Here is the English translation for Chapter 150, formatted with clean syntax, polished grammar, and an engaging narrative style tailored for Western fantasy readers, maintaining proper character consistency (including Barsha as a female squad leader):

150. Manifestation of a Supreme Energy

Regulating her breathing, Barsha touched down on the scorched soil, her internal core noticeably depleted. Engaging high-ranking dark generals at maximum capacity required immense energy expenditure. Warrior Jiro's foresight in subjecting the Sky Squad to a hellish training regimen had proven entirely justified.

Without that grueling conditioning, the young guardians would never have built the physical capacity or spiritual stamina required to hold the line against the Demon Lord's dark army.

Looking around at her comrades, Barsha saw faces lined with exhaustion, yet glowing with triumphant relief. Silver and Bronze had been completely eradicated by their combined efforts. Barsha offered a proud smile to Nanji, Yara, Samuel, Rosa, and Binto. The young operatives could hardly believe they had fought a high-tier dark army detachment and emerged victorious.

Their minds flashed back to the brutal initiation trials when they first joined the vanguard. Back then, their parameters had been a tiny fraction of their current strength. Having pushed their cultivation to an elite peak, they felt a profound sense of pride in serving as the Sky Squad.

Lao and Dasatama approached the group.

Dasatama turned to acknowledge the twenty-five elite masters who had accompanied him from central command. He expressed his sincere gratitude to the veteran warriors, praising their loyalty and combat excellence.

The twenty-five alliance veterans, in turn, looked upon the young Sky Squad with unfeigned admiration. Despite their youth, these operatives commanded tactical parameters capable of safeguarding the peace of all five continents.

The continental advisors had made the right decision in establishing a specialized vanguard force. Under Warrior Jiro's rigorous instruction—personally entrusted by Dasatama to oversee their conditioning—the investment had yielded extraordinary results.

With the Sky Squad executing their duties so flawlessly, command could breathe easier. From this day forward, these young guardians would stand as the beacon of hope for a new generation.

The twenty-five peak Rank 8 warriors stood at attention, offering a formal military salute to the Sky Squad. Recognizing the tribute, the young operatives returned the bow of respect to their alliance allies.

With the sector secured, the joint task force moved to assess the remaining flanks. Though the forest was vast, they held complete faith that the other Sky Squad units scattered across the region were achieving similar victories against the dark army.

Having witnessed Leader Barsha's assassin mastery and Lao's breathtaking wind manipulation firsthand, they knew the remaining operatives possessed the strength to turn the tide in their respective sectors.

Activating his communication artifact, Dasatama established contact with Commander Yarko. Yarko reported that his division had successfully neutralized the dark army in his sector, confirming the total elimination of another Gatekeeper—Denta.

The joint task forces agreed to converge at a designated rally point on the northern perimeter of the forest. Orders were dispatched to every military division operating inside the Tulisma Forest to fall back to the same coordinates.

"Let us move swiftly; the others are awaiting our arrival," Dasatama instructed the combined force.

Nodding in agreement, the operatives fell into formation behind the continental leader. Moving at an elevated pace, they surged forward, eager to consolidate their forces and cross-reference intelligence regarding the grand battle.

Owing to the vast expanse of the woodland, information regarding isolated clashes had been fragmented. Reports confirmed that all Four Gates had mobilized inside the Tulisma Forest, leading heavy dark detachments into battle.

Dasatama needed to compile a complete after-action report to prepare for the coming global invasion rumored to be launched by the dark army.

The joint force made its way toward the northernmost reach of the Tulisma Forest—a wide, open coastal plain bordering the sea. The open terrain offered a far more suitable staging ground than the treacherous passes of the Alpine Mountains or the rocky cliffs of the Baikra Waterfall.

Leaping across the high branches at full velocity, they covered ground at remarkable speed. Traversing the forest via canopy-gliding allowed them to cross the region in a matter of hours, whereas traveling on foot or horseback would have taken days.

Two hours later, several Sky Squad units and military task forces reached the northern perimeter of the forest, reuniting with parties of independent cultivators who had evacuated early.

Just as Barsha's team and Dasatama's contingent were about to clear the tree line, a violent seismic tremor rippled through the earth. The ground shuddered beneath their boots, shaking the ancient trees. Pushing through the final stretch, they broke out of the canopy just as the tremors intensified, accompanied by thunderous atmospheric cracks in the sky above.

Another storm?

Reaching the edge of the woodland, Dasatama's group joined the main body of troops already assembled along the coastal plain. The seismic shaking showed no signs of stopping. On a high bluff overlooking the ocean, jagged streaks of celestial lightning rained down in a continuous, deafening barrage.

CRACK! CRACK! BOOM! BOOM!

The earth shuddered violently with every strike, the vibrations felt by every warrior present. Barsha and Dasatama's units merged with the main assembly along the shore—the final contingents to exit the forest. Yet their attention was instantly drawn to the oceanic bluff, where blinding bolts of lightning struck the peak in endless succession.

CRACK! BOOM!

The lightning barrage showed no sign of abating. Whenever a bolt struck the summit, a seismic shockwave rippled across the terrain. The continuous bombardment forced the assembled martial artists to deploy internal aura shields to buffer against the acoustic shockwaves.

What kind of phenomenon was this?

A gale-force tempest erupted over the coastal plain, kicking up clouds of dust and sea sand that obscured their vision.

Atop the distant bluff, the lightning strikes grew increasingly violent. As branching bolts struck the stone peak, the earth shook repeatedly, preventing the ground from settling before the next impact landed.

Every grandmaster present could sense an extraordinary, high-density energy radiating from the summit. The aura was so overwhelming that several junior cultivators panicked, assuming the Demon Lord himself was descending upon the field.

"Lord Demon Shura has arrived!" a terrified cultivator blurted out, unable to contain his dread as the crushing aura pressed down upon them.

Aji, however, remained perfectly calm. He could feel the immense pressure emanating from the bluff, yet he knew with absolute certainty that it was not Shura's aura. The Demon Lord's true presence was vastly more sinister than the energy shaking the earth beneath their boots. Studying the lightning strikes atop the bluff, Aji realized the phenomenon was an emerging energy source, not a living entity.

Could it be...?

CRACK! BOOM!

The celestial lightning continued its localized bombardment until a breathtaking sight unfolded before the assembled crowd. Pushing their senses through the howling dust storm, the martial artists sharpened their vision with internal aura.

A final, massive bolt of lightning shattered the stone peak, blasting boulder fragments into the air. The blinding glare forced many to shield their eyes.

As the blinding light settled, the lightning strikes ceased abruptly. The gale-force wind died down, and the flickering atmospheric sparks faded into silence.

Directly where the lightning had concentrated, a radiant sphere of incandescent light hovered above the ruined peak, shining as brightly as a fallen star in the night sky.

The glowing sphere radiated an unfathomable volume of celestial energy. Though its precise form remained obscured by the glare, its presence was unmistakable. The independent cultivators, alliance leaders, military commanders, and Sky Squad members all reached the exact same conclusion simultaneously.

It was the fourth celestial artifact prophesied across the five continents: the Moon Flower.

Meanwhile, inside the subterranean stronghold...

Lord Demon Shura stepped out of his private chamber, entering the grand assembly hall where the Four Gates customarily gathered to guard his retreat. Nesia stood at the center of the hall alongside a division of dark operatives.

As the Demon Lord approached, a wave of suffocating dark pressure washed over the room. The dark operatives dropped to one knee, bowing their heads in absolute submission. Nesia was already kneeling at the forefront.

For ordinary dark soldiers, beholding the Demon Lord in person was an unprecedented event; previously, only the Five Gates were permitted in his presence. The absolute majesty and terrifying malice emanating from Shura's frame paralyzed the room in awe.

Shura ascended the dais, resting his palm on the armrest of his grand dark throne.

Suppressing her anxiety, Nesia raised her voice to inquire, "My Lord! How shall we proceed regarding the Moon Flower? Intelligence confirms its official manifestation!"

Nesia reported the news promptly. Had Shura not engineered the energy collisions inside the Tulisma Forest specifically to force the celestial artifact to bloom?

She awaited her sovereign's directive.

A subtle smirk touched Shura's lips. He could feel the distant resonance of the fourth celestial artifact blooming on the northern coast. Yet, rather than dispatching a retrieval strike, the Demon Lord remained remarkably unbothered.

"Leave it be, Nesia."

Nesia dared not question his command, though confusion lingered in her mind. Why would Lord Demon Shura take no action after orchestrating a continent-wide sacrifice to summon the Moon Flower?

"Contain your impatience, Nesia," Shura chuckled, his tone laced with dark amusement. "Let the mortals fight amongst themselves. Human nature is governed by insatiable greed—you shall see soon enough! Bwahahaha!"

Shura's thunderous laughter echoed through the vaulted cavern. He understood the intrinsic flaws of human ambition better than anyone. He had foresaw it all: the moment a divine artifact appeared, the righteous alliance would fracture as greed consumed their hearts. They would turn their blades on one another in a desperate bid for supreme power.

It would prove to be a magnificent spectacle.
