The day after the six final versions of the medical patches were sent out, Tsunade personally came to the door of the laboratory. She did not come in to disturb Rinto's experiments, but only asked Sakura to take the lead. On the one hand, she solemnly thanked her, and on the other hand, she raised a new demand: Can she design a civilian version of the patch that can be produced without Chakra at all, and can even be industrialized and mass-produced?
Tsunade's concerns are very realistic. Even if Rinto has lowered the threshold for patch production to a very low level, medical ninjas with basic Chakra control abilities are still needed to carve the core Chakra configuration. Konoha The number of medical ninjas is limited. During wartime, they have to be responsible for frontline treatment, treatment of the wounded in rear hospitals, and also have to recruit people to make patches. They are simply too busy, and the production capacity cannot keep up with the massive demand during wartime.
More importantly, once Konoha is attacked, a large number of civilians will be injured, and most of them will not refine Chakra. Even if there are ready-made patches that can be used, if the production capacity of the patches cannot be increased and the reserves are not enough, the critical moment will be It's still to no avail. What she wants is a solution that even civilians who don't know how to Ninjutsu can make it in batches according to the process, and can even produce it in large-scale industrial production like ordinary plasters, completely solving the problem of production capacity and realizing universal reserves.
When Sakura conveyed Tsunade's request to Rinto, he was still a little nervous, fearing that Rinto would find it troublesome and refuse directly. After all, what this gentleman hates the most is this kind of repeated demand that delays his experimental time.
But to her surprise, Rinto was silent for a few seconds, then nodded in agreement, and made only one request. "Give Konoha the dressing materials that are most suitable for mass production, Chakra storage media, all related material samples and parameters were all sent to me. In addition, the mass production process data of Konoha printing factory and charm making workshop were also sent to me."
He agreed not because he cared about Konoha's production capacity, nor because he cared about the lives of civilians, but because the subject itself was of research value to him. How to solidify the structure that required precise Chakra carving. Forming a stable form that can be replicated on a large scale and can be triggered without Chakra is itself an in-depth exploration of Chakra configuration solidification technology. Once completed, it can extend many new research directions.
Sakura was overjoyed, and immediately ran back, sorted out all the material samples and process information that Rinto asked for, and sent them over on the same day. He even gave Konoha the contact information of the top charm makers and printing factory masters, saying that if there were any problems with the process, he could call them over at any time.
Rinto ignored the master craftsman. He first tested and analyzed all the material samples sent one by one, and found out the Chakra conductivity, stability, storage time, cost, and ease of mass production of each material.
The core of the traditional medical patch is to use special talisman paper as the base. The medical ninja carves the Chakra configuration on it, seals it with Chakra, and triggers it when used. This method must be done by people who know Ninjutsu, and it is difficult to mass-produce and the cost is high, so it is not suitable for large-scale storage for civilians.
What Rinto wants to do is to completely overthrow the traditional idea of making symbols and design a pre-cured, Chakra-free solution that can be printed and mass-produced on a large scale. Two core problems need to be solved: first, how to shape the complex Chakra, to create a stable pre-cured template that can be copied on a large scale, without the need to manually carve it every time; secondly, how to make the patch automatically trigger and take effect stably without the user having to inject Chakra at all, and even the production process does not require the participation of medical ninjas.
In response to the first problem, Rinto designed a set of configuration template printing solutions based on the printing process of the Talisman Making Workshop. He disassembled the core configurations of the six patches into array templates that can be standardized and reproduced, and used a special pattern template that can stably carry Chakra ink prints the array patterns directly on the dressing material. There is no need for medical ninjas to engrave them one by one. They only need to make a set of master plates, and the array patterns can be printed in large quantities and quickly just like printing flyers. The efficiency is thousands of times higher than manual engraving, and the cost is also reduced to an extremely low level.
The most critical thing is the ink with the load-bearing configuration. Rinto is based on the existing charm-making ink of Konoha. It has been optimized and improved, adding a trace amount of natural mineral ingredients that can stably store Chakra. points, so that the printed array pattern can maintain the integrity of the configuration stably for a long time and will not fail due to the passage of time or environmental changes. At the same time, the cost is extremely low. The raw materials can be found everywhere in Shinobi World, which can fully meet the needs of large-scale mass production.
In response to the second problem, which is the problem of "no Chakra trigger", Rinto made a two-layer core design.
The first layer is the pre-charging design. He designed a set of micro, stable Chakra storage arrays, integrated with the core functional configuration. After the patch production is completed, only the master plate needs to be charged once, and each printed patch will come with a sufficient amount of sealing power. The stored Chakra does not require the user to inject Chakra at all. Moreover, the sealed Chakra is extremely stable and can be stored for a long time at room temperature without problems of Chakra escaping or failing.
The second layer is a multi-mode automatic trigger design. He designed corresponding automatic trigger mechanisms for different patches: patches for traumatic injuries such as hemostasis, analgesia, and bone setting will automatically trigger the configuration when exposed to blood and body fluids, releasing Chakra to take effect; patches for internal injuries and detoxification will be attached to the skin. When placed on the skin, it can be automatically triggered by the trace bioelectricity of the skin without any additional operations; the mental soothing patch can even be used by children and the elderly who do not understand Ninjutsu at all.
At the same time, he has made extreme simplifications for civilian use scenarios. He has removed all parameter adjustments and mode selections that require professional knowledge, retaining only the most core and most versatile effects, and lowering the threshold for use to the extreme - no matter who it is, no matter whether it is Ninjutsu or not, just tear open the package and stick the patch in the corresponding position, and it will automatically take effect without any other operations. Even the instructions can be written extremely simply.
In order to ensure safety, Rinto has also specially strengthened the safety lock design. The configuration of the patch will only release the corresponding dose of Chakra in preset scenarios, and there will be no problems with Chakra losing control or excessive release. Even if it is used by children or the elderly, there will not be any safety risks.
After the theoretical design and material improvements were completed, Rinto first made a simple printing master in the laboratory, used the improved ink to print the first batch of civilian patch samples, and conducted comprehensive effect verification, stability testing, and triggering mechanism testing.
The test results are perfectly in line with expectations. The printed patch has complete array patterns, stable configuration, and the precharged Chakra is well sealed. There is no difference in effect from the final patch hand-engraved by the medical ninja. The trigger mechanism is extremely sensitive and does not require the injection of Chakra at all. It will take effect automatically. Even civilians who do not have Chakra can easily use it.
More importantly, the mass production efficiency of this solution is extremely high. A set of master plates can print tens of thousands of patches in one day. It only requires a few ordinary workers who can operate printing equipment. It does not take up the time of medical ninjas at all. The production capacity is directly full, which is enough to meet the wartime needs of the entire Konoha, and even the entire Allied Shinobi Forces.
Rinto has compiled the complete plan for the civilian version of the patch, including the improved ink formula, matrix printing master design, pre-charging plan, mass production process, quality control standards, and storage specifications, into a complete document. Even the adjustment parameters of the printing equipment and the master production method are clearly written. Even printing factory workers who do not understand Ninjutsu or the configuration can quickly get started and achieve large-scale mass production by following the plan.
In the afternoon after the plan was compiled, Sakura came over to send the clinical data. Rinto directly handed her the complete mass production plan.
"This is a civilian version that can be mass-produced. There are six models. The effect is the same as the final version. It can be made and used without Chakra." Rinto said in a calm tone, "Give it to Tsunade, whether mass production can be achieved is your business. During the mass production process, let the Talisman Maker and Printing Factory solve problems with materials and processes by themselves, and don't bother me. Only if there are problems with configuration failure and substandard effects, please send us the data and samples."
Sakura was stunned as she held the thick plan. She just conveyed Tsunade's needs yesterday. In just over a day, Rinto not only completed the plan design, but also completed the material improvement and sample verification, and came up with a complete mass production plan that could be implemented directly? This speed was simply beyond her understanding.
"Mr. Rinto, you... you actually finished it so quickly?" Sakura looked at the plan in disbelief. The content inside was extremely detailed. Even the operation process of each step and the ratio of each material were clearly written. There were no technical barriers at all. Once you get it, you can directly mass-produce it.
"Hmm." Rinto didn't say any more, his eyes had already fallen back on the clinical data file she sent, obviously not wanting to talk about this topic anymore.
Sakura quickly put the plan away carefully, not daring to disturb her any more. She just said, "I'll send it to Lady Tsunade right away" and ran out quickly. The shock in her heart was beyond words. Lady Tsunade was originally worried about production capacity, and was even preparing to summon all the medical ninjas that could be mobilized to make patches off-duty. Unexpectedly, Rinto completely solved this problem in one day.
In the Hokage building, Tsunade was also shocked when she got the plan. She flipped through the entire plan, couldn't help but sigh, and said to Shizune beside her, "This Rinto, what a monster. Problems that others cannot solve for several lifetimes are as easy as eating and drinking in his hands. With this plan, Konoha's wartime medical reserves are completely stable."
She immediately ordered to summon everyone from Konoha's charm-making workshop, printing factory, and medicine shop to start large-scale mass production of patches overnight, giving priority to civilians in the village, schools, Police Force, and frontline ninja troops.
The initiator of all this, Rinto, didn't care at all. He even forgot about the mass production plan he had just delivered, and was deducing a more precise nerve repair configuration based on a case of nerve damage repair in the clinical data. To him, the solution that allowed Konoha to be mass-produced was just a small project that could be easily completed. Only these brand-new experimental data that could expand his cognitive boundaries were truly worthy of his investment.
