The wails and roars of zombies echoed throughout the city.
Lu Heng, within his spatial dimension, disabled the sound permissions. He didn't want to constantly listen to the cacophony of zombies outside.
Lu Heng watched the zombies outside engage in their own battles for a while. Their fighting methods were still chaotic.
However, facing fellow creatures that couldn't be easily killed, the zombies' mindless tactics proved ineffective.
Unless their brains were pierced, zombies wouldn't die. Even if they were dismembered by their companions, they could still writhe on the ground.
Only those zombies with innate area-of-effect abilities could deal with their kin more swiftly.
Especially fire-elemental zombies, whose indiscriminate damage effects were particularly evident at this moment.
After watching for a bit, Lu Heng returned downstairs. Evan was very quiet here.
But it wasn't idle either, constantly tinkering with some items Lu Heng had given it.
Lu Heng walked over to Evan, observing the items Evan had arranged in the open space.
He casually picked one up and examined it.
"What is this for?"
"I've improved it. This can be used to heal you humans."
Lu Heng then looked closely. Indeed, it was a medical instrument Lu Heng had brought from the space city.
This device was originally intended for treating the Sennar, but humans and Sennar had different genes, so Lu Heng hadn't dared to use it on humans.
Unexpectedly, Evan had modified it, and it could now repair physical injuries for humans.
"However, it cannot heal wounds caused by zombies. Zombies carry viruses, and corresponding antibodies are still needed."
These alien devices only served to suture and restore injuries. But zombie infections in humans were caused by viruses, and such restorative equipment couldn't directly fix viruses.
"Yes, it seems these devices aren't omnipotent."
"Of course, nothing is absolute."
Evan continued to manipulate the items in front of it, its fingers moving incessantly between the metal substances, sparks occasionally flying.
"You've modified the welding function."
Lu Heng was quite curious. Seeing the sparks fly, he observed Evan's fingers.
These fingers likely weren't its original form; they had also been modified by Evan itself.
"You seem to enjoy working on these things?"
Seeing Evan diligently busy, Lu Heng couldn't help but speak.
This Evan was truly intelligent. After developing emotions, it became very enthusiastic about modifying equipment.
It would occasionally modify small items, not just simple welding, but more often applying technologies far beyond human civilization to human-made devices.
"By the way, this communicator, can you replicate it?"
Lu Heng took out the communicator Bola had given him. This device had the function of unlocking restrictions on alien rooms, and Lu Heng wanted to see if Evan could replicate a few.
Evan took the communicator. Suddenly, a thin wire extended from its middle finger, and the metal wire quickly entered the communicator.
"Yes, did the Sennar give you this one too?"
"Yes, but they only gave me one. Do your space cities have these things?"
"No, only spaceships are equipped with these. When living within the cities, the Sennar don't use these."
So, this communicator was merely for the Sennar's convenience when traveling. In their main bases, there were high-tech communication devices everywhere, so such single communicators were not needed in cities.
"It's a bit of a shame."
It was likely that Evan's replication wouldn't be as precise. After all, resources on Blue Star were limited, making it difficult for it to create items of this quality.
"Your place is very interesting."
"?"
Lu Heng didn't understand the meaning of Evan's sudden remark.
"After I take things from here, new items always replenish the original positions."
Oh, so that's what it was talking about.
This Evan was indeed smart, observing even this detail.
"Yes, isn't that good? You don't have to worry about running out of anything you need."
"Indeed. How do you do it?"
Lu Heng shrugged. "Honestly, I'm not sure how it's done."
He glanced at the spatial connection points downstairs, recalling Bona's space.
These two types of spatial traversal seemed somewhat similar. Was it also because aliens came to Blue Star that he was reborn and gained this space?
"Have you been to those places?"
Lu Heng pointed to the end of the road not far away.
"I have. What is that?"
"You don't know either?"
"I don't know."
Actually, when Evan first controlled the two robots Lu Heng brought back from the space city and successfully exchanged mechanical bodies, it had discovered them while wandering the city. However, at that time, it was still looking for an exit from this space.
These city road exits were arranged together and all gathered within the urban area, so it hadn't paid too much attention at the time.
Although it had a lot of human knowledge in its mind, a high-level robot that never took humans seriously had never analyzed the rules of the human world.
It had searched for a long time in this space, these few peculiar places.
It had touched them, but when it touched the barrier, it felt like a wall.
There was no difference from touching other buildings.
"This is similar to the barrier outside the space created by the Sennar."
"What space?" Evan looked at Lu Heng in confusion.
"It's quite similar to this. You can pass through with this communicator, and inside is another world."
Before Lu Heng could say anything more, Evan looked at the communicator in its hand and unhesitatingly walked towards one of the barriers.
But Evan didn't pass through the barrier. When its metal hand touched the barrier, the sensation was the same as before.
Lu Heng, watching from the side, raised an eyebrow.
It seemed this Evan was still a bit disobedient. As soon as he mentioned that the communicator could traverse alien spatial barriers, it eagerly tried.
Did it not consider him present?
With a wave of Lu Heng's hand, the communicator that was in Evan's hand returned to Lu Heng.
"It seems you can't pass through."
However, what surprised Lu Heng was why this Evan didn't know about the space created by the Sennar.
"You can pass through?"
"Yes, I'll demonstrate for you."
Lu Heng walked to an open space and stepped through.
From the outside, Evan watched Lu Heng disappear before its eyes.
It was similar to how Lu Heng had suddenly disappeared and reappeared in front of it on previous occasions.
A short while later, Lu Heng reappeared.
Evan also clearly observed the phenomenon of Lu Heng's body passing through the barrier.
