The genius who counterattacked the mainland

Black energy tentacles surged like a raging black tide, sweeping towards Xu Tiancai and the others in wave after wave. Though the vines Lin summoned were covered in thorns, the tentacles were incredibly resilient. Some broke free from the vines, while others crushed them and continued their assault.

Agang steadied himself, his golden armor gleaming brightly. Runes flickered, as if flowing with ancient power. With a roar, he swung his axe again, blazing with flames, this time with even greater force than before. Wherever the axe passed, the air ripped apart, emitting a sharp whistling sound. Several tentacles were severed by the powerful force, and black liquid splattered, spilling onto the ground and emitting plumes of black smoke.

The mysterious figure's black robe fluttered, his cape rustling. He quickly formed seals with his hands, gathering dark energy in his palms, transforming into countless black flying needles that shot towards the densely populated area of ​​tentacles. Each needle possessed powerful penetrating power, instantly creating countless small holes in the tentacles struck, allowing black energy to leak out, slowing the tentacles' attacks.

The Ice Princess waved her wand, and the connection between her green boots and the earth grew stronger. She channeled the power of ice through her boots and into the ground. Instantly, a vast expanse of ice spread out from her. Sharp icy spikes quickly sprouted from the ice, blocking the tentacles that attacked her, some even being pierced directly, leaving them unable to move.

Xu Tiancai's eyes were solemn. The silver sword in his hand resonated with the divine artifact, emitting a dazzling multicolored light. His figure flashed, moving like a ghost among the tentacles, and his sword swung out arcs of silver light. Each arc of light precisely slashed at the tentacles, severing those that approached his companions.

However, the black sphere seemed to sense their resistance and began to unleash even more powerful energy. A black light erupted from the center of the sphere, shaking the entire dark space. As the light intensified, more and thicker tentacles emerged from the sphere. These newly emerged tentacles were not only more powerful, but also covered in a layer of black scales, greatly enhancing their defensive capabilities.

"Everyone, be careful! This thing's getting tougher!" Xu Tiancai shouted. He concentrated, attempting to further merge the power of the artifact and the longsword. A mysterious force surged from the depths of his soul, flowing down his arm and into the longsword. The longsword's light grew even brighter, and mysterious runes appeared around the blade. These runes resonated with the runes on the artifact, forming a unique force field.

Lin took a deep breath, knowing she would need to summon even more powerful elemental magic to confront the imminent crisis. She closed her eyes, immersing her mind completely in the elemental world. Wind elements gathered frantically, forming a massive tornado. Fire elements ignited at the tornado's center, tinting it a fiery crimson. Water elements condensed from the void, transforming into a torrential downpour of water arrows that merged with the tornado. Earth elements formed a solid rock base at the tornado's base. The blue light imbued by her helmet, like a baton, seamlessly integrated these elemental powers. "Elemental Fury!" Lin cried out, and a massive elemental tornado swept toward the black sphere, crushing the black tentacles wherever it passed, stripping away the black scales caught in its grip with its powerful force.

Agang sensed Lin's powerful magic, his fighting spirit soaring even higher. He channeled all his strength into his battle axe, and the flames on it burned even more fiercely, gradually changing from red to a deep blue-white, a sign of the flames reaching extreme heat. "Flames Slash the Sky!" Agang roared, leaping high and swinging his battle axe toward the black sphere. A massive blue-white flaming slash flew from the battle axe, streaking through the dark space like a flaming meteor, echoing with the elemental tornado and attacking the black sphere.

A flicker of determination flashed in the mysterious figure's eyes, knowing he now had to give it his all. He elevated his fusion with the dark forces to a new level, his body beneath his black robe seeming to merge with the darkness. He chanted, an ancient incantation echoing through the dark space. As he chanted, the surrounding dark forces began to surge violently, transforming into a massive black phoenix. Its eyes flashed an eerie red, and it spread its wings, letting out a resounding cry, as it charged toward the black sphere. Each feather seemed composed of the purest dark force. As it flew, the black phoenix continuously absorbed the surrounding dark energy, growing ever larger and more imposing.

Not to be outdone, the Ice Princess planted her wand in the ground, raised her hands high, and chanted an ice spell. As the spell rang out, the surrounding temperature plummeted, and ice crystals began to form throughout the dark space. These crystals quickly coalesced, forming a massive ice giant. The ice giant stood tens of meters tall, its body translucent and crystalline, each muscle seemingly composed of the hardest ice. The ice giant took heavy steps, each leaving deep footprints on the ground. It stalked toward the black sphere, easily crushing the black tentacles in its path. Those that came too close were frozen by the extreme cold emanating from its body.

The black sphere felt the powerful attack from everyone, and swirling runes began to appear on its surface. These runes exuded a sinister aura, colliding with the force of the attack. As the Elemental Tornado, Flame Slash, Dark Phoenix, and Ice Giant approached the black sphere, they produced a violent energy reaction with the runes.

The moment the tip of the elemental tornado touched the rune, the wind element was twisted by the rune's power, and the originally orderly rotation became chaotic. But Lin gritted her teeth and concentrated on maintaining the elemental balance. The fire element burned even more fiercely in the chaos, constantly attacking the rune's defense.

Agang's flame slash collided with the rune, and the blue-white flames intertwined with the black light of the rune. The power of the flame slash was weakened slightly by the rune, but Agang's strength continued to flow into it. The runes on the battle axe and the runes on the armor echoed with each other, providing continuous power for the flame slash.

As the mysterious figure's Dark Phoenix approached the rune, it was eroded by the evil power emanating from it. Black spots began to appear on the phoenix's feathers, but the mysterious figure promptly adjusted the output of the dark power, strengthening its control over the phoenix. The Dark Phoenix let out an angry cry and attacked the rune with its sharp beak and razor-sharp claws, attempting to break through the defenses.

The Ice Giant walked up to the black sphere and smashed its massive fist against the rune. The moment its fist made contact with the rune, a powerful recoil was felt, cracking the Ice Giant's arm. But the Ice Princess didn't flinch. She injected even more icy power into the giant, and the Ice Giant swung his fist again, this time even more powerfully, cracking the rune slightly under the powerful impact.

Xu Tiancai seized the opportunity and, with lightning speed, rushed towards the black sphere. As he approached the sphere, he unleashed the full power of his artifact and sword. Multicolored light and silver arcs intertwined, forming a powerful attack wave. When his attack wave collided with the already cracked runes on the sphere, the runes finally couldn't withstand the pressure and shattered completely.

The black sphere trembled violently under attack. Cracks appeared on its surface, and black energy leaked out. The tentacles that had been attacking frantically became chaotic and disorderly, and some began to retract into the sphere.

"We can't give it a chance to breathe!" Xu Tiancai shouted. He continued to charge toward the sphere, stabbing his sword at the cracks in it. The other four followed suit, launching a new round of attacks.

Lin controlled the elemental tornado, sweeping toward the cracks in the sphere. The powerful elemental force attempted to penetrate the sphere's interior through the cracks, destroying the core. Agang swung his battle axe again, slashing at the cracks in the sphere. The flames on the axe attempted to consume the dark energy within. A mysterious figure directed the Dark Phoenix to attack the cracks in the sphere with its beak and claws, attempting to widen the cracks and expose the dark power within. The Ice Princess instructed the Ice Giant to repeatedly smash his fists into the cracks in the sphere, the immense impact causing the cracks to widen further.

Under their combined attack, the cracks in the sphere widened, and black energy poured out like a flood. This energy was highly corrosive, and upon contact with the bodies of the people, they felt a sharp pain. But they did not retreat, and continued to attack.

Suddenly, a powerful roar erupted from the black sphere, as if from some ancient, evil creature. As the roar rang out, the sphere shattered completely, and an extremely powerful dark force erupted from it. This dark force transformed into a gigantic black demon with enormous wings, sharp claws, and eyes burning with black flames.

"You ants, how dare you disturb my sleep? You will all become my sacrifices!" The black devil's voice echoed in the dark space like thunder. It waved its huge claws and pounced on everyone.

Xu Tiancai bore the brunt of the attack. He raised his longsword, and the power of the artifact and the longsword merged to form a colorful light curtain, trying to resist the demon's attack. The demon's claws grasped the colorful light curtain, and the light curtain trembled violently. Xu Tiancai felt as if he was bearing the weight of a mountain. His legs buckled involuntarily, but he still gritted his teeth and persevered.

Seeing this, Agang rushed forward and slashed at the demon's claws with his battle axe. The axe and claws collided, sending up a shower of black sparks. His armor shone brightly under the powerful impact, partially blocking the force, but Agang was still thrown backward and fell heavily to the ground.

Lin cast elemental magic, attempting to bind the demon with its power. She summoned massive vines, entwined with lightning, which wound toward the demon. Simultaneously, she summoned fire, waterspouts, and boulders to attack the demon from various directions. But the demon simply flapped its wings, scattering the vines and shattering the fire, waterspouts, and boulders.

The mysterious figure and the Ice Princess also launched their attacks simultaneously. The mysterious figure transformed the power of darkness into black chains, attempting to restrain the demon's movements. The Ice Princess commanded the Ice Giant to charge at the demon, and the giant's fist smashed into the demon with tremendous force. However, the demon's power was too great, and the black chains broke free the moment they made contact with the demon, and the Ice Giant's fist was easily deflected by the demon.

"Let's attack together! We can't let it succeed!" Xu Tiancai shouted. He raised his sword again, the artifact's light becoming even brighter. He poured his soul power into the sword, and the runes on it shone with a mysterious light. He rushed towards the demon, this time faster and with greater force.

The other four also regained their spirits. They gathered together and launched their most powerful attack on the demon. Agang's battle axe burned with blue-white flames, and he charged at the demon with a roar. Lin combined all the elemental forces to form a huge energy ball and threw it at the demon. The mysterious figure increased his dark power to the extreme, transforming into a black lightning and attacking the demon. The Ice Princess unleashed the Ice Giant's maximum power, and the giant's body emitted a dazzling blue light as it rushed towards the demon.

Under the combined attack of everyone, the demon was temporarily subdued. Its body was struck by energy balls, burned by blue-white flames, struck by black lightning, and smashed by the ice giant's fist. But the demon was not defeated. It roared angrily, and the dark power within it erupted once more.

"Your attacks are too weak. Now it's my turn!" the demon roared. It opened its massive mouth and spewed out a stream of black flames. The black flames swept towards everyone like a surging ocean wave, distorting space wherever the flames touched.

Xu Tiancai and the others scrambled to avoid the flames, but the black flames were incredibly fast and widespread. Agang shielded himself with his armor, but the intense heat still caused him a sharp pain. Lin cast an elemental shield, but the black flames were too powerful, and the shield began to crack under the impact. The mysterious figure used the spatial ability of his cloak to avoid the flames, but some of the flames still burned his black robe. The Ice Princess placed an ice giant in front of her, but the giant began to melt under the burning black flames.
