The knock on the door outside the courtyard was very light, and it was paused for fear of disturbing the people in the house. Then came the cautious voice of Ishikawa, which came through the wooden door, with the soft sound of the food box colliding, "Mr. Rinto? The food has been delivered to you, can you open the door? I also brought you some herbs to treat bruises. You might have picked it up on your way just now, so it's always good to have it ready."
The sound of the pen tip scratching across the paper in the room stopped.
Rinto frowned, put the half-drawn draft of the configuration under the notebook, and then stood up to open the door. He stayed up for almost two days and one night, with red bloodshot eyes on his eyes and no expression on his face. He stepped aside and said, "Just put it on the table."
Ishikawa hurriedly came in with a food box, followed by a half-year-old child, holding a wooden basin in his hand, filled with steaming hot water, and a clean coarse cloth. Ishikawa put the food box on the table by the window, and while serving the food outside, he talked casually. He spoke in a fragmented and urgent manner, with no focus, and was all trivial matters:
"All the fires in the village have been put out, except for the collapse of more than a dozen stilted buildings. Fortunately, not many villagers were seriously injured. Thanks to the fire you just put out, otherwise it would have burned the houses next to the ancestral hall. I can't imagine the consequences."
"Elder Matsushita was walking around the door three times just now. He wanted to come in and say thank you, but he couldn't help but feel ashamed. He went back and took medicine for his injuries in the middle of the night, and asked me to bring it to you. There are also two clean changes of clothes, both of which are newly made and have never been worn."
"The kitchen has stewed pheasant soup with some herbs from the rainforest. It's nourishing for your body. You've been simmering it for so long, so take a few sips while it's hot. There's also this potato cake, which was made by the grandmothers in the village. It's sweet and not greasy."
He rambled on for a long time, arranging everything neatly including dishes, soups, pastries, medicine bags, and a change of clothes. When he looked up, he saw that Rinto had not moved his chopsticks, and was sitting back at the table, flipping through the book full of formulas and lines, his brows still furrowed, obviously not listening to what he said.
Ishikawa was not annoyed. He put the hot water basin on the shelf next to him and said in a low voice, "Sir, please eat the hot food first. The food will become fishy when it is cold. You can draw in the notebook at any time, so you need to rest your stomach first."
"Hmm." Rinto responded casually, running his fingertips across the page, his eyes fell on the Yin-Yang Release fusion configuration that he had drawn at the inn, and he muttered, "No... the nodes are still too dense, and the loss of Chakra circulation still cannot be reduced. Even with Senjutsu to replenish energy, long-term use will still cause cell damage..."
Ishikawa stood nearby, listening to the terms that he didn't understand at all, and didn't dare to disturb him. He could only arrange the dishes and chopsticks gently, add some lamp oil to the lamp, and brighten the wick. He has lived for more than fifty years, and has never I have seen such a person before - at the entrance of the village just now, he easily drove away three S-class traitorous ninjas who could not even stop the whole village. He then turned around and hid in the room, frowning at a few pieces of paper, with nothing in his eyes except those lines that looked like ghost drawings.
After almost ten minutes, Rinto put down his pen, walked to the table, sat down, picked up his chopsticks and took a sip of the soup. The chicken soup was so simmered that the warmth slid down his throat, and the fatigue from staying up all night slowly came back.
Ishikawa saw that he finally moved his chopsticks, and then he breathed a sigh of relief. After hesitating for a long time, he finally asked, "Sir, you... where are you going to go next? You said before that you would leave early tomorrow morning. The rain forest has been too peaceful recently. Akatsuki's people, Konoha's spies, and some black market bounty hunters are all wandering around the border. It's too dangerous for you to go alone."
Rinto was chewing potato cake without raising his head. "I don't know, let's find a quiet place first and polish the remaining configuration."
"Then you might as well stay with us!" Ishikawa answered immediately, his eyes brightening, "We will build you the best laboratory, which is soundproof and anti-disturbing. We will find all the consumables and information you want Takigakure for you! No one in the village dares to disturb you, and the patrol team can also help you keep out all the messy spies. You can do whatever you want to study, how nice!"
His words were not polite, but sincere. Not to mention that Rinto saved the entire village, but based on his understanding of Yang Release, being able to stay in Takigakure would be of immeasurable benefit to the entire village.
Rinto shook his head and refused directly. "No need. Takigakure's information is too little and not enough."
His research has reached the bottleneck of Yin-Yang Release integration. Takigakure's information about Yang Release has been clearly dismantled by him, and there is no point in leaving it here.
The light on Ishikawa's face dimmed, but he did not dare to persuade any more. He could only sigh, "Then... then at least wait until we find out the situation at the border before leaving. At least let us send two ninjas to escort you, otherwise we are really worried. By the way, you can take this."
He took out a wooden sign from his arms, with Takigakure's water mark engraved on it, and Rinto's name. "This is our Takigakure's most advanced pass token, covering all stations and checkpoints in the entire Land of Waterfalls territory., the patrol team will not stop you after seeing this token. If you need anything, go to the local Takigakure stronghold and they will help you. Also, I have said hello to all the border patrol teams. If you encounter any trouble, just crush the messenger in the token and we can rush over in half an hour."
Rinto took the token, weighed it, stuffed it into the side pocket of his backpack, and nodded. "Thank you."
"You're welcome, you're welcome!" Ishikawa waved his hands quickly, his face turning red, "You have helped us Takigakure so much, so this is nothing."
He stood beside him for a while, and when he saw that Rinto had finished eating, he quickly put away the dishes, fearing to disturb his research, and quietly carried the food box to leave. He walked to the door, stopped again, and turned around and said, "Sir, if you need anything, even in the middle of the night, just knock on the door next door. I have someone to guard the door next door and be on call."
"Yeah." Rinto had already sat back in front of the desk and picked up the pen without raising his head.
Ishikawa Gently closed the courtyard door, and the courtyard returned to silence. The only sound left was the rustling of the pen tip across the paper, and the occasional small sound from outside the window of the villagers cleaning up the mess.
Rinto didn't pay attention to outside matters. He drew the newly perfected Yin-Yang Release configuration on the paper again, and spread out the core mental techniques that he had previously copied in the Takigakure secret biography next to him for comparison.
The more he looked, the tighter his frown became.
The configuration is clear, but the core bottleneck is still there - no matter how he optimizes it, he can't get around the "upper limit of the total amount of Chakra". His Yin-Yang Release configuration requires extremely high precision control of Chakra, and small-scale disassembly, repair, and shaping are no problem. However, once a large-scale configuration rewrite is required, or it is maintained for a long time, its own physical and mental energy cannot support it at all.
The only direction to break the situation is "Natural Energy" written in Jiraiya's information, which is Senjutsu. But Senjutsu's balancing logic only has some fragmented information, without enough samples and practical data, and it is impossible to figure it out behind closed doors.
What's even more annoying is that the troubles never stop. After escaping from Konoha, Danzo's roots, Orochimaru's Sound Ninja, and Akatsuki's people came to him one after another, interrupting his research ideas every time. Sometimes nodes that had been stuck for several days would be completely forgotten and had to be deduced all over again.
He put the pen down on the table irritably, leaned back on the chair, closed his eyes and rubbed the center of his brow.
How can we solve these troubles once and for all? How can we get enough circulation data of Chakra with different physiques to improve his basic theory?
Rinto opened his eyes and glanced at the pile of manuscripts piled on the table. There were transcripts of the Second Hokage manuscript he brought from Konoha, fragments of the Land of Whirlpools classics, Takigakure's secret notes, and various experimental data and trial and error records that he had jotted down along the way.
In his eyes, these things were imperfect drafts, but to the entire Shinobi World ninjas, they were things that could subvert their perceptions.
An idea suddenly popped up in his mind.
What if... he made these basic, non-core research results public?
He sat up straight, tapped his fingertips on the table, and quickly ran through this idea in his mind:
Shinobi World people's understanding of Chakra is really too backward. Most ninjas don't even understand the basic circulation logic of Chakra. They only know how to follow Hand Seals taught by their predecessors.. When Ninjutsu was released, his practice went awry. He was injured and even died suddenly, and even the cause could not be found. These erroneous practices, in turn, left him without enough and correct verification samples for the general logic of Chakra.
If the basic configuration of Chakra, the repair logic of Yang Release, and the non-combat applications of Chakra, these basic theories are made public and the underlying cognition is corrected, all Shinobi World ninjas will become his "practical samples". Their training feedback and application cases are the best data for him to perfect the theory. It is much more efficient than trying them one by one by himself.
More importantly, once these things are made public, he will no longer be a "dangerous Konoha traitor" in the eyes of the major ninja villages, but someone who can bring them real benefits. Whether it is Konoha or the other four major ninja villages, they will no longer let Danzo and bounty hunters harass him, and will even take the initiative to help him block these troubles and give him a clean research environment.
The more he thought about this idea, the smoother it became. The previous irritability disappeared. His eyes lit up again. He picked up the charcoal pen and wrote down a few book titles on the blank page.
"On Basic Chakra Configurations"
"Guide to Yang Release Fundamentals and Body Repair"
"Collection of Non-Combat Applications of Chakra"
What he wants to write is not some secret technique that can improve combat effectiveness, but the lowest basic theory that can benefit the entire Shinobi World. He does not need to rely on this to become famous, nor does he need to rely on this to exchange for power. What he wants is an environment where he can conduct research quietly and enough practical data.
Rinto became more and more excited as he wrote, and the ideas that had been stuck for a long time became smoother. He even forgot about fatigue and lay on the desk. He first listed the outline of each book, listing the content to be written, the core secrets to be avoided, and the basic logic to be explained clearly.
The sky outside the window is slowly getting brighter.
The morning mist drifted in through the cracks in the window, bringing with it the fragrance of vegetation in the rainforest, but Rinto didn't notice it at all. He could only see the writing on the paper. Even when the courtyard door was gently pushed open and Ishikawa brought breakfast in, he didn't even look up.
Ishikawa Watching him stay up all night, the redness in his eyes became heavier, but he was not tired at all. Instead, he was very energetic. There was a new paper full of words on the table, so he didn't dare to disturb him. He put the breakfast on the table gently and quietly left.
It wasn't until the sun rose above his head that Rinto put down his pen, looked at the complete framework of the three books listed, and breathed a long sigh of relief.
The framework was set, and all that was left was to complete the content. With his familiarity with these theories, he could finish it in three days at most.
He stood up and stretched his numb legs, and then noticed that the breakfast on the table was already cold. He didn't care, picked up the cold potato cake and took a few bites, then walked to the entrance of the courtyard and shouted to the Takigakure ninja who was guarding not far away, "Go and call your elder."
The ninja was stunned for a moment, nodded immediately, turned around and ran deeper into the village. After a while, Ishikawa ran over panting. When he entered the door, he asked, "Sir, what's the matter? Are you missing something? Or do you feel uncomfortable somewhere?"
"I want to write a few books." Rinto looked at him with a calm tone, "After I finish writing, I need your help. I will make dozens of copies and send them to Five Great Shinobi Villages's Ninja Academy, the hospital, and the senior officials of various ninja villages through your caravans and inns."
Ishikawa was stunned, blinked, and didn't react for a long time. "Write, write a book? Send, send to Five Great Shinobi Villages? Sir, what are you writing?"
"The basic theory of Chakra, as well as the content of medical restoration and people's livelihood applications." Rinto simply explained, "You don't need to worry about the content, just send it out for me. When sending it, please indicate that the content can be copied and disseminated at will, and there is no need to keep it confidential."
Ishikawa is even more confused.
Shinobi World, who doesn't hide his secret skills and research very closely, for fear of being learned by others? Even Takigakure's Yang Release secret skills are passed down to the inside but not to outsiders, and have been guarded for hundreds of years. But Rinto wants to make all his research results public and let anyone copy and spread them?
He hesitated for a long time, then asked cautiously, "Sir, this... this is something you have worked so hard to research, and now it's all made public? What if someone uses it indiscriminately, or... or someone steals the results?"
"It doesn't matter." Rinto waved his hand, not caring, "I won't write down the core things. What's public is the basic logic. They can use it and give me some feedback on practical data, that's enough."
Ishikawa looked at the matter-of-fact look on his face, and finally understood that the person in front of him didn't care about any achievements or reputation at all. All he cared about were formulas and theories that he couldn't understand. He opened his mouth, and finally nodded. "Okay! No problem! After you finish writing, I will personally watch and copy it, and I will ensure that there are no more than one copy, and all will be sent to the place you said!"
"Yes." Rinto nodded, turned around and walked into the room, "Don't let anyone disturb me. I will give you the manuscript in three days."
After saying that, he closed the door, sat back in front of the desk, and picked up the pen.
Ishikawa stood in the yard, looked at the closed door, shook his head helplessly, and couldn't help but smile. He had never seen such a person in his whole life, and had never thought that there would be ninjas who were willing to share their research results with the world Shinobi World for free.
He quietly exited the courtyard, instructing the ninjas guarding the door not to leave even half a step, and absolutely not to let anyone disturb Mr. Rinto.
The oil lamp in the room was lit again.
Rinto held the pen, the tip of the pen crossed the paper, and wrote the first line of "On Basic Chakra Configurations":
"Chakra is a fusion product of spiritual energy and physical energy. Its essence is life energy that can be guided in a regular manner..."
