Lu Heng kept looking between Lin Xue and Bola.
Lu Heng remembered that Bola and their group arrived on Blue Star in March 2041, though the exact date wasn't specified by Bona at the time.
The terrifying event of humans turning into zombies and the global outbreak of zombie mutations occurred on April 1, 2041.
Given the zombies' craving for living creatures, they shouldn't have refrained from attacking extraterrestrial beings. After all, Bola and the others were living organisms.
Yet, not only were the zombies not attacking Bola and their kind, but they were also showing a strange eagerness towards them.
Could there be a connection between these two phenomena?
Lu Heng, seeing that Lin Xue was relatively obedient, didn't dwell on it further and recalled her back into his space.
"Huh? Where did that zombie girl go?"
Bola, noticing Lin Xue's sudden disappearance, floated to where she had been standing.
"I put her away. She has a contract with me, so I can store her."
"Where did you put her?"
"Well, she's become a mark on my skin." Lu Heng didn't disclose the details of his space to Bola; he always kept some of his trump cards hidden.
"There's such a miraculous thing?" Bola looked at Lu Heng with surprise, her face filled with curiosity.
Although Lu Heng couldn't precisely decipher the expressions of aliens, his intuition told him that Bola was very eager to see what his mark looked like.
When Lu Heng contracted animals later, he didn't pay much attention to where the tattoo-like marks appeared.
Therefore, he didn't know where Lin Xue's tattoo was.
"Ahem! I also find it a bit strange. You saw earlier that the zombies not only didn't reject you but seemed to want to get closer. So, you can't go to human settlements for now; you'll attract zombies to humans."
"Then I'll wait. However, coming out this time, I've discovered that your Blue Star is quite beautiful, with green plants everywhere."
The location they were in was the former outskirts, with fewer buildings. The plants that had grown wildly outside were now even more lush than before.
"Right, do you have any operation manuals or anything for your robots? Like an instruction manual."
Remembering the secrets of the robot in his space, Lu Heng couldn't help but change the subject, hoping to extract some methods for operating the robots.
He wondered if Bola would share the information.
"You're so interested in our robots?"
Bola was somewhat curious. This wasn't the first time Lu Heng had inquired about robots. She had lived for many years, and although she was still considered a minor in the alien world, she had seen quite a lot.
"It's just that your robots are too powerful. Sometimes, as soon as we meet, we're attacked. It's too dangerous."
"Yes, but the information Bona gave you earlier had some explanations. Isn't that enough?"
"That's too superficial, I've already read it.
Moreover, if you want to live on Blue Star in the future, you'll always need to establish some connections with humans. I believe that in the future world, I can indeed represent humanity and speak with you.
Why don't you share some information that would be helpful to humans first?"
"I can't make that decision. You should discuss it with Bona; he is our leader."
Bola didn't directly give Lu Heng what he wanted.
Since Bola couldn't decide, there was no point in lingering with her.
"Then you should head back. Try not to go to places with human activity on your way. If all humans on Blue Star are killed by zombies, this planet might become very uninteresting."
The reason humans held a dominant position among all life forms on Blue Star was largely due to their ability to think and act. If this balance were broken, Blue Star would truly revert to a primitive state.
Perhaps after many years, other creatures would evolve and become the dominant species, replacing humans, but Blue Star would have to fall silent again for a long time.
"Okay, I'll head back then. It's a shame I couldn't visit any human cities this time."
"You can wait a bit longer. Perhaps Bona will have some results soon."
Watching Bola leave, Lu Heng put away the metal fence. This metal could be reused later. Since it had already been made, there was no need to waste it.
Immediately after, he returned to his space from where he was. The experiment with Lin Xue earlier had made him think of another problem.
He had collected some of Lin Xue's tissue samples from his space. Lin Xue could recover from her wounds on her own, which was not troublesome.
After taking the samples, he also took out some samples from the alien corpses stored in his space.
Then, he performed gene testing on both sets of samples.
Finally, Lu Heng, holding the two gene reports, was stunned.
There was indeed some connection between zombies and aliens. To ensure the data wasn't inaccurate,
Lu Heng found other alien corpses in his space and conducted two more gene tests.
He also extracted tissue from two ordinary zombies he had killed in the wild.
However, the test results were the same as before.
Both zombies and alien creatures had 24 pairs of chromosomes.
Logically, zombies were formed when humans were infected by some unknown virus and mutated into zombies.
Their basic bodies were human bodies, and the number of chromosomes in their genes should not have changed.
But why the mutation? Could it be that the virus brought by aliens infected some humans?
Lu Heng also drew some of his own blood for testing. It showed the chromosomes of a human ability user, unchanged.
Could it be that humans turning into zombies was indeed caused by these aliens' virus?
Did the aliens bring some substance that could alter Blue Star's biological evolution?
Lu Heng clenched the reports in his hand. If the aliens had interfered with Blue Star's biological evolution process,
and these aliens were now staying on Blue Star to live alongside humans and other creatures,
what other impacts might they have on humans and other life forms in the future?
However, humans were currently unable to change the aliens' intention to settle on Blue Star, nor could they drive them away or kill them.
Under the aliens' technological strength and the multiple crises of zombies and mutated animals, humanity was truly in a passive state.
But there were some things Lu Heng couldn't control at the moment.
Putting his thoughts aside, Lu Heng decided to return to Nameless City first. He didn't know what impact Bola's visit would have on the survivor bases along the way.
Fortunately, before leaving, Lu Heng had instructed Lin Yu, and this would also be an opportunity to see how Nameless City handled emergency situations.
Soon, Lu Heng flew back to Nameless City. He returned riding the eagle-beaked beast. As long as the existence of aliens on Blue Star was not widely known, Lu Heng didn't want to use too many alien items.
