Yuan Ming knew that the mana contained in these clones he summoned was limited, so he raised his hand to shoot out four streams of spirit light, injecting them into the four clones to sustain the mana consumption.

Although this would accelerate the mana consumption by several times, with the help of the World Tree, he could absorb a large amount of pure spiritual power from afar, without any worry about running out of mana.

The five "Yuan Ming" worked together, and indeed, the refining speed increased significantly.

However, Yuan Ming's brows remained furrowed, feeling that the speed was still not sufficient.

The next moment, he again channeled a stream of mana through the roots of the World Tree into the Forbidden Wood Pillar, attempting to refine the pillar from within.

However, his mana was not compatible with the Forbidden Wood Pillar, and this method was not effective.

"The Soul Destroying Sword is already dealt with, you just need to nurture it with mana for a while to use it. Eh, where is this? What are you doing?" Xi Hezi's figure emerged from the Xi He Tablet, his face showing surprise upon seeing Yuan Ming's actions.

Only then did Yuan Ming notice that the Xi He Tablet had been hovering beside him and had not been put away.

"Thank you for your hard work, Fellow Daoist Xi He." He expressed his gratitude and flicked his sleeve to receive the Xi He Tablet into the Shura Palace.

As for the current situation, he did not hide it from Xi Hezi and explained it simply.

"So you are fighting for the Three Realms Immortal Boat. This treasure is of immeasurable value, indeed worth contending for. However, your refining method is too poor, and your approach is incorrect. Since you have the World Tree, why use your own mana to refine this item?" Xi Hezi shook his head and said.

"Please, teach me, Fellow Daoist Xi He." Yuan Ming's eyes lit up, remembering Xi Hezi's status as an Artifact Refining Master, and hurriedly sought guidance.

"If you trust me, give me the World Tree, and I'll help you refine that Forbidden Wood Pillar." Xi Hezi said.

Yuan Ming hesitated slightly, then nodded in agreement, releasing Xi Hezi from the Shura Palace.

Xi Hezi's figure turned into a red shadow and quickly merged into Yuan Ming's Dantian, becoming one with the World Tree.

Under Xi Hezi's control, the World Tree charged towards the Forbidden Wood Pillar.

At the moment of contact, azure-gray light flickered, and the World Tree directly merged into the wood pillar.

Spirit light shimmered beneath the pillar, roots rapidly grew, and tender new shoots sprouted from the top, instantly transforming the entire pillar into a more towering World Tree.

Xi Hezi utilized the original spiritual power of the World Tree to swiftly refine the Forbidden Wood Pillar, at a speed much faster than when Yuan Ming and his four clones worked together.

Just then, a flash of white light appeared in the void turbulence, and a white sphere emerged out of thin air.

The sphere swiftly expanded a hundredfold, transforming into a house-sized white giant pearl, emanating astonishing spatial fluctuations as it hurtled towards the silver light domain.

Feeling the aura contained within, Yuan Ming's heart sank, thinking to himself, "As expected, they found me!"

In his reflections, he hurriedly controlled the silver light domain to escape into the distance.

However, the World Tree had just formed and was weak in power, moving sluggishly in the void turbulence, failing to avoid in time, and was directly hit by the white giant pearl.

With a loud crash, the silver light domain trembled violently, directly struck by the giant pearl, thrown off from the void turbulence, reappearing on the altar.

Su Wu was already standing not far away, holding one hand high, with a cluster of silver light congealing in his palm.

He suddenly swung it, and a ribbon-like silver light shot skyward, transforming into a silver giant sword stabbing into the heavens.

The blade of the silver giant sword had intense space power fluctuations, with the edges vibrating with serrated sharpness, ripping through the surrounding void even before slashing down, revealing gashes of space fissures.

"This is the Great Void Slash, a divine skill from the Creation Heaven List, specifically countering space divine power!" Xi Ying's voice sounded in Yuan Ming's ear, warning him to be cautious.

With a low shout, Su Wu swung the silver giant sword heavily down.

The void was instantly torn into a long black fissure, rapidly closing as soon as it appeared.

Yuan Ming's silver light domain, having just been knocked away from the void turbulence and not yet stabilized, was once again struck by the silver giant sword.

A sharp screech as if metal blades clashed resounded, the silver light domain was slashed with an enormous crack.

With a "boom," the silver light domain exploded, scattering into countless disordered silver glows.

The Forbidden Wood Pillar, along with Yuan Ming and his four clones, staggered into view.

Finally seeing the situation inside, Su Wu's expression turned exceedingly grim.

The Forbidden Wood Pillar, which he painstakingly set up, had turned into a lush, leafy tree in such a short time.

Fortunately, the array patterns on the trunk remained, and the mana he had infused earlier had not completely dissipated, still occupying about half of the prohibition array patterns.

After a brief moment of shock, Su Wu swiftly regained composure.

He had no time to worry about the peculiar changes to the Forbidden Wood Pillar and decisively led three clones to rejoin the refining process.

The four of them pressed their palms tightly against the tree trunk, with Su Wu at the core and Su Yingxue and the others encircling him, forming a mysterious refining formation.

They pushed their mana to the fullest, engaging in a fierce struggle for control over the Three Realms Immortal Boat with Yuan Ming.

Su Wu was initially full of confidence, thinking he could once again overtake Yuan Ming, but at the moment when his mana flowed into the Forbidden Wood Pillar, he was shocked to discover his mana, like water flowing into a blocked channel, advanced with extreme difficulty, and the refining progress was incredulously slow.

This sudden change left Su Wu off guard.

Meanwhile, on Yuan Ming's side, it was a completely different scene.

Green spirit light surged like a river, rapidly spreading over the forbidden wood pillar, refining most of the array patterns in a few breaths.

Su Wu's mana retreated step by step under Yuan Ming's assault, with no power to resist.

The situation reversed instantly, Yuan Ming was overjoyed, but dared not relax at all.

The people below stared dumbfounded at everything happening above. Since the appearance of the Silver Light Domain, they already couldn't comprehend the situation up there.

Nan Shangfeng asked, bewildered, "Master, what exactly did Wan Tianren do that even Su Wu is not his match?"

Master Tantai shook his head, silent, as he also couldn't explain it all.

"It looks like Su Wu is going to lose..." Yang Fan murmured.

The others remained silent, only able to roughly gauge the situation based on the surface events. It seemed that Yuan Ming, originally at a disadvantage, used some unknown method to turn the tables and take the upper hand.

"How could this happen?" Hei Lian and Su Yingxue's faces grew solemn.

Su Wu looked at Yuan Ming and asked in a deep voice, "What methods did you use?"

Yuan Ming did not answer his question, only his hands quickly formed seals.

His mana had spread over the entire forbidden wood pillar, now only a small corner occupied by Su Wu's mana remained.

As Yuan Ming formed seals, more than a dozen beams of green light pounced from all directions like starving wolves, fiercely gnawing at this corner.

Su Wu's mana rapidly collapsed under this ferocious attack.

Despite Su Wu's desperate resistance, it was still in vain.

Seeing his mana about to completely disperse, a trace of determination flashed in his eyes.

He suddenly raised an arm, and a hundred-yard-long silver light sword appeared above the altar.

This was indeed yet another Great Void Slash, grander in scale than before, and the spatial power fluctuations it emitted were even more terrifying.

Jie Cha saw this, and shouted, "What are you doing?"

However, Su Wu ignored Jie Cha's questioning, waved his arm, and the Great Void Slash fell like thunder, striking the center of the altar.

"Boom, boom, boom"

The sound of explosions rang out, the entire altar was split in two under this terrifying power.

Yuan Ming had been prepared, dodging away in time, thus unharmed.

But the altar's destruction caused the light on the forbidden wood pillar to disperse, and the array patterns instantly dimmed.

"Daring to destroy the altar, unforgivable!"

Jie Cha was furious, his breath surged like a storm, his hair and beard bristled, his eyes flashing with a fierce killing intent.

He raised his hand high and waved it forcefully, and then the previously silent attack surged forth once more.

This time, all the attacks gathered into thunder entwined with purple-gold and red tornadoes, crashing down like divine punishment on Su Wu, seemingly to completely engulf him.

Su Wu was already prepared, and a dense black qi emerged from him, swirling around like a demonic barrier.

No matter how dense and swift the attacks sweeping toward him, once they touched his body, they were swallowed by the black qi instantly, disappearing without a trace.

Jie Cha's face grew even darker upon seeing this, coldly saying, "Su Wu, your Heavenly Cicada Black Qi may be honed to ninety percent completion, but this is the Three Realms Flying Boat, there is no room for your recklessness!"

His words falling, he grasped into the void with his right hand, and streams of silver light flew from Yuan Ming and the people below, exactly as boarding orders.

These boarding orders plus one flying from Jie Cha's hand totaled to eight, appearing at various positions around Su Wu with a flicker.

The eight boarding orders emitted intense silver light, tightly encasing Su Wu within a giant silver light sphere.

Though the Heavenly Cicada Black Qi was fierce, under the suppression of this silver light sphere, it could not swallow anything.

Jie Cha waved his sleeves, the silver light sphere carrying Su Wu quickly merged into the void, seemingly to expel him from the Three Realms Flying Boat.

At that moment, an unexpected change arose!

A silver light suddenly shone from within Su Wu, mixed with rolling black qi, exactly from the last boarding order.

This order seemed to have been ritualized by Su Wu with some secret technique, dyed with a layer of eerie black on the surface.

Soon, Su Wu's body disassembled rapidly, transforming into a surge of black qi that quickly merged into that silver token.

The token emitted bright light, breaking free from the silver light sphere, tearing through the void.

Jie Cha saw this scene, his face sank, a trace of shock and suspicion flashing in his eyes.

"Jie Cha, I gave you some face for the sake of my master, don't think I truly fear you. Once I take control of this Immortal Boat, I will come to settle today's insult with you!" A cold voice from Su Wu came from within the silver token.

After that, the token transformed into a streak of silver light and drilled into the ground beneath the altar, disappearing without a trace in an instant.
