Time goes back a few minutes.

"Elsa, I will be gentler..."

"Mmm..."

- Afterward.

Suddenly, Green felt a vast energy surging from deep within his body. This energy instantly filled every cell in Green's body, making his exhausted body suddenly feel an endless supply of energy.

Green's body also became incredibly comfortable due to the sudden change, and the combination of these "two" pleasures brought him a blissful ecstasy akin to heaven on earth.

Suddenly, Green felt an uncontrollable force within his body about to burst out.

Intuition told Green that continuing like this might affect Elsa, so he decisively moved away from her. At the moment he left, a dark red energy column with a diameter of hundreds of meters shot up into the sky from his body's center, continuously increasing in size.

At the same time, deep within the vortex of energy, Green felt a tearing sensation throughout his body, but at the same time, an energy kept repairing and pulling his body back.

The two forces of destruction and repair within his body caused Green pain mixed with a hint of pleasure.

In the end, Green unexpectedly began to enjoy the feeling of his body being destroyed and repaired.

Although Green was not clear about what had happened, one thing was exceptionally clear to him: his superpower had stopped activating at this moment. In other words, he had returned to his normal state before acquiring the superpower.

Simultaneously, this was also the first time since Green gained his superpower that he had released himself from the state of having it.

It wasn't that Green intentionally wanted to release it, but the impact of the energy deep within his body forced him to deactivate the superpower. Moreover, Green discovered that the endless source energy surging out from his body was not causing it to burst but instead being absorbed and fused by the newly born energy, gradually transforming into an even more powerful force.

This change was manifested by the energy column surrounding Green becoming thicker and thicker. At the same time, Green heard the crisp sound of sparks crackling. Upon closer inspection, he discovered small arcs of red and black intertwining around his body, appearing at some unknown time.

At this moment, Green felt an unusual itchiness on both sides of his forehead, but this sensation came and went quickly. In the blink of an eye, the unbearable itchiness disappeared, replaced by two short black horns.

Upon discovering this fact, Green was suddenly shocked. Could it be that his body had already transformed into the lowest-level demon? But why would such a significant change occur?

No matter how you looked at it, this phenomenon in front of him had nothing to do with the word "low-level."

However, the changes in his body did not end there. Green gradually felt that something was not quite right in his mouth. After feeling around with his hand, he discovered that two teeth seemed to have become harder and sharper.

Not only that, the sensation of tearing and pulling within his body was gradually weakening, and Green found that he seemed to be able to control the energy leaking out of his body.

So Green began to try to retract the leaking energy. The dark red energy column also stopped spreading at this moment and began to shrink. However, just when Green thought he could control this power at will, he suddenly felt a strange sensation in his tailbone, causing him to let out a soft moan.

In an instant, the energy column lost control and began to spread at a much faster speed than before.

Realizing this, Green was greatly alarmed. Without time to consider the strangeness in his tailbone, he focused all his attention on trying to retrieve the uncontrollable energy back into his body.

To Green's surprise, retracting this power was much easier than before, and it instantly returned to his body.

Only then did Green breathe a sigh of relief, but for some reason, he felt that something was off. It wasn't until he reacted that he realized his demeanor had become unusually arrogant.

How should I put it? It felt as if from this moment on, he was the master of this world.

Just like looking at the world he had built through his efforts, Green couldn't help but reveal a slightly wicked smile.

Saro Uth looked at Green from a distance and felt that something was off. Although Green's face was much more sinister than before, there were still traces of familiarity. There was no doubt that it was Green.

However, how could Green, who was not from the demon realm, emit such an aura?

It was as if...

Suddenly, Saro Uth's vision blurred, and when he snapped back to reality, he found that Green had already moved in front of him.

Gothner, who was not far away, instinctively took a step back. He hadn't noticed how Green had moved, as if he had disappeared and reappeared out of thin air, completely different from their previous encounters.

"...Who are you?" Saro Uth asked.

"Me? I'm Green, the Demon King of this world—wait, why did I say that??" Green's first half of the sentence was said with an air of arrogance, especially the tone of his voice, giving off an inexplicable evil vibe, like a textbook villain.

But in the next moment, Green's face showed surprise, as if genuinely confused.

In fact, it was true. Green had intended to tease Gothner, but the words that came out of his mouth were completely spontaneous.

However, Saro Uth treated Green's abnormality with caution. Suddenly, he thought of something and his expression changed drastically.

"Could it be that you, Green, have become the new Demon King?!"

"Call me Lord Demon King! Wait, am I experiencing a split personality??" Green's demeanor remained the same as before, but he felt that something was different. When he said the first half of the sentence just now, even he himself felt it was natural, as if he had always been the Demon King.

And it was Green's actions that made Saro Uth even more convinced of his speculation.

"There's no mistake. Green has become the new Demon King under the rules of the demon realm, and his power surpasses all other Demon Kings!"

Saro Uth couldn't help but sweat profusely. Even standing in front of Green like this, he couldn't help but feel a sense of inferiority from the depths of his heart. It wasn't just Saro Uth, but Gothner beside him felt the same way.

"What the hell is going on? What happened??" Saro Uth exclaimed.

However, Green was completely unaware of Saro Uth's inner turmoil. But he did feel that he was different from before. For example, the two hard horns on his forehead, the two sharp teeth in his mouth, and...

"Huh? What the hell! Why do I have a tail?? Is this the symbol of my kingship? Wait, what??" Green felt like his mind was playing tricks on him, even suspecting that he was being controlled by Elsa. But upon careful consideration, he realized it wasn't that simple.

Facing the tail that suddenly grew from Green's body, Saro Uth revealed the cruel truth.

"No, that's a characteristic you obtained after transforming into a low-level succubus from Elsa..."

"..."

Green's mouth twitched. As a grown man, having a tail with a heart-shaped tip felt completely wrong, even embarrassing and shameful.

No, he couldn't let this thing stay!

But just as Green had this thought and actually considered removing it, the tail retracted into his tailbone on its own, leaving no trace as if it had never grown in the first place.

At the same time, Green suddenly felt lighter on his forehead. He realized that the two black horns were gone, and not only that, the two sharp teeth in his mouth had returned to their original state.

"Huh? What the hell? Did I revert back to my original form?..."

Green looked left and right, realizing that the parts that had just grown had all returned to their original state. With this bold idea in mind, Green's horns, teeth, and tail grew once again.

Like discovering a new toy, Green kept trying to retract his tail and found it increasingly amusing.

As for Saroth Uth and Gothner, they stood beside, staring at Green in astonishment. They found that whenever Green transformed into a demon appearance, they would feel a sense of submission from the bottom of their hearts. But when Green returned to his original form, that feeling instantly disappeared.

It was as if he could switch between the two states at will - and judging from his current performance, that seemed to be the case.

"Hey, this is kind of fun!" Because of his playful nature, Green mischievously reached out his hand towards his tail and gently pinched the heart-shaped tip. Suddenly, he felt an indescribable sensation, as if his whole body was electrified.

Realizing this, Green immediately retracted his tail and returned to his original form, like a startled little animal. It seemed that he couldn't let others touch this thing casually...

Seeing Green maintain his human form, Saroth Uth and Gothner both breathed a sigh of relief. After all, Green's demon form was too oppressive, making them feel suffocated.

Even Gothner had this strong feeling, as if he was a helpless ant that could be crushed at any moment in front of Green, rather than an opponent who could go fifty-fifty not long ago.

"By the way, Saroth Uth, do you know what's going on?" Green asked while checking his body for any abnormalities.

Thanks to Green maintaining his normal state, Saroth Uth could finally speak normally and relievedly explained his speculation without reservation.

After Saroth Uth's explanation, Green roughly understood the reason for his transformation.

"So, I became a demon king because of the rules of the demon world that give birth to demon kings?"

"That's right. Generally, demon kings appear by chance, but now it seems that if there is only one individual in the entire race, even if this individual is artificially created, they can become a demon king... The change you just experienced was probably the result of becoming a demon king."

"Uh, so according to this principle, can we create a demon king?"

Green was shocked. He had never thought that a demon king could be born in this way.

At the same time, Green thought of a possibility.

"Based on the current situation, is it possible that the possibility of creating a demon king is not known to the public?"

"No, I just came up with this speculation temporarily, and I can't completely confirm if this is the reason. But I think it's highly likely."

"I think your speculation is quite credible. If other demons were to know about this, it would probably... lead to a self-destructive war in the entire demon world, right?"

"..."

Saroth Uth didn't continue speaking, apparently realizing the danger of this situation.

At this moment, Green turned his head to look at Gothner and transformed into the demon king's form again.

In an instant, the overwhelming pressure inherent to the strongest demon king engulfed both of them, especially Gothner, who was targeted by Green. He felt unbearable suffering.

He had never imagined that things would develop in this direction. It was simply unimaginable.

At this moment, Green revealed a typical villainous smile and spoke in a dangerously tone:

"Gothner, you should also understand the consequences if other demons were to know about this. And I don't want to see my people killing each other. You are a smart person, you should understand what I mean, right?"

"I understand... I understand!" Gothner replied.

The next moment, Green returned to his original form, looking incredulous:

"I can't believe I said something like that. Could it be the influence of evolving into a demon king? It's as if this demon world has truly become my possession... By the way, where is my dear Elsa? Have we forgotten about her?"

Suddenly, Green transformed into the demon king's form again, looking panicked. Ignoring Saroth Uth and Gothner, he released his senses and immediately flew towards the direction where Elsa was.
