High-level martial arts: Contract cashback, invincible starting from the Zerg.

After eliminating hundreds of mechanical mercenaries and two Darkin snipers

Wearing the Nightmare Demon-Slaying Armor, Rising Sun Winter came to Chen Feng's side.

At this moment, Chen Feng had already removed his Heavenly Rank Zerg armor. His calm eyes were fixed on the deep passage leading to the main control room, as if he were deducing something.

"What are you thinking about?" Xu Ri Dong Cuo asked.

Chen Feng raised his hand and pointed forward.

As if provoked by Chen Feng's words, the previously faint sense of intimidation in the deep passage suddenly surged, and cold, viscous dark energy slowly seeped out along the metal passage.

Those were the auras of three Earth-rank Dark Descendants.

Even from a distance of tens of meters, it can send chills down your spine.

"When I was using the Zerg armor just now, my perception range doubled, so I was able to sense that there were three Earth-rank Darkborn in that passage."

"With your aura, you're probably not much different from a Heaven-rank expert. Why would you be afraid of three Earth-rank experts?" said Xu Ri Dong Cuo.

"I used up too much of my demon-controlling energy when dealing with the Azure Water Dragon King, so I'm afraid I can't handle those three people inside now," Chen Feng said calmly.

Just then, the darkness in the deep passage seemed to be torn open by an invisible hand, and three figures walked out of the dark passage unhurriedly.

There was no sudden attack, nor any ferocious roar like that of a strange beast.

However, with each step they took, it seemed to cause a layer of chilling frost to rise from the alloy floor beneath them, and the cold, viscous power of the Dark Ones spread out in layers.

It was as if even the light itself was willing to bow down to these three Earth-rank Darkborn.

The three Earth-rank Darkborn were all dressed in fitted black robes with dark patterns, the collars and cuffs embroidered with the Darkborn's unique thorn emblem.

The leader of the Dark Ones was tall and slender, with a pale face as hard as a sculpture. His narrow, dark eyes were devoid of any emotion, and the dark purple lines at the corners of his eyes added to his aloofness. When his gaze swept over Chen Feng and Xu Ri Dong Cuo, he was as calm as if he were looking at two lifeless corpses.

The two female Darkin beside him were almost as indifferent as he was, as if they were following the old Darkin's code of conduct, even their breathing frequency and the arc of their drooping arms were almost completely synchronized.

The next second, the three of them simultaneously raised their hands from their sides, their pale, slender fingertips steadily supporting the red thorn necklace.

The leader of the Dark Ones twitched his fingertips first.

The fingertips gently brushed across the thorn necklace.

The scarlet runes on the thorn necklace suddenly lit up with an eerie blood-red light, instantly forming a massive triangular energy array above Chen Feng and Xu Ri Dong Cuo.

"It's the Three-Body Blood Curse Technique." Xu Ri Dong Cuo rarely showed a solemn expression.

"It's the Red Thorn Necklace." Chen Feng frowned as well.

The Golden Thorn Necklace features three-dimensional control, enabling a four-dimensional complete blockade of the target's physical movements and spatial displacement.

The Crimson Thorn Necklace is a Blood Curse Enhancement. It continuously drains the opponent's energy with Blood Curses, disrupting their Source Energy flow and continuously strengthening the Darkin's combat power.

Chen Feng checked the energy of the Vajra Core. Due to the previous two major battles, the Demon Slayer's energy had been reduced to 25% of its total energy.

Even if he could summon the Golden Demon Armor again, he still wouldn't be able to deal with three Earth-rank Darkborn.

Chen Feng immediately discussed tactics with Xu Ri Dong Cuo through the Lucky Contract System.

Chen Feng: "We can only use luck to strengthen ourselves and finish this quickly."

Rising Sun in Winter: "Isn't that a bit wasteful?"

Chen Feng: "Then what else can we do?"

Rising Sun Winter Mistake: "Besides the Lucky Contract, you don't have any other contract systems?"

Chen Feng: "Huh? You mean the sub-contract system? I only have a contract with one demon lord."

"A demon lord!?"

Xu Ri Dong Cuo looked at Chen Feng with a somewhat blank expression, as if he had heard something unbelievable.

"No!! You've made a contract with a demon lord, so why aren't you summoning him now??"

......

When Karendius Ash lazily emerged from the chasm of purgatory.

Pale purple flames kept rising from the ground he walked on. The infernal flames that burned away souls obediently spread along the edges of his shoes, but dared not even burn a single piece of his clothing.

This made Karendius Jin appear as if he had strolled out from backstage at a top luxury fashion show, effortlessly overshadowing everyone else.

"Isn't this an oversized leather trench coat?" Xu Ri Dong Cuo murmured in surprise as he looked at the demon lord before him.

"You have good taste, kid." Karendius Jin casually flicked the lapel of his long trench coat with his fingertips, and a wisp of pale purple infernal fire leaked out from between his fingers and shot out instantly.

On the contrary, it made the matte cowhide look even more textured.

"Senior, are the clothes from this brand not readily available from the Great Xia Kingdom?" Xu Ri Dong Cuo asked.

"No, it's a unique edition from Purgatory Handcraft Workshop, made of top-grain Abyss Demon Bull leather, with stitching made from the tendons of Fallen Angel tail feathers. It won't wrinkle in the wind or be cut by a knife. Most importantly, it can suppress my Purgatory aura." Karendius Ember smiled.

The chasm of purgatory slowly closed behind the demon lord.

A cigar appeared in Karendius Ash's hand, but his golden demonic eyes were fixed on Chen Feng.

"How so, little one?"

"We've met our match, senior. We'll need your help," Chen Feng said.

"Oh? You've met your match?"

The cigar on Karendius Jhin's fingertips instantly glowed with a dark flame, and Karendius Jhin followed Chen Feng's gaze to look at the three Darkin in front of him.

"So it's those Darkin brats again. Fine, I'll do this favor for free!"

At this moment, the old Darkborn, who was activating the Red Thorn Necklace, suddenly turned deathly pale.

He originally intended to use the Blood Curse Domain to disrupt the source energy of the two demon slayers.

However, the moment Karendius Ember looked at himself, the red thorn necklace in his hand seemed to have its energy source choked by an invisible hand.

Not only were the blood curse runes completely extinguished, but the blood curse matrix that had already formed also disappeared.

In an instant, fine cracks began to crawl all over the surface of the Blood Curse Necklace, as if it would shatter completely at any moment!

That was not a suppression on the level of physical or mental strength.

Rather, it is an absolute and comprehensive crushing defeat at the level of race and bloodline.

The three Earth-rank Darkborn were powerless to resist the bloodline suppression of Karendius Ash. Their shadow energy was like frozen stagnant water, unable to move even a fraction.

After suppressing the three Darkborn with absolute bloodline power, a smile appeared on Karendius Jin's lips, and the rift leading to Purgatory reopened.

"Kids, I've weakened their blood curse abilities for you. Now it's up to you two to see what you're capable of."
