Ultra: The copy challenge is very simple?

At this moment, Regulus suddenly felt an inexplicable anxiety in his heart, as if something important had been forgotten in the corner of the world. He looked around, looking at Leo, Astra and Cero, with a trace of regret in his eyes.

Leo noticed that Regulus was abnormal and asked with concern: "What's wrong, Regulus, your expression tells me, what are you worried about?"

Regulus slapped his forehead and shouted, "Oh no! I actually forgot that today is the agreed day!" There was a bit of urgency and self-blame in his voice. It was obvious that this "agreement" was of vital importance to him.

"The agreed date?" Leo, Astra and Cerro all looked puzzled when they heard this. They looked at each other, trying to find the answer in each other's eyes.

Regulus took a deep breath, calmed down his emotions, and explained: "After the battle with the time travelers, Diablo made an agreement with us. After he mastered the Space Monster Fist, he would come to challenge our Space Fantasy Beast Fist to prove that his boxing style is the strongest. And today is the day of that agreement."

At this point, Regulus's face was full of regret: "I actually forgot such an important thing. Now I'm afraid I'm late."

Leo patted Regulus' shoulder and comforted him: "Don't blame yourself too much, Regulus. Now that things have come to this, the only thing we can do is to rush to the agreed location as soon as possible to see if there is still a chance to save the relationship."

Astra also agreed, "Yes, Regulus. No matter what the result is, we must face it bravely. Let's go and find him together."

Zero was excited: "Haha, this is going to be interesting! Diablo must be getting impatient, we have to go give him a surprise!"

"Then let me give you a ride!" Zero said in a firm tone. Before he finished speaking, his body was instantly wrapped in dazzling light, and the shining glorious form suddenly opened, as dazzling as stars.

Then, he waved his hand and tore through the boundaries of space. A huge wormhole in space and time suddenly appeared, like a mysterious passage connecting different worlds.

Regulus and others threw themselves into the gorgeous wormhole without hesitation. Their figures gradually disappeared at the end of the light, starting their new journey.

And on the distant planet D60, a fierce battle is taking place.

Diablo, this powerful being, faced the joint attack of Wang Xiao and Chen Pan, but he seemed unusually calm. His movements were light and precise, and every block and counterattack was just right, as if he was enjoying the fun of this battle.

"Haha, why don't all of you come together? This will save time, and also let me see your true strength!" Diablo's words were full of mockery and disdain, as if he was mocking his opponent's powerlessness.

Stimulated, Wang Xiao and Chen Pan's attacks became more fierce. They each summoned the power of the cosmic beasts, and the air was filled with heat and thunder.

"Red Dragon Flame Fist!" Wang Xiao roared, and a fire dragon emblem burned on his fist, as if it could melt everything; "Electric White Tiger Fist!" Chen Pan used the force of thunder, and the white tiger emblem flashed in the wind of his fist, carrying destructive power.

The shadows of two cosmic mythical beasts appeared in the air, staring at Diablo, their eyes filled with anger and determination for revenge.

It was this arrogant guy who spoke rudely to their cosmic beasts. Now, it is time for him to pay the price for his words and deeds.

The Cosmic Red Dragon and the Cosmic White Tiger, the two mythical beasts each exerted their most powerful strength, and that strength condensed into substantial energy fluctuations around their bodies. Then, these two forces miraculously merged with each other, forming an unprecedented terrifying energy.

Seeing this, Diablo curled up the corner of his mouth into a sneer, that smile was full of contempt and disdain for his opponent's power.

"Come on! Let me show you what real power is!" His words were like ice, piercing the hearts of Wang Xiao and Chen Pan.

At this moment, the two cosmic phantom beasts seemed to feel the determination and anger of their master. Their power reached its peak in an instant, and they merged on their own, turning into a huge energy ball containing the dual power of the red dragon and the white tiger - the Red Dragon and White Tiger Fist.

The energy ball drew a dazzling trajectory in the air and whizzed towards Diablo with the power to destroy the world.

However, facing this attack that was powerful enough to shake the stars, Diablo simply sneered disdainfully: "You dare to show off your petty tricks in front of me?"

Before he finished speaking, a dark golden light began to gather on his fist. It was the concentration of absolute energy in his body. It seemed that even the space was trembling in the face of this power.

Immediately afterwards, Diablo swung his punch with unrivaled power, colliding head-on with the Red Dragon and White Tiger Fist.

boom! !

A deafening explosion resounded through the sky, as if even the stars were trembling.

Under the shocked gazes of Wang Xiao and Chen Pan, Diablo's punch easily shattered the Red Dragon and White Tiger Fist released by the cosmic beasts. The fragments of the energy ball fell like a meteor shower, tearing the surrounding space into pieces.

"too weak!"

Diablo laughed sarcastically, "Is this the so-called strongest boxing technique in the universe, the Cosmic Fantasy Beast Fist? How ridiculous! Now let me show you what a real boxing technique is, and what absolute power is!"

As the words fell, the aura around Diablo surged again, and an even more terrifying force surged in his body, as if it would erupt at any time and completely destroy this world.

Wang Xiao and Chen Pan looked at each other, seeing unprecedented solemnity and sense of crisis in each other's eyes. They knew that the real battle had just begun.

"Space Monster Fist? Tera Fireball Fist!" Diablo roared, and his fists suddenly collided. A ball of dark red energy instantly condensed behind him, gradually transforming into the shadow of the space dinosaur Jetton. The familiar form made Wang Xiao and others gasp involuntarily.

"This is... the Space Dinosaur Jetton!" Chen Pan shouted, his eyes full of disbelief.

Zetton's energy shadow slowly raised his arms and gathered them on his face. A dazzling fireball condensed in his palm, emitting a heart-pounding high temperature. "One trillion degree fireball!" Diablo announced in a cold voice, as if every word contained the power of destruction.

Immediately afterwards, Diablo swung his fists suddenly, accompanied by a roar, and the energy shadow of Jetton also released the one trillion-degree fireball that was enough to melt steel, which cut through the air and went straight towards Wang Xiao and others.

"Red Dragon Flame Fist!" Wang Xiao shouted, and the shadow of the red dragon phantom beast appeared beside him. The power of fire gathered in his fist, and he rushed towards the fireball with blazing flames.

"Electric White Tiger Fist!" Chen Pan was not willing to be outdone, and the White Tiger Phantom Beast followed closely behind. Thunder and lightning intertwined, and together with flames, they formed a defensive barrier.

The two cosmic mythical beasts joined hands again, the power of the Red Dragon and White Tiger Fist doubled, and the light ball that combined fire and lightning collided violently with the fireball in front. A dazzling light burst out in the air, as if two stars exploded in the air.

boom! !

The huge explosion was deafening, and the aftermath of the explosion swept around like a violent storm. Even though Wang Xiao and Chen Pan tried their best to resist, they were still shocked and retreated again and again. They finally managed to steady themselves, gasping for breath, their faces covered with sweat and dust.

"Ahhhh!" the two shouted in unison, feeling both shocked and unwilling.

"What a powerful Space Monster Fist. He can integrate the monsters' skills into the boxing so perfectly. Diablo is such a bold and alternative genius." Wang Xiao couldn't help but comment on Diablo while taking a breath, and his tone was full of awe and recognition.

Even though Diablo has a bad temper and behaves arrogantly, his strength is unquestionable. Wang Xiao has to admit this.

Master Lei Ting witnessed all this from the side, and there was also a flash of surprise in his eyes. "Cosmic Monster Fist... This creative idea of ​​combining the power of monsters with boxing is indeed extraordinary."

"I just used a little bit of my strength, and you guys can't do it?"

“It’s boring!”

"I think you should admit defeat as soon as possible."

After saying that, Diablo suddenly felt a special breath and looked up at the sky.

Suddenly, a huge wormhole in space and time appeared, and then Zero and the others flew out of it.

"Sorry, everyone, I'm late!"

Regulus landed in front of Master Lei Ting and the others.

Seeing this, Diablo snorted coldly: "Are you finally here? Regulus!"
