After setting up the instruments, several people quickly returned to the tank.

The mecha set up some surveillance cameras nearby, and then moved a little further away.

The tank didn't drive very far, it was just some distance away from the instrument. After doing all this, there was a response from the other side.

"Report to base, everything is ready."

"good."

Wei Zheng picked up the walkie-talkie.

"start!"

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

They made some changes to this instrument and controlled it remotely for safety reasons.

After all, no one knows whether 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 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 in the air.

Their eyes were fixed on the small instrument.

There was a bright light flashing on the instrument and it also made a sound, which ushered in the zombies around it.

Neither the mecha nor the people in the tank stopped him.

They all stared closely at the small instrument.

If something goes wrong with this 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 vibration sound.

The sound waves generated by the vibration spread instantly.

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

But in full view of everyone, a burst of light emitted from the machine.

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

"Didi, testing is in progress...The test has no results."

"...the test showed no results."

This special substance does not exist on earth at all.

Soon, they discovered that the zombies that were the first to approach the instrument turned into a pile of rubble.

Immediately afterwards, all the zombies illuminated by the beam within a radius of ten meters were reduced to ashes, and this area continued to expand.

This is just the beginning.

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

Since the zombie virus invaded, the water flow was polluted, and a heavy rain fell, everything suddenly contained highly toxic substances and turned into a strange dark black color, making it impossible to plant at all.

But now, the soil within a radius of two kilometers has changed.

All were purified by the surface purifier, and suddenly and gradually returned to their previous color from dark black.

The light is still shining.

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

The soldiers in the mechas and tanks opened the hatches as if they were fascinated by the vibrant scene outside.

Wei Zheng frowned when he saw this and warned sternly, "You all should be careful."

"Yes, sir."

Although they agreed, they still couldn't help but open the hatch and go out.

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

Warm and warm, as if I were back in my mother's arms.

They couldn't help but raise the corners of their mouths, open their arms, and let the beam of light shine on every inch of their skin.

"Testing completed, sir, this light does not cause any harm to the human body, and..."

The soldier's voice hesitated for a while, and then he said: "This light is very much like sunlight. This feeling is...the sunlight before the end of the world. It is very comfortable when it shines on your body."

While they were talking, they had already stepped off the mechas and tanks.

Their feet stepped on the soft soil, and their whole bodies felt as if they were stepping on cotton.

An older warrior with white hair on his temples knelt down, trembling hands, and gently rubbed the earth with his rough palms.

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

"This, this... is this the aroma of earth? This is the earth before the end of the world, with the fragrance of grass. It has no industrial pollution. It is pure natural earth. I have smelled this kind of earth when I was a child."

He gently picked up the soil with his hands and looked at it obsessively.

Several soldiers nearby opened their arms and felt the warm light.

"Is it my imagination? I feel like the air here is much purer."

"I feel the same way. This is what is called purification. Zombies are dirty. The substances that pollute the land are dirty. They have all been purified. Look!"

Suddenly, a soldier's exclamation came.

But I saw him staggering to a corner and shouting excitedly, "Is this grass?"

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

These tenacious lives hidden in the soil have been waiting for this opportunity.

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

With the landmark purifier as the center, all zombies within a radius of thousands of miles have been reduced to nothing, the land has been renovated, and professional agricultural researchers have come to explore the land conditions.

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

Smelling the familiar scent of grass and earth here, these old professors were so excited that they were speechless.

"I smell a familiar smell. This is all soil that has not been contaminated by industry. This is absolutely fertile soil!"

"This soil should be suitable for planting. Come on, Xiao Wei, bring me my tools and let me take a look."

The student quickly took out the tools from his backpack with a smile on his face.

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

Wei Zheng took Luo Xu to the surface purifier.

Wei Zheng smiled and said: "This surface purifier is a good thing that you got after you killed a strange beast."

Luo Xu nodded, but didn't feel anything.

Stepping on this purified land, she breathed in the fresh air and felt much more comfortable all over.

"You are our biggest hero. Tomorrow the Central Committee will hold the 39th meeting, and we will discuss your rewards. Do you have anything you want? In this case, as long as the country has it, whatever you want,

Basically everything can be satisfied.”

Luo Xu swallowed hard.

You can do whatever you want...

This kind of treatment was unimaginable in my previous life.

She was originally an ordinary person. When she came to this world and suddenly encountered the end of the world, she would inevitably panic.

but……

When Wei Zheng asked her what she wanted, she hesitated.
Chapter completed!
