Medical ninjutsu will not heal injuries too quickly. Even as an advanced medical ninjutsu, it will take at least five minutes to deal with such large-scale scratches (normal medical ninjutsu).

So, during this free time, Yayoi continued to explain, "Medical ninjutsu is to make the body energy in the chakra active through seals, and then allow this activated chakra to flow and release in the body in a specific combination."

According to his own understanding, Soseki said, "Can we explain it like this? Chakra is a known number, escape technique is a formula, and handprints are auxiliary calculation tools. The more powerful the escape technique, the more complex the formulas are. The more handprints we need to be an auxiliary calculation tool, the final result is the ninjutsu we want to release."

This was the first time Yayoi heard such a novel explanation. She subconsciously felt that Soseki was very reasonable, but the ninja's lack of attention to basic teaching made her feel a little inaccurate, "Why do you think this way?"

Soseki said seriously, "I read "Introduction to Chakra", "Ninjutsu", "Essence of Ninjutsu" and many other books in the library today, but it is said that the three keys to using ninjutsu are that there are enough chakra, correct handprints, and complete ninjutsu magic styles."

Meisha and the other two were puzzled, "Is there anything wrong with this?"

"But I heard that the first Hokage who established Konoha could be cured without seals." Soseki said in a deep voice, "In other words, the process of sealing can be omitted, right?"

In Soseki's view, if the handprints are calculation tools, then the first generation was a mental arithmetic master who could directly skip the cumbersome process in the middle.

"It seems that you have noticed the impact of sealing on medical ninjutsu!" Yaya sighed, "Every second we consume during the sealing process may be transferred to the injured as a cost, so every medical ninja must spend a lot of time practicing sealing."

"However, even Master Tsunade cannot do such a thing as healing without seals. Don't think too much, let alone ignore the practice of seals."

Soseki nodded vigorously, "I will."

His eyes are very long-term, but he is not very arrogant. He wants to surpass him without trying to understand. Most people like this can't go far.

Seeing that Soseki was not as paranoid as an ordinary genius, Yayo breathed a sigh of relief, and then continued to explain, "The difficulty of using medical ninjutsu and illusion is much higher than that of ordinary ninjutsu. The reason is that it controls chakra. Generally, ninjutsu only needs to mobilize the chakra in the body through seals, but medical ninjutsu is different. It requires precise control of the part of the body energy in the chakra composition."

Kotoko raised her little hand and asked, "Senior Yayoi, why don't we mobilize our body energy directly when we use medical ninjutsu?"

"You are still a ninja. Have you forgotten the most basic knowledge?" Yayoi replied angrily. "Body energy and mental energy are more of a concept. Only when the two are fused into chakra can they be considered to be truly physical. If you want to achieve the situation you said, unless someone's physical energy can be powerful to the point of substantiality, how can such a thing be possible?"

"Oh." Kotoko shrank her head embarrassedly. She was full of formula tools just now, but for a moment, she didn't even react.

Soseki held his chin with his little hand and pondered, "Overyone uses chakra without attributes and changes in nature. The reason why the immortal art is powerful is because the essence of chakra has changed. Could the root of the power of the first Naruto be related to the essence of chakra?"

...

At night, inside the stone-stone cabin.

Soshishi sat at the table, holding a knife, and carefully drew a shallow scar on the back of his left hand.

Quickly make seals with both hands, and then place the right hand with a light green light on the back of the left hand.

"It's a little itchy and painful. It should be because the granulation tissue is accelerating its growth and the nerve endings are recovering slowly... One minute? Even if it's just a small trauma of this level, one minute is already my limit." Soseki whispered, carefully collecting feedback from his body.

This does not mean that Soseki is so kind. He would rather hurt himself than catch a few small animals for an experiment. He did this just because only his own body can get the most real feedback.

If the experience that can be gained by simply using healing techniques is 1 and the experience that can be gained by experiments is 3, then the feedback experience that Soseki now gets from his body is 10!

This is the best way to improve proficiency when the amount of chakra he can refine in a day is limited.

Moreover, Soseki also needs to figure out how much you tolerate pain and how accurate your recovery time will be when using medical ninjutsu.

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

"Only in this way can I accurately control myself in the battle half a month later... to what extent of injuries I suffered!"

...

In this way, Soseki attended class seriously during the day, soaked in the library at noon, "squeezed" Asma's surplus value after school, harmed himself at home at night, and went to the hospital for internship on weekends.

During this period, although there were occasional small episodes of youthfulness, Soseki easily settled it, and then devoted all his energy to this extremely fulfilling study life.

Soon, half a month flashed by.

Ding Ding Ding--

When the bell rang out on time, a burst of cheers suddenly rang in the classroom, and then almost everyone turned their attention to the two protagonists today.

Since it was a private "confrontation", in order not to occupy public time, Soseki specially agreed to take place after school this day.

"Soseki, you must win!"

"Squad leader, I'm here to see you!"

"Asma...well, nothing, I shouted wrongly."

Everyone around was cheering for the "two people".

Although Asma didn't care much about other people's opinions, she couldn't help feeling sore when she listened.

At this time——"Asma classmate..."

Hearing this sudden sound, Asma was excited. It seemed that he still had supporters!

Looking in the direction of the sound, the girls in the class shouted to him as if they had formed a united front:

"If you dare to beat Soseki, we won't let you go!"

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

"Oh, don't say it anymore. If you continue talking, Asma will cry!"

In fact, they don’t have much malice towards Asma. Since Asma and Soseki became "friends", they have also changed a lot about Asma - how can people who can become friends with Soseki, be bad people?
