Survival for All: I can deconstruct projections and synthesize everything.

In the chaotic void, Kelsu's ghostly green soul fire pulsed violently due to the arrival of Feng Yan and Yun Yin, causing his already agitated state of mind to completely lose its balance.

Leaving aside the two sixth-tier reinforcements who came to help, the key is that human; his abilities are simply bizarre and strange.

On one hand, as a sixth-tier player, he was able to intervene in the seventh-tier battlefield and even play a significant role!

Therefore, Kelsu no longer held back his strength.

The tattered black royal robe fluttered without wind, and the rules of annihilation around him surged wildly. Countless gray-black threads emerged from the depths of the void, directly drawing upon a portion of the ruins' primordial power.

"Since you insist on courting death, then I will first slay you ant-like obstacles!"

Kelsu's dry roar seemed to pierce the soul. His skeletal right hand clenched suddenly, and the ten-thousand-foot-long bone blade of annihilation condensed once again. This time, the bone blade was covered with fine black cracks, a sign of forcibly overdrawing its source.

The moment the bone blade struck, the Domain of Annihilation suddenly expanded by tens of thousands of miles.

Within the domain, all life force was instantly drained away, even light turned into a gray afterimage, and countless tiny vortexes of annihilation spun wildly, attempting to drag Lin Xiao and the Celestial Venerable into nothingness together.

"Your Excellency, the crucial weakness in his Annihilation Domain lies three thousand feet to the left rear—that's the energy interface of the Ruins' origin!"

Lin Xiao's mental fluctuations were accurately transmitted to the Heavenly Venerable's ears. The Omniscient Rule had already seen through the appearance of the Nirvana Domain and presented its energy flow diagram completely in his consciousness.

The seven-colored halo around him surged, the rule of all things returning to their source was in full operation, and countless silver spatial runes and golden purification runes intertwined, transforming into a huge net of rules that directly enveloped Kelsu.

"Spatial Anchoring, Origin Blockade!"

The moment the rune net fell, the void seemed to be nailed down, and the energy connection between Kel'Thuzad and the source of the ruins was briefly disrupted.

The speed of the Annihilation Bone Blade's strikes suddenly slowed down, and the Annihilation Vortex within the domain also paused for a moment.

In that extremely brief instant, Kelsu was once again restricted for that brief moment.

The Celestial Venerable seized this critical opportunity. The ancient tree phantom behind him surged to a height of ten thousand feet, and countless emerald green vines rushed out like swimming dragons. They were no longer simply binding, but piercing with the power of purification.

The surface of the vines was shimmering with the purifying light manifested by Lin Xiao. Wherever it passed, the gray-black power of annihilation melted away like ice and snow, and directly wrapped around Kelsu's skeletal body.

"All Spirits Corrode, Dawn of Life Breaks Through!"

With a deep shout, the Celestial Venerable channeled all the radiant light around him into the vines, and emerald energy surged wildly into the gaps in Kelsu's bones.

Fine emerald green patterns appeared on the originally indestructible skull shell, as the source of annihilation and life energy collided violently within its body, emitting continuous sounds of erosion.

Kelsu let out a painful roar, the ghostly green soul fire in his eye sockets flickering violently, and he could clearly feel the power of annihilation within his body being rapidly disintegrated.

He desperately tried to expel the life energy by activating his source, but found that Lin Xiao's network of rules was like a leech, tightly sealing off his energy nodes. Every time he activated the rules of annihilation, it would bring about an even more violent purification backlash.

"Damn sixth-order ant! What's wrong with you?!"

"Last time in the ruins..."

Kelsu stopped halfway through his sentence, and then immediately slammed his skeletal right hand into his chest, attempting to detonate a portion of the Origin of Annihilation to force back the Celestial Venerable.

But Lin Xiao had already anticipated his actions. The Omniscient Rule captured the abnormal fluctuations in the energy within his body and instantly manifested dozens of explosive rule props, which accurately landed on the energy path detonated by Kelsu.

"Boom! Boom! Boom!"

A series of intense explosions resounded within Kelsu's body, but instead of repelling the life energy, they disrupted the flow of his vital energy.

The emerald green patterns on the skeleton's body became increasingly dense, the ghostly green soul flame dimmed considerably, and its aura rippled twice in an instant.

Lin Xiao's figure flashed, and he activated the Instant Step to its maximum, arriving beside the Celestial Venerable. The light points of rules around his body converged wildly.

"Your Majesty, his annihilation essence has developed cracks. Please use the rules of life to condense the core and impact it!"

He made a grasping motion with both hands, and countless purification, penetration, and explosion rules intertwined, transforming into a slender, seven-colored light blade, which he handed directly to the Celestial Venerable.

This light blade is the ultimate embodiment of the rule of the convergence of all things, and it was specially crafted to target Kel'Thuzad's core of annihilation.

A glint flashed in the Celestial Venerable's eyes, and he accepted the light blade without hesitation, channeling all his life energy into it.

The light blade instantly grew to a length of a thousand feet, its emerald green and seven colors intertwined, radiating a breathtaking power of life.

"Judgment of All Spirits - Piercing the Source!"

The light blades that Lin Xiao projected originally wouldn't cause much damage to seventh-tier beings, no matter what he did.

But things are different after the Celestial Venerable bestows upon them the rules of life.

It quickly transformed from a light blade that could barely harm a seventh-tier opponent into one that could potentially kill a seventh-tier opponent.

The Celestial Venerable gripped the light blade tightly with both hands and stabbed it fiercely towards Kelsu's skull.

Wherever the light blade passed, the Annihilation Domain was torn apart like paper, and the gray-black energy dissipated, unable to stop this fatal blow containing dual rules.

Kelso's pupils contracted sharply, and he was instantly terrified, finally realizing that he was in dire straits.

It was too late to retreat at this moment; all they could do was gather all the remaining power of annihilation to form a thick shield of annihilation in front of them.

"The Barrier of Annihilation!"

However, this hastily formed shield was no match for the seven-colored light blade.

The light blade easily pierced through the shield and went straight into Kel'Thuzad's skull.

The purification rule instantly shattered the outer defense of its soul fire, the penetration rule tore apart the core of the annihilation source, and the explosion rule detonated within its body.

"No--!"

Kel'Thuzad let out a final, unwilling roar. His skeletal body trembled violently, and countless gray-black fragments burst forth from within him. The ghostly green soul flame instantly dimmed to its lowest point.

He could clearly feel the source rapidly dissipating; if it lingered any longer, it would be completely annihilated.

"Wood Soul Domain, Eternal Alliance, this matter... I have remembered it! When the God of Mist awakens, it will be the time of your annihilation!"

Kelsu's voice was filled with deep-seated resentment, and the remaining power of annihilation suddenly erupted, shaking off the Celestial Venerable's light blade and tearing open a spatial rift at the same time.

His skeletal body transformed into a streak of gray-black light, and without hesitation, it plunged into the crack, speeding towards the ruins.

The moment the spatial rift closed, one could still sense its lingering aura of annihilation, but it no longer posed any threat.

The Celestial Venerable did not pursue, but merely gazed at the direction where the rift closed from afar, slowly withdrawing the radiant light around him, and the illusory image of the ancient tree behind him gradually shrank.

The golden blood that had spilled from the corner of his mouth had already congealed. Although he looked somewhat tired, he couldn't hide his relief at surviving such a close call.

"Brother Lin Xiao, we owe you so much for this. Without your help, our Wood Soul Domain would probably have perished here today!"

Lin Xiao nodded slightly, the seven-colored halo around him gradually receded, and his aura fluctuated slightly.

"You're too kind, Celestial Venerable. If it weren't for your seventh-tier strength restraining me, I wouldn't have dared to personally intervene!"

The two exchanged a smile, their unspoken understanding evident.

This cross-level teamwork not only repelled a powerful seventh-level enemy, but also gave them new insights into the application of the rules.

Meanwhile, on the battlefield below, Groom and Tiamat were in dire straits.

The effects of the Dark Corrosion Origin Pill receded like a tide, causing his energy to drain away rapidly. His previously soaring combat power plummeted, leaving him at the level he had just reached when he entered the sixth rank. Moreover, his energy circulation was chaotic, with flaws everywhere at the points where the rules were connected.

On Tiamat's ten-thousand-meter-long serpentine body, newly grown dark gold scales began to fall off in large quantities, revealing the festering flesh beneath.

The Dragon Devouring Poison Mist thinned and weakened, no longer able to corrode the void. The crimson in the snake's eyes had faded considerably, replaced by deep fear.

It tried to twist its body to escape, but Feng Yan had already transformed into a golden stream of light and blocked its way.

"Trying to escape? Where did your arrogance go?"

Feng Yan's cold and arrogant voice resounded through the void. With its wingspan of a thousand meters, it spread out and golden divine fire poured down like a waterfall, instantly enveloping Tiamat's serpentine body.

The dual rules of purification and incineration contained in the divine fire also have a great effect on the power of dark erosion to some extent.

Tiamat's scales sizzled and emitted a pungent, burnt smell as they were burned by the divine fire.

"No! I don't want to die!"

Tiamat let out a mournful roar, her serpent tail thrashing wildly as she tried to break free from the divine fire's restraints.

However, after the effects of the drug wore off, its speed and power were greatly reduced, and each swing appeared slow and weak.

With a sudden flap of its wings, countless golden flame blades shot towards Tiamat like a meteor shower, landing precisely on the wounds where its scales had fallen off.

The fiery blade pierced into the flesh, and then was instantly detonated by the phoenix flames, burning away large areas of festering tissue.

Tiamat's roar grew weaker and weaker, her serpentine body convulsing and writhing in the divine fire, her dark golden blood burning into black mist that dissipated into the air.

Its dark erosion origin was completely purified by the divine fire, and its soul core gradually lost its luster.

A cold glint flashed in Feng Yan's eyes. He closed his wings, transforming them into a massive golden flaming spear. With a power that could pierce through heaven and earth, it thrust straight toward Tiamat's head.

"Phoenix - Soul-Burning Thrust!"

The flaming spear pierced Tiamat's skull without any resistance, shattering her soul core completely.

Tiamat's body stiffened abruptly, then gradually turned to ashes under the scorching of the divine fire, leaving only a few faint traces of dark corrosion, which were quickly dispelled by the divine fire of the phoenix flames.

On the other hand, Groom's situation was equally dire.

His ten-thousand-meter-long black armor was covered with cracks, and the hole in his chest reappeared, with dark energy leaking out like a deflated balloon.

The light of the Blade of Desolation dimmed, and it could no longer gather the aura of annihilation. Each swing seemed powerless.

Yun Yin's pure sea of ​​clouds had already trapped him firmly, and the purifying rosy light continuously washed over his armor like a waterfall.

Wherever the rosy light passed, the dark erosion runes on the armor shattered, the dark energy was rapidly purified, and Grum's aura grew weaker and weaker.

He tried to break free from the shackles of the sea of ​​clouds, but each impact resulted in him being entangled by the purifying light strands within the clouds, further depleting his already dwindling energy.

"You bastards of the Dark Eclipse Order, consider this a small interest payment for today!"

Yun Yin's spiritual fluctuations carried an undeniable majesty, and all the rosy light in the pure sea of ​​clouds converged, transforming into a huge, seven-colored rosy spear.

The rules of purification and spatial manipulation intertwined on the spear, radiating terrifying power as it pointed directly at the hollow hole in Grum's chest.

Grum's pupils constricted as he desperately tried to channel his remaining dark energy into a defense, but the chaotic energy flow prevented him from forming an effective shield. He could only watch helplessly as the radiant spear, carrying earth-shattering power, pierced towards his core.

"No!"

Groom let out a desperate roar, but the only response was the crisp sound of the radiant spear piercing through armor.

"Pfft—"

The seven-colored spear pierced the hollow in Grum's chest without any resistance, and the purification rules erupted instantly, completely disintegrating the dark core within his body.

Grum's body trembled violently, his black armor shattered inch by inch, and the dark energy was rapidly annihilated in the purifying glow, eventually turning into countless black specks of light that dissipated into the void.

With the fall of Grum and Tiamat, the remaining Dark Erosion Worms, Bloodthirsty Vine, and Crystal Devourer members on the battlefield suddenly lost their backbone, and their offensive collapsed instantly.

On the other hand, the warriors of Wood Soul City were in high spirits and launched a counterattack under the leadership of the city lord. Feng Yan and Yun Yin also spared some of their forces to clear out the remaining enemies.

The Dark Erosion Worm was killed after being solidified by the Wood-type rules, the Blood-Weeping Demon Vine was burned to ashes by the divine fire, and the Crystal Devourer Clan members gradually lost their ability to fight after being exposed to the purifying glow.

The sounds of battle cries and energy collisions filled the battlefield before gradually subsiding.

Half an hour later, the battlefield was finally cleared.

On the land of the Wood Soul Domain, the scorched earth and poisonous swamps are gradually being repaired by life energy, and sporadic green shoots are emerging from the soil, demonstrating the revival of life.

Although the protective array of Wood Soul City was still dim, it was no longer on the verge of collapse. The creatures inside the city emerged from their hiding places, their faces beaming with the joy of surviving a calamity.

Lin Xiao, Tianzun, Feng Yan, Yun Yin, and the City Lord of Wood Soul City gathered in the sky above Wood Soul City, exchanging smiles.

This fierce battle, which lasted for several days, finally ended in their victory.

The Heavenly Venerable of the Wood Soul Domain forcibly kept Yun Yin and Feng Yan behind, preparing to further refine the details of the alliance.

After some research, the Wood Soul Domain, the Fire Soul Domain, and the Rainbow Cloud Clan all finalized the details of the alliance between the three forces.

The next step is to find a witness.

And this so-called witness fell to Lin Xiao.

These three forces, which were originally almost unable to communicate, gradually came together and formed an alliance because of Lin Xiao's existence.

Therefore, it would be best to have Lin Xiao, the middleman, as a witness!

This answer was chosen jointly by the three of them.

In other words, from now on, any force that wants to join their small group will have to be approved by Lin Xiao.

Lin Xiao was having a great time discussing things, but the ruins were shrouded in gloom these past few days.
