Ultra: The copy challenge is very simple?

"Diabolo!" Regulus roared, like an enraged lion, and rushed forward, engaging in a fierce battle with Diablo.

Regulus first hit Diablo's face with a swift straight punch, trying to gain the upper hand with strength. However, Diablo easily raised his hand to block the blow, without even a flicker on his face.

Regulus was not discouraged. He quickly adjusted his posture and kicked Diablo's abdomen with his left leg like an arrow. Seeing this, Diablo raised his leg to defend without hesitation.

Bang! The two legs intersected, making a deafening sound, and the air seemed to be filled with a strong smell of gunpowder. However, Regulus's attack was firmly blocked by Diablo, who even snorted coldly, appearing to be at ease.

Regulus's eyes were stern. He knew that his opponent should not be underestimated. So he launched another attack, bending his five fingers like claws and fiercely grabbing Diablo's vital parts. In this attack, he gathered all his strength, hoping to subdue Diablo in one fell swoop.

However, Diablo showed amazing speed and flexibility. His body moved at a strange and unpredictable speed, as if he could predict every move of Regulus. Regulus's attacks missed again and again, and his eyes gradually revealed surprise and confusion.

Whoosh! Whoosh! Whoosh! Diablo's body was like a ghost, moving freely between Regulos' attacks. No matter how hard Regulos tried, he couldn't touch even a corner of Diablo's clothes.

Regulus couldn't help but exclaimed: "What's going on? I can't even hit this guy?" His voice was full of disbelief and frustration. This battle was much more difficult than he had imagined.

"Haha!" Regulus roared, and quickly gathered energy in his hands, firing a hot red ball of light, which rushed straight towards Diablo with blazing flames.

Diablo dodged the powerful ball of light with a quick sidestep, a teasing smile on his face: "Tsk tsk tsk, Regulus, you're no good either. Your moves are gorgeous, but if you can't hit the enemy, they're just a circus!"

Hearing this, Regulus's face darkened and he retorted, "Don't underestimate me!" Before he finished speaking, he suddenly jumped up like a vigorous eagle and soared into the sky. In the air, he quickly spun his body, and his legs began to accumulate blazing flame energy, like a red dragon about to spit fire.

"Red Dragon Flame Kick!" Regulus roared, and the flames on his legs became even more intense, like a burning fire dragon, rushing towards Diablo with destructive power.

However, at this moment, a mysterious beast emblem suddenly appeared on Regulus' arms, and in the blink of an eye it magnified several times. It was a white tiger pattern, which complemented the red dragon and appeared in Diablo's sight together.

"Electric White Tiger Kick!" Regulus shouted again, and the energy of the two cosmic mythical beasts - the red dragon and the white tiger - instantly merged into his legs, making his kicks even more powerful.

"Red Dragon and White Tiger Kick!" Regulus perfectly combined the energy of the two mythical beasts with his own flying kicks and rotating power. This attack was simply extraordinary, as if it could tear apart the space and destroy everything.

However, facing such a terrifying attack, Diablo was still not afraid at all. Instead, he sneered: "I see, combining the power of the Red Dragon and White Tiger Fist with the power of the flying kick is really creative. But if you think you can defeat me with just this move, it's ridiculous!"

Before he finished speaking, Diablo also leaped forward, his legs tightly wrapped in dark golden energy, as if he was wearing a layer of indestructible armor.

"Absolute Flying Kick!" Diablo shouted, and kicked towards Regulus in mid-air with endless destructive power.

The two attacks met in mid-air, as if a red meteor and a dark gold meteor collided with each other, erupting in dazzling sparks and a deafening roar.

Boom! ! A loud noise was heard in the air, as if even the heaven and earth were shaken by this force. Smoke and dust rose up, energy waves scattered, and the figures of the two people were looming in the explosion.

But soon, a figure fell from the sky like a kite with a broken string, and hit the ground heavily.

Boom! !

With a dull sound of falling to the ground, the dust was instantly stirred up, forming a blurry smoke. When the smoke dissipated, Diablo was seen standing firmly in the same place, while Regulus was deeply trapped in a pit, looking a little embarrassed.

However, Regulus did not give up. He quickly struggled out of the pit and stared at Diablo in disbelief, with shock and confusion in his eyes.

"Is this guy really Diablo? He has become so strong?" Regulus muttered to himself, his tone full of disbelief.

After hearing this, Diablo dusted himself off and a disdainful smile appeared on his lips: "What's wrong? Regulus, is this all you can do? You fell down before I even got serious. It seems like you're not that good either!"

Facing Diablo's ridicule, Regulus suddenly laughed. He wiped the blood from the corner of his mouth, and his eyes were full of fighting spirit again: "I'm not serious, Diablo. I didn't expect you to be so powerful, but I can't be underestimated!"

After saying that, Regulus leaped again, and the mythical beast emblems on his arms suddenly appeared, flashing with dazzling light. Then, he kicked his legs hard, and a terrifying energy mixed with flames and lightning burst out from it, like two violent dragons, rushing straight towards Diablo.

Diablo snorted coldly, and punched out with his backhand. The wind from his fist was as sharp as a knife, instantly blasting the mixed energy into pieces. The smoke from the explosion quickly spread, blocking Diablo's sight.

However, Diablo was not flustered. He looked around, his eyes revealing a calm and disdainful expression: "Too naive, Regulus. You think you can beat me with this method? Do you think I'm an idiot!?"

Diablo flashed, keenly aware of the danger behind him. He turned around and met Regulos's determined shout.

"The secret of the Cosmic Beast Fist? The powerful Bull-breaking Fist!" Regulus' voice echoed on the battlefield like thunder. Then, a huge red bull energy emblem roared from behind, carrying unparalleled power, and went straight to Diablo's chest.

Facing this unstoppable blow, Diablo laughed. His laughter was full of desire for battle and respect for his opponent. "It's finally here. The Strong Power Breaking Bull Fist is known as the strongest secret of the Universe Fantasy Beast Fist. I want to see how much of your strength you really have as the strongest universe fantasy beast!"

As he spoke, Diablo's eyes flashed with determination. He raised his right fist, and dark golden absolute energy began to gather in his fist, as if to condense the power of the entire universe into this fist.

"Absolute Energy Fist!" Diablo roared and swung his punch. A dark golden energy wave shot towards the Red Bull Energy Emblem like an arrow from a string at an astonishing speed.

Whoosh! !

Boom! !

The two energies collided violently in the air, making a deafening roar. The dark golden energy light waves and the energy emblem of the Strong Force Breaking Bull Fist intertwined and competed with each other, and neither was willing to give in.

The powerful impact force generated by the energy collision even triggered lightning in the sky. Dazzling flashes of lightning flashed on the battlefield, illuminating the figures of the two people confronting each other.

Zizi! Zizi! Zizi! The roar of lightning and the collision of energy intertwined together, forming a shocking picture. This battle was no longer just a contest of strength and skill, but also a collision of will and faith.

Lightning struck the ground like an angry dragon, stirring up layers of dust and shrouding the battlefield in chaos. When the dust cleared, the figures of Diablo and Regulus were seen like two meteors, desperately approaching each other, and finally colliding at the most intense moment.

Bang! !

Accompanied by a deafening explosion, Diablo and Regulus were both knocked back by the powerful impact, and each staggered for a few steps before they could barely keep their balance.

Diablo shook off the dust on his body, a trace of disdain flashed in his eyes: "Is this the legendary Strong Bull Breaking Fist? It feels just like that! It seems that your so-called strongest universe fantasy beast fist is just like this."

Before he finished speaking, Diablo's whole body suddenly surged with stronger dark golden energy, and his eyes flashed with excitement: "Since you have used the Space Monster Fist, then in response, I have to use my Space Monster Fist to return the favor to you!"

Upon hearing this, Regulus's expression became even more solemn. He knew very well that Diablo's strength should not be underestimated, and he also understood that the power of the Space Monster Fist was not to be underestimated.

"I didn't expect that Diablo's current energy alone could match my Strong Bull Breaking Fist." Regulus secretly marveled in his heart, and at the same time, he looked at the enemy in front of him more vigilantly, "This guy hasn't even used the Space Monster Fist yet? Then how terrifying is his true strength?"

On the battlefield, the atmosphere became tense and depressing again.

"Space Monster Fist? Super Vibration Wave Fist!"

Diablo's roar resounded through the sky, and he clashed his fists together suddenly, creating a deafening roar.

Under the horrified gazes of Regulus and the onlookers, a huge Gomora energy shadow slowly emerged behind Diablo, its horns flashing with dark golden light, as if it contained the power to destroy the world.

Immediately afterwards, Diablo swung out with both fists, and the dark golden super shock wave energy condensed into an extremely powerful energy fist, which, with a roar, hit Regulus directly like a meteor.

Seeing this, Regulus looked solemn and immediately spread out his hands, using his own energy to quickly weave a rotating umbrella-shaped shield, attempting to use the force of rotation to dissolve this powerful attack.

Boom! !

A strong collision sound suddenly exploded, echoing on the battlefield like thunder.

The dark golden energy fist slammed into the umbrella-shaped shield, bursting out with dazzling light, forcing Regulus to retreat repeatedly, and the ground beneath his feet shook due to the huge impact force.

Boom! After holding on for just a few seconds, Regulus's umbrella-shaped shield finally couldn't bear the weight and shattered with a loud bang, and the scattered energy fragments bloomed like fireworks.

As a result, Regulus was also affected by the force and staggered back several steps, his face slightly pale.

"Hahahaha, come again!" Diablo laughed wildly, his desire to fight even stronger.

He spread his hands again, and this time, what appeared behind him was Gudun's energy shadow. The ferocious face and waving whips made people feel cold.

"Painful Whip Fist!" Diablo shouted in a low voice, and the energy shadow of Gudun seemed to have heard the call of its master. The whips in both hands swung violently, and with a whistling sound of breaking through the air, it lashed towards Regulus fiercely.

Whoosh! !

Two sharp sounds cut through the air, Regulus' eyes flashed, and his figure dodged to the side quickly like a ghost.

Almost at the same time, the two whips hit the ground fiercely. Bang! With a loud noise, two deep scratches were instantly made on the ground, as if they were cut by a sharp blade, shocking to the eye.

"Tera Fireball Fist!" Diablo's roar was as hot as a flame. The energy shadow of Zetton behind him seemed to come alive, and his arms gathered dark golden energy, condensing into a dazzling fireball.

Whoosh! !

The fireball streaked through the air like a meteor, whizzing towards Regulos with destructive force. Regulos had just avoided the attack of the Painful Whip Fist, and before he could stand firm, he was faced with this sudden crisis again.

"Hmph, it's not that easy to defeat me!" Regulus snorted coldly, and the phantom beast emblem on his left leg suddenly shone brightly and instantly became several times larger, as if it contained infinite power.

"Phantom Water Snake Bullet!" Regulus waved his hand, and a green energy ball shot out from his palm, meeting Diablo's Tera Fireball Fist in mid-air.

boom! !

The fireball and the energy ball collided with each other, bursting into dazzling light, and the strong shock wave swept around like a storm, with dust flying and gravel scattering.

When the light faded, Diablo quickly approached Regulus with a teasing smile on his face: "What's wrong? Regulus, is this all you can do?"

Before he finished speaking, dark golden flames suddenly appeared on Diablo's fist, as if to ignite the air.

"Flame Ponton Fist!" Diablo roared, and his fist shot out a hot dark red column of fire, rushing towards Regulus like a fire dragon.

Regulus flashed, kicked his legs, and jumped lightly into the air, avoiding the fatal blow.

"Strong Bull-Breaking Fist!" Regulus shouted in the air, condensing the power of the cosmic beast with one hand. A huge red bull energy emblem condensed in his palm, and then it was fired fiercely at Diablo.

The Red Bull Energy Emblem rushed towards Diablo with unstoppable force like a raging bull. Seeing this, Diablo did not dodge or evade, but crossed his hands in front of his chest, as if he had a plan in mind.

boom! !

The Red Bull Energy Emblem hit Diablo, and a huge explosion instantly erupted, with smoke and dust rising up, covering the sky. However, as the smoke and dust gradually dissipated, Diablo's intact body gradually appeared in front of everyone, with a sneer on his face, as if the attack just now was just a tickle to him.
