"Unlike simply changing the breathing to adjust the state, the so-called full-concentration breathing is to inhale a large amount of oxygen into the lungs, allowing more air to enter the blood, thereby accelerating the blood flow and the heartbeat. In this way, the body temperature will rise. When the body temperature rises and the blood becomes hot, humans can temporarily have a body as powerful as a ghost." Yuzhongjin explained the most fundamental principle of the breathing method to Hudie Kanae and Hudie Shinobu, and finally added: "Therefore, this law has the side effect of damaging the functions of internal organs, and in order to offset this cost, another 'cultivation method' is needed." The breathing method of the Yamabushi sorcerer is similar to the breathing method of the Demon Slayer Corps, but has a very different structure. The two complement each other. The breathing method is suitable for quick success, while the qigong method can consolidate the foundation. "Ask a question!" Hu Die Ren raised her hand. "explain." Yuzhongjin signaled Hu Die Ren to speak. "Why don't we just learn Qigong?" Since Qigong had no side effects and had similar effects to breathing techniques, Hu Die Ren felt that practicing only one was enough.
"Because at this stage you don't have the leisure time to retreat for more than ten or twenty years." The learning process of Qigong is very slow. Even if one has great talent, one may not be able to master it even if one learns from the age of eight to twenty-five. Yu Zhuanjin has many considerations for this. Taking into account the "Pillar"-level combat power of "Demon Slayer", the number is particularly insufficient at the current stage. The veteran "Pillars" have declined in combat power after middle age due to their practice of breathing techniques. For example, the then Flame Pillar and Water Pillar were both hesitating between resigning and retiring or retreating to the second line. If the new generation were to continue to practice the Qi training method provided by Yu Zhuanjin in a collective and chronic manner, the gap that would be created in the middle would pose a huge hidden danger. Therefore, it can only be arranged in parallel in two lines. "Xiao Shinobu, listen carefully to Master. Master must have thought of the problems you can think of." Hu Die Kanae asked Hu Die to be more obedient. "Yes~" Hu Die Shinobu never talked back to Hu Die Kanae. "Breathing with full concentration, in this state, allows the power generated in your body to take shape. Water is the softest among them, just like..." Yuzhongjin picked up the wooden sword and released the form. Water Breathing: Three Forms, Flowing Dance! When this move was released, Yu Zhuanjin's figure disappeared in an instant, and was replaced by a raging wave that looked like water flowing into a roll. High-speed movement combined with the skill of afterimage combines attack and dodge together, which is equivalent to fast and multi-directional output in different directions. After using this move, Yuzhongjin threw down the wooden sword. She is not good at using close-range weapons, so this skill is not as smooth as using bare hands. "Oh~" Hu Die Ren clapped her hands immediately upon seeing this. Praising Yuzhongjin's performance.
"Calm down!" Hu Die Kanae finally couldn't hold it in any longer and pressed down on Hu Die Shinobu's head. "In order to release the 'form', your breathing must remain fully focused, so today you don't need to practice swinging your swords. Maintain the basic operation of the breathing method and go on patrol with me." Yu Zhuanjin gave a seemingly simple training goal, but in fact, it was far more difficult than swinging the sword a thousand times. There is a natural pattern in human breathing, which is a habit maintained since birth. This breathing method is an abnormal breathing. It is fine if it is only used temporarily, but if it is maintained continuously, it will make those who are not familiar with it feel uncomfortable. "Make 'abnormal' your new 'normal'." Yu Zhuanjin took out a three-foot-long feather duster and gently spanked Hu Die on the butt. Don't think that she doesn't know she is being lazy because she is holding her breath. This is a necessary process of practice. Not only breathing methods, but even ordinary Qigong methods require practitioners to continuously change the breath in their bodies. Hu Die Shinobu covered her butt and hid behind Hu Die Kanae. Really, she has a completely different personality from her sister. “But it’s really difficult.” Hu Die pursed her lips. "You'll get used to it. Shinobu can do it." Hu Die Kanae gave encouragement, but within half a second, she was spanked on the butt by Yuzhongjin's feather duster: "Ah~" "Please regulate your breathing while you speak." Yuzhongjin said with narrowed eyes and smiled. He was clearly smiling, why did he look even more ferocious? 【Kanae Hudie and Shinobu Hudie are afraid of the limited 】 …… "Mister Miko." Ubuyashiki Amane always conveys the words of her husband, Ubuyashiki Yoya, the head of the Demon Slayer Corps, to Ootenzu on behalf of her husband. "lady." As both women, they naturally get along well. Yu Zhongjin asked, "Is there anything I can help you with?" "No, I just came to ask if Kanae and Shinobu need a Nichirin sword? One of the forgers from the swordsmith village happened to come to the headquarters and brought some 'Taramatsu'." Ubuyashiki Amane explained the situation. The so-called Tamara is a mineral that absorbs sunlight, and it is used to forge the Nichirin sword that slays demons. However, due to the peculiarity of this mineral, which is very different from ordinary steel, only the blacksmiths in the swordsmith village who have studied it can use it to forge good swords. "...They haven't reached the official stage yet. Isn't this a bit presumptuous?" Yuzhong remembered that only the official members of the Demon Slayer Corps who passed the final selection were qualified to obtain their own Tamagotchi.
"If he is a 'stepson', wouldn't it be easy for him to pass the final selection? It's just a matter of time." Ubuyashiki Amane told Yuzenjin not to worry about it, as rules are sometimes meant to be broken. For example, the latter skipped the selection and was directly promoted to "Pillar". The rules were not defined in this way, although they did not deny it either. "In that case, I will accompany them there later." Hearing this, Yuzhongjin nodded slightly, and then found Hudie Kanae and Hudie Shinobu who were still practicing breathing and energy training, and told them about the two of them forging swords. "Can we have our own Nichirin sword too?" Hu Dieren immediately became impatient. "Of course. Your performance in recent days has caused the boss to relax the rules. Having said that, in my eyes, you are still third-rate." Yuzhongjin didn't think she was strict. Even though she had taught Tsubaki before, the concepts they taught were not the same. It doesn't matter if Tsubaki is not good at learning, the Yamabushi sorcerer on the human side of "Inuyasha" is a very powerful one. But the demon hunters in Demon Slayer... If the sky falls, no one can hold it up. "At least we are in the mainstream." Hudie Kanae said to Hudie Shinobu optimistically. Third-rate is better than nothing. When we arrived at the living room, the blacksmith from the Swordsmith Village and the head of the Demon Slayer Corps, Yoshiya, were sitting opposite each other, apparently discussing important matters. "Oh~ This is the shrine maiden you were talking about." The blacksmith from the Swordsmith Village rushed forward. As the figure got closer, Yuzhong Jin couldn't help but lower his eyes. He had a fancy and weird mask on his face, and he was a little short... Hudie Kanae and Hudie Shinobu poked their heads out from behind Yuzenjin and watched carefully. When they saw the blacksmith from the Swordsmith Village, they opened their mouths in surprise. He is even shorter than the child Hudie Shinobu. Generally speaking, shouldn't a blacksmith be a muscular man with bulging muscles? "Let me introduce you. This is the chief of the swordsmith village, Tetsujin Kawahara." Ubuyashiki Yoya said. "You're the one who invented the... um, technique that can kill demons without using the Nichirin sword?" Tiediheyuan Tiezhen lived at the bottom and looked up at the high ground and asked. "..." Yuzhong Jin didn't know how to answer. Could it be that the training method she provided affected the main work of the swordsmith village?
"Hahaha, that's great. Thank you so much for your generosity, Miss Miko. Now our swordsmith village doesn't have to be so stubborn about forging swords with this material." But Tiechiheyuan Tiezhen laughed and said. "I forgot to tell you that the Swordsmith Village also has a long history. It is a village that was derived from the Muramasa family who forged the 'Muramasa'." Ubuyashiki Yoya said. "By the way, what kind of material do your two 'stepsons' want their knives to be made of?" Tetsuchi Kawara Tetsujin asked. "Yu Gang will do. They are not yet at the level where they can kill ghosts with 'Chi' alone." Yuzhongjin can just ask Tetsuchi Kawara Tetsujin to forge it like an ordinary Nichirin sword. "That's it." Tetsujin Tetsujikawahara took out a bag containing a pile of raw corundum and asked Hudie Kanae and Hudie Shinobu to choose from them. Good weight! As soon as Hu Die Kanae picked up a piece of jade, she felt its huge weight. It was just a piece of jade, but it was so heavy. How did the other party carry so many raw stones? After all, he is a blacksmith from the Swordsmith Village. Appearance should not be judged by appearance. Yuzhong Jin can feel that the strength in Tiechi Kawara Tetsujin's body is not much worse than that of an ordinary A-class soldier. Picking up a piece of raw jadeite, Yu Zhuanjin was also curious about it. What exactly is this mineral that absorbs sunlight? "Do you also want a Sun Blade, Miko? If so, I can do it myself." Tetsuji Kawahara Tetsujin rolled up his sleeves and got ready to work. "Ah, no, how should I put it, is it okay for me to take a piece of jade?" Yu Zhuanjin asked. "Of course it is possible." Although Tiediheyuan Tiezhen was puzzled, he nodded anyway. …… Sunlight is the biggest enemy of ghosts, but weak moonlight or light reflected from the moon cannot harm ghosts. So what ghosts are really afraid of is strong sunlight. In other words, the sunlight absorbed by jadeite also reaches a strong level. Absorb the sunlight and use it in the dark... The corners of Yuzhuanjin's mouth curled up slightly. If it were her, it wouldn't be impossible. Start drawing the talisman, wait until noon, stand under the sun, take out the finished talisman, and use divine power to guide the talisman to absorb sunlight.
——Sun Talisman! When the power of this talisman is unfolded, blazing sunlight will be emitted in an instant, which will last for about a few seconds. Once the power of the talisman is exhausted, it will be completely destroyed. As well as the sealing time of the talisman, even if it is never used, the energy will diffuse outwards. Ten days or half a month may not be a problem, but after two or three months it will need to absorb sunlight again. Hmm~ It seems acceptable. With this method, there is no need to be afraid even when facing an upper-rank demon. Although she has the SSR-level Yuzhuanjin experience card, she doesn't have to worry. The production of talismans requires a foundation of mana, and the total amount of mana needs to be accumulated over time. Ootenzu provided this technology to the Demon Slayer Corps.
