Ultra: The copy challenge is very simple?

The Dark Ultra Killer raised his head and let out a sharp, strange laugh, and the sound waves tore through the air like millions of rusty saw teeth scraping against metal.

He raised his left arm slowly, and dark purple energy quickly condensed like boiling asphalt, forming a flowing energy shield on the surface of his arm. The shield distorted the surrounding light and refracted strange ripples.

Zero's flying kick with a blazing light came down with the force of thunder. In an instant, the roar of the energy collision shook the earth. The dazzling flash was like a supernova explosion. The glass of buildings within a radius of several kilometers shattered instantly. The shock wave rolled up the rubble on the ground and formed a whistling stone tornado in the air.

Zero's body flew backwards like a meteorite, and when he landed, he plowed two grooves several meters deep on the ground. The violent impact caused spider-web-like cracks to appear on the armor of his left foot. The numbness spread along his nerves like a poisonous snake. He subconsciously frowned and dug his five fingers deeply into the ground to stabilize his body.

On the other side, the Dark Ultraman Killer swung his arms, the sharp blades on his wrist guards still sizzled with electricity, and the air was filled with a pungent smell of burning. The evil light in his eyes became stronger, and the dark energy around him surged and twisted like a living thing, with faint black lightning wandering in it.

At this moment, the two old enemies had the same thought in their hearts at the same time - this guy's power is even more terrifying than the last time they fought! Zero's breathing became heavy, and his chest rose and fell violently. He stared at the powerful enemy in front of him, and memories came flooding back like a tide: that tragic cosmic battle, he exhausted all his energy to defeat the opponent with the Shield of Paraji, and he clearly witnessed with his own eyes that the Dark Ultra Killer turned into stardust and dissipated in the vast universe, but now...

"Why? You were clearly defeated by me!"

Zero's voice was low and angry, with shock and unwillingness that was difficult to conceal, and his silver eyes stared at the Dark Ultra Killer.

The Dark Ultra Killer's chest rose and fell violently, and from it came the screams of countless vengeful spirits. The sound seemed to come from

The deepest part of hell. The dark energy around him surged crazily, forming a huge shadow behind him, like a demon with bared fangs and claws. "I am a combination of resentment!"

His voice was filled with twisted madness, "As long as there is hatred towards the Ultra Warriors in the universe, I will never truly die! Zero, today I will make you pay the price for your past arrogance!"

Before he finished speaking, an inky black energy ball condensed in his palm. Black mist continued to overflow from the surface of the energy ball, and the ground began to carbonize wherever it went.

The Ohkawa Wang inside Zero felt his heart beating violently, as if it was about to burst through his chest. He couldn't help but ask anxiously: "Zero, do you know this guy!?"

"More than knowing him." Zero clenched his fists, the muscles under the armor were as tight as strings, and the bulging blue veins were clearly visible. His eyes were solemn and serious, "He is a collection of monsters and aliens defeated by the Ultra Brothers, and can imitate the skills of the Ultra Warriors. Back then, Taro had to merge into Super Taro to barely suppress him. Even if I won by chance last time, it was also due to the strength of my partners..."

Cero paused, his eyes becoming even darker, "He is now, I'm afraid... Taiga, be prepared, in this battle, we may have to risk our lives."

After saying that, he crossed his arms in front of his forehead, and the head dart slowly rose. The silver blade of light shone coldly in the sunlight, ready to meet the upcoming fierce battle at any time.

The moment the Dark Ultra Killer tore through space and descended, the clouds in the distant sky suddenly rolled back strangely.

Fujiwara Juri couldn't help but be shocked - the dark energy was like boiling asphalt, pouring down through the cracks in the atmosphere, and even the air made a "sizzling" sound as if it was burning.

"This dark force is so strong, far stronger than Saint Deros!" Her voice was trembling uncontrollably, and her knuckles turned white from excessive force.

Haruno Musashi stood up immediately and looked around vigilantly: "What's wrong, Justice?!" Before he finished speaking, the ground suddenly cracked into spider-web-like patterns, and black mist surged out, dyeing the street lights an eerie purple.

"A powerful dark force has descended upon the Earth." Fujiwara Juri's pupils shrank into needle-like shapes.

Asuka Shin has turned into a golden light and soared into the sky. Dyna's signature flying kick cuts through the night sky: "I'll try to contact Zero!"

His consciousness penetrated the ionosphere like lightning, but when it was about to touch Zero's energy fluctuations, he felt a suffocating sense of oppression.

At the same time, Zero is engaged in a fierce battle with the Dark Ultra Killer.

Gravel flew between them like bullets, and the timer on Zero's chest began to flash rapidly. At this moment, Dyna's voice suddenly exploded in his mind: "Zero! Just now Justice discovered that a dark force has descended on Earth. What did you find?"

This moment of distraction cost Zero a price.

Dark Ultra Killer seized the opportunity and knocked it away with his dark purple energy claws.

With a muffled groan, Zero's huge body flew backwards like a kite with a broken string, plowing a hundred-meter-long gully on the ground, and the splashing dust covered half of the sky.

"Discovered? I just happened to meet him and I'm a bit busy now! This guy is very strong!" Zero struggled to prop himself up.

He severed his mental connection with Dyna and refocused his attention on his opponent.

The Dark Ultraman Killer laughed shrilly, and the wails of the vengeful spirits in his chest intertwined with his voice: "I haven't seen you for so long, but your strength hasn't improved much. Your personality has become more arrogant. How dare you be distracted while fighting me!?"

The dark energy around him surged wildly, forming a huge black vortex behind him.

Zero wiped the energy blood from the corner of his mouth and assumed a fighting stance: "It will take you 20,000 years to defeat me!"

“How arrogant!” The Dark Ultra Killer suddenly opened his arms, his left hand spurted out dark energy as thick as ink, while his right hand burst into a dazzling white light.

Two completely opposite forces collided wildly in the air, making a deafening roar.

Zero's eyes widened as he watched in disbelief as the ball of energy began to twist and deform - the figures of the six dark Ultra brothers slowly emerged from it!

Each figure exuded a terrifying aura of oppression, and their eyes flashed an evil red light, as if they were going to drag the entire world into eternal night.

"What!?" Zero's voice was drowned out by the roar of the energy. He clenched his fists, but felt an unprecedented sense of oppression. This battle was far more difficult than he had imagined.
