100: Joining forces to fight the enemy, Lei Zun takes action.

Mu Gu Old Man's face was ashen, and the majestic Aura of a Five-Star Dou Zong swept through the valley like a storm.

Black mist billowed, dyeing the sky a gloomy hue.

He stared intently at Medusa, the fear in his eyes gradually receding, replaced by increasingly intense greed and killing intent.

"What a perfect ancient Bloodline Soul!"

If I can capture her and offer her to the Heavenly Venerate, it will surely be a great achievement!" Mu Gu Old Man's hoarse voice held an uncontrollable excitement.

"Little girl, with your nascent Dou Zong Soul Power, even if our attributes clash, what can you do to me?

Once this old man captures you, I will refine you daily with Netherworld Ghost Fire, and we'll see if you can maintain such arrogance!"

He abruptly formed a seal with both hands, and the black mist around him violently boiled, transforming into countless twisted chains of resentful Souls, emitting mournful wails!

These chains were even more corporeal than before, with painful human facial phantoms appearing on them, exuding a corrupting power that eroded the Soul!

"Ten Thousand Souls Devouring Heart Lock!"

Countless chains of resentful Souls, like a chaotic dance of demons, coiled towards Medusa and Li Ao from all directions, sealing off all space for evasion!

Before the chains even arrived, the wails and resentment that struck directly at the Soul had already assaulted them, attempting to disturb their minds.

Medusa's purple eyes were icy cold, and she let out a snort, as a brilliant seven-colored radiance erupted around her.

She lightly waved her jade hand, and a majestic Soul Power surged out, not transforming into a physical attack, but rather condensing around her and Li Ao into a giant, slowly rotating seven-colored lotus phantom!

The lotus petals unfurled, exuding an Aura of sanctity, purification, and guardianship, completely blocking all the incoming wails of resentful Souls and corrosive power!

The chains of resentful Souls collided with the seven-colored light barrier, emitting "hissing" sounds, and black smoke billowed, unable to advance even an inch!

"Seven-Colored Guardian Barrier!" Mu Gu Old Man's pupils constricted.

This Soul defense method was unheard of!

"Is that all your attack amounts to?" Medusa stood at the heart of the lotus, her voice clear and cold, tinged with disdain.

Although her Soul Realm was lower than his, with her Soul reshaped by the Origin of the seven-colored spirit nurturing lotus and the blessing of the Seven-Colored Sky Swallowing Python Bloodline, the quality of her Soul Power was extremely high, and its suppressive effect on Netherworld power far exceeded imagination!

"Arrogant!" Mu Gu Old Man was furious, and the Aura of a Five-Star Dou Zong completely erupted.

He opened his mouth and spat out a mouthful of vital blood, which merged into the myriad chains.

The chains of resentful Souls instantly turned crimson, their power skyrocketing, like giant blood-colored pythons, frantically impacting the seven-colored barrier, causing the light curtain to violently shake!

"Your Majesty, let's join forces to defeat the enemy!" Li Ao's eyes were sharp, realizing that although Medusa could defend, prolonged defense would inevitably lead to defeat.

Though he had consumed a considerable amount of Qi, now was certainly not the time to stand by.

He took a step forward, and the dark golden Qi and Blood surged again, his Black Iron Hegemon Body pushed to its limit!

At the same time, he pointed his fingers like a blade, and the restrained Qi flow of Return to Stillness lingered at his fingertips.

"Annihilation, Soul Sever!"

A silver-gray thread, even more condensed and subtle than before, silently slashed out!

This attack was not directed at the blood-colored chains, but rather directly pierced through the Void Realm, aiming at the Soul connection between Mu Gu Old Man and those chains!

"Hmm?!" Mu Gu Old Man's mind was greatly shaken, feeling his connection with the Ten Thousand Souls Devouring Heart Lock suddenly become obscure, as if forcibly severed by an invisible force!

Those violent blood-colored chains immediately paused, their power greatly diminished!

"Good opportunity!" Medusa's eyes flashed, seizing this fleeting chance!

She formed a seal with both hands, and the seven-colored rune on her forehead glowed brightly, her Soul Power pouring out without reservation!

"Sky Swallowing Secret Art — Seven-Colored Soul Annihilation Light!"

A seven-colored light pillar, far thicker and several times more condensed than before, erupted from her palm like a divine spear that split heaven and earth!

Wherever the light pillar passed, those stagnant blood-colored chains, as if encountering their nemesis, disintegrated and melted, purified into the most fundamental Soul particles!

The seven-colored light pillar tore through layers of obstacles, carrying the glorious Divine Might that purified all evil, directly piercing towards Mu Gu Old Man's chest!

"Bastard!" Mu Gu Old Man was both shocked and enraged.

He hadn't expected Li Ao's bizarre Rule power to interfere with his Soul control, nor had he expected Medusa's counterattack to be so fierce and overbearing!

In a hurry, he could only frantically condense the remaining black mist and Netherworld Dou Qi in front of his chest, forming a thick skull shield!

"Boom —!!!"

The Seven-Colored Soul Annihilation Light fiercely struck the skull shield!

There was no stalemate, only purification and annihilation like dry weeds and rotten wood!

The skull shield only lasted for a breath before it exploded!

Mu Gu Old Man was hit hard, his chest scorched black, as if burned by a sacred flame, and a mouthful of blood mixed with black Qi spurted out, his Aura instantly weakening considerably!

He staggered back, looking at Li Ao and Medusa standing side by side, his eyes finally revealing horror and a hint of fear!

The cooperation of these two, one interfering and weakening with a strange Rule, the other launching the main attack with a supreme Soul Divine Ability, and their attributes perfectly suppressing his Netherworld power!

If the battle continued, he, a Five-Star Dou Zong, might truly suffer an unexpected defeat!

"Good, good, good! I didn't expect this Venerate to be pushed to such a degree by you two juniors today!" Mu Gu Old Man's eyes were filled with extreme malice.

"But do you think this is the end?

This area within a hundred li has long been set up with the 'Nine Nether Soul Locking Formation' by this Venerate!

Today, you have no escape!"

He suddenly crushed a black token!

"Buzz —!"

Around the entire valley, nine thick black light pillars shot up into the sky, intertwining in the air to form a giant black spider web that covered heaven and earth!

On the spider web, countless resentful Souls struggled and roared, emitting terrifying fluctuations that imprisoned space and sealed the Soul!

Within the Formation, Netherworld Qi flourished, greatly suppressing the power of Li Ao and Medusa, while Mu Gu Old Man's Aura recovered considerably under the Formation's blessing!

"In this Venerate's Formation, slowly enjoy the pain of your Souls being stripped away! Hehehe!" Mu Gu Old Man stood at the core of the Formation, letting out a triumphant strange laugh, and began to activate the Formation's power.

Countless black Soul tentacles extended from the spider web, grabbing towards the two.

Li Ao and Medusa stood back to back, their expressions solemn.

This Nine Nether Soul Locking Formation was of an extremely high grade, and with their current state, forcefully breaking it would be extremely difficult.

"It seems we can only resort to our last resort..." Li Ao's eyes sharpened, and he was about to, regardless of the consumption, forcefully activate a deeper level of Annihilation Rule, even if it meant damaging his Soul, he would break this Formation.

Medusa also clenched her jade hand, and seven-colored light condensed in her palm, preparing to unleash a forbidden Soul skill that would consume her Origin.

Just at this critical moment —

"Hmph! How dare the demons and monsters of the Hall of Souls set up such a filthy Formation within my Pill Tower Soul Realm?!"

A furious roar, like Nine Heavens thunder, suddenly resounded through heaven and earth!

The majestic righteousness and terrifying pressure contained in the voice instantly dispersed the wails of the myriad resentful Souls!

A dazzling silver lightning bolt, like a giant Dragon tearing through the sky, shot out from the direction of the Pill Tower's core in the distance, striking fiercely at the giant black spider web with an irresistible force!

"Crack!!!"

Like shattering glass, the seemingly indestructible Nine Nether Soul Locking Formation, under this magnificent lightning, failed to hold for even a breath before it shattered inch by inch, transforming into scattered black Qi and dissipating!

The lightning bolt's momentum did not diminish, and it directly struck Mu Gu Old Man at the core of the Formation!

"Tian Leizi?! How could you..." Mu Gu Old Man let out an extremely terrified shriek.

Facing this terrifying lightning imbued with the righteousness of heaven and earth, the Netherworld Dou Qi in his body was suppressed to the extreme!

He frantically burned his vital blood, conjuring several life-saving Soul artifacts to block in front of him!

"Boom —!!!"

Thunder roared, and light swallowed everything!

When the lightning dissipated, only a huge scorched crater remained, along with a few shattered fragments of Soul artifacts.

Mu Gu Old Man's figure had disappeared, leaving only a wisp of rapidly dissipating black blood mist in the air and a distant roar full of malice:

"Tian Leizi! Pill Tower! And you two juniors! The Hall of Souls will never let this rest —!"

The voice faded into the distance, clearly indicating that Mu Gu Old Man had, at the last moment, used a secret technique to escape at all costs.

The sky regained its clarity, and sunlight streamed down.

A majestic figure enveloped in lightning, like a thunder god descending to the world, slowly descended from the sky.

It was none other than the Pill Tower's titan — Tian Leizi!

His gaze was like lightning, sweeping over Li Ao and Medusa below, lingering for a moment on Medusa's corporeal seven-colored Soul body, a hint of surprise flashing in his eyes, then he looked at Li Ao and said in a deep voice:

"Lad, you're quite skilled at getting into trouble.

You even attracted that old ghost Mu Gu."

Li Ao reined in his Aura and bowed respectfully to Senior Tian Leizi: "Thank you, Senior Tian Leizi, for your timely rescue."

Medusa also nodded slightly in acknowledgment, her purple eyes still carrying the arrogance of a Queen, but she also showed basic respect to this Peak Dou Zun expert whose strength far surpassed hers.

Tian Leizi waved his hand, his gaze sweeping towards the direction where Mu Gu Old Man disappeared, his brows slightly furrowed: "Although Mu Gu retreated, the Hall of Souls will not give up so easily.

This place is no longer safe; come with this old man to the Pill Tower's core region."

He swept his sleeve, and a gentle yet irresistible force enveloped Li Ao and Medusa.

The three transformed into lightning and instantly vanished from their original spot.

The next moment, they appeared inside a giant, ancient tower that exuded a rich medicinal fragrance and vast Soul fluctuations.

Elder Xuan Yi was already waiting there, and when she saw Tian Leizi bring back Li Ao and a corporeal, powerful, unfamiliar Soul body, a look of surprise also appeared in her eyes.

"The Guild Master is currently in seclusion, deducing an important matter, and cannot be seen for now." Tian Leizi looked at Li Ao, his tone serious, "Regarding the cooperation, Xuan Yi and I have already tentatively agreed.

The Pill Tower can establish a deeper alliance with you, and... this friend behind you."

His gaze fell on Medusa again, with a hint of meaning.

Li Ao's heart stirred, knowing that this was because Medusa's demonstrated potential and value, as well as their combined performance against the Hall of Souls Elder, had made the Pill Tower determined.

A new alliance was thus established.

And the counterattack against the Hall of Souls was about to open a new prelude.
