All the vanguard team sacrificed

 Qingzhou University.

Outside the sealed dormitory building.

The principal and more than ten security guards listened to the screams coming from inside the dormitory building, their faces turning pale, sweat pouring down, anxiously pacing in place.

When the patrol team arrived, the principal hurriedly greeted them with a relieved smile.

Li Yin led his team to the bottom of the dormitory building, looking at the locked and tightly closed doors from the outside, his brow slightly furrowed.

Listening to the cries for help coming from inside, his heart ached faintly, filled with anger.

Sealing off the entire dormitory building meant abandoning the students inside the building.

This method was too cruel.

It was also unfair to the students inside.

But Li Yin was very clear.

If the principal had not sealed the dormitory building at the first moment, perhaps Qingzhou University would be in chaos like Street 121.

The principal's decision to consider the bigger picture was not wrong.

"What is the situation inside the dormitory building now?"

Suppressing the anger in his heart, Li Yin asked the principal.

"All the cameras inside have been destroyed, and I don't know the specific situation."

"But based on the previous reactions from the monitoring room, zombies have spread to every floor."

The principal quickly replied, using his sleeve to wipe off the sweat on his forehead.

"Ah..."

Bang—

As soon as the principal finished speaking, a miserable scream suddenly came from above.

Everyone looked up and saw a student tightly embracing a snarling zombie, rolling out of the sixth-floor window. 

Under everyone's gaze, the student and the zombie crashed to the ground together.

The student immediately turned into a mass of flesh without any signs of life.

Although the zombie had a student cushioning its fall, when the back of its head made contact with the ground, it still caved in, blood and flesh splattering.

Despite such a severe injury, the zombie did not die.

It struggled to get up, waving its sharp claws, smelling the scent of living beings, and quickly charging towards the principal and the group.

Seeing this, the principal and the security guards were so frightened that their faces lost all color, and they turned and fled.

Li Yin and his team's hearts were also pounding wildly.

They had never imagined that the zombies would have such strong vitality.

As the zombie approached, everyone in the team quickly drew their guns, aiming precisely at the zombie's head and firing.

After the zombie's head exploded, it fell to the ground, breathless.

"Open the door, we need to go in and save people!"

Watching the tragic death of the student, Li Yin made a decision in his heart.

He could not stand by and watch so many innocent lives die before his eyes.

"No, once the door is opened, if the zombies inside rush out, the whole school will be doomed."

Shocked by the words, the principal quickly blocked the locked door.

The number of zombies inside the dormitory building was unknown, and the principal did not believe that Li Yin's team of five had the capability to handle all the zombies inside.

 Aooo—

Before Li Yin and the principal could argue, the howls of zombies suddenly came from the windows above.

Without giving them time to react, zombies jumped down from the second and third floors.

The three to four meters of height did not cause any harm to any of the zombies.

The moment they landed, they immediately locked onto their prey and sprinted towards their targets.

Just as the principal was about to escape, he was knocked down by a zombie, leaving deep claw marks on his back.

This scene happened too suddenly and caught everyone by surprise.

Seeing this, Li Yin and his team acted without hesitation, decisively firing their guns.

Every shot was precise.

Attracted by the gunshots, the zombies chasing the security guards immediately turned back.

From all directions, zombies rushed towards Li Yin and his team.

Inside the dormitory building, zombies continued to jump down from the windows and converge towards them.

Li Yin and his team tacitly formed a circle back to back, facing the incoming zombies, shooting frantically.

But as soon as one zombie fell, another one would leap forward.

"Captain, these monsters have intelligence, and their numbers are overwhelming. The five of us are no match for them. We need to retreat quickly!"

Seeing the zombies closing in, Wang Meng shouted to Li Yin.

"Retreat!"

Li Yin didn't hesitate and immediately ordered a retreat.

But before the words were even finished, a zombie happened to jump down from above them.

Reacting swiftly, Li Yin turned around and shot at the falling zombie.

Unfortunately, his speed was a step too slow.

Wang Meng was pinned down by the falling zombie, with its fangs piercing through his throat.

The zombie tore apart his combat suit with its sharp claws, leaving bloody scratches.

Ignoring the gunfire, the zombie suddenly darted towards the rest of the team.

"Retreat! Retreat quickly!"

Watching Wang Meng take his last breath, with zombies continuously jumping down from above, and more zombies closing in, about to surround them, Li Yin had no choice but to issue a retreat order once again.

He led the way and charged towards the exit.

However, the numerous zombies jumping down the stairs did not give them a chance to break through.

They launched an intense pursuit against Li Yin and his team's retreat.

Li Yin and his team fought desperately, relying on their teamwork and cooperation, continuously killing the approaching zombies.

Li Yin realized that the zombies, capable of jumping out from the second and third-floor windows, chose to attack them when they arrived.

It seemed like the zombies had been prepared long in advance.

Their goal was to wait for their arrival, catch them off guard, and eliminate them in one strike.

At the thought of this possibility, Li Yin shuddered.

He dared not imagine whether such a group of intelligent and coordinated monsters could be easily wiped out.

"Bang!"

At that moment, a gunshot suddenly rang out behind them.

Feeling a sharp pain in his back, Li Yin stumbled and fell to the ground.

Turning back, he saw Wang Meng, who was already dead, standing up again.

He raised his gun, aiming at Li Yin and the rest.

Three of his teammates immediately rushed to help Li Yin up, intending to charge out together.

"Go! Hurry!"

Seeing Wang Meng preparing to shoot again, Li Yin pushed away his approaching teammates without hesitation, roaring.

"Bang! Bang! Bang!"

Three consecutive gunshots rang out, hitting the three teammates, causing them to fall one by one.

Simultaneously, the approaching zombies pounced on them, using their sharp claws to tear through their skin.

With a wave of dizziness, one by one, the four lost consciousness.

When they opened their eyes again, they had all turned into unconscious zombies.

Relying on instinct, like other zombies, they began to infect and feed on the crowd inside Qingzhou University.

Qingzhou University was plunged into chaos...

Meanwhile,

In Street 121, the snack street, and the construction site, among other places,

The remaining nine teams of five from the patrol team were all surrounded by hordes of zombies.

There was no possibility of retreat.

Facing the relentless attacks of the fearless zombies, they retreated step by step.

Teammates sacrificed one after another, turning into infected zombies.

In the end, none of the members of the nine teams survived, all becoming part of the horde of zombies, engaging in carnage.

With the sacrifice of the ten teams,

No one knew that the outbreak of the zombie disaster was caused by nine deliverymen.

It wasn't until much later that the top officials of the Wuguo discovered clues from numerous videos online...

The news of the ten teams of the patrol team members turning into zombies was also spread by the fortunate survivors who witnessed it firsthand.

The internal panic in Qingzhou escalated once again.
