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

In the Ghost Realm, there is no direction, no concept of the passage of time. Lu Lingxi, Yao, and the other two followed the aura left by the Black Abyss and traveled through this void.

"Shoot-"

A tiny spatial rift appeared silently beside Lan Yuan. At this critical moment, Nalan Rongzhi grabbed him and pulled him away from his original spot. The rift instantly expanded, swallowing the place where they had just stood.

"Thank you, Demon Lord." Lan Yuan broke out in a cold sweat.

"Be careful, there are more and more spatial traps here." Nalan Rongzhi's voice was cold and detached.

Lu Lingxi's phoenix eyes narrowed slightly. With the Azure Dragon Sword in hand, she warily scanned her surroundings. She sensed that as she ventured deeper, this ghostly realm was fraught with deadly dangers.

"Roar!"

A violent roar came from the thick fog ahead, and several powerful black figures pounced out. The figures were solid in shape, with human-shaped outlines that could be vaguely seen. They were surrounded by dense black energy, with bloodshot eyes, and held weapons formed from Yin energy in their hands.

"It's a vengeful spirit, stronger than a wandering ghost, and it retains some of its fighting instincts!" Lu Lingxi said in a low voice. The Azure Dragon Sword flashed with a dazzling sword flower, instantly slicing the first vengeful spirit in two.

Nalan Rongzhi made a fist with both hands, and a ball of purplish-black demonic flame roared out, exploding violently among the horde of vengeful spirits. The violent demonic energy, carrying destructive elemental power, blasted several vengeful spirits to smithereens.

Lan Yuan formed hand seals, and strands of azure chains emerged from the void, binding the vengeful spirits that attempted to attack from the flanks. The water-based divine power carried a purifying intent, and the vengeful spirits let out mournful screams, their movements becoming sluggish.

The three worked together seamlessly, and after a fierce battle, all the vengeful spirits were wiped out.

Lu Lingxi Yao breathed slightly and looked at Nalan Rongzhi, "The people from Black Abyss can move freely in here, so they must have special methods."

Nalan Rongzhi nodded: "They cultivate evil and wicked techniques, so they are more adaptable to this kind of environment. Moreover, they seem to have a clear goal, unlike us who need to figure things out."

"Master, the Yin energy ahead seems to be even stronger. I can sense an extremely powerful resentment." Lan Yuan suddenly spoke, his azure eyes flashing with a solemn light.

The three exchanged a glance and cautiously moved forward. As they passed through a small hill made of bones, the sight before them made their hearts sink. It was a vast ancient battlefield ruin, with tattered flags stuck in the ground, broken weapons everywhere, and countless ghostly figures swirling and howling in the sky above the battlefield, forming a huge cloud of souls.

In the center of the battlefield, a towering ghost figure, several meters tall, clad in tattered armor and wielding a giant axe, stood silently. The terrifying resentment and malevolent aura emanating from him sent chills down one's spine.

"Is this a remnant soul sealed away in ancient times?" Lu Lingxi felt the astonishing pressure and her expression turned solemn.

"Judging from his attire, he must have been a valiant and skilled general in his lifetime." Nalan Rongzhi's purple eyes narrowed slightly.

Just as they were observing, the general's remnant soul seemed to sense the presence of the living. Two crimson spots suddenly lit up in his empty eye sockets. He let out a deafening roar filled with resentment and anger. With a swing of his giant axe, a murderous aura carrying the power to split mountains and shatter rocks swept towards the three of them!

"Such a powerful attack!" Lu Lingxi's pupils contracted, and the Azure Dragon Sword instantly erupted with a dazzling azure light, pouring in the power of chaos without reservation. "Azure Dragon Roar!"

A resounding dragon roar echoed throughout the ghost realm, and a huge azure dragon shadow roared out from the sword, heading towards the malevolent aura.

"boom!"

The two powerful forces collided, unleashing an astonishing energy shock. The surrounding soul clouds were scattered considerably, and both the Azure Dragon Sword Shadow and the baleful aura dissipated. Lu Lingxi felt a numbness in her arm and her body swayed slightly.

"This remnant soul actually retains such powerful strength from its lifetime!" A hint of surprise flashed in Nalan Rongzhi's eyes, followed by a surge of fighting spirit. "Yaoyao, I'll lead the attack, you provide support!"

Before he finished speaking, he had already transformed into a streak of light and rushed forward, with the spiritual power of the ten elements surrounding him, and demonic energy covering his entire body like armor.

"Ten Thousand Demons Devour Souls!" Nalan Rongzhi roared, and countless demonic shadows formed from demonic energy swept towards the remnant soul.

The remnant soul roared repeatedly, wielding its giant axe with tremendous force, carrying a heavy pressure and intense baleful aura, shattering the demonic shadows one by one. However, it was ultimately just a remnant soul, and its movements were somewhat sluggish.

Lu Lingxi seized the opportunity, circled around to the side and rear of the remnant soul, unleashed the Azure Dragon Sword Technique, and the sword light rained down, accurately stabbing at the relatively weak points of its energy. The power of chaos continuously eroded the evil aura on the surface of the remnant soul's body.

Lan Yuan formed hand seals repeatedly, and a series of azure halos appeared beneath the remnant soul's feet, attempting to restrict its movements. At the same time, he conjured a huge water mirror, placing it in front of Lu Lingxi Yao and Nalan Rongzhi to block the scattered residual waves of evil energy.

"Dang! Dang! Dang!"

The Azure Dragon Sword and the giant axe clashed repeatedly, and Nalan Rongzhi's attacks became increasingly ferocious, unleashing a barrage of elemental attacks including fireballs, ice spikes, lightning, and wind blades.

Under the combined attack of the three, the remnant soul's malevolent aura began to dissipate at a visible rate.

"Roar—I am a general of the Ghost Fang Clan, a warrior of the Broken Army. How dare you lowly villains disturb my eternal slumber!" The remnant soul suddenly let out a grief-stricken roar, and the remaining baleful aura on its body suddenly erupted, forming a black shockwave.

Lu Lingxi and Nalan Rongzhi were prepared and immediately withdrew, while Lan Yuan's water mirror shattered instantly.

"He's going to fight desperately!" Lu Lingxi Yao warned.

The remnant soul raised the giant axe high, chanting incantations. An ancient and desolate aura emanated from him, and his broken soul began to burn, transforming into pure energy that flowed into the giant axe.

"Oh no, he's sacrificing his remnant soul in preparation for a powerful attack!" Nalan Rongzhi's expression changed.

"We can't let him succeed!" Lu Lingxi's phoenix eyes narrowed, she held the sword with both hands, the power of chaos circulated wildly, and the Azure Dragon Sword emitted a clear and melodious sword sound. On the blade, a lifelike azure dragon pattern lit up.

"Chaos Creation Slash!"

Lu Lingxi Yao let out a delicate shout and slashed out with her sword. This sword strike combined her understanding of the laws of space with the application of chaotic power. Wherever the sword light passed, space seemed to be torn open with a tiny crack.

At the same time, Nalan Rongzhi clasped his hands together, and the purplish-black demonic energy and the spiritual power of the ten elements condensed in his palms into a rapidly spinning energy ball, which emitted a terrifying aura of destruction.

"May all lands return to peace!"

The two men's strongest attacks struck the remnant soul, which was gathering its power, almost simultaneously.

"Boom——"

A deafening roar shook the entire ancient battlefield, and a violent energy storm swept in all directions, scattering all the swirling soul shadows.
