They would wait a few more years until all zombies had evolved their psychic cores. Then, they would launch a full-scale sweep and harvest of zombies worldwide. The harvested zombie cores would be stored to prepare for their descendants' evolution and further advancements.
As for what would happen if both zombies and humans were gone, and only they remained?
They, of course, had a detailed plan. For example, they would spend a certain amount of time to completely clear the zombie virus from the environment. The ultimate version of the zombie virus, after modification, would not only consume the original zombie virus in the air but would also self-destruct within ten years after losing its human hosts.
In other words, even if they did nothing, after releasing the ultimate zombie virus and cleaning up all the zombies, giving the planet ten years to recover, the zombie virus would naturally perish.
After dealing with the zombie virus, they would retrieve the frozen human genetic material from the human doomsday hope vault, synthesize fertilized eggs, and recreate humanity. They would also educate these new humans.
From then on, they, the evolved ones, would be gods.
The newly created humans from fertilized eggs would be mere mortals, designed solely to serve them, the gods.
Should their psychic cores ever be completely depleted, they could always release the zombie virus stored in their secret bases again, creating more zombies and harvesting more cores. Thus, they would maintain their divine system of rule for generations to come.
Unquestionably, their actions and thoughts sent chills down Ding Yun's spine. They were no longer human; how were they any different from cannibals? They were truly anti-human, world-ending demons.
"How terrifying. Compared to them, what are those demonic cultivators who raze cities? Only world-ending great demons could be remotely compared to them. No, this matter absolutely cannot be ignored. However, dealing with it is incredibly tricky. Currently, I know of four relevant research institutes, and it's a question whether there are others that the artificial intelligence hasn't found. Furthermore, they possess destructive weapons. Even if I inform the entire world, it might be difficult to completely stop them. It could even tip them off, causing them to change locations or split into more hidden institutes. More importantly, we cannot ignore the risk of them going mad and prematurely spreading the ultimate zombie virus. This is not something I can solve alone; I must find allies. Nations and bases not involved in this plan are easy to find, but who can guarantee they don't crave immortality? If those from the Western Continent use this as a temptation to recruit them, things will become even more difficult. What to do? What to do?"
Amidst her indignation, Ding Yun paced her room with great anxiety, contemplating her next move. This matter was truly daunting. Either the participants in this plan and the ultimate zombie virus needed to be destroyed within a short timeframe, or a way to counter the zombie virus needed to be found to render the ultimate zombie virus ineffective. However, both options were extremely difficult. The former was problematic because the research institutes were scattered, possibly with hidden ones, making it hard to eliminate them all at once. If any were missed, they would hide even deeper and might even seek revenge. The latter was difficult because the zombie virus was not a typical virus but an evolutionary factor. It couldn't be resolved with conventional medicine or vaccines; it was a forced evolution. Unless humans evolved successfully beforehand.
At this thought, a spark ignited in Ding Yun's mind: what if humans could evolve beforehand? The zombie virus could only infect unevolved humans. If humans had already evolved, they couldn't be infected, no matter what. She possessed many gene-modification potion formulas; perhaps they could be useful. Perhaps humans modified by genes were considered successfully evolved. Furthermore, her grandparents had already achieved successful evolution, not like her, who used a golden finger and martial arts for evolution. Could the deactivated zombie viruses within her grandparents' bodies play a role akin to a vaccine, or could they serve as a basis for creating an evolutionary potion that required little energy and posed no danger?
Stemming from this idea, a multitude of new thoughts emerged in Ding Yun's mind. However, realizing these ideas on her own would undoubtedly take a long time and require cooperation for experiments. Therefore, after further consideration, Ding Yun finally decided to contact the domestic bases. Lacking direct channels, contacting them directly through artificial intelligence felt abrupt and impolite. So, she chose to visit the director of the Sunflower Base first, bringing some important documents, hoping to use him as a hub and bridge to connect with other reliable domestic bases.
Using the token provided by Base Director Zhao Louhai, Ding Yun easily entered his office and received a warm welcome, complete with fruits and drinks, which was quite a luxury at this time. "Ah, the drink just expired a month ago. I drank it, and it's still fine. If you mind, you don't have to drink it. Please, have a seat, don't be so formal. You are our base's benefactor now. The supplies you brought this morning are still being categorized and inventoried. Once that's done, we'll distribute some to everyone in the base. Your contributions will be acknowledged..."
Ding Yun had important matters to discuss and immediately interrupted him without politeness, saying sternly, "Base Director, I have something major to tell you, something that concerns the survival of humanity. This is information that our organization obtained at the cost of many lives. We initially planned to make it public, but we feared it would tip off those involved and cause them to accelerate their world-ending plans. Therefore, our organization wants me to represent them and cooperate with compatible domestic bases. I know you have many questions. The detailed information is here; you can examine it carefully. We can talk after you've read it. I can guarantee that all the information within is true and not fabricated."
After speaking, Ding Yun didn't wait for Zhao Louhai to ask any questions and thrust her tablet into his hands, letting him review the contents himself. The tablet contained all the crucial information Ding Yun had streamlined, including the original Western continent documents, translations done by artificial intelligence, and even some pictures and videos. Ding Yun specifically cautioned him: "Before you look at the pictures and videos inside, you must be mentally prepared. They are very cruel. Calling them demons is an insult to demons. You don't have a heart condition, do you? In any case, please be prepared."
