The guards had retreated to the last line of defense.

They were armed in their hands, and looked at the slightly twisted door that had been slammed into again and again.

Seeing that the zombies outside were about to rush in, suddenly at this time, the movement outside actually calmed down.

The guards had looked at each other, and there was silence outside, and pins could be heard.

"Outside...... What's going on? ”

The captain frowned and reprimanded in a low voice: "Be quiet, it is very likely that it is the conspiracy of the zombie emperor, hehe, this group of kings and eight calves is actually playing strategy, this brain is really good." ”

"Cheer me up!"

Everyone cheered up, armed with guns, aimed at the door, nervous muscles all over their bodies, waiting for the movement outside.

After waiting for about ten minutes, their muscles were sore, but they still didn't hear any sound.

Just when everyone was puzzled, suddenly from outside, a dazzling light came.

The light came through the crack in the door, and the mere glimmer of light was enough to brighten up the entire dark underground room.

Seems......

Outside, there's a sun slowly rising.

It's a weird scene.

This is the underneath research institute.

This place is at least a thousand meters above the ground, how can there be a sun!

"What's going on out there?"

"What's the matter with this light?"

"Shall we go out and have a look?"

One of the guards approached the door, listened with his ear to it, and shook his head.

"It's weird that there's no movement outside."

Dozens of people turned their eyes in the direction where the captain was.

"Captain, is the backup team here?"

"Impossible, if the support team arrives, why is there no gunfire outside?"

"It's too quiet, I'd rather hear the screams of the zombies, at least knowing that it's normal zombies outside."

"Although I feel that this may be a machime of mutant zombies, but ...... This beam of light is also too weird! ”

The light beam outside was still continuing, and the whole room was very bright, and someone stepped forward to reach out to let the beam shine on their hands, and there was a hint of warmth, which was clearly the feeling of the sun's light.

The captain frowned and reprimanded, "This thing is most likely some kind of chemical weapon, come back quickly, be careful." ”

The guard grinned, "It's so warm, Captain, I feel like it's sunshine, I know how the sun feels on my face, it's so warm." ”

A few people were curious and came forward to try it.

The beam didn't hurt their bodies in the slightest, but was very warm.

Ever since the end came, the weather had been foggy throughout.

Plants are dying, rivers are drying up, and the air they breathe is getting thinner and thinner, and it is extremely polluted.

Although the country has long used technology to make air purifiers, they will still miss the taste of nature.

Even if the sun shines down, it needs to penetrate the layers of clouds and fog, and you can't feel any temperature.

But this beam of light made them feel the sunshine they hadn't seen for a long time.

It was still quiet outside, and there was no movement.

"The zombies outside must have left, right? How do you know that there is still no movement? ”

"Leave? The zombies have rushed in, how can they leave by themselves? Your idea is outrageous. ”

The team leader paced in place with some restlessness, and finally made a bold decision.

"Let's go out and have a look, we can't be locked up here for the rest of our lives."

"Yes!"

They took precautions, and the two of them removed all the clutter at the door.

When the things blocking the door were cleared little by little, the others were nervous and pointed their weapons at the door.

Kicking the door open, they nervously raising their guns.

However, the scene in front of him stunned everyone.

The zombies blocking the outside are all gone, leaving only a thick layer of ash on the ground.

All the zombies, all gone.

"What's going on?"

They were dumbfounded, they couldn't believe their eyes.

If it weren't for the uneven and deformed door, which showed the traces of the zombie's existence, they might even wonder if what they had just experienced was a dream.

"Zombie ......" someone crouched down and washed and examined the layer of ashes on the ground.

"All burned to ashes? What did it do? That light? ”

The moment they pushed the door open, the light outside gradually dimmed, and now it was completely invisible.

Looking around, they suddenly saw a bright light around the corner of the corridor.

The captain waved his hand, "Let's go, go over and have a look." ”

They were still vigilant, but there was no trace of zombies around.

Just following the light, they finally heard the roar of the zombies, and they quickly hurried to another laboratory.

Sure enough, here they saw a bright light that was like the sun, dazzling but not dazzling.

It was as if the sun was shining on those zombies.

In an instant, a raging flame ignited on the zombie's body, and in an instant, the zombie was directly turned into ashes.

The crowd was stunned.

The whole room, there were thirty or forty zombies, and they were reduced to ashes.

This picture is spectacular!

The light also shone on them.

It's still so soft, as if the skin has been gently caressed by a big gentle hand.

A young guard suddenly thought of something, hurriedly took out his mobile phone, and adjusted the screen to the live broadcast.

He saw that the entire live broadcast room was being swiped by the barrage.

They're all brushing things that were embodied in the last Atlas.

"Congratulations on obtaining Building Shield*10, Base Defense +10%, Base Cleaning System*10 (for 1 hour)"

The entire screen was swiped with this sentence, with only a few other comments occasionally.

"I don't know which lucky one will get these."

"Do you know what a base cleaning system is? Do you help with cleaning? ”

"This embodiment shouldn't be as superficial as you think."

The guard handed the phone to the captain.

The captain looked around, looking at the fading light, and sighed.

"It's true, it's not as superficial as they think, it turns out that this is the so-called cleaning system."

It's just that it's the zombies that are cleansed.

Determined that the light would do no harm to humans, the guards were a little excited, and divided into small teams to search for the fading beam.

The light is so comfortable on your body that it's like basking in the sun.

Ten minutes later, the captain found the base's surveillance camera and sent it to the central command post.

At this time, the central command post had already received surveillance camera video from three different research institutes.

At the same time, three research institutes across the country were attacked.

These zombies are now actually starting to attack the scientific research institute of humans.
