The speed at which medical ninjutsu heals injuries is not too fast, and even if it is a high-level advanced medical ninjutsu, it will take at least five minutes to deal with such a large area of scratches (normal medical ninja).

Therefore, during this free time, Yayo continued to explain, "Medical ninjutsu is to make the body energy in the chakra active through sealing, and then let this part of the activated chakra flow and release it in the body in a specific combination. ”

Soseki said according to his own understanding, "Can you explain it like this, chakra is a known number, the escape technique is the formula, and the mudra is an auxiliary calculation tool, the more powerful the escape technique, the more complex the formula, and the more mudra needs to be used as an auxiliary calculation tool, and the final result is the ninjutsu that we want to release." ”

It was the first time for Yayo to hear such a novel explanation, and she subconsciously felt that what Soseki said made sense, but the ninja's lack of attention to basic teaching made her a little uncertain, "Why do you think that?" ”

Soseki said seriously, "I flipped through the "Introduction to Chakra", "Encyclopedia of Ninjutsu", "Essence of Ninjutsu" and many other books in the library today, but they all said that the three keys to using ninjutsu are to have enough chakra, correct mudras, and complete ninjutsu styles. ”

The three of Mei Sha on the side were puzzled, "Is there anything wrong with this?" ”

"But I've heard that the first Hokage who established Konoha can be healed by Muji." Soseki said in a deep voice, "In other words, the process of sealing can be omitted, right?" ”

In Soseki's view, if the mudra is a calculation tool, then the first generation is a master of mental arithmetic, and he can directly skip the cumbersome process in the middle.

"It seems that you have also noticed the effect of the seal on medical ninjutsu!" Yayo sighed lightly, "Every second we consume in the sealing process can be transferred to the injured as a cost, so every medical ninja must spend a lot of time practicing the seal. ”

"However, even Tsunade-sama can't do such a thing as a seal cure, so don't think too much about it, let alone ignore the cultivation of the seal."

Soseki nodded vigorously, "I will." ”

His vision is very long-term, but he is not a master with a low eye, and he wants to surpass without trying to understand, most of this kind of person will not go far.

Seeing that Soseki didn't have the kind of self-paranoia that ordinary geniuses have, Yayo also breathed a sigh of relief, and then went on to explain, "The difficulty of using medical ninjutsu and illusion is much higher than that of ordinary ninjutsu, and the reason is because of the control of chakra. Generally, ninjutsu only needs to mobilize the chakra in the body through sealing, but medical ninjutsu is different in that it needs to precisely control the part of the body energy in the chakra composition. ”

Kotoko raised her small hand and asked, "Yayo-senpai, why don't we directly mobilize our body energy when we use medical ninjutsu?" ”

"You're still a ninja and you've forgotten even the basics?" Yayo replied angrily, "Physical energy and spiritual energy are more of a concept, only when the two are fused into chakra can they really have an entity, if you want to do the kind of situation you said, unless someone's physical energy can be strong enough to materialize, but how is this kind of thing possible?" ”

"Uh-oh." Kotoko shrank her head in disbelief, her mind was full of formula tools just now, and for a while, she didn't even react.

Soseki raised his chin with his small hand and pondered secretly, "Ordinary people use the retreat technique with no attribute chakra plus nature change, and the reason why the immortal art is powerful is because the essence of chakra has changed, so the root of the original Hokage's strength is also related to the essence of chakra?" ”

……

At night, inside a log cabin in Soseki.

Soseki sat at the table, holding a knife, carefully scratching a shallow scar on the back of his left hand.

The hands are quickly sealed, and then, the right hand, which glows with a light green light, is placed on the back of the left hand.

"It's a little itchy and painful, probably because the granulation tissue is growing faster and the nerve endings are recovering more slowly...... A minute? Even if it's just a small trauma of this magnitude, one minute is already my limit. Soseki whispered, carefully collecting feedback from his body.

This is not to say that Soseki is so kind, he would rather hurt himself than catch a few small animals for experiments, he only does this because only his own body can get the most realistic feedback.

If the experience you can gain by using the healing technique alone is 1, and the experience you can gain by experimenting is 3, then the feedback experience that Soseki gets from his body is 10!

With a limited amount of chakra he can refine in a day, this is the best way to improve his proficiency.

In addition, Soseki also needs to figure out how tolerant he is of pain, as well as the precise recovery time when he uses medical ninjutsu.

As a medical ninja, he must ensure that his physical condition is under absolute control at all times.

"Only in this way will I be able to control myself precisely in that battle half a month later...... What extent of the injury! ”

……

In this way, Soseki attends classes during the day, soaks in the library at noon, "squeezes" Asma's surplus value after school, self-harms at home at night, and goes to the hospital for internships on weekends.

During this period, although there are occasionally some youthful episodes, they are easily smoothed out by Soseki, and then all his energy is devoted to this extremely fulfilling study life.

Soon, half a month passed in a flash.

Ding Ding Ding –

When the school bell rang on time, there was a sudden burst of cheers in the classroom, and then, almost unanimous everyone, turned their attention to the two protagonists today.

Since it was a private "duel", in order not to occupy public time, Soseki deliberately agreed to take it after school on this day.

"Soseki, you must win!"

"Squad leader, it's up to you!"

Asma...... Well, nothing, shouted wrong. ”

Everyone around was cheering for the "two".

Although Asma didn't really care about other people's opinions, he couldn't help but feel sour in his heart when he listened.

At this time—"Asma-san......"

Hearing this sudden sound, Asma's spirits perked up, and it seemed that she still had supporters!

Looking in the direction from which the voice came, the girls in the class shouted to him as if they had formed a united front:

"If you dare to win Soseki-san, we won't let you go!"

"You can't say that, Soseki-kun will be angry, but if you dare to let Soseki-kun get hurt...... Hum! ”

"Oh, don't say it, if you keep talking, Asma-san will be crying!"

In fact, they don't have much malice towards Asma, and since Asma and Soseki became "friends", they have changed a lot about Asma - how can someone who can be friends with Soseki-kun be a bad person?

Of course, the warnings are also true!
