Immediately, the Black Spine Bugs became agitated, flapping their wings to take flight. But in the next moment, the Black Steel mech raised its alloy spear and thrust it into the base of the bug's wing.

The Black Spine Bug, having just taken off, let out a mournful cry and plummeted from the sky, crashing heavily to the ground.

Then, Su Mo controlled the Black Steel mech, rotating the alloy spear and plunging it into the weakest point of the bug's skull.

*Crack!*

Viscous fluid splattered everywhere.

The Type III Black Spine Bug's massive body convulsed violently, struggling to rise with obvious reluctance.

However, its biological functions rapidly declined, and its eyes slowly closed.

It was finally dead.

An Li and the others watched this scene with expressions of disbelief.

A Type III Black Spine Bug had just been taken down like that?

An Li shook his head, certain that it wasn't Lu Ou piloting the mech.

Wen Luosi, observing the scene, couldn't help but praise Su Mo inwardly. Su Mo's combat skills never failed to amaze.

At that moment, the Black Steel mech sped over and stopped in front of the group. The cockpit opened, and Su Mo jumped out.

"Su Mo, it's you!"

An Li's eyes widened in astonishment.

Su Mo, hearing An Li's surprised voice, smiled and waved.

"Brother Su Mo, you're too strong."

Mi Na's eyes were filled with admiration.

"You're simply amazing," Lu Ou said excitedly.

"It was nothing," Su Mo replied casually.

"Listen everyone, it's not safe here. We'll escort you to a nearby shelter," An Li said.

"You guys go," Su Mo said after a moment of thought.

"Brother Su Mo, aren't you coming with us to the shelter?" Mi Na asked, slightly surprised.

"No, it should be fine from here on out. We should head back too. Captain An Li, I'll leave the rest to you," Su Mo said, shaking his head.

"Don't worry, Mi Na is one of our team members, we'll make sure she's safe. And thank you," An Li said, bowing to Su Mo.

"No need to thank me. Wen Luosi and I will be leaving then," Su Mo said, waving to the group.

Xiao Mila and the other children looked reluctant, their eyes red as they waved goodbye to Su Mo.

Then, Su Mo and Wen Luosi ran towards the center of the most intense fighting.

------------------------------------

On a high platform in the central building, Si Bo De and Bei Luo were watching the fierce battle unfold.

Type IV Bio-Mech: Blade of Shadows and Type IV Bio-Mech: Red Eye charged towards the Black Spine Bug King once more!

The sharp blades and super-alloy spears slammed against its AT Field!

*Bang!*

The entire AT Field vibrated violently, but it showed no signs of breaking.

In response, the Black Spine Bug King opened its mouth, charging a ball of violent red energy, and fired it.

The two bio-mechs dodged swiftly!

The next moment, the violent energy exploded in the space between the two mechs!

The massive shockwave sent them flying.

Then, the Black Spine Bug King flew towards the south without looking back.

The two bio-mechs that had been blasted away simultaneously opened their abdominal launch bays, firing two deep-red missiles. At the same time, the surrounding auxiliary combat mechs unleashed a dense barrage of missiles. In an instant, an incredibly dense wave of projectiles struck the Black Spine Bug King, creating an explosion in mid-air like a small sun.

The shockwave spread violently!

However, when the explosion subsided, the Black Spine Bug King was still flying in the air, its AT Field remaining strong.

Of course, it wasn't entirely without effect; at least it had been stopped.

The two bio-mechs once again rushed in front of the Black Spine Bug King, blocking its path.

The Black Spine Bug King was instantly enraged, and lunged at them.

The two bio-mechs simultaneously deployed ET Fields, and the three entities collided repeatedly, engaging in fierce combat.

However, upon closer inspection, it was clear that the Black Spine Bug King held a significant advantage, almost completely overpowering the two bio-mechs.

As for the battle against the Black Spine Bug Queen, things weren't much better. The Type IV Bio-Mech: Gray Shell and Type IV Bio-Mech: Floating Wing Envoys were also being pushed back.

Their attacks were unable to break through the Black Spine Bug Queen's AT Field in the short term.

Bei Luo watched the stalemate, her expression growing somber.

A 4-on-2 fight, yet they were struggling so much.

Si Bo De watched the scene without any change in expression; it was all within his expectations.

The only thing he found a little strange was that the two Type IV Bugs seemed to be acting oddly. Normally, invading monsters would prioritize eliminating the enemies blocking their path.

But these two monsters seemed to be trying their best to shake off the intercepting forces, and kept trying to rush towards the southern region.

Si Bo De keenly sensed the anomaly. He had a feeling that this attack was not so simple.

Of course, Si Bo De wasn't foolish enough to ask Bei Luo about it. Everyone had their secrets.

Even the closest of friends couldn't easily ask about such things, as it could easily lead to a falling out.

Not to mention that their relationship wasn't even close enough to be called a friendship.

At that moment, the sound of footsteps came from the side. Si Bo De glanced over and saw Su Mo and Wen Luosi, led by an Yanas officer, also approaching.

The two of them walked straight towards Si Bo De and stood behind him, knowing their place.

Si Bo De didn't say a word throughout, simply watching the battle in the distance, as if Su Mo and Wen Luosi's return was the most normal thing in the world.

At that moment, Bei Luo raised her left hand and tapped a few times on her wristband, sending a command.

Then, the ground in the city's central plaza cracked open, and another behemoth rose up.

A pure mechanical Type IV mech, thirty-five meters tall, constructed entirely of metal, covered in spiked armor, wielding two sharp super-alloy blades, and equipped with four pairs of auxiliary thrusters embedded in its back, entered the stage.

"I didn't expect that your country has so many top-tier weapons, Lord Bei Luo!" Si Bo De praised sincerely. He wasn't just saying that; he was genuinely impressed.

The Yanas Empire had three expeditionary legions, and this wasn't even the First Expeditionary Legion. If everything was taken into account, the number of high-end weapons they possessed was considerable.

"Lord Si Bo De, you flatter us. The enemy that broke in is more tenacious than we imagined. To avoid excessive casualties and end the battle as soon as possible, we had no choice but to deploy another Type IV pure mechanical mech: Spiked Blade," Bei Luo said. She didn't smile much, as deploying a fifth Type IV mech was already a very bad outcome for her.

"I understand," Si Bo De nodded in response.

Standing behind, Su Mo curiously gazed at the newly arrived Type IV pure mechanical mech, thinking its performance seemed quite good.

Soon, the Type IV pure mechanical mech: Spiked Blade rushed towards the Black Spine Bug King at extreme speed, taking advantage of the moment when the Black Spine Bug King was fighting the two bio-mechs to appear behind it.

The two sharp super-alloy blades stabbed into the AT Field barrier!

*Crack!*

In an instant, the Black Spine Bug King's AT Field was pierced.
