Before the end of the world, these old professors were all well-known bigwigs in the industry, not to mention some of them had evolved brain powers and became smarter.

Under Lin Xiaotang's order, they quickly studied the principle of the sonic transmitter and successfully assembled dozens of similar instruments.

During this period, new cars will come from time to time, and new instruments will continue to be launched every three to five.

Lin Xiaotang was not polite and accepted them all.

She put them all in her base, and let them summon zombies for herself.

At the same time, she also learned a new research result related to zombie virus from the mouths of Hua Mingxiu's master and apprentice——

Zombie viruses are probably not the results of human research.

"We did genetic analysis on it and found that there are no obvious traces of human influence in its genome structure," Hua Mingxiu said. "Compared to those aberrant viruses that were artificially created or influenced by radiation, its formation The rules are more natural.”

"So, you mean, it wasn't made by anyone?"

Lin Xiaotang asked with great interest.

"Yes," Hua Mingxiu nodded affirmatively and said, "My teachers and I are well aware of the level of development of modern biology. It is far from enough to research such a virus based on the current level of technology."

In other words, according to the modern level of technology, there is no way to provide researchers with an environmental condition that can create zombie viruses.

If someone really wants to create it, their most likely ending is to be infected by various similar aberration viruses before the zombie virus is formed, and die miserably in the laboratory.

"interesting……"

After hearing Hua Mingxiu's words, Lin Xiaotang's eyes flashed with interest.

You must know that in the original plot, both the male and female protagonists, and others in the outside world, firmly believed that the zombie virus was created by a group of anti-social researchers.

They spread it out and caused the birth of the end times.

Who would have thought that this virus appeared on its own.

And the first group of scientists may have just discovered it and wanted to study it.

"Excuse me, Miss Lin, should our research continue?"

Seeing that Lin Xiaotang did not speak, Hua Mingxiu asked cautiously.

"Go ahead," Lin Xiaotang said without hesitation, "If you can't study viruses, it's the same as studying zombies."

Originally, Lin Xiaotang wanted them to develop a zombie virus vaccine as in the original plot.

But now, she gave up the idea.

Because of the zombie vaccine in the original plot, its biggest role is not to let the infected ordinary people survive, but to kill the zombies.

Rather than a vaccine, it's a biological weapon against zombies.

Now that he has learned about the zombie virus, Lin Xiaotang wants to figure out what kind of existence they are, rather than destroying the zombies.

Wouldn't that make it more interesting?

However, before that, what she has to do is to make good use of the coming zombie tide.

Thinking of this, Lin Xiaotang raised his head and glanced thoughtfully in the direction of Kyoto.

...

"Yunyan, how is your situation?"

A few days later, at the Ark base, a handsome man in a military uniform hurried over.

His expression was serious and cold, but he looked at the woman in front of him with a rare tenderness in his eyes: "If you have anything, you can tell me."

After listening to Duan Junran's words, Qi Yunyan shook her head.

She showed a faint smile and said, "It's okay, Brother Duan, I don't have any shortage of people here."

City B is not far from their base, and with that batch of instruments dropped in City B, at least 80% of the zombies who want to attack their base will be led away.

They only need to do the most basic defense, that's enough.

As the leader of the Ark Base, why doesn't Duan Junran understand this?

Looking at Qi Yunyan, who is strong, decisive, resourceful, and completely different from other weak women, Duan Junran's eyes moved slightly, and his tone involuntarily softened a lot: "I have worked hard for you recently."

Feeling Duan Junran's inadvertent warmth, Qi Yunyan's heart was also warm.

"It's okay, as long as it can help everyone and the base, that's enough," she said.

Qi Yunyan knew that these days, many people thought she was stupid.

Obviously she has the most supplies, and she has paid the most for the base. Even Duan Junran was rescued by her at the beginning, but she chose to give Duan Junran the position of the leader of the base.

But no one knows what kind of height this man with the thunder-type ability will eventually reach.

She believes that her choice will not be wrong, and she also believes that she and Duan Junran will definitely have a satisfactory result.

After the two said a few more words, they went to the city wall of the base together.

It was less than two hours before the zombie tide broke out. As leaders, they need to lead by example and take the initiative to stand up to protect the base, so as to win people's hearts.

Apart from Qi Yunyan and Duan Junran, other abilities in the base also climbed the city wall.

All took up arms and waited with bated breath, ready for the battle to come.

Just don't know why, they looked at it and found that the base was empty, and there were almost no shadows of a few zombies.

You must know that even in normal times, there will be a few zombies constantly wandering outside the base.

Is this the harbinger of the zombie tide coming?

Faced with this scene, some people speculate in their hearts, and some people realize that something is wrong.

Among them, Qi Yunyan was the most shocked.
