Ultra: The copy challenge is very simple?

Diablo burst into an unbridled laughter that seemed to shake the entire space: "Haha, Regulus, why don't you join in on the feast? This way, our duel will be even more exciting and full of fun!"

As soon as Diablo finished speaking, Regulus' eyes instantly burned with fighting spirit. His fists were clenched and veins bulged, as if every inch of his muscles was telling of his indomitable spirit and anger.

"Diabolo, it's time to draw a limit to the extent to which you look down on others!" Regulus' voice was filled with irrepressible excitement. Obviously, he was deeply touched by the other party's provocation.

At this moment, Wang Xiao keenly sensed the fluctuations in Regulos's heart. He quickly spoke with a stern and caring tone: "Reguluos, you must control your emotions! Don't let the enemy's provocations easily disturb your mind!"

Wang Xiao's words were like a wake-up call, waking Regulus up suddenly. He recalled the hard training he had experienced during this period of time, every sweaty challenge, and every unremitting effort, all for the arrival of this moment.

Thinking of this, Regulus couldn't help but show a trace of shame on his face. He lowered his head, with a hint of self-blame and determination in his voice: "I understand, Teacher Wang Xiao, I will control myself."

Then, Regulus took a deep breath, as if he wanted to absorb all the restlessness and impulse into his chest, and then slowly exhaled. His mood calmed down and his eyes became clear and firm again.

Seeing that Regulus adjusted his condition so quickly, Master Lei Ting and other instructors present cast approving glances at him, their eyes full of trust and expectation.

"Go ahead, Regulus. We believe that you can cooperate well with Brother Leo and the others to face this challenge together."

Regulus felt a warm current in his heart after receiving the encouragement. He nodded vigorously, then flapped his wings and flew high, rushing towards the direction of the Leo brothers and others, ready to join the upcoming battle and prove his growth and transformation with actions.

Just as the fierce battle between the Leo brothers and Diablo was reaching its climax, they skillfully used the force-dissipating technique to resolve Diablo's overwhelming offensive time and time again.

Every time Diablo threw a powerful punch, the Leo brothers cleverly neutralized the force with softness, making it difficult for his attack, although fierce, to hit vital points.

However, Diablo was no ordinary man. He quickly understood the tactics of the Leo brothers. He sneered and his eyes flashed with a cunning light.

"I see. Are you planning to use the force-dissipation technique to drain my energy? Humph, then I want to see how you guys use this force-dissipation technique!"

Before he finished speaking, Diablo raised his fists suddenly. The dark golden energy surrounding him seemed to have condensed all the weight and pressure in the universe. He shouted angrily: "Absolute heavy blow!"

With this roar, a dark golden shock wave rushed out like a wild horse, with a devastating force, and headed straight for the Leo brothers.

The powerful energy fluctuations made the entire space tremble. The Leo brothers looked solemn and were ready to meet this unprecedented challenge.

At this critical moment, a dazzling light suddenly flashed across the sky, and Regulus descended from the sky like a divine soldier, carrying endless power. His eyes were like torches, and he shouted loudly: "Red Dragon White Tiger Fist!"

Following Regulus' call, the shadows of two cosmic mythical beasts, the red dragon and the white tiger, suddenly appeared. They roared and injected their power into Regulus' fist without reservation.

Regulus put his hands together and skillfully combined the two completely different forces - flame and lightning, forming a ball of light with destructive power.

Whoosh-!

This ball of light streaked across the night sky like a meteor, bringing with it blazing flames and blinding lightning, and struck Diablo's absolute heavy blow with the force of thunder.

The two forces collided violently in the air, bursting out with dazzling light and deafening roar, as if even the space was torn apart.

Finally, under the bombardment of Regulus, Diablo's absolute heavy attack was completely broken and turned into nothingness. Seeing this, Diablo's face flashed with surprise, but then he returned to his sneer.

"Are you finally planning to join us? Humph, even if you do, it won't change your eventual defeat!"

After a brief exchange of tacit understanding, Gulos, Leo and Astra charged towards Diablo like three lightning bolts.

Regulus was the first to bear the brunt of the attack. He kicked Diablo fiercely with a "Red Dragon and White Tiger Kick" that combined the power of the red dragon and the white tiger, carrying blazing flames and biting cold wind.

Although Diablo reacted quickly and raised his hand to barely block the attack, Regulus's strength was so strong that he still felt a numbness in his arm.

Immediately afterwards, Leo was not willing to be outdone. He quickly condensed energy in his hands, and several red light bullets poured out like a meteor shower, hitting Diablo's surroundings with a bang. Each explosion was accompanied by the surge of energy, forcing Diablo to retreat again and again.

At this moment, Astra seized the opportunity, jumped up, and kicked Diablo in the chest with great force, kicking him back several steps.

Faced with the combined forces of the three, Diablo's face finally showed a solemn look.

He knew that if he didn't show his true strength, he would be unable to resist the attack of these three people. So, he suddenly spread his arms, and dark golden energy gathered around him, forming an indestructible "absolute defense shield".

"Ultra Triple Flash!" Regulus, Leo and Astra shouted in unison. They clasped their hands together tightly and gathered their strength together. A red lightning-like light burst out from their palms, like a meteor across the sky, and whizzed towards Diablo with unparalleled power.

The power of this beam of light has increased several times compared to the previous "Ultra Double Flash".

Like a sharp sword, it vowed to cut off all obstacles. However, Diablo's "Absolute Defense Shield" was not an ordinary one, and it withstood the initial impact of the light.

But as time went on, cracks began to appear on the dark golden shield. Finally, with a deafening roar, the shield completely collapsed, and the light hit Diablo unhindered.

boom! !

A huge explosion sounded, accompanied by the raging energy and the spread of smoke and dust. Diablo's figure looked extremely embarrassed in the explosion.

When the smoke and dust cleared, one could see that his body was covered with scars. It was obvious that the attack had caused him considerable damage.

Regulus and the other two smiled at each other. They knew that although victory had not yet come, at least they had taken a crucial step.

"Take advantage of now, Leo!" There was unquestionable determination in Regulus' voice, and he quickly handed two gems shining with mysterious light to Leo and Astra.

Leo and Astra took the orb, with a flash of surprise in their eyes: "What is this...?"

"This is the essence of the Cosmic Beast Fist," Regulus explained, "It allows us to unleash the purest and most powerful power of the Cosmic Beast Fist."

"If we can unleash the power of the six cosmic beast fists together, perhaps we can defeat Diablo." Regulus' words were full of expectation and determination.
