The underground is very dark.

Due to Baiyu's destruction of the research institute, the lighting equipment below was disconnected from the top and naturally stopped functioning.

Baiyu relied on the high-power lighting equipment he carried to move forward in this dark environment.

It took about ten minutes.

Baiyu toured the small underground dark room.

Here.

It was unexpectedly another laboratory.

Just like the previous base.

Inside, one nutrition capsule after another contained people captured by the Mechanical Race, and the large screen, lacking energy, had already gone dark.

In the middle of the laboratory, there was still a giant cultivation capsule.

Inside was the Mechanical Race girl.

She looked identical to the girl Baiyu had seen in the Mechanical Race base before, except the expression inside the cultivation capsule was different.

Inside this cultivation capsule.

The girl seemed more contemplative.

Baiyu frowned.

Previously, in the Mechanical Race base, that little girl was not affected even when the base exploded.

Instead, she directly flew away, leaving Wood Iron Star, returning to the Mechanical Race warship in Earth's orbit.

With the experience from last time.

This time, Baiyu did not act recklessly; breaking the cultivation capsule might cause the girl to escape again.

Just as he was preparing to approach slowly and capture this Mechanical Race girl.

Suddenly.

The other nutrition capsules underground burst open, countless liquids spilling out, and human corpses collapsed onto the ground.

Completely lifeless.

The people inside those nutrition capsules were all dead.

Baiyu at this moment stared at the giant cultivation capsule in the middle, tightly gripping the Black Moon Blade, ready to respond to any changes.

A few seconds later.

The giant cultivation capsule in the middle began to develop cracks, rapidly spreading like breaking ice.

The next moment.

The entire cultivation capsule exploded, accompanied by a harsh screech.

This was evidently some kind of sonic weapon.

The sharp screech shattered everything around Baiyu, from the base of the nutrition capsules to the laboratory tiles, almost instantly destroyed.

Baiyu used Blood Qi to protect his body just in time, preventing any impact.

After the screech.

The little girl stepped out from the cultivation capsule, her eyes as blue as crystal gems, surveying her surroundings.

"What is your status level within the Mechanical Race?"

Baiyu asked cautiously.

Although the little girl didn't attack, he could sense that she was a formidable opponent. If it came to a fight, it was uncertain who would win.

"Me?"

The little girl spoke hesitantly, yet continued slowly, "I am an experiment of the Mechanical Race, called 'Contemplation.'"

Indeed.

The girl's previous expression in the nutrition capsule was like that of a thinker.

And at this moment.

Even stepping out, her face consistently showed contemplation, with no other expression.

Baiyu couldn't help but recall the previous human creation plan of the Mechanical Race.

They wanted to create Mechanical Race beings with true emotions, able to think and have various feelings like humans.

Evidently.

This was a large-scale undertaking.

According to information from Arnold, the Mechanical Race had been invading Wood Iron Star for a year. During this year, aside from dismantling the resistance forces and social structures on Wood Iron Star, the Mechanical Race evidently also established many bases of their own.

They used these bases to conduct this experiment!

Capturing Wood Iron Star people to use as test subjects, attempting to create Mechanical Race beings with complete human emotions.

And their method of creation.

From the Mechanical Race's usual methods, Baiyu had already deduced the majority.

Evidently, they analyzed the full range of human emotions, behaviors, and actions, disassembled everything, and simulated them individually.

Baiyu wasn't sure what the girl in the previous base was simulating.

But the one in front of him now.

Was surely simulating human "thinking" behavior.

Mechanical Race beings don't think; they use algorithms and various programs to make the most correct actions.

However.

In long-term warfare, the Mechanical Race evidently realized their unique existence.

In simple terms.

This method of operation has both advantages and disadvantages.

The most baffling thing for the Mechanical Race was that in their battles with the human race, although they could win many battles, human forces always managed to unleash counter-attacks at the brink of defeat, completely reversing the situation in the battlefield.

After multiple occurrences of such events.

The Mechanical Race wanted to learn from humans, to mimic them, hoping to gain this ability.

The result.

Naturally gave birth to the plan Baiyu was witnessing.

This little girl evidently represented the emotion of "contemplation."

"You say, why am I here?"

"Why are you taller than me?"

"Why do I feel incomplete…"

The girl sat on the base of the nutrition capsule, starting to mutter to herself.

Baiyu at this moment gripped the Black Moon Blade, slowly approaching the girl: "I can feel you are now very troubled, aren't you? With a mess in your mind, wanting to know everything but having no answers, relying on yourself to think."

The little girl tilted her head, looking at Baiyu: "Yes, can you tell me why? I want to know…"

"I can't.

But I can do another thing."

Baiyu showed a smile.

The girl instinctively asked: "What thing?"

"To help you escape suffering and get relief from this painful world sooner."

Suddenly.

Baiyu swung the Black Moon Blade down, slashing the girl, cutting open her skin.

However.

What surprised Baiyu was.

The girl's skin turned out to be real flesh and blood, rather than Mechanical Race components.

Yet this horrified Baiyu even more.

Because his full force coupled with the Black Moon Blade should have shattered even a steel person, yet this girl endured the blow with flesh and blood, merely suffering a superficial wound.

When Baiyu withdrew the Black Moon Blade.

The wound on the girl's shoulder quickly healed, leaving no scar behind.

What on earth is this thing.

At this moment.

Baiyu immediately felt a bit eerie.

"What are you doing? Are you trying to see if you can kill me?"

The girl frowned, lightly scratched herself with sharp nails, opening the abdomen's skin, but only one or two drops of blood came out, and the wound instantly healed.

"I don't feel any energy loss; evidently, the damage from the wound was less than one billionth, data already too small to calculate."

The girl puzzledly asked: "Why can't you kill me? I feel you are very strong…"
