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

After the fall of the Ironhide Queen, the Queen's Mark of the Ironhide Zerg was completely annihilated.

The spiritual connection that had been entrenched deep within the bloodline of the Iron Slaughter Insect Clan for three hundred years, an indelible mark, suddenly shattered.

Millions of Iron Slaughter Zerg, who were engaged in a frenzied battle on the battlefield, simultaneously let out extremely mournful howls.

Their movements suddenly froze, their crimson compound eyes instantly lost focus, and their previously fearless charge came to an abrupt halt. The spiritual pillar that had sustained the entire Zerg in battle had completely vanished.

In just ten seconds, the entire Iron Slaughter Zerg army transformed from a sophisticated and efficient killing machine into a disorganized mess.

Seeing that the battle was over, Bai Fei's hand holding the Blade of Daylight trembled violently. She staggered and used the sword to support herself on the ground to barely keep her balance.

The deep, bone-revealing wound on his side was torn open again by the last blow, and warm blood slowly flowed down his inner thigh, spreading out in ripples in the pool of blood at his feet.

The wound on her left shoulder also sent waves of sharp pain through her, causing her to gasp involuntarily.

"Marlon, Tsukihime...eliminate all the out-of-control Iron Slaughter individuals."

"Yes, ma'am."

"Yes, sir!"

Despite their injuries, Malone and Tsukihime immediately responded and began leading their troops to wipe out the last remaining Iron Slaughter rebels.

Bai Fei, on the other hand, forcibly suppressed the surging blood and qi within her body.

And slowly closed his eyes.

A few seconds later, a surge of spiritual power belonging to the Zerg Queen Bai Fei spread out like a tide.

A pure white light slowly rose from Bai Fei's body, like the first ray of sunlight at dawn, piercing through the blood-red mist that permeated the battlefield.

It was an aura completely different from that of the Iron Queen.

There was no violence, no madness, but a deeper, more majestic sense of oppression.

Wherever the mental energy reached, all the chaotic Iron Slaughter Insects quickly quieted down. They stopped attacking and fleeing, and began to stiffly turn their heads to look in the direction where Bai Fei was.

For the first time, an emotion other than killing appeared in those crimson compound eyes—a submission etched deep in their blood.

The Iron Slaughter Insect Clan is born with the instinct to obey the strongest.

When an old queen falls and a new, more powerful queen emerges, their instincts will drive them to make the only choice.

"roar--!"

A deafening roar suddenly rang out. A black behemoth, twice the size of an ordinary Ironslayer, stood up abruptly. It was once the Ironslayer Queen's most loyal vanguard—the Blackrock Warlord.

It abruptly shook off the White Fly insectoid hunters who tried to stop it, and with its massive forelimbs carrying a devastating force, it pounced towards White Fly.

Bai Fei didn't even open her eyes.

After absorbing the mark of the Iron Slaughter Queen, Bai Fei didn't need to go all out against this enemy who was only at the Earth Rank. She simply raised her left hand, and a bright white light blade shot out instantly.

Its movement was so fast that it was almost impossible to see.

laugh--

The Black Rock Overseer's enormous head shot skyward, while his massive body crashed heavily to the ground, twitching a few times before coming to a standstill.

Bai Fei slowly opened her eyes, a cold glint flashing in her heterochromatic pupils, her voice as icy as millennia-old ice:

"Who else disagrees?"

Bai Fei's icy voice echoed across the entire battlefield, clearly reaching the ears of every Iron Slaughter Insect.

Seeing that the Blackrock Overseer had fallen so easily, all the Iron Slaughter Insects who had lost the Queen's Mark trembled and dared not have any more thoughts of resistance.

They all lowered their proud heads, tucked their forelimbs into their chests, and made the most standard and devout gesture of submission among the Zerg.

As the last Ironhide Zerg bowed its head, Bai Fei's Queen's Mark completely covered the Ironhide Zerg's mental network.

More and more intelligence information about the Iron Slugs flooded into her mind like a tidal wave.

Ironhide Zerg hive coordinates...

The detailed organization of hundreds of thousands of troops...

Even all of the battle plans that Queen Ironhide devised before her death were flooded into Casey's database in the Warbringer.

...

When Bai Fei returned to Casey's control room in the Warbringer, Bai Fei had Casey heal her wounds while giving Casey a copy of the covenant between the Iron Queen and humanity.

"Casey, decrypt all the attachments to this document."

"Decryption progress 97%... Triple biological gene lock detected, matching residual gene fragments of the Iron Queen... Match successful."

Casey's cold, mechanical voice echoed in the control room, while dense text scrolled rapidly on the holographic projection.

Bai Fei leaned back in her chair, watching wearily as Casey analyzed the answers to the covenant.

"Decryption complete... Covenant and all annexes have been loaded."

A treaty called "Non-Aggression and Military Assistance Treaty between the Iron Slaughter Insect Clan and the Seventh Underground Human Shelter" also appeared before Bai Fei's eyes.

Subterranean humans?

Since her birth, Bai Fei only knew that there were two races on the Hunting Plane: giant beasts and insectoids, but she had never heard of a race called underground humans.

She slid the projection and read it word by word.

The core terms of the alliance are clear and unambiguous:

The Seventh Underground Human Vault acknowledges the Ironhide Zerg's absolute dominion over the surface and pledges never to launch a preemptive attack on any Ironhide Zerg territory, hive, or combat unit.

[The Iron Queen promises not to enter any of the underground human tunnel networks or vault areas, and not to attack any human bearing Vault 7 identification.]

When either party is attacked by a third party, the other party must provide military assistance.

...

"Casey, retrieve the relevant information about Vault Seven," Bai Fei said in a deep voice.

"Searching the Ironhide Zerg database... Search complete."

The projection in front of Bai Fei immediately switched to a three-dimensional underground map, with dense tunnels spreading like a spider web thousands of meters below the surface.

"The Seventh Vault is located 200 meters underground north of the Giant Beast Plains, with a current population of approximately 120 million. It possesses a complete industrial system, agricultural system, and military force, with its main weapons being electromagnetic kinetic energy weapons and geothermal energy-powered mech units."

Several blurry photos also appeared on the projection, all secretly taken by the Ironhide Zerg scouts.

In the photo, human soldiers wearing black power armor patrol a tunnel, with a huge, brightly lit underground city behind them, completely unlike the barely surviving human survivors Bai Fei remembered.

"Why did the Iron Slaughter Queen ally with them?" Bai Fei murmured, her fingertips tracing the signing date of the alliance—just a few days after Bai Fei obtained the [Dao].

"According to the analysis of the Ironhide Queen's private log, 'She seems to believe that your rise has exceeded all the expectations of the Zerg, making you the greatest threat to the Ironhide Zerg. The Underground Humans possess technological advantages that the Zerg cannot match, especially in underground warfare and long-range strikes. Allying with them could create a pincer movement in the war against you.'"

Bai Fei sneered.

"So that's how it is. She really overestimates me."

Although the Iron Queen was a shrewd strategist.

But she certainly didn't expect that her allies would become the reason for her defeat.

"Keep watching, what else is there?"

Casey's voice suddenly turned serious.

"If the Ironhide Queen dies in the war against the Whiteflies, the covenant will automatically take effect. The Seventh Underground Human Vault will fulfill its military assistance obligations and declare war on the Whiteflies until the new Ironhide Queen ascends the throne and reaffirms the covenant."

Just then, Casey's voice rang out sharply again.

"Bai Fei, I have detected a large number of human troops, 63 kilometers from our current position!"
