"Ah, is this going to work? And even if we successfully break through, with so many monsters swarming, the fall of this city is only a matter of time. What if we go in, and then they collapse right after? Wouldn't we be walking right into a trap?"

"Enough with the nonsense. I know it's dangerous, but do we have a choice? No matter what, we have to rescue the target personnel. Alright, everyone, follow me!"

As soon as Su Mo finished speaking, he controlled the Dark Knight, rushing towards Mist City at top speed.

Sun Duo Xiang, gritting his teeth, piloted his mecha and led his subordinates to follow.

"Everyone, stay close to me, activate all energy shields, and don't fly too high!"

Su Mo reminded them, looking at the intense anti-air weapons and dense monsters in the sky.

"Yes!"

Everyone responded.

Su Mo controlled the Dark Knight, lowering its flight altitude, entering the black mass of monsters at low altitude.

Sun Duo Xiang couldn't help but glance down, trembling all over. If they were shot down and fell in, they would definitely be torn to pieces.

In fact, it wasn't just Sun Duo Xiang who was scared out of his wits; every subordinate had their heart in their throat.

Although Sun Duo Xiang's subordinates were all desperate people,

the scene before them was beyond terrifying.

Just then, the monsters below, like a tide, spotted Su Mo and the others, and fired beams of light at them.

Su Mo dodged with the mecha to the extreme, the beams of light passing by their sides.

*Boom!*

"Damn, I've been hit!"

...

In the communication channel, an angry voice sounded from time to time.

Fortunately, they were all piloting IV-generation pure mechanical mecha, Night Watchers, which were considered the worst among IV-generation mecha. But after all, they were IV-generation mecha, and their energy barriers were still quite strong. Unless hit by a high-level monster, they could still withstand the attacks.

"Everyone, be careful, and don't slow down!"

Su Mo commanded, his nerves tense.

At this moment, a grotesque III-type bug with grayish-white butterfly wings flew out of the monster tide and pounced on Su Mo.

Su Mo, quick-witted, swung the particle light blade, slicing it in half with one strike.

In that split second, hundreds of beams of light, large and small, crashed violently onto the Dark Knight's AT field barrier.

*Rumble*

Su Mo immediately felt like countless ants were biting his head.

He endured the discomfort and accelerated his advance.

Just then, a slender tentacle suddenly swept up from the monster tide, instantly entangling a Night Watcher and dragging it down.

An anxious cry rang out in the communication channel.

"Zack!"

"Don't stop! Everyone, accelerate forward, no matter who it is. Unless the boss gets shot down, no one is allowed to stop, including me!"

Sun Duo Xiang shouted violently.

In fact, Sun Duo Xiang's judgment was correct. The Night Watcher that was dragged down was instantly submerged by the monster tide, and many IV-type monsters pounced on it.

Then, Zack's voice sounded in the communication channel.

"Goodbye, brothers! I'm going to fight them!"

Then, a sky-piercing explosion spread out, blasting away a group of monsters. As it was being torn apart, Zack detonated the mecha's built-in Exploding Bear missiles.

Su Mo also felt extremely stifled. If he were piloting a V-generation bio-mecha, he could sweep through directly, but unfortunately, he was only piloting a IV-generation bio-mecha.

"Don't have too much emotional fluctuation, negative energy pollution will erupt."

The Counterfeit Creator Devourer immediately reminded Su Mo, sensing the fluctuations in his emotions.

Su Mo took a deep breath, suppressed the negative emotions of anger and violence in his heart, and calmly controlled the mecha to continue advancing.

At this time, a large number of monsters jumped out of the monster tide and pounced on them, while a swarm of insects also surged towards them from the sky.

"Everyone, stay close to me!"

After Su Mo finished speaking, his pupils shrank, and a portion of his negative energy surged out instantly. The biological tissue of the entire Dark Knight swelled, the mecha emitted a red halo, its eyes became scarlet, and its biological reaction soared!

Then, Su Mo controlled the Dark Knight to swing the dual particle light blades, sweeping away the rushing insect swarm like cutting vegetables.

At this moment, the Dark Knight was like a sharp knife piercing through all obstacles, clearing the way for his subordinates behind him.

...

On the west side of the defensive wall.

The defending soldiers of Mist City were operating various weapons, frantically pouring firepower to block the attacking monsters.

"Give me everything you've got, don't be stingy with ammunition!"

A commander roared hysterically.

"It's not working, Captain, we can't hold on, the monsters are about to break through, ah!"

In the communication channel, a team member's anxious shout sounded, which turned into a scream in an instant.

"Damn it, immediately deploy Large Weapon: Peaceful Giant Bears!"

"Yes!"

The subordinates responded immediately.

Soon, special launch ports unfolded,

revealing round, giant missiles, which were then launched.

Before long, small bear heads rose up.

The terrifying shock wave swept through a part of the area, scattering the originally dense tide.

Unfortunately, it was useless. The surviving monsters continued to rush towards the city wall madly.

"Captain Bute, the monsters are coming up."

"Kill them all! Clean them up."

Captain Bute piloted a Night Watcher mecha, rushing towards the monsters climbing the city wall, swinging his light blade, killing one with each strike.

Blood splattered everywhere.

The remaining soldiers on the entire city wall controlled their mecha, fighting to the death in close combat.

Unfortunately, the number of defense mecha was too small, and the number of monsters climbing up was too large.

One third-generation mecha after another was knocked down by the monsters.

Desperate screams continued to sound in the communication channel.

Bute had just killed a III-type Bai Ze when four or five more Bai Ze rushed up, as if they were endless.

Looking around, the entire city wall was covered with monster figures, and his own soldiers were falling one by one.

"Damn it!"

Bute felt an immense despair at this moment, unable to see a glimmer of hope. Their unit was about to be finished.

Seeing that the city wall was about to be breached,

a pitch-black IV-generation bio-mecha landed on the city wall first, with swift and decisive strikes.

One Hei Yuan beast variant after another was beheaded.

Then, one Night Watcher mecha after another followed.

They drew their alloy blades and slaughtered the monsters rushing up the city wall.

Before long, the monsters surging onto the city wall were mostly cleared away, and the situation suddenly turned from danger to safety.

Bute looked dazedly at the advanced mecha that had rushed onto the city wall, wondering where these mecha had come from. There were no Mist Country markings on their chests.

"Who are you?"

Bute suddenly thought of something and asked with a bit of excitement in his voice.

"We are sent from the Star Ring City."

Su Mo said calmly.

"Reinforcements! That's great, the reinforcements have finally arrived."

Bute was so excited that tears streamed down his face, and the other surviving soldiers were also elated.
