The genius who counterattacked the mainland

As they entered the cave, a damp, ancient air washed over them. The cave was eerily quiet, with only the sound of their footsteps echoing in the empty space. Each step seemed to tread on the strings of history, playing a mysterious note.

Xu Tiancai walked in front, the light from the Star Demon-Breaking Sword illuminating a small area ahead. The patterns and runes on the wall seemed to come alive under the sword's glare, their mysterious lines flowing, telling stories of ancient legends. Some runes shimmered with a faint blue light, like distant, cold stars in the night sky; others glowed a dark red, like congealed ancient blood.

"These runes and patterns seem to be guiding something. Everyone, please pay attention to whether there are any special places around." Xu Tiancai said softly, his voice echoing in the cave with a hint of ethereality.

Ah Gang gripped his battle axe tightly and glanced around vigilantly, "It feels eerie in here, everyone, be alert, there might be some traps."

Lin cast a small magic of wind element, letting a gentle breeze surround them. "I can feel that the flow of wind in this cave is a little strange. It seems that there are some hidden passages." The wind element is like a sensitive tentacle, exploring the unknown corners of the cave.

The Ice Princess waved her wand, and the crystal on the top of the wand emitted a faint blue light, illuminating the slippery ground beneath her feet. "The ground is a bit slippery. There may be water or other special substances. Everyone, be careful not to fall."

The mysterious figure and the man in white followed behind, always prepared for any possible danger. The mysterious figure formed a subtle seal with his hands, sensing the energy fluctuations within the cave. "The energy here is complex. There's an aura of ancient seals, and some unknown force surges." The man in white then began to play a flute. The notes were deep and melodious, as if he were conversing with the mysterious force within the cave, trying to gain information from it.

As they walked, a huge stone carving appeared on the side of the cave. The carving depicted a war scene, similar to the one they had seen in the light and shadow of the basement, but more detailed. The warriors in the scene were lifelike, harnessing the power of various elements to fight against the dark creatures. Some warriors wielded weapons that emitted powerful wind blades, capable of slicing dark creatures into pieces; some warriors summoned giant icicles to freeze them; and others, their bodies ablaze with flames, engaged the dark creatures in close combat. The dark creatures varied in form: some had enormous wings that blocked out the sky; some were serpent-like, weaving through the ground and suddenly leaping out to attack the warriors; and some were giant humanoid monsters, wielding black weapons and exuding the aura of death.

"Look at these stone carvings. The battle between the ancient civilization and the dark forces was too tragic. We must find a way to completely eliminate the dark forces and not let such a tragedy happen again." The Ice Princess looked at the stone carvings, a hint of determination flashing in her eyes.

As they continued deeper, the cave began to slope downward, and the ground became increasingly slippery. Suddenly, they heard the sound of gurgling water ahead. Approaching, they discovered an underground river stretching before them. The water flowed rapidly, and a strange light shimmered on the surface, as if countless gems were gleaming beneath the river.

"This river doesn't look simple. How can we cross it?" A Gang looked at the river with a frown.

Lin squatted down and touched the river water with her hand, and immediately felt a biting cold. "This river water is so cold, and it seems to have magic. I can't go into the water easily."

Xu Tiancai observed the surroundings and noticed some faintly visible stones on the river surface. These stones were arranged in a certain pattern, like a path across the river. "Look at those stones, they might be a passage across the river, but we have to be careful, as we don't know if these stones are stable."

Everyone stepped cautiously onto the stones. Xu Tiancai walked in front, testing the stability of each one with his Star Devil-Breaking Sword. As he stepped onto a stone, it swayed slightly, and the surrounding river water suddenly surged, forming a wave that rushed towards him. Xu Tiancai swiftly swung his sword, and the power of the stars split the wave apart.

"Everyone be careful, the river water will attack us, cross the river quickly!" Xu Tiancai shouted.

They sped up, struggling to cross the river under the onslaught of the waves. Gang swung his battle axe, shattering the approaching waves. Lin cast wind magic, creating a wind shield to resist the waves. The Ice Princess summoned an ice shield to strengthen her defenses. The mysterious figure and the man in white also used their powers to protect themselves and their companions.

After much effort, they finally crossed the river. As soon as they reached shore, they discovered an ancient stone gate by the river. The gate was engraved with intricate runes and patterns, which emanated powerful energy fluctuations.

"This stone door must lead to an important place. We must open it." Xu Tiancai said.

Everyone gathered around the stone gate and began to study the runes on it. Lin used the wind element to sense the flow of energy in the runes, discovering some subtle connections between them. "The energy flow of these runes is like a chain reaction. We need to find the order to activate them."

Ah Gang analyzed it from the perspective of strength, "These runes are very powerful. If they are triggered in the wrong order, it may cause danger."

The Ice Princess sensed the runes through ice magic. "Some runes have special reactions to ice magic. We can start from there."

The mysterious figure and the man in white tried to interpret it from the perspective of energy and music. "The energy fluctuations of the runes are similar to the rhythm of music. We need to find the right melody to open the stone door."

After a long period of research and experimentation, everyone finally found a way to open the stone door. Xu Tiancai touched the runes in order, and the light on the stone door brightened. With a low roar, the stone door slowly opened.

Behind the stone gate was a massive hall with a towering dome inlaid with countless enormous crystals. These crystals radiated a multicolored light, illuminating the entire hall like a dreamscape. In the center of the hall sat a massive stone platform, upon which rested a crystal ball emitting an intense glow. This crystal ball was larger than any they had ever seen before, and its light was even more dazzling, as if it contained the secrets of the universe.

"This crystal ball... must contain a vital secret." Xu Tiancai looked at the crystal ball in surprise, his eyes flashing with excitement.

Everyone walked towards the stone platform. When they approached the platform, the air around them suddenly became heavy, and a strong pressure came over them.

"What a powerful force, everyone be careful." Agang felt the pressure and tightened his grip on the battle axe.

At this moment, several rays of light shot out from the crystal ball, forming several illusory figures in the hall. These figures varied in form: some resembled ancient warriors, clad in heavy armor and wielding longswords; some resembled mysterious magicians, holding wands and surrounded by elemental light; and still others resembled lively elves, with transparent wings growing from their backs, emitting a natural aura.

"Who are you? Why did you break in here?" An illusory figure that looked like a warrior spoke in a majestic and loud voice.

Xu Tiancai stepped forward and said, "We are here to explore the ruins and find a way to eliminate the dark forces. We have no intention of offending you, but we hope to use the power here to fight against the darkness."

"Hmph, you want to borrow the power here? This is the holy land we guard, not a place you can casually set foot in." The illusory figure that looked like a magician said, and with a wave of the magic wand in his hand, a beam of magic light shot towards everyone.

Xu Tiancai quickly raised his Star Devil-Breaking Sword to block the magic beam. The sword and the beam collided, splashing a brilliant light.

"It seems we have to fight to move forward." A Gang said, waving his battle axe and rushing towards the illusory figure that looked like a warrior.

Lin cast wind magic, creating powerful wind blades that shot towards the phantom magician. The blades sliced ​​through the air, emitting a sharp whistling sound as they flew towards their target. The Ice Princess waved her wand, summoning a massive ice cone, which pierced the phantom elf. The cold magic of the ice cone condensed into a layer of frost in the air.

The mysterious figure quickly formed hand seals, and the forces of darkness and light merged in his hands into massive energy chains, which wrapped around the illusory figures. The man in white played the flute, and the sound transformed into a group of shimmering light beasts, which rushed towards the illusory figures and engaged them in battle.

A phantom warrior swung his sword, clashing with Agang's axe in a shower of sparks. The warrior's swordsmanship was sharp, each stroke imbued with immense power. Agang felt immense pressure, but he remained steadfast, engaging the warrior in a fierce battle. Axe and sword clashed, creating a resounding metallic clash that echoed throughout the hall.

Lin's wind blades attacked the illusory figure resembling a magician, but the magician easily blocked them with a magic shield. The magician muttered to himself, and a stream of magic spells flew out of his mouth, transforming into various magical attacks, attacking Lin and the others. Lin continuously created wind tornadoes to resist the magician's attacks, while searching for the magician's weaknesses.

The Ice Princess thrust her icy spikes at the ethereal figure, but the elf, nimble and agile, easily dodged the attack. The elf danced through the air, shedding rays of light. These rays fell to the ground, sprouting vines and thorns that entwined themselves around the group. The Ice Princess waved her wand, summoning icy flames that burned away the vines and thorns.

During the battle, Xu Tiancai discovered that these illusory figures seemed to be transformed by the power of the crystal ball, and there was some kind of energy connection between them.

"Everyone, please pay attention. These illusory figures are interconnected. We need to find a way to cut off their connection in order to better deal with it." Xu Tiancai shouted.

As they fought, everyone kept an eye on the connections between the phantom figures. During the fierce battle, Xu Tiancai discovered that whenever the phantom figures launched a joint attack, a faint beam of energy would connect them.

"Attack those energy rays!" Xu Tiancai shouted.

Everyone adjusted their attack direction and launched an attack towards the energy beam. Xu Tiancai wielded the Star Demon-Breaking Sword, slashing at a beam of energy. The power of the stars cut through the energy beam. Agang's battle axe, Lin's wind blade, the Ice Princess's ice spike, the mysterious figure's energy chains, and the white-clothed man's light beast also attacked the energy beam.

As the energy beams were cut off, the phantom figures' attacks became somewhat chaotic. Their coordination was no longer seamless, and their power was weakened.

"Now is the time, everyone increase the intensity of the attack!" Xu Tiancai shouted.

Everyone seized the opportunity and launched a more fierce attack on the illusory figure. Agang raised his fighting spirit to the extreme, and a blazing golden flame ignited on his battle axe, and he chopped hard at the illusory figure that looked like a warrior. The battle axe hit the warrior's armor, and this time it successfully cut through the armor. The warrior's body swayed slightly. Lin cast a forbidden spell of wind element magic. She gathered all the surrounding air and compressed it into a huge air bomb, throwing it at the illusory figure that looked like a magician. The air bomb exploded next to the magician, and the powerful impact caused cracks in the magician's magic shield. The Ice Princess waved her wand and summoned a huge ice giant. The ice giant walked towards the illusory figure that looked like an elf, and with every step, a thick layer of ice formed on the ground. The ice giant waved his huge fist and smashed towards the elf.

The mysterious figure rapidly formed hand seals, and the forces of darkness and light merged in his hands into a massive ball of energy. This ball of energy contained the powerful force of the laws. He threw the ball of energy at a group of illusory figures, and it exploded among them, the powerful energy shockwave shaking several of them off balance. The figure in white played the flute at full speed, and the sound of the flute transformed into enormous luminous beasts. These beasts varied in form: a phoenix ablaze with flames, a roc soaring with wings spread, and a qilin running at lightning speed. The beasts rushed towards the illusory figures, fighting with their own strength. The phoenix burned the illusory figures with its flames, the roc tore at their defenses with its claws, and the qilin shuttled between the figures, disrupting their attack rhythm.
