This Samadhi Divine Wind possessed three aspects.

The first aspect manifested as a colossal gale, its edges honed like blades, as if countless immortal swords and sabers were slashing simultaneously. Dense and omnipresent, this was known as the Wind of Myriad Blades. This Wind of Myriad Blades was terrifying enough to obscure heaven and earth, capable of unsettling gods and spirits, shattering stones and collapsing cliffs, and instantly ending a mortal life.

The second aspect was the Wind of Extreme Speed. Its primary advantage was its sheer velocity—an extraordinary quickness that afforded absolutely no time for reaction.

The third aspect was the Internal Infusion Wind, which came without shadow and vanished without a trace, easily penetrating the body to attack from within.

The Samadhi Divine Wind was even more ferocious than the Samadhi True Fire. Ordinarily, encountering even one aspect of the Samadhi Divine Wind while attempting to break through to the World Realm was a sign of terrible misfortune; yet now, all three aspects assailed simultaneously.

The rumbling thunder arrived, its roar known as the Samadhi Celestial Thunder.

The Samadhi Celestial Thunder was also divided into three aspects.

The first was Satellite Thunder—the same type Lu Yuan had blocked when ascending to the Hun Dong Realm. However, back then, Lu Yuan only had to face a single, relatively weak Satellite Thunder. Now, he had to fend off thousands of them, and these Satellites Thunders were significantly more potent than before.

The second aspect was Divine Spirit Thunder. Actual thunder gods descended, and these gods possessed martial techniques; this was no longer mere brute force, but skillful combat. Innumerable thunder gods wielding the essence of various martial paths circled Lu Yuan, engaging him with diverse martial arts.

The third was Void Divine Thunder. This shared a similar uncanny quality with the Internal Infusion Wind: it was formless and intangible, arriving silently and departing swiftly, making defense almost impossible. Before one could even react, these bolts of lightning would detonate inside the body, an utterly terrifying event.

At this point, the Samadhi Divine Wind, the Samadhi True Fire, and the Samadhi Celestial Thunder descended in unison.

There were three forms of wind, three forms of fire, and three forms of lightning.

Any single one of these nine attacks, when faced by an ordinary cultivator ascending to the World Realm, would present a lethal obstacle. Each one was a formidable trial.

But now, all nine struck together.

The convergence of these nine was extraordinary; their combined power far exceeded the sum of their individual strengths.

Setting aside the inherent multiplicative power of the 'Samadhi' aspect in the Wind, Fire, and Thunder themselves, these three elements actively complemented each other: the wind fueled the fire, the fire lent power to the wind, creating a blaze that grew uncontrollably. Woven through this tempest were the infinite strands of lightning.

Gradually, in the void, a swirling pattern of mutual detonation between Wind, Fire, and Thunder began to faintly manifest.

What a horrifying Heavenly Tribulation this was, descending from the heavens!

Indeed, many onlookers had gathered. Initially, they had followed Lu Yuan chasing the hundreds of thousands of Mechanical Myriad Poison Birds. When Lu Yuan ceased his pursuit, they were preparing to disperse, but upon seeing him attempt to break through to the World Realm, they paused to observe the outcome. That observation utterly stunned them.

This—this Heavenly Tribulation was terrifying.

Everyone present was a figure from the Lost Lands.

Due to the extremely harsh environment there, the average cultivation level in the Lost Lands was far superior to that of the Central Celestial Dynasty. Even so, the onlookers here fundamentally believed that, if nothing else, the Samadhi alone would have guaranteed their demise during their own World Realm breakthroughs. For those of the average standard in the Central Celestial Dynasty, even one aspect would have been fatal.

And now, the Samadhi True Fire, Samadhi Divine Wind, and Samadhi Celestial Thunder struck together—Wind, Fire, and Thunder lending power to one another, sweeping across the sky like the end of the world.

Under these circumstances, Light Slave Number Three Thousand and Light Slave Number Two Thousand Nine Hundred stood ready, preparing to deliver a fatal blow the instant Lu Yuan revealed any vulnerability.

Lu Yuan had already drawn his Yangwu Immortal Sword.

Lu Yuan had no intention of relying on Fleeting Dreams like Life (Fu Sheng Ruo Meng). While it was immensely powerful, constant reliance on it was unsustainable. Furthermore, Lu Yuan could clearly sense the hundreds of thousands of mechanical lifeforms lurking nearby; the moment he showed weakness, they would surely swarm him.

Very well, he would reserve Fleeting Dreams like Life for today. He would endure this Heavenly Tribulation relying purely on his swordsmanship.

The Samadhi True Fire descended first. The first aspect, the Fire of Material Burning, arrived earliest. Lu Yuan raised his Yangwu Immortal Sword and blocked the attack. His sword light cleaved outwards fiercely, driving the Fire of Material Burning back into the void with an endless barrage of flashes. Others gasped in surprise; the Fire of Material Burning was no ordinary flame, capable of igniting even immortal swords. How could Lu Yuan use his immortal sword to resist it without the blade burning? Those with keener sight, like the Eastern Ghost Emperor, immediately noticed that each contact between Lu Yuan’s sword light and the Fire of Material Burning lasted only an instant. In that fleeting moment, the flames had no time to consume the Yangwu Immortal Sword. To block it required only that momentary contact, and Lu Yuan’s precision in placement was absolutely flawless.

The second aspect, the Fire of Soul Burning, arrived simultaneously. Lu Yuan wielded his Yangwu Immortal Sword equally, relying entirely on instinct to ward off the Fire of Soul Burning. At that instant, Lu Yuan closed both eyes, trusting his feeling to guide his blade, successfully repelling the Fire of Soul Burning entirely. This demanded an innate sense for the sword and absolute faith in it.

As for the third aspect, the Fire of Karma, Lu Yuan felt no fear whatsoever. His sword light became like practiced silk; his sword moves were exquisitely precise, parrying each incoming strand.

Soon after, the Samadhi Divine Wind and Samadhi Celestial Thunder also arrived.

The first aspect of the Samadhi Divine Wind, the Wind of Myriad Blades, numbered perhaps a billion edges—deflecting them all was an almost impossible feat. However, Lu Yuan's sword light transformed into countless beams, blocking the Wind of Myriad Blades with a profoundly mystical posture, making it difficult for the billion edges to break through.

The second aspect was the Wind of Extreme Speed. Lu Yuan’s physical speed could not match the wind’s velocity, but his sword light perfectly intercepted it. No matter how the Wind of Extreme Speed shifted, Lu Yuan's sword light always managed to block it. This was achieved through perfectly judging the wind’s point of arrival, intercepting the extreme speed at the final moment.

Regarding the third aspect, the Internal Infusion Wind, which came without shadow or trace—much like the Void Divine Thunder among the Celestial Thunders—Lu Yuan faced both phenomena by merging his entire being and his sword light into one. Man became sword, sword became man; the unity of man and blade made him temporarily non-existent in the physical world, causing both the Internal Infusion Wind and the Void Divine Thunder to lose their target.

This swordsmanship was far beyond ordinary Man-Sword Unity. Standard Man-Sword Unity merely infused one's spirit, energy, and consciousness into the weapon. This was true transformation, merging the self completely with the sword—a realm of extreme difficulty.

As the Samadhi Celestial Thunder descended, Lu Yuan’s sword light acted almost without hesitation. With a single sword stroke, he shattered countless Life Star Thunders.

Against the Divine Spirit Thunder, where thunder deities manifested with various martial skills aimed at Lu Yuan, he struck out with his sword, slicing through endless ranks of thunder spirit manifestations.

When only a single aspect of Wind, Fire, or Thunder descended, it was not overwhelmingly difficult.

But now, the Samadhi Divine Wind, Samadhi True Fire, and Samadhi Celestial Thunder struck simultaneously—nine distinct currents of Wind, Fire, and Lightning assailing him at once. Faced with this multi-front assault, Lu Yuan's sword light had to be incredibly fast, impossibly swift, while simultaneously dealing with multiple foes. Furthermore, he could tolerate not a single iota of error; one slip, and the Heavenly Tribulation would strike.

This level of difficulty was nothing short of defying heaven.

All the onlookers were shaken—the Eastern Ghost Emperor, the Half-Demon Emperor, and all the great masters of the Lost Lands were astonished by Lu Yuan’s execution. Amidst such extreme speed, facing the combined onslaught of the Samadhi Divine Wind, Samadhi True Fire, and Samadhi Celestial Thunder, Lu Yuan struck at maximum velocity, yet made absolutely no mistakes. Every sword strike was perfected beyond measure, utterly flawless.

Previously, based on data received from the Central Celestial Dynasty, beings like the Eastern Ghost Emperor and the Half-Demon Emperor, while acknowledging Lu Yuan’s potential, hadn't been overly impressed, reasoning that Lu Yuan's accomplishments were in the Central Celestial Dynasty, where the average master level was far below the Lost Lands. But seeing Lu Yuan perform with such perfection now, they could only regard him with newfound respect. This youth’s future was boundless.

Meanwhile, Light Slave Number Three Thousand and Light Slave Number Two Thousand Nine Hundred kept their waiting armies in check, continuously analyzing Lu Yuan’s performance through their internal optical computers. Their analysis differed from that of others; theirs was purely computational.

"Lu Yuan's strike, flawless execution grade. Probability of successful assault: two in one thousand."

"Lu Yuan's strike, flawless execution grade. Probability of successful assault: four in one thousand."

"Lu Yuan's strike, flawless execution grade. Probability of successful assault: three in one thousand."

"Lu Yuan's strike, flawless execution grade. Probability of successful assault: one in one thousand."

"Lu Yuan's strike, flawless execution grade. Probability of successful assault: five in one thousand."

"Lu Yuan's strike, flawless execution grade. Probability of successful assault: three in one thousand." Rows of text scrolled across the optical computers. The two Light Slaves stared at the real-time analysis, equally aghast. Every sword move Lu Yuan executed was of 'flawless grade,' showing no opening, and the success rate provided by the computer remained consistently below five in one thousand.

What swordsmanship was this! What terrifying stability!

No mistakes! He executed flawless moves at the highest speed against every imaginable form of attack.

Even the optical computers of the Mechanical Civilization could not achieve this.

This truly was a normal flesh-and-blood being. Both Light Slaves were mechanical entities, accustomed to believing that they possessed superiority in areas of calculation and execution. Yet now, they discovered that in their supposed strength, the mechanical beings were inferior to this flesh-and-blood cultivator.
