As soon as they entered the passage.

Baiyu felt the entire ventilation duct was cramped and narrow, and ahead in the duct, there were many moving energies.

These were evidently the mechanical beings inside the base.

Mu Feiyan continued to crawl forward with effort. The ventilation duct was not always straight; there were many twists and turns, as well as many branches leading to different parts of the base.

Although Baiyu also didn't understand.

The Mechanical Race, rarely breathing, had so many ventilation ducts when they obtained energy from Energy Crystals.

But this ventilation duct.

Was like the sewer system of a mega city with a population in the millions, ridiculously complex.

After several twists and turns.

Under Mu Feiyan's lead, Baiyu finally arrived at quite a spacious room, where only ordinary steel floor tiles were laid, and the remaining areas were not developed.

It seems the Mechanical Race didn't have time yet, or perhaps the base was already large enough that it didn't need expansion.

"I escaped from here before. Ahead there will be many mechanical guards. They have specific surveillance patterns. Except for some fixed guards, the rest patrol cyclically. Once you understand their patrol patterns, you can avoid them."

Mu Feiyan recounted how she managed to escape from the Mechanical Race base and how she evaded those guards.

After ensuring she missed nothing.

Mu Feiyan then bid Baiyu farewell sincerely: "Warrior, I hope you come back alive. I will wait for you one night at the previous spot. If you survive, perhaps we can cooperate further!

I know this area very well.

I can even take you to the city destroyed by the Mechanical Race over there. There are many survival supplies there, enough for us to last until reinforcements arrive."

After saying this.

She crawled back into the duct.

Baiyu ignored her, jumped down the duct, leaned back against the room's stone wall, surveyed the surroundings, and, confirming he had not been detected by the Mechanical Race, then proceeded forward.

According to Mu Feiyan's explanation.

The Mechanical Race's thought processes are very rigid, essentially just more precise machines.

Whether in action or other things, they adhere to fixed patterns and individual computation systems.

These Mechanical Races, compared to human-made robots,

merely have stronger computational capacity, better quality, and greater lethality.

Of course, it might be an exaggeration to say this.

But in essence, that's the reality.

Baiyu wasn't actually afraid of getting discovered by the Mechanical Race, unless there were Mechanical Race beings higher than Level One Blade Warriors.

Without the Mechanical Race's tanks, battleships, or other terrifying weapons,

he wouldn't have much trouble dealing with a hundred Blade Warriors.

But still.

Not being discovered and staying low key wasn't a bad thing.

Using the information from Mu Feiyan, Baiyu quickly passed through more than a dozen rooms, most of which consisted of various mechanical beings conducting various research, involving other mechanical beings and various animals.

Baiyu even saw in one room a nutrient chamber containing various oddly-shaped insects.

Finally.

After passing through numerous rooms, Baiyu arrived at the research facility Mu Feiyan had escaped from.

It was a particularly large room.

Standing inside were nutrient chambers, all filled with people, their bodies pierced by tubes of different colors.

Some people.

Had already had their bodies replaced with mechanical parts.

This was some kind of human experimentation research.

Baiyu frowned, within the room were a few mechanical beings resembling octopuses, operating various instruments and pressing different buttons on the densely-packaged control panel.

These octopus robots.

Clearly special members of the Mechanical Race, likely dedicated to research rather than combat.

After all, Baiyu didn't spot any weapons on their bulky bodies.

If those mechanical arms were weapons, they'd be too weak.

So Baiyu felt they weren't equipped with weapons but were pure researchers.

At the moment.

These octopus robots were controlling data for the largest nutrient chamber. Inside was a human-like little girl.

But Baiyu noticed from her eyes, forehead, and other features, she wasn't human at all, but entirely mechanical.

"What is this?"

Baiyu couldn't understand anything on the lab's big screen.

But.

The Mechanical Race has always been capable of communicating with humans; Baiyu read at Arnold Base that they possessed language translators with 8,000 universal languages preloaded.

Baiyu thought.

As long as he captured a few Mechanical Race beings alive, he should be able to find out what was happening.

In an instant.

Baiyu no longer concealed himself, unleashing his Black Moon Divine Power.

Dark energy spiraled behind Baiyu, rapidly forming a small black hole-like vortex.

Baiyu rushed into the room.

The Black Moon Divine Power spread like a plague into the air, and the mechanical beings collapsed immediately, unable to resist.

Baiyu shattered several octopus robots' power cores consecutively.

In the end.

He fixed his gaze on the only octopus robot still operational in the room.

"Tell me what you're doing, or I'll destroy this place. I think you can easily judge which consequences are worse."

Baiyu spoke decisively.

He was certain this mechanical being could understand him.

Moreover.

It would make the correct decision.

Negotiating with the Mechanical Race was documented in books;

the Mechanical Race lacked emotion and evaluated situations based on benefit and consequences.

Simply put.

It's the way a robot thinks.

So between informing Baiyu about the place and letting him destroy it, this robot would surely choose the former.

After all.

The harm of the former was far less than the latter.

However, at that moment, the octopus robot not only didn't reply, but struggled to get up, attempting to head to the control panel and press buttons, and it emitted beeping sounds, evidently activating a self-destruct sequence.

Baiyu was slightly stunned.

Clearly, he didn't expect the robot to choose suicide over revealing the situation to Baiyu.

But.

Baiyu naturally wouldn't allow it to self-destruct.

Black Moon Divine Power instantly invaded the octopus robot's internal systems, destroying all its settings.

Seeing the mechanical bodies scattered on the ground.

Baiyu wasted no time.

The situation here would soon be exposed; he needed to uncover the information before other mechanical beings arrived.

Quickly.

He found the translation machine in the room.
