High-level martial arts: Contract cashback, invincible starting from the Zerg.

Bai Fei's troops had just experienced a bloody battle with the Iron Slaughter Zerg, with more than half of the Zerg's elite forces lost. The Iron Slaughter Zerg, in particular, needed time to regroup due to the change of their new king.

If we were to go to war with a fully prepared human race now, our chances of winning would be no more than forty percent.

"Casey, contact Malone and Moon Princess immediately and have them lead all their troops to assemble on my left and right flanks to build defensive fortifications. Also, reassemble Bai Fei and the Iron Slug Zerg's ranged units and target the humans," Bai Fei said in a deep voice.

"clear."

Bai Fei slowly stood up, glanced at the wound covered by the omnipotent flesh spores, and walked out of Casey's control room in the Warbringer.

Twenty minutes later.

Humanity's vanguard has reached the edge of the battlefield.

Two hundred "Predator" combat mechs, each ten meters tall, stood in a row, their cold metal shells reflecting a blinding light in the sunlight.

The shoulder-mounted cannons of the mech flashed with eerie blue electricity, aiming at the Zerg army ahead.

In addition to combat mechs, the human army also has 30,000 human soldiers wearing power armor, as well as five powerful electromagnetic railguns.

Directly in front of the human forces, a menacing black combat mech began to approach the location where the two sides were negotiating.

...

Bai Fei sat upright at the negotiation table, her heterochromatic eyes calmly watching the black combat mechs slowly approaching from the opposite side. Her gaze was incredibly resolute.

The black combat mech came to a steady stop ten meters away from Bai Fei, its metal feet grinding against the cratered and insect-scarred ground with a dull thud.

This black combat mech is a full two meters taller than the ordinary "Predator," with a ferocious black thorn emblem engraved on its shoulder armor, and the reactor on its chest flashing a dark red light, like the heart of a lurking beast.

As the combat mech's hatch slowly slid upwards.

A man wearing custom-made dark black power armor leaped out of the cockpit.

He removed his helmet, revealing a weathered face, and glanced at Bai Fei with undisguised scrutiny and wariness.

"Wei Yuan, Deputy Commander-in-Chief of the Seventh Underground Human Fortress." The man's voice was deep and hoarse, like sandpaper rubbing against iron. "Queen Bai Fei."

Bai Fei did not get up, but only slightly raised her chin.

Although her armor was tattered, the wounds on her waist and left shoulder were still covered by omnipotent flesh spores, which glowed faintly.

But this does not diminish her innate queenly majesty.

"Commander Wei, you've brought so many people here. Are you here to avenge Queen Iron Slaughter?" Bai Fei's voice was cold and sarcastic.

Wei Yuan gave a faint, cold smile, raised his hand, and sat down opposite Bai Fei.

"That depends on what Queen Baifei thinks. Queen Tielu had an alliance with us beforehand. Her death in battle automatically puts the alliance into effect. We are here to fulfill our obligations as allies and avenge her."

"Revenge?" Bai Fei chuckled, a hint of mockery in her voice. "You really think the Iron Slaughter Insects will still consider you allies after you killed her?"

"Of course not," Wei Yuan repeated with a smile.

"We were never allies with Queen Iron Slaughter, only enemies who used each other. Now that she's dead, we should be raising a glass in celebration, but..."

He leaned forward abruptly, his gaze as sharp as a knife fixed on Bai Fei's face: "It suddenly occurred to me that you have become an even more terrifying threat than the Iron Slaughter Queen. You are about to subdue millions of Iron Slaughter insects and unify the entire surface. If we let you go today, you will lead your swarm of insects to raze our underground fortresses."

"Therefore, you only have two choices: either give up your queen status or be hit directly by our orbital cannon and turn to ashes."

Bai Fei raised an eyebrow slightly, a cold glint flashing in her heterochromatic eyes.

He leaned back lazily in the chair behind him, seemingly somewhat speechless at Wei Yuan's suggestion.

Seeing that Bai Fei remained silent, Wei Yuan immediately pointed to the human army behind him, "Thirty thousand elite soldiers, two hundred 'Predator' combat mechs, and five 'Heavenly Punishment' electromagnetic railguns. Each railgun can level a mountain in ten seconds. With just one order, the first salvo will wipe out most of your Zerg forces."

"I also requested an attack order from the underground bunker. If I don't send a safety signal in thirty minutes, all the bunker's missile silos will be activated simultaneously, targeting all the insect nests and egg bases on the surface. One hundred and twenty thermobaric missiles are enough to plow the entire surface three times over."

"At that time, the Zerg race will be completely wiped out from this planet."

As soon as he finished speaking, the five electromagnetic railguns simultaneously emitted a deep roar, and the eerie blue light from their muzzles instantly became blindingly bright.

The shoulder missile bays of all two hundred "Predator" mechs opened, revealing a dense array of missile heads.

Thirty thousand human soldiers simultaneously raised their electromagnetic rifles, the sound of the safety bolts being pulled echoing in unison, like a countdown to death.

Malone roared, dragging his giant insect crystal axe forward: "You dare!"

"Stop." Bai Fei coldly stopped him.

Malone immediately stopped in his tracks, but the murderous intent in his eyes was extremely intense.

"Commander Wei Yuan, you don't think you can threaten me like this, do you?" Bai Fei's voice wasn't loud, but it carried a chilling aura that penetrated to the bone, clearly reaching everyone's ears.

"So what if it is?" Wei Yuan met her gaze without flinching.

Bai Fei chuckled softly, slowly raising her left hand, and a shimmering white light flowed from her fingertips.

The next moment, millions of Zerg simultaneously unleashed deafening roars.

The White Flying Insect Clan raised their insectoid blades, purple insect power shimmering on the edges.

Meanwhile, the Iron Slaughter warriors brandished their sharp forelimbs, their crimson compound eyes burning with fury.

"I have already informed the entire army of the coordinates of your underground base. If you want to use your thermobaric weapons to plow the entire surface, go ahead and do it, but I can't guarantee the safety of your underground base."

"Ma Long," Bai Fei called out softly.

"Yes!" Malone responded immediately.

"See those five electromagnetic railguns?" Bai Fei pointed her finger towards the rear of the human forces. "Now, I want to turn them all into scrap metal."

"Understood!" Malone replied immediately.

Bai Fei's gaze returned to the shocked Wei Yuan, her eyes devoid of emotion, yet her tone carried a chilling killing intent.

"Wei Yuan, you should be well aware of my strength. Since you let your ally, the Iron Slaughter Queen, die at my hands, then you shouldn't be threatening your new ally."

The next moment, the crimson lightning, carrying Ma Long, soared into the sky.

Its single horn glowed with purple electricity, and it continuously spewed scorching breath from its mouth. Its pair of copper bell-like eyes were fixed on the five electromagnetic railguns behind the human forces.

"Dragon Knights, follow!"

Thousands of white and iron dragons of various shapes and sizes roared simultaneously. Some were covered in thick armor, some had sharp claws, and some could spew highly toxic acid.

Thousands of dragons took off simultaneously, like a crimson cloud that blotted out the sun, and flew rapidly towards the electromagnetic railgun position behind the human forces.

And the speed is astonishing!

Watching the thousands of Manlong troops launch a preemptive attack.

Wei Yuan's face instantly turned extremely ugly, and his breathing became rapid.

"Stop them! Stop them now!" Wei Yuan's expression changed drastically, and he roared in a hoarse voice.

He never expected that Bai Fei would actually dare to make the first move, and that her first move would be aimed directly at his most relied-upon electromagnetic railgun.

"Too late, human commander."

Bai Fei laughed coldly.

"However, I hope you can offer more useful suggestions regarding our alliance."
