The explosions outside are getting denser and denser. Even if a soundproof barrier is added, you can occasionally feel a very slight ground vibration - that is the shock wave caused by the large-scale Ninjutsu collision and the trampling of the ground by psychic beasts, which is transmitted along the stratum.
The tweezers in Rinto's hand paused, and the action of separating the Chakra mark on the surface of Black Receiver stopped. He put down the tool in his hand, his brows furrowed tighter, and his eyes were filled with impatience.
It's not the fear of war, but the boredom of this kind of endless interference. He optimized the village protection barrier before, just to solve these troubles once and for all, so as to prevent Konoha's war from interrupting his experiments. Now it seems that the other party's destructive power is greater than he expected.
He stood up and walked to the window, his fingertips lightly brushed the glass, and his perception extended along the barrier, instantly sweeping across the entire Konoha. Six Paths. The completely different Chakra ran rampant in the village. One of them carried extremely strong spatial fluctuations, and another one could release a large-scale repulsive shock wave. Even the secondary nodes of the village barrier were shattered.
What worries him even more is that these Chakras all carry the Rinnegan aura that is homologous to Black Receiver. Their ability to control space and Chakra far exceeds that of conventional ninjas.. What he had previously made for the laboratory was a space isolation barrier that could block conventional attacks, perceptions, and space-time raids. However, facing Rinnegan who can control gravity, repulsion, and may even have space capabilities, the existing defense was not absolutely secure enough.
In his laboratory, he has all the research data, files, and samples from all the years since he came to this world, as well as the Mount Myōboku Millennium Senjutsu case that he just got, the Second Hokage forbidden technique manuscript, and the Rinnegan sample that he is currently studying. These things are more important than his life, and there must be no mistakes.
Rinto did not hesitate at all, and immediately stopped studying the Rinnegan sample in his hand, turned around and walked to the central open space of the laboratory, and began to build a new defense system - a multi-layer nested space folding defense configuration.
This is not a minor repair to the original barrier, but a complete reconstruction of the laboratory's defense system from the perspective of space rules. The previous space isolation was to add an invisible "protective shield" to the laboratory to block attacks from the outside world; and the space folding was to separate the laboratory The entire space where it is located is completely hidden in the folded space mezzanine. From the outside, the location of the courtyard is just an ordinary, blown-up open space. All attacks will pass through the folded space and land in the empty space, without touching the main body of the laboratory at all.
He started by building the core formation.
The core of space folding is the reconstruction and deflection of space coordinates, which requires an absolutely stable energy core and an extremely accurate space pattern. Rinto opened the safe at the bottom of the experimental platform and took out the six Chakras with the highest purity that he had kept. crystals - this is the most precious batch among the rewards given to him by Konoha. Each one contains extremely large and purified Chakra, which is enough to support the permanent and stable operation of the space folding configuration.
According to the orientation of the hexagram, he carved six core array eyes on the floor, underground, and ceiling of the laboratory, and embedded six Chakra crystals into them. Each array eye corresponds to the anchor point of a layer of folded space. In order to ensure The array eyes are absolutely stable. He has also embedded a simplified version of the energy self-circulation module in each array eye, which can automatically absorb Natural Energy in the environment to supplement the operation consumption of the array eyes. Even if the energy of the crystal is exhausted, it can maintain operation permanently.
After the core array eye is carved, the next step is the most critical space folding path design.
Rinto does not copy the existing Space-Time Ninjutsu logic of Shinobi World - whether it is the coordinate transmission of Flying Thunder God or the different space distortion of Kamui, they all have their own limitations. It combines Second Hokage The spatial coordinate logic in Flying Thunder God Formula, the spatial isolation configuration I studied before, and even the spatial anchoring rules deduced reversely from the spatial link imprint of Rinnegan Black Receiver, have built a new, multi-layered nested folding model.
He designed a full seven-story folding space.
The outermost layer is the camouflage layer, which perfectly replicates the original spatial environment of the courtyard. Even through Byakugan and Rinnegan's perspective, they can only see an ordinary courtyard and an empty laboratory inside, and cannot sense the deep spatial abnormalities at all. Even if the opponent launches an attack, it will only hit this layer of false spatial mirroring, and cannot even touch the first layer of real defense.
The second to sixth floors are the deflection and dissolution layers. The space on each floor is folded and deflected 90 degrees. Any attack entering these layers will be continuously deflected by the folded space and disperse the energy. Even if it is an explosion shock wave of the Tailed Beast Bomb level, after passing through these five layers of folded space, the energy will be completely dissipated, and not even a ripple will be transmitted to the core layer.
The core seventh floor is the absolutely isolated space where the laboratory body is located. On this floor, he has made a complete closed-loop space, completely cutting off the connection with the conventional space of the outside world. Even if the entire Konoha outside is razed to the ground, the laboratory in this space will not be affected in the slightest. Even the time flow rate has been fine-tuned to ensure that the experimental environment inside is absolutely stable and will not be affected by any interference from the outside world.
In order to prevent Rinnegan's space ability from penetrating, he also added spatial coordinate interference configurations to the barriers of each layer of folded space, which can completely disrupt Space-Time Ninjutsu's coordinate locking. Even the virtualization of Kamui cannot penetrate the folded space barriers, let alone Flying Thunder God's mark transmission. At the same time, he also embedded the anti-perception and anti-Genjutsu configurations previously designed for Anbu. Whether it is mental detection, Chakra perception, or Dōjutsu perspective, they will be silently misled and blocked, and the location of the core space cannot be found at all.
The process of carving array patterns extremely tests precision. The fault tolerance rate of spatial rules is extremely low. Even a micron-level deviation in the array patterns may cause the entire space folding system to collapse, or even cause space turbulence and destroy the entire laboratory. But Rinto's hand is as steady as a precision instrument. The extremely fine Chakra carving knife is condensed on the fingertips. It accurately carves complex patterns on the ground, walls, and even in the air. Every stroke is perfect and there is no mistake.
Midway, there was a rapid knock on the door. It was Anbu's ninja, who came to inform him on Tsunade's order that Akatsuki had invaded and asked him to pay attention to his safety.
Rinto didn't even open the door. He coldly said "I know, don't make any noise" across the barrier. The carving knife in his hand didn't even pause and continued to carve the pattern. Anbu Ninja outside, upon hearing this expulsion order, didn't dare to say another word and immediately turned around and left.
For him, it is meaningless to notify such things. He does not care about the safety of Konoha. What he wants to do is to build his laboratory into an absolutely safe island free from any outside interference.
For two hours, the explosions and shouts of death outside became more and more intense. On several occasions, large-scale shock waves swept near the courtyard and were blocked by the outer barrier, making a dull sound. But in the laboratory, Rinto was always concentrating on carving formation patterns, and even his eyes did not waver. The earth-shaking outside world had nothing to do with him.
When the last formation pattern was carved, Rinto retreated to the center of the laboratory and raised his hand to activate the entire space folding defense system.
With the injection of his Chakra, the six core array eyes lit up with light blue light at the same time. Layers of invisible spatial barriers, with the laboratory as the center, quickly expanded, folded, and nested. The original courtyard and laboratory instantly disappeared in the regular space. It "disappeared" in time - not a physical disappearance, but a concealment at the spatial level. Perceived from the outside world, the spatial coordinates here are just an ordinary open space, without any Chakra fluctuations in the enchantment, and without any trace of the existence of any object.
Rinto raised his hand and did the first round of tests. He condensed a high-intensity Ninjutsu shock wave and hit it in the direction outside the courtyard gate. As soon as the shock wave touched the outermost camouflage layer, it was instantly deflected by the folded space and flew towards the uninhabited airspace without leaving any trace.
Immediately afterwards, he tested the perceptual shielding effect, released his own perception, and simulated the detection of the outside world. As expected, he could only see a false spatial mirror and could not perceive the existence of the core laboratory at all. He even tested it with the Flying Thunder God mark that had been copied before. As soon as the mark came close to the range of the folded space, it was completely disrupted by the coordinate interference configuration and could not lock any position at all.
The first round of testing met expectations perfectly.
He did not stop and did another extreme impact test, simulating more than a dozen Tailed Beast Bomb-level explosive impacts. All attacks were completely consumed in the five-layer deflection and digestion layer. In the core space, not even a trace of vibration could be felt. He even tested the extreme situation of space turbulence, and the folding barrier was as stable as a mountain, with no half-splitting marks.
More importantly, the entire space folding system is perfectly compatible with the energy self-circulation system, constant temperature and humidity experimental environment control system, and sample sealing sterile system he had built before. It did not have any impact on his experiments, and instead made the entire laboratory environment more stable and safer than before.
All tests passed. Rinto calibrated several subtle parameters and archived and recorded the entire system's operating logic, emergency plans, and maintenance parameters.
Now, even if the entire Shinobi World outside explodes, his laboratory will be safe and sound. His research materials, precious samples, and experimental instruments are all hidden in an absolutely safe space mezzanine, and will not be affected by any war.
After doing all this, he patted the dust on his hands and casually removed the soundproof barrier he had added earlier. The explosions and shouts of death outside were still far away, but even if there was no soundproofing, those sounds could not be transmitted into the folded core space. The entire laboratory was so quiet that only the slight hum of the instruments was left.
He walked back to the sterile operating room, put on his gloves, picked up the Rinnegan Black Receiver, and sat back in front of the experimental table. The space folding defense setup just now was just a "hidden risk of external interference" that was easily solved. To him, this was just a small episode that delayed the progress of his experiment for two hours.
The war outside the window is still spreading, and the entire Konoha is struggling in the flames of war. In his world, only the samples under the microscope and the original rules hidden in the Rinnegan Chakra configuration are left.
