Chen Dong and his team intensified their research on the zombie virus antibody.
The items Lu Heng brought back were far more valuable than simply having ordinary zombies for research.
They extracted numerous blood samples from rats that consumed zombie meat without being infected, and from a zombie infant.
This time, they even brought a living specimen, someone who had experimented on the zombie virus and turned into a grotesque, living dead.
After a month of continuous experimental comparisons, Chen Dong finally presented Lu Heng with a satisfactory answer.
"Brother Lu, this is the agent Chen Dong and his team just developed. After injection, there's a 90% chance for non-infected organisms to resist the zombie virus, meaning they won't be assimilated into zombies if bitten or scratched again."
Lin Yu handed Lu Heng a vial containing an orange-yellow liquid.
"What did they use for the experiments?" Lu Heng asked, taking the vial.
"They experimented on animals. We've been raising quite a few mutated animals as livestock, haven't we? They tested dozens of them. Without exception, after injecting this agent, none of those animals became zombies."
"Mm, but it's best not to let people eat that meat anymore. Dispose of it all."
The zombie virus was still too bizarre. Even with successful experiments, if the animals showed no signs of mutation, their meat might still infect humans if consumed.
"Yes, I already gave instructions during the experiments. All animals used in testing were eventually dissected and incinerated."
Lu Heng nodded upon hearing this. "We should find some people to test this on first, and then use it on the people of Nameless City."
Although creating so many high-level ability users didn't cost Lu Heng much in terms of magic crystals, these individuals had been tempered through numerous battles, making them incomparable to newly promoted ability users.
Lu Heng needed to ensure the combat strength of Nameless City remained unaffected. If experiments were to be conducted, there were plenty of ordinary people and those villainous ability users available.
After so long in the apocalypse, besides those who couldn't evolve due to their own reasons, there were also many who hadn't evolved and couldn't face zombies, content to hide in the havens created by ability users.
Lu Heng didn't mind using these people to contribute to the survival of more people in this world.
Lin Yu also agreed with Lu Heng's perspective. He had once been a weak and helpless youth, but that was by force.
He knew very well that this world was no longer the peaceful one it once was, and without sufficient strength, survival was impossible.
Therefore, he had been rigorously demanding of himself, from improving his abilities and personally killing zombies to later learning to manage a city.
These were things a high school student could never have imagined before.
"Let's start experimenting, but this agent needs further strengthening to achieve one hundred percent effectiveness."
"Yes, but the experimental materials require the blood of the Senar people. The bottle you brought back last time might not be enough."
The creatures Lu Heng brought back for research were almost all live specimens, providing a continuous stream of samples for the research center.
However, for the Senar people's blood, Lu Heng had only brought back a small bottle before.
It seemed he would have to make another trip to Luocheng.
But even if he obtained more Senar blood, it would be like a drop in the ocean.
Moreover, Lu Heng wasn't entirely confident he could use the same method to draw blood from Borna again this time.
"You and your two robots should patrol the city more often, especially around the research center. Give those people a morale boost."
Lu Heng had previously considered taking Evan to the research center to show them the extent of technological civilization's development, thereby motivating scientists to accelerate their research in their respective fields.
However, considering safety concerns, he decided it would be better to have Lin Yu lead the two non-sentient robots in promotional activities within the city.
Apart from providing information and answering questions for the researchers, it was better for Evan to have minimal contact with people.
To prevent Evan from getting bored in the space, Lu Heng placed the spaceship it had in Country Y within the space.
This was a form of benefit for Evan, at least showing it a measure of Lu Heng's sincerity.
As for whether this spaceship could communicate with the outside of the space, or if it could perform spatial jumps within the space, Lu Heng wasn't worried. He had a feeling that his space's shielding power was under his control, and without his permission, Evan would be confined within the space.
Therefore, Evan had been very well-behaved in the space this month, almost always busy inside the spaceship.
Lu Heng had entered a few times to check on it, and Evan hadn't avoided him, explaining what it was doing while making repairs.
It even said that once the spaceship was repaired, it could use it to return to Kandu.
Lu Heng smiled noncommittally, not responding to Evan's probing.
His thoughts returning, Lu Heng handed the agent in his hand to Lin Yu.
He didn't need this item for now. Perhaps after millions of people had been tested and the agent's stability was confirmed, he would consider using it on himself.
With his various contracted pets and the life-saving measure of his space, he wouldn't need the agent anytime soon.
"I'll find time to go to Luocheng. Do you want to come with me and take a look?"
Lin Yu had been to Luocheng before, but he hadn't had direct contact with aliens. Lu Heng also wanted to take Lin Yu to broaden his horizons.
These aliens planned to live on Blue Star long-term, and there would inevitably be contact with humans in the future. Therefore, Lu Heng wanted Lin Yu to interact with them sooner rather than later.
"Will they welcome me?"
It wasn't that Lin Yu lacked confidence; after all, they weren't human, and he worried that aliens might be xenophobic and dislike too much human contact.
"It should be fine. How about I call them and ask?"
Bora had been under confinement the last time, and Lu Heng hadn't been able to contact her. Bora also hadn't contacted him since then. This was a good opportunity to inquire about Bora's situation.
Lin Yu nodded in agreement. "Then please ask. If they allow it, I would indeed like to go and see."
From Lu Heng's descriptions alone, Lin Yu was also very eager to know about the world of the Senar people.
He heard that they had built a small world on Blue Star, with architectural styles similar to those on Senar.
Lu Heng took out the alien communicator and pressed the connection method Bora had previously told him.
Soon, Bora answered.
"Lu Heng, what is it?"
Bora's holographic image appeared above the communicator. Looking at the background, Bora was currently in her own room.
"Has Bora been released? I haven't received any news from her for a while."
"Yes, I've been a bit busy lately and forgot to tell you.
She was released not long after you left last time."
Perhaps because their population was too small, they had relaxed some restrictions on Senar people like Bora who could transform into females.
However, whether this was the specific reason was merely Lu Heng's own speculation.
