The genius who counterattacked the mainland

The figures in black robes loomed ever more eerie and terrifying beneath the blood-red sky outside the dark castle. They brought with them numerous helpers, all sorts of bizarre creatures that exuded a sickening aura. Some resembled giant bats, their wings whipping up black whirlwinds; others floated in mid-air like tentacled jellyfish, their tentacles flickering with eerie lightning; and still others resembled skeletal horses, borne from the depths of hell, knights shrouded in black robes atop them, their lances radiating the cold light of death.

Xu Tiancai stared resolutely at the black-robed leader and shouted, "You will never succeed! Even if we die, we will not let you get this box." The Galaxy Key in his hand shone brightly, intertwining with the dark light emanating from the box, creating a strange visual effect. His teammates also stood in full battle formation, each ready with their strongest skills, bracing for the brutal battle that was about to begin.

A shimmering ice bow appeared in Lin's hand, its string gleaming blue, as if forged from icy shards from a frigid land. She drew an arrow from the quiver on her back. The shaft exuded an icy aura, its tip a sharp ice crystal imbued with the power of ice and snow. As she drew the bow and arrow, the temperature around her plummeted, and the moisture in the air quickly condensed into ice crystals, surrounding her.

Agang wielded his great axe, the lightning radiating from it even more violently. Lightning danced across the axe blade, crackling and slamming, as if expressing its fury. His muscles tensed, and he exuded an aura of immense power, like a volcano about to erupt.

The black-robed leader sneered and waved his dark wand, launching the black-robed men and the dark creatures they had brought with them into a combined attack. For a moment, dark energy, sharp whistling sounds, and a pungent odor filled the entire space. Gigantic bats swooped down towards Xu Tiancai and his companions, their maws gaping and belching black sonic waves. Wherever the waves reached, the black rocks on the ground shattered.

Xu Tiancai channeled star power into his feet, dodging the bats' attack with a flash of his body. He swung the Key of the Galaxy, sending an arc of light slicing through the swarm of bats. Like a massive blade, the arc sliced ​​through the bats. Those struck by the arc screamed shrilly, their bodies crumbling to ash in the light. But more bats continued to descend, their speed swift, darting through the sky like black lightning.

Lin released her bowstring, and the icy arrow shot like a meteor at the bats. The icy arrow split in mid-flight, shattering into countless smaller icy arrows, creating a hail of arrows. Upon striking the bats, the small icy arrows quickly froze onto their bodies, transforming them into ice sculptures that then fell from the sky. However, the bats were too numerous, and some managed to break through the defenses and pounce on Lin.

Lin calmly swung her ice bow, and a wall of ice rose before her. The ice was thick and solid, leaving only shallow marks as the bats crashed into it. Agang rushed toward the dark, jellyfish-like creatures, swinging his massive axe with lightning-fast force as he chopped at the jellyfish's tentacles. As the axe blade made contact, the force of lightning coursed through them, sending the jellyfish shuddering in agony.

Suddenly, powerful bolts of lightning erupted from the jellyfish's tentacles, shooting towards A-Gang. A-Gang quickly blocked the attack with his great axe, but the lightning struck, sending him back a few steps. But after stabilizing himself, he charged at the jellyfish again, roaring furiously. The lightning power of his axe intensified, and with a single blow, he split a jellyfish in two.

The black-robed leader saw his men's attacks being repeatedly countered by Xu Tiancai and his men, and he was enraged. He muttered something, and a massive dark vortex appeared at the tip of his dark wand. The dark vortex emanated a powerful suction force, sucking in the surrounding dark energy. The black-robed leader pushed the dark vortex toward Xu Tiancai and his men. Wherever the dark vortex passed, space distorted, sucking everything in.

Xu Tiancai felt the dark vortex's powerful suction and quickly merged the power of the stars with the power of the Galaxy Key, forming an energy shield in front of him. His teammates also moved closer to Xu Tiancai, using the shield's power to resist the suction. However, the dark vortex's suction grew stronger, cracks began to appear in the shield, and Xu Tiancai and his companions were gradually sucked into the vortex.

"Everyone, hold on!" Xu Tiancai shouted. He poured more power into his shield, trying to stabilize the situation. At that moment, he suddenly remembered the power of the box in his hand. He wasn't sure if the box could withstand the dark vortex, but he decided to take a chance. He channeled the box's dark light and shot it towards the dark vortex.

When the dark light from the box came into contact with the dark vortex, a strange reaction occurred between the two. The dark vortex's suction force unexpectedly weakened, and the vortex began to become unstable. Seeing this, the black-robed leader's face changed drastically. He tried to strengthen his control over the dark vortex, but it was no longer under his control and began to backfire.

Xu Tiancai seized this opportunity and led his teammates in a counterattack against the black-robed men. They charged at the enemy like tigers descending from the mountains, their various abilities unleashing a cascade of attacks upon them. Xu Tiancai wielded the Key of the Galaxy, sending a massive lightsaber slashing down at the black-robed leader. The black-robed leader quickly blocked with his dark wand, but the lightsaber and wand collided, emitting a dazzling burst of light. In the blaze, the black-robed leader was knocked back several steps, spitting blood from his mouth.

Elsewhere, Lin and Agang engaged in a fierce battle with the black-robed men and dark creatures. Lin's ice bow continuously fired icy arrows, each one accurately hitting the enemy's vital points. Agang, like a god of war, charged through the enemy, his great axe sending foes falling wherever he touched.

Seeing the situation was dire, the black-robed men began to retreat. But the leader, unwilling to accept defeat, produced a black disc. It was engraved with mysterious runes, which glowed with a dark red light. He tossed the disc into the air, and it rapidly expanded, releasing dark red rays. The dark red light shot towards Xu Tiancai and his men, melting the black rock on the ground wherever it touched.

Xu Tiancai and his companions dodged quickly, but the beams were so fast that some of them were struck. Those struck cried out in pain, their bodies burned by the rays, sustaining severe injuries. Furious, Xu Tiancai unleashed the full power of the Star Power and the Galaxy Key, charging towards the black disc.

As he approached the disc, he wielded the Key of the Galaxy, and a powerful beam of light struck it. The disc trembled violently under the attack, and the runes on it flickered. Seeing this, the black-robed leader quickly unleashed his dark power to stabilize the disc. But Xu Tiancai's attack was too powerful, and a crack appeared on the disc. Then, with a loud bang, the disc exploded.

The shockwave from the disc's explosion spread outward, sending the black-robed men and dark creatures flying. The black-robed leader was once again severely wounded, his body teetering on the brink of collapse. But the madness in his eyes only intensified as he roared to the sky, "Do you think you can defeat us like this? We have even greater power."

After saying this, the black-robed leader pulled a small black bottle from his bosom. The bottle contained a black liquid, and countless souls seemed to be struggling within it. He uncorked the bottle and poured the black liquid onto the ground. Upon contact with the ground, the black liquid quickly spread, then gathered together to form a gigantic black demonic figure.

The black demon's body stood tens of meters tall, its head affixed with massive horns, blazing with black flames. Its eyes resembled two enormous blood-red lanterns, radiating a bloodthirsty glow. Its mouth was filled with sharp fangs, each as tall as a man. Its body was covered in black scales, each etched with sinister runes.

The black demon roared, then lunged at Xu Tiancai and his companions. Every step it took caused the ground to tremble violently, as if the entire world was trembling beneath its feet. Xu Tiancai and his companions felt immense pressure; the power of this black demon far surpassed any enemy they had encountered before.

"Everyone, be careful! This demon is tough!" Xu Tiancai warned. He combined the power of the stars, the power of the Galaxy Key, and the dark light of the box to form a massive energy shield. His teammates also poured their own power into the shield, trying to resist the demon's attacks.

The black demon swung its massive claws and struck the shield. The claws collided with the shield, creating a deafening roar. Huge cracks appeared on the shield, and Xu Tiancai and the others felt a powerful impact, sending their bodies flying backwards.

"We can't just passively take a beating like this. We have to find a way to attack its weaknesses!" Xu Tiancai shouted. He steadied himself in mid-air and charged towards the demon. He tried to find its weakness, but the demon was too large and too powerful. Xu Tiancai's attacks were like a tickle to it.

Lin and Agang also joined in the attack, but their attacks were unable to inflict any substantial damage on the demon. The demon seemed enraged by their attacks, opening its maw and spewing a stream of black flames. The black flames surged towards Xu Tiancai and the others like a torrent, burning everything to ash wherever they touched.

Xu Tiancai and his companions quickly dodged, but the flames were too large and they were still surrounded. At this critical moment, the Galaxy Key in Xu Tiancai's hand suddenly emitted a strange light. Mysterious runes appeared within the light, swirling around Xu Tiancai and his companions, forming a protective circle. The black flames, upon encountering the protective circle, were unable to advance.

"What's going on?" Xu Tiancai looked at the Galaxy Key in surprise. He discovered that after fusing with the Phoenix, the Galaxy Key seemed to have acquired some new abilities. He began to study the runes, trying to find a way to fight the demon.

After some observation, he found that these runes seemed to be related to some kind of energy law of the universe. He tried to adjust his star power and the dark light of the box according to the energy law suggested by the runes, and then merged them together to form a new power.

Xu Tiancai infused the Galaxy Key with new power, causing it to glow even brighter. He swung the Galaxy Key, and a lightsaber imbued with new power shot toward the demon. After the lightsaber struck the demon, a wound appeared on its body. The demon roared in pain, and black smoke billowed from the wound, as if something was being purified.

"Its weakness is inside its body. We need to find a way to attack it!" Xu Tiancai shouted. He led his teammates towards the demon, dodging its attacks and trying to find a way to get inside the demon's body.

During the battle, they discovered that each time the demon attacked, a brief flash of light appeared from its abdomen. They speculated that this might be the core of the demon's power, but also its weakness. Xu Tiancai decided to take a risk and waited for the demon to launch its next attack.

When the demon swung its claws to attack again, Xu Tiancai seized the opportunity and used the power of the stars, the power of the Galaxy Key, and the dark light of the box to the fullest extent, then rushed towards the demon's abdomen. His body passed through the demon's attack like a meteor and flew towards the demon's abdomen.

His teammates also used their skills to shield Xu Tiancai. Lin's ice arrows rained down on the demon's eyes, temporarily blinding it. Agang then attacked the demon's legs with his giant axe, slowing its movements.

Xu Tiancai successfully approached the demon's abdomen. He focused the power of the Galaxy Key at a single point and thrust it towards the glimmering light on the demon's abdomen. When the Galaxy Key made contact with the demon's abdomen, the demon let out a deafening scream. Its body began to tremble violently, and the dark energy surrounding it became chaotic.

But the demon didn't give in. Instead, it attacked even more frantically. It swung its massive tail, sweeping towards Xu Tiancai. Xu Tiancai dodged, but was still struck by the tail, sending him flying like a cannonball. His teammates quickly caught him, and he spat out a mouthful of blood, severely injured.

"We can't give up, keep attacking!" Xu Tiancai said, enduring the pain. They attacked the demon again, and although they were repelled time and time again, they never gave up.

During the fierce battle, they found that the demon's power seemed to be gradually weakening. It turned out that although Xu Tiancai's attack on the demon's abdomen did not completely defeat it, it destroyed its energy core, causing its power to continue to drain.

As the demon's power weakened, their attacks gradually became effective. Lin's ice arrow hit the demon's eye, freezing it and severely affecting its vision. Agang's giant axe chopped the demon's leg, slowing its movements even further.

Xu Tiancai seized the opportunity again and rushed towards the demon. This time, he successfully avoided the demon's attack and reached the demon's abdomen again. He gathered all his strength into the Galaxy Key and struck the wound on the demon's abdomen with all his strength.

With a resounding explosion, the demon's abdomen exploded, and a powerful dark energy gushed out of it. Xu Tiancai and the others quickly dodged as the shockwave from the dark energy explosion leveled everything around them. The black-robed leader and the other black-robed men were also affected, being sent flying and suffering severe injuries.

When the dark energy dissipated, they discovered the demon had vanished, leaving behind only a core radiating a dark glow. The core was engraved with mysterious runes, which shimmered with an eerie light. Xu Tiancai approached the core cautiously, sensing the immense power within, but also the immense danger it held.

"What should we do with this core?" Lin asked.

"We can't let it stay here, or it might cause another disaster," Xu Tiancai said. He attempted to retrieve the core with the Galaxy Key, but when the Galaxy Key touched the core, he saw something strange. It revealed that the core was part of a divine artifact, one that held the power to change the fate of the universe.

"Is this the core of the artifact?" Xu Tiancai said in surprise. He realized the importance of this core. They couldn't let the black-robed man get it, nor could they let it be eroded by the dark forces.

At that moment, the black-robed leader struggled to his feet and lunged at the core. His eyes were filled with greed and madness, wanting to seize the core and use it to fulfill his ambitions. Xu Tiancai quickly used the Galaxy Key to fend off the black-robed leader's attack, and the two of them once again engaged in a fierce struggle.

During the struggle, the core suddenly radiated a light, enveloping both Xu Tiancai and the black-robed leader. They were drawn into a mysterious dimension filled with mystical energies and light. Xu Tiancai and the black-robed leader faced off in the space, with the core between them, emitting an alluring glow. A new battle was about to unfold in this mysterious space, and the fate of the artifact core would determine the future of the universe...
