At this moment, the No. 39 Sewage Treatment Plant was no longer as peaceful as before. The sound of gunfire and explosions resounded above the reservoir.

In this silent doomsday, residents in the distance can faintly hear the movement here.

As everyone continued to shoot, at this moment, the red light on their muzzles gradually dimmed until it completely disappeared.

This also means that weapons will no longer have the enchantment effect of silence.

But at this moment, muting the sound is no longer important. The most important goal of the Rat Exterminator team is to prevent these mutants from rushing over.

Fortunately, Ashley has now destroyed the slope, which has caused them all to be trapped in the reservoir below, and they will not be able to break through their defenses for a while.

"Damn it! Our ammunition is almost running out! We can't drag it out any longer! We must retreat quickly!"

Andrea's face became extremely ugly when she saw the mutants becoming more and more crowded.

The expressions of the other people were similar to his. They never thought that there were so many mutants hidden under the reservoir.

When I asked for information in the tavern before, I never heard there were so many.

The nearby residents also thought that there were only about 20 people here, which was already overwhelming, but the actual number of people was more than five times the expected number.

There are more than a hundred mutants, and they have no way to deal with them.

"You can't retreat directly! They will catch up!"

Morris pulled the trigger crazily and yelled:

"You guys leave first, I'll stay behind to break up the rear! This will hold them back!"

Several people were stunned when they heard this, and Andrea shook his head wildly.

"No! Boss! If you want to leave, you have to go first! I'll take the lead! You still have a sister-in-law to take care of after you go back! You can't die here!"

"Get out! I'm the captain, so of course I'm staying! Don't think I don't know, don't you have a daughter at home? Why are you pretending to be a loner here!? Get out of here!!"

Morris roared, and immediately blocked the other party's words.

He was already determined to die at this moment.

Anyway, I'm so seriously injured that I can't run fast.

In that case, it's better to give the chance of survival to those brothers who are fighting with him.

"I...I divorced my wife a long time ago...my ex-wife will take care of my daughter, no problem..."

Andrea made a quibble, but his confidence was obviously lacking.

Obviously he also knew that, judging from the current situation, it would be wisest to let the captain stay and break up the team.

But as a teammate who shares life and death together, how could he bear to leave the other party here alone to wait for death?

What's more, what they are facing is a group of mutants who eat people but don't spit out bones.

Just thinking about what will happen to the person left behind at that time makes people shudder.

While several people were still arguing over who should stay, the guy with glasses on the side slowly put down his gun, turned around and walked towards a small room on the side.

"Lumen! What are you doing!?"

Feeling the decrease in the firepower output around him, Kiko glanced in surprise at the direction where the glasses guy was going, with an expression on his face full of disbelief.

"He is right! You go quickly! Leave me alone! We are running out of ammunition! There is no time to waste! Get out of here!!"

Morris yelled.

"Farke! Farke! Farke! Farke! Farke!"

Kiko cursed several times in succession, but his feet did not move at all.

"Boom~Boom, boom~"

At this moment, a series of deafening sounds suddenly sounded around everyone, and even the ground shook slightly.

The movement was so loud and sudden that all the hunters in the exterminator team were stunned.

Not only them, but the mutants below who were continuously gathering here also paused and their offensive slowed down.

"what happened?"

Andrea raised his head in confusion, trying to find the source of the sound.

"Look! It's there!!"

Kiko pointed at the wall at the edge of the slope and shouted.

Everyone quickly followed his gesture and looked over.

At the top of the slope, there were two thick metal plates extending from the sides. Those sounds were exactly what the valve made when it moved.

"This is……"

Morris' expression changed, and then he seemed to have thought of something, and his face showed surprise.

"Quick, quick, quick! Shoot! Shoot! Don't let them come up! Use all the bullets!!"

The next moment, he suddenly shouted and called on everyone to continue shooting at the mutants.

The gunfire started again, and this time it seemed to be more violent than before.

Kiko was a little confused at first and couldn't figure out what was going on.

Why does the boss suddenly feel like he's been given a shot of chicken blood, with an excited expression on his face?

But later, as the two metal plates on the side continued to move, he finally understood what was going on.

It turns out that this is not a metal plate at all, but the valve of this reservoir!

As long as you wait for the two valves to be closed, you and others can lock those mutants down, and you will be safe!

Thinking of this, he couldn't help but look in the direction of the small house.

There, Lumen waved to him through the window and tapped his temple.

When Kiko saw this, he took a deep breath of air-conditioning.

Good guy, you are making fun of yourself for being brainless!

But now he is not angry at all.

There is no other way, who wants others to save themselves?

Below, as the reservoir valve closed, the mutants with even slower brains finally reacted and began to roar and rush upward.

Some mutants even started to pull on the two valves with their hands, trying to prevent them from closing.

However, such a huge machine cannot be stopped by humans, even if they are mutants.

The valve slowly closed with an unstoppable momentum, as if it were a Gate of Tartarus, which could immediately lock the devils below into hell.

At this final moment, everyone in the Rat Exterminator team was already red-eyed, and their firepower was fully activated. Even the twin blasting machine guns in Kiko's hands were almost useless.

"Ah ah ah ah ah!!"

There were gunshots and roars.

There was chaos at the scene, and sparks shone on everyone's faces, giving them a touch of madness.

"Didi~didi~didi~dip~"

There was a brief and rapid sound. It turned out that Lumen came back and dropped a concussion grenade towards the slope below.

"Cover your ears!"

The glasses guy reminded.

When Morris saw this, he threw away the gun in his hand without thinking, leaned over and covered his ears with both hands.

"Buzz!!"

The next second, powerful vibrations swept through, and the terrifying sound waves mixed with the air blew everything around them away.

The solid metal walls in all directions also vibrated, and dust fell from them.

Kiko lay on the ground and wanted to scold the culprit, but the sand and gravel flying around him made it hard for him to open his eyes, let alone speak.

If the aftermath is like this, let alone the mutants below who bear the brunt.

The few people who were blocked at the entrance of the slope and were about to rush up were immediately blasted away. Their bodies were torn apart in the powerful explosion, and they couldn't even scream.

The crowd behind them also had a hard time. They were swept downwards by the huge kinetic energy, and fell one after another like tarot cards.

"Boom!"

At the same time, the valve finally closed, and the two metal plates hit each other heavily, making a dull sound.

"Success!"

Morris fell to the ground.

The series of high-intensity shooting just now made his already serious injuries even deeper.

"Beep~ The purification process has been started~ The water level is being raised, please wait..."

Behind, an electronic beep suddenly sounded in the small house.
