After Saloius's explanation, Elsa finally understood the changes that had occurred in Green.

And upon hearing that Green had evolved into a demon king, Elsa's face was filled with disbelief.

"Did I... create a demon king?"

"You could say that."

Saro Uth nodded affirmatively.

Elsa could never have imagined that things would develop to this extent. Originally, she had only wanted to help Green break free from the constraints of the demon realm and defeat Gothner to save his life. She hadn't even had much hope for success. However, Green had directly evolved into a demon king, and it seemed that his power far surpassed Saro Uth and Gothner.

This unheard-of turn of events was completely unexpected.

Green was not an ungrateful person. Elsa's actions not only brought him back from the brink of death, but also gave him a new lease on life.

Therefore, Green intended to hand over the management of the demon realm to Elsa - although it felt somewhat self-aggrandizing, the fact was that Green was now fully qualified to be called the king of the demon realm.

If there was anyone who had any objections, it would probably only be the pile of bones that made up the skeleton.

Green also sought advice from Gothner and Saro Uth on this matter, and both of them made it clear that Green could do whatever he wanted. In fact, for Saro Uth, there would be no harm in Elsa gaining the power to manage the demon realm.

As for Clitz, both of them held the same opinion.

"If Clitz wants to resist, then we can only eliminate it."

"Wipe it out."

Gothner made a throat-slitting gesture, exuding a murderous aura.

In reality, Gothner had no interest in what Clitz wanted to do, but since he had made such a promise not long ago, he no longer had any other emotions towards Green's ideas besides support.

Anyone who dared to defy them could be wiped out.

"In that case, we need to find him quickly. Otherwise, he might use the Heart of the Universe before it's too late, and I still want to study that thing."

"Heart of the Universe? Is Green interested in the Heart of the Universe too?"

"Well, I am somewhat interested."

Upon hearing Green's words, Gothner's eyes lit up, but then he looked regretful.

"If only I had sent my subordinates to seize the Heart of the Universe earlier. Although I have no use for it, if it could help Green, that would be great. What a pity!"

Seeing Gothner's reaction, Green had a feeling that he might know something, so he asked:

"Do you know anything about the Heart of the Universe? Tell me in detail."

"Understood!"

Afterwards, Gothner revealed all the information he knew about the Heart of the Universe.

According to Gothner, the Heart of the Universe was the purest energy in this universe, far surpassing the energy within humans and demons. Comparing the two was like comparing an ocean to a drop of water.

The appearance of the Heart of the Universe was like an egg, and in fact, it was indeed an "egg".

It was formed by a stone with a much lower purity than the Heart of the Universe but with the same properties. The location and method of the stone's formation that gave birth to the Heart of the Universe were completely random. To give birth to the Heart of the Universe, both quantity and time were indispensable.

At this point, Green couldn't help but think of the place where he had discovered the Heart of the Universe.

There were a large number of Largragon stones there. Combining Gothner's explanation, perhaps a large quantity of Largragon stones, along with the passage of time, was the key to the birth of the Heart of the Universe.

"Speaking of which, I heard some rumors that you, Gothner, obtained a Heart of the Universe a long time ago, didn't you?" Saro Uth suddenly interrupted.

Gothner did not shy away from this and admitted without hesitation what Saro Uth said.

"I did absorb the energy of a Heart of the Universe, but after absorbing a small portion of its energy, it couldn't absorb any more. The remaining energy would slowly leak out of the body and couldn't be retained. Speaking of which, because it has been a long time, I almost have no impression of this matter."

"Are you saying that the energy of the Heart of the Universe cannot be fully utilized by humans?"

"It seems so. I'm not sure of the specific reasons, maybe it's related to strength? Maybe Lord Green can give it a try, there might be unexpected gains."

Gothner pondered and said, and Green, after hearing this, had a thoughtful look on his face.

However, in reality, Green was not interested in absorbing the energy of the Heart of the Universe. He was much stronger now than before, and could even defeat Gothner with just one finger. Absorbing the energy of the Heart of the Universe probably wouldn't enhance his power much.

But Green suddenly thought of something and continued to ask:

"If that's the case, Clitz shouldn't be able to absorb much energy, right? His goal in snatching the Heart of the Universe should also be to become stronger, right? And Elsa, you seemed to be looking for the Heart of the Universe before, too?"

Elsa, who was next to them, noticed Green looking at her and glanced at Saro Uth beside her.

"It was my grandfather who asked me to find it, and before we set off, he subjected me to inhumane training..."

As she spoke, Elsa recalled the unpleasant memories, and her face immediately became resentful.

Green noticed this and immediately smirked and said, "Don't worry, you'll have plenty of opportunities to get back at him later."

This statement instantly restored Elsa's good mood, while Saro Uth trembled slightly. He stiffly turned his head to look at Elsa and found her staring at him with eyes that seemed to be looking at prey.

"Hey hey hey... I'm your grandfather after all, there's no need..."

"Hmm? Why does that sentence sound so familiar?"

Elsa smiled slyly and leaned closer to Saro Uth.

Only then did Saro Uth remember that Elsa had said something similar to him before, but at that time he couldn't have imagined this day would come, so he naturally ignored Elsa's words.

Suddenly, Saro Uth felt regret for not knowing earlier what he knows now.

"Saro Uth, what is your purpose in seeking the Heart of the Universe?"

"Uh, I wanted to become stronger, although in the end I didn't manage to snatch it..."

"Clitz should have the same goal, right?"

"Most likely."

Green suddenly lowered his head and chuckled. At some point, he had already assumed the posture of a demon king.

"In that case, let's go meet that bunch of bones now."

Feeling the coldness in Green's words, Saro Uth had a gut feeling that Clitz was about to receive a beating.

At this moment, he couldn't help but be grateful that he didn't treat Green as an enemy at the beginning, otherwise...

On Clitz's side, he was still unaware of the impending danger. He ordered his subordinates to guard the surroundings while he hid in the castle, studying the Heart of the Universe.

Although he was curious about the powerful demon king aura from before, with the Heart of the Universe, Clitz instantly swelled with confidence. He could already envision himself becoming the strongest and ruling the entire demon realm.

As for that fleeting aura that came and went, he soon forgot about it.

"Heart of the Universe, what a beautiful crystallization of energy! I can't wait to fully integrate you into my body!" Clitz caressed the smooth texture of the Heart of the Universe in front of him, and upon closer inspection, one would notice several inconspicuous white lines connecting Clitz's body to the Heart of the Universe.

The mist-like energy emanating from the Heart of the Universe floated out and gradually moved towards Clitz's bones, completely merging with them. Every moment, Clitz felt an incredible sense of refreshment. This feeling of absorbing pure energy couldn't be better.

Clitz felt that he was undergoing a transformation. His bones became harder and more aesthetically pleasing, even though he was still a skeleton. "More! I want more! Give me all your essence!" Clitz ecstatically shouted, completely immersed in the embrace of the Heart of the Universe. The infusion of pure energy made him feel comfortable both physically and mentally.

Meanwhile, Green and the others had already begun their actions. "Although we could just walk over there, it would be too laborious. There are teleportation gates between the demon cities. We can use them to teleport to Clitz's territory and also introduce you to the ordinary demons," proposed Saro Uth.

Following Saro Uth's suggestion, Green led the team towards the nearest demon city. Along the way, Green unconsciously transformed into his demon king form. With two horns on his forehead, menacing teeth, and a tail that didn't match his temperament at all, Elsa couldn't resist her curiosity and stole a glance.

But Green quickly noticed and felt embarrassed. After all, his tail was swinging uncontrollably and seemed to have a mind of its own, even moving towards Elsa on its own. Especially with Elsa's excited expression, Green felt that his demon king tail had become a toy...

Fortunately, Elsa hadn't forgotten to teach Green how to control his tail. After trying it on the road, Green could now easily hide his demon features at will. For a succubus like Green, this skill wasn't too difficult.

However, after Green retracted his tail, Elsa seemed slightly dissatisfied. "But on another note, Elsa, you seem so skilled when you're in that state. It doesn't seem like your first time doing that kind of thing."

"Huh?!" Green had remained silent throughout the journey, and the sudden remark caught everyone off guard. Saro Uth coughed awkwardly upon hearing it and quickly distanced himself from Gothner. Elsa also immediately understood what Green was referring to, and the memories from before immediately came to her mind, causing her face to turn red to the roots of her ears.

After two seconds of silence, Elsa blushed and explained softly, "Th-that is... one of the succubus' talents..."

"Huh? There's a talent like that?" Green asked in surprise.

"Yes..."
