Ultimate: Black Dragon's adopted son, I am the true Demon King!

[Host's "manipulation of minds" behavior has been detected, consistent with villainous conduct. The Great Villain System has been bound!]

......

"You go first."

Duan Yu's eyes flickered with emotion, but he didn't even glance at the Corpse Venerable.

The Corpse Lord didn't say a word in response and simply disappeared.

After confirming that the Corpse Lord had left and that he was the only living person left in the entire villa, Duan Yu finally stopped hiding his emotions.

"The Villain System? Isn't this forcing me to be the villain? Oh well, damn system, you've finally arrived!"

Duan Yu's voice was filled with venting excitement. From the moment he learned that he had transmigrated and been adopted by the Black Dragon, he had been looking forward to his own cheat system.

However, repeated disappointments later made him give up on this idea.

But to his surprise, his system would suddenly appear at this moment.

Although the system's name is not pleasant, for Duan Yu, any system that can help him is a good system.

[Binding successful!]

[New player gift pack has been sent, would you like to open it?]

"Activate".

The mechanical sounds continued to ring out, making Duan Yu even more certain that the voice in his mind was not a hallucination.

[The new player gift pack is now available! Congratulations, host, you have obtained the "Primordial Devouring Heaven Technique"!]

[Primordial Devouring Heaven Technique: Heaven and earth were in chaos, the universe was in primordial chaos! Those who cultivate this technique can devour all energy in the world and transform it into the purest and most powerful primordial energy!]

Duan Yu wasn't particularly clear on what Hunyuan Power was, but if he remembered correctly, the ultimate move used by Xia Tian, ​​who had cultivated the Ultimate Iron Man, along with the other five original-position ability users, seemed to be called Hunyuan Wuji.

The Hunyuan Wuji, which contains the word "Hunyuan," can be used as a powerful move to directly confront the Flame Envoy. Therefore, the Hunyuan Shitian Jue, which also contains the word "Hunyuan," should not be an ordinary item either.

As soon as the system's mechanical voice fell, Duan Yu felt a burning sensation in his dantian.

Concentrating his inner vision, Duan Yu was surprised to find that a black sun had appeared in his previously empty dantian.

The dark outline was faintly visible, like a blurry shadow or a hazy black veil.

Duan Yu tried to project his inner spiritual energy onto the black sun, but the spiritual energy vanished abruptly as soon as it touched the faint outline, as if it had never existed.

Before Duan Yu could show any surprise, his supernatural power erupted on its own without being activated.

It soared to 12000 points in a short time, and then began a precipitous drop.

12000...6000...0!

In the blink of an eye, Duan Yu's combat power index had been reduced to zero, making him no different from an ordinary Muggle.

Under Duan Yu's introspection, the previously still black sun began to repeatedly expand and contract, seemingly undergoing some kind of miraculous transformation.

A few seconds later, the black sun suddenly emitted a black-gold light, illuminating Duan Yu's internal organs. In an instant, a feeling of comfort spread throughout Duan Yu's body, and every cell in his body seemed to be cheering, making him unable to help but let out a groan.

Immediately afterwards, Duan Yu's combat power index began to soar.

0...10000...12000!

Within a few breaths, his combat power index returned to 12000 points.

The original dark green supernatural light, after being devoured and transformed by the black sun, has now turned into a deep black-gold color.

With just a slight movement of his body, Duan Yu felt a booming sound like firecrackers erupting from within him.

"This is the power of primordial chaos? It's indeed quite something!"

Sensing the changes in his internal energy, Duan Yu, itching to reach behind him, grabbed at his back. A green light flashed, and when he pulled it out, a strange weapon that resembled neither a knife nor a ring was already in his hand.

Activating his supernatural power, the green light on the Dragon Slash was instantly covered by black and gold light, completely eliminating the eerie demonic aura from before.

Facing the thick walls of the villa, Duan Yu, wielding the Dragon Slayer Sword, moved.

His knife-wielding movements appeared chaotic, yet they possessed a strange charm, like willow branches swaying in the spring breeze, or poplar catkins drifting in the wind.

If Chen Ming were still alive at this moment, he would definitely be so shocked by Duan Yu's sword-wielding action that he would die again.

Because at this moment, Duan Yu was using the ultimate secret of the Liu family's "Ethereal Blade Technique"—doing whatever he wanted, ethereal and formless!

Chen Ming had been cultivating for a whole year without even getting a grasp of the basics, while Duan Yu had only glanced through it once and had already mastered the ultimate secrets!

A few seconds later, Duan Yu sheathed his sword and stood up, calmly glancing at the thick wall five meters away.

"The power is not bad, no wonder this martial arts manual caught the eye of the Venerable One."

Having obtained what his adoptive father, Black Dragon, had requested, Duan Yu naturally had no reason to stay any longer. With a few light steps, he vanished into thin air.

The pages of the book, turned by the breeze, had just been partially flipped when the specially widened and thickened load-bearing wall suddenly creaked.

Amidst the ear-piercing scraping sound, thousands of knife marks suddenly appeared on the load-bearing wall. The next second, large and small concrete blocks mixed with steel bars fell off one by one, the cuts smooth and flat like a mirror, even vaguely reflecting the shadows of the corpses on the ground.

Without the support of the load-bearing walls, the four-story villa swayed in the wind for a moment before finally collapsing like a pile of blocks, burying all the corpses and making the infamous Wolf Gang a thing of the past.

On his way back to the Armed Tribunal, Duan Yu, who was as swift as a breeze, suddenly stopped in his tracks.

Sensing something was wrong with his body, he focused his mind and looked inward. His heart, which had been perfectly normal before, was now shrouded in a dark green mist, making it particularly conspicuous.

The strangest thing was that this cloud of mist seemed to have a life of its own, slowly pulsating along with Duan Yu's heartbeat, like maggots clinging to bones, always following him.

"This is... an undying miasma? Ha, as expected of my good godfather, he really knows how to prepare for a rainy day! Hunyuan Devouring Heaven Technique, devour it!"

Duan Yu let out a cold snort, and the black sun within his body spun, devouring the lifeless miasma that had been coiling around his heart without offering any resistance.

After a few breaths, the miasma of neither life nor death had transformed into black-gold primordial energy and flowed into Duan Yu's meridians, and the strange feeling in his heart was gone.

12000...13000...14000!

A profound aura flashed across Duan Yu's body, then vanished in an instant, replaced by calm.

"Is it a 2000-point increase in combat power? Not bad, but I'm in a bad mood today. Time to find some fun."

Not wanting to see the black dragon's face anytime soon, Duan Yu stepped onto the asphalt road and vanished in a flash.

........

The Court of Military Tribunal.

"So... Yu'er didn't come back with you?"

Inside the training room, the Black Dragon, dressed in a black robe with a double dragon pattern embroidered on the chest, slightly raised his eyelids and looked at the Martial Corpse Venerable who was reporting back alone. His deep voice echoed throughout the training room.

"Young Master told me to leave first."

The Corpse Lord, with a stiff face and an icy voice, looked like a wooden robot.

"Okay, you can go now."

Black Dragon remained expressionless and waved for Martial Corpse Venerable to leave.

Upon receiving the order, the Corpse Lord's body flashed with dark green light and vanished in the blink of an eye.

"My adopted son has become increasingly arrogant lately. It seems I need to give him a good talking-to so he'll learn his lesson and not forget his place."

He flipped his hand and put away the dark stone that the Corpse Venerable had escorted. A ruthless glint flashed in the Black Dragon's narrowed eyes, and his indifferent tone showed no trace of affection for his adopted son.

.......

"Hmm? Black Cat Hotel? Could it be that Rex has already returned from abroad?"

In the darkness, Duan Yu stopped, his handsome face showing interest as he was drawn to the neon signs across the street.

Without much hesitation, Duan Yu turned around and walked directly towards the Black Cat Hotel.
