Lu Heng marked a region on the map, identifying a suitable area.
However, most of the cities controlled by these zombies had bases of human survivors interspersed.
But Lu Heng could not allow these zombies to cross over into areas where humans lived.
Therefore, these newly formed zombie armies had to be eliminated within their original territories.
Then, Lu Heng would take Sun Qiang to a new area, allowing Sun Qiang to reassemble a team of advanced zombies.
This way, Lu Heng would have a steady supply of high-level crystals, and the zombies could kill each other, reducing unnecessary losses during battles between humans and zombies.
Lu Heng located Sun Qiang using a locator. Sun Qiang's level had not increased; it remained at level ten.
Sensing Lin Xue's information, Sun Qiang commanded its zombie army to gather in an open space, while it went to find Lin Xue.
It knew that Lin Xue was with Lu Heng, and finding Lin Xue meant finding Lu Heng.
Soon, Sun Qiang found Lu Heng on the rooftop of a building.
"You've arrived," Sun Qiang first glanced at Lin Xue before turning its 'gaze' to Lu Heng.
"Yes, I've seen it. You've done a good job here, clearing out zombies thoroughly wherever you've passed."
Lu Heng had meticulously searched along the way. Through Lin Xue's perception, he knew that the areas Sun Qiang and its group had traversed were completely devoid of any zombies.
Using zombies to clear zombies, and doing so cleanly.
After all, the pressure exerted by zombies of different levels was evident. Under the command of advanced zombies, lower-level zombies dared not hide anywhere.
This way, the zombie army controlled by Sun Qiang could eliminate all zombies that responded to the summons.
Sun Qiang showed no emotion towards Lu Heng's praise; it seemed indifferent to the elimination of zombies.
"The zombies in this city have also been completely wiped out. Should we continue advancing forward?"
Lu Heng had previously planned a route for Sun Qiang. Although the zombies had regained intelligence, they could not fully recover the intelligence they possessed as humans. They were unable to correctly use human positioning tools.
Therefore, Lu Heng could only point Sun Qiang in a direction, instructing it to advance towards the sunrise each morning.
However, this was easy for Sun Qiang to discern, having regained its sight.
Under Sun Qiang's leadership, they had not gone in the wrong direction.
"No need. Those zombies you have, I'll have Lin Xue handle them."
Allowing the higher-level Lin Xue to control these advanced zombies to fight each other, thereby concentrating higher-level zombies.
This way, Lu Heng could obtain some high-level crystals by killing these concentrated higher-level zombies.
With these high-level crystals, he could also quickly open the last barrier in his space.
Following this, Sun Qiang remained by Lu Heng's side. The zombies, which were no longer of much use, began to slaughter each other upon sensing the control of even more terrifying, advanced zombies.
Shortly thereafter, the thousands of advanced zombies were condensed into a few dozen level nine zombies.
Lu Heng personally took action and eliminated all these concentrated zombies.
Finally, Lu Heng, holding dozens of level nine crystals, took Sun Qiang to a new area for slaughter.
In a new city, Sun Qiang once again assembled a batch of usable zombie soldiers and began the same operation as before.
After Lu Heng took Sun Qiang to the new region, he returned to his space to begin absorbing the crystals.
However, even after absorbing this batch of crystals, the last barrier in his space did not open.
Perhaps it was still not enough.
Lu Heng went to the open space in front of his spatial apartment. Evan was still tinkering with something.
A pile of items was stacked on the ground in front of it, mostly electronic products.
Seeing Lu Heng appear, Evan stopped what it was doing and said to Lu Heng, "Long time no see."
"Yes, have you researched anything new?"
"Still old items, nothing new. There are too few usable parts here; I can't assemble many things."
"What do you need, and what for?"
"Aren't you interested in alien communicators? If I can create a communicator suitable for human use, wouldn't that be of great help to you?"
"That would be wonderful. Currently, because the satellite base stations on Blue Star have been damaged, the entire world is in a state of inability to communicate over long distances. If you can create this, it would greatly facilitate human communication."
"But I lack parts, and one Senar Star communicator can only be modified into one suitable for human use."
Therefore, it would take some time to restore normal global communication.
Lu Heng looked at the smartphone in his hand and asked Evan, "If I take you to the satellite base stations on Blue Star, can you help repair them?"
Although the satellite base stations on Blue Star were destroyed, the artificial satellites flying in space were still operating normally.
In fact, some humans had tried to repair the satellite base stations on Blue Star, but even after repairs, they were soon destroyed by zombies again.
Lu Heng wanted Evan to use the technology of the Senar Star people to create a satellite base station that could not be destroyed by zombies.
After all, any item from Senar Star would not be destroyed by zombies; instead, they would gather around it, providing temporary protection.
"I need to see it to know."
"I can take you, but you must behave. If I discover you trying to escape, I will capture you and confine you forever in this space from which you cannot leave."
"No, I still want to return to our space city."
Evan was not lying this time; it truly desired for Lu Heng to take it back to the space city.
Its wish was to build a world exclusively for robots there.
Having received Evan's verbal assurance, Lu Heng did not disbelieve it. He also knew that Evan's greatest aspiration was to return to the space city.
However, Evan was hiding something from Lu Heng. It also wanted to contact the Senar Star people on Blue Star to understand how they created their spatial barriers.
In its opinion, these were merely created through technological means.
As a robot, its strongest abilities were calculation and analysis.
If it could access those, perhaps it could research it itself.
Thus, it would not be controlled by Lu Heng, a human, and return to the space city through Lu Heng's space.
Opening the data on his computer, Lu Heng found satellite images recorded before the apocalypse.
Soon, he identified several satellite base stations on this continent.
With a thought, Lu Heng first left his space. Once he reached the location of the satellite base station, he would release Evan.
