The bullets were used up, but simply engaging in melee combat with the zombies infected with the virus would only lead to a continuous rise in soldier casualties. There was no other way, as the combat power of individuals after being infected with the zombie virus was simply too high.

The soldiers could only resort to simple backstabs and traps – dishonorable methods of ambush – to fight them.

As for the crystal cores within the zombies' bodies, the researchers, after various tests, found them completely unusable. Could immense power change a person's physique? But it was often accompanied by madness, mutation, and becoming a new, thinking zombie.

This still couldn't create a strong defense for the remaining humans.

Thus, true human experimentation began. Continuously modifying, optimizing, and adding the gene chains of mutated zombies meant constantly stacking quantities. If it failed, they were killed; if it succeeded, they continued to cultivate, adding new DNA fragments.

Under these circumstances, humans truly had the power to begin fighting the zombies. It was also during that period that these modified bodies were raised as pets, or humanity was evolved into that race.

To gain their own power boost.

The researchers initially only avoided participating in the other faction's experiments, but soon, the issue of resource contention arose. The scarcity of samples simply couldn't support both sides operating simultaneously, to the extent that both sides had experimental subjects go missing, only to find the zombie corpses appearing at the laboratory entrance the next morning.

And it escalated.

Until… the true mutation began, a creature that humans simply couldn't fight!

Traditional chemical energy weapons were like rattles played by children in front of those enormous mutated creatures, only making a noise.

Humans were forced to move, to the underground, to the air.

Until new progress was made in the research of the meteorite core. Injecting biological energy into it could tear space, which was the so-called other world. After testing, the experimental white mice successfully grew for about a week on the other side and did not undergo any mutations.

The entry of real people was put on the agenda. The natives who were invaded and oppressed ultimately turned their butcher knives towards the weaker humans.

Humans in the other world were powerless to resist the power beyond scientific explanation, until they were occupied. Thus, the natives successfully survived for a period of time with such support.

Some nostalgic scientists and researchers built Dawn in space and transported the meteorite core to the sky together.

And those researchers who only wanted to live stayed in the other world, until… the zombie virus broke out in the other world! Only the intensity and the speed of mutation were very slow. The first version of the vaccine could successfully block the spread of the virus.

But soon new problems arose. Even if the evolution was slow, it still broke the original idea of ​​these people who escaped reality, so the research of that year was put back on the agenda.

It was just that without the support of the main world, it was difficult for them to reach the height of that year again in a short time. Many basic resources could not be solved in time.

Soon, the era of behemoths in the other world arrived, which is the current situation. The so-called humans have almost become extinct again, and it is impossible to tell which side is the native of the main world and which side is the immigrant of the other world.

The two sides do not know each other, they just want to survive. After the matter of the other world, Dawn also launched the so-called Dawn Project, which is the Sweeper Project.

"Well, the things in the memory are quite comprehensive, but I don't know what the so-called Dawn Project is."

"Otherwise, we can include the Leviathan Zai Zai in the plan in advance, but in this way, a large amount of biological energy is needed to upgrade the Mother Nest."

Lin Mo originally wanted to wait until the zombies in the main world evolved again before carrying out a large-scale cleanup. Now it seems that it can be put on the agenda directly, but, for the laying of the Creep, those zombies can be caught by the Creep Zai Zai, and then slaughtered after they evolve, anyway, the zombies don’t need to eat or drink.

Thinking of this, Lin Mo's eyes gleamed straight, a business with sure profits! A big win!

"Kaka, let's go home. Let the Overmind Zai Zai here fight a little more conservatively, but don't stop the pace of the attack." Lin Mo waved her small hand and said seriously.

"Okay." Kaka drooped her small tentacles, reluctant to have her slacking time interrupted.

Lin Mo said a word, but Kaka's work started immediately. For example, if the Queen goes to the main world, how many Zai Zai should she take with her? And how many Zai Zai should be sent to the military parade in the main world?

Currently, there is no race in the other world that can face the Zai Zai head-on. In the case of the other world, the Overseer Zai Zai is greatly restricted, after all, many mutated creatures live underground.

And the location currently observed by the Overseer Zai Zai is almost at the height of a low-altitude satellite, and a lot of pheromones cannot reach this location at all.

The Creep Zai Zai has also become a strange landscape, like a large area of ​​completely inexplicable geographical problems, enough for "Approaching Science" to broadcast for at least half a year.

In the end, Kaka still felt that she should take more Zai Zai back, not to increase the workload of the Overmind Zai Zai in the other world, but simply to protect the Queen's safety.

Yes, that's right.

"Guji!"

(This is tyranny! You are not democratic!)

((٩(//̀Д/́/)۶))

"The Queen's safety needs to be guaranteed!"

(￣w￣)

"……"

(눈_눈)

"……"

o((＞w＜))o

Lin Mo naturally didn't know that Kaka was doing this. Lin Mo was bored sitting on the back of the Overlord Zai Zai, quietly watching the Zai Zai who were constantly working below. Although the environment was not very good and the scenery was average.

But Lin Mo still smiled, and the breeze blew Lin Mo's white hair, dancing with the wind.

"Zai Zai, soon this will all be our world."

"Queen, we are ready, we can go back at any time."

Kaka didn't know when she had come to Lin Mo's back, quietly suspended there, until Lin Mo broke away from her thoughts, then she spoke.

Lin Mo nodded, and the Overlord Zai Zai under her feet roared unwillingly twice.

"Queen... pat pat..." ๐·°(৹˃̵﹏˂̵৹)°·๐

Lin Mo was stunned, then smiled dotingly, "Okay, pat pat head."

"Kaka, let the Overmind Zai Zai go all out directly, we won't bring the Zai Zai, when we take down all of this place, we will all go home."

Lin Mo was also a little tired of this kind of schedule that needed to be reversed.
