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

“This demonic poison…” Zhu Yin said solemnly, “is indeed of the same origin as the one in Young Master Nalan’s body.”

Mo Xinghe grinned maliciously, "That's right, this is a unique secret technique of our Dark Star Pavilion. Back then, we used this demonic poison to severely injure the little prince of the Demon Realm. Now, you will also taste this flavor!"

"So it was you!" Lu Lingxi's eyes flashed with killing intent, and the nine elements of spiritual power circulated wildly within her body.

A cold glint flashed in Huan Yue's eyes, and wind and fire elemental spiritual power condensed in her fair palm. "Master, let me deal with these scum!"

Phantom also stepped forward, his tall figure accentuated by his black outfit. "We've been cultivating in the spirit beast space all these years, just so we can lend a helping hand when our master needs us."

"Overestimating yourself!" Mo Xinghe sneered, brandishing his longsword as demonic energy transformed into countless black blades that attacked the crowd.

Lu Lingxi Yao's Flying Snow Sword emitted a clear and melodious dragon's roar. The sword light collided with those black blades. Huan Yue's figure was as fast as lightning. Wind and fire intertwined to form a blazing light wheel, forcing back several mirror-wielders. Huan Ying manipulated vines to break through the ground and entangle the enemy.

"Master!" came the anxious voice of the Vermilion Bird from the Kunlun Ring, "Let me out to help you!"

"No!" Lu Lingxi said while fiercely fighting Mo Xinghe, "Your injuries haven't healed yet!"

Just then, the Demon Poison Array suddenly fluctuated violently, and countless black mists surged towards the center of the array, condensing into a huge vortex. A hint of madness flashed in Mo Xinghe's eyes, "The power bestowed by the Lord, let you taste it!"

Countless black tentacles suddenly emerged from the vortex, each containing deadly demonic poison. Zhu Yin played a soft note on his bamboo flute, and streams of azure energy swept out, severing the tentacles. However, these tentacles continued to regenerate, making them impossible to eradicate completely.

"This can't go on," Zhu Yin said in a deep voice, "The demonic poison will only get stronger!"

A resolute glint flashed in Lu Lingxi's eyes. She suddenly sheathed her sword and stood still, her nine elements of spiritual power erupting simultaneously, forming a nine-colored pillar of light that shot into the sky.

"Master!" Huan Yue and Huan Ying exclaimed simultaneously.

"Don't worry," Lu Lingxi Yao said with a cold smile, "Since they used demonic poison to harm Rong Zhi, today we'll let them taste the same thing!"

Nine-colored pillars of light intertwined in the air, forming a massive light array that countered the demonic poison array. Mo Xinghe's expression changed drastically. "This is... a nine-elemental spiritual power array? Impossible! Even a master of all elements couldn't control nine elements of spiritual power simultaneously!"

"That's because you know nothing about the power of all elemental spirit masters!" Lu Lingxi Yao formed hand seals, and the nine-colored light array suddenly contracted, shredding the demonic poison array layer by layer.

Mo Xinghe and the others were forced to retreat by the force, and the bone mirrors in their hands shattered one after another. Just then, a dark figure suddenly appeared behind Mo Xinghe and struck him in the back with a palm.

"Pfft!" Mo Xinghe spat out a mouthful of blood and turned around in disbelief, only to see that the phantom had appeared behind him at some point.

“Master is right,” a cold glint flashed in Phantom’s eyes, “It’s time for you to taste the poison.”

Countless demonic blood vines coiled around Mo Xinghe's body, and the toxins seeping from the vines quickly invaded his meridians. Mo Xinghe let out a shrill scream, and his body began to twist and deform.

"My lord... save me..." he cried out one last time before his body turned into a pool of black water. The other members of the Dark Star Pavilion scattered and fled.

"Don't let them get away!" Lu Lingxi was about to give chase, but Zhu Yin stopped her. "The Star Grass is more important. These small fry are nothing to worry about."

Lu Lingxi nodded, and the four of them cautiously approached the area where the stars were twinkling. As they got closer, a dense stellar power rushed towards them. Huan Yue's eyes flashed with amazement, "Such powerful stellar power!"

The earth's veins suddenly trembled spasmodically, and countless cracks burst open from the scorched earth under the blood-red moonlight. Wraiths carrying stardust broke through the soil, their skeletons covered with humus tentacles, and thousands of throats resonated with ear-piercing screams.

Zhu Yin staggered, steadying himself on the broken monument. His jade hairpin shattered from the tremor, and cold sweat beaded on his dark hair. "The Soul-Devouring Miasma of the Starfall Mountains...it's already seeped into the earth's veins!"

Before she finished speaking, Huan Yue's toes touched the stardust on the ground, and as her long green silk sleeves billowed, a raging inferno of karmic fire ignited around her. The wind howled and the fire roared together to form a spiraling hurricane, and wherever it passed, the skeletons of vengeful spirits were shredded into phosphorescent dust, exploding into a continuous stream of emerald fireworks under the night sky.

Ten feet away, a wooden spirit talisman appeared in the phantom's palm, and hundreds of jade vine snakes instantly sprang out from the bluestone slab. The gnarled branches, wrapped with ice crystals, grew wildly, building a jade Great Wall covered with thorns.

The Flying Snow Sword shone with a cold light in Lu Lingxi Yao's hand. Nine-colored spiritual light coiled around the sword like a dragon, and wherever the sword's edge passed, the vengeful spirits turned into dark light and dissipated.

Beneath the blood-red sky, a black tide surged. The evil spirits that had been slain had not yet dissipated, and newly arrived malevolent spirits had already climbed the sword blade like a malignant tumor, staining the gleaming edge dark red.

Blood seeped from the tiger's mouth where she gripped the sword, but the frost flowers formed by her spiritual energy shone even brighter, drawing streaks like the Milky Way in the eternal night.

"Master, look!" Huan Yue suddenly pointed ahead, her voice filled with surprise.

Amidst the dense swarm of vengeful spirits, a shimmering, crystalline herb sways gently. On its leaves, tiny specks of starlight resemble the stars in the night sky. This is the Star Grass that people dream of!

"I'll go pick it!" Phantom moved and was about to step forward, but Zhu Yin stopped him with a hand. "Wait, the vengeful spirits around the Star Grass are the most ferocious."

Upon hearing this, Lu Lingxi took a deep breath and said, "You will hold off these vengeful spirits for me. I will go and retrieve the Star Grass myself."

"Master, be careful!" Huan Yue and Huan Ying shouted in unison, their voices full of concern.

Lu Lingxi Yao skillfully fused the nine elements of spiritual power with sword energy. With each swing of her longsword, the vengeful spirits were shredded layer by layer. Her figure nimbly weaved through the horde of vengeful spirits. Finally, she arrived in front of the Star Grass. However, just as she was about to reach out and pluck it, a powerful suction suddenly surged from the ground, attempting to drag her into the abyss.

"Master!" Huan Yue and Huan Ying exclaimed simultaneously. The former manipulated the power of wind and fire, while the latter released vines to entwine and try to save Lu Ling Xi Yao.

At this critical moment of life and death, a dazzling seven-colored flame suddenly erupted from the Kunlun Ring. Despite its severe injuries, the Vermilion Bird resolutely rushed out of the ring, its wings as brilliant as the sunset. "Master, grab me quickly!"

Lu Lingxi grabbed the hand that Zhuque reached out to her, and with her other hand quickly plucked the Star Grass. Zhuque flapped its wings and flew high, carrying her into the air, narrowly avoiding the deadly suction force.

"Zhuque, your injuries..." Lu Lingxi looked at Zhuque with concern.

"It's alright." Zhuque forced a smile, though the smile was somewhat weak.

"Run!" Zhu Yin suddenly shouted, "The power underground is constantly increasing!"

The five dared not delay and quickly retreated. The vengeful spirits behind them let out unwilling roars, but they were powerless to chase after them.

When they returned safely to the foot of the mountain, Lu Lingxi finally breathed a sigh of relief, looking down at the Star Grass in her hand, a hint of barely perceptible joy in her eyes.
