Chapter 604 Union

"Should I let you in on the action?"

Tanya smiled when she heard the speech. "If I go to war, who will fly the helicopter?"

This is a very embarrassing thing.

Although Tanya can fly a helicopter, this is one of her necessary abilities as a special forces soldier.

This ability cannot be taught to others.

Just as American soldiers cannot mobilize soldiers to drive cars, engineers cannot teach American soldiers to repair machines.

These skills of Red Alert fighters cannot be taught to each other.

In the past few days, Lu Xuan and Tan Ya have learned to fly a helicopter, but he is also very busy on weekdays.He doesn't have much time to study, and he doesn't study very quickly.

If he was in a wide area, Lu Xuan might fly a helicopter, but now in the urban area, there are tall buildings everywhere.Maybe a person will accidentally fall into the plane and ruin the person.

At the airport base, there are a few people who can fly the helicopter, but they used to be Long Ye's people.Lu Xuan was worried about these people.

So for now, Tanya is the only one who can fly the helicopter here.

Therefore, he can only maintain the strongest fighting power here.

After all, the Red Police soldiers are very important, but the safety of Lu Xuan himself and his younger sister Lu Shanshan is more important.

At this time, the two Red Police units also began to attack the fourth and second floors respectively.

"Bang bang..." Gunshots began to ring out frequently.

There are zombies on the second and fourth floors, but the number is still very small.There are hardly 100 people on each floor.

This strange situation made Lu Xuan frowned again.

In this case, how many zombies can be hidden on the third floor alone?

Even if all the zombies are head-to-head and crowded, it can be packed with thousands of zombies at most.Compared with the tens of thousands of dead bodies, this number is a bit too small.While Lu Xuan was still wondering, a sudden change happened on the fourth floor!
A large number of zombies suddenly swarmed out from several corridors, roaring frantically at the red police soldiers.They move fast one by one.They are all advanced zombies!There's a zombie on the third floor!The corpse hiding on the third floor finally chose to act at this time!
Under Lu Xuan's command, the Red Police soldiers guarding the corridors have been trapped.Although the zombies rush out fast, the bullets that counter them are even faster.

The advanced zombies swarming in the corridors have no room to dodge and move, and roaring bullets can easily hit their heads.

Advanced zombies are very different from regular zombies.They are faster and more sensitive.They can use their speed to dodge muzzles to avoid damage.

However, in the crowded and narrow environment of the teaching building, the speed advantage of advanced zombies is obviously limited.

Even if their numbers were doubled, they wouldn't pose much of a threat to the Red Guard soldiers who got stuck and shot.

"Roar!" A sudden roar changed Lu Xuan's expression.

His all-too-familiar voice, when the giant zombie roared!

Among the two advanced evolved zombies, one of them can be determined to be a giant zombie!

The zombies downstairs are still rushing up.Dozens of advanced zombies were knocked down.The huge zombie took the lead in launching a fierce attack upstairs!
"Keep in formation, everyone retreats, don't get entangled with huge zombies."

With the firepower of American soldiers and mobilized soldiers, it is impossible to effectively kill giant zombies.The narrow environment of the teaching building is also a limitation for the giant zombie itself.As long as we retreat in battle, retreat along the fourth floor to the auxiliary building, and then retreat outside the building, there will not be much damage.

If the giant zombie dares to rush out with it, the multi-purpose infantry vehicles and heavy soldiers waiting outside the building will kill it in the first place!But just then.

"Ah!" Another scream made Lu Xuan's face change drastically.

"Big-headed zombie!" Lu Xuan almost squeezed these four words out of his mouth.

All the red police soldiers guarding the corridor stood motionless as he spoke.

"Boom!" The huge zombie waved its huge fist, smashing several red police soldiers into a pulp in an instant!

Lu Xuan's Red Police fighters were also among them.

When the huge zombie hit him with a fist swing, Lu Xuan saw a flying figure lying behind the huge zombie.

It was a skinny zombie with a big head!

"Retreat! Retreat!"

Big-headed zombies and giant zombies work together, which is definitely the worst situation!
The red police force on the fourth floor began to evacuate quickly.

Fortunately, unlike the big-headed zombies in S County Hospital, the environment here is closed, and the sound wave effect is maximized.

So most red police soldiers can move on.

However, the continuous sound attack of the big head zombies affected the red police soldiers.The Red Police fighters of the air command clearly stated that the physical conditions of the Red Police fighters who heard the screams on the fourth floor were abnormal to varying degrees.While they don't have full control over their movements, they also make it difficult for them to move, and their speed is greatly affected.

Red police soldiers are affected, but zombies are not.The advanced zombies passed through the huge zombies one by one, and knocked down the red police soldiers one after another frantically.

Seeing the increasing casualties of the Red Police soldiers, Lu Xuan scolded severely, but now is not the time to vent.

"The troops on the second floor! Kill the third floor right now! The location of the supply box has been sent to you via radar! Now two advanced evolved zombies are chasing the Red Police soldiers upstairs. Take this opportunity to take out the supply box!"

Zombies are not monsters guarding treasure.They are not interested in supply crates.For them, hunting humans is the most important thing.

Currently, a large number of zombies are gathering on the third floor, this is the best time to grab supply boxes!
The red police fighters on the second floor immediately rushed to the third floor.Several three-star American elite soldiers took the lead.The M249 in his hand kept spraying flames, blowing up all the zombies.

A group of people entered the third floor and soon found a green supply box in the classroom.

"Commander, the supply box has been found."

Ai Wa's voice made Lu Xuan heave a sigh of relief. "Get it out now!"

No problem with the army wave downstairs, but the real trouble is the red police force upstairs!

These two advanced zombies are stuck with them!
Red police soldiers fight, retreat and keep shooting, but huge zombies open the way in front of zombies.

Most bullets were stopped by swollen muscles.

Ordinary ammunition has too little lethality against giant zombies.

To make matters worse, the red police soldier tripped underfoot and was knocked over by the advanced zombies as they were startled by the constant screams of the big-headed zombies.

In just a few minutes, the red policeman's injury made Lu Xuan's face turn blue and his heart ache.

But in the end, the red police soldiers withdrew to the suspended corridor.
