"Let's go." Song Xia forced herself to calm down, and kept stuffing food into her mouth to do so.

Meanwhile, the system Xiaoling was extremely excited: "Xiaxia, do you know what you found?"

"What? It's related to zombies?"

"There is a connection, but this thing is of greater value to humans for physical research than for chemical research."

Explain clearly.

"This is a black stone. It has been recorded in the scientific literature of Zero World. Black stones are formed by the collision of stars and have a certain probability of connecting to black holes. In other words, if humans thoroughly study black stones, it is possible to go to other star systems to complete interstellar travel."

The name was simple and straightforward. Song Xia's mind stirred slightly. The Earth's environment was deteriorating year by year. If they could find a habitable planet again, that would be the best thing.

"Back then, Zero World was able to rule one galaxy after another only after discovering the Black Stone. However, it took the intelligent beings of Zero World a full three hundred years from discovery to crossing the black hole."

"Given its advanced technology and dominance over so many star systems, how could Zero World have become so lifeless?"

The system, Xiao Ling, paused for a moment: "Xia Xia, the birth of life is miraculous, and the dissipation of life is sometimes beyond our control. It's not that Zero World doesn't want new life to be born, but that it can't. It can't be done no matter what it tries. So the last remaining intelligent beings in Zero World can't understand why some creatures don't cherish life, especially humans, who are the least life-loving intelligent beings they know. Do you know that Zero World even has an entire planet built specifically for raising offspring? It has the best environment for raising them. Unfortunately, Zero World never got to see a single offspring."

Listening to Xiaoling's sorrowful tone, Song Xia could almost see the despair, helplessness, loneliness, and emptiness in her voice.

Let alone the lifeless Zero World, even at the very beginning of the apocalypse, some people, even though they were not infected, still felt hopeless and chose to commit suicide.

This shows that humans are indeed quite fragile and quite prone to giving up on life.

"The black stone is so powerful, but Zile's research isn't in astrophysics. If we give it to someone else..." Song Xia felt a surge of unease. It was too unsafe. "However, the predecessors of Zero World have been researching it for three hundred years. It should be feasible to use this time to cultivate talents without ulterior motives!"

"Xiaxia, I have some research papers from Zero World. If we can find other materials, we won't have to spend another three hundred years. Zile is still young and so smart. We can try a different research direction."

"Want to give it a try?" Song Xia looked at Zi Le, wondering if it would be too tiring.

She pursed her lips. Let's wait and see. Why put the burden of the world on little Zile's shoulders? Too much pressure will stunt his growth. Does this mean that without Zile, none of these survivors can survive?

"Don't you Zero Worlds always believe in treating cubs kindly? Zile is still so young, we can take care of his studies later."

The system was speechless for a moment, after all, that was indeed the case.

"Let me ask you one more question: what would happen if this black stone fell into the hands of zombies?"

"I don't know." Xiaoling shook her head sincerely. "There are no zombies in Zero World, and before you were reborn, no one in this world discovered this black stone. In the previous life, without you, the situation in the apocalypse was much more serious. Zombies, mutated animals, and plants constantly squeezed the living space of the survivors. The leaders of each base even started a war for power. In the end, only a few humans were left to eke out a living."

Xiao Ling didn't expect Song Xia and the others to change the world so much at first. But then again, changes usually have a chain reaction. At such a critical moment, the good will get better and the bad will get worse.

Without Song Xia controlling the zombies, how could the White Tiger Base have smoothly weathered wave after wave of zombies? With the contradictions and conflicts within the White Tiger Base suppressed, other bases temporarily put aside their internal struggles in order not to be outdone.

There's also Ziqi's exotic plant. I remember in my previous life there was an exotic plant that dominated a territory. No matter how I compare them, that exotic plant seems to follow Ziqi's plant. In this life, it has not caused harm, but has benefited the survivors.

Then there's Zile. Without Zile's antiviral drug, more superhumans would have died from the zombie virus in battle after battle, but now there are no innocent casualties.

Once things improve, it's not just a simple addition, but a multiplication.

It wouldn't be an exaggeration to say that Song Xia and her little ones saved the entire world.

Song Xia suppressed her impatience and talked to Xiao Ling, then suddenly looked in one direction and sat up straight. Song Zile's nerves also tensed up at the same time.

"What's wrong?" Lao Hei and Lao Luo became alert. How long had it been since they'd felt such a tense atmosphere? What on earth was coming?

"Is that a zombie?"

Before the question was even out of his mouth, Song Xia had already opened the car door and run over. The two of them clashed, creating a tremendous commotion.

This was the first time Lao Luo and Lao Hei had seen Song Xia fight so badly. It was even more difficult than when they fought the giant mutated zombie. With one punch from that monster, Song Xia was sent flying more than ten meters away.

Song Zile looked at the box in his hand and knew that the zombie had come for what was inside.

The other superhumans in the convoy were terrified, because in the eyes of the survivors in the new district, Song Xia was nothing short of a god. They had all firmly believed that Song Xia was the most powerful person in the world, but now, their god was no match for this zombie of unknown origin.

Over the past three years, information exchange between the various bases has been frequent, including records of where dangers are. However, this zombie had never heard a single word about it before. What they feared was not just this, but the fear that there were more unknown dangers that they were unaware of.

If even Song Xia can't withstand these dangers, who else has the ability to step in?

"What do we do now?"

"What can we do? If Sister Song is no match for us, do you think we can escape?"

"Can anyone tell me how it suddenly appeared?"

“This.” Song Zile held the box, her expression hesitant.

Old Hei took a deep breath: "We can't hand it over. What if it uses this to evolve into something even more powerful?"

"Then who can defeat him now?"

Song Zile got out of the car and walked towards his mother's direction. Since the zombie was so eager, would it also have an effect on his mother?

What is he trying to do?

"Aren't you going to stop it?"

Lao Luo and Lao Hei shook their heads. Logically speaking, Song Xia was also a zombie. If this thing was really useful to zombies, then it would be useful to Song Xia as well.

I just don't know what its function is.
