The addition of the robot servant brought great help to Xu Xi.

He was completely free from the rigors of laboratory maintenance.

I can devote myself to science.

Go enjoy.

Go explore.

Researching various technologies of the Human Federation at an increasingly astonishing speed.

With the help of 9090, Xu Xi even repaired the power armor so that it could function normally.

"Finally... after such a long time, it's finally done."

The sunlight passed quietly through the collapsed beams and broken steel bars, and was finally cut up and chopped apart by countless mechanical wreckages, leaving only a few strands that fell sacredly in front of Xu Xi.

impartial.

Hit the surface of the alloy armor.

It was a reflection as brilliant as a gem, gorgeous and triumphant, yet also cold and cold. It was a humanoid heavy firepower armor that only genetic warriors were qualified to wield.

Tall, mighty, and domineering.

With such a power armor, the combat effectiveness of the Xu system will be greatly improved.

At least.

He is not afraid of ordinary rebellious omnics.

"Perhaps, it's time to step out of the laboratory and take the initiative to attack those intelligent machines," Xu Xi looked at the power armor and thought seriously.

He has mechanical power and can amplify the power of machinery.

The already terrifying power armor will become even more exaggerated.

However.

It is always better to be cautious.

It's always right.

"Although this is not a major city of the Federation, there are quite a few rebellious omnics here, including some like the Mechanical Eagle, which are airborne and can completely overwhelm land units."

"Anyway, I am not qualified to be arrogant right now."

Xu Xi pondered for a while.

Just when I was feeling thirsty, a glass of water appeared in front of me at the right time.

"Thanks, 9090," Xu Xi took the water and drank it all in one gulp.

"It is my honor to serve you." The cold, mechanical electronic synthesized sound echoed in the empty underground.

No emotion.

No ups and downs.

Inexplicably, Xu Xi recalled the former witch.

There are some similarities between witches and servants, but specifically speaking, there are still differences between the two.

The witch herself has emotions, but she has been subjected to great malice and has closed herself off.

9090 is a heartless machine.

Their birth and essence are dead things without souls.

"Heart..." Thinking back to the past performance of the robot servant, Xu Xi was very emotional. Perhaps, he could hope to see the birth of a miracle.

The soul's gorgeous flowers bloom on dead metal.

Showing the brilliance of "humanity".

Xu Xi had an inexplicable premonition that that day would come soon.

"9090, I have to go out to inspect the condition of the solar panels. The laboratory will be left to you to guard," Xu Xi looked at the time and found that it was already afternoon.

He decided to inspect the layout of the surrounding solar panels before the sun set.

"Yes, don't worry."

The core of the servitor glowed.

There was a huge "smile" on the screen, stagnant and monotonous, looking very stiff.

No explanation is needed.

When Xu Xi walked to the door, naturally, a robotic arm and weapons were sent along the slide rails and installed on Xu Xi's body.

The location of solar panels is not dangerous, most of them are in light-filled places underground.

The very few that were placed outside were hidden using special technology and were not far from the underground laboratory.

But living in a dangerous doomsday where intelligent machines are everywhere.

Vigilance is necessary.

"Click-click-click", Xu Xi clenched his fists, and the next moment, the exoskeleton robotic arm made corresponding movements in sync.

There are traces of rust on it, and the metal armor is damaged in many places, revealing the internal mechanical structure and wiring.

This is normal.

After all, I have been using it for several years.

During this period, whenever the Xu family encountered danger, they almost always relied on the robotic arm to save the situation.

"Don't worry, old friend, you'll be able to retire soon."

"Once the power armor is fully recharged after debugging, it won't be your turn to appear."

Xu Xi walked out of the laboratory door.

The passage is dark and visibility is poor.

Only a few golden rays of sunlight penetrate through the strange and dense gaps, reaching the corners with difficulty, adding light to this dark world.

Snap——

Snap——

Xu Xi walked very slowly.

The rise and fall of steps caused the body to sway slightly, causing the weapons and equipment on the body to collide and resonate.

That sound is quite subtle.

But in the silent underground passage, any sound would be amplified several times in an instant.

Then, the clear and crisp sound of footsteps scares away the timid creatures in the darkness, causing them to flee in panic.

"The energy provided by solar panels is ultimately too limited."

"Over the years, I have added a lot of new panels to keep the water and electricity system running, but if it's that power armor..."

"As expected, we still need to switch to a new energy system."

Xu Xi was thinking while walking.

This is not his first time inspecting solar panels.

Long-term repetition allows the body to form muscle memory, so that every time you reach a location, you can complete the inspection at an extremely fast speed.

Soon, the inspection of the underground solar panels was completed.

Xu Xi turned around and walked towards the surface, checking the several solar panels scattered near the entrance and exit one by one.

At this point.

As the inspection work is completed.

It was getting darker.

The heat faded, the cold came, and tiny dots of starlight appeared in the sky.

It's not very shiny, but it looks particularly magnificent when paired with the clear sky.

"it's beautiful."

Xu Xi exclaimed, then packed up his things and turned back. Before leaving completely, he noticed that the camera was set up at a slightly upward angle.

Without thinking too much, Xu Xi quickened his pace and left.

soon.

Xu Xi returned to the familiar laboratory base.

As I entered the gate and took off my heavy gear, a familiar mechanical welcome sounded in my ears:

"Welcome home, Master."

"Well, I'm back."

As Xu Xi spoke, he subconsciously looked at the screen in the laboratory.

That is not only the screen for 9090 to express itself, but also the screen for linking to external surveillance cameras.

In the past, the screen only showed the entrance and exit.

But today is different.

Because the camera is tilted upward, the screen image is synchronized with a gorgeous starry night sky.

Everything was very quiet in the laboratory. Xu Xi could feel that 9090 was "gazing" at the starry sky, observing its mystery and brilliance.

Servant 9090 has no body.

All calculations are carried out in the immobile core.

But it controls every part of the laboratory, and wherever the machinery extends, it is within its control.

The cameras at the external entrances and exits are actually equivalent to 9090's eyes.

Xu Xi suddenly realized that the reason the camera angle was raised was because 9090 was looking up at the night sky.
