"It seems this Netherworld Stone is quite precious. Absorbing thirteen Netherworld Stones only slightly strengthened the Netherworld Pattern mark, still far from advancing to the realm of a Second Seal Netherworld Pattern Master."

Lin Mo took a deep breath and muttered to himself.

His words would make the people of the Netherworld Sect spit blood. The cultivation of Netherworld Patterns is extremely difficult, and if one could break through with just a dozen pieces of Netherworld Stone, the Netherworld Pattern Master would be too cheap.

Although he did not advance to the realm of a Second Seal Netherworld Pattern Master, absorbing thirteen Netherworld Stones made the Netherworld Pattern Fire Seal slightly stronger, and the Netherworld Pattern Power within him significantly increased.

"I wonder how powerful this Dark Phoenix Seal is?"

Lin Mo's lips curled into a faint smile. During the three days of absorbing the Netherworld Stones, he also split a strand of his soul to comprehend the Dark Phoenix Seal. Now, he gradually grasped some methods of using the Dark Phoenix Seal and couldn't wait to try it.

Currently, the only techniques Lin Mo could rely on besides the Heavenly Reversal Nine Swords are the Purple Shadow Holy Fist and Sealing Skill. As for the techniques and martial arts cultivated in his past life, they are of little use at this realm. Besides, no one would dislike having more techniques and spells.

Dark Phoenix Seal, low-level offensive spell.

Netherworld Pattern Techniques are divided into three levels: low-level, middle-level, and high-level. Although it's just a low-level Netherworld Pattern Technique, its power is multiple times stronger than ordinary spells, as it is a technique left from the Netherworld Era, incomparable to today's spells.

"Mr. Lin, you're awake." At the cave entrance, Zhou Xinyue opened her eyes, stopped cultivating, and stood up.

"Yes, the Netherworld Stone has been absorbed. I'm thinking of testing the power of the Netherworld Pattern Technique." Lin Mo nodded, looked at Zhou Xinyue, and smiled, "Rest assured, since I promised to help avenge your master, I will certainly not forget. After handling things here, we'll seek revenge from the Five Primus Sect."

"Alright, I will certainly make those people from the Five Primus Sect pay with blood." Zhou Xinyue clenched her fists, a chill flashing through her beautiful eyes.

Lin Mo smiled and said no more, directly leaping out of the cave. Snow and wind filled the sky, ice grains spinning in the hurricane, like ice blades wildly rampaging over the Ice Plateau, leaving crisscross marks on the Ice Plateau.

Ahead, a roughly thousand-meter ice peak stood amidst the snow mountains. Although a thousand-meter ice peak is only considered a small mountain on the Ice Plateau, some vast ice peaks are tens of thousands of kilometers high and seemingly endless. 𝗳𝚛𝗲𝕖𝕨𝕖𝗯𝚗𝚘𝕧𝕖𝗹.𝗰𝗼𝕞

"Dark Phoenix Seal!"

A black silhouette stood before the ice peak, exuding extremely strong Primordial Power fluctuations—this silhouette was none other than Lin Mo, who had exited the cave.

Gazing at the steep ice peak before him, Lin Mo's eyes sparkled with extraordinary brilliance. He slowly stretched out his palms, as the dark serpent and Netherworld Pattern Fire on his back emanated a ghostly purple aura, threads of purple energy gathering on his palms, becoming increasingly dense.

As Netherworld Power gathered, both of Lin Mo's palms were enveloped in dense purple aura. Around the world, thunderous sounds boomed as True Yuan and Spiritual Energy within a radius of tens of thousands of miles crazily converged toward the sky.

"Destroy heaven and earth, Dark Phoenix Seal!" Lin Mo shouted in a low voice, a gigantic vortex appeared in the sky, sucking in Spiritual Energy from a radius of tens of thousands of miles, nearly draining it dry in an instant.

Meanwhile, the vortex rapidly expanded upon devouring countless Spiritual Energy, as if the sky had been pierced, emitting endless suppression and oppressive power, seemingly intent on destroying the entire Ice Plateau.

"Go!"

Lin Mo's eyes burst with brilliance, his handprint transforming, as a dazzling purple light beam shot out from his palm, like a purple dragon piercing hell, rushing to the Heavenly Court, and faintly a Dragon Roar echoed across the Ice Plateau.

Rumble!

The purple light beam pierced through heavenly mechanisms, shooting straight into the vortex in the sky. The vortex devoured the power within the purple beam, dyeing the entire vortex in eerie purple, like purple thunderclouds concentrated in the sky.

"Dark Phoenix Seal!" Lin Mo's sword eyebrows furrowed, he shouted explosively, flipping his palms and pressing down.

Clang!

Above the sky, suddenly a Phoenix cry emanated from the purple vortex, reverberating through the heavens, and then a purple phoenix, flapping its long wings, flew out of the vortex, an ancient aura instantly pervading the air. The purple phoenix isn't a real phoenix, but condensed from countless energies, yet as tangible as a real one.

Virtually a suppression spread across the heavens and earth, and then this dark purple phoenix let out a clear Phoenix cry, after circling the sky once, fiercely collided toward that ice peak, leaving a trail like purple flames in the sky, like a purple ribbon spanning the sky.

Zhou Xinyue widened her beautiful eyes, her face full of astonishment, she had never seen anyone perform such a mighty spell.

When the purple phoenix collided with the ice peak, circles of purple ripples burst out, spreading outward. The purple ripples poured down like a flood, those ice peaks and snow mountains seemingly fragile as tofu, crumbling into powder under the spread of the purple ripples.

Rumbling sounds rang ceaselessly, even Lin Mo revealed a trace of excitement.

This level of Netherworld Technique is immensely powerful, the surrounding area is in shambles, resembling the aftermath of a battle between two Star System Level Experts.

However, although the spell is powerful, it requires time to accumulate energy.

"Netherworld Technique is so powerful?" Lin Mo secretly marveled, if Li Ling had obtained the 'Dark Phoenix Seal' and cultivated it successfully, at that time if he had unleashed this move, he might have severely injured me directly.

Even Lin Mo was puzzled, after sealing the Alien Demon, it lost all spiritual wisdom and life aura, yet a dark snake-like imprint appeared on his back, this mysterious imprint endowed him with an innate ability to sense Netherworld Patterns.

Whether cultivating Netherworld Techniques or sensing Netherworld Pattern Power, he found it natural and effortless.

"Congratulations, Mr. Lin, for mastering such a formidable spell." Zhou Xinyue flew to Lin Mo's side, smiling radiantly.

"I didn't expect the Netherworld Pattern Technique to be so mighty, wonder what kind of astonishing abilities those powerful beings of the Netherworld Era possessed." Lin Mo inwardly reflected.

The current Netherworld Pattern Techniques are incomplete remnants, if during the Netherworld Era when the world was filled with Netherworld Pattern Power, the techniques cast by powerful Netherworld Pattern Masters might easily destroy a star, or even a star system.

"After waiting a few days, finally someone has come looking." Suddenly, Lin Mo clenched his fists, his lips curling into a faint smile.

"Did the people from the Netherworld Sect chase us?" Zhou Xinyue frowned her exquisite eyebrows, her charming face showing a serious expression.
