The atmosphere in Konoha Medical Division's most advanced testing laboratory was extremely tense.
When Shizune rushed over with the arm fragment, Medical Division's top medical ninjas and senior researchers in the research class were already in place, and all testing equipment was turned on and ready.
Everyone knows very well that this fragment contains the core secret of the strange and undead enemy, and it is also related to whether Konoha can deal with such a terrifying enemy in the future.
"Open the sterile isolation cabin, put the sample in, and first do basic vital signs testing, cell activity analysis, and Chakra spectrum analysis." Shizune immediately issued the order with a serious tone.
Two researchers wearing sterile suits carefully took the seal scroll, opened it in the isolation cabin, took out the arm fragment, and placed it on the testing table.
The moment the fragments were taken out, everyone in the laboratory took a deep breath, with expressions of disbelief on their faces.
A full day has passed since the patrol was attacked. Logically speaking, this severed arm should have lost its activity long ago and started to rot and necrosis. But the arm in front of me not only showed no sign of necrosis, but the fractured wound was actually still slowly squirming in an attempt to regenerate the missing tissue. Even if there was only one arm, it still showed a terrifying regenerative ability.
"Oh my god... I've been out of the body for so long, and I'm still regenerating?" A researcher couldn't help but exclaimed, "This is completely unreasonable! Without the supply of Chakra, and without the support of the origin of life, how can the tissues outside the body continue to regenerate?"
"Don't be stunned, start testing immediately!" Shizune calmed down and urged quickly.
The researchers immediately came to their senses, activated all the testing equipment, and began to conduct comprehensive testing on the fragments. The high-precision Chakra spectrum analyzer, cell activity analyzer, and microstructure microscope were all aimed at the sample, and groups of data were continuously refreshed on the light screen.
But as the test progressed, everyone's faces became more and more solemn, and the shock and confusion in their eyes became deeper and deeper. Because the test results completely overturned their understanding of the human body, Chakra, and the rules of life.
"The cell viability test results are out... it's too outrageous." The researcher in charge of the cell test, his voice trembling, "The cells in the sample are extremely active, dividing and regenerating hundreds of times faster than normal human cells, and there are no signs of apoptosis at all. What's even weirder is that these cells are not human somatic cells at all. There are two completely different gene sequences mixed in them, and there is also a foreign, forcibly bound Chakra imprint."
"There is also a problem with the spectrum analysis of Chakra." Another researcher followed up and reported, "Chakra in the sample is divided into three parts: one part belongs to the dead Sunagakure The Chakra mark of the Magnet Release ninja carries the Kekkei Genkai characteristics of Magnet Release; part of it is a cold, foreign Chakra used for restraint and control, which does not belong to the dead at all; and the other part is a steady stream of life energy that maintains infinite regeneration, with a completely unknown source, and does not come from the cells themselves at all."
"There is something even stranger." The researcher responsible for the microstructure examination said with a pale face, "We have detected extremely weak soul fluctuations and traces of binding in the cell nuclei. It is as if... there is a ray of soul fragments that are forcibly locked in each cell. This is also the reason why it can regenerate outside the body? But how is this possible? How can the soul be split into this and still locked in the cells?"
Groups of weird test data were placed in front of everyone. They had been engaged in medical and Ninjutsu research for a lifetime, and they had never seen such a phenomenon that went against common sense.
The isolated tissue can regenerate infinitely, the mixed gene sequence, the traces of the soul that are split and locked in the cells, the three completely different Chakra intertwined, and the endless life energy of unknown origin. All of this is beyond their cognitive scope. Let alone finding a way to crack it, they can't understand even the most basic regeneration mechanism.
Shizune looked at the test data on the light screen, her brows knitted into knots. She had studied Medical Ninjutsu with Tsunade for more than ten years, and had seen countless difficult and complicated diseases and weird secret techniques, but facing this fragment, she couldn't figure it out at all. She even tried to use Yang Release Chakra to interfere with the regeneration of the sample, but as soon as her Chakra touched the sample, it was bounced away by the cold restraint Chakra, unable to affect the regeneration of the cells at all.
A few hours passed, and all the tests that could be done were done, but apart from figuring out the surface characteristics of the sample, they knew nothing about the core mechanism behind it. Not to mention cracking the regeneration ability, they couldn't even explain what this thing was.
"How's it going? Are there any results?" Tsunade, Shikamaru, Kakashi and others hurriedly Earth Flow entered the laboratory and asked immediately as soon as they entered the door.
Shizune shook his head with a wry smile and handed over the test report, his tone full of weakness. "Lady Tsunade, we have done all the tests we can, but we can't understand its mechanism at all. This thing is too weird, completely contrary to our known medical and Ninjutsu common sense. We can't even figure out its regeneration principle and soul binding method."
Tsunade took the test report and flipped through it quickly, her expression getting darker and darker. Every set of data in the report was full of weirdness. Even Shinobi World, a top medical ninja like her, could not understand the logic at all. She could feel the traces of soul restraint in the sample and see the terrifying cell regeneration ability, but she could not understand how all of this was achieved.
Kakashi also came over to read the report. Sharingan shrank slightly, his eyes full of solemnity. He had copied thousands of Ninjutsu and had seen countless secret techniques, but he had never seen anything like this.
"This is simply not something that conventional secret techniques can do." Shikamaru looked at the report, his mind racing, but even he couldn't find any breakthrough, "Forcibly binding the soul of the deceased to Kekkei Genkai in a strange body can achieve infinite regeneration. This has gone beyond the scope of conventional Ninjutsu and touches the soul and the rules of life and death."
There was deathly silence in the laboratory, everyone was silent, and their hearts were full of powerlessness. They could not even understand the principle of this fragment, let alone find a way to deal with it. If such an enemy appeared on a large scale, Konoha would have no ability to resist.
After being silent for a long time, Tsunade raised her head, a trace of determination flashed in her eyes. She looked at everyone and said in a deep voice, "Now, only one person can understand what this thing is."
Everyone instantly understood what she meant - Mr. Rinto.
In the entire Shinobi World, the only one who can see through the rules behind this strange phenomenon and dismantle the core mechanism is Mr. Rinto, who lives in seclusion and has understood even the rules of life and death and the essence of the soul.
But then, someone showed a hesitant look.
"But...Mr. Rinto hates being disturbed. Every time we went to him before, we always went with clear research value and data. Although the sample this time is weird, we have no idea how it works, and we don't know if it can arouse his interest. Moreover, this thing involves unknown forbidden arts and soul binding. Are there any risks?"
"There are definitely risks, but we can't control them so much now." Tsunade gritted his teeth, "The enemy behind this thing has threatened the safety of Konoha. We must understand its nature and find a way to crack it. Moreover, this kind of sample involving forced soul binding and unconventional regeneration mechanism should be of research value to Mr. Rinto."
Shikamaru also nodded, with a firm tone. "That's right. Mr. Rinto has done in-depth research on soul rules and cell regeneration before. This kind of sample has never been touched by him before. The forced soul binding and immortal regeneration mechanism involved in it should be of great value to his research. There is a high probability that he will be willing to study it."
"Okay." Tsunade immediately made up his mind and picked up the seal scroll containing the sample, "I will take it there myself and go now."
