Apocalypse: No rebirth! Time to upgrade the sewers!

[Command received, construction in progress... estimated time 10 seconds...]

【10...9...8...】

As soon as he finished speaking, the entire entrance area of ​​the shelter, including the ground and the walls on both sides, began to tremble violently.

buzzing...

The vibration stopped after a few seconds.

A screen appeared on the wooden wainscoting at the entrance of the shelter.

He walked up to the screen himself and asked the question in his mind.

"System, tell me about this shelter defense module."

[System notification: The shelter defense module consists of three parts.]

[1: A high-voltage electrical module is hidden in the ground in front of the shelter entrance. It can be activated via the control panel. It consumes electricity. It is already connected to the power generation room.]

[2: A combustion module is hidden inside the wall in front of the shelter door. It can be activated via the control panel. It consumes gasoline. Gasoline can be added next to the control panel.]

[3: A laser module is hidden on the door of the shelter, which can be activated via the control panel. It consumes electricity. It is already connected to the power generation room.]

Song Qing paused for a moment.

He could understand high-voltage electricity and combustion modules.

But laser?

Is it the laser he imagined?

Song Qing's expression turned serious.

He spoke to the three women behind him.

"You all step back a little."

Although the three women didn't understand what had happened, they obediently backed away when they saw Song Qing's serious expression.

Song Qing raised his hand and began operating the control panel.

The screen displays three clear virtual switches, corresponding to electric shock combustion and laser, respectively.

He clicked on the last one directly.

Laser Module

hum...

A low, resonant energy hum sounded.

Suddenly, a net woven from red light appeared on the steel door.

A red light net covered the entire door.

Song Qing extended her right hand.

A thought crossed my mind.

Extremely cold!

Deep blue ice crystals instantly spread from his arm, and in the blink of an eye, his entire arm was made of ice crystals.

Then, he brought his icy fingers to the laser net.

Nourishes...

There was no loud noise.

The instant the ice finger touched the red light, a small plume of white steam rose up.

It only took a few seconds.

Song Qing's icy fingers had been completely severed.

Song Qing withdrew her arm.

The severed finger re-coagulated.

The ice he just condensed wasn't particularly strong.

Even so, the power to cut it off in a few seconds is already quite impressive.

"husband"

Gu Ya walked over and took his arm. He asked curiously.

"Was that a laser treatment?"

Song Qing nodded.

"Yes, it's laser. I just upgraded the shelter's defense modules."

Bai Ruolin, on the other side, also came over, her little face full of excitement.

"Laser! This is the first time I've ever seen one in real life. I've only ever seen them in movies before! It's so cool!"

Song Qing patted the little girl's head and looked back at the control panel.

He found the start switch for the combustion module and pressed it directly.

However, nothing happened.

There was no change on the screen, and the expected flames did not appear.

Song Qing thought for a moment and then understood.

He hasn't fueled the module yet.

With a thought, a blue gasoline can appeared on the ground.

On the wall, there is a groove with a metal flexible tube connected to it.

Song Qing inserted the hose into the gasoline can and pressed a button on the control panel.

buzzing...

A soft sucking sound was heard.

He added about fifty liters of gasoline.

He took the gasoline can back.

After doing all this, Song Qing turned on the combustion module switch once again.

This time, there was a response.

On the screen outside the monitoring shelter, the image was instantly covered by a sea of ​​orange-red flames.

Blazing flames erupted from the walls on either side of the door.

"Wow"

Gu Ya and Bai Ruolin couldn't help but gasp in surprise.

Wang Jie was also stunned.

Song Qing turned off the combustion module with satisfaction.

He then turned on the switch for the last high-voltage electrical module.

The image on the screen changed again.

next second.

It's sizzling!

Blinding blue arcs of electricity leaped wildly across the ground outside the shelter.

The entire passageway was illuminated by this blue electric light.

Song Qing watched this scene through the surveillance camera.

If someone were standing on it at that moment, they probably wouldn't last even a second before being electrocuted into a charred corpse.

He shut down the high-voltage electrical module.

These defensive measures are not bad.

At least, when I'm not home, Wang Jie and the others have a basic guarantee of safety.

He turned around and said.

"If any mutated creatures or strange people come over when I'm not home, just turn on this function without hesitation."

Wang Jie nodded emphatically.

"Okay, honey."

However, he couldn't help but sigh inwardly.

Sigh, all 305 points I worked so hard to earn have been gone in an instant.

It's like sprinkling water.

Song Qing felt it was necessary to grind for more points.

By the way, it's time to boost my constitution points.

He thought about it carefully.

Because of the helicopter that lured them there, almost all the zombies in the West District were attracted to the East District.

That's why Xicheng District is so safe.

The situation in the northern district is unclear, and it's still Wang's territory. It's quite a distance from his home.

But Dongcheng District...

The zombie density there is definitely higher than you can imagine.

There is definitely a little bit of danger.

However, the profits are enormous.

Lots of points and lots of physique points.

Previously, his strength was insufficient, but now things are different. His attack, defense, and speed are all incomparable to what they used to be. Even if he really can't beat him, he can simply teleport away.

Thinking of this, Song Qing's heart began to burn with excitement.

He has made his decision.

He needs to take the initiative.

He turned away and stopped looking at the control panel.

Song Qing glanced at the time on her phone.

7:20.

Song Qing said, "I'm going out for a bit."

Gu Ya walked over and took his arm.

"Honey, take me with you."

Song Qing shook his head.

"This time won't do; I'm going to act alone."

The zombies in Dongcheng District must be very dense, and with Gu Ya by his side, he will be a bit overwhelmed.

Gu Ya wanted to say something more, but in the end, she hesitated and nodded.

"Then you must be careful."

Wang Jie also came over.

"husband...."

A black walkie-talkie appeared out of thin air in Song Qing's hand and was handed to Wang Jie.

"Honey, let's use this contact method. Call me anytime if anything happens."

Wang Jie took it.

Song Qing continued speaking while adjusting his collar.

"Just wait for me at home, I'll probably be back tonight."

"With a defense system in place, don't be afraid even if something comes at you."

After he finished speaking, he took one last look at the three women in his home.

next second.

Song Qing's figure flashed and disappeared into thin air from the shelter.
