When it was almost dawn, Rinto finished turning Orochimaru's scroll.
The wick of the oil lamp was burnt black, and the room was filled with a faint smell of oil. There was a new pile of draft paper on the table, which was filled with the node formulas of Natural Energy and cell anchoring. He leaned back on the chair, closed his eyes and rubbed his sore eye sockets. He went through hundreds of sets of data from the Cursed Seal experiment in his mind, but his brows still did not loosen.
Orochimaru's information did fill the gap in his knowledge, but Ryūchi Cave's Senjutsu took the path of forced fusion and alienated cells, and his Yin-Yang Release's adaptability is extremely poor, and practicing it will only destroy his own configuration. The only thing that is useful is the backlash records of those experimental subjects, which help him avoid more than a dozen fatal points of Natural Energy fusion, but the core balance problem is still unresolved.
He threw the scroll aside casually, picked up the previously scrapped draft of Senjutsu, and crossed out an entire page of the plan. The sky outside the window had already dawned, and the morning breeze made the window paper sway, carrying the smoke of Konoha in the early morning, but he didn't notice it at all. His fingertips were scratching on the table unconsciously, and the parameters of the anchor nodes were still spinning in his mind.
Just sitting like this until the sun rose, there was a loud knock on the door, followed by Jiraiya's voice, and the careless smile could be heard through the door, "Mr. Rinto is there? Lady Tsunade asked me to come for a visit, and I brought some good things by the way."
Rinto frowned, stood up and opened the door. As soon as he opened the door, he saw Jiraiya carrying a wine gourd, an oil paper bag in his hand, and two thick notebooks in his other hand. His hair was messy, his face looked tired from the journey, but his eyes were bright.
Jiraiya squeezed in sideways without waiting for his invitation. He almost tripped over a ball of paper on the ground as soon as he took two steps. He quickly held on to the door frame, glanced down at the drafts on the floor, and whistled. "Hey, your room is more messy than Orochimaru's laboratory. I said, you should clean it up at least, don't turn around and throw yourself."
Rinto didn't answer his words, his eyes fell on the two notebooks in his hand. "Did you bring Mount Myōboku's Senjutsu information?"
"Hey, don't worry." Jiraiya put the oil paper bag on the table, opened it and found two plates of appetizers, then uncorked the wine gourd and poured himself a glass of wine, "I just returned to Konoha, was pressed on the shoulder by Tsunade, saying that you were studying Senjutsu, and asked me to bring you all the money. Don't rush to read the information, let's chat first?"
As he spoke, he pushed the wine glass in front of Rinto. Rinto didn't even look at it. He pulled up a chair and sat down. He stretched out his hand and said, "Give me the information."
Jiraiya smiled helplessly and handed over the two manuscripts, "Okay, okay, here they are. These are all the experiences I have memorized after practicing in Mount Myōboku for so many years, as well as the basic Senjutsu methods taught by Sage Fukasaku. Even the embarrassing things I did when I was practicing were recorded in them. They are more comprehensive than those manuscripts in your hand."
Rinto took the manuscript and opened it immediately. Jiraiya's manuscript was written very casually and was not a formal theory. There were one sentence here and there, a method of cultivation, pitfalls that had been stepped on, and Mount Myōboku The details taught by Toad from E, even mixed with a few limericks written by himself, are completely different from the scroll full of cold data from Orochimaru.
But these random records just make up for what Rinto lacks the most - the somatosensory details absorbed by Natural Energy, as well as the signs of loss of balance and adjustment skills. These things will not appear in rigorous experimental records. Only those who have practiced hard for more than ten years will notice.
Jiraiya was sitting next to him, drinking wine and eating appetizers, watching Rinto dive into the notebook, completely treating him as nothing, not getting annoyed, and just talking to himself. "Tsunade You told me that you are really awesome. A few books have completely overturned the entire understanding of Shinobi World. When I was outside, even the ninjas of Sunagakure were talking about the repair guide you wrote and saved many people."
Rinto didn't respond. He ran his fingers across the page and muttered words. From time to time, he picked up the pen and made two additions to his draft. He could only see the contents of the notebook.
"Speaking of it, Senjutsu looks simple and just balances the three. But when you really practice it, there are a lot of pitfalls." Jiraiya gnawed some peanuts and said slowly, "When I first started practicing, I almost turned my arms to stone. Yes, it was Sage Fukasaku who helped me rescue it. Don't try it behind closed doors. Just relying on deductions is useless. If you really want to absorb Natural Energy, you have to find a place with a strong concentration of Natural Energy and try it slowly. Don't rush."
Rinto still didn't raise his head and just said "hmm" casually, obviously not taking it seriously.
Jiraiya sighed and said, "By the way, I came back this time with new news about Akatsuki. They have already started to arrest Tailed Beast, Sunagakure's One-Tail Shukaku was kidnapped by two people named Deidara and Xie in their organization. Sunagakure is now in chaos, and they just sent someone to Konoha to ask for help."
This sentence finally made Rinto raise his head and frown. "Are they coming Konoha?"
"Not yet." Jiraiya shook his head and looked a little more serious, "But their goal is all Tailed Beast, Naruto will be Nine-Tails Jinchuriki, sooner or later I will keep an eye on him. When I come back this time, I also plan to take Naruto out to practice. On the one hand, I will avoid Akatsuki, and on the other hand, I will teach him how to practice Senjutsu. I can't wait for others to come knocking on my door."
Rinto's frown relaxed, and he lowered his head to look at the manuscript again, leaving only one sentence. "Don't fight at Konoha, just disturb me for research."
Jiraiya was stunned for a moment, then laughed loudly, "You kid, you really don't take anything into your heart except research. Okay, let's try not to make any noise Konoha. But then again, If you really study Senjutsu thoroughly, and Akatsuki really comes over in the future, you can't just watch Konoha being blown up, and you won't be able to save your laboratory by then."
"If they dare to bomb, I will dismantle their Chakra node." Rinto said calmly, and the pen in his hand did not stop. He had already begun to adjust his own Senjutsu adaptation plan on the draft based on Mount Myōboku's method.
Jiraiya looked at him like this and shook his head helplessly. He had traveled all over the country for so many years and had seen all kinds of weirdos, but he had never seen anyone like Rinto - he obviously had the ability to shake the entire Shinobi World, but he only saw formulas and blueprints. Power, reputation, and strength were not as important to him as a smooth configuration.
He didn't say anything more, and sat quietly drinking next to him. Occasionally he looked up at Rinto, watching him frown at the notes and drafts, and sometimes his eyes lit up. He was completely immersed in his own world.
At this moment, there was a banging sound outside the courtyard door, followed by Naruto's shouting. Before anyone came in, the voice floated in. "Mr. Rinto! Mr. Rinto! I sent you the sample! There is one more thing I want to ask you!"
As soon as he finished speaking, the door of the courtyard was pushed open, and Naruto rushed in, holding a sealed sample tube in his hand and a large backpack on his back. As soon as he rushed into the room, he saw Jiraiya sitting next to him. He was stunned for a moment. "Pervy Sage? Why are you here?"
"You boy, you are so frizzy, didn't you see that others were busy?" Jiraiya glared at him, "You almost broke the door."
"Oh, I'm in a hurry!" Naruto scratched his head, walked quickly to the table, put the sample tube in front of Rinto, and said expectantly, "Sir, this is the Nine-Tails Chakra sample you asked for, and the Cursed Seal sample that Sasuke asked someone to bring back last time. I got them for you!"
Rinto didn't even raise his head. He reached for the sample tube and put it aside casually. He only said two words: "The talisman is in the mailbox, take it yourself."
"Oh, okay!" Naruto nodded quickly, but did not go to get it immediately. Instead, he came over and said with a distressed look, "Sir, I have something else to ask you. I am currently practicing an advanced version of the new Ninjutsu, Rasengan, and I want to use the wind attribute Chakra When and Rasengan are combined, it is necessary to change the form and properties at the same time. I have been practicing for a long time, but I can't control it well. Chakra either falls apart or explodes. Kakashi-sensei has taught me for a long time, but I still haven't figured it out yet."
As he spoke, he gestured hurriedly and talked about the problems he encountered in confusion. One moment he said that Chakra was too loose, and the other moment he said that the shape was not stable. The more he spoke, the more anxious he became, and his face turned red.
Jiraiya was listening next to him, and when he was about to say a few words, he was interrupted by Rinto.
Rinto finally raised his head and glanced at Naruto with a frown. Apparently his train of thought was interrupted by his noise, and his tone was a little impatient. "The essence of Rasengan is the change of form of Chakra. The wind attribute is a change of nature. If you superimpose the two as two things, of course it will explode."
He picked up the pen, drew a circle on the waste paper, and clicked on three nodes. "Starting from the most basic rotation of Chakra, the cutting logic of the wind attribute was embedded. It was not about making the ball first and then adding the wind, but starting from the root. Every strand of Chakra has both form and nature. Do you understand?"
Naruto stared at the circle on the paper, stunned for a long time, his eyes suddenly widened, and he slapped his thigh suddenly. "Oh! So that's it! I have always made Rasengan first, and then added the wind attribute to it, no wonder it's always wrong! Sir, you are so awesome! You nailed it all in one sentence!"
He was so excited that he almost jumped up and bowed repeatedly to Rinto: "Thank you, sir! Thank you so much! I'll go practice now!"
After saying that, he turned around and rushed out the door. After running for two steps, he thought of something. He turned back and put the restraining talisman in the mailbox away, and ran away in a hurry. Before going out, he bumped into the door frame. He grimaced in pain and did not stop. He disappeared in a blink of an eye.
Jiraiya looked at the direction in which he disappeared and smiled helplessly, "This kid is still so frizzy. But thanks to you, he has been stuck on this problem for almost a week. Kakashi and I have talked to him several times, but he has not turned around."
Rinto didn't answer. The train of thought that was interrupted by Naruto suddenly took a turn.
He just told Naruto that changes in form and properties must be integrated from the root and cannot be separated and superimposed. So, isn't the same principle true for Senjutsu and Yin-Yang Release? He had been thinking about how to embed Natural Energy into the already formed Yin-Yang Release configuration. In essence, it is still "superposition", not "fusion", so no wonder it always collapses.
We should start from the most basic Chakra node and embed the balance logic of Natural Energy, so that the three energies of mind, body and nature, from the moment they are integrated, will carry the rules of Yin-Yang Release, instead of first integrating Chakra and then absorbing Natural Energy.
As soon as this idea came up, most of the knots that had been stuck for several days were instantly loosened.
Rinto's eyes lit up. He immediately picked up the pen and started drawing quickly on the new paper. He even completely forgot about Jiraiya next to him. Jiraiya looked at him and was immersed in it again. He smiled and shook his head, stuffed the wine gourd, put the unfinished snacks on the table, got up and left quietly, not forgetting to help him seal the courtyard door when he left.
He finally understood that there was no need to say too many polite words to people like Rinto. All he wanted was research information, and everything else was just a disturbance to him.
The room became quiet again, leaving only the rustle of the pen tip across the paper. Rinto completely lost track of time and flipped through the notebooks brought by Jiraiya. Combining the experimental data of Orochimaru, he adjusted the new fusion plan bit by bit. The discarded draft paper was thrown on the floor. Even the lunch that Sakura brought at noon was cold on the side, and he did not touch it.
It wasn't until the evening that Sakura came over again carrying a thermos bucket, only to find that he hadn't touched a bite of his lunch meal. He sighed helplessly, put the cold meal away, and put the new hot meal next to him. "Sir, no matter how busy you are, you still have to eat. Lord Jiraiya. Have you been here this morning?"
"Well, let's go." Rinto responded casually without raising his head, without stopping the pen in his hand.
"I just met Naruto at the door. He ran to the training ground like crazy, saying that you woke him up and he was going to practice the new Ninjutsu." Sakura said with a smile, and helped him pick up the waste paper balls on the ground and organize them. Looking at the classics scattered on the table, "By the way, your mailbox is full again. I collected it for you. Most of them are cases from the hospital. There are also letters written by the children of the Ninja Academy, saying that they wanted to be a ninja like you after reading your book. There are also vegetables sent by the villagers. I put them in the kitchen for you."
Rinto said "hmm" and didn't take it seriously at all. He had just finished drawing the new fusion framework and was about to deduce it in his mind to see if there were any loopholes.
Sakura looked at his redness getting heavier and heavier, and couldn't help but advise, "Sir, you've been up for almost two days, why don't you take a nap after dinner? Otherwise, your body really won't be able to bear it. Lady Tsunade said that if you keep going through it like this, she will come and collect your pen in person."
"Got it." Rinto responded perfunctorily, tracing his fingertips over the nodes on the draft paper, and frowned again.
The framework is clear, but there is still a problem - the absorption of Natural Energy needs to be synchronized with the environment. It cannot be absorbed sitting in the laboratory. There are many people in Konoha, the Chakra wave is chaotic, and the concentration of Natural Energy is not enough, so it is impossible to verify it in practice.
He stopped writing, leaned back on the chair, frowning and thinking. Where can he find a place where Natural Energy is rich and no one is disturbed? Mount Myōboku? No, if you want to go to Mount Myōboku, you have to deal with Toads, and you have to deal with Jiraiya. It's too troublesome. The mountains and forests on the border of Land of Fire? It's too far away, and it will take time to go back and forth.
Sakura saw him frowning in a daze, thinking that he had encountered another problem in his research, so he didn't dare to disturb him. He opened the lid of the thermos bucket and handed the chopsticks to his hand. "Sir, let's eat first. If you don't eat, it will get cold. If you have any questions, think about it after you eat, and your mind will be clearer."
Rinto took the chopsticks and took two bites of rice absentmindedly, still thinking about where to find a suitable test site. Halfway through the meal, he suddenly put down his chopsticks and stood up to look through the notes left by Jiraiya.
I mentioned in the handbook that the concentration of Valley of the End and Natural Energy around Konoha is not low, but no one usually goes there, and the place is remote and quiet.
Rinto's eyes lit up. Valley of the End is not far from Konoha. If you go back and forth quickly, half a day will be enough. The place is remote and no one will disturb you. Natural Energy is also enough, which is just suitable for him to try out Senjutsu.
He immediately finished eating the rest of the meal, put down his chopsticks, and went to pack his things. He stuffed the scratch paper, carving knife, and blank scroll into his backpack, as if he was about to go out.
Sakura was startled. "Sir, where are you going? It's almost dark!"
"Valley of the End." Rinto zipped up the backpack, "Go and try the absorption of Senjutsu. You won't be back tonight, so there's no need to prepare meals for me."
"Ah? Go at night? How dangerous it is!" Sakura quickly advised, "Valley of the End It's so remote, and there are wild beasts at night. Besides, you've been up for two days. Can't you rest one night first and go again tomorrow?"
"It's okay." Rinto waved his hand, put on his backpack and walked out the door, "I'll just put up a barrier, no delay."
As soon as he finished speaking, he had already opened the courtyard door and walked out. He walked quickly and turned the corner in the blink of an eye. Only Sakura was left standing in the room, looking at the drafts and unfinished meals on the table, and sighed helplessly.
The setting sun dyed the streets of Konoha into a warm golden color. Rinto walked quickly through the village. When he met the ninjas who greeted him on the way, he just nodded without stopping. His mind was filled with the newly drawn fusion framework, and he just wanted to find a quiet place to try the practical effect.
He didn't notice at all that in the shadows on the roadside, there was a Root ninja wearing a mask. He looked at the direction he left and quietly crushed the communication talisman in his hand.
