Zhang Chen focused on the syringe filled with yellow liquid in his hand.

[Elementary physique potion can make your physical fitness reach an abnormally strong state! 】

The physical level of ordinary survivors is divided into five levels: weak, ordinary, strong, extremely strong, and human body limit.

After reaching the limit of the human body, it will enter the awakened stage.

The Evolver stage has a classification form for the Evolver stage, which cannot be viewed currently.

But you can turn on talents to gain superior abilities!

Zhang Chen is currently in an ordinary survivor's physique.

Since this potion will directly reach an extremely strong level regardless of your physical fitness.

Of course, the sooner you use it, the better!

Even if Zhang Chen now starts to consciously exercise every day.

Improve your own strength to a strong level.

Even after being injected with the medicine, he was still upgraded to an extremely strong level.

So there is no need to bother!

"Use it immediately!"

Zhang Chen's hands seemed to have learned to find intravenous injections by nature.

Operated skillfully.

Slowly push the yellow liquid into the vein.

In an instant, a hot feeling traveled along the blood circulation throughout the limbs and bones!

The pain felt like muscle tearing wherever it passed!

Zhang Chen was in so much pain that he wanted to scream loudly.

But he held back!

Thousands of zombies roam the streets outside.

With such a voice, once the zombies are provoked.

Then he will definitely die.

No medicine can save myself!

After about five or six minutes, the burning sensation slowly disappeared.

Afterwards, Zhang Chen felt relaxed all over his body!

The senses also seem to be sharper than before.

My whole body is full of strength!

He waved his fire ax.

The fire ax originally felt a little heavy.

Now it feels as light as nothing in my hand!

Hearing also seems to be sharper than before.

Because he suddenly heard a faint cry for help.

Moreover, this voice suddenly reached my ears in the middle of the sentence.

"(Is there anyone here to save)... me!"

"Ah~ don't come here!"

"You monsters!"

"Is there anyone nearby, ah!~"

Judging from the sentence fragments, this voice has been shouting for a long time It's been a while.

It's just that Zhang Chen's hearing was not that sensitive before using the potion.

That's why I caught it now!

Zhang Chen made a careful distinction.

The sound came from outside the window.

Zhang Chen walked to the window.

He did not stand carelessly in the center of the window.

Any action that might attract the attention of a zombie is foolish!

Zhang Chen stood on one side of the wall and looked out.

The real estate agency is located behind a residential complex.

The shouting survivor was standing about a hundred meters away, on the rain cover above the door of a unit.

It was a woman wearing a form-fitting, low-cut dress.

It seemed that he was attending some banquet and was teleported over.

What kind of clothes everyone wore before traveling through time will be what they wear after traveling through time.

Zhang Chen was wearing sportswear before.

Come here and wear sportswear too.

If it weren't for a pair of sneakers under my feet, I wouldn't have been able to run a distance of tens of meters in just a few seconds!

And this woman's clothes are obviously not suitable for sports.

There is also a pair of high heels on her feet.

It is easy to sprain your feet when walking on uneven roads.

Surviving in this extreme apocalyptic environment is not much different from dying.

And the most fatal thing is that her position was originally very safe.

But after such a scream, all the zombies wandering in the community were attracted.

Instead, it became the target of public criticism!

There were seven or eight zombies in total, all gathered at the door of the unit.

One by one, they raised their heads, stretched out their hands, and roared in a low voice!

"What a stupid woman!"

"Don't you know that sound can attract zombies?!"

"But... this seems to be an opportunity!"

Zhang Chen stood by the window and observed for a while.

These zombies are completely attracted to the woman's voice!

His face was facing the direction of the unit door and his back was facing Zhang Chen.

It's a good opportunity for a sneak attack!

It's just... I don't know if the zombies here are the same as the zombie movies Zhang Chen has seen before!

They are all particularly sensitive to sound and vision!

Is it possible to find humans based on smell? !

If that's the case...if he takes action rashly, he will definitely end up losing his life!

It's the end of the world now!

And you only have one life!

You must be careful!

Just when Zhang Chen was carefully observing the situation!

The prompt appears again!

[Zombies are sensitive to sharp sounds, now is a good time to harvest! 】

The content that appeared in the prompt just answered Zhang Chen's question!

Since the prompt says there is no problem, it's easy to handle!

An opportunity to kill seven or eight zombies in an instant!

The system has said before that by killing zombies and mutant creatures, you can obtain energy crystal cores that make people stronger!

Don't miss this opportunity!

With a thought, Zhang Chen equipped himself with a tempered helmet, explosion-proof shield and fire axe.

Then we walked to the back door of the real estate agency.

The front door of the real estate agency is a glass door facing the street.

The back door is a security door that leads to the inside of the community!

[The anti-theft door has aged. If you open the door too quickly, it will make a sharp metal friction sound! 】

The prompt appears in time!

Zhang Chen's hand has already grasped the door handle of the security door.

He let out a long breath, and then carefully pushed the security door open a gap.

Squeak!

There was a sound of friction between the metal door and the slightly deformed door frame.

Fortunately, the sound is not loud!

Even so, the zombies in the distance still paused slightly.

Then I was attracted again by the woman in front of me who screamed endlessly!

call! What a risk!

Just a slight push almost attracted zombies!

If there had just been a sudden push, the sound echoed in the empty residential area.

I guess the next one to be trapped by the blocked door will be me!

Thanks for the tip!

Zhang Chen gained experience and continued to push the door forward little by little to open a gap that could accommodate one person.

Then he ducked and squeezed out of the gap.

"Hey, I'm here, help me!"

The woman was already shouting a little tired.

Seeing Zhang Chen, he quickly shouted excitedly.

Just with this voice, the zombies are attracted to him!

Zhang Chen's backhand is a thumbs up!

He didn't dare to neglect, holding a blast shield in his left hand and a fire ax in his right hand.

While looking around vigilantly, he moved forward quickly.

Soon he arrived behind the zombie group.

"Be careful, be careful, don't get caught by these zombies!"

"I've seen zombie movies. If you are bitten or caught, you will turn into a zombie!"

the woman screamed loudly.

Zhang Chen ignored the woman.

All the energy and attention were focused on the group of zombies in front of him.

Be sure to kill with one hit!

Thinking of this, Zhang Chen put the explosion-proof shield on his chest and rounded the axe.

He fiercely chopped the nearest zombie on the back of its head!
