The genius who counterattacked the mainland

Although the demons were retreating, their roars grew more deafening, their blood-red eyes burning with ever more ferocious flames. They circled in the sky, regrouping, as if preparing to launch an even more frenzied counterattack.

Xu Tiancai tightly grasped the crystal ball, emitting a rainbow of light. Veins bulged on his forehead as he channeled its power with all his might. The crystal ball's light grew increasingly dazzling, like a blazing sun, illuminating everything around it with vibrant colors. The protective shield formed by the light also grew stronger, like an impenetrable fortress.

"We can't give them a chance to breathe. We must repel them completely now!" Xu Tiancai roared, his voice echoing on the battlefield, inspiring everyone.

Agang's muscles bulged, the light from his axe blazing like flames. Like a raging beast, he charged once more at the demon horde. Each swing of his axe stirred a gust of wind, accompanied by a dazzling ray of light as he fiercely slashed at the demons. The demon's scales splattered under the axe, black blood showering like raindrops, but Agang remained unfazed, charging forward bravely.

Lin formed seals with her hands, and elemental power surged around her. She chanted, ancient incantations echoing in the air. Wind transformed into sharp blades, hurling them at the demons like countless flying knives. Fire formed massive fireballs, exploding among the demons, setting off a sea of ​​​​inferno. Water transformed into surging waves, crashing into the demon formation. Earth condensed into massive boulders, hurling them from the sky. Fueled by the power of the crystal ball, these elemental attacks were greatly amplified, sending the demons reeling.

A mysterious figure's black robe fluttered, dark forces swirling around him. He chanted a mystical incantation, and mysterious runes appeared in the darkness. These runes intertwined with the light from the crystal ball, forming a unique power. The runes flew toward the demon like birds, and upon contact, they unleashed a powerful purifying force. Under the influence of this purifying force, the demon's dark forces melted like ice and snow under the scorching sun, struggling painfully.

The Ice Princess waved her wand, causing the surrounding temperature to plummet. At her summons, the massive Ice Giant reappeared, this time even larger and emitting a bone-chilling chill. With heavy steps, the Ice Giant advanced toward the demons, each step causing the ground to tremble. With a sweep of its massive icy arms, it swept the demons away. Those caught in the sweep were instantly frozen into ice sculptures, then shattered into powder by the light of the crystal ball.

The demons, feeling unprecedented pressure, launched a desperate attack. Some spewed black flames from their mouths, surging like surging waves as they swept towards Xu Tiancai and the others. Others, using their massive bodies, crashed into the protective shield like meteorites.

Xu Tiancai raised the artifact high, forming an energy bridge between it and the crystal ball. The crystal ball's light, channeled through the artifact, transformed into a series of multicolored light curtains. These curtains, like layers of sturdy shields, blocked the onslaught of black flames. The demons collided with the protective shield, emitting a deafening roar, but the shield only trembled slightly, remaining intact.

During the fierce battle, Xu Tiancai discovered that the demons seemed to be gathering around a giant demon. This demon was several times larger than the others, its body covered in harder black scales, which shimmered with strange runes. Its eyes were like two giant blood-red suns, emitting a chilling aura.

"That big demon should be their leader. We have to find a way to defeat it first." Xu Tiancai shouted loudly.

The crowd shifted their focus to the demon leader. Agang, brandishing his battle axe, charged at the demon leader. His speed was immense, like a flash of lightning streaking through the air. The battle axe struck the demon leader's scales, sending up a shower of dazzling sparks, but the demon leader merely staggered slightly, sustaining no significant damage. It opened its bloody maw and unleashed a wave of black energy at Agang.

Seeing this, Xu Tiancai hurriedly manipulated the power of the crystal ball, forming an energy shield to block Ah Gang. The energy shield collided with the black energy wave, emitting a deafening explosion. Ah Gang was thrown backward by the impact, but fortunately, the energy shield protected him and he was not injured.

Lin cast a powerful elemental binding spell, attempting to restrain the demon leader's movements. She mobilized the surrounding elemental forces, forming strong chains. These chains entwined the demon leader, tightly binding its limbs. The demon leader struggled, the chains tightening, but the crystal ball's power prevented him from breaking free.

The mysterious figure concentrated his mind, condensing the power of darkness into a massive black sickle. He swung it, striking the demon leader. The sickle struck the leader, leaving a deep wound. Black blood gushed from the wound, but the demon leader roared, and the dark power surged through the wound, causing it to heal.

The Ice Princess cast her ice-sealing magic, lowering the surrounding temperature to an extreme. A thick layer of ice quickly formed on the ground, spreading towards the demon leader. The ice froze the demon leader's lower body, restricting his movement. But the demon leader struggled, and cracks appeared in the ice, threatening to shatter at any moment.

Under the combined attack of the crowd, the demon leader was briefly in dire straits. But as the demon leader, it was extremely powerful and quickly launched a counterattack. The runes on its body flickered with an eerie light, and the surrounding dark forces quickly gathered around it. It struggled hard, breaking the elemental chains and shattering the ice layer on its lower body.

"Everyone be careful, it's going to fight back!" Xu Tiancai warned.

The demon leader spread its massive wings and soared into the air. It muttered something, an ancient, sinister language echoing through the air. As it chanted, the cracks in the sky widened, and more demons poured out. These newly emerged demons varied in size, some with enormous claws, others with long tails. They pounced on Xu Tiancai and his companions, intensifying the battle.

Xu Tiancai and his companions didn't flinch; they continued to battle the demons. Xu Tiancai unleashed the power of his crystal ball to its fullest, unleashing powerful, multicolored arrows. These rained down upon the demons, each one capable of annihilating one.

Agang swung his battle axe again and charged at the demons. He engaged them in close combat, the axe in his hand like a scythe of death, and demons fell wherever it touched. His body was stained with the black blood of the demons, but his eyes remained firm, without a trace of fear.

Lin cast a massive elemental fusion spell, seamlessly blending the power of the crystal ball with the four elements of wind, fire, water, and earth. A massive column of energy rose from her hand, hurtling toward the densest concentration of demons. Wherever the column reached, the demons were completely annihilated, leaving not even a trace of ash.

A mysterious figure summoned the dark power of doom, a force that simultaneously clashed with the light of the crystal ball and merged with it. The dark power of doom, like a massive black storm, swept through the demons. Within the storm, the demons' bodies were gradually disintegrated, their souls purified.

The Ice Princess cast her Ice Extermination spell, transforming everything around her into a world of ice. Massive ice spikes rose from the ground and pierced the demons. Like giant spears, the ice spikes pierced the demons. Frozen on the spikes, their bodies gradually dissipated under the light of the crystal ball.

Under their combined attack, the number of demons gradually decreased, but the demon leader continued to circle in the sky, directing the demons to fight. It seemed to be waiting for an opportunity, a cunning glint in its eyes.

At that moment, Xu Tiancai suddenly sensed a strange vibration coming from the crystal ball. He looked down at it and saw that the light within it was flickering, as if conveying some message to him. He closed his eyes, concentrated, and tried to establish a connection with the crystal ball.

A blurry image appeared in his mind. It depicted an ancient ritual, with figures in ornate robes surrounding a massive crystal ball. This crystal ball was remarkably similar to the one in his hand, only larger and more dazzling. The figures in the image chanted something, seemingly casting a powerful sealing spell. As they chanted, the crystal ball unleashed a tremendous light, sealing the dark forces into an unknown dimension.

"Could this crystal ball be the key to sealing the dark power?" Xu Tiancai guessed in his heart.

He opened his eyes and told everyone what he saw.

"If that's the case, we have to find a way to use the power of the crystal ball to completely seal these demons, especially the demon leader." Lin said.

They began to discuss countermeasures, deciding to try to use the crystal ball's power to perform a sealing spell. Lin, drawing on her knowledge of magic circles and runes, began to draw a massive sealing circle on the ground. A mysterious figure then deployed dark forces around the circle to enhance its stability. Agang and the Ice Princess were tasked with fending off the demon's attacks, buying them time.

Xu Tiancai stood at the center of the magic circle, holding the crystal ball in his hands. He poured his magic power into the crystal ball, attempting to awaken its deeper power. The crystal ball's light grew even brighter, and the surrounding air distorted slightly due to the powerful energy.

As the magic circle gradually completed, the demons seemed to sense danger. The demon leader roared, leading the remaining demons in an even more frenzied attack on Xu Tiancai and the others.

Agang swung his axe, weaving through the demon horde like a whirlwind. Each swing of his axe repelled several demons, but the demons were too numerous, and wounds began to appear on his body. The Ice Princess cast an ice shield magic, forming a solid ice shield around them. However, the demons' attacks were too fierce, and many cracks appeared in the ice shield.

Lin and the mysterious figure sped up, pouring their final ounces of strength into the magic circle. The circle was finally complete, emitting a dazzling light. This light echoed with the light from the crystal ball, forming a massive vortex of energy.

"Everyone, quickly enter the magic circle!" Xu Tiancai shouted.

Everyone ran towards the magic circle. The moment they entered, it released a powerful suction force, sucking the surrounding demons in. The demons struggled in the energy vortex, but could not escape.

The demon leader tried to break free from the energy vortex's suction, but his strength was insignificant compared to the power of the crystal ball and the magic circle. He was slowly sucked towards the center of the magic circle, a look of fear in his eyes.

"Right now, let's cast the sealing magic together!" Xu Tiancai shouted.

They concentrated their minds, merging their powers with the power of the crystal ball and the magic circle. A huge sealing light rose from the magic circle, enveloping the demons. Under the sealing light, the demons' bodies gradually became transparent, and finally disappeared into thin air.

The demon leader roared in pain under the light of the seal. Its body struggled violently, but the light of the seal grew stronger and stronger, and its power gradually weakened.

"You ants, you won't succeed... The power of darkness is endless..." The demon leader roared, but his voice became weaker and weaker.

Finally, the demon leader was completely enveloped by the sealing light, its body transformed into a black light and was sucked into the crystal ball. The crystal ball flickered a few times before returning to calm.

With the demon leader sealed, the cracks in the sky began to heal. Without their leader's command, the remaining demons fell into disarray. Xu Tiancai and his companions seized the opportunity to launch a final attack, wiping out the remaining demons.
