The longer the battle went on, the more Green wanted to know how this gothner managed to grow so much. Not only was he incredibly strong, but he seemed to have endless stamina. His attacks didn't slow down over time, but instead became faster and faster, especially with his occasional outbursts of "howling resentment," which left Green dumbfounded.

"How the hell is this guy stronger than me?" Green exclaimed in frustration.

Facing gothner's relentless assault, Green experienced for the first time what it meant to be outmatched. And as if that wasn't enough, the damned underworld had a unique effect on Green. gothner's attack was like a storm, making it difficult for Green to respond. Furthermore, Green noticed that whenever he landed a near-fatal blow on gothner, he would fully recover within seconds. This terrifying resilience reminded Green of the Black Dragon King.

There was no doubt that the Demon King gothner was a genuine monster.

"It seems that if I don't kill you, this battle will never end," Green remarked, his face turning grim. He pushed gothner back with a sudden burst of strength, releasing all of his source energy. Seeing this, gothner burst into laughter.

"No one in the underworld can kill me, for I am the Demon King!" gothner's white hair floated in the windless air. His body was enveloped in a dark red light, and his eyes flickered with eerie red light, a symbol of his status as the Demon King.

Two tremendous forces simultaneously appeared in the underworld, causing the entire realm to tremble. Even Clitz, who was studying the Heart of the Universe, could sense these forces.

"I didn't expect gothner's power to be so terrifying! It seems my decision not to directly confront him was the right one. And that human who appeared out of nowhere... hmph, keep fighting. When both sides are weakened, I can reap the benefits. Hahaha!" Clitz laughed sinisterly.

Besides the Demon King's retinue, all the ordinary demonic creatures in the underworld were trembling under the pressure. Green's presence alone made them feel unbeatable, but gothner's aura as the Demon King completely crushed any hint of resistance they might have felt.

Saro Uth, witnessing the two preparing for a full-force attack, became increasingly worried. He didn't know gothner was so powerful, far stronger than he had imagined. However, he couldn't help but feel that Green wasn't in his best condition.

Compared to Green, Saro Uth was gothner's senior. Green's strength was so overwhelming that Saro Uth had abandoned any thoughts of fighting him, but gothner couldn't do the same. And yet, Green and gothner were evenly matched in their current fight, and Saro Uth felt that Green's power was much weaker than before.

The suppression from the underworld alone shouldn't have caused such a decline in his power. What had happened to make him lose so much strength? Was Green hiding his true power?

No, there was no need for him to hide his power in this situation!

Saro Uth's mind raced as he frantically searched for a way to turn the tide.

Just then, Green's full-force attack collided with gothner's, and a burst of blinding light erupted, dividing the world into two dimensions: black and white. But after mere seconds of stalemate, the white energy gained the upper hand, pushing back the black energy.

Saro Uth saw this and felt a glimmer of hope. And when the white energy broke through the black energy and struck gothner directly, Saro Uth breathed a sigh of relief.

At the same time, a deafening explosion sounded, shaking the entire underworld. Even Clitz felt the impact, struggling to maintain balance.

And the nearby Salo Uth and his group were hit by this huge shockwave and flew out.

Fortunately, the demons were unharmed and had already moved away from this area, so they did not die as a result.

Elsa, under the protection of Salo Uth, was not seriously injured.

And where Green and Gothner were originally standing, there was now a bottomless pit, but upon closer inspection, a stone pillar was seen standing in the depths of the pit, and Green was standing steadily at the top.

"Did we win...?"

Salo Uth muttered subconsciously, but at that moment, he suddenly saw a white gel-like substance fly out of the deep pit, and in a matter of seconds, it gradually turned into a humanoid shape.

However, compared to Salo Uth, who was observing the battle from outside the battlefield, Green was obviously more exhausted.

The attack just now was the strongest attack Green could make in this state, deliberately suppressing the attack range, aiming to concentrate all the pressure on one point.

In theory, such a powerful attack should have been enough to kill Gothner, but Green sensed Gothner's presence from the gelatinous substance floating in front of him.

"Are all creatures with fast recovery abilities this disgusting...?"

Green's knees suddenly went weak, and he half-knelt on the stone pillar, taking several deep breaths.

It had been a long time since he had experienced such a thrilling battle, but the current situation was not suitable for such a feeling, because the opponent in front of him could kill him.

"It seems I underestimated the suppression of the demon world on me, but... this guy is really a monster, to be able to survive after suffering that attack!"

"No..."

Gothner's voice suddenly entered Green's mind. Green focused his eyes and stared vigilantly at the gelatinous moving object in front of him.

Only to hear Gothner's slightly weak voice continue.

"In fact, I was killed by you just now, but the demon world gave me a second life because I am the Demon King, and this is the privilege of the Demon King in the demon world!"

"Damn, he can still resurrect??"

"Only the strongest Demon King of the demon world can have this privilege."

As the two briefly conversed, Green felt countless swear words rushing through his mind, and Gothner's body gradually returned to its original form, but without any covering.

And when Green saw that part of Gothner, his cheeks suddenly bulged, and he couldn't help but burst out laughing.

"Pfft...there's nothing there."

"..."

After hearing this, Gothner also curiously looked down, but soon raised his head calmly.

The two suddenly fell into silence.

Suddenly, Gothner's expression suddenly changed. He lowered his head again and looked at his crotch in horror.

"Gone...? How could this be..."

"Hahaha! Is this also a privilege of the strongest Demon King? Pfft!"

"Fuck!"

Gothner cursed, his emotions fluctuating greatly. Even Green could feel the despair in his heart and couldn't help but want to laugh, but soon Green couldn't find it funny.

Upon careful consideration, it was because Gothner became like this that he killed the other person.

And Green also noticed that Gothner's expression was colder than before, especially the strange red light in his eyes, gradually turning green, becoming even more eerie and creepy.

Green instantly felt a chill in his heart.

Green's superpower was to enhance his own strength by consuming the source energy within his body. At the same time, his body constantly generated a large amount of source energy like a perpetual motion machine. From the moment his superpower awakened, Green had maintained a state of constantly using his superpower, in order to avoid his body being unable to withstand the excessive source energy and exploding.

In other words, without the power brought by his superpower, Green was not much different from an ordinary young person.

But that's not the problem. If Green's source energy is at ten, then after using his superpower, the source energy will increase to one hundred or even one thousand. However, once Green depletes the one thousand source energy, it doesn't replenish over time. He needs to use another ten source energy from his own body to regain that one thousand source energy.

If this kind of superpower were to exist in someone else, that person would have to train hard to increase their strength under normal circumstances. But fortunately, Green has the ability to endlessly increase his source energy. So as long as he maintains his superpower, he can continuously increase his strength over time.

Because of this principle, once the source energy in Green is depleted, it's truly gone. Unless Green is given the same amount of time, in the short term, the enhanced strength may be enough to deal with ordinary opponents, but when facing a powerful being like Gothne, it would be a complete slaughter. Especially in the current state of being in the demon world.

Green had never experienced a more dangerous situation than now. Gothne also noticed this.

"I don't know what kind of human you are, but it seems like the power within you has disappeared. With your current state, you wouldn't be able to launch a second attack like the one just now, right?"

"..."

Green didn't answer directly, but took a deep breath and calmly stood up. Even though he was currently powerless, his mindset, which had been cultivated for a long time, wouldn't easily collapse. Instead, facing this desperate situation, Green had already simulated it countless times in his mind. And the final result was always the same— "I'll run!"

With a powerful push of his legs, Green leaped out from the center of the pit in an instant. After landing, he felt the vibrations from his joints and couldn't help but sigh.

"This feels just like when I used to jump around between tall buildings as a child."

Standing up, Green once again faced Gothne, but the latter had already moved from his original position and appeared behind Green without any hesitation, throwing a punch.

A sound, like a hard object hitting flesh, resounded as Green's body quickly flew out.

"You're too slow, even slower than my subordinates!"

Gothne looked at the thrown Green with disdain.

As Green's body fell onto the hard ground, a scorching heat replaced the pain, and at that moment, Green deeply realized the severity of the situation.

"It seems... I consumed too much source energy when I saved my parallel world."

Green had long noticed that a world like the Demon World shouldn't be able to restrict his body. The fact that his strength was being restricted in the Demon World meant that his power hadn't surpassed the limits of the Demon World.

But Green hadn't expected that such a powerful creature existed in the Demon World.

"I never expected to be defeated by my own arrogance..."

A mouthful of blood was coughed up from Green's mouth. It seemed that this was the first time he had suffered such severe injuries.

Green couldn't help but think that he would die here, but every time he recalled the faces of Aloof and the others in his mind, he regained the will to survive. Unfortunately, his body was completely unresponsive, and the rate at which his flesh healed couldn't quickly treat the injuries caused by Gothne.

At this moment, Green suddenly felt a "very powerful" aura approaching him.

Opening his eyes, Green saw that it wasn't Gothne who had arrived, but Demon King Saroth Uth.

"If I could free you from the restrictions of the Demon World, would you be able to withstand another attack of the same intensity as before?"

"Uh... theoretically, I should be able to..."

Green wasn't sure what Saroth Uth was planning, but he answered his question.

After getting the answer he wanted, Saro Uth smiled with satisfaction and then grabbed Green by the collar, throwing him forcefully towards Elsa, who was watching the battle from afar.

"Now it's up to you, Elsa."

Saro Uth muttered to himself, then put on a look of readiness to sacrifice everything, with a righteous demeanor, and walked briskly towards Gotne.

Upon seeing Saro Uth, there was a hint of confusion in Gotne's eyes.

"It wasn't you who spilled my food, so what does it have to do with you? Why are you coming over?"

"Smack!"

With a crisp sound, Gotne's face flew out along with his body, even rolling a few times on the ground.

Then, the voice of Saro Uth's provocation, with a gloomy face, followed.

"Now, is it related to me? Fat pig demon king - Gotne!"
