The finalized barrier, news from Mount Myōboku, and a new challenge in the medicinal fields

The early morning dew was still hanging on the grass blades in the corner of the courtyard, and Rinto had already finalized the optimization plan for protecting the village boundary.

The foundation of the barrier left by Second Hokage was already solid, but it was just tinkered with over the decades and redundant seals were piled up layer by layer. Chakra's circulation path had long been crooked. He did not touch the core defense logic and only deleted nearly 70% of the useless redundant nodes. The supply chain of Chakra has been reorganized, and a three-layer adaptive configuration has been embedded - it can automatically adjust the focus of defense and the distribution of Chakra according to the intensity of external attacks, which not only saves the consumption of daily maintenance, but also fills in the loopholes that are easy to be penetrated.

He drew four complete drawings, ranging from the frame adjustment of the entire barrier to the modification of the parameters of each node, and even the construction steps and remedies for errors were clearly written. He put down the pen and folded the drawings. Just as he was about to reach for the water glass on the table, he heard rustling noises coming from outside the courtyard door. Someone was lingering at the door, but he did not dare to knock on the door.

"Come in, the door is unlocked." Rinto frowned and shouted.

The door was immediately pushed open gently, and the squad leader of Barrier Team walked in quickly with two young ninjas, carrying a gift box in his hand, with a flattering smile on his face, "Mr. Rinto, we didn't dare to disturb you, we were waiting at the door until you were done with your work before we dared to say anything."

"The plan is ready." Rinto pushed the stacked drawings over, "Follow the above steps and change it. First try the boundary section in the northwest corner. If there is no problem, then replace it in full. Don't change the parameters of the nodes. I will not be responsible if it breaks."

The squad leader quickly took the drawing with both hands and opened it carefully. After just one glance, his eyes straightened. He had been working on the barrier for more than ten years, and he could see the subtlety of this plan at a glance - the originally messy nodes were clearly sorted out. The emergency reinforcement that originally required four Jonin now only needs one Chunin to control it, and the consumption of Chakra has been reduced even more than they expected.

"Thank you so much! Mr. Rinto!" The squad leader's voice trembled with excitement, "You solved the problem that we had been struggling with for several months without solving it in three days! You really helped us a lot!"

The two young ninjas behind him also bowed repeatedly, with admiration in their eyes. Their hair was almost turning white when they were looking at the old boundary drawings, and they couldn't get it right no matter how they changed it. Unexpectedly, Rinto solved all the problems with a few random drawings.

"Don't thank me." Rinto waved his hand and said calmly, "After changing the boundary, just don't come to me again, and don't disturb my research with trivial matters."

"Absolutely not! Absolutely not!" the squad leader quickly assured, putting the gift box in his hand on the table, "This is just a little bit of our thoughts. They are some worthless tea and snacks. They can help you stay up late. We won't disturb you anymore. We will go back and change the barrier. If there is a problem, we... we will try our best to solve it ourselves. If it doesn't work, I won't trouble you again!"

The three people retreated quietly, being extremely careful when closing the door for fear of making any noise. Rinto glanced at the gift box, but did not move. He turned around and picked up the Senjutsu practice record that Jiraiya had sent before, and started flipping through it again.

He had just finished reading the record yesterday. He still had a few details that he hadn't figured out yet. He was holding a pen and deducing on the draft paper when footsteps came again outside the courtyard door. This time it was Kakashi. Before anyone came in, he knocked on the door first. "Mr. Rinto, is it easy to come in?"

"Come in."

Kakashi opened the door and came in, holding a scroll and a small bag of three-color meatballs in his hand, with his usual lazy smile on his face, "I'm not disturbing your work, right? I just came back from a mission at the border Land of Fire, and I brought you something along the way."

He put the scroll on the table. "Lord Jiraiya just came back from Mount Myōboku, Naruto Senjutsu's new record of practice, and Natural Energy's balance details added by Sage Fukasaku. He specifically said that you will definitely need it."

Rinto's eyes lit up, and he immediately reached for the scroll and opened it. Not only did it contain Naruto's latest training data, but also Mount Myōboku written by Sage Fukasaku The core logic of Senjutsu, and even the concentration differences and absorption precautions of Natural Energy in different environments, are all written clearly and in more detail than the previous handbook.

He was so focused on reading that he didn't even pay much attention to what Kakashi said, until Kakashi added with a smile, "Naruto, that boy, he has been stumbling in practice, and he absorbed yesterday. Natural Energy didn't control himself well, and half of his face turned into Toad's face. He was scolded by Sage Fukasaku, and he lost his temper and said he didn't want to practice anymore. Then he turned around and went to fuck Toad Oil again."

"Chakra's control accuracy is too poor, it's weird if it doesn't roll over." Rinto complained casually without raising his head. His fingertips stopped at the page where the balance was out of control, and he picked up a pen and wrote down two strokes on his scratch pad, "He can't even control the balance of his own Chakra, let alone add Natural Energy."

Kakashi smiled and was not surprised. This gentleman's attention was always only on these data and logic. As for what joke Naruto made, he was not interested at all. He leaned on the table and added casually, "Speaking of which, The Chakra path you changed for me before is really useful. I used Kamui three times in a row for this mission, and my eyes didn't hurt much. The consumption of Chakra was also reduced by more than half, which I didn't even dare to think about before."

This sentence finally made Rinto raise his head and ask, "When using Kamui, are there any abnormalities in the Chakra circulation around the eyes? Are the nodes offset?"

"No, it's very smooth." Kakashi nodded, "Before, every time I used it, my meridians would hurt for a long time, but now I don't have any problems at all. Even Lady Tsunade was surprised, saying that the old injury to my eyes could be healed so completely."

Rinto said "hmm", lowered his head and added two lines of notes on the previous Sharingan inspection record, and then returned his attention to the Senjutsu scroll. Kakashi Seeing that he was immersed in it again, he didn't bother him any more. He put the three-color meatballs on the table and walked gently Earth Flow. When he left, he didn't forget to help him hold the ajar door.

It wasn't until noon that Sakura came in with a thermos bucket, and saw Rinto still maintaining the same posture as in the morning, sitting at the table and turning the scroll. The breakfast on the table had not been touched at all, and it had already become cold.

"Sir, you haven't had breakfast." Sakura sighed helplessly, put away the cold breakfast, and put the lunch he just brought on the table, "I brought you pork bone rice and vegetable soup. Eat it while it's hot. If you continue like this, you will have stomach problems."

Rinto put down the scroll, rubbed his sore eyes, picked up the chopsticks, and asked casually, "Is there anything going on at the hospital today?"

"It's true." Sakura pulled up a chair and sat down, his tone was a little helpless, "Yesterday, three Chunin were sent back from the border. During the mission, they were hit by the traitorous Genjutsu. After being rescued, they have been mentally unstable, and sometimes I have headaches and hallucinations all the time. Conventional Medical Ninjutsu is of no use at all. Even Lady Tsunade can only temporarily stabilize it and cannot be cured. The teachers are saying that you were studying Yin Release and the repair of mental damage. I want to ask if you have any solution."

Rinto paused with his chopsticks, and his eyes became more interested. He has been thinking about Yin Release's mental configuration these days. The theoretical framework has been set up, but there are not enough cases of mental injury to verify, so it just happened to be delivered to his door.

"After dinner, take me to the hospital for a checkup." He said immediately, picking up the rice much faster.

Sakura was stunned for a moment, then smiled, "Okay! I knew you would be interested! I have brought all their cases, can I show them to you first?"

"No, just look at the patient." Rinto shook his head. No matter how complete the case data on the paper is, it is not as intuitive as the directly detected mental energy damage. "I want to see how the mental damage caused by Genjutsu affects Chakra's circulation and nerves."

After dinner, Rinto followed Sakura to Konoha Hospital. The three injured Chunin lived in a separate ward. Their mental state was very poor. They had headaches and rolled around with their heads in their hands. Even sedatives were not used. Rinto was not in a hurry to give treatment. The plan is to first condense extremely fine Yin Release Chakra with your fingertips, then probe into their spiritual level little by little, and figure out the remaining damage locations of Genjutsu, the fracture nodes of spiritual energy, and even the Yin Release logic of the Genjutsu used by the rebels.

He didn't speak the whole time, his brows sometimes furrowed and sometimes loosened. He held the notebook handed over by Sakura in his hand. He made two notes from time to time. After checking the conditions of the three patients, he gave Sakura a message in the corridor outside the ward. drew a repair configuration. "Follow this, use Yin Release Chakra to guide, first clear away the remaining Genjutsu fragments, and then repair the broken mental node, it will be cured in three days."

Sakura took the drawing and looked at the configuration above. His eyes opened wider and wider. "So this is how mental damage is repaired... I always thought about using Yang Release to repair nerves before, but I never found the root cause."

"Their injuries are not physical, but the structure of mental energy has collapsed. Yang Release is useless." Rinto said casually, his eyes still falling on the record book in his hand. His mind was filled with the logic of the damage to the mental level that Genjutsu had just detected. "Please compile a copy of the detailed data of the case and give it to me later."

"Okay! No problem!" Sakura nodded quickly, looking at his mind full of research, he couldn't help but laugh, "Sir, would you like to stop by the emergency room and have a look? There are a few patients who were slightly injured because of Genjutsu. If you are free, you can take a look and collect more data."

Rinto did not refuse, and followed Sakura around the hospital for an afternoon, reading all the cases related to mental injury, taking several pages of notes, and suddenly figured out a few details about the mental repair patch that had been stuck before.

When I returned to the laboratory, it was already evening. As soon as I walked to the entrance of the hospital, I saw Shikamaru squatting under a tree on the roadside, holding a small book in his hand, looking bored. When I saw him coming back, I immediately stood up. "Mr. Rinto, you are back, I have been waiting here for almost an hour."

"Is something wrong?" Rinto opened the courtyard door and motioned for him to come in.

"It's not an urgent matter." Shikamaru followed him into the house and scratched his head, "My dad asked me to ask you whether the method you used to improve wheat seeds can be used for medicinal materials? In our Nara Clan medicinal fields, there are several medicinal materials whose growth cycles are too long and the content of active ingredients is unstable. I would like to ask you if you can use a similar Yang Release configuration to improve the seeds?"

He said, handing over the notebook in his hand. "I have written down the growth cycles and characteristics of several commonly used medicinal materials, as well as the problems we encountered. If it is too troublesome, forget it, it is not an urgent matter."

Rinto took the book and flipped it over, his interest rising again. He had only improved wheat seeds before, and the cell structure of food crops was simple, while the cells of medicinal plants were more complex, and the synthesis of active ingredients involved more precise regulation of cell activity, which just expanded his knowledge of Yang Release's application of plant cells.

"Okay." He nodded, "Where is your medicinal field? I'll go over there tomorrow and have a look. I need to check the growth of the plants and the soil environment before I can determine how to change it."

Shikamaru was stunned for a moment, obviously not expecting him to agree so simply, and then smiled, "Great! It's just outside Konoha. I'll pick you up tomorrow morning?"

"Yeah." Rinto responded, put the notebook on the table, turned it over again, and completely forgot about Shikamaru next to it.

Shikamaru looked at him like this, smiled helplessly, and without interrupting him any more, said, "Then I won't delay you, I'll come back tomorrow morning" and quietly left.

Not long after Shikamaru left, Tsunade opened the door and came in, holding a wine gourd in his hand and with a smile on his face, "I heard that you showed off your talents in the hospital today. You solved several mental injuries that even gave me a headache?"

"I'm just recording data and giving you a plan." Rinto responded casually without raising his head.

"Okay, you kid, now half of Medical Ninjutsu's country is almost taken over by you." Tsunade smiled and sat at the table, taking a sip of wine, "Let me tell you something, Barrier Team has already changed it according to your plan. I tried the barrier in the northwest corner and found that the daily Chakra consumption was directly reduced by 50%, and the reverse osmosis ability was also much stronger. Barrier Team and that group of people, now Tenten talk about you and almost make you a god."

Rinto said "Oh" and had no reaction. He changed the barrier to get rid of it once and for all, so that if the barrier was broken, someone would break in and blow up the village, disturbing his research. As for what other people said, he didn't care at all.

Tsunade has long been used to his reaction, and is not annoyed. He added, "There are two more things. One is that Sunagakure used the wheat seeds you gave them, and the feedback was very good. They said that the drought tolerance is much better than their local seeds. I sent you the planting data, and a bunch of Land of Wind's specialties. I asked Shizune to put them in your mailbox."

"Second, Akatsuki has been making more and more moves recently, and has arrested Four-Tails of Iwagakure. Five Great Shinobi Villages plans to hold a joint meeting later to discuss jointly dealing with Akatsuki. It will be held in Land of Fire's Daming Mansion. Do you want to go?"

Rinto refused without thinking, "I won't go. Too many people will make noise and waste time. As long as they don't come Konoha to blow up the village, don't look for me."

"I knew you would say that." Tsunade laughed, "I have already rejected it for you, saying that you are busy with research and have no time. But having said that, Akatsuki is getting more and more crazy now. You should pay attention when you go out. I have asked Anbu to set up a post around you, and no idlers will come here."

"Yes." Rinto nodded, thanking him.

Tsunade didn't bother her much, took two sips of wine and left. She knew that staying for one more minute would be disturbing Rinto's research.

It was completely dark. Rinto lit up the oil lamp in the room. He first sorted out the mental injury cases recorded in the hospital in the afternoon. Following the injury logic of Genjutsu that he touched today, he changed the configuration of the previous mental repair patch. It is more stable and has a wider range of applications than the previous version.

After finishing this, he flipped through the medicinal material information left by Shikamaru. Looking at the medicinal material growth characteristics recorded by the Nara Clan, he drew a preliminary Yang Release configuration idea on the paper. He stopped from time to time to check the previous wheat seed improvement records and compare the differences in plant cells.

The moon outside the window rose very high, and the streets of Konoha had long since become quiet, with only the occasional footsteps of patrolling ninjas passing by. The oil lamp in the laboratory was still on, and the rustling of the pen tip across the paper was particularly clear in the quiet night.

Rinto completely forgot about time and dinner, and only saw the formulas and configurations on paper. For him, such a quiet day where he can do research without being disturbed is better than anything else.
