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

"A good opportunity!" A glint flashed in Lu Lingxi's eyes. She swung her Flying Snow Sword and charged towards the Netherworld Beast.

"Thunder!"

With a soft shout, Lu Lingxi Yao's Flying Snow Sword flashed with dazzling lightning. Bolts of lightning shot out from the Flying Snow Sword and crashed towards the Netherworld Beast. Lightning is the most yang and yang power in the world, and it has a strong restraining effect on yin and evil things.

The Netherworld Beast was struck by lightning, its body trembled, and it let out a painful howl.

"Space Imprisonment!"

Lu Lingxi Yao made her move again, mobilizing the spatial spiritual power within her body to build a spatial cage around the Netherworld Beast.

The spatial cage trapped the Netherworld Beast, rendering it unable to move.

"Die!" A cold glint flashed in Lu Lingxi Yao's eyes as she swung her Flying Snow Sword at the Netherworld Beast.

"Pfft!"

With a soft sound, the head of the Netherworld Beast was severed by the Flying Snow Sword, and its body crashed to the ground, turning into a pile of black ash.

"call……"

Lu Lingxi breathed a long sigh of relief; the battle was finally over.

"Master, you are so amazing!" Huan Yue looked at Lu Lingxi Yao with admiration.

“Yes, Master, you are simply my idol!” Phantom echoed.

"Stop flattering us, we're still not out of danger," Lu Lingxi said.

She looked up into the depths of the poisonous fog; that was where the real danger lay.

"Phantom, can you still sense the location of the poison pool?" Lu Lingxi asked.

"Master, I'll give it a try." Phantom closed his eyes and extended his mental energy into the depths of the poisonous fog.

A moment later, he opened his eyes. "Master, I can sense it. The poison pool is not far ahead."

“Alright, let’s go!” Lu Lingxi said. She sheathed her Flying Snow Sword and, with Vermilion Bird, Illusion Moon, and Illusion Shadow, headed into the depths of the poisonous fog.

As they ventured deeper, the surrounding miasma and poisonous fog grew increasingly dense, and visibility decreased.

Lu Lingxi's voice pierced through the mist, carrying an undeniable authority and vigilance: "Everyone be careful. The dangers lurking in this poisonous fog are far more than this. Perhaps there are even more ferocious evil spirits waiting to strike."

"Yes, Master," Zhuque, Huanyue, and Huanying replied. With an unspoken understanding that they could almost sense each other's breathing, they slowly advanced, cautiously observing their surroundings.

Just then, a sudden gust of cold wind ripped through the oppressive atmosphere like a sharp blade, causing the poisonous fog to surge and churn. Immediately afterward, several dark figures burst out of the fog with astonishing speed. They were surrounded by even denser black energy, exuding an aura of resentment and evil that oppressed everyone's minds.

“Another evil spirit, and…” Phantom’s voice trembled slightly with shock, but was quickly replaced by a firm fighting spirit, “Even more troublesome than before!”

The evil spirits that appeared this time were more powerful than the vengeful spirits and demons before. Their forms were more solid, and they exuded a stronger aura of resentment and malevolence.

“It’s the leader of evil spirits,” Lu Lingxi said solemnly. “The leader of evil spirits is the chief among evil spirits. It is powerful and possesses a certain level of intelligence.”

The evil spirit leader's laughter was sharp and piercing. It held a sharp blade carved from white bones and rushed straight at Lu Lingxi and her group.

"Heh heh, humans, how dare you trespass into the Valley of Rebirth? You're courting death!"

Faced with this arrogant threat, Lu Lingxi Yao's delicate body trembled. She swung her long sword, and with a flash of light, she aimed straight for the evil spirit leader's vitals.

At the same time, the Vermilion Bird spread its wings and soared high, its flames like a phoenix rising from the ashes, hot and pure, burning the approaching evil spirits to ashes.

Huan Yue, with his unpredictable movements, weaved among the evil spirits, each strike precise and ruthless.

The phantom then transforms into a shadow, silently approaching the enemy to deliver a fatal blow.

The evil spirits' attacks were fierce and cruel, but Lu Lingxi and her group cooperated perfectly. As time went by, Lu Lingxi's swordsmanship became increasingly sharp, with each strike carrying the power of dawn, gradually turning the tide of the battle.

Finally, after a brilliant maneuver and counterattack, Lu Lingxi Yao seized the weakness of the evil spirit leader. The Flying Snow Sword, carrying unparalleled sword energy, cleaved through the spatial constraints and delivered a fatal blow to the throat. The evil spirit leader's massive body collapsed with a crash, its resentment scattering into nothingness.

"Phew..." Lu Lingxi Yao breathed a long sigh of relief.

"Master, what do we do now?" Suzaku asked.

"Keep moving forward and find the poisonous pool!" Lu Lingxi said, looking up into the depths of the poisonous fog, where the real target was.

They continued onward, encountering several more waves of evil spirits along the way, but they repelled them all, finally reaching the edge of the poisonous pool.

Ahead lay a huge, circular pool of water, churning with purplish-black venom that emitted a nauseating, foul stench.

"This is the Poison Pool?" Huan Yue exclaimed in surprise as she looked at the scene before her.

"This venom is probably even corroding black iron," Phantom said.

“This poisonous pool is the source of the miasma and poisonous fog. As long as we destroy it, we can solve the problem of the miasma and poisonous fog,” Lu Lingxi Yao said.

"Master, let me do it!" Zhuque volunteered, her body ablaze with phoenix fire as she charged toward the poisonous pool.

"Be careful!" Lu Lingxi Yao warned.

Zhuque nodded, took a deep breath, and suddenly opened her mouth, spewing out a blazing flame. The phoenix fire, carrying the power to purify all evil, rushed towards the poisonous pool.

With a loud "boom," the venom in the poisonous pool was ignited by the Phoenix Fire and burst into flames.

"Roar!"

Suddenly, a deafening roar came from the poisonous pool, followed by a huge figure bursting out of it.

This figure was even larger and more terrifying than the previous Netherworld Beast. It was covered in black scales, had a single horn on its head, a ferocious face, and spewed poisonous mist from its mouth.

"What kind of monster is this?" Huan Yue exclaimed.

“It must be the guardian beast of the poisonous pool!” Lu Lingxi’s expression turned solemn.

This guardian beast was stronger than the Netherworld Beast and the Evil Spirit Leader they had encountered before. It exuded a terrifying aura, which made Lu Lingxi feel a bit of pressure.
