The precursor of Shinra Tensei is the Chakra distortion over the entire Konoha.
At this time, three hours had passed since Pain invaded. Konoha, which was originally well-organized, had already been swept away by the flames of war. The giant psychic beast channeled by Animal Path ran rampant on the street, and Asura Path's missile exploded One building after another collapsed, Preta Path expressionlessly devoured the Ninjutsu that the ninjas tried their best to release, while Human Path shuttled through the houses, leaving only corpses that had their souls taken away and were still warm wherever their cold fingertips passed.
On the top floor of the Hokage building, Tsunade stood by the broken window. The Yin Seal on her forehead had already been fully unfolded, and countless Katsuyu spread from under her feet. Driving along, along the streets and ruins, towards every place with vital signs. Her face became paler and paler, and she was frantically consuming the stored Chakra every second, but the news coming back from the front line became more and more desperate every time.
"Lady Tsunade! The western defense line has been breached by psychic beasts! The casualties are too great, we can hardly withstand it anymore!"
"Lady Tsunade! The hospital has been affected, more than half of the medical ninjas were killed or injured, and all the medicines and equipment were buried!"
"Lady Tsunade, Deva Path Pain left the battlefield and headed towards the sky in the center of the village!"
This last piece of news made Tsunade's heart suddenly sink. In the information that Jiraiya desperately sent back, there was very little description of Deva Path's abilities. It was only known that he could control a strange repulsion and gravity, and it was almost impossible to attack and defend at close range. But the opponent suddenly lifted into the air, not to avoid attacks, but to release some kind of large-scale terrifying technique.
"Notify everyone immediately! Hide in the underground shelter! Hurry!" Tsunade roared into the communicator, and at the same time, he tried his best to activate Katsuyu, asking all clones to protect the civilians and ninjas within reach at all costs. But it was already too late.
Deva Path Pain is suspended hundreds of meters above the center of Konoha. The orange-red Rinnegan is indifferently overlooking the village below. The Chakra around it is gathering crazily at a devastating magnitude. Even the surrounding air is distorted. The invisible weight is like a tsunami, making people on the ground breathless.
There was no emotion in his voice, but it penetrated the gunfire and screams, and spread clearly to every corner of Konoha: "Let the world feel the pain. Shinra Tensei."
The next second, a spherical repulsive shock wave visible to the naked eye exploded in all directions with him as the center.
The first thing to be crushed was the high-altitude clouds, followed closely by the Konoha tallest Hokage building. The reinforced concrete was torn to pieces like pieces of paper in the face of the extreme repulsion. The hard rock instantly turned into powder and burned. The burning flames were extinguished instantly, and the hundred-meter-high psychic beast was crushed into a pulp by the shock wave without even letting out a scream. Streets, houses, entrances to shelters, and even the soil several meters underground were all lifted, crushed, and flattened layer by layer by this indiscriminate force.
The screams, the roar of the collapse of the building, and the crisp sound of the Ninjutsu barrier breaking were all drowned in the terrifying roar swept by the repulsion. Tsunade tried his best to Chakra, let Katsuyu wraps up everyone it can cover, but even if she turns on Strength of a Hundred Technique, she can clearly feel that countless vital signs attached to Katsuyu are extinguishing at an alarming speed.
In just ten seconds, the entire Konoha turned from a prosperous ninja village into a huge circular ruin. Except for the northwest corner where Rinto's laboratory is located, and several core points where secondary barriers were laid out in advance, there was almost no complete building in the entire village. The ground was cut off several meters, and as far as the eye could see, there were all rubble, rubble, as well as corpses and dying wounded buried under the ruins.
The smoke and dust fell slowly, and Deva Path Pain slowly landed in the center of the ruins. Rinnegan swept across the dead village indifferently without any emotion. What he wanted was not only to destroy Konoha, but also to force out the hidden Nine-Tails Jinchuriki Naruto Uzumaki.
In the northwest corner of the village, in the space mezzanine that was not even shaken by the devastating shock wave, Rinto's laboratory was as quiet as another world.
As early as the moment Deva Path Pain started to gather Chakra, the global sensing light screen placed by Rinto next to the experimental table automatically lit up the warning. He was optimizing Konoha before. When protecting the village's boundary, high-precision sensing and data collection modules were conveniently embedded in the boundary nodes of the entire village - not to help Konoha with early warning, but just to capture first-hand complete actual combat data of Rinnegan's technique.
He put down the Black Receiver sample he was dismantling in his hand and walked slowly to the light screen. His face showed no emotion at all about the disaster outside. In his eyes, there were only real-time values that kept beating, even with a hint of unnoticeable excitement.
"It's finally here." He whispered, his fingertips quickly moved across the light screen, and he raised the sampling frequency to the highest level. "Don't waste this extreme test of the entire scene."
The entire process of Shinra Tensei from startup to explosion to energy dissipation was completely captured by sensing nodes throughout the village with microsecond accuracy. From the initial convergence rate of Chakra, the configuration changes of Yin-Yang Release, to the repulsive force The moment when the field is generated, the peak intensity of the shock wave, the repulsion attenuation law at different distances, the effect on solid substances, liquids, Chakra barriers, and even Natural Energy, all parameters are meticulously transmitted to the laboratory's storage equipment simultaneously.
Even the vibration transmission of the repulsive force to the ground, the slight distortion of the curvature of space, and the entire process of energy dissipation were completely recorded. Outside was a village-killing disaster that was enough to shake the entire Shinobi World. For Rinto, it was just a rare, extremely large-scale practical demonstration of the rules of gravity.
When the shock wave swept to the area where the laboratory was located, the outer camouflage space mirror perfectly withstood the repulsive impact, and the sensing nodes simultaneously recorded the peak data in the edge area - even at the very edge of the village, the repulsive force was strong enough to crush the conventional Jonin defensive barrier, and his space folding barrier did not even ripple.
Rinto stared at the jumping values on the light screen the whole time. The charcoal pen in his hand was writing quickly on the special slate. Lines of formulas and key parameters were quickly covered on the entire slate. He even completed the preliminary model construction simultaneously during the repulsive force explosion, dismantling the changes in the repulsive force field of Shinra Tensei into a quantifiable and reproducible mathematical model.
When the shock wave completely dissipated and the roar outside fell silent, the light screen was filled with seventeen complete sets of measured data. The energy conversion efficiency from Chakra input to repulsive force output, the range and time threshold of the repulsive force field, and the connection He accurately calculated the cooling interval rules for subsequent releases, and even the loss range of Chakra and the short-term decline of body functions after Deva Path Pain released this Super Shinra Tensei.
"Interesting." Rinto pointed his fingertips on the light screen, enlarging the curve of the peak repulsion force, his eyes full of concentration, "The essence is not Chakra shock wave, it is through Rinnegan's Yin-Yang Release interferes with the basic force field and forcibly creates an omnidirectional spatial repulsion. No wonder the conventional Ninjutsu barrier cannot block it at all. It's not that the energy level is not enough, but that the dimension of action is completely different."
He quickly disassembled the core logic of the technique and pinpointed its flaws. "The energy utilization rate is too low. Nearly 60% of the Chakra is dissipated in the spatial disturbance, and the effective repulsive force that actually acts on the target is less than 40%. This full-range release mode consumes too much Chakra. There must be an extremely long cooling window after release, and it may even temporarily weaken the control ability of the main body."
If any Konoha ninja discovers this fatal flaw, he will immediately try his best to pass the news to the remaining command and find an opportunity to counterattack. But Rinto has no such idea at all, and does not even have the slightest idea of telling others. In his eyes, these flaws are just imperfections in the technique, which are reference materials for him to study the rules of gravity, and have nothing to do with Konoha's life and death.
He casually archived and encrypted the complete raw data, then picked up a charcoal pen and began to optimize his space folding defense system based on the repulsion field data he had just collected. The previous defense configuration was mainly aimed at conventional Ninjutsu impacts and explosions. Now with the measured data of Shinra Tensei, he can add a layer of repulsion reverse dissolution module to the barrier, so that even space repulsion impacts of the same magnitude can be perfectly offset.
At the same time, based on the underlying logic of the repulsion field, he deduced the basic model of the homologous gravitational field in reverse, and predicted in advance the reverse spell that Pain would inevitably use, paired with Shinra Tensei.
From the ruins outside the window, there came the faint moans of survivors, the sound of Katsuyu's moving slime, and the roars of ninjas frantically digging through the ruins, but these sounds could not even penetrate the barriers of the folded space. Rinto did not even raise his eyes to look out the window. All his attention fell on the repulsive field data he had just obtained. The charcoal pen in his hand kept moving, and lines of more precise formulas continued to appear on the slate.
He did not step out of the laboratory during the whole process, and did not even open the barrier of space folding. The village outside was destroyed and people died, and it had nothing to do with him. For him, this catastrophe was just a free and rare test of the Rinnegan technique, which provided unprecedented complete data for his research.
