Lu Heng was unsure how many days had passed before he finally searched through Alinger, collecting all the medical equipment he could find in the city into his space.
The items here could not be replicated either, so he had to collect them one by one.
"Do you know where those passages lead?"
Lu Heng floated in mid-air, looking at the gates leading to other regions, and said to the robot behind him.
"They lead to other cities here."
The name of this residential area was Alinger, as the robots had informed Lu Heng during their previous conversation.
Each city and region had a different name.
"That's a given. I'm asking what those cities are like. Are they also residential areas like this one?"
"Not entirely. The entire Kando is divided into dozens of residential zones and several production zones, as well as some military industrial zones, mechanical zones, and quarantine zones, not to mention the main control zone and management zones."
Iron Man One pointed in various directions. "These are all leading to residential zones, and the layout of those residential zones is exactly the same as here."
"If they're all the same, won't people get lost?"
"There's a positioning system."
Right, he had forgotten about the technological level here. He guessed that as long as he entered the name of the place he wanted to go, the system here would automatically guide him there.
Since the residential areas were all the same, Lu Heng had nothing else he wanted to see for now.
"Where are the areas we can go to?"
Based on Lu Heng's inference, ordinary residents would definitely not be able to enter some special areas.
For example, places that produced robots or certain high-tech military products should only be accessible to people with special identification.
"Production zones."
As expected!
Iron Man One then educated Lu Heng on the functions of the production zones.
The production zones were divided into agricultural operation zones, breeding zones, and processing zones.
Lu Heng planned to start with the agricultural operation zones and gradually understand the local livelihood, thereby obtaining more secrets about the longevity of these alien creatures.
In fact, the human brain had only developed less than 20% of its functions, which might be related to the relatively short lifespan of humans.
Lu Heng felt that if human lifespan were increased, making them as long-lived as the Senal people, humans could also create higher technology in the future.
"How can I enter other areas?"
"You need corresponding identity verification, which requires going to Selby under the management zone."
This was a bit troublesome. It was likely that there were no living aliens left in this artificial space city, but even if there were, these aliens would not be able to process identity documents for him.
Taking a deep breath, Lu Heng pointed towards the direction of the production zone. "How do we get there? Do we still travel between regions using flying vehicles?"
"Certainly not. To go to different regions, you must take the inter-regional transport vehicles."
"Then let's go."
Bringing the two robots, Lu Heng followed behind the robots in one direction.
At the high-altitude entrance and exit, Lu Heng saw the transport vehicle controlled by Iron Man One.
Lu Heng entered the transport vehicle with the two robots. Inside, there were several rows of seats. The robots indicated for Lu Heng to find a seat.
The moment Lu Heng sat down, a safety belt fastened around his waist, securing him in the seat.
Lu Heng turned to look at the two robots; they had designated standing positions.
They stood on fixed docking points, and then a "click" of metal buckles was heard from their feet. The robots' feet were firmly secured in the carriage.
After a brief pause, the carriage doors were closed.
There were no windows in the carriage, so Lu Heng could not directly see the transfer route from inside.
There was an electronic light screen in front, displaying a virtual path.
After an electronic sound of "Beep!", the virtual path on the light screen changed, showing the route that had been traveled.
Lu Heng did not feel any discomfort inside the carriage. After about the time it took to smoke a cigarette, Lu Heng heard another electronic sound.
"Beep, beep, beep."
The carriage doors were opened, and the restraints on Lu Heng and the robots were released.
Lu Heng followed the robots out of the carriage.
Before him was a brilliantly colored region.
Standing on a high platform, Lu Heng could see vast fields below.
The fields were divided into countless plots, planted with plants of different colors.
After observing for a few seconds, Lu Heng's eyes narrowed.
Something was moving and shuttling between the plants.
Lu Heng asked Iron Man One beside him, "What is moving below?"
"Agricultural robots."
Fortunately, it wasn't aliens. Lu Heng had been startled by his own guess, fearing that he might encounter aliens who hadn't left in other areas.
"There are also these types?"
"Yes, they are not sold to outsiders, and only here will you find this type of robot."
However, to prevent his previous speculation from actually happening, Lu Heng did not rush down. Instead, he turned to the robot and asked again, "Are there any Senal people left in this space city?"
Time seemed to stand still, and he did not receive an immediate response. Lu Heng felt his breathing becoming rapid.
"Master, there are no Senal people in the city."
"What about other species? I mean, living creatures."
"Yes."
"Where? What are they?"
This answer made Lu Heng's back feel cold and damp. Could it be that the alien species that invaded the Senal people had not left?
"It's you, Master."
Iron Man One, through scanning, could distinguish that Lu Heng was not a Senal person. However, their initial settings did not specify that only Senal people could contract these robots.
It was likely that the Senal people had not expected that the space city they lived in would one day have a creature of another species enter in such a special way.
Lu Heng was somewhat uncertain about how robots, or rather the Senal people, described living creatures, and whether there were cognitive differences.
He remembered that Bona had said that zombies were also a type of creature to them.
In their eyes, they were the same as humans.
Never mind, he would go down and take a look first.
Opening the flying vehicle, Lu Heng led the robots towards the fields below.
The plants grown here were very brightly colored, and Iron Man One kept pace with Lu Heng, explaining the uses of various plants.
"These blue ones are raw materials for the daily food of the Senal people."
"These yellow ones are raw materials for a type of seasoning..."
As they shuttled through the colorful plants, Lu Heng listened to the robot's explanations while observing the agricultural robots at work.
These robots used for farming and labor did not have artificial skin covering their metal bodies.
The exposed metal framework allowed Lu Heng to clearly see their structure.
A blue energy core was embedded in the chest cavity of the labor robots.
