A vast and majestic momentum came rushing towards Green and the others, like a tidal wave. Under the pressure of this momentum, Orpheus and Karloffsky struggled to steady themselves. After all, the Black Dragon King was an evil dragon from ancient times who could contend with the Dragon God. Even after so many years, his power remained undiminished, especially after sacrificing Azeral.

Suddenly, the crimson eyes of the Black Dragon King flickered. His gaze hardened, and a powerful pressure targeted Orpheus.

The immense pressure made Orpheus feel suffocated, and his body instantly transformed into a dragon under the tremendous force.

"Do you carry the aura of those old things? If I'm not mistaken, you must be the current Dragon King, right?"

The sentence sounded like a question, but in reality, the Black Dragon King didn't give Orpheus a chance to answer. With a swipe of his forepaw, several dark red light blades swiftly flew towards Orpheus. Without any chance to react, Orpheus was directly hit and flew out at an incredible speed.

"What a waste, you don't even possess the strength of those old things. It seems the Dragon Clan still needs the guidance of the Black Dragon to become strong."

Seeing this scene, Karloffsky beside him dared not even breathe and felt a hint of relief, speculating that he was too weak to attract the attention of the Black Dragon.

But in the next moment, the Black Dragon King turned towards him without even looking at him, and also swung several light blades at him.

Just as the light blades were about to hit Karloffsky, a thick beam of light burst from Orpheus' mouth and blocked the attack.

While doing so, Orpheus warned:

"Karloffsky, leave this place quickly and evacuate the members of the Dragon Clan from the Holy Sanctuary!"

"O-Okay!"

Hearing this, Karloffsky didn't dare to stay any longer and immediately spread his wings to leave.

The Black Dragon King made a motion with his claw but ultimately let it down.

"Never mind, it won't be long before this entire world becomes mine..."

"-Pfft!"

However, before the Black Dragon King finished speaking, Green spat on his face.

"Don't babble on like a dragon vegetable."

"..."

Threads of black aura surged out from the Black Dragon King's skin, evaporating the saliva on his face. His crimson eyes stared at Green and a large amount of black mist started emanating from his body, enveloping the surrounding area within seconds, sealing it off into a small region.

"In ancient times, my few were no match for the many, and I was sealed by your Dragon God. But this time, without those old things, do you really think you can survive in my hands...?"

As he spoke, his momentum grew even stronger, and Green could clearly feel that the Black Dragon King's aura was different from anyone he had encountered before.

It wasn't just a drop in the ocean; it was a difference between heaven and earth.

In this aura, Green caught a faint scent similar to the source energy.

"...!"

This unexpected discovery made Green slightly more serious than his initial playful attitude. He not only recalled Orpheus's earlier account, that the Black Dragon King possessed immense power because he had consumed a fruit cultivated by the Supreme God, but also speculated that there might be a connection between that fruit and the world's elemental energy.

The Black Dragon King obviously noticed the change in Green's expression and felt puzzled.

Why did this human not show a trace of fear in his eyes, but instead... excitement?

For a brief moment, the surprise in the Black Dragon King's eyes suggested that the excitement in Green's gaze only appeared after he revealed his power.

But it was just that.

"I am no longer who I was in the past. Even if you were to summon twice the power of those old things, I will not suffer the same fate as before."

Casting aside the absurd emotions in his mind, the Black Dragon King's voice lacked any emotion. He lightly lifted his black claw and aimed it at the unmoving Green, ruthlessly slashing down as if he could already envision Green being dismembered.

As the dark red sharp blades were about to attack, Yuzuriha, who was very close to Green, remained calm because she knew that such meager power was not enough to catch Green's attention.

Green effortlessly waved his hand, as if shooing away flies, and several dark red blades immediately stopped in their tracks, then shattered into fragments and disappeared in the air.

In the next moment, the Black Dragon King felt his vision blur, and when he regained his senses, Green had already disappeared from his sight.

The Black Dragon King felt a sense of unease. He hadn't seen how Green moved just now, but his fighting instincts prompted him to react quickly.

Dark red beams of light shot out from the Black Dragon King's mouth, aiming upwards, but Green easily dodged by sidestepping slightly. Then, with a sudden burst of speed, Green's arm swung in and out, blinding one of the Black Dragon King's eyes.

Without giving the Black Dragon King a chance to catch his breath, Green, in the moment the Black Dragon King couldn't even scream, swiftly struck with a powerful chop, directly severing several of the Black Dragon King's fangs.

Intense pain instantly spread across the Black Dragon King's face, making him feel a burning sensation.

Ophir observed from the side throughout, and seeing Green's clean and precise techniques, he couldn't help but feel a sense of fear and relief that he didn't provoke Green too much in the past. Otherwise, it wouldn't have been as simple as getting injured.

After this attack, Green quickly retreated, creating distance between them. For Green, even if he carried out this action with Yuzuriha, it was no pressure at all.

"I don't know what you were like before, but seeing how weak you are now, you must have been nothing special before," Green taunted. Although he wasn't a ruthless person, he found enjoyment in mocking others, especially when faced with someone who was overly confident.

In the past, the Black Dragon King might have been intimidated by such taunts, but now he remained unfazed.

Green quickly noticed something unusual. From the wound that the Black Dragon King had sustained, a faint black mist emerged like water vapor. The wound on his head also quickly healed at an astonishing speed, restoring his comical face that had lost a few fangs. His eyes regained their brightness, as if nothing had happened.

Ophir was also astonished, his dragon face looking unusually odd.

Even Green furrowed his brow slightly, beginning to realize that this Black Dragon King might not be as superficial as he appeared.

The Black Dragon King narrowed his eyes, emitting a dangerous gleam.

"I find it amusing to see how surprised you all are. The gap between me and you is like heaven and earth. After using the power of that human called Ezrael, I have successfully obtained the forbidden power of immortality. In other words, I am now an invincible dragon who cannot be killed!"

Initially, the Black Dragon King established contact with Ezrael through some means, bestowing a small fraction of his own power and some of his subordinates upon Ezrael.

Although it was only a very small portion, not even one-thousandth, it was enough to ensure that Ezrael would survive in any extreme situation.

The price was that once Ezrael finished creating the ultimate soul medicine, he would have to give a portion to the Black Dragon King.

This ultimate soul medicine was the true elixir of immortality, but it required a large amount of spiritual power or the sacrifice of the user's soul to create.

In reality, neither of them had any intention of keeping the agreement. The Black Dragon King used Ezrael to observe the current world's situation, and when the time came, he would take control of Ezrael's body to create the ultimate elixir of immortality. Ezrael, on the other hand, used the Black Dragon King's power to barely prolong his life. Once the ultimate soul medicine was completed, he would conquer the Black Dragon King and the entire world.

However, Ezrael never expected that the Black Dragon King, whom he wanted to use, had the same ideas as him, and more importantly, he took action first.

When he recalled the struggle of Ezrael's soul not long ago, the Black Dragon King felt a sense of satisfaction.

"How pitiful, humans."

"..."

Ezrael.

When this familiar name came out of the Black Dragon King's mouth, Green could already guess Ezrael's fate, although he didn't expect it to happen so suddenly.

Thinking about this, Green couldn't help but smile.

"I didn't expect that guy to be so capable. I underestimated him."

"Do you also know that human? ... Oh, right, I remember now. That human summoned one of my subordinates not long ago. If I'm not mistaken, the death of my subordinate is indirectly related to you, right?"

"That's right. Even if I wasn't standing here today, you would still come to me for a beating."

The Black Dragon King's aura suddenly turned cold, and the temperature around him seemed to drop to freezing point.

He didn't expect Green to dare speak so arrogantly after witnessing his regeneration ability.

"What an ignorant human."

Hearing these words, coupled with the scene in front of him, Ophir suddenly had a sense of déjà vu.

Isn't the current Black Dragon King the same as himself when facing Green in the past?

As for the outcome...

"Crack!"

The sound of something piercing through flesh entered their ears, accompanied by dark red blood that closely resembled black.

While the Black Dragon King was still coldly ignoring Green, Green made a swift and precise attack, creating a hole in the Black Dragon King's abdomen.

It wasn't until a hot stream of blood flowed out from his body that the Black Dragon King realized he had been injured.

"Ah!"

Following the pain that burned like fire, just like last time, in a matter of seconds, the Black Dragon King's body fully recovered and his state did not diminish in the slightest.

With a renewed gaze of fury, the Black Dragon King stared at Green. Being humiliated repeatedly had resulted in him no longer being able to contain his anger.

"Human, don't be so arrogant. I've already said I am immortal!"

A dragon's roar resonated in their ears. The Black Dragon King's agility and his colossal figure formed a great contrast, unleashing attacks on Green dozens of times in the blink of an eye.

Unfortunately, Green was no pushover. Despite the vast difference in size, he was still able to dodge and counterattack.

The two turned into afterimages, and dangerous beams of light occasionally shot out in all directions.

Green remained completely at ease throughout, while the Black Dragon King's attacks kept missing, giving him the feeling of punching a cottonball with no force behind it.

It may sound shameless, but he was starting to shift his focus onto Yuzuriha and Ophir, who were not far away.

However, just as this thought arose, his head was struck by a heavy blow, the tremendous force causing his head and body to fly off.

"At least you, as the leader of those flying insects, should have some dignity."

Green naturally knew what the Black Dragon King was thinking and mercilessly taunted him, while also inflicting physical blows.

Though Yuzuriha and Ophir couldn't hear their conversation, they could see the intense battle from the rough afterimages.

But it seemed like the Black Dragon King was completely outmatched?
