The genius who counterattacked the mainland

"Attack the scale of different color on its abdomen!" Xu Tiancai shouted, his voice still clearly audible amid the black flames and roars spewed out by the Dark Demon.

Everyone sprang into action. Lin cast a wind-based acceleration spell, instantly increasing everyone's speed. Agang charged at the Dark Demon like a cannonball, his battle axe swirling with the immense power bestowed by the artifact, sending a whistling gust of wind. The mysterious figure and the Ice Princess flanked him, each unleashing their most powerful spells. The mysterious figure summoned the armor-piercing power of darkness, transforming it into a series of black spikes that shot towards the Dark Demon's abdomen. The Ice Princess, in turn, unleashed ice magic, rapidly condensing the surrounding water vapor into massive cones of ice that rained down upon the target.

Xu Tiancai perfectly fused the power of the stars, the phoenix, the guardian pearl, and the four divine artifacts. A lightsaber, gleaming with brilliant light, appeared in his hand. He leaped high and thrust it fiercely at the Dark Devil's abdomen. Wherever the lightsaber passed, space was torn apart, leaving tiny cracks.

The Dark Devil seemed to sense their intentions. With a sweep of its massive hand, it sent a wave of black energy careening towards them. Wherever the wave reached, the magma on the ground was stirred up, transforming into blazing pillars of fire that rushed towards them.

Agang bore the brunt of the attack, wielding his battle axe and splitting the approaching pillars of fire one by one. The scorching lava splashed upon him, but thanks to his tenacious will and the protection of his artifact, he sustained no significant damage. Lin quickly cast a water shield, enveloping everyone. The shield sizzled as it made contact with the lava, sending a large amount of steam rising.

The mysterious figure and the Ice Princess' magical attacks collided with the Dark Demon's energy wave, emitting a dazzling light. The dark armor-piercing spikes were partially dispersed by the energy wave, but some still broke through the defenses and shot towards the Dark Demon's abdomen. Many ice cones were shattered by the energy wave, but the remaining ones continued to fly towards their target.

While dodging the pillars of fire, Xu Tiancai seized the opportunity, slipped through the gaps in the energy waves, and continued his charge towards the Dark Devil's abdomen. His lightsaber finally pierced the scales of different colors. The moment the lightsaber and scales made contact, a powerful energy surge erupted. The Dark Devil roared in agony, and the entire hall trembled violently at the roar.

"Our attack is effective, let's continue attacking its abdomen!" Xu Tiancai shouted. The lightsaber in his hand shone brighter and stabbed the scales hard, trying to destroy it.

Agang, Lin, the mysterious figure, and the Ice Princess also increased their attack power, launching even more fierce attacks on the Dark Demon's abdomen. Every time Agang's battle axe struck the Dark Demon's body, a burst of black sparks would fly; Lin's magic continuously struck the Dark Demon's abdomen, trying to weaken its defenses; the attacks of the mysterious figure and the Ice Princess also hit the target accurately, causing considerable damage to the Dark Demon.

The Dark Devil was enraged. He swung his massive fist and smashed down on them. The fist came down like a mountain, bearing immense force and a destructive aura. They quickly dodged as the fist smashed into the ground, creating a massive crater in the hall. The surrounding stone pillars collapsed, sending rubble flying everywhere.

"Everyone be careful, don't get hit by its attack!" Xu Tiancai shouted. While dodging the fist attack, he continued to look for opportunities to attack the Dark Demon.

In the chaotic battle, they discovered that after launching such a large-scale attack, the Dark Demon's body would pause briefly, and after the scales on its abdomen were attacked, the surrounding dark power would become a little disordered.

"After it launches another large-scale attack, we will take advantage of its pause to continue attacking its abdomen!" Xu Tiancai shouted, and they began to adjust their battle strategy, preparing to seize the Dark Demon's weakness.

The Dark Devil attacked again, opening its massive mouth. This time, instead of emitting black flames, it spewed a beam of black energy. The beam shot towards them at an incredible speed, devouring everything in its path, reducing it to nothing.

They quickly dodged as the beam streaked across the hall, destroying some stone pillars and walls. After the beam vanished, the Dark Devil's body paused briefly. They seized this opportunity and launched an even more powerful attack on the Dark Devil's abdomen.

Xu Tiancai channeled all his strength into his lightsaber and thrust it fiercely at the scales, the light emitting from it nearly illuminating the entire hall. Agang leaped high and swung his battle axe at the scales with all his might, the wave of power from the axe causing the surrounding air to tremble. Lin cast a powerful composite spell, fusing the four elements of wind, fire, water, and earth into a massive elemental tiger. The tiger opened its maw and spewed a powerful wave of energy at the scales. The mysterious figure and the Ice Princess each unleashed their most powerful spells. The mysterious figure summoned the destructive power of darkness, while the Ice Princess cast ice magic, forming a massive ice spear that stabbed at the scales.

Their attacks hit the Dark Demon's abdominal scales at the same time. The scales were severely cracked under the powerful attack. The Dark Demon let out a shrill scream, the dark power in his abdomen began to become disordered, and black blood oozed out from the cracks in the scales.

"We succeeded. Keep attacking and don't give it a chance to breathe!" Xu Tiancai shouted. They increased the intensity of their attack, trying to further increase the Dark Demon's injuries.

However, the Dark Devil was not so easily defeated. In the excruciating pain, it unleashed even greater power, and a vast mass of black smoke began to emanate from its body, shimmering with a dark red light. This smoke quickly spread toward them, and wherever it touched, they felt their strength gradually weaken and their bodies grow heavy.

"There's something wrong with this smoke, everyone, get out of here!" Xu Tiancai shouted. They tried to escape from the range of the smoke, but the smoke spread very quickly and soon enveloped them.

Their vision was severely obstructed by the smoke, and they could only see blurry shadows around them. Suddenly, countless black tentacles stretched out from the smoke, their surfaces covered with sharp thorns, and coiled towards them.

Agang swung his battle axe and cut off the approaching tentacles, but the tentacles quickly grew back after being cut off. Lin cast a purification spell to try to disperse the smoke, but the magic was greatly restricted in the smoke and could only barely maintain clarity in a small area.

The mysterious figure and the Ice Princess each cast their own magic. The mysterious figure summoned the devouring power of darkness, attempting to devour the smoke and tentacles, but the smoke and tentacles were too powerful for the devouring power to fully function. The Ice Princess cast ice magic, forming an ice wall around her in an attempt to block the tentacles' attack, but the tentacles easily broke through the ice wall.

"We can't be trapped here. We have to find a way to break through this encirclement of smoke and tentacles," Xu Tiancai said. He merged the power of the stars and the power of the phoenix into a powerful light and shot it in one direction. Wherever the light reached, the smoke was temporarily dispelled, and the tentacles were also burned by the light, creating some gaps.

"Let's rush in this direction!" Xu Tiancai shouted, and they rushed towards the path opened up by the light.

When they rushed out of the smoke, they found that the Dark Demon's injuries had recovered somewhat, the cracks on the scales on its abdomen were gradually healing, and the dark power had stabilized again.

"We can't let it recover, we have to continue attacking!" Xu Tiancai shouted, and they rushed towards the Dark Demon again.

This time, they changed their attack method. Xu Tiancai dispersed his power, forming strands of energy that shone with multicolored light. These strands flew toward the Dark Demon, then entwined themselves around its body, attempting to restrict its movement. Agang, Lin, the mysterious figure, and the Ice Princess attacked other parts of the Dark Demon, distracting it and creating opportunities for Xu Tiancai's attack.

Agang's battle axe chopped at the Dark Demon's leg, trying to make it lose balance; Lin cast a magic spell, turning the surrounding rubble and stone pillars into huge stone balls, and smashed them at the Dark Demon; the mysterious figure summoned the chaotic power in the darkness to disrupt the Dark Demon's perception; the Ice Princess cast ice magic, forming a layer of ice under the Dark Demon's feet, slowing down its movements.

The Dark Devil was somewhat embarrassed by their attacks. It tried to break free from the energy threads, but the threads tightened under Xu Tiancai's control. As it struggled, the scales on its abdomen were once again exposed to their attack range.

"Now, attack its belly!" Xu Tiancai shouted. They seized the opportunity and launched a new round of attacks on the belly of the Dark Demon.

Lin cast a precise spell, channeling water elements into a massive arrow, which she fired at the crack in the scales. The arrow's impact widened the crack, sending black blood gushing out. Agang leaped high and slashed at the scales with his battle axe, sending a shower of black liquid splattering. The mysterious figure and the Ice Princess' magic simultaneously attacked the scales, their combined force finally succumbing to the force and completely shattering them.

The dark demon let out an earth-shattering scream, and a huge wound appeared on his abdomen. Dark power continued to flow out of the wound, and his body began to crumble.

"If we try harder, we can defeat it!" Xu Tiancai shouted, and they launched a final attack on the dark demon.

They gathered all their strength together, forming an incredibly powerful multicolored light. This light rushed towards the Dark Demon, completely dispelling the dark forces wherever it passed. The multicolored light struck the Dark Demon's body, completely enveloping it.

The Dark Demon uttered a shrill cry under the multicolored light. Its body gradually dissipated, its massive silhouette becoming increasingly blurred. With a dazzling flash of light, the Dark Demon completely vanished, leaving behind only a devastated palace.

"We succeeded, the Dark Demon was defeated by us!" Agang shouted excitedly, his face covered with sweat and traces of battle.

"That's right, but we can't relax yet. We have to close the extra-dimensional channel quickly." Xu Tiancai said. He looked at the extra-dimensional channel. The black light at the entrance of the channel had become dim, but there was still some dark power flowing.

They walked towards the extra-dimensional passage. When they approached the passage, a low roar came from inside the passage, as if there was a more powerful existence waiting for them inside the passage.

"No matter what's inside, we can't retreat." Xu Tiancai said, he gripped the artifact tightly and prepared to enter the passage.

The others nodded in agreement, following Xu Tiancai towards the extradimensional passage. As they entered, they felt a powerful suction force, rapidly pulling them deeper into the passage. All around them was darkness, with only the artifacts in their hands and the light on their bodies flickering in the darkness.

After flying through the tunnel for a while, they arrived at a strange space filled with all kinds of distorted light and strangely shaped objects, some like giant eyes peering in the darkness, some like toothy mouths constantly opening and closing, and some like twisted limbs waving.

"Is this another dimension? It feels so weird." Lin said tremblingly, she followed everyone closely.

Suddenly, a group of ghostly creatures emerged from the darkness. Their bodies were transparent, with only a pair of shimmering eyes standing out. They rushed toward them at breakneck speed, emitting sharp cries.

Xu Tiancai combined the power of the stars, the phoenix, and the guardian pearl with the power of the four divine artifacts, forming a series of arrows of light that shone with multicolored light. These arrows shot towards the ghostly creatures, and wherever they reached, the ghosts let out shrill screams and their bodies gradually dissipated.
