This familiar object looks like... [A sealed, unknown potion]!
The [Sealed, unknown potion] that dropped when Zhang Chen killed Shang Shan looked exactly like this!
Zhang Chen quickly retrieved the potion from his ring.
He compared it with the potion in the video.
A silver casing, the size of a thermos, with red liquid displayed on a glass surface.
It was identical.
The prompt had also shown this before:
[Awakening Potion, can be used to awaken creatures dormant from the slumber potion!]
At the time, he thought the statement was useless.
Now, it still seemed useless!
However, he now knew what the potion was for!
But... what was inside this Unit 7 hibernation pod?
Judging by its size... the contents shouldn't be particularly large.
It seemed just right for an adult to lie down in.
Could it be a person?
Was Xu Ruina experimenting on living people?
And achieving excellent results?!
But...
According to the video, the zombie horde had already surrounded the laboratory.
If this experimental subject had already been successfully tested,
Why didn't they release it immediately to deal with the zombie horde?
Let alone anything else, with Zhang Chen's current strength, eliminating a zombie horde was well within his capabilities!
Was such an important experimental product still not as strong as Zhang Chen?
Some doubts were cleared up.
Now, more questions arose...
Zhang Chen continued to browse the videos, hoping to find the answers to these questions.
The background of the next video was familiar to Zhang Chen.
Four walls, no windows, and a large glass observation room.
It was clear that Xu Ruina's laboratory had been moved to the air-raid shelter beneath Tianyang University.
Some staff members were busy working behind her.
Due to the limited space of the laboratory, there was no way to isolate an office specifically for Xu Ruina.
Under these circumstances, Xu Ruina spoke much more cautiously, and her tone was more official.
The experimental equipment here is very rudimentary, but we are still conducting experiments on biological energy control!
The bad news is... biological energy has now spread globally. Not only the zombies outside, but many plants and insects have also been affected!
The good news is that the infectivity of the biological energy infection has decreased, and it can only be transmitted through bodily fluids. This has given the survivors a temporary respite!
We have now developed three types of potions that allow the human body to accept biological energy very well!
After injection, physical strength will be greatly enhanced!
We have named them [Basic Physique Potion], [Intermediate Physique Potion], and [Advanced Physique Potion]!
Currently, both the [Basic Physique Potion] and the [Intermediate Physique Potion] have completed clinical trials!
The combat effectiveness of soldiers has been greatly improved, and the balance of war seems to be starting to tilt in humanity's favor...
The [Advanced Physique Potion] is currently unstable, but our research progress is far behind the speed of biological mutation...
The later the research, the more meteorite energy we need!
If I could obtain the core of a meteorite, I might be able to create a god-like existence!
I believe... nuclear bombs can at most destroy the mutated creatures near the meteorite, but they definitely won't destroy the core of the meteorite!
It's a pity that we can't even get out of the air-raid shelter now, let alone go to the meteorite impact site to find the meteorite core!
Some of the subsequent videos had corrupted files and could not be played.
Zhang Chen could only painstakingly watch the playable videos and try to piece together the logic of these videos through his own analysis.
The subsequent content was probably Xu Ruina developing the [Advanced Physique Potion] and constantly conducting experiments.
Later on, she even used survivors for experiments.
Xu Ruina's expression changed from full of hope, to despair, and finally to a state of madness.
She wanted to save all of humanity and allow humans to return to their dominant position at the top of the food chain in the new ecosystem.
But the more anxious she became, the slower her progress.
Coupled with the rudimentary equipment and shortage of supplies in the air-raid shelter laboratory.
The experiments had to be forcibly interrupted in the end.
The last video was intact.
The date was November 7th.
Xu Ruina's eyes were red, as if she hadn't slept for several nights.
Her hair was disheveled, and she hadn't bothered to comb it.
Urgent alarm sounds could be heard from the background of the video again.
The lights in the laboratory were also flickering, as if they might go out at any moment!
Xu Ruina said in a hoarse voice:
Today is probably our doomsday, I hope it won't be the doomsday for all of humanity...
The mutated burrowing worms have broken through the underground concrete defenses and could emerge from anywhere at any time!
The entire world has transformed into a new ecosystem. If humanity doesn't evolve, it truly has no chance of winning!
This is the [Advanced Physique Potion] I have re-formulated, I hope it will be useful!
As Xu Ruina spoke, she slowly injected a tube of blue liquid into her own body.
Afterward, she took out a red string and tied it to her wrist.
I hope my experiment is successful!
This is my last effort to contribute to humanity!
With that, she slowly turned around.
She bowed deeply to the researchers behind her.
Then she said:
Thank you all for your long-term companionship and cooperation!
Our experiments end here!
It has been my honor to work with you all my life!
As Xu Ruina finished speaking.
Suddenly, a purple blood vessel bulged on her arm.
The purple blood vessel extended upwards along her arm, migrating to the carotid artery.
Then half of her face!
Xu Ruina turned her head with difficulty to look at the video.
Then the screen went black.
This was the last video!
A red string?
Could it be... that Wailing One?
Zhang Chen's heart stirred!
He had thought that this Wailing One was a bit strange at the time.
It hadn't attacked him at all.
And it seemed to have followed him later.
Could it be Xu Ruina?
Did she still retain a part of her human consciousness?!
At this moment.
Suddenly, a mournful cry, like a weeping lament, drifted from outside the window.
Wuwuwu... wuwuwu...
Er Pang immediately stood up alertly, shaking his head.
With a vigilant look, he glanced outside the window.
Following Er Pang's gaze, Zhang Chen saw...
Under the moonlight, a long-haired Wailing One, with her hands covering her face.
Standing silently at the edge of the rooftop.
A faded red string tied around her wrist...
