Supreme Harem God System

Chapter 1577  Bloodline Upgrade.

"AAAAAGGGGGHHHHHHHHH!!!"

Veins popped out all over Nux's body and his entire body started trembling, unable to hold on, Nux used his last trump card, He let go of the beast he had been holding back all this while, and once again, the Black Hole was set free. *BOOOM* What felt like an explosion happened inside Nux's body. Two different factions were fighting for supremacy, one faction was visibly stronger than the other, the results of the battle couldn't be any clearer, but then, a third faction joined in. A faction much different than the other two factions, in an instant, the winning faction's control over the battlefield diminished as the new Faction took over. The two previous factions were completely helpless. This is exactly what happened in this case. Once the Black Hole was allowed to act, it started devouring Felberta's blood and as if it knew exactly what it was supposed to do, it started weakening Felberta's blood to the point it became weaker than Nux's. With that, it didn't take long for Nux's blood to absorb Felberta's weakened Blood and adapt further, adding all her abilities into it and getting stronger at the same time. And this wasn't the end. Once the Black Hole realized that Nux's Blood was now strong enough, it slowly started releasing more of Felberta's blood, making Nux's Blood devour more of her blood and get even stronger. Yes, the Black Hole was using Felberta's blood as a nutrition to strengthen Nux's blood. It started with a small amount, and slowly, it continued to raise the concentration of Felberta's blood. 1%...

2%...

3%...

10%...

25%...

Slowly and steadily, Nux's Blood continued to devour more and more of Felberta's blood and got stronger. If before, Nux's Bloodline's Level was a little stronger than 1% of a Low-Level World's Progenitor (the bloodline that he got from Caesar and mutated because of the rest of the Bloodlines he had), now his Bloodline level was constantly increasing as it was slowly becoming as strong as the 49% of a Middle-Level World's Progenitor (the Bloodline he got from Felberta). Yes, it was a direct jump from 1% Low Level to 49% Middle Level and no, the jump wasn't just related to Eldraeth Blood Nux received. Bloodlines didn't work like that. To understand what happened clearly, understanding how the Bloodlines work was essential. Taking Yrniel for example, the Bloodlines here were divided into nine levels. Low, Medium, High, Exceptional, King, Emperor, Saint, Primordial, and finally, the purest and strongest Bloodline, the Progenitor's Blood. In other words, the names and the number of levels might be different, but the general level of the Bloodline was the same. It was similar to how Divine Stage Cultivators were called Ultimate Level Powerhouses in the Lowest Level World Nux and others visited. Another example of the same would be Vulpiana, the Foxkin. Since the Foxkins were from another world, their Cultivation Stages and bloodline levels were different. Their cultivation level was determined by the number of tails they had while their bloodline levels were divided into eight levels. Mundane Blood Minor Blood Major Blood Elemental Blood Illusionary Blood Time-Space Blood

Celestial Blood And the Progenitor's Blood. These levels might be different, but if compared, these can be somewhat connected to Yrniel's Bloodline Levels where Celestial Blood would be equal to Primordial Blood, Time-Space Blood would be Saint Level Blood and so on. Just like these two worlds, other worlds, no matter the tier they belonged to, were all the same and different beings of these worlds had different levels of bloodlines. What differentiated one world from another was the energy a particular world had. The Low-Level Worlds, for example, had less energy, so a Bloodline that belonged to that world was weaker compared to high-level worlds. Because of this difference, despite there being similar levels of Bloodlines in different worlds, their strength was different. A Progenitor's Blood from a Low-Level World might be weaker than a Medium or a High-Level Bloodline in a High-Level World, that was how large the disparity was. A disparity that not many could overcome. And Nux…

He had done it unknowingly. When the tier of his Bloodline rose from Low-Level World to Middle-Level World because of Felberta, it wasn't just the Eldraeth Blood that was being affected, his other Bloodlines were being affected as well. Now… Nux was no longer a Primordial Level Dragon, Primordial Level Vampire, Primordial Level Incubus, King Level Shadow Demon, Saint Level Catkin, and Saint Level Elf of a Low-Level World, All his Bloodlines, because of his Eldraeth Progenitor, were now connected to a Middle-Level World and had evolved to Middle-Level World's Bloodlines. It was a straight jump in a tier of his Bloodline. Yes, a whole new world was unlocked, Nux didn't know if there were new abilities that came with these upgrades or not, however, one thing was sure, He had become even stronger than before, much, much much stronger. And all of this happened because the Black Hole helped him absorb all of Felberta's Blood without leaving anything behind. "Haaah… Haahh… Haahh…"

The process lasted for 2 whole years, even with the help of Black Hole, Felberta's Blood was simply too strong for Nux's Blood to absorb it in one go, even when the Black Hole continuously weakened Felberta's Blood while Nux's Blood got stronger and stronger, the process took much more time than anyone expected. And all this while, the pain Nux felt as two Bloodlines fought for supremacy inside his body was… Something he didn't want to remember. After all, he pretty much rebuilt his existence and upgraded himself from a being of a Low-Level World to a Medium Level World. Of course, he and even Felberta were still connected to Yrniel, a Low-Level World, they just had a Medium Level World's Bloodline flowing in their veins. "Haaah… Haahh…" He was breathing hard while his knees were on the ground, beside him was Felberta whose face was covered in tears. The rest of his wives were all here as well and were looking at him with worried looks on their faces. Even Vyriana, who had tortured Nux to the point that he was pretty much numb to all the pain was nervous. After all, even when she was training him back then, never once had she seen Nux constantly scream in agony for years, yes, he felt pain, however, as time passed, his body adapted to it to the point he became numb and only a pain stronger than his pain tolerance could hurt him and even then, his adaptation kicks in and sooner or later, his pain tolerance increases and he overcomes the pain. After thousands of years of repeating the process over and over again, Nux's pain tolerance was absurdly high, heck, he has even experienced death countless times in the illusion, honestly, even in the entire universe, not many beings with similar pain tolerance to Nux exist, So the fact that someone like Nux was constantly screaming in pain as everything happened told the women all they needed to know. They couldn't even imagine how horrifying the pain was. "Nux…" Felberta called out in a low voice. Seeing Nux in this state tore her heart into pieces, just now, the two of them were enjoying the happiest moment of their life and now, her husband had been experiencing hellish pain constantly for 2 whole years. And all of this was her fault. If only she hadn't been greedy. If only she had given normal Blood to Nux instead of giving 49% of her total Blood Essence. She, out of all the people, should have known just how different her blood was compared to other beings in Yrniel. Faustina had warned her about this before, she had told her that she was different, but in front of Nux, she forgot it all and got greedy, and because of tha-

"…?" Felberta tilted her head as Nux raised his head, glanced at her and started gently caressing her cheek with a loving smile on his face. He gently wiped her tears, cleaning her face that was wet from tears and looked like a mess because of the marks left by her dried tears. "Thank you, Fel." Nux spoke, his voice heavier than usual. "…?" Felberta was still confused. She still didn't know what sort of gift had she given to her husband. Honestly, Nux didn't know anything either. He knew he had gotten stronger, but by how much, he had no clue, for now, he only said these words to calm Felberta down and to make sure that she didn't blame herself because of this. However, as his first wife, Felberta knew him more than he himself did, his tactics, Felberta was aware of them all and hearing him saying those words, she couldn't hold herself back and started crying out loud. "I am sorry, I am sorry, I am sorry, I am sorry." Felberta cried. With her head on Nux's shoulder, she cried her heart out, the more she thought about all this, the guiltier she felt and seeing this sight, Nux's heart tightened. All the pain he experienced before, he was ready to experience a much worse version of that pain for eternity, but this…

This wasn't something he had the heart to see. Seeing his Fel cry… It made him weak. Unable to control himself, he grabbed Felberta's body and brought her into his embrace. *Crack* Because of his newfound strength, a simple hug from him cracked Felberta's bone, which shouldn't be possible since Felberta was a Complete Divine Stage Cultivator, someone who, in theory, was much stronger than Nux. Right now, however, neither Nux nor Felberta cared about this. Felberta simply wanted to be in Nux's embrace so she ignored the pain and snuggled even closer to him, Nux on the other hand was worried and quickly used [Heal] to treat her. The ability worked, in an instant, Felberta's cracked bone became as good as new, and this time, Nux finally noticed something. His ability…

He was able to use it much faster than before…

Not just that, but his increased strength that was even able to break a Divine Stage Cultivator's bone when he didn't even intend to… Something was not right.

With his free hand, Nux clenched his fists and in an instant, he recognized this feeling. His body was overflowing with strength. With just one glance, he understood how much he had improved. 'But how is this possible…?' Nux was confused. He still didn't know how Bloodlines and World Tiers worked and with the limited knowledge he had, linking everything and understanding what happened was difficult. He just knew that he had gotten stronger. And his Fel was the reason why this happened. "Thank you, Fel, really." He spoke, his tone even gentler than before. "And stop crying, it was nothing.

Think of it as a form of training and I can assure you, The results from this training were damn good." Nux spoke. His words, combined with being in his embrace calmed Felberta down. Her increased heartbeat started returning to normal. Sensing that, Nux calmed down as well. He then turned towards the rest of his wives and smiled at them. He knew they were worried and the only reason they didn't surround him the moment he regained his mind was because they knew Felberta's condition and wanted her to be alone with Nux for a while. Of course, Nux couldn't be more grateful because of this. He loved how despite trying to compete and one-up each other every single time, when it really mattered, his wives always stood together, even if it was just for his sake. Nux was indeed a lucky bastard. And he knew that well. His smile widened, his eyes shined as he glanced at his wives, clearly, his intentions were anything but pure. His wives smiled back. Their intentions weren't pure either. In an instant, the tense atmosphere disappeared and something entirely new started. However, During all this, Nux ignored one essential thing. The leash he usually puts on the Black Hole… He didn't put it back on, The Beast was still free. And after Felberta's Blood, It was now locked on a new target. *BOOOM* Once again, the beast moved, and this time, what was going to happen, would shock not only Nux and his wives but the entire Universe.
