The cicadas chirping outside the window were so noisy that people's brains ached. Rinto threw the charcoal pen in his hand on the table irritably, and a long waste line was drawn on the half-drawn Senjutsu adaptation configuration.
The copy of the Senjutsu manuscript left by Jiraiya was spread out on the table, and there were more than a dozen scrapped drafts piled next to it. Some were crumpled and rolled to the door, and some were scratched beyond recognition. He spent almost two days facing the words "Balance of mind, body, and Natural Energy" and deduced seventeen versions of the plan, but they all collapsed.
The configuration of Yin-Yang Release is active and will be dynamically adjusted according to the output of Chakra. However, as soon as Natural Energy comes in, its activity will either be blocked by the frame of Yin Release, or it will be blocked smoothly. Following the path of Yang Release, the entire structure was destroyed, unable to maintain stability for even half a second. He closed his eyes and leaned on the back of the chair, tearing apart the underlying logic of the two systems over and over in his mind. The more he dismantled, the more chaotic he became. Even the movement outside the courtyard door became a little more impatient.
The courtyard door was lightly knocked twice. Before he could answer, the door was pushed open a crack. Kakashi's voice floated in through the crack in the door, with a bit of careless laziness. "Mr. Rinto? I'm not disturbing your work, are you?"
Rinto didn't open his eyes, and said in a firm tone, "Come in if you have anything to say, and don't hang around at the door."
The door was pushed open, and Kakashi walked in slowly. He almost tripped over the paper ball rolling on the ground, but didn't care, and kicked the paper ball to the corner. He held a thick file in his left hand, and held the "Icha Icha Paradise" on the edge of the volume in his right hand.", with a bookmark between his fingertips, he came in and glanced at the mess all over the table and floor, blew a silent whistle, pulled up a small stool by the door and sat down, first put the three-color meatballs in his hand into the empty space at the corner of the table, and was not in a hurry to get down to business.
He just sat quietly for almost half a minute, and he flipped through two pages of the book in his hand. It wasn't until Rinto opened his eyes, frowned and looked at him that he closed the book and smiled, "Seeing that your brows are so furrowed that you can kill a mosquito, are you encountering a problem?"
"You're not here to talk to me about this." Rinto's eyes fell on the file in his arms, "If you have something to say, just tell me and don't waste my time."
"Don't be so hasty." Kakashi put the file on the table and tapped the cover with his fingertips, "As I mentioned to you before, the details of the circulation of Ninjutsu and Chakra that I copied over the years are all compiled here. You can see if it is enough. I will fill in any missing parts."
Rinto glanced at the thickness of the file, did not flip through it in a hurry, and raised his chin. "What exactly happened to your eye?"
"Hey, I've got this old problem." Kakashi casually took off the Forehead Protector from his left eye, revealing the blue eye area, and tugged at the corner of his mouth helplessly, "It's not native. It has never been able to adapt to the meridians. It uses too much of the optic nerve. The pain is so severe, Chakra seems to be leaking, and Tsunade can only be temporarily pressed, but the root cannot be removed. It is also unlucky to say that I have used this broken eye for more than ten years, and it almost cost me half of my life."
He said it casually, with a bit of self-deprecating joke. Just as he was about to add a few more sentences, he saw a light golden light condensed on Rinto's fingertips, and raised his hand towards him. Kakashi raised his eyebrows, but did not stiffen. He sat up straighter naturally and said jokingly, "Can you please take a look at it? If it can be fixed, I won't have to worry about it when I go on missions in the future."
Rinto didn't answer his joke. When Chakra poked his head in, his brows furrowed and relaxed, muttering something like "Yin Release's circulation path is all off" and "the node is almost half an inch wrong." His fingertips hung in mid-air, pausing from time to time. He completely regarded Kakashi next to him as a living specimen, without even looking at his face.
Kakashi was not embarrassed, so he just let him check it. When he had nothing to do, he picked up the notebook on the table and glanced at it. When he saw the content related to Senjutsu written on it, he raised his eyebrows and didn't ask any more questions. He waited quietly.
It took a full ten minutes for Rinto to take back his hand, pick up the pen and start drawing casually on the waste paper. Instead of a neat talisman, he first drew a crooked eye meridian diagram, circled three red circles, and poked the paper with the pen tip: "You usually use Sharingan, Chakra to go through these three nodes, right?"
Kakashi leaned over and took a look, was stunned, and then nodded. "Yes, it has always been like this. Tsunade also said that there is an adaptation problem, and there is no good solution."
"It's all wrong." Rinto's pen drew a new line on the paper, "Changing this path, Chakra's consumption can be reduced by 60%, and the wear and tear on the optic nerve will be reduced by at least half." He penned sharply. Turning around, he drew another simple structure, with sloppy lines but clearly marked nodes, "If you tap this talisman and sew it inside Forehead Protector, it can slowly repair the damaged nerves, and the blockage can be almost unblocked in three months."
"Oh, this is a big help." Kakashi folded the blueprint, carefully stuffed it into the ninja bag, and said with a smile, "Thanks Mr. Rinto, I thought it would take you a long time. Speaking of which, I'll treat you to dinner tonight Ichiraku Ramen? Naruto Tenten was mumbling in my ear, saying that his tonkotsu soup base is amazing, just think of it as my thank you."
"No." Rinto had already opened the file he brought, his head almost buried in it, and he casually refused, "It will waste time."
"No, you have to eat, right?" Kakashi looked at him like this and smiled helplessly, "I just heard Shizune say that you often only eat one mouthful of dry food a day. If you go on like this, your body will collapse first. How can you do research?"
Rinto didn't respond, his fingertips stopped on a certain page of the file, he picked up the pen and made notes in the blank space, completely ignoring him.
Kakashi was not annoyed. He leaned back on the chair and flipped through two more pages of the book. After he finished annotating that page, he slowly added, "By the way, Lord Jiraiya will return to this afternoon." Konoha, aren't you studying Senjutsu? He has seriously revised Senjutsu in Mount Myōboku, and the information in his hand must be more complete than the copy you have."
This sentence finally made Rinto raise his head and the tip of his pen paused. "He will be back today?"
"Yes, follow up on Akatsuki and report back." Kakashi nodded, "If you want to ask about Senjutsu, I'll go back and say hello to you? He is a man who, as long as you treat him to a nice meal, he will tell you anything."
"No need." Rinto frowned, lowered his head to flip through the file again, and muttered, "He will come to me on his own." Tsunade has been staring at his research for a long time. As soon as Jiraiya comes back, he will definitely be urged to come over by Tsunade.
Kakashi smiled and said nothing more. Seeing that his mind was all on the file, he stood up and walked quietly to the door. "Then I won't disturb you. If you lack any Ninjutsu-related data, just come to me at any time. By the way, you can try the meatballs at your leisure. They are sweet and will relieve your fatigue."
Rinto waved his hand without even raising his head. Kakashi closed the door, and just two steps out, he heard the sound of charcoal being slapped on the table again from inside the room. He couldn't help but shake his head - this gentleman really doesn't care about anything except research.
The room became quiet again, leaving only the chirping of cicadas and the rustling of the pen tip across the paper. Rinto finished flipping through the file Kakashi brought, copied the useful Ninjutsu circulation data in his notebook, threw it aside, and picked up the previous draft of Senjutsu.
Just now, Kakashi mentioned Jiraiya, and he felt a little relieved. Mount Myōboku's complete Senjutsu information, as well as Jiraiya's more than ten years of training experience, can just make up for the basic logic he lacks now, but water from afar cannot quench the thirst for nearness, and he still has to solve the current adaptation problem by himself first.
He had just made two strokes, and crossed them out irritably. He got up and went to open the courtyard door to get some air. When he opened the door, he saw three and a half-year-old children crowded under the tree. You pushed me and I pushed you, and they made noises under their breath.
"I want you to go, but I won't go. It's too troublesome." Shikamaru folded his arms with a look of despair on his face, and was pushed to stagger by Ino.
"What are you afraid of! Sakura has been here many times. The gentleman looks cold, but in fact he is not fierce at all!" Ino pushed him hard, "How long has your Shadow Jutsu been stuck? The enemy almost escaped last time on a mission, have you forgotten?"
"That's right." Choji had potato chips stuffed in his mouth, and the chips dropped every time he spoke, and he echoed vaguely, "I finished doubling it last time, and my back hurt for three days, and I couldn't even eat barbecue..."
The three people were pushing and pushing, and when they looked up and saw Rinto opening the door, they froze instantly. The potato chips in Choji's mouth almost choked into the trachea, and his face turned red from coughing. Ino quickly patted his back, and Shikamaru scratched his head with an expression of "It's really troublesome."
Rinto leaned against the door frame, frowning. "I've been hanging around the door for a long time. If I have something to say, I'll leave. If nothing happens, I'll leave. It's so noisy."
"Ah... yes, yes! Hello Mr. Rinto!" Ino was the first to react and bowed quickly, blushing nervously, "The three of us are Chunin of Konoha. My name is Ino Yamanaka, he is Shikamaru Nara, and this is Choji Akimichi. We... we have some problems with cultivation. I want to ask you, will it bother you too much?"
She was stumbling over her words, and after she finished speaking, she pinched Shikamaru hard.
Shikamaru sighed, took a half-step forward resignedly, and said bravely, "That's it, the consumption of my Shadow Imitation Technique and Chakra has never been reduced. When the terrain is complex, the deformation loss is particularly large, and I have adjusted it many times to no avail. I heard from Lady Tsunade that there is relevant logic in the configuration theory you wrote, and I just wanted to ask you if there is any way to optimize it."
"I, my name is Multi-Size Technique. Every time I use it, my muscles are strained. I can't maintain it for a long time. I can't control my weight..." Choji scratched his head and hid the empty potato chip bag behind his back, feeling a little embarrassed.
"I'm Mind Body Switch Technique. My mental energy is always unstable. I either don't have enough time to control it, or I get kicked back by the other person's consciousness, giving me a headache for several days." Ino quickly added.
Rinto After listening, he was silent for two seconds, then stepped aside to get out of the way. "Come in, don't make any noise."
The three people nodded quickly and followed quietly into the room, even breathing softly, for fear of disturbing the manuscripts piled high on the table. Ino looked at the draft papers on the floor, his eyes widened. Before, he had only heard from Sakura that Mr. Rinto was full of research materials, but he was shocked when he saw it with his own eyes - this was not a laboratory, it was simply buried in drawings.
Rinto pulled up a chair and sat down. He didn't rush to give a solution. He raised his chin at Shikamaru first and said, "How do you usually control Chakra? Tell it from beginning to end. The more detailed the better. Don't just talk about the problem, talk about how you do it."
Shikamaru was stunned for a moment, and hurriedly squatted on the ground, drawing the path of the shadow with his fingers, explaining step by step how he usually allocates Chakra, where problems are most likely to occur, and where the losses are greatest. As he spoke, he saw Rinto picked up the pen and drew a Shadow Jutsu and Chakra circulation diagram on the paper. He interrupted him from time to time to ask for details. Occasionally, he would tut and complain, "The node design of your technique is too stupid, and it will cost 30% more."
Shikamaru was a little embarrassed to be told that, he scratched his head and smiled, but he was shocked in his heart - he had practiced the family secret technique for so many years, and when people heard him explain it once, they understood the underlying logic thoroughly, and all the ineffective losses that he didn't even notice were marked out.
After changing Shikamaru's Shadow Jutsu, it was Choji's turn again. Choji didn't quite understand the details of Chakra's circulation. He stumbled and talked for a long time, and his face turned red with anxiety. Rinto was not impatient either. Annoyed, I simply asked him to move Multi-Size Technique, and touched his arm with Chakra fixed on his fingertips, feeling the circulation path of Yang Release. I frowned and changed it for more than half an hour, and gave him a set of auxiliary mental methods that can repair muscles simultaneously, as well as adjust Multi-Size Technique. The node diagram output by Chakra casually mentioned how to control abnormal fat accumulation in the body.
Choji's eyes lit up and he bowed repeatedly. "Thank you! Thank you so much! From now on, I no longer have to worry about eating too much and getting fat, nor do I have to worry about back pain!"
Finally, there is Mind Body Switch Technique from Ino. Rinto is very familiar with Yin Release's mental energy logic. After listening to her talk about two situations where she lost control, she found the problem and drew a small framework for her to stabilize mental energy. He also mentioned how to optimize the output accuracy of mental power, which can double the control distance of Mind Body Switch Technique.
After all three people's problems were solved, the sun was almost setting. Ino took the paper full of marks and was so excited that he bowed repeatedly. "Thank you so much! Mr. Rinto! You have solved the problem that has been bothering us for almost a year in just a short time!"
"Sir, I will ask my mother to send you the barbecue she made tomorrow! It's super delicious!" Choji looked sincere.
"No need." Rinto waved his hand and pointed to the door, "The complete training data of your family's secret technique, as well as the backlash cases, have been sorted out and put in the mailbox at the door. No need to do anything else."
"Okay! We will deliver it to you early tomorrow morning!" Shikamaru quickly agreed, pulling Ino and Choji who wanted to say more, "Then we won't disturb you, you are busy."
The three people quietly backed out, and as soon as they closed the door, Ino couldn't help lowering his voice and shouted, "Oh my God! Sir, you are so amazing! He explained it to me in just a few words! No wonder Sakura Tenten ran here!"
"It's really amazing." Shikamaru looked at the blueprint in his hand and sighed, "I changed the logic of the technique from the ground up. It's much better than the methods I thought about before. It's no longer troublesome now."
Choji touched his belly and his eyes lit up. "Great! I won't have back pain after doubling it! I can go have barbecue tonight!"
Rinto in the room didn't care whether they left or not. When he changed Choji to Multi-Size Technique, he suddenly thought of a point - Yang Release can guide the activity of cells. Can the same logic be used to guide the circulation path of Natural Energy in the body?
He immediately sat back at the table, picked up the pen and began to draw. His thoughts, which had been stuck for two days, suddenly relaxed. But after just a few strokes, footsteps came from outside the courtyard door again, followed by Sakura's soft voice. "Mr. Rinto? I'm in?"
Rinto didn't look up and said "Yeah" casually.
Sakura pushed the door open and came in, carrying a thermos bucket and a stack of thick envelopes in her hand. She put the thermos bucket on the table first and said helplessly, "Sir, you didn't eat at noon, right? Shizune The chicken soup that sister asked the canteen to stew for you is still hot. Please drink some quickly."
She said, putting the stack of envelopes on the table, but couldn't help but laugh, "Your mailbox is almost full. I just passed by and collected it for you. Most of them are cases asked by doctors and nurses in the hospital, and there are also questions sent by medical ninja entrustees from other ninja villages, and... well, some thank you letters written by villagers, I have put them here for you."
Rinto raised his eyes and glanced at the pile of envelopes, frowning. "Throw it away just as it was written in the book. There is no need to bring it to me."
"I have screened it, and I have replied to all the letters in the book. The rest are some special difficult cases, and there are also a few rare Chakra backlash cases. I think they may be useful for your research, so I brought them to you." Sakura opened the thermos bucket and pushed it to his hand, "You drink the soup first, it will taste fishy when it's cold. When I came in just now, I saw Mr. Kakashi, and he said you haven't eaten well in the past two days."
Rinto did not move. He flipped through the top few cases first. They were indeed special cases that were not covered in the book. He flipped through them casually, picked out the ones with research value and put them aside. He pushed the rest to Sakura: "For these, you can follow the repair logic I gave you before and change the adaptation plan. You don't need to ask me."
"Okay." Sakura nodded, looking at the whites of his eyes that were red from the sleep, and couldn't help but persuade him, "Sir, no matter how busy you are, you still have to eat and sleep. Lady Tsunade asked me yesterday if you Tenten stayed up all night. If you continue like this, your body will be broken."
"Yeah, I got it." Rinto responded casually, his eyes fell back on Senjutsu's draft, and he kept writing in his hand, obviously not taking these words to heart.
Sakura sighed helplessly, not daring to disturb him with any more words. He helped to pick up the waste paper on the ground, arranged the classics on the table in order, put away the rotten dry food that he had not touched before, and quietly left.
When the room became quiet again, it was already dark. Rinto took two sips of the almost cold chicken soup and pushed the thermos bucket aside. His mind was filled with the Natural Energy guidance logic that he had just thought of. He changed the drawing and changed the drawing again for most of the night.
Early the next morning, he had just finished drawing the first version of the adaptation plan and was about to find something to try the effect when another person came outside the courtyard gate.
Not Naruto, nor Jiraiya, but a strange man in a white coat and glasses, with a gentle smile on his face. He stood at the door of the courtyard, neither knocking nor speaking, but waiting quietly, like a passerby passing by.
Rinto only noticed him when he opened the door. His brows instantly wrinkled. He recognized this person, Kabuto Yakushi, Orochimaru.
"Mr. Rinto, hello." Kabuto bowed slightly, his tone was just the right amount of respect, and he didn't go overboard in the slightest, "I'm sorry to bother you."
"Is something wrong?" Rinto leaned against the door frame, not letting him in. The impatience in his tone was clear. He had no interest in dealing with Orochimaru's people, let alone getting into trouble and delaying his research.
"I was entrusted by Lord Orochimaru to negotiate a deal with you." Kabuto's tone was very calm, and he was interrupted by Rinto just after he finished speaking.
"Not interested." Rinto turned around and was about to close the door.
"Sir, don't refuse in a hurry." Kabuto quickly took a step forward and spoke faster, "Lord Orochimaru knows that you have been studying Senjutsu recently, and the nature of Cursed Seal. He has Ryūchi Cave in his hand Senjutsu's complete training information, as well as more than ten years of Cursed Seal research data, including the adaptation records of all experimental subjects, backlash cases, and the complete logic of Senjutsu's energy alienation. Only he has these things, the entire Shinobi World."
The action of closing the door paused.
Rinto's fingertips stopped on the edge of the door, and his heart moved. What he lacks most now is the complete experimental data on the combination of Senjutsu and the human body. Jiraiya's handbook only contains personal cultivation experience, not There are systematic experimental records, and Cursed Seal of Orochimaru is essentially a human application experiment of Senjutsu energy. The complete data of more than ten years can just fill in the missing piece of the puzzle.
He turned around and looked at Kabuto again, his eyes a little colder. "What does he want?"
The smile on Kabuto's face deepened and he said unhurriedly, "Lord Orochimaru's request is very simple. The hands, meridians and soul-bound nodes that were sealed by Third Hokage with Reaper Death Seal were all destroyed. Lady Tsunade can only alleviate it, but cannot cure it. Your Yang Release technology is the only one that can solve this problem."
He paused and added, "In addition, he also wants to ask you to give us a set of adaptation ideas for Living Corpse Reincarnation's soul and body rejection. Of course, we will deal in stages. We will first give you the basic information of Ryūchi Cave Senjutsu and the first half of Cursed Seal's experimental records, and you will give us a complete plan for repairing the hands. After confirming that the plan is effective, we will give you all the remaining information, and then you will give us the adaptation ideas."
Rinto was silent for a few seconds. Reaper Death Seal's damage involved the binding of the soul and meridians, which was a bit troublesome, but it was not impossible. The information in Orochimaru's hand was very attractive to him and could save him at least half a year of detours.
"Okay." He said, his tone calm, "But there are two conditions. First, a transaction is a transaction. You are not allowed to disturb me in my laboratory again, and you are not allowed to let people from Orochimaru cause trouble around Konoha, otherwise I will directly dismantle all your experimental data and the Cursed Seal system. Second, the data cannot be adulterated. If one data is missing, the transaction will be invalid."
The smile on Kabuto's face became even thicker, and he quickly took out a sealed scroll from his arms and handed it over with both hands. "Don't worry, Lord Orochimaru is sincerely dealing with you. The information is absolutely complete and true, without any adulteration. This is the first part of the information, you can verify it first."
Rinto took the scroll, weighed it, and stuffed it into his pocket.
"The plan will be given to you in three days." He looked at his pocket and pointed to the mailbox at the door, "When the time comes, put the remaining information here and don't come in."
"Okay, I won't disturb your research at all." Kabuto bowed and saluted again, turned around and left without saying another word, his steps were very light, and he quickly disappeared around the corner of the street.
Rinto closed the door, walked quickly back into the house, and immediately opened the scroll. The content inside was more detailed than he expected. From Ryūchi Cave Senjutsu's Natural Energy absorption method, Cursed Seal's production principles, and complete records of hundreds of experimental subjects, everything is down to detail, all of which are the result of more than ten years of research effort by Orochimaru.
The more he looked at it, the brighter his eyes became. The Senjutsu adaptation problem that had been stuck for two days had solved several key nodes in an instant. It turned out that the fusion of Natural Energy and human cells did not rely on forced balance, but on anchoring, which matched the structural logic of his Yin-Yang Release.
Rinto spread the scroll on the table and picked up the pen. The dozens of previously scrapped plans finally had a clear direction for optimization. The sun outside the window rose and set, but he didn't even move. The oil lamp in the room went on and off, off and on again, and the rustling of the pen tip across the paper never stopped.
He didn't notice at all that in Hokage's office, Jiraiya, who had just returned to Konoha, was being pressed on the shoulder by Tsunade, repeatedly telling him, "Your Mount Myōboku Don't hide the Senjutsu information, send it all to Rinto! If he can thoroughly study Senjutsu, we will have a huge trump card against Akatsuki in the future!"
