Purple Sky Thunder Orchid, Ultimate Thunder!

Gu Ci's gaze slowly moved through the Immortal Herb Garden before suddenly settling on a corner.

There, two strange Immortal Herbs grew side by side, with only their tips exposed above the ground as they tightly entwined around each other.

One was entirely golden, with thick leaves and vines shaped like sweet potatoes. The other was a faint gold and nearly identical in form, only slightly smaller.

"This is..."

A name suddenly surfaced in Gu Ci's mind: Sweet Potato Golden Dragon.

The name sounded somewhat ridiculous, but Huo Yuhao's records contained descriptions of this Immortal Herb.

It was not among the most supreme immortal herbs, yet it possessed an exceedingly rare trait.

It grew as conjoined twins, dependent on one another, and was most suitable for two blood-related people to consume together.

Gu Ci's eyes lit up.

"Yanyan, look over there." He pointed at the two Immortal Herbs.

"They're called Sweet Potato Golden Dragons. They grow as conjoined twins."

"If you and Grandpa Dugu each consume one, your Martial Souls will resonate with each other. Then Grandpa Dugu can help you sort out your Martial Soul, and you can in turn help Grandpa Dugu evolve."

Dugu Yan blinked. Though she did not fully understand, she still nodded vigorously. "Okay!"

Dugu Bo's expression shifted slightly at those words.

He walked over to the two Immortal Herbs, studied them carefully for a moment, and asked, "Ci'er, can this Immortal Herb truly help this old man's Martial Soul evolve?"

Gu Ci nodded. "The Sweet Potato Golden Dragon's greatest trait is that it can cause the Martial Souls of blood-related people to resonate."

"You and Yanyan are grandfather and granddaughter, connected by blood. You're perfectly suited to consume it."

"Once you condense your Soul Core, consume this Immortal Herb as well. With the power of the Soul Core, the Jade Scale Snake evolving into a Jade Scale Flood Dragon should not be a problem."

Dugu Bo took a deep breath, excitement flashing through his eyes.

The Jade Scale Flood Dragon was an absolutely terrifying existence even among top-tier Martial Souls.

He had been stuck at the Titled Douluo rank for years and had never imagined that he could still advance further within his lifetime.

"What about you?" Dugu Bo looked at Gu Ci. "Which one are you choosing?"

Gu Ci's gaze fell upon the deepest part of the Immortal Herb Garden.

There stood an Immortal Herb that was dark purple from stem to leaf. It resembled an orchid, faint Thunder Light flowing across its leaves, while not a single blade of grass grew within ten feet of it.

It was the only purely Thunder Attribute Immortal Herb in the entire garden.

"Purple Sky Thunder Orchid."

Gu Ci gave the Immortal Herb a name. "I'll take this one."

He walked up to the Immortal Herb. Under his Heavenly Eye, its energy fluctuations were extremely violent, streak after streak of Thunder Light coursing through the herb's interior.

If an ordinary person touched it rashly, they would likely be charred to ashes in an instant.

But Gu Ci was different.

He stretched out his hand, faint purple lightning dancing at his fingertips. The Thunder Attribute of his Thunder Prison Heaven-Slaying Tiger was already close to the ultimate level.

Perhaps after absorbing it, he could completely enter the Ultimate Thunder Attribute.

At that point, it might even be called the number one beast Martial Soul in the world!

The Purple Sky Thunder Orchid seemed to sense an aura from the same source. Its violent lightning power actually became gentle and wrapped itself around his fingers.

"Good fellow, you've got some spirit." Gu Ci smiled.

He carefully dug up the Purple Sky Thunder Orchid, roots and all, and placed it into a jade box.

Next, the three of them began absorbing the Immortal Herbs.

Dugu Bo stood guard nearby, protecting the two children.

Though he wanted to consume the Sweet Potato Golden Dragon immediately, he restrained the urge and waited for the two children to begin first.

Gu Ci sat cross-legged, took out the Purple Sky Thunder Orchid, and directly put it into his mouth.

The Immortal Herb melted as soon as it entered his mouth, turning into a stream of purple warmth that flowed into his abdomen.

The next second, Gu Ci's expression changed drastically.

That warm current instantly transformed into overwhelming thunder, rampaging wildly within his body.

The feeling was ten times more violent than when he had absorbed the Ten-Thousand-Year Whale Rubber!

Every bolt of lightning tore through his meridians, tempered his flesh and blood, and remolded his Martial Soul.

Roar!

Sensing its master's danger, Zi Dian instinctively tried to rush over, but Gu Ci suppressed it through their contract.

"Zi Dian, stop!"

At a time like this, no one could disturb him.

Gu Ci gritted his teeth and frantically circulated his Soul Power, guiding that violent power of thunder.

The Heavenly Eye between his brows opened wide, clearly capturing every change within his body.

Under the tempering of thunder, his meridians were reborn amid destruction, becoming broader and tougher.

His flesh was reshaped amid ruin, every inch of it containing the power of lightning.

And at the very core, the Thunder Prison Heaven-Slaying Tiger Martial Soul was undergoing an astonishing transformation.

The tiger's originally dark-purple body gradually became tinged with a faint golden color, the color that only appeared when thunder reached its ultimate state.

The golden glow in its tiger eyes grew ever more brilliant, as though it could see through all things in the world.

An unknown amount of time passed.

Gu Ci suddenly opened his eyes, and two purple bolts shot from them, exploding in midair.

He rose to his feet, lightning swirling around his body. His aura was far stronger than before.

Level 20.

After two days of cultivation, he had leaped from level 18 to level 20.

But that was not the most important part.

He raised a hand, a strand of purple lightning dancing at his fingertips. It was completely different from the lightning he had wielded before.

It was purer, more violent, as though it contained the most primal power between heaven and earth.

Ultimate Thunder!

A smile curled onto Gu Ci's lips.

His Thunder Attribute Martial Soul had finally entered the ultimate realm.

On the other side, Dugu Yan also began her absorption.

She consumed the smaller Sweet Potato Golden Dragon.

The Immortal Herb entered her stomach, and a comfortable expression appeared on her little face. Unlike Gu Ci, she did not seem to be in pain.

Yet the changes were no less significant.

The residual medicinal power from the Octagonal Mysterious Ice Grass and Infernal Delicate Apricot she had consumed before was completely activated. One cold and one hot force surged through her body, merging with the energy of the Sweet Potato Golden Dragon.

The Jade Scale Snake Martial Soul appeared behind her. Its originally pure green gradually became tinged with icy blue and fiery red.

Its body grew more slender, faint horn-like protrusions emerging from its head, while the beginnings of claws vaguely appeared beneath its belly.

Ice Fire Flood Dragon.

Dugu Yan opened her eyes and jumped up excitedly. "Brother Gu Ci, my Martial Soul changed!"

She raised her hands. A cluster of icy-blue light gathered in her left palm, while blazing flames gathered in her right.

Ice and fire coexisted harmoniously in her hands without conflicting with each other.

"Not bad. Yanyan, the quality of your Martial Soul has already surpassed the Blue Lightning Tyrant Dragon."

Beside the Ice and Fire Dual Pools, Gu Ci and Dugu Yan were becoming familiar with their new powers.

Thunder Light flickered around Gu Ci, every bolt carrying an aura of ultimate destruction.

He raised his hand in a loose grip, and a purple lightning sphere formed in his palm. Faint golden arcs danced across its surface.

That was the mark of Ultimate Thunder.

"Come, thunder."

He gave a soft shout, and the lightning sphere transformed into a streak of light that shot out, striking a massive boulder a hundred feet away.

Amid a thunderous blast, the boulder exploded into pieces. Where the rubble scattered, the lingering lightning power continued to crackle.

Zi Dian lay beside him and let out an excited low roar. It opened its mouth and swallowed several strands of dispersed lightning, the scales on its body becoming even more radiant.

Gu Ci nodded in satisfaction.

Level 20, Ultimate Thunder—there was no second starting point like this anywhere on the entire continent.

On the other side, Dugu Yan was also practicing her control over ice and fire.

The little girl moved both hands through the air, sometimes condensing a ball of icy-blue radiance and sometimes summoning a wisp of scarlet flame.

She intertwined the two powers of ice and fire, forming a spinning sphere before her. Half of it was bone-piercingly cold, while the other half blazed with scorching heat.

"Go!"
