Lu Heng's space only required him to pass through the spatial barrier the first time.
Once he had traversed the spatial barrier and reached the other side of the space, he could travel there with a mere thought.
Therefore, this time, he had specifically used mental traversal to prevent Evan from finding him and leaving this place for the Senar alien space city's barrier.
Upon arriving in the space city, Lu Heng summoned his robot nanny.
The environment here was still too unfamiliar for Lu Heng. To find items in a place he was not familiar with, he still needed the help of the locals.
He showed the recorded video to the robot. Although Lu Heng's phone could not display it in three dimensions, the recorded footage was fortunately three-dimensional.
After scanning, the robot nanny searched its internal database.
"Can you find it?"
"Master, there are a few models available here."
"Alright, then take me to see them."
Afterward, Lu Heng also brought his flying device and followed the robot towards the items he needed to find.
Passing through several tall buildings, Lu Heng followed the robot to the rooftop of a large building.
Lu Heng didn't understand why he was brought here, but with the robot nanny's next action, he understood.
After the robot nanny landed, it scanned the surrounding objects and quickly found what it was looking for.
It approached a wall and pointed at it.
"It's behind here, Master. Should I take it out directly?"
"Not yet, let me see what it is."
In response, the robot placed one hand on the outside of the wall, and soon a hole large enough for a person to pass through opened up in the wall.
Behind the hole, the area originally obscured by the wall was also exposed.
Some items that were clearly mechanical equipment were piled up, and it seemed this thing was still operating.
However, Lu Heng did not see the object from the video.
"Do I need to dismantle something else? This thing should still be running, so what is its function?"
"It's at the center of this equipment, it's the energy source, controlling the energy supply within this building."
"Hmm, then dismantle it."
Many parts of this city were already damaged. Damaging equipment in an empty building where no one lived wouldn't make much difference.
Upon receiving Lu Heng's command, Lu Heng found a suitable position, took out his phone, and began recording how the robot dismantled it.
Under the robot nanny's operation, a blue object was retrieved.
Lu Heng looked at it; it was indeed similar to the object in the video.
This thing had been providing continuous energy to this tall building. Even after the Senar aliens had left for so long, the equipment here was still operating normally.
Lu Heng put the robot nanny away and then returned to his space with the newly retrieved energy source.
He reappeared, and Evan was already modifying and dismantling some of the equipment they had just found.
Sensing a powerful energy source, Evan stopped what he was doing and looked at Lu Heng.
He was slightly surprised, not expecting Lu Heng to find this energy source so quickly.
Once again confirming that Lu Heng could quickly travel back to the Senar alien territory, Evan's mind was constantly analyzing how to accelerate the feasibility of his return there.
"See if this is it. It was quite hard to find."
Lu Heng placed the item on the ground in his space and spoke, interrupting Evan's analysis.
"Yes, this is it. This was dismantled from a building and can be used to supply that satellite base station."
Lu Heng nodded, estimating that with this, as long as the equipment there was not subjected to further man-made damage, it could be used continuously after this repair.
Taking Evan and the equipment he found back to the satellite base station, Lu Heng began watching Evan repair it.
At the same time, Lu Heng also set up several recording devices from different angles. Although he didn't need to understand Evan's operations, these could be left for the professional personnel at the base.
Lu Heng estimated that these could all be passed down as teaching materials in the future.
Evan's operations were quite fast. After the few goals Lu Heng proposed, it performed maintenance and adjustments to the equipment here.
Once this satellite base station was built, it wasn't something anyone could use. The usage rights here were initially to be controlled by Nameless City.
By controlling these devices, Nameless City could also monitor and communicate with the world.
The purpose of doing this was not for Lu Heng to investigate the secrets of other human organizations, but to prevent any rebellious selfish intentions from arising among the personnel of various base organizations.
After all, after so long in the apocalypse, after enjoying absolute power, many people would develop some improper thoughts.
It wouldn't do to have another world war before the zombies were even eliminated.
Blue Star could no longer withstand such a drain. The drastic decrease in human population meant it could not afford the harm caused by those with selfish desires.
At Lu Heng's instruction, Evan adjusted the equipment here to Lu Heng's desired state within a few days.
Lu Heng also now possessed a controller that could remotely control the locations covered by the satellite on Blue Star.
This would allow for control over who could use the satellite's permissions in the sky.
Of course, controlling only the satellite coverage area was not enough. To use satellite remote communication, one also needed to use the modified Blue Star mobile phones.
Lu Heng had many mobile phones in his space. After installing the small components specially modified by Evan on these phones, they could be used normally.
Lu Heng took a modified mobile phone and tested its effect against a regular mobile phone.
As expected, the unmodified phone was still just a brick. Apart from playing some built-in single-player games when it had power, its network-dependent functions could not be used.
"Then go back to your space and modify more phones. I'm going back now to distribute new communication tools to everyone."
"Can I go out and explore with you?"
Since being brought to this country by Lu Heng, Evan had never left Nameless City.
The satellite base station they came to this time was the second place it had landed in this country.
It wanted to scan the current surface conditions of this country to ascertain the whereabouts of the Senar aliens here.
If it could leave Nameless City alone, perhaps it would have a chance to find those Senar aliens.
As if sensing Evan's thoughts, or perhaps not entirely trusting Evan, Lu Heng did not agree to Evan's request.
"You should go back to your space and modify the phones. I need them when I get back. Modify more, I have plenty of phones in my space city."
Evan ultimately did not get its wish and was recalled to his space by Lu Heng.
Lu Heng then roamed the satellite base station again, reinforcing many areas.
This place not only needed to prevent zombies from returning to cause destruction but also to prevent humans from invading.
Lu Heng used his special metal ability to tightly encase many areas here.
Of course, it wasn't completely sealed off, but rather special metal cages were created to cover the entire area.
Unless they encountered a metal-element ability user with a higher level than him, no one would be able to break through the metal bars created by Lu Heng.
