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

"It seems that to destroy the poison pool, we must deal with this guardian beast," Lu Lingxi thought to herself, a resolute glint in her beautiful eyes.

"Roar!"

The guardian beast roared to the sky, its sound waves rolling and shaking the entire poisonous pool violently. Its huge, bell-like eyes burned with eerie green flames as it stared intently at Lu Lingxi and the others.

"Master, this big guy is not easy to deal with!" Huan Yue swallowed, his voice trembling slightly. Although he was usually innocent and carefree, he couldn't help but feel nervous in the face of such a terrifying opponent.

“Yes, this aura… is several times stronger than the previous Netherworld Beast!” Phantom’s expression was also very solemn.

Zhuque remained silent, but the phoenix fire on her body burned even more fiercely, the intense heat dissipating some of the surrounding poisonous mist. She stared intently at the guardian beast, ready to launch an attack at any moment.

"Everyone be careful! This guardian beast is likely to have poison attacks, and its scales are extremely strong. Don't get hit by it easily!" Lu Lingxi Yao warned in a deep voice. At the same time, she had already gripped the Flying Snow Sword in her hand. On the blade, four kinds of spiritual power—ice, fire, lightning, and space—flickered alternately, ready to launch a thunderous strike at any time.

The guardian beast seemed to sense the threat posed by Lu Lingxi Yao. It let out a low growl and suddenly opened its blood-red maw, spraying a stream of purplish-black venom like an arrow towards Lu Lingxi Yao.

"Watch out!" Huan Yue exclaimed, wanting to rush forward to help, but it was too late.

Lu Lingxi's eyes sharpened, and with a flicker of her figure, she vanished from her spot. Activating her spatial spiritual power, she teleported directly to the side of the guardian beast, dodging the venom's attack.

"boom!"

The venom landed on the ground, making a sizzling sound as it corroded, instantly creating a large pit and emitting plumes of black smoke.

"Such strong corrosiveness!" Huan Yue and Huan Ying were terrified.

Without pausing, Lu Lingxi Yao swung her Flying Snow Sword, unleashing a chilling sword aura that slashed towards the guardian beast's neck.

"clang!"

The sword energy struck the guardian beast's scales, producing a loud clang of metal against metal, sparks flying everywhere. However, the guardian beast's scales were incredibly hard, and the sword energy only left a shallow white mark on them.

"The defense is so strong!" Lu Lingxi was shocked. She didn't expect the guardian beast to have such amazing defense, which even the Flying Snow Sword could not break through.

"Roar!"

The guardian beast roared in pain, then suddenly turned around, its huge tail lashing out at Lu Lingxi Yao like a steel whip.

Lu Lingxi Yao used spatial teleportation again, narrowly dodging the tail attack.

"Boom!" The guardian beast's tail lashed out at the ground, instantly cracking it and sending debris flying.

"This won't do, we have to find a way to break through its defenses!" Lu Lingxi thought to herself as she dodged the guardian beast's attacks while observing its weaknesses.

"Master, let me help you!"

With a clear cry, the Vermilion Bird transformed into a giant fire phoenix and pounced on the guardian beast. She opened her mouth and spewed out a blazing phoenix fire, which swept towards the guardian beast like a tsunami.

"Roar!" The guardian beast seemed somewhat wary of the phoenix fire; it dared not take it head-on and quickly retreated.

However, the Phoenix Fire was extremely fast and caught up with the guardian beast in an instant, engulfing it.

"Zizi..."

The phoenix fire burned the guardian beast's scales, making a sizzling sound. The guardian beast let out a painful roar, and the black aura on its body quickly dissipated under the scorching of the phoenix fire.

"A good opportunity!" A glint flashed in Lu Lingxi's eyes. She activated spatial teleportation again and appeared above the guardian beast's head.

"Thunder!"

With a delicate shout, Lu Lingxi Yao's Flying Snow Sword crackled with lightning, and thick bolts of lightning, like silver snakes, slashed towards the guardian beast.

"Boom boom boom!"

The lightning struck the guardian beast, producing a deafening roar. The beast's body trembled violently, and charred marks appeared on its scales.

"Roar!" The guardian beast let out a painful howl as it was struck by lightning, its skin torn open and blood gushing out.

"Phantom Moon, Phantom Shadow, you two go too!" Lu Lingxi shouted loudly.

Huan Yue and Huan Ying had been eager to try, and upon hearing Lu Ling Xi Yao's command, they immediately joined the battle.

Illusion Moon transformed into a gust of wind, swirling around the guardian beast. He wielded wind blades, leaving wounds on the guardian beast's body. At the same time, he spewed fireballs from his mouth, combining them with the wind blades to deliver a double blow to the guardian beast.

The phantom then manipulated the Soul-Devouring Vine, which coiled around the guardian beast's limbs and tail like a python. The barbs on the vine pierced the guardian beast's body, absorbing its soul power.

Under the combined attack of Lu Lingxi, Zhuque, Huanyue, and Huanying, the guardian beast gradually fell into a disadvantageous position, with more and more wounds on its body and its aura becoming weaker and weaker.

"Roar!" The guardian beast let out its final roar.

"Oh no, it's going to self-destruct!" Lu Lingxi's expression changed drastically; this guardian beast was surprisingly fierce.

The guardian beast's self-destruction was incredibly powerful, enough to level the entire poisonous pool, and Lu Lingxi, Yao, and the others would definitely not be able to escape.

"Space Imprisonment!"

Lu Lingxi made a decisive move. She used all her spatial spiritual power to build a huge spatial cage around the guardian beast, trapping it firmly inside and preventing it from self-destructing.

"Quick, stop it!" Lu Lingxi shouted.

Vermilion Bird, Phantom Moon, and Phantom Shadow knew the situation was urgent, so they all used all their strength to launch a final attack on the guardian beast.

Phoenix fire, wind blades, fireballs, vines... all sorts of attacks rained down on the guardian beast.

"boom!"

Finally, under the combined attack of Lu Lingxi, Yao and the others, the guardian beast could no longer hold on and let out a shrill wail before its body exploded. However, the power of the explosion was firmly contained within the spatial cage and did not affect the outside.

"call……"

Lu Lingxi Yao let out a long sigh of relief. She felt weak, as her spiritual energy was almost completely depleted. Zhuque, Huanyue, and Huanying were also panting heavily, but they all wore victorious smiles on their faces.

"Finally solved..." Huan Yue said weakly, plopping down on the ground.

"Yes, this big guy is really tough to deal with," Phantom said, still shaken.

"Don't let your guard down, there's still something to resolve!" Lu Lingxi reminded her. She looked at the poisonous pool. Although the guardian beast was dead, the poisonous pool was still there, and the miasma and poisonous fog were still being generated continuously.

"Vermilion Bird, use Phoenix Fire to evaporate the poison in the poisonous pool!" Lu Lingxi said.

"it is good!"

Zhuque responded and transformed into a fire phoenix once more, flying towards the poisonous pool. She opened her mouth and spewed out a stream of blazing phoenix fire, which landed in the poisonous pool and immediately ignited into a raging inferno.

Under the scorching heat of the phoenix fire, the venom rapidly evaporated, turning into a purplish-black poisonous mist that dissipated into the air. As the venom evaporated, the water level in the poisonous pool also continued to drop. Eventually, all the venom in the pool was evaporated completely.
