Genius in the whole system: The useless young lady dominates the world

A biting sea breeze rushed towards her, carrying a strong salty smell. Lu Lingxi squinted as she surveyed the boundless blue sea before her. "The Endless Sea truly lives up to its name."

Nalan Rongzhi took her hand, the familiar warmth from her fingertips reassuring her. He said, "Let's go, let's find a place to stay first, then investigate the whereabouts of the Dragon Tomb."

They found an inconspicuous island and rested there temporarily. Lu Lingxi used her spiritual power to explore the surroundings and discovered that the spiritual energy in this sea area was chaotic, with undercurrents and unknown dangers lurking.

Nalan Rongzhi took out an ancient sea chart from his storage ring and studied it carefully. According to the sea chart, the Dragon Tomb was located in the center of the Endless Sea, with an extremely hidden entrance and powerful protective barriers.

The next day, they flew in the direction marked on the sea chart, riding on Nalan Rongzhi's flying artifact. Along the way, they encountered various strange sea beasts, but they were all repelled by Lu Lingxi and Nalan Rongzhi working together.

On the third day, as they ventured deeper into the endless sea, the color of the water gradually deepened, changing from azure to dark green, and finally almost turning black, like the gaping maw of an abyss.

Finally, they arrived at the location marked on the nautical chart. Before them lay a massive whirlpool, the seawater churning and roaring with a deafening sound.

Lu Lingxi felt a powerful suction force, as if it was going to tear her away from Nalan Rongzhi. She subconsciously grabbed Nalan Rongzhi's hand tightly.

Nalan Rongzhi turned his head, his deep eyes reflecting swirling light and shadow, a fleeting hint of worry flashing across his face. "Hold on tight to me," he said, his voice carrying a reassuring strength.

Then, Nalan Rongzhi summoned a defensive magic weapon, which emitted a faint golden light that enveloped them. Without hesitation, he pulled Lu Lingxi and Yao Yao into the vortex.

Suddenly, the world spun around her. Lu Lingxi closed her eyes tightly, her stomach churning, and the intense feeling of weightlessness made it almost impossible for her to breathe.

After an unknown amount of time, the spinning finally stopped. They were swept into the depths of the sea by a powerful undercurrent. The defensive magic artifacts trembled violently, emitting sounds of being unable to bear the strain, and the golden light became flickering, as if it would be extinguished at any moment.

A strong sense of unease rose in Lu Lingxi's heart: this Dragon Tomb was even more dangerous than she had imagined.

The seabed was pitch black, with only the faint golden light emitted by the defensive magic weapon illuminating a small area around it. Lu Lingxi tried hard to open her eyes, but could only see darkness.

"Are you alright?" Nalan Rongzhi's voice rang in Lu Lingxi's ears, tinged with concern.

"I'm fine." Lu Lingxi took a deep breath, trying to calm her churning stomach acid and uneasy emotions. "It's just that this undercurrent seems a bit strange." The power of this undercurrent is unusually strong, and its direction is unpredictable.

"Be careful, we know nothing about the situation inside the Dragon Tomb." Nalan Rongzhi's voice was tinged with seriousness.

They drifted with the undercurrent, like two rootless duckweeds, surrounded by silence, with only the sound of the surging undercurrent and the vibration of the defensive magic weapon.

Suddenly, Lu Lingxi felt a powerful spiritual energy fluctuation coming from ahead. This spiritual energy fluctuation was ancient and mysterious, carrying a chilling pressure.

"There's something ahead!" Lu Lingxi said in a low voice, while circulating her spiritual power to prepare for battle.

Nalan Rongzhi also noticed the anomaly ahead. He maximized the power of his defensive magic weapon, which shone brightly with golden light, firmly protecting them within.

The current was getting faster and faster. It was as if they were being pushed by an invisible hand, rushing towards the direction of the spiritual energy fluctuation. The darkness in front of them gradually dissipated, and in its place was a faint blue light. As they got closer, they finally saw the source of the light.

It was a huge crystal palace, standing silently deep in the sea. The palace was made entirely of a crystal that emitted a faint blue light, crystal clear and beautiful.

Surrounding the palace are countless strangely shaped corals and seaweeds, which, illuminated by a deep blue light, look like a dream.

"This is the core of the Dragon Tomb?" Lu Lingxi Yao couldn't help but ask.

They were carried by the undercurrent to the entrance of the palace, where two huge crystal doors were tightly closed, engraved with mysterious dragon patterns.

"It seems this is the entrance to the Dragon Tomb." Lu Lingxi looked at the huge crystal door in front of her, her heart filled with anticipation and a trace of unease.

Nalan Rongzhi remained silent. He reached out and gently stroked the dragon pattern on the crystal door, his brows furrowed as if he were deep in thought.

Suddenly, the crystal door opened with a soft click.

A powerful suction force came from inside the crystal door, pulling Lu Lingxi and Nalan Rongzhi inside. After a dizzying moment, they crashed heavily to the ground.

Lu Lingxi groaned and struggled to sit up, rubbing her sore bottom. Nalan Rongzhi caught her in his arms before she hit the ground, so she only shuddered slightly and was unharmed.

"Yaoyao, are you alright?" he asked with concern, his deep eyes filled with worry.

Lu Lingxi shook her head, stood up, and began to look around at her surroundings.

Inside the palace, everything was resplendent in gold and jade. Countless enormous luminous pearls were embedded in the walls, illuminating the entire palace as if it were daytime. In the center of the palace, there was a huge crystal throne. The throne was empty, yet it emanated a powerful spiritual energy.

They cautiously surveyed their surroundings but found no trace of any living creature. An ancient and mysterious aura permeated the air, creating an inexplicable sense of oppression.

"It seems a bit too quiet here," Lu Lingxi said softly, a bad feeling rising in her heart. She summoned the Flying Snow Sword, her spiritual power circulating quietly within her body, ready to deal with any sudden danger.

Nalan Rongzhi also sensed something was wrong. He shielded Lu Lingxi Yao behind him, exuding a chilling killing intent.

Just then, a strange laugh suddenly rang out in the palace, sending chills down everyone's spine.

"Hahaha... Welcome to my palace, my two little guests."

After the laughter subsided, a figure emerged from behind the crystal throne. It was a hunched old man wearing a black robe, his face covered with wrinkles, and his cloudy eyes gleaming with a cold light.

"Who are you?" Lu Lingxi asked coldly, her eyes fixed warily on the old man.

The old man gave a sinister smile, revealing a set of yellow teeth: "I am the Dark Night Protector, you can call me... Black Robe."

"Dark Night Protector? You're from the Dark Organization? What are you doing here?" Lu Lingxi asked.

The man in the black robe extended a withered finger and pointed to the crystal throne: "Of course, it's for the Dragon Tomb's most precious treasure—the Heart of the Dragon God."

"The Heart of the Dragon God?" Lu Lingxi and Nalan Rongzhi exchanged a glance, seeing surprise in each other's eyes. Legend has it that the Heart of the Dragon God contains the power of the Dragon God, possessing the power to destroy the world.

“That’s right.” A glint of greed flashed in the black-robed man’s eyes. “If I obtain it, I will possess unparalleled power and rule the entire world!”

"Wishful thinking!" Lu Lingxi sneered. "How could I let the Heart of the Dragon God fall into your hands!"

"Hmph, little girl, you've got quite the nerve." A sinister glint flashed in the black-robed man's eyes. "You two think you can stop me?"

Before the words were finished, the man in black robes suddenly made his move, and a powerful black spiritual force surged towards Lu Lingxi and Nalan Rongzhi like a tidal wave.

Nalan Rongzhi snorted coldly, and a black demonic sword suddenly appeared in his hand. With a swing of the demonic sword, a sharp sword aura blocked the attack from the black-robed man.

"Yaoyao, be careful, this guy is quite strong," Nalan Rongzhi said in a deep voice.

Lu Lingxi nodded. She channeled her spiritual power into the Flying Snow Sword. With a gentle wave, the sword energy transformed into dazzling attacks, hurtling towards the black-robed figure.

Not to be outdone, the man in black robes conjured a ball of black energy in his hand and hurled it fiercely at Lu Lingxi Yao.

Lu Lingxi Yao dodged the energy ball attack with a flash, and then swung her long sword again, sending a golden sword aura straight towards the black-robed man.

The man in black robes snorted coldly, his figure transforming into a black shadow as he dodged the sword energy attack.

In an instant, spiritual energy surged within the palace, and the two sides fought back and forth, locked in a fierce and evenly matched battle.

Although Lu Lingxi Yao is a full-elemental spirit master, the black-robed man, as a protector of the dark organization, is also quite powerful. Moreover, the black-robed man seems to be very familiar with the terrain of the Dragon Tomb. He used various mechanisms and traps in the palace to cause a lot of trouble for Lu Lingxi Yao and Nalan Rongzhi.

"Damn old man, how could he be so insidious!" Lu Lingxi cursed inwardly, dodging the black-robed man's attacks while searching for his weakness.

Just then, the man in the black robe let out a strange laugh, and a black skull appeared in his hand.

"Little girl, taste my necromancy!"

The black-robed man tossed the skull into the air, and the skull immediately emitted a piercing scream. A black mist spread out, enveloping the entire palace.

Lu Lingxi and Nalan Rongzhi immediately felt a cold aura invade their bodies, and their spiritual energy circulation became sluggish.

"Not good! This curse of the dead can corrode spiritual power and soul!" Nalan Rongzhi's expression changed, and his purple pupils suddenly contracted. He quickly activated his magic power, and a thick layer of black mist instantly enveloped him and Lu Lingxi Yao, like an indestructible cocoon.

However, the power of the Curse of the Dead, like a maggot clinging to a bone, continuously eroded Nalan Rongzhi's demonic energy defense. The black mist churned violently, making a hissing sound, as if it were being scorched by a raging fire.

Lu Lingxi felt a bone-chilling cold sweep over her entire body, as if her body was filled with lead, becoming heavier and heavier. The spiritual power within her body also began to become chaotic and uncontrollable. The world before her eyes gradually blurred and distorted, and countless ferocious undead bared their fangs and claws before her, letting out mournful howls, as if they wanted to drag her into an endless abyss.

"Yao Yao!" Nalan Rongzhi's voice was filled with anxiety and worry. He held Lu Lingxi tightly, trying to use his body heat to dispel the chill from her body. "How are you?"

Lu Lingxi gritted her teeth, enduring the excruciating pain from the depths of her soul, and struggled to remain conscious. She knew that if she collapsed, Nalan Rongzhi would also be in danger; she absolutely could not become a burden to him!

Just then, a powerful suction force came from the crystal throne, pulling the two of them tightly together. Lu Lingxi felt dizzy and everything in front of her became blurry.

"Hold on tight!" Nalan Rongzhi's voice rang in her ears.

Lu Lingxi Yao subconsciously grabbed Nalan Rongzhi's hand, their fingers intertwined. She could feel the warmth of his palm and the strength from his fingertips, which made her feel a sense of security.

The suction grew stronger and stronger, and the two of them, like kites with broken strings, were carried by that force to an unknown place.
