Still hoarding supplies in the apocalypse? I'll just go on a killing spree and looting!

Lin You closed the door and took the mantis knife off her back, leaning it against the sofa armrest.

Mu Xue's footsteps gradually faded away in the stairwell.

She sat on the sofa, glanced at An'an who was still fast asleep in the bedroom, and raised her right hand to make a gesture in the air.

The system interface pops up.

The blue light illuminated Lin You's slightly pale face.

The top left corner of the status bar displays the system's main level as lv.1, mental strength as 78/100, and technology points as 150.

Technology points have increased!

Lin You remembers that she used to only have fifty technology points, but now she has one hundred and fifty.

Is it by dismantling alien beasts or recycling items that the technology points increase?

Lin You didn't know that having survived five years in the apocalypse, she didn't care much about the system.

The only difference is that this system involves dismantling alien beasts to obtain equipment and recycling industrial products so that you can create one yourself when needed.

The system is just a tool; she could survive for five years in the apocalypse without it.

It's all about relying on yourself.

If it weren't for Mu Xue and her group, they probably would have lived even longer.

She opened the Blueprint Library window in the lower right corner, where five rows of tech tree branch icons were neatly arranged—Weapon Workshop, Machinery Workshop, Gene Lab, Energy Workshop, and Construction Workshop.

The first two branches already have several lit icons: the Weapon Workshop and the Mechanic Workshop.

There are blueprints for firearms and drones that Linyou has recycled.

But the row of gene labs was still dark, with only the first node flashing a faint blue light.

That node is labeled T0, and below it is marked "Basic Potion".

She tapped it, and a message popped up on the screen: "Host detected entering the Gene Lab branch for the first time. Unlocking T1 requires submitting a basic biological material sample—Beast Marrow Fluid (quality excellent or higher)."

She glanced at the materials warehouse, which even contained rare beast marrow.

From the first monstrous beast she slew on the rooftop, the decomposed remains of each beast's corpse lay quietly under the organic biomass classification label.

She confirmed the submission.

Rare beast marrow fluid was deducted from the material library, and then above the icon of the gene laboratory, an extremely thin blue light lit up from the center of the node, slowly extending along the branch lines.

The outlines of those gray icons began to emerge, like a star map being gradually lit up.

Healing potions, antidotes, temporary petrification potions, and temporary enhancement potions.

Not only that, the blue light continued to spread until it approached the location of the next T2 node.

Because they are incredibly close.

Is this the effect of rare beast marrow fluid?

Lin You could see some potions that should have triggered the next stage.

The next stage of the potion is permanent physical enhancement, as well as those higher-level nodes that are still shrouded in mist and whose labels are not yet clear.

To unlock the next stage, you need to be at level 2.

Lin You didn't know how she reached level two, so she could only look away.

My gaze fell on the healing potion icon on the interface, which lit up.

The label below the healing potion indicates the required materials: 1 piece of beast blood. Estimated effect: Heals a certain amount of injuries, but cannot completely heal moderate injuries such as severed limbs.

Lin You raised an eyebrow. There's a medicine that can regenerate severed limbs?

After hesitating for a moment, Lin You clicked on the "Make" option.

There were about thirty portions of the beast's blood.

Some mythical beasts are broken down into one or two pieces, while others are broken down into five or six pieces.

Lin You doesn't usually care about the materials from these dismantled items; what she wants are equipment like the Mantis Knife and the Bone Dagger.

These materials now appear to be very important.

The progress bar for the healing potion started moving.

This was the first time she had used the gene lab's manufacturing capabilities, or even the system's manufacturing capabilities.

Lin You could even hear the extremely faint electrical sound of the system running, not from her ears, but from the light gold tattoo on her arm.

Fifteen seconds later, a glass tube landed in her palm.

The tube is only as thick as a thumb, even thinner than a regular syringe.

The two ends are sealed with metal hoops, and the middle is a section of light green liquid. When light shines through it, you can see tiny fibrous suspended particles slowly rotating, like a shattered aurora.

The liquid surface has a very thin, oily sheen, and when tilted, it leaves a slow trail as it slides down the tube wall.

Is this drinkable?

Lin You frowned and twisted open the potion, releasing a whiff of odor.

A strange, grassy smell, mixed with the scent of flesh and crushed fresh leaves.

The smell reminded her of a patch of grassy water that she had walked through in the wasteland in her previous life, where dark green sap would seep out with every step she took.

She brought the tube close to her mouth and paused for a second.

The next moment, Lin You had already tilted her head back and finished drinking the potion in her hand.

The liquid stung slightly as it slid down my throat, like swallowing a small piece of crushed ice.

Then comes the heat.

A surge of hot air rose from my stomach and spread throughout my body along my blood vessels.

Her fingers began to go numb, and the pain at the broken bone intensified dramatically within seconds—it hurt more than when it broke, as if someone had set fire to her bone marrow.

The flames spread along the seams of the bone, burning all the way from the fracture point to the fingertips.

Her right hand gripped the sofa armrest tightly, her knuckles turning white.

Then she felt her bones move.

It's not a metaphor; it's really moving.

She could clearly see the edges of the broken bone being pushed together by the writhing muscles, and the bone fragments moving slowly within the muscles, as if being attracted and rearranged by an invisible magnet.

It was accompanied by a sharp, throbbing pain, followed by a pulling sensation, and then a tightening.

She gritted her teeth and remained silent.

After about two or three minutes, the excruciating pain began to subside. In its place came a warm, slightly tingling sensation that spread from the broken bone.

A feeling of exhaustion suddenly washed over me.

Lin You closed her eyes slightly and fell into a deep sleep.

I don't know how much time passed when I woke up again.

The fog outside was still thick and gray, and my head felt a little dizzy.

I sat up instinctively and moved my left hand fingers.

The five fingers bend in sequence, and the joints make a slight clicking sound, but there is no stiffness.

She pulled her hand out of the suspenders and rotated her wrist.

There was still a slight, dull pain at the break in the bone, but it no longer affected my mobility.

This...! Am I cured?

It's important to know that it takes 100 days, or three months, to recover from a bone or muscle injury.

A lot can happen in three months; you might not even get through a month safely, let alone three months.

This explains why survival is extremely difficult for lone wolf survivors after the apocalypse.

Only by relying on small groups can powerful organizations survive in the long run.

Any accident, injury, battle, illness, lack of food...

Even if it's just a lack of rest.

All of these could lead to death.

There are almost no lone wolf survivors after the apocalypse, not even humans with superpowers.

Those lone wolves who cower in their own shelters, guarding their stockpiled supplies, rarely have a happy ending, except for spatial ability users like Mu Xue.

A strange beast with a keen sense of smell, a group of envious survivors with ill intentions, and all sorts of unexpected events.

Each one is extremely deadly.

Lin You's mind was racing, and for a moment she didn't know where it had gone.

"Knock knock"

A knock sounded on the door, and Lin You put her arm back in the bandage and hung it around her neck.

He got up to open the door.
