After the blood becomes semi-coagulated, it must be enriched with a large amount of viruses, which is an excellent sample.

Then Shen Feng took out the broken fingers of the zombies in the glass bottle he brought, and cut off pieces of flesh and blood.

He took two more petri dishes, took out the culture solution he brought, and poured it into the petri dish, and put the thrombus and the piece of flesh into the petri dish together.

Immediately afterwards, he took another petri dish, knocked some debris from the broken finger of the stone statue he brought over, and poured it into the petri dish.

After doing all this, Shen Feng leaned against the back of the chair, and the silicon-based frame on his chest began to play a cheerful Mexican song "La Elisa" in a low voice.

Although what he used in the petri dish was the culture solution for making artificial human biological substitutes, which was extremely efficient, it would take a certain amount of time to restore the maximum activity and reproduction of various viruses.

Take a break.

The melodious and cheerful music reverberated throughout the virus laboratory, making Shen Feng's mood a lot more cheerful.

I have to say that although this land of Mexico is full of disasters and full of magic realism, its people are absolutely optimistic and happy, and absolutely have fun.

This can be seen from the "Day of the Dead" and the country's musical style.

After the song "LaElisa" was played, it was followed by a song "LaPuntada", which told a cheerful story of a licking dog who drank too much and confessed to the goddess.

Shen Feng beat the rhythm of the song, glanced at the nurse who was tied to the bed out of the corner of his eyes, and suddenly stopped suddenly.

The zombie nurse, who was struggling and roaring, became quiet at this time.

The pupils in her eyes were still open, but they became much calmer, as if they had fallen into hibernation.

But looking at her eyes, she was clearly sober.

Shen Feng couldn't help raising his eyebrows.

interesting.

This zombie is obviously influenced by music.

Her brain is absolutely devoid of memory and humanity, there is no doubt about that.

But there is still a little bit of the reaction pattern of the past.

This is like muscle memory, even if it becomes a zombie, it will also be imaged to a certain extent.

The zombie nurse should have liked this song before she died.

At this moment, a song had been sung, and the zombie nurse seemed to be awakened suddenly, and began to struggle and howl frantically again, as if struggling more violently than before.

Shen Feng couldn't help but sigh.

Is this the occasional flash of a little memory fragment?

It's so pitiful...

At the moment, the silicon-based frame that controlled his chest played a song again, this time it was the popular love song "LaLlorona".

Under the influence of the music, the zombie nurse became quiet again, and just stared at the ceiling blankly. She wondered if her already highly mutated brain would flash past her lover when certain passages of this song sounded. Broken image?

Not only the zombie nurses, but even the zombies outside the virus lab who have been scratching the door frantically have become much quieter.

Shen Feng nodded, raised his arm, and started inputting information without the slightest emotion:

"Investigation:

Deeply mutated zombies will be affected by music. Perhaps the sound processing area of ​​the brain still retains some of the former brain tissue structure. It is not yet clear why, and whether there are other specific external stimuli that can cause other changes in zombies.

The specific situation still needs to be tested, but this phenomenon is very worthy of attention. "

After a few songs were played, Shen Feng stood up and stretched, and began to observe the condition of the three samples under the microscope.

The two evil spirit virus samples are exactly the same, and there is no difference. Obviously, the evil spirit virus in this apocalyptic world also does not mutate much, just like the previous world.

This made Shen Feng very relieved.

His vaccine still works well and can save the world's surviving non-immune people.

This is also in line with his initial judgment. After all, he has come into contact with so many zombies, and he can see the difference at a glance.

Then there is the stone statue virus, which has been completely recovered. Under the microscope, it looks like a silent little stone statue, which reminds Shen Feng of the fear of being dominated by the stone statue, and it is a little creepy.

Using a dropper to **** up a drop of the culture solution of the stone statue virus, and drop it into the culture solution of the evil spirit virus, Shen Feng began to observe carefully.

Seeing that the evil spirit virus shaped like a devil and covered with spikes and the silent stone statue virus met, there was no response at first.

Then the evil spirit virus began to gradually move towards the stone statue virus cluster.

Since the single body of the evil spirit virus is several times larger than the stone statue virus, many evil spirit viruses begin to devour the stone statue virus and wrap the other party in it.

At first, the evil spirit virus was still trying to decompose the stone statue virus, but then the stone statue virus began to multiply and split in the body of the evil spirit virus!

In just a while, the stone statue virus has completely absorbed the material of the evil spirit virus, and the more than a dozen stone statue viruses that have been reproduced directly broke the evil spirit virus and completely disintegrated it!

Seeing this scene, Shen Feng couldn't help being a little excited for a moment.

There is a door!

That guy who "one is one for billions, trillions and one trillion" is indeed more powerful than the master of the void!

Soon, most of the evil spirit virus in the petri dish was killed by the stone statue virus, and some petrochemical crystalline particles appeared in the nutrient solution of the petri dish.

Originally, the speed of stone statue disease infection was not so fast, and the speed of petrification on the human body also took a month to gather and then break out.

And now, it seems to be stimulated by the evil spirit virus, the activity of these stone statue viruses has also been greatly enhanced, and the infection time seems to be comparable to the evil spirit virus!

If this kind of stone statue virus appeared in Shen Feng's original world, it is estimated that human beings have been completely extinct.

The evil spirit virus is similar to a kind of catalyst for the stone statue virus.

However, Shen Feng also discovered that the remaining Evil Spirit Viruses no longer devoured the Stone Statue Virus at this time, but started to form a cluster of Evil Spirit Viruses, forming a self-contained area in the culture medium.

Just like the confrontation between the two armies, the stone statue virus began to kill many times, killing a lot of evil spirit viruses on the edge, but it was still unable to completely eliminate the evil spirit virus, because the reproduction speed of the evil spirit virus cluster was too fast, and the stone statue virus Relatively speaking, the speed is much slower, and it is more passive attack after being swallowed.

In the end, the two viruses formed a strange balance in the culture medium. The stone statue virus occupied most of the area, but it was relatively loose. The evil spirit virus was tightly packed, but could not expand, and could only defend an area.

The mutual attack of these two viruses is also very strange.

As if they have their own subconscious and cannot tolerate the emergence of another virus.

Shen Feng then took a syringe, directly extracted the culture solution of the stone statue virus from the petri dish, and came to the nurse zombie tied to the test bed.

The nurse zombie found Shen Feng coming, roared and struggled again, trying in vain to bite Shen Feng.

Shen Feng smacked his lips and said:

"You should have given a lot of injections before. This time it's my turn to give you injections. Be quiet, be quiet, and you'll be fine soon."

The culture solution of the stone statue virus was quickly injected into the body of the nurse zombie.

There was only thick black blood or thrombus blocking the blood vessels left in her blood vessels. Shen Feng doubted whether the stone statue virus could spread to her whole body.

Fortunately, he didn't wait too long.

Just a few minutes later, centered on the area where the syringe was injected, the surface of the nurse zombie's body began to petrify at a speed visible to the naked eye.

The petrified area gradually spread to the whole body, not completely petrified, but about two-thirds of the area was petrified, and the remaining one-third area still maintained the physical activity of zombies, which looked very strange.

Soon, the petrification had reached the neck and head, and most of the face of the nurse zombie was petrified, but it still maintained its original flesh and blood appearance when it reached the forehead and eyes.

It is estimated that the brain part has basically remained as it is, and has not been petrified.

At this time, the zombie nurse looked like a half-human, half-stone monster, which was indescribably weird.

Originally, Shen Feng thought that he could see the zombies completely petrified, but this situation was far beyond his expectations.

Untie the restraint belt and chains on the nurse zombie now, and no longer restrict the other party's movements.

Get up and take two steps.

The nurse zombie struggled to get up and pounce on Shen Feng, but fell directly from the test bed to the ground.

Then he stood up tremblingly, without the ferocity and swiftness that belonged to zombies at the beginning.

It looks like Parkinson's.

Action is extremely slow.

She still had a ferocious look on her face, a low growl came out of her throat, and "pounced" towards Shen Feng, but it took almost five minutes to move a distance of two meters.

Seeing this scene, Shen Feng was overjoyed.

There is a door!

The speed of these zombies infected with the stone statue virus is almost slower than the zombies in the first generation of "Resident Evil", and there is no threat at all.

If all the zombies in this world are this kind of thing, human beings naturally don't have to be afraid, just kill them all slowly.

A beast with the same speed as a snail is not called a beast.

Just stick anything in your eyes or ears and destroy your brain.

However, the stone statue virus is still extremely lethal to surviving humans, causing them to be infected and turned into stone statues.

Still needs improvement.

It is best to cultivate a virus that induces screening mutations and turns it into a special virus that only targets zombies.

More experiments are needed.

Thinking of this, Shen Feng pressed the muzzle of the gun against the zombie nurse's temple, gently pulled the trigger, and ended her life.

After the body was processed, the laboratory was disinfected. After walking out of the isolation room and undergoing disinfection, Shen Feng came to the door of the virus laboratory.

There are still sounds of scratching the door and hitting the door from time to time. Obviously, the zombies have not left just now, and the noise from the virus laboratory from time to time has deeply attracted them.

Shen Feng took a deep breath, gently turned the turntable **** on the door, and the alloy door opened in response.

Then quickly opened the door to a gap that only one person could enter, reached out and grabbed a zombie outside and dragged it inside.

It's just you, the one who scratched the door!

come in for me!
