The item used by the Minotaur to escape is a unique teleportation item in the Demon Realm, which can teleport Demon beings to the Demon Realm at an extremely fast speed, even if they are not powerful enough to break open space.

Elisa also has the same item, and its effects are much better.

However, when Green discovered that after using the teleportation item, he and Elisa were trapped in a dark space, he immediately realized that the so-called speed was relative.

"If I had known it was this slow, I would have just opened the space myself..."

"But you don't know the coordinates of the Demon Realm, so it's not easy to accurately reach the Demon Realm, right? Besides, the Demon Realm is also very large, what if we get lost..."

Hearing Green's dissatisfied mumbling, Elisa weakly refuted a few times.

Upon careful consideration, Elisa's words did make sense.

Although Green had the experience of pulling Salo Uth out of the Demon Realm directly, his attention was focused on Salo Uth at that time, not the coordinates of the Demon Realm. Moreover, being able to catch Salo Uth had partially to do with him actively opening the passage between the human and Demon realms, so Green now does not have a hundred percent certainty in accurately opening the entrance to the Demon Realm.

It would be awkward if something unexpected happened and they couldn't find the escaped Minotaur.

"But speaking of which, what exactly is The Heart of the Universe?"

"I'm not very sure either, but my grandfather said it is the purest energy in the universe. Any object that obtains the energy of The Heart of the Universe can become extremely powerful."

"So your grandfather wants to become even stronger?"

Elisa nodded gently, and Green couldn't help but furrow his brows, looking like he was pondering deeply.

Green clearly remembered that the Demon King Salo Uth was already very powerful, even approaching the power of a god. Why did such a powerful entity want to become even stronger?

As a being far stronger than Salo Uth, Green expressed that he really couldn't understand.

Seeing Green's look, Elisa lowered her head and remained silent for a moment, as if reminiscing about something.

"In fact, the Demon Realm does not have just one Demon King. Including my grandfather Salo Uth, there are three Demon Kings in total."

"Three?"

Elisa nodded.

They are the Demon King Salo Uth that you know, the master of those Minotaurs - the Skeleton Demon King Clitz, and the last Demon King named Gothney."

"Completely different from what I imagined... Among these three Demon Kings, who is the strongest? Is it your grandfather?"

"No, the strongest is the Demon King Gothney."

"Gothney?"

Elisa nodded again, and then explained in detail what she knew to Green.

Among the three Demon Kings, Demon King Gothney is the strongest in terms of individual strength, and also the most eccentric. It is said that Gothney has been constantly eating since birth, even in battles where he could count the fingers on one hand, Gothney never neglects his meals.

What is most frightening about this is that when Salo Uth was young and challenged Gothney, he was beaten back to his lair by Gothney, who had his mouth full of food.

The title of the strongest Demon King Gothney was therefore firmly established.

As for the other Skeleton Demon King, its individual strength is not particularly strong, but Demon King Clitz has the most subordinates among the three Demon Kings, with the most powerful forces in the Demon Realm.

It's hard to say who would have the last laugh if a war broke out between the three sides.

At the same time, the transfer of The Heart of the Universe in the Demon Realm also caught the attention of the three Demon Kings.

The Skeleton Demon King Clitz was the first to realize the existence of The Heart of the Universe.

After confirming that The Heart of the Universe was headed in his direction, Clitz laughed heartily.

"With The Heart of the Universe, the entire Demon Realm will be under my control!"

Clitz has always been the weakest Demon King in terms of individual strength among the three Demon Kings, but with The Heart of the Universe, it's different. As long as he assimilates the energy of The Heart of the Universe into his body, he can definitely surpass the other two Demon Kings and become the strongest existence in the Demon Realm.

At the same time, Clitz also understood that other demon kings would definitely come to snatch The Heart of the Universe after feeling its energy. Therefore, Clitz not only sent his subordinates to welcome them, but also eagerly joined the battle himself.

He was determined to seize The Heart of the Universe.

Salo Uth also felt the presence of The Heart of the Universe, but he did not rush to go because he sensed that Elsa was already moving quickly. He also felt a familiar aura.

"I didn't expect that The Heart of the Universe would even attract Green. This is getting interesting!" Salo Uth exclaimed.

Shortly after, Salo Uth and his group met up with Elsa.

On the other hand, the demon lord Gothney had a completely different attitude. While he could sense that The Heart of the Universe was getting closer to the demon realm and had even entered the spatial zone, he couldn't care less about it. All Gothney cared about was having food. As long as he had an endless supply of food, he was content for the rest of his life.

His subordinates also didn't take any action and continued to take turns providing Gothney with food as usual.

At this moment, Elsa suddenly thought of something and turned to Green, saying, "Green, before we enter the demon realm, there's something I must remind you of."

"What is it?" Green asked.

"Although you are very powerful, the power of the demon race will greatly enhance in the demon realm, while non-demon creatures will have their powers limited. So, I hope you will be careful in your actions," Elsa said with a serious expression.

Green looked at Elsa, surprised by her words. He had never realized that there were such limitations in the demon realm.

"Are you saying that the power of the demon race weakens when they leave the demon realm?" Green asked.

"...Although it's not entirely accurate, you can understand it that way."

"Oh..."

Elsa's words surprised Green. If that was the case, then Salo Uth, who had fought him in the human realm, had never truly unleashed his full power? Green was genuinely curious about Salo Uth's true strength. Moreover, it seemed like there was an even stronger demon lord than Salo Uth.

Thinking about these things, Green's excitement grew.

Seeing that Green didn't seem worried at all but rather happy, Elsa was puzzled. "Aren't you afraid? If you get killed in the demon realm, I won't be able to save you."

"What is there to fear? I'm actually quite curious about what will happen in the demon realm. I hope the strength of the three demon lords won't disappoint me."

Elsa looked into Green's eyes and saw a blazing fighting spirit. She couldn't help but sigh, realizing that Green was indeed not an ordinary person.

Not long after, Elsa noticed that they were about to reach the demon realm. She reminded Green once again, "We're almost at the demon realm. Be aware of the rejection you may face in the demon realm and be careful not to get killed."

"Huh? How could it be that simple—uh?!" Green was about to say that Elsa was overthinking it when he suddenly felt an indescribable pressure, and his expression turned shocked.

Seeing Green's expression, Elsa also showed concern. "Hey, are you okay? If you're not, then don't go to the demon realm."

"I'm fine." Green took a deep breath, and although his shocked expression had not yet subsided, he felt the pressure on his body increasing.

Seeing Green like this, Elsa was about to continue persuading him when she suddenly heard Green saying in disbelief, "I never thought this pressure would be so weak..."

"Huh... What did you just say?"

"I said I never thought this pressure would be so weak. The pressure I felt just now should be the rejection from the demon realm, right? It feels like a few girls surrounding me and squeezing me tightly. It's really unexpected."

"……"

Green's amazement and movements left Elsa at a loss for words.

However, upon closer observation, it could be seen that although there was astonishment on Green's face, there was no trace of resistance. It was clear that the weak pressure from the demon realm had truly surprised Green.

But Green's choice of words truly left Elsa speechless.

What kind of experiences had he gone through to come up with such a twisted description...

In any case, the two of them successfully passed through the barrier of the demon realm and broke into its interior.

After entering the demon realm, the subtle pressure on Green disappeared, but he could feel an additional layer of restraint within his body, suppressing his strength by more than one level.

However, Green remained unfazed. Compared to the strength he possessed, the suppression was just a drop in the bucket.

Furthermore, although Green had expended a lot of energy during his previous attempt to save his parallel self, he was still constantly replenishing energy, just as before.

Even though the demon realm was suppressing the energy within Green's body, it did not hinder the growth of his power in the slightest.

After entering the demon realm, the first thing Green did was release his senses and gain a preliminary understanding of the realm.

In an instant, numerous auras that were distinctly different from those of humans and monsters appeared in Green's senses. Some were strong, some weak, but all were clearly much stronger than ordinary humans.

Unfortunately, within the demon realm, Green found that his senses were restricted. He couldn't expand his senses as freely as in the human realm.

But even so, Green still sensed a group of powerful auras moving rapidly in the distance. Among them, there was one aura that stood out from the rest.

"It seems like the Minotaur Demon has arrived in the demon realm before us, but you inflicted serious injuries on him. With our speed, it won't be long before we catch up to him!"

Elsa optimistically said after sensing that the Minotaur Demon's speed had clearly slowed down.

However, after careful observation, Green found that the Minotaur Demon's aura was rapidly closing in on the group of powerful auras. At this rate, it was likely that the two would converge before Elsa.

Although it wasn't clear what faction the group of auras belonged to, the most likely possibility was that it was the reinforcement called by the Minotaur Demon.

Therefore, Green immediately poured cold water on Elsa.

"It's no use catching up. That guy is probably already gathering with his companions. Even if you go after him, you'll probably just be beaten up."

"Eh?! What should we do now then? If I don't get The Heart of the Universe this time, my grandfather will..."

"What will he do?"

"He'll beat me up... Sob..."

Green couldn't help but conjecture just how heartless Saro Uth must have been to make Elsa react like this.

"Alright, alright, stop crying. I didn't come here to be a useless person. Let's go together."
