Seagulls flocked and soared, their wings beating against the blue sea.
Below them lay a newly constructed, colossal, mysterious behemoth, entirely black, immense in size, its length exceeding that of the mountain ranges.
Behind this behemoth, an even taller, humanoid mecha had integrated its arms into the massive structure.
Dozens of smaller mechas were connected to the behemoth by black cables.
Gu Ya stood on the broad shoulder of You Yin, gazing forward.
Dozens of engineering mechas, utilizing quasi-energy transfer conduits, were connected to the colossal cannon, while Liang Yuwei’s “Black Ape” mecha transformed its arms into energy transmission channels, embedding them into the giant cannon.
All preparations were complete.
Now, they awaited the command to fire from the battlefield ahead.
Miles away to the southeast, a vast swarm of Black Star mechas was advancing from the blue sky behind them, like black dots coalescing into more blackness.
The airspace above the coastline was engulfed in black, the density gradually increasing, the darkness becoming so thick it obscured the blue sky.
Not far from the coastline stood the Xian Xia defenders, their white mechas proclaiming the Xian Xia faith of facing death without fear.
To defend Xian Xia, countless Xian Xia people had stepped forward, one after another, into the war.
Now, the time had finally come to counterattack!
Qiao Weiwei’s Windhouse Unit 1 mecha, along with hundreds of long-range heavy firepower mechas, were hidden within the mountains behind the coastline.
Once the colossal cannon began firing, they would ascend and unleash a saturation barrage of ammunition towards the enemy formations, ensuring not a single Black Star enemy fighter escaped!
Meanwhile, Gu Ya had found another optimal firing position.
If the tactic succeeded, he would secure the colossal cannon and await its next use.
If the colossal cannon tactic failed, he would immediately proceed to the southeastern coastline to summon the over four-hundred-meter cannon, piloting the replicated “Black Ape” mecha, and deliver another fatal blow to the enemy.
However, this tactic was a secret he had not shared with anyone.
He was an outlier in this world, and rashly displaying his abilities would plunge the entire world into panic.
That would lead to far greater trouble.
More and more black mechas converged from the rear,
The Xian Xia defenders began to show signs of fatigue, their battle line steadily retreating, shrinking to within ten kilometers of the coastline.
Everyone yearned for the command to fire from the overall command center.
Not long now!
Gu Ya’s heart suddenly stirred; soon, he would witness this earth-shattering shot!
Allowing the world to witness the might of Xian Xia!
Suddenly, a faint crackling sound came from the communicator, followed by a soft, feminine voice transmitted through wireless communication to every Xian Xia defender’s ear.
“Colossal cannon tactic is commencing. All units prepare yourselves and follow the designated tactical routes. Do not act independently!”
“Colossal Cannon Alliance, please commence final charging operations. Charging time: one minute. Countdown: sixty seconds, fifty-nine, fifty-eight, fifty-seven…”
Gu Ya looked at the colossal cannon with excitement!
The gentle sea breeze suddenly froze!
A piercing “hiss—” sound emanated from the cannon’s barrel.
Soon, thick white steam began to billow from the rear of the colossal cannon’s barrel!
As the countdown progressed, streams of white steam emerged from the rear towards the muzzle. Before long, the entire four-hundred-meter-long colossal cannon was enveloped in steam!
The “hiss—” sound of charging continued!
“Ten, nine, eight, seven, six, five…”
Gu Ya had already entered You Yin, activated the mecha, and soared into the sky. He intended to witness the colossal cannon’s firing firsthand and prepare for the subsequent second shot!
“Three, two, one!”
A powerful, soul-stirring “Fire!” rang out from the communicator!
A massive surge of white steam erupted from the muzzle!
Immediately after, fine and numerous white light beam particles gradually converged into the barrel, forming a small white ball of light at the muzzle!
Just as everyone anticipated the thunderous boom,
The muzzle suddenly went silent!
A profound stillness descended!
Gu Ya’s heart lurched. What happened? Failure?!
But in the next second, Gu Ya saw a colossal white sphere, approximately one kilometer in diameter, suddenly appear dozens of meters in front of the muzzle!
The giant sphere appeared almost instantaneously.
“Boom——————!”
A deafening roar erupted!
An unimaginably thick, bright, powerful, and unstoppable giant beam cannon shot out from the white sphere, soaring towards the enemy formations!
After firing, the giant beam cannon’s diameter continued to expand, forming a massive funnel shape in the air, reaching a diameter of five kilometers, and impacting the enemy formations with this breadth.
The blinding white light was even more intense than looking directly at the sun, rendering the entire beach a sea of white!
The entire nearshore ocean was evaporated, revealing vast stretches of dry seabed. The seabed was also churned up by the energy blast, exposing hard ocean rocks! The seabed rocks were melted by the extreme heat, forming a deep trench two kilometers wide!
Even ten kilometers away, You Yin could still feel the intense heat and the powerful hurricane!
The eardrums were continuously bombarded, rendering all sound inaudible!
The enemy had no time to escape. Even if they could, they would have been scorched by the heat to the point of immobility!
This was true for the enemy, and equally so for the defenders.
However, the pre-arranged tactic ensured that almost all defenders safely returned to the coast.
Only the hundreds of heavy mecha suicide squads, who bore the brunt of the initial damage, were vaporized in the unstoppable beam cannon.
Gu Ya was awestruck, his heart and breath momentarily stopped!
Compared to all his previous experiences, this was undoubtedly the most astonishing!
This was an offense destined to be recorded in history!
The giant beam cannon continued to fire for half a minute before its flames finally extinguished.
With a loud “Bang!” the cannon barrel disintegrated, its millions of assembled parts scattering into the sky and falling into the mountains, blanketing the entire mountain range in black.
As for Liang Yuwei’s “Black Ape” mecha, its arms had melted into glowing molten iron, dripping large drops of red liquid.
Gu Ya looked at the battlefield again. The once densely packed Black Star positions were now completely empty.
Who could have imagined that tens of thousands of enemy mechas, which had been fiercely attacking half a minute ago, would now be reduced to nothingness, vanishing from this world as if they had never existed!
High in the distant sky, the giant beam cannon pierced through the clouds, broke through the atmosphere, blasted through the space debris belt, and reached the comet fragment layer before its energy dissipated and it ceased to exist!
But the war was not over yet!!!
Gu Ya quickly maneuvered You Yin into the sky. The entire dry beach was once again claimed by the sea, and ten-meter-high waves crashed ferociously against the shore.
Behind You Yin, hundreds of heavy long-range firepower mechas simultaneously ascended, including Windhouse Unit 1.
They roared, raged, and bellowed, fueled by an immense fury to avenge their fallen comrades, shooting like arrows loosed from a bow towards the deep sea.
“Go!” Gu Ya roared, “For Xian Xia! Annihilate the Black Stars!”
Suddenly, the familiar female voice transmitted, invigorating and stirring, “Congratulations to all Xian Xia defending soldiers! The colossal cannon tactic has been a great success! Six thousand enemies eliminated! Repeat! Six thousand enemies eliminated!”
Following this, the overall command center issued a new combat order: “All operational mechas, ascend quickly, pursue the Black Stars, annihilate the Black Star flagship mecha! Drive the Black Stars completely out of the Yong Gu Zhi Lan battle zone!”
Countless mechas ascended from behind the coastline, like thousands of galloping warhorses, charging towards the depths of the sea!
Gu Ya calmed his excited emotions and glanced at his system tasks. He still needed four more extremely high-threat enemy mechas.
“No matter, I will kill more enemies!”
You Yin shot out flames, joining the general counteroffensive army, flying towards the Black Star rear positions.
…
At this moment, within the Black Star flagship mecha’s command hall, everyone turned in silence and looked in panic at General Longka Wanyou.
Longka Wanyou kicked the woman beneath him away and quickly strode to the tens of meters high holographic screen, his eyes wide with disbelief.
“My hundred thousand troops… my hundred thousand troops! My army is gone?”
As he uttered these words, everyone in the hall screamed in terror and rushed towards the exit.
The hundred or so people, not caring about each other, crowded, pushed, trampled, and screamed in fear, jamming the small exit, desperately trying to escape.
When the vast holographic screen displayed groups of white Xian Xia defending mechas in the sky once more,
Longka Wanyou’s despair was complete.
In his agitation, he had even dispatched the security forces!
At this moment, only a few thousand mechas remained around the Black Star flagship mecha!
“No, I still have soldiers! Order all available combat mechas to ascend! I will request reinforcements from Commander Xing Chen! Give me the communicator!”
Longka Wanyou shouted in anger, then turned around to see that in the vast combat command hall behind him, only one person remained, standing far away, his eyes sharp as he looked at him.
“Hahaha…” Longka Wanyou chuckled bitterly and said dejectedly, “Only you are left in the end! Orange Maple Rou Ye, you are still the best to me. I didn’t dote on you in vain!”
Even Longka Wanyou didn’t realize that as he spoke, a line of blood trickled from his lips.
The female adjutant chuckled sinisterly and calmly stated, “My real name is not Orange Maple Rou Ye. I am a Xian Xia person! On behalf of billions of Xian Xia people, I am here to avenge my compatriots who died tragically at your hands!”
Longka Wanyou was astonished. This female adjutant who had followed him for many years, this woman he treated as his own daughter, was actually a Xian Xia operative!
“Die! You filthy beast!” the female adjutant roared.
Suddenly, Longka Wanyou felt breathless. A sweet, bloody fluid surged from his stomach, and blood flowed from his nostrils, mouth, ears, and eyes, his vision gradually being stained crimson.
The female adjutant stepped forward, pulled out a pistol, aimed it at his head, and fired mercilessly. She then spat on him and quickly left the command hall.
The army crumbled like a mountain.
Having lost most of its combat strength and its supreme commander, the remaining Black Star forces had no will to fight and fled towards the Endless Sea in their mechas.
The Xian Xia defenders reached the Black Star army’s flagship mecha with almost no resistance.
They captured a large number of Black Star soldiers who had not yet escaped, as well as over a dozen young and beautiful women, victims abducted by Black Star generals.
In the waist hangar of the flagship mecha, among hundreds of Black Star prisoners, Dou Mei found the female adjutant.
They looked almost identical; if not for the difference in military uniforms and hairstyles, it would have been impossible to tell them apart.
“Let’s go, sister. You’ve been in Black Star for so long, it’s time to go home.” Dou Mei smiled and intimately linked arms with the female adjutant.
The female adjutant nodded, silently shed her black Black Star military uniform, and followed Dou Mei onto a transport mecha.
At this moment, Gu Ya was circling above the massive black flagship mecha.
Suddenly, a new mission order arrived through his communicator.
Gu Ya glanced at it, his pupils contracting.
When he looked again, he gasped!
“Xian Xia City!”
