servant beasts of Lin Wu.

The mole beast's claws and teeth fell out and in their place emerald green crystal claws and teeth grew.

For the sparrow beast, its feathers fell out and new ones grew. These feathers had a green sheen and looked sharp if one looked from the side.

The swan beast had the most radical change, though. The rhombus gem in its forehead started growing and formed a helmet like layer over its head. The smalls feathers on its head all fell out and were now covered in a hard emerald green crystal.

Its beak grew a bit longer and also changed to become crystalline. Its legs grew crystalline scales and its talons became crystalline as well.

After these changes presented in the beasts, they all fell into a deep sleep. But if one looked at the spirit Qi around them, they would find that it was being absorbed by their bodies and their cultivation base was increasing slowly.

In a few hours, all of the servant beasts reached the mid stage of the core condensation realm.

Lin Wu was completely unaware of it and was on his nth attempt at flying when he got the notification from the system.

~Ding~

~Crash~

Lin Wu lost focus upon seeing the notification and crashed to the ground again.

"Huh? What the hell! How did all of them break through at the same time? And what's up with the mutations?" Lin Wu wondered.

Lin Wu opened the servant data and checked how they were now. He was surprised to see their appearances as all of them now had the same emerald green crystals like he had incorporated into their bodies in some or the other ways.

"Was this… caused by my breakthrough, system?" Lin Wu asked.

~Ding~

——

ANSWER: The gems that the host emended in the bodies of the servant beasts responded to the bloodline resonance that happened when the host broke through the Nascent Soul realm due to the connecting links between them and the host.

This affected their beast cores and oppressed their own bloodlines. This further resulted in their bloodlines forcefully adapting to the bloodline suppression by mutating.

The mutation led to an increase in their quality of bloodlines and thus triggered break thorough of their own causing them to directly reach the Mid stage of the Core condensation realm.

"Huh, so their aptitudes increased because of me too now. Well, I guess it's just good for me then, I can use them for even more tasks." Lin Wu stated.
