From the first moment of Pain's invasion, those dark Black Receiver with Rinnegan Chakra became Konoha Ninja's nightmare.
At first, three Jonin from Police Force tried to attack Human Path at close range. As soon as they rushed forward, Black Receiver was pierced in the shoulder and abdomen by the opponent's backhand. Originally Jonin, who was not weak in strength, lost control of Chakra in an instant, and fell limply to the ground. Hand Seals didn't even have the strength to do so, and could only let the other party take away his soul without even a chance to resist.
Later, when Kakashi was being pulled by Banshō Ten'in, he was almost pierced through the chest by Black Receiver. Even if Black Receiver just brushed his arm, the Chakra in the meridians were confused for a while, almost ruining the subsequent counterattack. Opportunity. Even Naruto with Sage Mode turned on was unable to smoothly condense Senjutsu Chakra when it was pinned to the ground by Black Receiver. He could only watch himself being controlled, which ultimately triggered Nine-Tails's rampage.
Those Black Receiver seem to carry a strange curse. After being pierced into the body, they will continuously release special Chakra signals, disrupting the flow of Chakra in the meridians, and even directly invading the nervous system, making the body not listen to the brain's instructions. What makes Konoha's medical ninjas even more desperate is that this kind of Black Receiver cannot be processed routinely.
"It can't be pulled out! It can't be pulled out at all!" In the temporary first aid shed, a young medical ninja was sweating profusely. He looked at the Black Receiver stuck in the injured leg, and his hands kept shaking. He tried to wrap Black Receiver 0 with Chakra., I wanted to pull it out, but as soon as my fingertips touched Black Receiver, my Chakra was disturbed by a strange force, instantly confused, my fingertips became numb, and I couldn't even condense Chakra.
The ninja lying on the ground was sweating all over in pain, gritting his teeth and roaring, "Don't touch it! It hurts like hell if you touch it! Chakra jumps around like fire!"
Shizune next to her rushed over and tried to carefully wrap Black Receiver with her Chakra, trying to eliminate the interference signal inside, but as soon as her Yang Release Chakra got close, she was hit by the Rinnegan emitted from Black Receiver. The Chakra was washed away. She could clearly feel that the Chakra frequency in this Black Receiver was extremely special, as if it was specially designed for the ninja's Chakra circulation system. It was extremely disruptive and the conventional Medical Ninjutsu could not cope with it at all.
What's even more troublesome is that after Black Receiver is pierced into the body, it will quickly adhere to the meridians and nervous tissue. If it is forcibly removed, it will directly destroy the entire meridians and nervous system, turning the injured person into a complete disabled person. However, if the Black Receiver is not removed, the interference signals continuously released will continue to destroy the Chakra circulation and body functions of the injured person, eventually leading to systemic organ failure, and he can only die slowly in pain.
In just a few hours, more than a hundred ninjas were injured by Black Receiver in Konoha. Nearly 30% of them had died due to Chakra's complete disorder and organ failure. The remaining people were also struggling on the verge of death. The medical ninjas were helpless and could only watch as their vital signs disappeared little by little.
And these Konoha medical systems were helpless. Black Receiver, Rinto had already obtained the samples before Pain invaded. Back then Jiraiya died in the battle, and Sage Fukasaku brought back Animal Path's corpse and Black Receiver fragments of Pain. Shikamaru helped him apply for a complete sample. He had already done preliminary work Detection and dismantling. It's just that the previous sample only had a small fragment, and the data that could be obtained was limited. But now, the entire Konoha battlefield is full of scenes of Pain using Black Receiver. From Black Receiver The entire process of 's throwing, piercing the human body, and Chakra's interference, to Black Receiver's mechanism of action in the living body and its blocking effect on the nervous system, all details were completely captured and recorded by his sensory nodes.
In the laboratory, Rinto had just finished filing the space model of Chibaku Tensei, then turned and walked into the sterile operating room. The fragments of Black Receiver he had saved before were placed in a high-precision testing instrument, and the one next to it was On the light screen, the data collected by the sensing nodes on the effects of Black Receiver in different ninjas are being played simultaneously, including the dynamic changes in the entire process of Black Receiver penetration, Chakra release, and nerve blockade.
He has previously determined through preliminary testing that Black Receiver is a special substance created out of thin air using Yin-Yang Release, which has both stable physical properties and extremely strong Chakra conductive properties. But as for the underlying mechanism of its Chakra interference, there were only theoretical conjectures before, without complete live measured data to support it. But now, hundreds of real cases on the battlefield have just provided him with the most comprehensive and extreme experimental data.
The sensory data clearly restores the entire process of Black Receiver: After Black Receiver is pierced into the human body, it will instantly release a high-frequency, special frequency band Chakra wave. This wave will directly disrupt the Chakra resonance in the ninja's meridians, causing the originally orderly circulation of Chakra to change. It becomes chaotic and out of control, and cannot condense Hand Seals at all. At the same time, this kind of fluctuation will spread rapidly along the nervous system, blocking the transmission of nerve electrical signals from the brain to the body, causing the stabbed ninja to become paralyzed and lose control of the body. This is why even Jonin will instantly lose combat effectiveness after being stabbed by Black Receiver.
What's more interesting is that by comparing the case data of different ninjas, Rinto found that the interference effect of Black Receiver has no direct positive correlation with the target's own Chakra magnitude and Chakra control accuracy. Even Tsunade's level of If a strong Kage Level person is stabbed by Black Receiver, the Chakra cycle will also be significantly interfered with, but the duration and impact of the interference are lighter than that of ordinary ninjas. Because its interference is directly aimed at the transmission link and nerve signal conduction of Chakra, rather than simply suppressing it at the Chakra level.
"So that's it. The essence is the suppression and interference of the Chakra frequency." Rinto looked at the spectrum diagram on the light screen with a clear look in his eyes, "Black Receiver itself is a fixed signal transmitter. The emitter continuously releases interference waves that are contrary to the frequency of the ninja's regular Chakra, directly disrupting the resonance of the Chakra, and at the same time blocking the ion channels of the nerve cell membrane, which is equivalent to abolishing the core ability of the ninja from the hardware level."
He even disassembled the other two core functions of Black Receiver through cross-validation of multiple sets of data: remote Chakra transmission and positioning. Rinnegan in Black Receiver Chakra will form a continuous encrypted link with the distant Nagato, which can not only transmit the Chakra and instructions for controlling the puppet corpse, but also reversely locate the location of Black Receiver, and even share the vision and perception information around the person being stabbed through Black Receiver.
After figuring out the underlying mechanism, Rinto immediately launched targeted verification experiments.
He took out different types of cell samples that he had previously saved, including ninja's somatic cells, meridian endothelial cells, nerve cells, and his own somatic cells, and placed them in numbered culture dishes. He then cut out a very small sample of Black Receiver and placed it in a culture environment. He used a high-power Chakra microscope throughout the process to track the impact of Black Receiver's interference waves on the cells and record every subtle change.
He accurately recorded the impact of interference waves on cell Chakra receptors, the blocking effect on cell membrane ion channels, and the inhibitory mechanism on nerve cell signal transmission, paying no attention to every detail. He even specially designed a control experiment to test the resistance effect of Chakra with different Chakra properties and different Yin-Yang Release ratios against this interference wave.
The results of the experiment came out quickly: his own cells, due to their long-term fusion with Senjutsu Chakra and his absolutely precise control of his own Chakra frequency, could easily block the interference wave of Black Receiver. Only To adjust its own Chakra resonant frequency, you can completely ignore the Chakra interference of Black Receiver, and even reversely eliminate the Rinnegan in Black Receiver Chakra.
Based on this discovery, he casually designed a set of Chakra frequency anchoring configurations. As long as this configuration is carved into the core node of the Chakra cycle, he can be completely immune to the interference of Black Receiver. Interference can even block Black Receiver's remote positioning and signal transmission. Of course, he just made this configuration and encrypted it in his own database, with no intention of sharing it with Konoha.
For him, it has nothing to do with him whether Konoha's ninja will be restrained by Black Receiver or whether he will die as a result. He studies Black Receiver's interference mechanism just to improve his research on Chakra frequency, signal transmission, and Yin-Yang Release creations, and just to satisfy his desire to explore the rules of the world.
He even optimized his previously designed Chakra remote control model based on Black Receiver's ultra-long-distance Chakra transmission mechanism. Black Receiver's low-loss, ultra-long-distance The signal transmission logic is much more stable than Shinobi World's existing communication frogs and symbols. Even if it is hundreds of kilometers away, Chakra signals can be accurately transmitted. This mechanism can help him perfect the subsequent multi-node remote experimental layout.
On the battlefield outside, Six Paths of Pain is still relying on Black Receiver, constantly clearing out the remaining Konoha Ninja. The ninja stabbed by Black Receiver, either losing combat effectiveness on the spot and being killed, or being carried back to the first aid shed, waiting for death in pain and despair. The medical ninjas were still helpless to deal with these wounded people, and could only use painkillers to barely relieve their pain, and could do nothing.
In the laboratory, Rinto has completed the full-dimensional disassembly experiment of Black Receiver, and compiled Black Receiver's material composition, Chakra interference mechanism, signal transmission logic, and nerve blocking principle into a complete research report, which was filed in the encrypted dossier of Rinnegan's research.
He didn't step out of the laboratory during the whole process, and he didn't even get a new Black Receiver sample. He only relied on actual measurement data on the battlefield, plus the remaining fragments, to completely figure out all the secrets of this weapon that made the entire Konoha fearful.
