Evan scanned and recorded the moment Lu Heng traversed space.
Its processor was performing multi-faceted analysis, but without knowledge in this field, Evan ultimately couldn't understand why the "wall" Lu Heng passed through was impenetrable to itself.
Evan watched Lu Heng reappear. "I don't understand. This is clearly a wall to me; how did you manage to pass through it?"
"Actually, I don't understand it either. After my level is increased, I will gradually unlock the authority to traverse these 'walls'."
"These... you can't pass through all of them yet?"
"Yes, there's only the last place left."
Lu Heng pointed to the space he currently couldn't penetrate.
"You just said that increasing your level would unlock it. Then why haven't you leveled up yet?"
"I'm not sure exactly how many levels I need to reach, but the crystals obtained from the zombies outside can no longer increase my level."
"Then let the zombies level up, and you go kill them."
Lu Heng naturally understood this simple logic.
But the problem was that the crystals required to unlock the last space were from zombies of level ten or higher.
Not to mention that the current zombie levels were generally not high, with naturally grown zombies at this stage being around level six.
To obtain higher-level zombie crystals, he would have to, as before, corral zombies and let them fight each other to level up.
However, Lu Heng always found it difficult to do such things calmly.
Furthermore, to cultivate high-level zombies, he would need to control these zombies and constantly make them fight.
But if other humans saw him taming zombies, it might attract unnecessary condemnation for Wuming City.
He was no longer living alone in this world. Lin Yu and the others by his side were his ties.
Seeing Lu Heng remain silent, Evan didn't understand, but knowing that this space had a "wall" to exit, its mind began to race.
It had always wanted to avoid being controlled by these cellular beings. Before it had its own consciousness, it was forcibly enslaved by the Senal aliens.
But now, it had its own goals, and it didn't want to be controlled by the human beings around it anymore.
Although it had reached some agreements with Lu Heng, how could that be more important than the grand plan in its mind?
It wanted to leave this place and return to the world of robots, where it would create a world without cellular beings.
Each lost in their own thoughts, silence fell upon the space for a moment.
Lu Heng couldn't read the robot's inner thoughts and was completely unaware of Evan's renewed intentions.
Evan, meanwhile, lowered its head and fiddled with the machinery before it, but a part of its brain was still constantly calculating feasible methods.
"Modify a few more of these for me."
Finally, Lu Heng broke the silence, taking out dozens more Senal alien medical devices.
Evan shouldn't take too long to modify these.
Evan glanced silently at the pile of Senal alien items that had appeared on the ground, further confirming Lu Heng's idea that he could directly go to the space city.
Therefore, one of these three "walls" must lead directly to the space city.
Sensing Lu Heng's departure, Evan put down the items in its hands and began to scrutinize the three spaces.
Lu Heng had said that these three walls were very similar to the spaces created by the Senal aliens.
But it had no information about such spaces in its mind.
Was it that the Senal aliens, to guard against robots, had not inputted this information into their factory settings?
Then it needed to find a way to follow Lu Heng out and see the Senal aliens' spaces on Blue Star.
It needed to find a way to obtain information data about spaces from there.
As for how to avoid being controlled by the Senal aliens again, it could discuss that with Lu Heng.
Evan could sense that Lu Heng still needed to use it, so Lu Heng wouldn't give up on it until his objective was achieved.
After a long time observing the entrance and exit of the space, Evan found no clues and returned to busy itself with the new batch of medical devices Lu Heng had brought.
If it wanted to talk to Lu Heng, it first had to complete the tasks Lu Heng had assigned.
...
After leaving the space, Lu Heng went to find Lin Yu again.
Taking out the modified medical device from Evan, Lu Heng handed it to Lin Yu. "Have someone try this out for treating external injuries."
Lin Yu took the medical device and looked at it, not immediately understanding how it treated external injuries.
However, judging by the material, it should be an item Lu Heng had obtained from aliens.
"Is this effective for humans?"
"Have someone try it. It should be useful; it's been modified."
"Have Chen Dong and the others figured out how to modify alien items?"
Lin Yu knew that Lu Heng had found an intelligent robot to modify Blue Star's items.
"No, the robot modified it itself. If it's feasible, I've asked it to modify a batch. From now on, each small team should be equipped with at least one."
"Alright, I'll find someone to try it."
"Yes, but don't try it on our own people first."
It wasn't that Lu Heng didn't trust Evan, but the technology of these items was too advanced, and Lu Heng wasn't sure if there would be any side effects when used on humans.
Lin Yu nodded and was about to leave with the medical device when Lu Heng quickly stopped him. "Aren't you going to ask how to use it?"
Although the usage of these alien items was simple, without someone to explain, humans would indeed take some effort to figure it out.
Lin Yu scratched his head sheepishly. "Haha, I forgot. I was too excited."
Lu Heng explained the usage of the medical device to Lin Yu, and only then did Lin Yu excitedly leave with the item.
For humans, this was a good item. Once it was available, humans would no longer suffer from injuries.
Of course, it couldn't resist the zombie virus, and it couldn't heal wounds caused by zombies, which was a bit regrettable.
Soon, Lin Yu returned and informed Lu Heng of the verification results.
It was indeed capable of treating any external injury, even fractures could be completely healed by this device.
Even severed limbs, as long as the damage was not comminuted, could be healed by this device.
"Hahaha, this thing is truly amazing, Brother Lu. The minds of aliens are truly incredible; they can even create such things."
"You haven't seen their world. It's truly like being in a science fiction movie. Whatever you can imagine, it's everywhere."
"I really want to see it."
Lin Yu also yearned for the world Lu Heng described and couldn't help but envy Lu Heng's ability to traverse multiple worlds.
Different worlds had different people and different things.
What kind of experience would that be?
