222: The powerful Krolm mechanical army

Ran Quan and the others followed the blond man from a distance, heading towards The Ground.

On The Ground.

The Fifth Defense Line of The Ground's safe zone 2A.

Boom! Boom! Boom!

Countless "mass-produced scout robots" charged forward; looking at their numbers, a vast expanse, there were at least several hundred thousand of them.

Behind them, dozens of spread-out [spider-type transport machines] were slowly advancing.

And new machines also appeared:

Mechanical dogs that burst out from behind the "mechanical swarm" and overtook the "mass-produced scout robots."

Each of these mechanical dogs was the size of a calf, but even longer.

With steel fangs and claws, their open mouths contained a section of a cannon barrel, allowing them not only to bite but also to fire.

They possessed a certain long-range attack capability; of course, you wouldn't want to be bitten, or else you'd experience the joy of a mechanical dog's 'mouth blast.'

There were also combat aircraft sweeping through the air, which were, literally, flying combat machines.

Their appearance was more sci-fi, and they lacked cockpits, being purely mechanical creations.

There were also newly introduced war robots: which could be called Gundams.

Over five meters tall, humanoid, equipped with numerous "missile launchers," "heavy cannons," and "heavy machine guns." The material they were made of was several times better than that of "mass-produced" robots, and they also had "armor" on their bodies, making their defense N times stronger. Their double arms had a piece of armor that could not only extend energy cannons but also eject energy light swords.

And don't let their five or six-meter height fool you; they moved extremely quickly, just like agile humans. (You can refer to Cybertron.)

These war robots, at a glance, were much, much stronger than the "mass-produced" scout robots.

These were all the "mechanical types" Krom possessed; their war uses were limited to these, as one couldn't expect too much. They were only a Level 1 world, a mechanical civilization (after all, the Wasteland World - Saida World was also a Level 1 world).

Meanwhile, the Underground World, due to population issues, had most of its defensive facilities unmanned.

In this regard, they also performed exceptionally well.

"Retreat! Retreat! Retreat!" Decisively, the Fifth Defense Line's garrison immediately retreated, driving various combat vehicles, fighting as they withdrew.

The defensive facilities in the positions continuously attacked under automatic intelligent control.

"Report! The Fifth Defense Line in Ground Zone 2A has fallen!"

"Report! The Fifth Defense Line in Ground Zone 6A has fallen!"

"Report! The Fifth Defense Line in Ground Zone 7A has fallen!"

"Report! The Fifth Defense Line in Ground Zone 9A has fallen!"

"Report! The Fifth Defense Line in Ground Zone 11B has fallen!"

Headquarters received numerous reports at once.

Almost all defense lines fell almost immediately upon Krom's attack.

All forces retreated to the Fourth Defense Line. Of course, the Fifth Defense Line also served a certain purpose.

It destroyed many of Krom's robots, obtained first-hand intelligence on the enemy forces, and also delayed their advance, buying time for the rear.

And Ran Quan also received this news.

"Good heavens! They're attacking so fast!" Bai Mo heard Ran Quan's words, so many places falling at once.

Just hearing it, it felt like the Underground World was collapsing, completely falling and being invaded.

"Let's split up!" Yi Xin said. The battlefield was too large, and it wasn't good for them to all gather together, wasting combat power and affecting their individual earnings of "source points," so splitting up was the optimal choice.

"No problem!" Lin Zifeng nodded. Everyone exchanged glances and tacitly scattered.

Ran Quan, Miya-pasu, and Bai Mo went to Ground Zone 2A nearby.

Upon arriving, they saw many soldiers preparing to depart, and a large number of combat vehicles had already driven out.

Not only that, but a continuous stream of "workers" brought many materials, preparing to add defensive facilities to the Third, Second, and First Defense Lines.

Krom's offensive was too fierce.

Especially since mechanical life forms do not possess emotions and behaviors like "fear," "dread," or "retreat."

Everything is for the "Supreme"!

They are fearless in death.

They are brave in charging.

And the Saida World, facing Krom, also displayed powerful teamwork.

The combination of humans and technology, fighting against the power of machines.

"The battle has begun! Let me find... where are you damned opponents!" A Reincarnator from the Saida World's faction opened his eyes, the blood vessels around his eye sockets slightly bulging, and his pupils turned grayish-white.

"Found one!" Chen Mu discovered a person mixed within Krom's army, "ambushing" Saida World's defensive facilities on the battlefield.

His destruction speed was even faster than Krom's army.

Whoosh! Chen Mu immediately burst forward.

"Eight Inner Gates Formation - Fourth Gate - Gate of Limit, Open!" A faint green aura burst forth from Chen Mu's body.

At the same time, his eyes transformed into a scarlet, large pinwheel pattern.

"Hmm?" The Reincarnator from Krom's faction who was being ambushed immediately sensed Chen Mu's approach, and a strong aura instantly erupted from his body.

The two instantly collided.

Boom!!!

"What's happening over there?!" Their battle was instantly detected by the Three Great Technologies.

They discovered that the two terrifying beings were actually "humans"?! They immediately exchanged glances, each thinking it was one of their own people... when did they secretly produce such powerful superhumans?

Of course, this thought was just a fleeting one; everyone knew the situation, and they each had "undercover agents," so they were well aware.

Furthermore, in the current situation, who would still hide things? And those two were fighting each other, clearly not allies.

"A time of trouble!" Everyone immediately knew that these two seemed to be from "other worlds," after all, whose eyes were that strange, and whose body would emit aura.

One came from Krom's mechanical civilization, and one came from their side.

Clearly, they had been "lurking" for a long time and burst out today.

Perhaps, this incident also had them pulling strings behind the scenes?

There were too many suspicious points, and the high-ranking officials of the Three Great Technologies also had headaches. However, the most important thing now was the war; only by securing victory could they think about other things, otherwise, if they lost, there would be nothing left to think about, because everything would be gone.

However, all necessary preparations still had to be made.
