Doomsday police, please show your god/demon ID card.

Da da da!

Gunfire erupted in rapid succession, echoing wildly within the cramped inner city space, causing a painful ache in the eardrums.

Drones hovered overhead, while machine guns spat fire, sweeping down rows of zombies.

Explosions erupted one after another, Molotov cocktails slammed into the horde of corpses, and sticky flames spread everywhere.

However, the number of zombies was simply too great.

The black torrent seemed endless, completely ignoring the suppressive fire overhead, surging towards the inner city wall layer upon layer.

"roar!"

A large, muscular zombie suddenly leaped up and grabbed the edge of the wall.

A young police officer roared and slammed his gun down with the butt of his rifle.

The zombie's skull shattered, and its claws loosened.

Before the officer could catch his breath, two rotting arms reached out from under the wall and grabbed his ankles.

"what!"

The officer screamed, lost his balance, and was dragged backward by a tremendous force.

His comrade next to him reached out to pull him, but only managed to grab a corner of his clothes.

Under the watchful eyes of several people around, the figure fell into the horde of corpses below.

The screams stopped abruptly, without even a single drop of blood appearing.

"Hold on! All of you, hold on!" Wang Hu roared, his eyes bloodshot, his voice trembling with a sob.

The rifle in his hand spat fire, smashing the brains of a zombie that was trying to climb up.

The ammunition box next to him was already half empty.

The walls were shaking violently as countless zombies slammed their bodies against the base of the walls, producing dull, deafening noises.

Fine cracks have appeared at some of the wall joints.

Boom!

A loud bang.

Everyone stumbled.

A section of the city wall not far to Wang Hu's left finally succumbed to the relentless onslaught of the zombie horde and collapsed with a deafening roar.

Gravel and dust shot into the sky.

A gap more than ten meters wide was exposed to everyone.

"Roar!"

The roars of the zombie horde suddenly became louder, like sharks smelling blood.

The black torrent found its outlet and surged wildly through the breach.

Some survivors who had been organized to help move supplies from the rear were terrified when they saw this scene.

"The wall collapsed! Zombies are getting in!!"

"Run! Run!!"

"Get out of the way! Move aside!"

The crowd instantly descended into chaos, with cries and screams echoing from behind.

Someone turned and ran, but ended up knocking down the person next to them and tripping over themselves.

A zombie burst out of the gap, pounced on the fallen man, opened its blood-red maw, and bit down hard on his neck.

Fresh blood gushed out.

The man's scream lasted only two seconds before turning into gasps and gasps.

More zombies poured in, engulfing the still convulsing body.

The situation was completely out of control.

"Damn it! How did it collapse again!" Wang Hu cursed, just about to lead his men to plug the gap.

But another figure was faster than him.

Su Yan had somehow ended up near the gap, her face still pale and her body swaying precariously.

She took a deep breath.

Deep within his pupils, a silver light exploded like a supernova, then quickly dimmed and turned gray!

"Ugh—!"

She let out a scream and, with all her might, pushed the surging tide of corpses forward!

A transparent ripple, almost visible to the naked eye, burst forth in a fan shape from in front of her.

The horde of corpses that was pouring in through the gap suddenly stopped moving, as if a pause button had been pressed.

They stood there blankly, a struggle flashing in their scarlet eyes.

Then, a bizarre scene unfolded.

The zombies closest to Su Yan suddenly turned around and roared as they pounced on their kind behind them.

The horde of zombies surged in, but there was a very brief pause and period of chaos!

"Now's the time!" Seizing the opportunity, Wang Hu roared, "Suicide Squad, inject your potential-enhancing drugs! Charge in with me!!!"

His voice was like thunder, clearly audible amidst the chaos of the battlefield.

Without the slightest hesitation, the thirty carefully selected veteran police officers simultaneously pulled syringes from their tactical vest pockets and plunged them into their thighs.

Potential-enhancing drugs are not plentiful.

Chen Ming worked so hard that his hair almost fell out, but he could only barely gather enough for thirty people's doses.

"Ughhhh!"

The suicide squad members, injected with the drug, let out painful screams.

The veins on their necks bulged, the blood vessels under their skin became clearly visible, and their eyes quickly became bloodshot and turned bright red.

A violent force exploded within them.

On the other side, Su Yan swayed and fell straight backward, but was caught in time by a quick-thinking medic.

Excessive consumption of mental energy is even more terrifying than the side effects of injecting potential-enhancing drugs.

Her injury had not fully healed; she was playing while injured.

After that attack, he quickly fell into a weakened state.

"kill!!!"

Wang Hu was the first to rush out, crashing directly into the horde of corpses.

He used the rifle in his hand like a club, each swing accompanied by a whistling sound as it tore through the air.

The zombie's head was easily smashed like a watermelon.

The other officers, who had been injected with the drug, followed closely behind, crashing headlong into the horde of corpses pouring in through the gap.

They used their bodies, their weapons, their flesh and blood to forcibly plug the gap that was more than ten meters wide.

Minced meat flew everywhere, and black blood splattered.

The battle entered its most primal and bloodiest phase.

Everyone knew that this was just a stopgap measure.

The effects of the potential potion can only last for a maximum of fifteen minutes.

Once time passes and the drug's effects wear off, these thirty police officers will instantly lose all fighting ability.

At that point, the breach will reopen, and the entire base will be completely destroyed.

Tang Long brandished his double whips, sweeping zombie after zombie toward the foot of the city wall.

Out of the corner of his eye, he saw the breach in the city wall, and his heart was burning with anxiety.

Drone bombing, traps and roadblocks, fortifying the walls, potential-enhancing drugs...

All the cards have been played.

Faced with such a massive zombie horde of 100,000 people, the East District base was far too weak.

Time passed by, second by second.

With fifteen minutes about to pass, the officers on the front line began to move more slowly.

Tang Long glanced at the system interface.

[Order Points: 42876]

In two consecutive waves of frantic defensive counterattacks, coupled with the contributions of Zhao Fan and others yesterday, the team achieved remarkable results.

The Order Points have already exceeded the 30,000 points required for the upgrade, and there are even quite a few left over.

His mind raced, and a crazy idea formed in his head.

He picked up the walkie-talkie, his voice hoarse from nervousness, yet carrying an undeniable resolve.

"Everyone, listen up!"

"Abandon the inner city walls and immediately retreat to the main building of the police station!"

"Repeat! Everyone, retreat to the police station!"

Zhao Fan, who was directing the survivors to throw Molotov cocktails from the top of the wall, was stunned when he heard the order.

He grabbed the walkie-talkie and shouted incredulously, "Team Leader Tang! Retreat to the police station? That's a dead end! There's no way to escape!"

Tang Long's short voice came through the walkie-talkie.

"Never mind that, just follow orders!"

Zhao Fan gritted his teeth, looking at the already crumbling defense line.

"Everyone retreat! Retreat to the main building! Quickly!"

The police station was already packed with people.

The space, spanning over 400 square meters, was crammed with more than 3,000 survivors.

The main building's reception hall, corridors, staircases, every office, and even the officers' quarters, which had previously been closed to the public, were all packed with people.

The air was thick with fear and despair.

Some people had been pushed to the edge of the rooftop, looking down in terror.

Wang Hu led the thirty exhausted suicide squad members, whose eyes were beginning to glaze over, and stumbled into the main building's entrance.

Bang! Crash!

The thickened alloy gate slammed down.

Followed by.

Boom!Boom!Boom!

The sounds of zombies crashing came from all directions.

The entire police station building swayed slightly under the continuous impact.

"We're all going to die..."

"Mom...I'm scared..."

"It's over, it's really over..."

A sense of despair spread through the crowd.

The sounds of children crying, women sobbing, and men cursing mingled together.

Tang Long squeezed through the crowd and arrived at the center of the hall.

Bring up the system interface and focus your attention on the upgrade button.

He didn't decide to return to the police station on a whim; rather, he was thinking of the scene when the system was first upgraded.

At that time, the Dongcheng District base was just a dilapidated police station.

Until the system was introduced, the police station underwent a complete transformation.

A flash of blue light, and all the zombies turned to ashes in an instant.

That's how he managed to escape death.

This time, he was betting that the system upgrade would produce the same clearing effect!

Tang Long took a deep breath and no longer hesitated.

"System, upgrade!"
