They found that the subject's blood briefly boosted the person's physical strength, but after about three to four weeks, the person mutated into an unconscious zombie.

What's even more terrifying is that the virus is spreading rapidly in the city, and they are powerless to stop it.

After watching the video, they didn't find any clues to leave.

In addition to Zhen, he took a closer look at all the monitors and found that among so many monitors, there was one monitor that was particularly special.

It wasn't just the seven of them, they were around a woman who was lying on the autopsy table giving birth.

The woman's cry that Xia Ling'er heard before was this woman's voice.

And that child was the first successful subject of the "moonlight" experiment.

In the lower right corner of the screen, the date of this day is shown, the day on which the first successful test subject was born.

"This should be the password, but where can I enter it?" Xia Ling'er asked suspiciously.

The door couldn't be opened from the inside, there must have been some other place where the password could be entered, and several people quickly found it in the room.

In the end, Lin Guiyao found a combination lock behind the large monitoring screen that played the birth process, and after entering the date of the child's birth, he only heard a "click", and a door was opened on the wall not far away.

The door and the walls were white, and when they closed it, the door was perfectly hidden in the wall, and if they hadn't found the code, they probably wouldn't have even been able to find the door.

Entering the door, there is a narrow children's room, which is very oppressive inside.

A small bed was in the corner, with worn-out toys scattered on the floor, and several pictures on the wall, from birth until the child was seven years old.

However, it is not a life photo, but a photo recorded for the purpose of experimentation.

In addition to Zhen coming forward, since he was a child, the more he looked behind, the more he felt that this face was a little familiar, but he couldn't remember who it was for a while.

There is also a door inside the room. Although the rooms are locked from the outside, the rooms inside are connected, including the rooms on the first floor.

They walked through the entire room of the small white building, most of which were laboratories, as well as the remains left over from live experiments, and some rooms were for scientific researchers.

Inside, they found a diary, presumably from the researcher's wife, detailing the progress of the experiment and the outbreak of the zombie virus.

July 1

Seven years have passed, and after our observations, the test subject is very healthy, and the body indicators are much stronger than the average seven-year-old child, and the experiment should be successful.

Although so many lives have been sacrificed, it is all worth it for the sake of human evolution.

July 2nd

In the second stage of the experiment, we conducted experiments with the blood of the test subjects, and found that by injecting blood, the body's functions can be rapidly strengthened.

July 30th

We failed, and although injecting blood can make people evolve in a short period of time, they will soon become zombies.

The government had come to drain the blood of the test subjects, hoping they hadn't used it yet.

August 3rd

The army surrounded the lab, and a high-ranking person injected blood and turned into a zombie, and the boss told us to come up with a cure within a month, or else he would kill us all

August 15th

I overheard the conversation between my husband and the upper echelons, and it turned out that the so-called human evolution was all a lie, and they only intended to let those upper echelons evolve so that they could better rule over humanity.

He's lying to me!

August 19th

I've heard that the zombie virus is spreading, how could it be......

August 22nd

It turns out that people's hearts can be so dirty, in order to seize power, they can use the zombie virus on their opponents, in their eyes, what is human life!

August 25th

The virus has spread to the city, and we have to speed up the antidote.

September 2nd

We still haven't figured out the antidote, we're dying, it's retribution, retribution.

……

The diary ended up on September 2nd, and although there is no follow-up record, it can probably be deduced.

Because they couldn't find an antidote, the upper echelons were furious and locked them up, that is, the monitoring of the above picture, and then they were probably either fed the zombie virus or killed.

To say that they are pitiful, in fact, they are not innocent people, how many people were killed in the live experiment, and the zombie virus was also researched later.

Even if this is not the root cause of the city's demise, the mistakes they made are unforgivable.

When they came out of the last room, the sky was already slightly white, and a little sunlight shone into the small white building through the cracks in the ruins, and they saw a figure standing outside the small white building, with his back to them.

It's like I'm waiting for them.

Several people immediately became vigilant, except for Zhen squinting his eyes, he always felt that this back was very familiar.

The man turned around, and when they saw his face clearly, everyone was a little surprised.

It's the "hero"! It turned out that he was not in the small white building, no wonder they couldn't find him.

Looking at that familiar face, a picture flashed through Except Zhen's mind.

She finally knew why she felt so familiar when she saw that little boy's face, because that little boy was a "hero"!

He's the test subject!

"You all already know the secrets of this city." He smiled faintly, as if he knew it.

His eyes were clear, completely different from those unconscious zombies outside.

"You're the test subject?" Although he had confirmed this in his heart, he still asked out loud.

He didn't deny it and nodded, "That's right, I'm the root of the zombie virus." ”

Then he smiled bitterly and said in a low voice, "If only I hadn't been born." ”

But even if it weren't him, other test subjects would have been born.

Experiments will continue on and on, and countless innocent people will be brutally subjected to human experiments until a successful test subject is created.

"How the hell did the virus spread?" Lin Guiyao suddenly asked.

Xia Ling'er was a little puzzled, "Isn't it spread by those upper echelons in order to shackle political opponents?" ”

Lin Guiyao shook his head, "At most, it's just the early stage, and it won't turn the entire city into zombies, and there must be someone among them who is fueling the trouble." ”

The "hero" was shocked by his carefulness and nodded, "That's right, someone is indeed fueling the trouble, and that person is Lu Jin." ”

After turning around in Xiaobailou for such a circle, they have basically recognized all the scientific researchers, and they also know who this Lu Jin is.

It's the guy who kept laughing on the surveillance before.

"He was the one who spread the virus." "Hero" said viciously.
