After setting up the instruments, several people hurried back to the tank.

The mecha placed some surveillance cameras nearby, and then it was a little farther away.

The tank didn't drive very far, just a distance from the instrument, and when it was all done, it responded.

"Report base, everything is ready."

"Okay."

Wei Zheng picked up the walkie-talkie.

"Let's go!"

As Wei Zheng's order fell, the professional engineers on those tanks began to operate.

They made some changes to the device, and to be on the safe side, they controlled it remotely.

After all, no one knows if such a cleaning system will treat humans as 'garbage'.

Everyone in front of the screen held their breath.

Everyone knows what it means if this surface purifier can purify the zombies on the ground.

"The countdown to the start of the surface purifier begins, ten, nine, eight, seven......"

As the countdown began, everyone's hearts were lifted into the air.

Their eyes were fixed on the small instrument.

There was a bright light flickering on the instrument, and there was a sound, which ushered in the zombies around it.

Neither the mech nor the people in the tank stood in the way.

They were all staring at the little instrument, too.

If something goes wrong with the instrument, they will be the first to die.

“…… Four, three, two, one......"

The countdown ended, and the Engineer pressed the button.

As the button was pressed, the entire machine made a buzzing sound.

The sound waves generated by the vibration spread out in an instant.

The strange thing is that such sound waves have no effect on anything, and the picture is still so clear and smooth.

But in front of everyone's eyes, a burst of light emanated from the machine.

This bright light is as dazzling as the sun, but it is not dazzling, and the mecha's system can clearly detect it, and find that this light book contains some special substance.

"Didi, it's being tested...... The test was inconclusive. ”

“…… The test was inconclusive. ”

This particular substance does not exist on the earth at all.

Soon, they discovered that the zombies who had approached the instrument first had turned into a pile of ruins.

Immediately after, within a radius of ten meters, all the zombies that were irradiated by the beam were all turned into ashes, and this range was still expanding.

And that's just the beginning.

After the zombies disappeared, the soil in that area began to be purified.

Since the zombie virus invaded, the water stream was polluted, and a rainstorm fell, all of a sudden it contained highly toxic and turned into a strange dark black, which could not be planted at all.

Now, the soil in a two-kilometer radius has changed.

Purified by the surface purifier, it suddenly gradually returns from dark black to its previous color.

The light is still shining.

The ruins of the building disappeared, the ashes of the zombies disappeared, the ground gradually became flat, and all the construction debris and uneven ground were all restored to the best condition.

The fighters in the mechs and tanks, seeing such a vibrant scene outside, seemed to be fascinated and opened the hatch.

Seeing this, Wei Zheng frowned, and reminded sharply, "You all be careful." ”

"Yes, sir."

Despite this, they couldn't help but open the hatch and go out.

As the hatch slowly rose, they felt the light on their faces.

Warm, warm, as if returning to the mother's embrace.

They couldn't help but curl the corners of their mouths and spread their arms to let the beam hit every inch of their skin.

"Done, sir, this light doesn't do any harm to the human body, and it's ......"

The soldier's voice hesitated for a while, and then it arrived: "This light is very much like the sun's rays, this feeling is ...... The sun's rays before the end of the day are very comfortable to shine on the body. ”

As they spoke, they had already stepped off the mechs and tanks.

Their feet were on the soft earth, and their whole body fluttered, as if they were stepping on cotton.

An older, gray-haired warrior crouched down, trembling his hands, and gently rubbing the ground with his rough palms.

He knelt on the ground, his whole body prostrate on the dirt, and took a deep breath reverently.

"This, this...... Is it the aroma of the earth? This is the pre-apocalyptic soil, with the scent of grass, without any industrial pollution, pure natural soil, I smelled such soil when I was a child. ”

He gently picked up the dirt with both hands and looked at it obsessively.

A few warriors next to him spread their arms, feeling the warm light.

"Whether it's my delusion or not, I feel like the air here is a lot purer."

"I also feel this way, this is the so-called purification, zombies are dirty, the substances that pollute the land are dirty, all are purified, look!"

Suddenly, a warrior's exclamation was heard.

saw him staggering to a corner, and shouted excitedly, "This, is this grass?" ”

A few people looked over there, and sure enough, some grass grew on the ground.

These tenacious beings, hidden in the dirt, have been waiting for this opportunity.

Half an hour later, Luo Su and Wei Zheng arrived in the same helicopter to the purified area.

With the landmark purifier as the center, all the zombies within a radius of thousands of miles have been reduced to nothing, the land has been repaired, and there are already professional agricultural researchers to explore the land situation.

With the support of the students, these old professors got off the plane tremblingly.

Smelling the familiar smell of grass and earth, these old professors were speechless with excitement.

"I smell the familiar, it's all unpolluted soil, it's absolutely fertile soil!"

"This soil should be plantable, hurry up, Xiao Wei, bring my tools, I'll take a look."

The student smiled and quickly took out the tools in his backpack.

They are all carefully collecting specimens and preparing to take them back for study.

Wei Zheng took Luo Su to the surface purifier.

Wei Zheng said with a smile: "This surface purifier is a good object that you have manifested when you killed a strange beast. ”

Luoxu nodded, but she didn't feel anything.

Stepping on this purified land, she breathed in the fresh air, and only felt much more comfortable up and down.

"You are our greatest hero, tomorrow the Central Committee will hold the 39th meeting, when the time comes, to discuss the reward for you, do you have anything you want? In this case, whatever you want, as long as the country has it, you can basically meet it. ”

Luo Su swallowed hard.

Whatever you want, you can ......

This kind of treatment was unimaginable in the previous life.

She was originally an ordinary person, and when she came to this world, she suddenly encountered the end of the world, and it was inevitable that she would panic.

But......

When Wei Zheng asked her what she wanted, she hesitated.

She really couldn't think of it for a while.
