The waveform graph on this report is very dazzling, like a fish bone stuck in the throat.
Chiyo Saori's fingers pressed firmly on the soaring red line, and his knuckles turned slightly white from the exertion.
That's an almost negligible micro-movement.
At the moment of high-speed running, the human body's balance mechanism will instinctively correct the center of gravity by raising the lower jaw, followed by an upward shift of the line of sight.
Although it's only a tenth of a second.
But in Uchiha Xuan's eyes, this tenth of a second of looking up means that the spine has not completely bent.
As long as you can still raise your head, you are looking for a reference in the sky. This is a sign that the creature wants to stand, and it is an unforgivable "arrogance".
If this physiological instinct is not cut off from the root, these "new humans" who have spent huge resources to cultivate will sooner or later try to stand up and look at the outside world at a critical moment.
Xuan did not pick up the report, but casually picked up the cup of tea that had already cooled down on the console and took a sip.
The bitter taste spread in his mouth, sobering up his mind which was a little swollen by the pile of data.
Since brainwashing at the software level will be countered by biological instinct, then just change the hardware directly.
He drew the system interface in the void.
Up there, the gene chain analyzed by Myriad Phenomena Devouring System is slowly turning like a spiral staircase.
Xuan's eyes were as cold as looking at a pile of dead meat, and his fingers quickly modified a key base pair that represented the development of the spine.
Gene template overwriting and activation.
He used certain chakra qualities of his as a viral patch and forcibly injected it into the bodies of all individuals connected to the cultivation network.
This is not a gift of strength, but a violent demolition that occurs at the cellular level.
Modifying the parameters is very simple: compress the activity space of the third and fourth cervical vertebrae, solidify the curvature of the lumbar vertebrae, and forcibly twist the stress-bearing structure originally used for upright walking into an arch bridge shape suitable for all fours on the ground.
The next second, the screams even penetrated the thick soundproof glass.
That was not a few people screaming, but the simultaneous wailing of 300 individuals undergoing adaptive training in the entire base.
That voice didn't sound like a human being, but more like the roar of some kind of beast before it died.
In the surveillance footage, the running subjects collapsed to the ground as if their bones had been ripped out.
Their bodies were twitching violently, and the bones under their skin made a heart-wrenching "click" sound, as if an invisible hand was forcibly bending their spines into another shape.
Some people fainted from the pain, foaming at the mouth, and their bodies were still spasming unconsciously.
Chiyo looked at the soaring heart rate reading and frowned even more tightly. She glanced at Xuan who was indifferent beside her, moved her lips, and finally said nothing. She just silently increased the power of the life support system to prevent these precious experimental products from dying at once.
Eighty-nine people went into shock on the spot.
The remaining people got up again after ten minutes - just got up.
The individual numbered D-13 was originally the strongest in this batch.
He staggered and tried to stand up straight, but as soon as he was halfway up, there was a dull popping sound from his lumbar spine.
He folded forward suddenly and hit his face heavily on the metal floor. The crisp sound of the broken nose bone was particularly clear in the dead silence of the training ground.
This is not an isolated case.
The subsequent actual combat test was a disaster.
In order to avoid a sweeping wind blade, another subject subconsciously wanted to jump up.
This is the fighting instinct engraved in human genes, jumping, staying in the air, and avoiding.
However, the moment he exerted his strength, the redefined spine betrayed him.
His body froze in mid-air, and the bones in his waist were unable to withstand this reverse stretching force and were instantly dislocated.
The whole person fell to the ground like a broken rag doll and could no longer move.
Follow-up medical scans showed that his third lumbar vertebrae had suffered permanent structural deformation, which was irreversible damage.
This scene was like a basin of ice water, extinguishing everyone's remaining thoughts of "standing".
They finally understood that the price of trying to fight against this body's new rules would be to become a useless person.
As a result, the remaining survivors began to behave.
Facing the same wind blade, they no longer tried to jump, but instead lowered their bodies lower, almost sliding against the ground.
Chiyo pushed up his glasses, with a hint of worry in his tone. "Although this change in physiological structure eliminates the possibility of rebellion, it also abolishes their three-dimensional mobility. If they do not install an exoskeleton support device, their tactical value will be greatly reduced."
"Exoskeleton?" Xuan sneered and closed the proposal window.
He doesn't need an almighty warrior, he needs a pure hound.
Hounds don't need to jump up and bite people's throats. They just need to sneak in the grass and bite off the ankles of their prey.
Just change the battlefield into an environment suitable for them.
An order was issued, and the originally empty and tall training ground began to deform.
All lookouts and high walls were demolished and replaced by intricate low bunkers and maze-like ravines.
The ceiling has been lowered to the limit, making the cramped space suffocating, but it has become a paradise for these "crawlers".
Only seven days have passed.
New data is out.
Although the average movement speed dropped by nearly half, the success rate of raids in such low terrain increased by 60%.
They are like some kind of shadow creatures that spawned from the sewers. They are extremely low in stature and difficult to be targeted by conventional sight, and their attack angles are even more tricky and weird.
It's late at night.
Xuan stood in the control room with his hands behind his hands, watching the scene on the screen.
That's the sleeping cabin in Area C.
All the "new humans" have fallen asleep, but no one is lying down.
They curled up into a ball like fetuses still in the mother's womb, with their backs arched and their foreheads firmly pressed against their knees.
Even in the most relaxed sleep, their bodies have forgotten how to stretch, as if this humiliating posture is the only source of security.
This uniform distortion reveals a kind of cult-like piety.
At this time, the puppet responsible for cleaning up the ruins of Naka River Shrine sent back a video.
In the mud at the bottom, a fragment of an ancient stone tablet was dug out.
The handwriting on it is blurry, but under the infrared scan, half of a prophetic sentence can still be discerned. "... God comes into the world, and all bones will bear his knees."
Xuan stared at the line of words for two seconds, without any emotion in his eyes.
The next moment, a black flame ignited out of thin air in the ruins.
That was the black flame of Amaterasu, swallowing up everything domineeringly.
The stone tablet and the so-called prophecy turned into nothingness in an instant.
He doesn't need any ancient prophecies to endorse his actions, let alone such dead things to define his "rightness".
After doing all this, Xuan turned and left, leaving only Chiyo behind.
Chiyo, who had been silently sorting out data, stopped with his finger on an audio file that had just been archived by the system.
It was a piece of background noise during the renovation of the training ground. It should have been deleted as useless data, but at the end of the waveform, an extremely unnatural frequency jitter appeared.
