The guards have retreated to the last defensive gate.

They held weapons and looked at the slightly twisted door that was knocked 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 in shock. It was so quiet outside that you could hear a pin drop.

"Outside...what's going on?"

The captain frowned and rebuked in a low voice: "Everyone, be quiet. It's most likely the zombie king's plot. Haha, these bastards are actually playing tricks. They have really good brains."

"Everyone cheer me up!"

Everyone cheered up, holding guns and pointing at the door. Their muscles tensed nervously, waiting for any movement outside.

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

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

This bright light shines through the crack in the door, and just a wisp of light is enough to brighten up the entire dark underground room.

as if……

There is a sun rising slowly outside.

This scene is so weird.

This is the research institute down there.

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

"What's going on outside?"

"What's this light about?"

"Should we go out and take a look?"

A guard came to the door, put his ear against the door, listened carefully, and then shook his head.

"There's no movement at all outside. It's really strange."

Dozens of people turned their attention to the direction of the captain.

"Captain, has the backup team arrived?"

"Impossible. If the backup team arrives, why are there no gunshots outside?"

"It's too quiet. I'd rather hear the roars of the zombies. At least I can know that the ones outside are ordinary zombies."

"Although I feel that this may be a conspiracy of mutant zombies, but... this beam is too weird!"

The light beam outside continued, and the whole room was very bright. Someone stepped forward and stretched out his hand to let the light beam shine on his hand. There was also a hint of warmth, which was clearly the feeling of sunlight.

The captain frowned and scolded, "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 this is the sun. I know the feeling of the sun shining on your face, it's so warm."

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

This beam of light did no harm to their bodies, but was very warm.

Since the end of the world, the weather has been foggy from beginning to end.

Plants died, rivers dried up, and the air they breathed became increasingly thinner and became extremely polluted.

Although the country has already used technology to produce air purifiers, they still miss the smell of nature.

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

But this beam of light made them feel the sunshine that they had not seen for a long time.

It was still quiet outside, without any movement.

"Could the zombies outside have left? How do you know there's still no movement at all?"

"Leave? The zombies have rushed in, how could you leave on your own? Your idea is outrageous."

The team leader paced in place a little restlessly, and finally made a bold decision.

"Let's go out and take a look. We can't be locked up here forever."

"yes!"

They took defensive measures, and the two of them moved all the debris from the door.

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

Kicking the door open, they raised their guns nervously.

However, the scene in front of them shocked everyone.

All the zombies blocking the outside disappeared, leaving only a thick layer of ashes on the ground.

All the zombies are gone.

"What's going on?"

They were stunned and couldn't believe their eyes.

If it weren't for the uneven and deformed door, which showed traces of the zombies' past existence, they might even have some doubts as to whether what they just experienced was a dream.

"Zombie..." Someone squatted down and looked at the layer of ashes on the ground.

"Everything was burned to ashes? What did it do? That beam of light?"

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

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

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

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

Just following the light and rushing over, they finally heard the roar of the zombies. They quickly speeded up and arrived at another laboratory.

Sure enough, here they saw a light that was as bright as sunlight but not dazzling.

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

In an instant, the zombie's body was ignited with blazing flames, and in an instant, the zombie was directly reduced to ashes.

Everyone was shocked to see it.

The entire house, filled with thirty or forty zombies, was reduced to ashes.

This picture is so spectacular!

The light also shone on them.

It was still so soft, as if a gentle big hand was gently caressing the skin.

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

He saw that the entire live broadcast room was flooded with barrages.

What they swiped were all the things that appeared in the other world last time.

"Congratulations on obtaining the building protective cover*10, base defense +10%, and base cleaning system*10 (lasts for one hour)"

The whole screen was filled with this sentence, except for a few other comments occasionally.

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

"Do you know what the base cleaning system is? Are you helping with the cleaning?"

"This manifestation should not be as superficial as you think."

The guard handed the cell phone to the captain.

The captain looked around, watching the gradually disappearing light, and sighed.

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

It's just that the zombies are being cleaned.

After confirming that this light did no harm to humans, the guards were a little excited and divided into several small teams to look for the gradually disappearing light beam.

The light shining on my body is so comfortable, 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 received surveillance camera videos from three different research institutes.

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