Jacob knew he had to now live with all those experiments Decker had done on him, and they can't be undone just like that, so he had no choice but to accept the reality.

He pressed the third button to see just what kind of information this would reveal,

"Blood Analysis Report:

"Because of four different tier bloodline fusions within human species 'Uncommon-Physique and Uncommon Bloodline,' this fusion is exceptionally harmful and deadly for the user.

"Please extract other bloodlines as soon as possible.

"(Note: Please Purchase a higher grade devise for more accurate blood analysis results and more information!)

"The heck?! Is this company selling products or advertising them by selling them?" Jacob cursed and berated the company behind this device harshly.

But he couldn't help but feel worried when he saw the Bloodline Analysis Report. Even without this device, he knew this kind of blood change couldn't be done as Decker did, and his being alive was a miracle on its own.

Jacob knew he was fucked and hated Decker even more, when he glanced at the glass cell filled with a blue liquid with a hint of Decker's blood.

"Sigh… let's see what the last button can tell me." Jacob helplessly shook his head like an old man.

A new display emerged,

"Blood Lifespan:

"User has approximately less than 2000 Days of life because of user blood fusion.

"(Warning: This result is not entirely accurate and only depends on the blood analysis.)

"(Note: Please purchase a higher grade device for more accurate blood lifespan results and more accurate information!)

"What, less than 2000 days!?" Jacob's eyes dilated when he saw this line and panicked.

There wasn't anything scarier than death for him out there, and definitely not after he was reincarnated and finally became free!

"No, this shity device is clearly flawed since they put such advertisements in every fucking report!" Jacob muttered to himself. He just didn't want to believe it, even though deep down he knew Decker's experiments were enough to gain such results.

Jacob threw the Blood Analysis Device on the table and just remained motionless on his chair while his eyes closed.

'What a stroke of damn bald luck, heh. I got this new life in this new mysterious world. But I already knew I'd die in less than seven years just because of a freaking little monster. Hah, truly lamentable,' Jacob thought while bemoaning his bad luck.

After he calmed down, he quickly accepted the fact about his lifespan because he wasn't someone who lived in delusions.

'Well, since this device had said to extract the types of the blood of other species can undo all this, then it might be possible to salivate my situation. Or I can always find another human and change his blood with my own. It's not like I didn't experience it already!'

Jacob's amber eyes snapped open as a vicious glint flashed past them before he regained his calm demeanor.

'thum… thum…'

Suddenly, a light sound of something knocking against a hard surface drew Jacob's attention, and when he looked at the source, he pulled an extremely frosty smile, 'He's awake. These strange liquids really do wonders!'

Decker was currently wiggling his limbs inside the glass cell while his mouth was opening and closing. He clearly was still shocked by what had happened to him.

Although Decker was completely fine, his two eyes were now just black sockets. Before, Jacob didn't hold back with his surprise attack and ruthlessly destroyed Decker's eyes.

Eyes were the weakest spot of any living being, and Jacob didn't know Decker was just bark and no bite. That's why he went for his eyes and was so ruthless with his attacks. Nonetheless, he didn't regret even a little what he did!

Jacob finally stood up and coolly moved toward Decker's cell with a wintry smile on his face. "Look what we have here, a blind little shit, huh? Say still and close your mouth!"

Decker suddenly trembled when he heard this deep voice filled with mockery and viciousness. All his movement suddenly stopped after this heavy voice faded.

'The Parasite Gem!' Decker instantly knew he had been enslaved, and his heartbeat shot up tremendously!

He finally remembered how he ended up like this, and an extremely weak figure flashed past his mind, 'How did that human manage to extract the Parasite Gem without dying?!'

His head was filled with these questions, but alas, he couldn't speak right now since he was now on Jacob's mercy, just like when Jacob was. Their positions have been swapped and changed!

Jacob was quite pleased with Decker's reaction, as he also pushed the bronze button on the button panel on the wall, just like Decker.

"Pig Head, come out!" Jacob also commanded Pig Head.

He won't be taking any risk with Decker since he knows nothing about what Decker is or what kind of things he is capable of, and Pig Head is his strongest trump card.

Because he didn't have free will, like Jacob and Decker, he was sure of it because Pig Head's eyes were always listless, with no luster of life whatsoever, which means he was dead or something like a death state. Or someone like Decker can never control such a monster!

Pig Head's eyes snapped open as he pressed something inside his glass cell, and the liquid started to sink.

'So, his glass cell had an inner control panel, which means Decker wasn't afraid he would turn against him. Moreover, he can easily awake from his sleeping slate. Was it the liquid or something else?' Jacob mused.

Jacob didn't dwell on this topic for now since Decker's cell was finally emptied, and he was eager to give Decker a taste of his own medicine!

He opened Decker's cell and calmly sat on the chair again while looking at expressionless blind Decker, who was standing there like a little puppet.

Pig Head also came out of his cell at this moment.

Jacob's lips curled as he said coldly, "I don't like the way you're standing, Slave. So… KNEEL!"
