Exit Building 7 from 201 and enter Building 6.

Lin Feng came to room 602 first, and the door of the master bedroom was locked.

There was a faint roar from inside.

Opening the door, the female zombie sat on the bed,

Pull the nylon braided rope tied to your feet.

The freshest corpse of Brother Hao has been gnawed by it and only the skeleton remains, and some of the spoiled husband's brain and internal organs have also been disposed of.

In one day, eating so much fresh meat,

Her belly didn't look bloated,

On the bed, there was only a little yellow-black excrement.

The digestive system of zombies is unusually good.

Not only anti-hunger, but also eaten.

Fresh flesh is a priority,

And the same kind is only the last option to maintain functioning.

Although the brains of zombies have shrunk,

But the survival strategy still follows the best plan.

Under the action of the virus,

They give up thinking, feelings, wisdom,

Instinct drives survival and evolution.

In a way,

The way of zombie mutation is more competitive.

The female zombie in front of her, after eating so much flesh and blood, not only recovered her arms that had been broken by Lin Feng, but also saw the crazy proliferating muscles and wriggling blood vessels under the gray-white skin.

The scars and bruises of the insults in front of him,

And overnight, they all disappeared.

While repairing the wound, it is slowly getting stronger.

The cloudiness in the blood-red eyes is gradually dissipating.

The moment it saw Lin Feng, it was stunned,

Then he retracted his smile and made a scared look,

Curled up in the pile of corpses, his eyes twinkle.

Lin Feng squatted down and observed her carefully.

It is obvious that the emotional reaction of the zombies is returning to normal......

From the previous dementia-like, it has become smart.

Ordinary zombies, such as walking corpses,

After adequate food is available and the infection deepens,

already has the intelligence of a four- or five-year-old child.

They know what it means to be afraid,

It can also restrain bloodthirsty desires.

Lin Feng really wanted to pry open its brain and see if there were any crystals inside.

Zombies are taking a new evolutionary path.

Abandon the heavy burden of the brain and return to the original.

After trying everything to strengthen the body,

Then condense wisdom and assist survival.

It's scary,

After giving up the brain,

Their ability to adapt to their environment, and how quickly they adapt, far exceeds that of other survivors.

and they are considered survivors of their prey......

It's the goal of evolution.

It's like the relationship between a cheetah and an antelope on the steppe...

The female zombie in front of her, before she had yet evolved to a first-level form, had already made Lin Feng feel a trace of pressure.

Slowly stand up,

Tied the nylon rope to the zombie's feet,

It's more secure.

When I closed the door and was about to leave,

Lin Feng still felt that it was not safe......

Turn back, pick up the knife, and smile.

Put the sharp teeth and fangs of the female zombie,

Pry loose one by one and pull out the ......

optimization of the facial nervous system,

This increases the pain sensation accordingly.

The female zombie howled in pain......

Lin Feng held his breath and patiently extracted his teeth.

And the full length of the tooth is beyond imagination.

From the gum to the top of the jawbone, the growth part is as much as 5 centimeters.

This is obviously more than normal human teeth.

In order to better gnaw on flesh and blood, zombies have evolved stronger biting muscles and cut teeth.

Lin Feng couldn't help but doubt,

If a certain surviving army clears the way with thermal weapons,

The zombie tide against it......

Will hardened bones evolve?

With adrenaline......

The overwhelming speed zombies,

Fearless of bullets and death, from all sides,

Towards the crowd......

I shudder to think about it......

In the game, I can't hold it with a gun.

After transforming into the ultimate hunter, you have the power to fight.

The sense of urgency brought about by the crisis urged Lin Feng to act.

After leaving only the molars for the female zombies to gnaw,

Lin Feng closed the door and locked the iron door outside.

I was going to go to Building 5,

After thinking about it, I decided not to take this risk.

Go back to Building 7 and go to the ground floor.

Near noon, the zombies outside were roasted by the sun, and they hid under the trees one after another, lying on the ground weakly.

Lin Feng opened the big iron gate at the entrance of the entire building.

The clicking sound sounded slowly......

A few zombies with good physical strength and good hearing,

Looking for the sound, he quietly groped his way through.

Living like discovering an opportunity,

People who sneak around on their own and make a fortune in a muffled voice.

It's a pity that this kind of cleverness has become their end.

Lin Feng sat at the gate, stabbing a child.

These smart zombies, the early they are solved, the less risk.

I cut down seven in a row, and no zombies came,

Lin Feng was reluctant to close the door,

Pituitary gland removal surgery.

And under the green belt between the buildings,

A few zombies hid behind a big tree,

Silently watching all this.

Witnessing the death of too many of his kind,

The buildings in front of them, have been them,

The subconscious mind judges that it is a dangerous place......

From the moment wisdom is born,

The first thing you realize is the danger around you.

There are still relatively few smart zombies,

The result of their evolution is also naturally screened.

Those who survive are the smartest.

Lin Feng didn't know that he had become a terrifying killing god in the eyes of zombies, and he was observing the changes in zombies.

Unlike the ordinary zombies in the house,

The zombies who have been basking in the sun outside for a long time, their skin has changed from grayish white to black and yellow,

And it's getting darker and darker.

The pore sweat glands of the skin gradually disappear......

Instead, a scaly hard layer of keratin grows......

Especially on the neck that is baked by the scorching sun,

The skin is covered with large scales.

This made Lin Feng think of reptiles,

Especially lizards.

Very drought-tolerant, hard-working animal.

Without sweat glands, there is no waste of body fluids.

And the other benefit it brings,

It is to prevent the pituitary gland, which grows at the back and bottom of the brain, from being attacked and bitten by the same kind......

and being acquired by the forest wind.

A scaly, hard layer that is cumbersome to cut with a knife.

This thing even against bullets,

All have some degree of defense.

I hope the zombies won't continue to stack armor,

Otherwise, you will have to find a weapon to take advantage of in the future.

The pituitary gland and adrenal glands of the seven zombies,

They are taken off sequentially.

Put it in a bag, about a pound in weight.

The kitchen knife in Lin Feng's hand was also folded,

Scrap directly.

Then, he moved the corpse upstairs, threw the corpse as far away as possible to avoid the smell of decay, and at the same time fed the zombies in the community something to eat.

Lin Feng didn't want them all to starve to death,

I don't want to give birth to a first-level zombie too early.

Back upstairs with the materials,

You can smell the aroma of stir-fried food in the corridor.

When she opened the door and entered bedroom 601, Xia Yuting hadn't woken up yet.

Lin Feng picked up the power bank, and the remaining power was 60%,

The air conditioner plus the electric fan does not consume much electricity.

Two kilowatt-hours of electricity in one night is less than a point.

However, I still took advantage of the big sun and charged first.

Step out of the bedroom with the power bank and onto the balcony to set up the solar charging panels and connect the car refrigerator at the same time.

Find the rest of the medical alcohol and saline,

Directly make three booster immunizers,

and three renin extracts.

Other materials are left in the refrigerator for insurance.

Xia Yuting's blood stains are only enough to make an immunizer.

The other two are Lin Feng's own.

Counting the remaining one booster, there are three in total.

Lin Feng planned to try the effect again.

The big meal I ate yesterday has not yet been digested,

Enough for him to reinforce.

If it's not enough, go next door and eat more.

After an injection,

This time, except for some dull pain,

Didn't feel anything else.

Lin Feng frowned slightly.

Is it already the limit to strengthen it three times?

Although its own strength is still slowly growing,

But it is difficult to make a qualitative leap.

Sure enough, there is still a big gap in the effect of immune-boosting agents compared with real evolutionary agents.

Strengthening can only make the physique reach its own limit.

This point in the last injection,

Lin Feng was faintly aware of it.

If you want to become stronger, you have to inject evolutionary agents,

Start a leap in the level of life.

Like 0.999 ......, infinitely close to 1,

But they will never reach 1.

A tadpole that grows four legs,

If you don't cut off your tail, you'll never be a frog.

This is Lin Feng's current state.

He can feel the limits of his physique,

On top of that,

is an insurmountable chasm,

That's an evolutionary yoke from genes.

If you want to break through it, you have to collect new materials.

Completed the synthesis of the first level of the Evolution Agent.

Lin Feng took a deep breath and put the rest of the immune booster, along with the renin extract, into the refrigerator.

When I was just about to call Xia Yuting for dinner,

She had woken up and opened the bedroom door.

Xia Yuting's complexion is good, she worked hard last night, and it didn't affect much.

Her face became rosy and fresh,

It was like being several years younger overnight.

bare long legs, walking out on tiptoe,

With a hint of the playful appearance of a young girl.

It's just that the footsteps are a little twisted,

It will take a little time to get used to being a woman.

However, when she stuck to Lin Feng's body, the first thing she said was

revealed her true nature:

"Lin Feng, take me to kill zombies when you have time!"

Xia Yuting is still the same Xia Yuting,

Her cute girlish heart is only in front of Lin Feng.

And in the bones,

It's still that crazy woman.

Lin Feng nodded,

He likes women who take the initiative.
