In the end of the world, I become an immortal alone

“… … My entire army is annihilated … …”

Wang Lei's voice echoed in the command vehicle.

This spider-configured command vehicle was speeding towards the fortress, its massive tires kicking up layers of dust.

Through the window, large armored clusters could be seen following in the distance, each unit moving at full speed and undergoing simple reorganization while in transit.

Dongfang Zhenghong left sufficient firepower in the center of the desert to eliminate any wandering Blade Beasts.

As for the fortress, the most important thing now was to transport enough drones and their配套 control center back, and to find a way to seal the hole in the forty-ninth floor.

In the holographic projection, the cross-section of the fortress was magnified several times, and the red dots representing the Blade Beast swarm had already broken into the forty-ninth floor, rapidly advancing towards the forty-eighth floor.

Indeed, these Blade Beasts were not in a hurry to slaughter humans on the forty-ninth floor; they were frenzied, yet purposeful, with three not-yet-fully-grown General-level Blade Beasts commanding from underground.

“Blow up the connecting highway between forty-eight and forty-nine!”

“Yes!”

Dongfang Zhenghong said quickly, “Where are the defense forces?!”

“The vanguard has begun to enter the mid-city! Transporting heavy firepower will take a lot of time!”

“The connecting highway's self-destruct device is activated! Three, two, one, successfully destroyed!”

“The automatic weapons on the forty-ninth floor are activated! Firing at full force! The Blade Beast swarm is using a stacking method to move upwards!”

Dongfang Zhenghong stated firmly, “Tell them to hurry! Move faster! Close the fire escape doors on all floors except the forty-fifth floor! The fortress is entering lockdown mode on all floors! These Blade Beasts must be trying to break through our garrison troops!”

“Yes!”

“Increase the detection frequency! Has there been a response from the Espers?!”

“There has been a response! They will guard the mid-city and upper-city!”

Dongfang Zhenghong narrowed his eyes slightly, not saying much, but instead said, “Call! Tell them that Fortress 76 is grateful for their efforts! Issue the order to every squad! Tell the fortress garrison! The survival of the fortress's eight hundred thousand humans depends entirely on them! Have each brigade commander guard their assigned key locations!”

“Yes!”

Zhou Zhengde suddenly shouted, “Commander! A short-to-medium range missile has been launched towards the fortress, a blank missile!”

Dongfang Zhenghong frowned and looked at Zhou Zhengde.

Zhou Zhengde did not hesitate and directly displayed an image to Dongfang Zhenghong.

It was the view from the camera installed on the missile.

Wang Jixuan, wearing a helmet and a black combat suit, was holding the front of the missile tightly with thick, heat-resistant gloves on his hands.

The missile, which could calculate its trajectory and flight control on its own, was targeting the wasteland in the southwest corner of the fortress.

What was the point of him going back alone? Dongfang Zhenghong didn't quite understand.

Moreover, with a supersonic missile, even if he could withstand the acceleration, how would he stop it?

Although Dongfang Zhenghong wanted to ask, he didn't have time to pay attention to these things. He nodded to Zhou Zhengde and continued to dispatch the garrison troops, selecting defensive positions.

The first combat unit would arrive at the forty-fifth floor in six minutes;

Most of the fortress's heavy firepower could not be transferred to the inside of the fortress in a short time.

A bold and crazy idea took shape in Dongfang Zhenghong's mind.

The fortress was not a high-rise building; it was embedded in the earth, and each floor could support itself independently… He was the commander, and he had to protect the main body of the fortress, the people, the machines, and the industrial capacity.

Therefore, whether the remaining garrison could hold off this Blade Beast swarm was crucial.

“Commander!”

The female technician next to him suddenly stood up, her voice trembling as she tried to remain calm.

She reported quickly, “According to the fortress's surveillance footage, the Blade Beasts are exhibiting devouring mutations. Some Blade Beasts have evolved wing-like structures similar to mid-level Blade Beasts, and their outer shells have softened. This evolution is occurring on the forty-eighth and forty-ninth floors!”

Dongfang Zhenghong rushed to the female technician's console in two steps.

In the dozen or so stacked projection screens, Blade Beasts were devouring each other. Blade Beasts with wings were wobbling and taking off, then breaking away from the surging Blade Beast swarm and flying directly towards the forty-sixth floor.

Their numbers had already reached several hundred!

They… were going to the seventh floor to cut off the connection between the mid-city and upper-city, preventing the surface garrison and subsequent human reinforcements from entering the mid-city and lower-city, and then unleash a slaughterous revenge on the mid-city and lower-city!

The young queen of this Blade Beast swarm was dead; they were taking revenge!

Dongfang Zhenghong quickly ordered, “Close all fire doors on all floors of the mid-city immediately! Shut down the elevators! Activate all elevator shaft dividers! The passage on the seventh and sixth floors must not be lost! This is the main route for advancing downwards! Pile up people to defend it for me! What about the Espers! Have them go up too!”

“Yes!”

In the center of the sand table, red dots were rapidly rushing upwards.

They rushed into the forty-sixth floor, rushing towards the fire escapes in all directions. A small number encountered Espers, and most entered the fire escapes, rushing upwards rapidly.

Dongfang Zhenghong walked back to his seat, held the armrest and slowly sat down, taking a deep breath.

… …

Woo, woo!

The urgent warning sound echoed throughout the thirteenth floor of Fortress 76.

Wei Na patted the heads of the two young nurses in front of her and instructed, “You two hide in this bathroom and don't come out. I'll go see if they need any medical support.”

“Sister Na, don't go!”

“It's okay, I know how to use a gun.”

Wei Na quickly took off her high heels, put on the lightweight sterile shoes she used for surgery, and smiled gently:

“All the rooms in the mid-city have the same configuration. These alloy doors can withstand attacks from some low-level Blade Beasts.

“If you hear an order saying that the elevator shafts and fire doors are closed, that's when the real trouble starts. That means the Blade Beasts have already attacked. Each fire valve is fifty centimeters thick.

“Okay, you guys stay here for now. I'll go see if they need any help.”

“Hey, Sister Na!”

Wei Na waved her hand, closed the bathroom door, grabbed the medical first-aid kit next to her, took the pistol she had obtained through connections after the 'Hua Ge incident,' checked the bullets, loaded the gun, and quickly rushed out of the medical room with the first-aid kit on her back.

A team of security guards happened to be passing by outside.

“Can I help with anything?”

“Doctor Wei Na! Please go to the security shelter immediately! We are patrolling! Blade Beasts are breaking through upwards from the 49th floor! It is said that the lower-city cleanup team is gone.”

Wei Na asked, “Are there any elevators still working?”

“There should be, the central elevator should be!”

“Okay, thank you,” Wei Na turned and ran towards the central elevator.

In her understanding, the military would definitely need a large number of medical personnel later. She could report to the military camp, take the elevator from the thirteenth floor to the seventh floor, then transfer to the sixth floor, and then find the elevator that goes directly to the surface military camp.

However, Wei Na had only run two steps.

Woo, woo — —

After a long siren, an electronic synthesized female voice broadcasted throughout the fortress:

“Attention fortress residents, please return to your residences immediately, lock your doors, please do not panic, we are dealing with a small number of Blade Beasts.”

“Attention fortress residents, please return to… …”

“Please note that in order to prevent the Blade Beasts from roaming, the elevator shaft segmented dividers have been activated, and the elevators have been shut down.”

“Please note that the fire doors are being closed, please do not go outside the fire doors, all residents please return to your residences immediately and lock your doors.”

Has the situation become so bad?

Wei Na was about to return to the clinic to comfort the two young colleagues who had just arrived when a loud shout suddenly came from the capillary passage in the distance:

“Quick! Someone come! Who knows about machinery! Fire door number 6 is stuck!”

Wei Na was stunned, and immediately turned her head and ran in that direction.

Many figures were running towards fire door number 6.

The main body of the fortress had existed for decades, and there was a high probability of circuit aging. The fire doors were devices used to seal off each floor and had as many as four opening methods, which Wei Na had carefully read in the fortress manual.

Doctors in this era knew a little about medical equipment maintenance.

Wei Na quickly encountered seven or eight men and women. Everyone exchanged glances, said nothing, and ran towards fire door number six together.

A few minutes later, Wei Na arrived at the scene, panting.

There were already seven or eight security guards in the corridor leading to the fire door. Half of the heavy valve door was stuck and could not move, and a string of electric sparks was emerging from the wall in the corner next to it.

It really was a wiring problem.

“I'll do it! Intermediate mechanic!”

A middle-aged uncle shouted and rushed to the corner wall, skillfully pulling open the hidden valve on the wall, revealing a faint smoke inside.

There was a professional.

Everyone obviously breathed a sigh of relief.

Suddenly… …

The buzzing sound of flapping wings drilled into Wei Na's ears.

Wei Na was stunned. Everyone subconsciously looked at the fire door that had fallen halfway. Wei Na leaned slightly and looked into the dark fire escape.

The black vertical pupils that appeared on the white conjunctiva met Wei Na's eyes.

A slender Blade Beast, gathering its six sharp blade limbs, vibrated two pairs of crystalline wings, like a super-sized wasp.

Wei Na drew her gun and shot immediately!

This Blade Beast suddenly rushed forward from a stationary hover, directly drilling in from under the valve door!

Bang! Bang bang!

“Fire!”

Wei Na's shout shortened the reaction time of the security guards.

Three or four people fired at the same time, two people fumbled to pull the safety, the blade limbs raised by this Blade Beast had already swept across.

The middle-aged uncle who was repairing the circuit with his head down widened his eyes, and his upper body suddenly lost support. Before he could feel the pain, his body had already fallen downwards.

“Ah — —”

“Blade Beast!”

Screams, gunshots, the sound of flapping wings.

Wei Na emptied her handgun and turned to run. She had realized that the bullets from handguns and rifles, aside from slightly hindering the Bladebeast's movements, couldn't penetrate its exoskeleton!

Two members of the security team screamed in agony. The Bladebeast's gaze locked onto Wei Na, and it rushed forward with flapping wings, its body fully extended in the narrow passage.

"Dr. Wei, get out of the way!"

A somewhat familiar voice rang out.

Wei Na looked up and saw a group of figures rushing towards her.

The man at the head, wearing a black helmet and with a pair of mechanical prosthetic arms, was grabbing a metal pipe over three meters long, shouting as he rushed past Wei Na.

Lan Yuzai? The Good People Gang?

Don't go…

The metal pipe pressed against the Bladebeast's chest!

Lan Yuzai gritted his teeth and shouted, his body suddenly stopping, sliding backward from the force.

But behind him, seven or eight young people in sportswear had already rushed up, shouting as they hugged the back end of the metal pipe, barely managing to hold back the Bladebeast!

The Bladebeast slowly tilted its head, seemingly thinking, its vertical pupils expressing disdain.

Then, the white membrane on its face retracted on its own, revealing a horrifying maw.

Circles of sharp teeth looked like eyes, staring at Lan Yuzai and his underlings.

Ya—

A mental shockwave, visible to the naked eye, swept over them!

The men behind Lan Yuzai screamed simultaneously. Lan Yuzai, taking the brunt of the impact, gritted his teeth and groaned, his mechanical prosthetic arms gripping the metal pipe tightly, his muscles bulging!

Behind his helmet, blood appeared at his ears and the corners of his eyes, and he let out a meaningless cry.

Two figures rushed from behind.

It was Lin Xiong and Lin Yong, sent by Zhou Zhengde to take Wei Na to the thirteenth floor's shelter!

They darted in front of Lan Yuzai, each grabbing two miniature grenades, and while the Bladebeast was still recovering from releasing the shockwave and hadn't closed its mouth, they forcefully threw the grenades into its maw!

Boom!

Emerald blood splattered!

—These Bladebeasts, having evolved wings, were far less sturdy than the mutated Bladebeast that Wang Ji Xuan had encountered in the tunnel, and even had slightly weaker defenses than the low-level basic Bladebeasts. Their main evolutionary direction was mobility, aggression, and weight reduction.

The Bladebeast's corpse slowly crashed to the ground.

Lan Yuzai knelt on the ground, clutching the metal pipe, his eyes glazed over.

In front of him, Lin Yong and Lin Xiong were caught in the blast. One had almost all the skin on his back blown off, and the other had a piece of the Bladebeast's exoskeleton piercing his thigh.

The valve! The fire hydrant valve!

Wei Na suppressed the urge to vomit, dragging her exhausted body towards the valve.

The engineer uncle had grabbed the wires earlier. If they were connected, they should be able to temporarily bypass the burnt-out circuit?

Buzz, buzz.

The dense sound of flapping wings appeared in her ears. Wei Na trembled all over. Her mind was already at its limit. She lightly touched the two wires together and saw a faint spark.

There were Bladebeasts hovering outside.

More than one.

They were attracted by the corpses of their comrades inside.

Wei Na pressed the two wires together, constantly shouting in nervousness, tears almost welling up in her eyes. The valve trembled slightly, and there were still several sets of unconnected wires below.

Those Bladebeasts were about to rush in!

"Ah, ah!" Wei Na shouted in nervousness, tears almost welling up in her eyes.

Lan Yuzai, kneeling there, shook his head forcefully, his Adam's apple trembling. He lowered his head shakily and saw the faded pink talisman on his chest.

Lan Yuzai could just see that three mutated Bladebeasts were staring at him, staring at his mechanical arms.

They seemed to be wary.

Did they mistake his prosthetic limbs for the same thing as the Battle Maiden's mechanical arms?

Doctor Wei Na was standing right there.

Lan Yuzai stood up shakily, glaring fiercely at the Bladebeasts. He grabbed the grenade pouch from Lin Xiong's waist, took out a miniature grenade, pressed the release button, and charged forward, diving headfirst.

The three Bladebeasts dodged backward. Lan Yuzai stabilized himself on the outer platform, leaped up, and pounced on the nearest Bladebeast.

He put the activated miniature grenade back into the grenade pouch and suddenly opened his arms.

Tch.

A section of a blade limb pierced Lan Yuzai's chest.

Lan Yuzai's body twitched a few times, and his hands suddenly gripped the Bladebeast's leg limbs, pressing the grenade pouch against the Bladebeast's chest.

A series of somewhat embarrassing images flashed before his eyes, drifting past a dozen timid faces filled with helplessness.

'Ah, I didn't get a chance to hang out with the big boss.'

'Sorry, I used to be… not very sensible…'

Boom!

Wei Na was blown away by the surging flames, and the slightly swaying fire gate crashed down heavily.
