The genius who counterattacked the mainland

The Dark Devil's voice resonated through the air like a tangible force of darkness, causing the eardrums of Xu Tiancai and the others to buzz and their very souls to be assaulted. Ah Gang gritted his teeth, resisting the encroaching evil. The eternal fighting spirit within his battle axe burned ever more vigorously, like a never-extinguished golden flame. "No matter what kind of demon you are, today is your end!" he roared, charging towards the Dark Devil.

Xu Tiancai knew the Dark Demon's power was no easy challenge. The moment Gang charged, he continuously channeled his star power into the Colorful Streamer Sword. The blade's multicolored light instantly surged, transforming into a brilliant rainbow that pierced the darkness and slashed towards the Demon. "Gang, beware of his counterattack!" Xu Tiancai shouted.

Lin manipulated the wind element to form a series of rapidly rotating wind shields around Agang, attempting to protect him from the fatal blow from the Dark Demon. The wind shields were like transparent glass, shimmering faintly in the darkness and emitting a whistling sound.

The Dark Devil snorted coldly, raised one black-robed arm, and gently waved it. A wave of black energy surged out like a surging tide, instantly colliding with Agang's battle axe and Xu Tiancai's sword energy. The dark power contained in the energy wave was like an endless abyss, swallowing all light and power that approached. Where the two intersected, space began to distort, erupting with dazzling light and deafening roars. The powerful impact spread like a storm, blowing away large swathes of the surrounding dark clouds.

Ah Gang felt a surge of overwhelming force, sending him flying backward uncontrollably, slamming heavily to the ground. Blood spurted from his mouth. "This demon's power is terrifying!" He wiped the blood from his mouth, his eyes still burning with an unyielding fighting spirit.

Xu Tiancai was also thrown back by the recoil, his blood surging in his chest. However, he forced himself to steady himself, the radiance of the seven-colored sword in his hand not diminishing, but rather becoming even more dazzling. "We can't attack scatteringly. We must work together to find his weakness!" Xu Tiancai shouted, his eyes fixed firmly on the Dark Devil.

Lin flew to Agang's side, and the wind element quickly healed his injuries. At the same time, she said, "The power of this dark demon seems to be endless. It will be difficult for us to win by brute force like this."

At this moment, the Dark Devil slowly rose from his throne. His figure was tall and majestic, and the aura beneath his dark cloak grew stronger. "Do you think you can stand against me? This world will be under my dark rule. You are but ants, struggling in vain." His voice was filled with disdain and arrogance.

In the ancient city, the mysterious figure, the Ice Princess, and the man in white closely watched the battle between Xu Tiancai and his companions through their crystal balls. Seeing their predicament, the mysterious figure rapidly formed hand seals, and the forces of darkness and light fused frantically in his palms, converging into a powerful chaotic energy. "I must go and support them. I can't let them face this dark force alone." With this, he flashed and flew towards the core of the dark cloud.

The Ice Princess and the man in white exchanged glances and nodded. The Ice Princess waved her wand, further strengthening the ancient city's defenses and ensuring the safety of the rear. The man in white played the flute, and the sound transformed into invisible threads of power, connecting the mysterious figure with Xu Tiancai and the others, conveying strength and faith.

As the mysterious figure flew, he continuously absorbed the surrounding elements of darkness and light, his chaotic energy growing ever stronger. He broke through layers of dark clouds and finally reached the battle scene. "I'll lend you a hand!" he shouted, launching a ball of chaotic energy from both hands, smashing it towards the Dark Demon.

The Dark Devil felt the approach of this chaotic energy and turned slightly, a flicker of surprise in his eyes. He waved his black-robed arm again, and a dark barrier appeared before him, blocking the attack of the chaotic energy ball. The chaotic energy ball collided with the dark barrier, triggering an even more violent energy explosion, illuminating the entire dark core area.

Xu Tiancai took the opportunity to shout, "Let's try to use the power of elements to build a sealing formation to trap him!" Everyone nodded and exerted their own strength.

Xu Tiancai transformed the power of the stars into the foundation of the formation, outlining lines of shimmering starlight on the ground. Lin controlled the wind element, blowing along these lines, causing the lines of star power to continuously extend and expand, forming a huge circular outline. The Ice Princess then arrived and waved her wand. Ice magic surged from the tip of her wand, condensing into ice runes on the circular outline, enhancing the stability of the formation. A Gang stood up and injected eternal fighting spirit into the key nodes of the formation, causing the entire formation to emit a golden light. At the center of the formation, a mysterious figure formed a seal with his hands, infusing the chaotic energy into it, harmonizing the power of the various elements.

The Dark Demon watched as everyone constructed the formation and laughed wildly: "You think this small formation can trap me? How naive!" The dark power burst out from his body, like a dark sun, releasing endless dark energy, trying to break through the seal formation that was about to take shape.

The white-robed figure in the distance played a flute that became more rapid, and the sound of the flute transformed into a group of radiant light beasts that pounced on the Dark Demon. The light beasts surrounded the Dark Demon, using their light and power to disrupt his movements, buying time for the completion of the sealing formation.

With everyone's concerted efforts, the sealing formation finally took shape. A massive, multicolored light rose from the ground, enveloping the Dark Demon. The various elemental forces within the formation intertwined, forming chains that entwined the Dark Demon.

Trapped within the formation, the Dark Demon roared angrily and struggled. His dark power collided with the power of the sealing formation, triggering wave after wave of energy shockwaves. The light of the formation flickered, sometimes brighter, sometimes more, as if the Dark Demon could break through at any moment.

"We must reinforce the formation as soon as possible and not let him escape!" Xu Tiancai shouted. Everyone increased their strength output. Their foreheads were covered with sweat and their faces turned pale due to excessive exertion.

However, the Dark Demon's power was too great, and as he struggled, cracks began to appear in the seal. "This won't work. We need a more powerful source of power!" the Ice Princess said anxiously.

Just as everyone was feeling hopeless, Xu Tiancai suddenly remembered the Earth Elemental Heart. He pulled it from his bosom and sensed the immense power within. "Perhaps the Earth Elemental Heart can help us!" he exclaimed, slowly placing it into the core of the sealing formation.

After the Earth Elemental Heart entered the formation, it instantly released a powerful earth elemental force. This force, like the pulse of the earth, was steady and profound, quickly merging with the various elemental forces within the sealing formation. Blessed by the earth elemental power, the sealing formation glowed brightly, and the cracks began to gradually heal.

The Dark Demon felt the power of the Earth Elemental Heart and began to struggle even more frantically. His dark power, like a black tornado, raged through the formation, engaging in a thrilling battle with the sealing force.

"Everyone hold on! We can't let him succeed!" Xu Tiancai shouted loudly. Everyone gritted their teeth and concentrated their magic power, fighting spirit and mental strength to the limit to maintain the operation of the sealing formation.

In this fierce battle, time seemed to stretch endlessly. Every second was accompanied by the collision and impact of energy. The entire dark core area trembled, as if it would collapse at any moment.

Suddenly, the Dark Devil let out an earth-shattering roar. His body began to swell, and dark power erupted like a volcanic eruption. Under the impact of this powerful force, huge cracks appeared in the seal formation again, and it seemed that it was about to collapse completely.

"Is it really impossible for us to stop him?" A trace of despair flashed in Lin's eyes.

At this critical moment, a dazzling golden light suddenly descended from the sky. Contained within this light was a sacred and powerful force, like a sharp blade, it pierced through the dark clouds and shot towards the dark demon trapped in the sealing formation.

The Dark Demon was struck by this golden light, and his body shook violently. His expanding body stopped instantly, and the dark power also stagnated. "What kind of power is this?" he cried in horror.

Everyone looked up and saw an angel radiating golden light appear in the sky. The angel had a holy face, huge white wings sprouted from its back, and in its hand, a long sword gleaming with divine light. "Evil being, your end has come!" The angel's voice was clear and majestic, echoing throughout the space.

It turned out that this was the guardian of the world, the Light Messenger, who had sensed the threat posed by the Dark Devil and had come to his aid. Upon his arrival, the Light Messenger swung his sacred sword, sending streams of golden energy slashing at the Dark Devil. Wherever the sword energy reached, the dark forces dissipated as quickly as ice and snow meeting the blazing sun.

Xu Tiancai and the others saw the appearance of the Light Messenger, and hope was rekindled in their hearts. They took the opportunity to increase their power output, coordinating with the Light Messenger's attack to further suppress the Dark Devil.

Under the combined attack of the Light Envoy, Xu Tiancai, and the others, the Dark Devil gradually lost ground. His dark power steadily weakened, and his body began to become ethereal. "No! I won't give up!" He roared one last time, but was ultimately completely sealed by the sealing formation.

With the Dark Demon sealed, the dark clouds began to dissipate rapidly, and sunlight once again shone across the desert. The world crisis was temporarily resolved. Xu Tiancai and the others sat exhausted on the ground, their faces brimming with smiles of triumph.

The Messenger of Light slowly landed in front of them, smiled and said, "You have done a good job and saved the world. But the power of darkness will never completely disappear. You must always be vigilant and protect this hard-won light." After that, the Messenger of Light turned into a golden light and disappeared into the sky.

Xu Tiancai and the others gazed at the sky, knowing that their mission was far from over. In the future, they would continue to explore this mysterious world, safeguarding its peace and tranquility while facing even more unknown challenges...
