Domain-type supreme treasure?!

Another ten days passed, and the vast majority of King-Level Immortal had arrived at Prison No.0021. Wu Yun was also planning to reveal the location of Venerable Nuoqi.

"A Heavy Treasure! King Muchen has a Heavy Treasure!"

A shout echoed repeatedly through the cosmic space. The Monster Race Immortal who shouted was already heavily injured, but he chose to burn his divine power to let out this roar.

Like a thunderclap on flat ground, it swept across an extremely vast area. Spreading sound is much simpler than fighting or interfering with spatial fluctuations; at the very least, it could be heard within a trillion kilometers.

One must know that the safe zone only spanned ten trillion kilometers in total. With the sound spreading a trillion kilometers away, the number of King-Level who could hear it was definitely over ten thousand.

"King Muchen?! A peak King-Level has a Heavy Treasure?"

"The Space-Time Nightmare Beast shouting is King Bujie of the Monster Race. It looks like he is about to die at the hands of King Muchen."

King-Level after King-Level turned their gazes toward the area, and some had already begun flying toward the battlefield. A peak King-Level was not qualified to possess a Heavy Treasure.

Some peak King-Level followed the main force as well. When a Heavy Treasure appears, it is bound to trigger a bloody slaughter, and picking up a couple of World Rings at that time would be a windfall.

The King-Level who dared to roam the Ten Thousand Tribulations Prison now were at least high-level King-Level; low-level King-Level had absolutely no courage to set foot in such an area.

Perhaps there were some in the past, but they left immediately after recognizing the reality.

King Muchen was a peak King-Level from the Bug Race faction. He had been roaming with several friends, but they encountered King Bujie, a member of the Monster Race royal family.

The Monster Race royal family possessed strong combat power by nature. The group fought so hard that King Muchen's faction was scattered and fleeing. In his desperation, King Muchen brought out a Heavy Treasure and a special weapon, instantly killing two peak King-Level.

"Do you think exposing that I have a Heavy Treasure will be of any use?" A miniature iceberg sat between King Muchen's brows, and an endless domain covered the area, making King Bujie extremely uncomfortable.

A pale blue cold mist, like a thin fog, covered millions of kilometers, as if it were about to freeze the entire universe.

The item in King Muchen's hand was actually a domain-type Heavy Treasure!

In his hands, it was enough to suppress a limit-level King-Level, and the flight speed of peak King-Level was slowed down to a mere thirty thousand kilometers per second.

If it were a top-tier domain-type Heavy Treasure, King Muchen might be able to directly annihilate King Bujie by burning his divine body; this was the damage brought about by such a treasure.

A top-tier domain-type Heavy Treasure was too precious, with a value even higher than ordinary supreme treasure armor. It was already an item that could tempt a high-level Universe Master.

An ordinary domain-type Heavy Treasure was slightly inferior, but it could still be compared to the price of a normal top-tier Heavy Treasure.

Swoosh!

Another silver flash streaked across King Bujie's body, the icy aura seeping in and annihilating another two percent of his immortal divine body.

But King Bujie's expression was indifferent; he knew he was certain to die.

Even a Space-Time Nightmare Beast could not escape in front of a domain-type Heavy Treasure. He desperately maintained the Space Lockdown, waiting for other King-Level Immortal to descend upon the battlefield.

Its two heads flickered with light; the golden pupil affected space, and the silver pupil affected time. Only by combining the two and pairing them with a law domain could he barely hold back King Muchen.

Figures flew over rapidly. King Bujie mocked, "King Muchen, I am of the Monster Race royal bloodline. In the future, a Universe Master of my race will reverse time and space to resurrect me. And what race are you? The Canger Race, I believe? Does such a lowly race have a Universe Master?"

King-Level within the Monster Race royal family, especially peak King-Level, would be resurrected by a Universe Master if they fell, whereas those from weak races had to rely on luck.

King Muchen still had a Heavy Treasure on him, but once he died, he would be dead for eternity.

"Kill you, and they won't be able to stop me." King Muchen roared in a low voice, the long halberd in his hand falling violently, tearing King Bujie apart. The special weapon he had used earlier to instantly kill the peak King-Level had already been exhausted.

There were many weapons capable of instantly killing a peak King-Level, such as the Femo Poison of the humans; other races had similar means as well.

The Bug Race had poison personally crafted by the Mother Emperor, which was even more lethal to divine bodies than Femo Poison. The Machine Race had even more weapons; they even possessed combined-attack treasures that could rival Heavy Treasures.

"Hahaha! You won't be able to leave." King Bujie laughed wildly, because other Immortals had already arrived outside the cold mist domain, and space was once again locked down.

Boom!

Following that, King Bujie detonated himself.

A light countless times more dazzling than a Marquis-Level self-detonation emerged. The cosmic space was shattered into countless particles, and the scorching temperature even overwhelmed the endless cold mist.

The power of a peak King-Level self-detonation was terrifying, but those who dared to come to this place to snatch a Heavy Treasure were no weaklings. Standing millions of kilometers away, they stood firm against the ripples of the self-detonation without fear.

King Muchen gathered the cold mist into a circle, tightly surrounding himself.

A domain-type Heavy Treasure? Wu Yun had also quietly arrived near the battlefield. With his Eight-Nine Profound Art, double fifth-level strength, and mastery of the Micro-particle Divine Heart, hiding his figure was far too easy.

He could stand right in front of that group of King-Level, and they would not be able to detect him.

If it were an ordinary chaotic slaughter, Wu Yun would not be tempted by ten billion or a hundred billion Hunyuan.

But an ordinary domain-type Heavy Treasure was worth as much as a top-tier Heavy Treasure.

Even high-level Universe Master would be tempted; most of them only used Heavy Treasure sets.

Whoosh~

As the self-detonation neared its end, King Muchen released the endless cold mist once again, accelerating frantically along the route of the safe zone.

The limit-level King-Level who had come to surround and intercept him changed their expressions. A domain-type Heavy Treasure could maintain a vast range; following behind it meant being slowed down.

Yet King Muchen could maintain high-speed flight.

If this continued, he only needed to fly out of the Ten Thousand Tribulations Prison and reach a place where spatial fluctuations were normal to Teleport away.

"King Citian of my Machine Race is too far away."

"Same for King Zhoutian of my race, otherwise how could we let him run away."

The limit-level King-Level were all filled with unwillingness. If King Muchen's Heavy Treasure had been an attack-type, defensive armor-type, or even a suppression-type, he would not have been able to escape.

Domain-type heavy treasures are simply too powerful.

"Follow him." Some peak kings refused to give up and continued their pursuit.

If they could help their own side's near-invincible kings seize the treasure, they would be rewarded with a massive amount of resources later.

"This damn Space Lockdown is restricting me too." Wu Yun was equally helpless as he followed behind in flight.

The Space Lockdown prohibited his void traversal; unless one reached the level of a Life-Death Dao Lord, where their Dao was so formidable that it could transcend space and time, they could not ignore such a blockade.

Swish!

Streaks of light cut through the Ten Thousand Tribulations Prison, and Wu Yun, having transformed his body into billions upon billions of micro-particles, was still able to maintain sub-light speed flight.

Although the Micro-particle Divine Heart was only a Second-Grade God Heart, it was infinitely wondrous; it could be said that once one truly understood this divine heart, they would almost certainly have the potential to master the Matter God Heart.

Being able to maintain speed while transformed into micro-particles was a testament to Wu Yun's progress in technical application.

The distance between him and King Muchen was closing steadily; the Ten Thousand Tribulations Prison might not have seemed to contain much dense energy, but the difficulty of accelerating within it was extremely high.

King Muchen maintained a speed of 180,000 kilometers per second.

Wu Yun, however, was moving at 270,000 kilometers per second, and the gap between the two was constantly shrinking.
