I have a space station

Soon, a deep pit was dug. He took out the transmitter, placed it in the pit, and then backfilled it.

With all the work done, the soldier didn't leave, standing quietly in the ring of fire, waiting. He had protective clothing on, so even if the rats attacked, he wouldn't be afraid.

One minute, two minutes, ...

Soon, an hour passed, and the zombie rats outside showed no reaction.

"What's going on? Is it not working?" The soldier looked at the gradually weakening fire and muttered to himself.

If it didn't work, it would be troublesome. He didn't know how many people would be bitten, and this settlement would probably be ruined.

Two hours later, the flames of the fire ring died out, and the zombie rats extended into the ashes as if they didn't care about their lives. Although the fire was out, the temperature of the ashes was still very high. As the rats continued to attack, the ashes were stirred up into the sky, and the air was filled with a strange, rotten, burnt smell.

People moved closer to the center, gathering together.

Seeing that the rats were about to attack, everyone closed their eyes in despair.

But after waiting for a long time, they didn't feel any pain. Everyone opened their eyes and saw that, centered on them, the rats were slowly disappearing one by one.

The light was too dim, and they couldn't see how these rats were disappearing.

...

The night passed, and dawn arrived.

The rats on the streets had disappeared.

The soldier contacted the plane via satellite phone to pick him up, and then left in a hurry.

The entire street was a mess, filled with smoke.

Several teams of security members shuttled through the streets and alleys, checking the survivors one by one. If anyone was bitten, they would all be taken to another newly arranged isolation settlement.

Those who went there would only face death.

Overnight, the number of deaths in the Jiangning settlement exceeded 1/3, and 2/3 of the survivors were bitten. It was a tragic scene.

But there was no way around it. This was the apocalypse, this was reality. The dead were gone, and the living had to continue living.

Even if someone resisted, it would ultimately be futile in the face of the general trend. The surviving people would not agree to an infected person living with them, as their safety would not be guaranteed.

As for sympathy? Sorry, I sympathize with you, but please leave!

...

The departing soldier quickly returned to headquarters.

"How was it?" Zongzhen Yue asked anxiously when he saw the returning soldier.

"Reporting Commander, it's indeed useful, but..." The soldier didn't know how to describe it.

"But what?" Zongzhen Yue frowned.

"But it's not quite the same as imagined," the soldier said, searching for the right words.

"Where is it different?" Zongzhen Yue continued to ask.

"How should I put it, the effect is a bit slow," the soldier replied.

"How slow?" Zongzhen Yue asked step by step, knowing that the soldiers generally didn't have a high level of education, so he let him slowly organize his words.

"Logically speaking, after the transmitter is buried in the ground, it should take effect immediately, and the zombie rats should quickly escape. But in reality, it took almost two hours for the rats to change," the soldier replied.

"Oh? Is that so?" Zongzhen Yue imagined the scene, thought for a long time, and felt that a slower effect was acceptable. Maybe there was some activation process, and it would be better after activation.

"Anything else?" Zongzhen Yue asked.

"There's also..." The soldier hesitated.

"What is it?" Zongzhen Yue frowned.

"It's just that the rats didn't run away, but... but disappeared!" The soldier said through gritted teeth.

He didn't even believe what he said, but the light was too dim at the time, and he might have missed some details.

"Disappeared?" Zongzhen Yue was puzzled.

"How did they disappear?" he continued to ask.

"They just disappeared into thin air. Commander, the light was a bit dim at the time. I did see them disappear, but as for whether there were other reasons, I don't know," the soldier said aggrievedly.

Zongzhen Yue frowned, unable to figure it out.

So he let the soldier go down to rest, and he called Yan Fangfang again.

After listening to Zongzhen Yue's description, Yan Fangfang knew what was going on. Most likely, the nanobots in the transmitter needed a production process, and then the produced nanobots decomposed the rats, just like her tag. It's just that the decomposition process was too fast, and he thought they had disappeared.

But since it was called an ultrasonic transmitter, she had to make things up.

"Uncle Zong, maybe it was too late and the soldier saw it wrong? The rats should have burrowed into the ground, right? How could they disappear into thin air? That's not scientific! Besides, do you care whether they disappear or run away? Isn't it good as long as it works?" Yan Fangfang comforted him with a fabricated story.

"That's true!" Zongzhen Yue no longer struggled with it.

As long as it could drive away those annoying zombie rats, that was enough. As for the principle of driving them away? He wasn't a scientist, why waste his brain on that?

Having confirmed that the ultrasonic transmitter was indeed useful, Zongzhen Yue was relieved. However, he wasted one for the experiment, so he replenished his stock from Yan Fangfang again.

March 28, 2055 AD.

Afternoon.

Kyoto, Parliament Building.

"Councilor Yan, please inform everyone about the zombie rats," the Speaker said.
