The genius who counterattacked the mainland

The power of darkness surged from the horizon like a surging tide, shrouding the sky as if enveloped by a vast black curtain, completely absorbing the once bright light. Wherever the dark force passed, flowers, plants, and trees rapidly withered, and the once vibrant earth instantly became gray and dull, as if life had been instantly drained away.

Xu Tiancai and the others sensed this powerful threat and concentrated their energy on maintaining the fusion of the Heart of Element and the Heart of Light crystal. The multicolored light emanating from the Heart of Light crystal flickered under the encroaching darkness, like a candle in the wind, but they showed no sign of retreating.

"We can't let this dark force destroy our plan. We must hold on!" Xu Tiancai shouted loudly, his eyes revealing firm determination. He held the sword tightly in his hand, and the power of light flickered violently on the sword, like a ray of hope in the darkness.

Agang plunged his battle axe into the ground, his feet firmly planted, like an unshakable iron tower. His muscles tensed, and he continuously poured his own strength into the energy field surrounding the Elemental Heart. He roared, "Come on, dark forces! I won't let you succeed!" The flames on the battle axe burned even more fiercely in the darkness, resonating with the power of light, forming a line of defense against darkness.

Lin's forehead was covered in beads of sweat. Her hands danced rapidly, casting elemental magic, attempting to stabilize the fusion of the Elemental Heart and the forces of light. Wind elements whistled around, forming barriers to block the approach of the forces of darkness. Fire elements burned around the energy field, strengthening the power of light. Water elements transformed into wisps of cool vapor, nourishing the weary bodies and minds of the crowd and infusing the energy field with a gentle power. Earth elements condensed beneath her feet, further solidifying their foundation. Her eyes were focused and determined, and she chanted a mantra, waging an invisible battle against the forces of darkness.

The mysterious figure's black robe rustled as he waved his hands, skillfully blending the forces of darkness and light, transforming them into interwoven black and golden rays. These rays darted around the energy field, patching the holes left by the darkness's encroachment. His gaze, like a torch, pierced the darkness, ever vigilant of the dark forces' movements. He loudly warned everyone, "Everyone, be careful! This dark force is even more powerful than we imagined. It seems to be searching for our weaknesses!"

The Ice Princess waved her wand, and icy power spread from her feet, forming a thick layer of ice around them. The ice shimmered with a shimmering light, reflecting the power of light and enhancing their defenses. She continuously poured her own magic into the ice, solidifying it, chanting ancient ice spells, attempting to harness the purity of ice power to resist the encroachment of darkness.

The man in white played his flute faster and faster, the notes growing rapid and passionate. Notes flew from the flute, transforming into birds of light and elemental spirits of various shapes. The birds of light shone brightly in the darkness, darting like meteors, attacking the approaching forces of darkness. The elemental spirits surrounded the energy field, coordinating with the other elemental forces to form a multi-layered defense system. The man in white's expression grew solemn. He knew that this battle depended on the fate of the world; he could not afford to slack off.

The forces of darkness continuously assaulted everyone's defenses, wave after wave of black waves reaching out like demonic tentacles. Each impact caused everyone's defenses to tremble, as if they would completely collapse in the next second. Under the impact of the dark forces, some dark creatures began to appear, weaving through the dark waves, trying to break through the defenses.

These dark creatures have various shapes. Some are shaped like giant bats, with wingspans of tens of meters. Their wings are covered with sharp bone spurs, and every flap of their wings brings up a black whirlwind; some are as illusory as ghosts, with transparent bodies but emitting a strong dark aura. They can easily pass through objects and float towards the weak points of the energy field; others are like huge monsters condensed from dark forces, with huge bodies and black flames spewing from their mouths. Every step they take causes the earth to tremble violently.

A massive bat charged at the defenses, its sharp bone spikes easily piercing the wind elemental's barrier. The wind elemental whistled sharply as the spikes pierced it, as if groaning in pain. Seeing this, Agang swung his battle axe and struck the bat. The flames on the axe intertwined with the power of light, slicing a brilliant arc through the darkness. The axe struck the bat's wing, splashing a black liquid. The bat let out a piercing cry, and the flames of light ignited on its slashed wing. But the bat didn't retreat, instead charging at Agang with even greater frenzy.

Ghostly dark creatures passed through the earth elemental's defenses and drifted toward the energy field. Their bodies resembled puffs of cold black smoke, causing the surrounding temperature to plummet wherever they passed. Lin cast water magic, transforming the water into sharp icicles and shooting them toward the ghosts. The icicles pierced the ghost's body with a sizzling sound. The ghost's body trembled slightly under the attack of the icicles, but quickly recovered and continued to drift toward the energy field. A mysterious figure flashed and appeared in front of the ghost. He waved his hands, and a light composed of the intertwined forces of darkness and light wrapped around the ghost like a spirit snake. The ghost struggled within the light's constraints, emitting a series of shrill cries.

The massive monster unleashed black flames, blazing towards the ice, which quickly melted under the intense heat. The Ice Princess frowned, waving her wand, increasing the power of her ice. More ice formed in front of the flames, attempting to block their spread. However, the intense heat of the black flames consumed the Ice Princess's magical energy as the ice melted and regenerated, draining her immensely. The figure in white played a flute, summoning more water elementals. These, combined with the Ice Princess's icy power, formed a thicker defensive layer of ice, temporarily repelling the black flames.

As the crowd battled the dark creatures, the main force of darkness continued to assault the energy field surrounding the Heart of Light Crystal. Waves of darkness followed one after another, each more powerful than the last. Under the relentless onslaught of the dark forces, cracks began to appear in the energy field, and multicolored light leaked from the cracks, making the situation extremely critical.

"We need more power! We can't let the darkness break through our defenses!" Xu Tiancai shouted. He channeled the power of the Heart of Light Crystal towards the cracks, attempting to repair the defenses. But the darkness was too powerful, and his strength was only a drop in the bucket.

Just as everyone was feeling hopeless, a powerful wave of energy suddenly emanated from afar. This wave of energy carried a sacred and pure aura, like the light of dawn, piercing the darkness and surging towards them. A glimmer of hope ignited in the hearts of the people. They didn't know where this power came from, but they could sense that it was a force in their favor.

As the energy wave approached, the crowd saw a group of knights clad in golden armor. These knights rode white steeds, their hooves seemingly treading light as they galloped. The knights wielded spears that shone with divine light, and their armor was engraved with mysterious runes that radiated powerful power under the light.

"It's the Knights of Light!" the man in white shouted in surprise, and his flute became more passionate, as if echoing the arrival of the Knights of Light.

The Knights of Light surged into the darkness like a golden torrent. Their spears swung, each thrust piercing the dark creatures and dispelling the dark forces. Golden light shone in the darkness, combining with the collective defensive power to temporarily repel the dark forces' attacks.

The leader of the Knights of Light was a knight with a stern face. He approached Xu Tiancai and the others and said loudly, "We sense the dark forces here and your battle, and have come to support you. Together we must fight this darkness and protect the light of the world."

Xu Tiancai said gratefully, "Thank you for coming. Now we must quickly repair the energy field and destroy the fragments of the dark crystal ball. We must not let the Lord of Darkness succeed in his plot."

With the help of the Knights of Light, the pressure on everyone was greatly reduced. They began to focus on repairing the cracks in the energy field. Xu Tiancai infused his sword with the power of light and slashed it across the cracks, the power of light mending them like a thread. Agang, Lin, the mysterious figure, the Ice Princess, and the man in white also used their powers to help repair the energy field. The Knights of Light stood guard, fending off the attacks of the dark creatures.

After some effort, the cracks in the energy field were finally repaired, and the colorful light stabilized again. But the dark force did not give up, and began to gather more dark creatures, preparing to launch an even more powerful attack.

A massive black vortex emerged from the center of the dark forces, and from it continuously emerged various dark creatures. These dark creatures were more numerous than before, and even more powerful. They rushed towards the crowd and the Knights of Light, and the battle once again entered a white-hot stage.

The Knights of Light divided into several teams, each engaged in attacking the dark creatures from different directions. Their spears swung with impenetrable force, each strike accurately hitting their target. But the dark creatures' attacks grew increasingly ferocious, and some knights began to suffer injuries. Black streaks appeared on their armor, signs of corrosion from the dark forces.

Xu Tiancai and the others rejoined the battle. A-Gang, brandishing his battle axe, engaged in a fierce battle with a massive dark monster. Sparks flew as the axe collided with the monster's claws. A-Gang's strength reached its peak in the battle, emanating a powerful aura, each attack laced with determination to win.

Lin cast elemental magic, merging all the elemental forces into a massive, multicolored sphere. She flung it toward the densest concentration of dark creatures, and it exploded amidst the swarm. A powerful wave of energy instantly scatters the surrounding dark creatures. However, the sphere's energy consumption was immense, and Lin's face paled as her magic power was nearly depleted.

A mysterious figure weaved among the dark creatures, his form as elusive as a ghost. He used his cloak's spatial ability to search for the dark creatures' leader. After searching for a while, he discovered a massive ghost hidden within a dark vortex. This ghost exuded an extremely powerful dark aura, seemingly commanding all the dark creatures. The mysterious figure charged at the ghost, the forces of darkness and light intertwined in his hands, ready to deliver a fatal blow.

The Ice Princess waved her wand, and the power of ice merged with the power of light, forming a vast ice castle of light. Its walls, composed of impervious, bright ice, shone with dazzling light. From the castle's spires, countless ice-light arrows rained down upon the creatures of darkness. Each arrow imbued with a powerful purifying force, freezing the dark creatures wherever it struck, before gradually dissipating under the radiance of light. But the Ice Princess's magic power was rapidly depleting, and her body began to tremble.

The man in white played his flute, the sound transforming into powerful waves of energy that swept towards the dark creatures. Wherever the waves reached, the dark creatures were shattered. Simultaneously, he summoned more elemental spirits and birds of light to aid the Knights of Light in their battle. But the constant playing stretched the man's stamina to its limit. Veins popped on his forehead, and sweat poured down his face.

Through the combined efforts of the people and the Knights of Light, the dark creatures' attacks were repelled once again. But they also paid a heavy price, with many Knights of Light injured and their strength exhausted. However, they knew they couldn't give up now and had to persevere to the end.

At this point, the dark force seemed to sense the fatigue of the crowd and launched another attack. The black vortex grew larger, and from it emerged an even larger dark creature. This dark creature resembled a giant octopus, with numerous tentacles, each covered in sharp suckers and bone spurs. Its body exuded a rich dark aura, as if it were the embodiment of the power of darkness.

A giant octopus swam toward the energy field, its tentacles capable of destroying everything around it with a single wave. The Knights of the Order of Light rushed toward the octopus, but their attacks were ineffective against it. The octopus's tentacles easily flung the knights away, and some were even entangled, plunging them into danger.

Seeing this, Xu Tiancai and the others cheered up again. They knew that this was the final crucial battle, and they had to defeat the giant octopus to complete the fusion of the Elemental Heart and the Power of Light and destroy the fragments of the Dark Crystal Ball.

Xu Tiancai, sword and artifact in hand, charged at the octopus. He fused the power of light with the other elemental forces, infusing it into his sword. The sword shone brightly, and he thrust it at one of the octopus's tentacles. The sword pierced the tentacle, sending a splash of black liquid. However, the tentacle remained intact, instead tightly sucking Xu Tiancai's sword. Xu Tiancai pulled hard, but could not break free.

Agang swung his battle axe, slashing at the octopus's other tentacle. There was a loud thud as the axe struck the tentacle, but it only trembled slightly. Agang's attack was easily deflected by the octopus, and the recoil from the octopus's tentacle sent him back a few steps.

Lin cast a spell, attempting to disrupt the octopus's movements with elemental power. She summoned a powerful wind element, creating a massive tornado that swept toward the octopus. The tornado entangled several of the octopus's tentacles, slowing its movements. However, the octopus quickly broke free and continued its advance toward the energy field.

The mysterious figure used his cloak's spatial ability to ascend above the octopus. With a wave of his hands, he combined the forces of darkness and light into a massive sword of light and darkness, thrusting it towards the octopus's head. The sword pierced the octopus's head, and the octopus roared in pain, but it was not seriously injured. Instead, it lashed out at the mysterious figure with one of its tentacle. The mysterious figure quickly dodged, narrowly avoiding the octopus's attack.

The Ice Princess waved her wand, and the power of ice formed a thick layer of ice around the octopus. The ice quickly spread, freezing part of the octopus's body. But the octopus was so strong that it struggled hard, cracking the ice and shattering it.

The man in white played a flute, and the sound transformed into a giant bird of light, which flew towards the octopus's eye. Its beak was incredibly sharp, and it pecked at the octopus's eye. The octopus sensed danger and shielded its eye with one of its tentacle. The bird's beak struck the tentacle, sending sparks flying but causing no real damage.

As everyone was locked in a bitter struggle, the leader of the Knights of Light made a decision. He led the remaining knights and charged towards the octopus. They pooled their strength, forming a massive golden column of energy. At the cost of their own lives, the knights launched a final attack on the octopus.

The golden energy column rushed towards the octopus. The octopus tried to dodge, but the energy column was too fast and hit the octopus directly. The octopus let out a shrill scream. A huge wound appeared on its body under the attack of the golden energy column, and black liquid gushed out of the wound.

Seizing this opportunity, Xu Tiancai and his companions launched another attack. They gathered all their strength and attacked the octopus's wound. With their concerted efforts, the octopus was finally completely destroyed.

With the octopus's death, the dark forces began to dissipate. But the people did not let down their guard. They knew that the Lord of Darkness would not give up easily, and this was just part of his conspiracy. They continued to maintain the fusion of the Elemental Heart and the power of light, preparing to destroy the fragments of the dark crystal ball.

At this moment, a sinister laugh echoed from the sky. "Do you think you can stop me like this? How naive!" The Lord of Darkness's voice echoed in the sky, mocking everyone.

Suddenly, a black lightning bolt struck down from the sky, heading towards the energy field. This black lightning bolt contained extremely powerful dark power, and its goal was to destroy the Heart of Elements and the Heart of Light crystals, thus preventing everyone from making plans.

Everyone hurriedly strengthened their defenses, preparing for this final challenge. Xu Tiancai boosted his light power to its fullest. He stood at the front of the energy field, like a beacon of light, ready to use his body to block the black lightning. Agang, Lin, the mysterious figure, the Ice Princess, and the man in white also poured their remaining strength into the defense. They knew this was a crucial moment that would determine the fate of the world, and they could not retreat.

The black lightning is getting closer and closer, and the oppressive feeling it brings makes everyone almost unable to breathe. In this critical moment, can they withstand the black lightning and successfully destroy the fragments of the dark crystal ball? What will be the fate of the world?
