After the complete experimental data of Senjutsu's dynamic balance model was archived, Rinto did not start a new subject immediately. Instead, he spread out Jiraiya's Senjutsu notes and Mount Myōboku's cultivation records of past immortals on the experimental table.
In the handbook, Jiraiya used a self-deprecating tone to write down his dilemma when practicing Sage Mode: Even if he has mastered perfect balance, once he is distracted in actual combat, alienation of frog eyes and frog webs will occur, which not only affects the movements, but also It will also expose the activation status of Sage Mode; in the records of Mount Myōboku, there are many cultivators who have irreversibly transformed into frogs due to their long-term absorption of Natural Energy, and even completely lost their human characteristics.
This is the second pain point that traditional Senjutsu practice cannot avoid - the assimilation backlash of Natural Energy.
The core of Senjutsu inheritance of Mount Myōboku is to "same frequency with nature", allowing one's own mental and physical energy to fit the frequency of Natural Energy, thereby achieving efficient absorption. But Natural Energy of Mount Myōboku already carries the life mark of the psychic beast Toad, and is on the same frequency for a long time By absorbing it, the cultivator's body will be unconsciously assimilated by the characteristics of Toad, causing side effects of frog transformation and frog eyes; not to mention that in places where the concentration of Natural Energy is insufficient, the cultivator needs to forcibly amplify his or her perception of Natural Energy. If you are not careful, your mind will be eroded by the complex Natural Energy, or uncontrollable alienation will occur.
The previous dynamic balance model solved the core risk of out-of-control petrochemicals, but did not solve the problem of "same frequency backlash". What Rinto wants to do is to completely overturn the traditional logic of "same frequency as nature" and build a Natural Energy accurate absorption system that does not require the same frequency, no contact, and no alienation, which is the new topic he set before.
He put down the notebook, picked up the charcoal, and wrote on the blank slate the core contradiction of the traditional absorption method: The "same-frequency absorption" of the traditional Senjutsu is for practitioners to actively lower their own energy barriers to adapt to the frequency of Natural Energy. It is equivalent to actively opening the city gate to allow the energy from the outside to flow in, which will naturally entrain impurities, imprints, and even reverse assimilation.
The logic of the new system he wants to design must be completely reversed - not active adaptation, but precise capture, directional purification, and lossless transformation.
There is no need for practitioners to sit and meditate to conform to the natural frequency, no need for Toad Oil to assist in amplifying perception, or even the need to deliberately concentrate. Only relying on the solidified configuration, it can actively capture the free Natural Energy from the air, filter out the impurities, life marks, and stray frequencies, leaving only the purest Natural Energy body, and then send it into the previous dynamic balance closed loop to complete assimilation and transformation.
This system cuts off the possibility of alienation from the root. Since it does not need to be on the same frequency as Natural Energy, it will naturally not be assimilated by the Toad imprint of Mount Myōboku, let alone stray Natural Energy corrodes the mind; even in Natural Energy thin battlefields and indoors, it can rely on the active capture of the configuration to steadily absorb Natural Energy, completely breaking the strict environmental requirements for Senjutsu cultivation.
The core logic of the theoretical framework is finalized, followed by precise configuration design and formula derivation.
Rinto first designed a multi-level capture and filtering configuration based on the previous Natural Energy conversion experimental data: the outermost layer is a wide-area Natural Energy capture array, which can capture free Natural Energy in the surrounding environment without blind spots, and can continue to enrich even if the concentration is extremely low; the middle layer is a directional purification module, which can accurately filter out All non-body impurities contained in Natural Energy, whether it is the life mark of Toad or other stray energy in the environment, will be directly stripped and dispersed; the innermost layer is a lossless conversion interface, and the purified pure Natural Energy will be directly connected to the yin and yang double anchor points of the dynamic balance model to complete the condensation of Senjutsu Chakra.
In order to ensure that this system can adapt to different people, he also added an adjustable parameter module. The capture rate, purification accuracy, and enrichment range can all be automatically adapted according to the user's Chakra amount and assimilation ability. Even Chunin with a low Chakra amount can be used safely without energy overload problems.
For a whole morning, Rinto was immersed in the derivation and optimization of the configuration. He overturned three major framework designs, modified dozens of core parameters, and optimized the capture efficiency, purification accuracy, and energy consumption ratio to the extreme. The final product is not a set of mental methods that require long-term practice, but a set that can Directly carve into the solidified configuration of the Chakra cycle. Even those who have no foundation in Senjutsu can safely and stably absorb Natural Energy and condense Senjutsu Chakra as long as they carve into this set of configurations and cooperate with the previous dynamic balance anchor points.
The theory and configuration design are completed, and the next step is experimental verification.
Rinto did not directly test it on himself, but first conducted an in vitro energy capture experiment. He built a miniature capture and purification configuration in a sealed incubator, accurately controlled the concentration of Natural Energy in the box, simulated low-concentration environments in different scenes such as battlefields, indoors, and rainy days, and recorded the capture efficiency and purification accuracy of the configuration in real time.
The experimental data is in perfect line with expectations: even in a sealed environment where the concentration of Natural Energy is only one percent of Mount Myōboku, the configuration can stably capture and enrich Natural Energy, the purification accuracy has reached 99.99%. In the filtered Natural Energy, no stray marks and frequencies can be detected at all, and the purity far exceeds the Natural Energy obtained by the traditional same-frequency absorption method.
After the in vitro experimental verification was completed, Rinto started the autologous test. He first integrated the previous yin and yang double anchor point configuration and the newly designed capture and purification configuration into a complete Senjutsu system, which was engraved into his own Chakra cycle. Then he removed all deliberate mental control, and while looking through the previous case files in front of the experimental table, he allowed the configuration to run automatically in the background.
He could clearly feel that the free Natural Energy in the air was silently captured and purified by the configuration, and was continuously sent into the body, where it was quickly assimilated into stable Senjutsu Chakra by the double anchor points of yin and yang. He did not need to devote any energy to the whole process. Controlling balance, there is no need to adjust breathing to match the natural frequency. Even if his attention is completely focused on the file, the condensation of Senjutsu Chakra is proceeding steadily and continuously. There is no free Natural Energy in the body, and there is no sign of being assimilated.
He even deliberately walked to the sealed room at the innermost side of the laboratory - it was wrapped in four layers of barriers and almost isolated from the outside world. The concentration of Natural Energy was extremely low. However, the configuration was still operating stably, and the capture rate only dropped slightly, which did not affect the continued condensation of Senjutsu Chakra at all.
More importantly, he continued to operate the Senjutsu system for two full hours, and there was no sign of frog transformation or frog eyes on his body. Even the lines of his eyeballs did not change at all. His breath was no different from usual, and others could not detect it at all. Until he is running the Senjutsu Chakra. In the traditional Senjutsu, once the Sage Mode is started, there will inevitably be problems with appearance changes and a surge in aura. In this system, it is completely solved.
Rinto stopped the operation of the configuration, recorded and archived all the data and sensory details of the self-experiment one by one, and finally wrote the conclusion: the non-same-frequency Natural Energy absorption system was successfully verified, completely solving the alienation and backlash problem of the traditional Senjutsu, breaking the limitations of environment and concentration, and perfectly adapting to the dynamic balance model. The safety threshold and applicable scenarios are far higher than the traditional Senjutsu.
He put down the charcoal and brushed Jiraiya's Senjutsu notebook with his fingertips again. In the notebook, Jiraiya wrote that in order to eliminate the side effects of frog transformation, he It took a whole year to polish it, but it was still inevitable that mistakes would appear in actual combat. If Jiraiya was still there, this system would make his Sage Mode no longer have any worries.
The temperature of his fingertips stayed on the page. Rinto was silent for a few seconds. Then he closed the notebook and suppressed the slight sadness. He raised his hand and split the complete Senjutsu system into a basic version and a complete version - the basic version only retained the most The core safety configuration is enough for Mount Myōboku's cultivators to avoid petrification and alienation risks and fulfill his agreement with Sage Fukasaku; the full version is a full-featured system that integrates dynamic balance, automatic capture, and traceless operation, and is the result of his own research.
He copied the configuration drawings and parameters of the basic version separately on a slate and placed them on the corner of the table. When Sage Fukasaku comes to send data next time, just give it to him directly.
After doing all this, Rinto filed and locked all Senjutsu's research materials, and his eyes fell on Konoha Hospital's difficult case files that Tsunade had sent before.
He has thoroughly understood the core rules of Senjutsu. Next, he wants to see if this system that can accurately control the activity of Natural Energy and Yang Release can solve the problem of extreme damage that conventional Medical Ninjutsu is helpless.
