Henry focused on the syringe in his hand, filled with a yellow liquid.
[Basic Physical Enhancement Potion, can elevate your physical condition to an extraordinarily strong state!]
The physical levels for ordinary survivors are categorized as frail, normal, strong, extraordinarily strong, and human limit.
After reaching the human limit, one enters the Awakened phase.
The evolutionary stage has its own classification form, which is currently not accessible.
However, it can unlock talents and grant extraordinary abilities!
Currently, Henry is at the normal survivor's physical level.
Since this potion will boost any physical level directly to an extraordinarily strong state,
it is obviously better to use it sooner rather than later!
Even if Henry were to start exercising consciously every day,
and raise his strength to the strong level,
the injection of the potion would still upgrade him to the extraordinarily strong level.
So there's no need to do things the hard way!
"Use it immediately!"
Henry's hands seemed naturally adept at finding veins for the injection.
He operated smoothly,
slowly pushing the yellow liquid into his vein.
Instantly, a burning sensation spread through his limbs and body via the bloodstream!
Wherever it traveled, the muscles felt a tearing pain as if they were expanding!
Henry wanted to scream out in pain.
But he restrained himself!
Thousands of zombies roamed the streets outside.
A shout from him could attract the zombies.
Then he would undoubtedly die.
No potion could save him then!
After about five or six minutes, the burning sensation slowly faded.
Afterwards, Henry felt an overall sense of relief!
His senses seemed sharper than before.
His body was filled with strength!
He swung the fire axe in his hand.
What had felt slightly heavy before,
now felt as light as a feather in his grasp!
His hearing also seemed sharper than before.
Because he suddenly heard a faint cry for help.
And this voice started mid-sentence, suddenly reaching his ears.
"(Is anyone there to save)... me!"
"Ah~ don't come over!"
"You bunch of monsters!"
"Is anyone nearby, ah!~"
From the way the sentences broke off, it seemed that the voice had been calling out for some time.
It was just that before using the potion, Henry's hearing wasn't so sensitive.
So only now did he catch it!
Henry carefully discerned the direction.
The voice was coming from outside the window.
Henry walked to the window.
He didn't carelessly stand right in the center of the window.
Any behavior that might attract the attention of zombies was foolish!
Henry stood to one side of the wall, leaning out to look.
The back of the real estate agency faced a residential area.
The screaming survivor was standing about a hundred meters away, on the awning over an apartment unit's door.
It was a woman dressed in a form-fitting, low-cut evening gown.
It seemed like she was at some kind of party when she was transported here.
Everyone wore the same clothes they had on before the transition.
Henry was wearing sportswear before, and he arrived in sportswear.
If not for his sneakers, he wouldn't have been able to run several tens of meters in a few seconds!
But this woman's outfit was clearly not suitable for physical activity.
She was also wearing a pair of high heels.
Uneven ground was enough to cause a twisted ankle.
Surviving in such extreme apocalyptic conditions was not much different from a death sentence.
Moreover, what was most deadly was that her location had been safe.
But after all her screaming, she had attracted all the zombies roaming around the residential area.
Now, she had become a target!
There were about seven or eight zombies, all gathered at the entrance of the unit.
Each one tilted their heads back, stretching out their arms, and growling softly!
"What a foolish woman!"
"Doesn't she know that noise attracts zombies?!"
"But... this could also be an opportunity!"
Henry stood by the window, observing for a while.
The zombies were completely drawn to the woman's voice!
Facing towards the unit door, their backs were turned towards Henry.
It was a good opportunity for a sneak attack!
Just... Henry wasn't sure if these zombies were like those in the zombie movies he had seen before—
especially sensitive to sound and sight!
Could they possibly track humans by scent?!
If that were the case... making a rash move would certainly be like delivering his head on a platter!
This is the apocalypse!
And there is only one life to live!
Caution is paramount!
As Henry was carefully assessing the situation, a notification appeared again!
[Zombies are sensitive to sharp noises, now is a good time to harvest!]
The content of the notification answered Henry's doubts!
Since the notification indicated no problems, that made things easier!
An opportunity to instantly take down seven or eight zombies!
The system had mentioned before that killing zombies and mutant creatures would yield energy cores that enhance one's strength!
An opportunity not to be missed!
With a thought, Henry equipped his tempered helmet, riot shield, and fire axe.
Then he moved to the back door of the real estate agency.
The front door of the agency was a glass door facing the street.
The back door was a security door leading to the interior of the residential area.
[The security door is old; if you open it too quickly, it will make a sharp metal friction sound!]
The timely notification appeared!
Henry's hand was already on the doorknob of the security door.
He took a deep breath, then carefully pushed open a crack in the security door.
Creak!
A sound of metal scraping against a slightly deformed door frame came out.
Fortunately, the sound wasn't loud!
Even so, the distant zombies paused briefly in their actions.
Then, they were once again drawn to the woman who kept shouting.
Phew! That was close!
Just a gentle push almost attracted the zombies!
Had I pushed it suddenly, the sound would have echoed through the open residential area.
I probably would have been the next one trapped at the door!
Lucky for the notification!
With the experience gained, Henry continued to slowly push the door open just wide enough for one person to slip through.
Then he squeezed out through the gap.
"Hey, I'm here, help me!"
The woman, already weary from shouting, saw Henry and urgently cried out louder.
With her volume, she kept the zombies firmly attracted.
Henry gave a thumbs up without looking back.
He couldn't afford to delay, holding the riot shield in his left hand and the fire axe in his right.
While vigilantly scanning his surroundings, he moved quickly.
He soon arrived behind the group of zombies.
"Be careful, make sure you're careful, don't let these zombies catch you!"
"I've seen zombie movies, if you get bitten or scratched, you'll turn into a zombie too!"
The woman screamed loudly.
Henry ignored the woman.
All his focus and attention were on the group of zombies in front of him.
He had to kill them in one strike!
With this in mind, Henry shielded his chest with the riot shield and swung the axe in full circle.
He fiercely chopped down at the back of the nearest zombie's head!
