The many officers who were besieging the Black Thorn Worm King were overjoyed to see its AT field being pierced.

They watched with excitement as the IV-generation pure mechanical mecha, Spiked Blade, ambushed it from behind, hoping to inflict heavy damage on the Black Thorn Worm King.

However, they underestimated this IV-type lord-class Black Thorn Worm King.

The instant its AT field was shattered, it twisted its body and swept its slender, hooked tail across.

Spiked Blade was shocked and hurriedly raised its dual super-alloy blades to block.

Bang!

The enormous force of the impact sent Spiked Blade crashing into a distant building like a cannonball.

Rumble!

The Black Thorn Worm King then opened its mouth and let out a chilling roar.

Its biological energy reaction instantly soared.

In the next moment, the destroyed AT field barrier was reconstructed.

This scene filled everyone besieging it with despair.

Su Mo, standing behind Sperd, was also slightly moved, secretly thinking that this Worm King was unusually ferocious.

It was planning to take on three at once!

Su Mo subconsciously glanced at Bei Luo, whose beautiful face was now clouded with gloom, clearly in a terrible mood.

Of course, no one could be happy facing the current situation.

At this moment, the three IV-generation biological mechas reorganized and charged at the Worm King from three directions, preparing to launch a combined attack and inflict heavy damage.

Unfortunately, the Black Thorn Worm King was not foolish. It flapped its wings and viciously rammed straight into Shadow Blade.

Not giving them a chance to combine their attacks.

Shadow Blade had no way to dodge. The moment they collided, it was sent flying.

At the same time, Red Eye and Spiked Blade charged up and simultaneously slammed their weapons onto the AT field barrier.

The entire field twisted violently, but it still blocked their attacks.

The Black Thorn Worm King then swept a sharp claw at Red Eye, sending it flying as well.

Spiked Blade activated its reverse thrusters, rapidly pulling away.

However, the Black Thorn Worm King turned its head and charged up a beam, firing it directly at Spiked Blade. The mecha desperately activated its energy shield.

Accompanied by a burst of light!

Spiked Blade was blasted away.

Even facing three opponents, the Black Thorn Worm King remained as formidable as ever, showing no signs of being at a disadvantage.

The Black Thorn Worm King flapped its wings again and moved towards the southern part of the city. The surrounding swarms of mechas charged forward, desperately trying to intercept it.

"Stop it!"

The Black Thorn Worm King angrily tore apart the approaching flies.

......

On the high platform, Bei Luo unconsciously clenched her right fist. The current situation was a bit beyond her expectations.

That damned bug was getting closer and closer to the lab, which was not a good thing at all.

Sperd noticed Bei Luo's awkward situation and suddenly suggested with a smile.

"Lady Bei Luo, this battle can't continue as a stalemate. Of course, I'm not doubting your country's strength, but I think continuing to fight like this will cause significant casualties to your people. If you don't mind, how about letting my people join the battle and lend a hand?"

The officials of the Aounas Kingdom looked at each other upon hearing Sperd's suggestion.

They really wanted to say, "We don't need it!"

But the problem was that they couldn't bring themselves to say those words given the current situation. However, they were also conflicted. It would be a great loss of face to really let their guests help.

Bei Luo took a deep breath. She was also a thousand times unwilling. But the current situation was very grim. The three IV-generation mechas couldn't stop the Worm King, and it was getting closer and closer to the lab. If it attacked the lab, the trouble would be immense.

Thinking of this, Bei Luo finally released her fist and said, "Then I'll have to trouble Lord Sperd."

Lord Sperd then turned his head and glanced at Wenluosi, signaling her with a special look.

Wenluosi immediately understood. She leaned close to Su Mo's ear and whispered, "Su Mo, I'm sorry to trouble you to make a trip. Also, Lord Sperd told me to remind you that you can only kill one. Don't kill both and save some face for the Aounas Kingdom."

Su Mo's expression was extremely interesting after hearing Wenluosi's words. He couldn't help but smile wryly in his heart.

This Sperd really thought highly of him. These two bugs were so ferocious, it was already hard enough to kill one, and he was still worried that he would kill both.

He really didn't know whether to be happy or complain.

Of course, despite his surprise, Su Mo still calmly said to Sperd.

"Understood!"

Then he turned and left.

Bei Luo glanced at the departing Su Mo. She was also secretly pondering Su Mo's strength.

Of course, Bei Luo didn't say much.

Time passed slowly.

A dozen minutes later, the ground in the central square cracked open again. Su Mo made his official debut, piloting the IV-generation biological mecha, Gluttony.

Sperd smiled slightly as he looked at the Gluttony mecha that had appeared.

He then spoke to Bei Luo.

"Lady Bei Luo, leave that Worm King to our people. You can have your people besiege the Queen Worm."

"Lord Sperd, aren't you being a bit too confident?"

Bei Luo's heart skipped a beat when she heard Sperd's words.

Sperd did not answer Bei Luo's words, but simply raised his hand and spoke into his wrist device to Su Mo, "Su Mo, I'll leave that Worm King to you!"

"Understood!"

Su Mo's voice soon rang out.

In the next moment, the Gluttony mecha's eyes suddenly lit up, and a terrifying aura spread out. The AT field instantly deployed!

"AT field!"

Bei Luo's heart jumped. She knew that none of their IV-generation biological mechas were capable of deploying an AT field.

Immediately afterward, the entire Gluttony mecha stomped heavily on the ground, causing it to cave in. The entire mecha transformed into a streak of light and charged toward the Worm King.

The Black Thorn Worm King instantly sensed extreme danger.

It abruptly turned around to meet the attacking Gluttony mecha!

The two collided, and their AT fields twisted violently!

A massive shockwave swept out.

The three Shadow Blade mechas that were originally besieging it were directly forced to retreat. The pilots were also dumbfounded, shocked by this sudden, uninvited guest.

Gluttony broke through the Black Thorn Worm King's field barrier and instantly closed in. It quickly drew the super-alloy blade from its waist and slashed at the Black Thorn Worm King.

The Black Thorn Worm King blocked with its sharp claws. The two collided and crisscrossed, sending sparks flying.

However, Su Mo's next attack was too fast, so fast that the Black Thorn Worm King had no time to block it. It was immediately slashed.

Tear~

Viscous blood flowed from the shocking wound.

Bei Luo suppressed the shock in her heart, raised her left hand, and issued an order to the three IV-generation mechas through her wrist device.

"Change attack targets. Everyone besiege the Queen Worm. Hurry!"

"Yes!"

Three voices rang out from within the wrist device.

Immediately afterward, the three Shadow Blade mechas charged toward the Queen Worm.
