As Su Bai's voice fell, a black dragon with a length of five kilometers appeared in the gloomy space. Its pair of scarlet vertical pupils were extremely cold and sent chills down one's spine at a glance.

Purple Jade and the other pets looked at it solemnly. This giant dragon did not seem to be very big, but the pressure it exuded was unprecedented.

Five people also appeared with the giant dragon. The leader was Xiao Yulong, an old acquaintance that Su Bai was very familiar with. As for the girl next to him, he also recognized her as Zi Yi, the daughter of Yulong Gymnasium's curator.

"I was wondering who it was; it turned out to be Senior Xiao. What are you doing with such a big army?" Su Bai smiled. He did not really expect Xiao Yulong to enter Abyss Star Territory just to chase him and did not know what kind of method the latter had used to find his exact location.

Moreover, he did not expect that Xiao Yulong had actually found a peak high-level sovereign giant dragon, which was only one step away from immortality.

"I don't want to talk nonsense; I'll give you a chance to hand over the divine skill you acquired in the Blood Moon world. I can let you go alive once you do so," said Xiao Yulong as he narrowed his eyes at Su Bai, not wanting to talk nonsense with him.

"You can just think about how you will leave here alive." He glanced at the new arrival, then looked around, and shouted at the starry space. "Am I right, hidden senior!"

"Huh? Someone else is here?"

Startled, Xiao Yulong's back ran cold. He glanced around and sneered thereafter. "Don't play this kind of despicable trick; you can't fool me."

"This is that guy you said who's very difficult to deal with? He looks foolish and is someone who's very full of himself."

Zi Yi glanced at Su Bai and revealed a trace of contempt. She did not understand why he had to bring a sovereign pet over to deal with such a person. It was a bit redundant in her opinion.

At this moment, a strong voice rang from behind them. "How interesting. You actually discovered me."

Hearing this voice, Xiao Yulong and the others only felt their hands and feet turn cold as cold sweat broke on their backs.

Someone had been right behind them all along!

From beginning to end, they had not noticed even the slightest trace of this person, even with a giant dragon, which was infinitely close to the immortal grade.

Slowly, they turned their heads and looked around. A man in a white suit with purple hair and purple eyes was sitting on a huge amethyst mammoth.

"The undead monster, Amethyst Town Mammoth!"

"You're Dragon King Amethyst, one of the twelve dragon slayers!"

Xiao Yulong's pupils shrank at once; he had not expected Dragon King Amethyst to be here. This signaled trouble for him.

Su Bai's face was also solemn. Sure enough, it was this Amethyst Town Mammoth that had suppressed the space and made his Planet Eye pet unable to teleport away.

Amethyst Town Mammoth was said to be extremely heavy and was born with a strong restraining power, which only grew more terrifying as it grew up. Just by standing here, it could automatically restrain the surrounding space.

Otherwise, normal space blockade could not stop Planet Eye because it relied on electromagnetic transmission, not space transmission, and required very little space power.

This was why he had been so certain about this dragon slayer's presence.

"Senior, I'm Wei Ya's subordinate. Please let me leave with your magnanimous heart and I won't bother your hunting of dragons," he bowed and said with his hands folded.

"You can go, but leave behind your Ancestor Blood Dragon; I'll spare your life on account of Wei Ya," Dragon King Amethyst said with a smile. He originally intended to ambush the Dark Night Dragon, but he did not expect to find the Ancestor Blood Dragon along with it. It really did not take much effort on his part.

With both the Ancestor Blood Dragon and Dark Night Dragon, he could become the fourth permanent Dragon King of the organization and receive a large number of rewards from Black Dragon King. At the thought of this, his heart palpitated excitedly and his mood immediately got better.

"It seems that we have to cooperate, Senior Xiao Yulong." Su Bai turned to look at the other man.

Xiao Yulong had already recovered his calmness at this time. Hearing his words, he nodded. "Give me the Blood Moon divine skill and we can leave here alive. That thing is useless in your hands. After going out, I promise not to make trouble for you again. Deal?"

Su Bai could not help but chuckle. He turned to look at Dragon King Amethyst and said, "Senior, if you kill this Dark Night Dragon, I'll offer you my Ancestor Blood Dragon with both hands."

"You!" Xiao Yulong was furious. "You're digging your own grave!"

"Enough!" A wicked smile appeared at the corner of Dragon King Amethyst's mouth. "You really have no respect for your predecessor. Mammoth, unleash your Gravity Field and Amethyst Chains!"

As his words fell, a purple light burst out, and the invisible force enveloped everyone. Infinite gravity squeezed them down, making it difficult to move. Upon closer inspection, even the surrounding void was squeezed and deformed.

If they were not both high-level Pet Tamers who received strong backfeeding from their pets, they would be unable to bear the pressure.

At the moment the domain was formed, dozens of amethyst-like chains condensed out of thin air and flew toward the Dark Night Dragon, like a series of terrifying purple pythons.

"Roar!"

Facing the Amethyst Town Mammoth, the giant dragon did not dare to slack off and immediately burst forth with full response. It unleashed its Dark Realm and sprayed out its original black Dragon's Breath to attack the amethyst-like chains.

The two attacks collided. Under the influence of the Dark Realm and the Dragon's Breath, these chains were quickly infected and destroyed. Even so, Xiao Yulong's face was still ugly. As the heir to an aristocratic family, he deeply understood the big gap between a sovereign pet and immortal pet.

"The Dark Realm is useful to other attacks but useless in the face of the Gravity Field. Amethyst Chains, Faraway Land!"

Following the order of Dragon King Amethyst, the Amethyst Town Mammoth suddenly transformed into a complete body, becoming a terrifying giant mammoth with a body length of ten kilometers. With a flick of its long nose, it lifted its front legs high and then brought them down fast. Shattering the surrounding void, infinite chains of amethyst descended from all sides of the Dark Night Dragon.

These chains were several times more terrifying than the ones moments ago, and each one was tens of meters thick. The upper part exuded a horrible aura, which banned and suppressed everything.

Looking at the purple chains that had formed a cage from all sides, the Dark Night Dragon panicked. If his master were here, it could continue fighting. Alone, it was no match for an immortal existence.

The immortal grade was an existence that had completely mastered its own original law, and the Amethyst Town Mammoth had mastered the terrifying law of suppression. As long as the opponent was hit by its Amethyst Chains, its spiritual power, including its physical power, would be sealed away. This skill was notoriously difficult to deal with.

"Use your dragon origin skill, Absolute Darkness!" Xiao Yulong suddenly shouted.

"Roar!" Dark Night Dragon did not hesitate, nor did it dare to hesitate. Its wings shook and it let out a roar. Infinite black light came from its body, bursting forth with all its spiritual power.

However, strangely enough, it did not destroy the chains of amethyst but directly rammed against the chains head-on. The chains were shrouded by the black light coming from its body and instantly turned black as if they had fallen into ink.

"Eject your spiritual power." Dragon King Amethyst found that something was wrong and said quickly.

However, it was already too late. In an instant, the Amethyst Town Mammoth turned black and stood motionless on the spot like a statue as if it had been sealed.

This was the effect of Absolute Darkness. It could infect spiritual power and was almost unavoidable. After hitting the opponent, the giant dragon would drag it into absolute darkness and remove all its perception for a period of time. At this time, the Amethyst Town Mammoth could not even feel its owner, Dragon King Amethyst.

"Run quickly!"

Xiao Yulong looked at his dragon, of which the body was entangled with many black chains and the breath had plummeted tremendously. He threw out a crystal, which the dragon swallowed. It then directly tore through the void and took Xiao Yulong and the others into it.

On the other end, Su Bai had already started to escape. He was already thousands of kilometers away at this time, and upon feeling the disappearance of the Amethyst Town Mammoth, he quickly said, "Planet Eye, hurry up and use Electromagnetic Transmission."

Planet Eye, which was always ready, activated the skill to teleport as soon as it received the order.

"Hehe! You want to run? You're overestimating your own abilities!"

A cruel look flashed on the Dragon King Amethyst's face. Although he had miscalculated the power of the Dark Night Dragon's trick, he definitely would not allow these ants to make a fool of him.

An epic-grade contract book exuding a special aura appeared out of thin air. When the pages of the book were flipped, two sovereign behemoths flew out, and in a flash, they caught up with Su Bai, Xiao Yulong, and the others who were trying to escape.

A breath of horror rushed over, and for a while, both could not help but feel a little desperate.

"Despicable!"
