Gustav's fist still slammed into the inmate's chest, but he also received the full brunt of the energy attack.

Bang! Bang!

Both of them were blasted backward, and cracking sounds rang out.

Gustav landed on his feet about seventy feet away from his initial position. He slid backward for a few seconds while the other inmate slammed onto the ground with his back and a broken sternum. He spat out blood and repeatedly coughed before passing out.

Gustav was back at his former position after taking that attack.

"You're bleeding!" The girl who Gustav saved earlier shouted out after noticing the palm-sized hole in Gustav's left shoulder area.

"I'm fine," Gustav voiced out as blood rolled down his arm.

'These ones are truly experienced, unlike the opponents I have been facing in the past,' Gustav said internally as he stared at his shoulder injury.

Even though that inmate was weaker, he still managed to injure Gustav.

Before the girl could speak another word, Gustav had already dashed forward to engage the remaining inmates.

The rest of the inmates, just like their companions, were also unable to properly follow Gustav's speed. This was a resultant effect of their bloodline abilities getting weakened before being thrown into Caskia ruins. However, due to their previous battle experiences, they were still able to put up a little bit of fight.

Gustav knowing that he had been careless earlier on and was getting too cocky due to his easy wins in the past, changed his viewpoint. He decided that he would handle future battles with caution from now on.

In a few, the remaining two inmates were taken down by Gustav while the group he saved just watched from the side.

They wanted to assist him when he was engaging the inmates previously, but not only were they awed by his movements, they also couldn't properly follow his speed, so they didn't know how to attack.

"You're still here?" Gustav questioned from upfront where he was standing in front of the last inmate he took down.

The group was brought out of their reverie and started thanking Gustav for his help.

Gustav just nodded and asked them to leave once again.

"Why don't you join our group? We'll let you be the leader," The girl with superhuman strength proposed.

"Hey Laura, leading is not only based on strength," The other guy fighting beside her was not in favor of the idea.

"If it is based on weakness, why weren't you able to defeat those inmates yourself?" Laura asked with a tone of ridicule.

The guy felt ashamed and was about to retort when Gustav replied, "Not interested,"

After saying that, Gustav went to grab the bodies of the inmates and stacked them together in a particular place.

"Why are you dragging them around like they are dead?" The other girl in the group who had a binocular on her right eye asked.

"Because I am going to kill them," Gustav replied while squatting.

The entire group was shocked by Gustav's calmness when he mentioned killing the inmates. He sounded like taking the life of others was just a casual thing to do.

Even though these were inmates, some of them still felt Gustav shouldn't kill them.

-"We should give them a chance,"

-"They are serving their term already,"

Two guys from the group voiced out together.

"I also don't think you should kill them," The girl with binocular said.

'A team of dorks... No wonder they say birds of the same feathers flock together,' Gustav said internally.

"They're serving their term but did staying in here change them? Have you forgotten what they were going to do to you?" Gustav asked the girl in binocular, who shivered slightly the moment Gustav poised that question.

"Also... If you think you can stop me from killing them, you're free to come and try," Gustav's fingers increased in length as his right hand transformed into that of the bloodwolf's.

The ones who didn't want him to kill the inmates could only watch as Gustav squatted and his claws dug into the neck of the leader of this group of inmates.

Blood trickled down the neck of the inmate as a system notification appeared in Gustav's line of sight.

[Requirement for Bloodline acquisition has been met]

[Analysing Host compatibility with 'Muscle Enlargement Bloodline' 0%/100%...]

[Analysis complete: 84%/100%]

[Host compatibility with 'Muscle Enlargement Bloodline is 89%]

[Does the host desire to acquire this bloodline? Yes/No]

'I won't leave any loopholes behind,' Gustav said internally before proceeding to say yes to the bloodline acquisition.

The main reason why Gustav wanted them dead was to make sure he didn't leave any room for suspicions after taking their bloodlines.

Even though he could acquire their bloodlines without killing them, it would be suspicious that they were moving around without using their abilities after he defeated them.

The group was unable to stand there and keep on watching as Gustav slit the throat of each inmate after acquiring their bloodline.

Those who were against it started puking the moment they saw Gustav brutally slit the throat of the first inmate.

The girl who Gustav saved first came over to thank him again before their team left the passageway.

After Gustav acquired the four bloodlines, he stood up and proceeded to walk forward.

'With these, I should be able to perform more experiments with recreation,' Gustav smiled like a maniac as he moved forward.

He had wanted to try out recreation since that time, but he was unable to do so because he didn't want to make use of the four he had earlier.

He didn't see anything special in these four bloodlines, so even if they lost their original properties after recreation, he wouldn't be bothered.

'I need to find more mixedblood inmates while I'm looking for the stones,' Gustav brought out his map and scanned through.

The Archinades didn't map out places where mixedblood inmates could be located. So, Gustav was trying to use the structure of the areas shown to depict places where these mixedbloods might be positioned.

Gustav remembered what the last inmate said while he was taking his bloodline.

"You're all gonna die... Even though we didn't get you lots, the silhouette wil... He has been freed..."

Gustav didn't care about all that and still killed him afterward since he didn't have the time to torture him to get answers.

However, Gustav still wondered, 'What did he mean? Silhouette...'
