It didn't take Kaiji more than half an hour to gather all the desired scrolls.
Due to yesterday's incident which involving Ichibi's appearance, no missions had been given yet today, and citizens still displayed mixed reactions of confusion and fear.
Even after the village had issued information regarding the incident, one day wasn't enough to settle down the fear of the villagers, despite the fact that Ichibi was taken care of within a few minutes before it could wreak any havoc upon the village.
The only casualties reported currently were five shinobi dead, with no civilians or other ninja harmed.
Casualties were obvious when a Bijuu appeared within the village, despite the number being very low.
Kaiji thought that definitely one of these five shinobi was the previous Jinchūriki of Shukaku.
That was only speculation as he didn't know, and he didn't dwell on it much anymore.
Currently, it was still midday; the sun was high in the sky.
Now that he had the scrolls of Jutsu he needed to learn, he decided to start with Chakra Scalpel.
He thought to just start it now, without wasting any more time.
Even without this, he had a lot of free time today.
Ren had his own team squad, so Kaiji couldn't go to him.
While Hiroshi had gone to bother Kohaku with Ren, to spend some time with her, using yesterday's event as an excuse.
With all this free time Kaiji had, what else could he even do aside from training?
So here he sat on a less-frequented training field of the village.
"Alright, let's see how Chakra Scalpel Jutsu can be performed," he said, unrolling the scroll.
It stated that Chakra Scalpel (Chakra no Mesu) is a medical ninjutsu where the user forms a blade of chakra around their hands.
It isn't typically used for healing in the sense of regeneration or direct healing, but for surgical operations as its primary use.
This can manipulate organs and tissues without needing a physical scalpel, minimizing trauma and infection risk.
"Hmm, why would I need it for surgery? I need it only for self-healing," Kaiji complained upon reading the scroll.
Akane had told him about only those Jutsu which could be used for self-healing, but Chakra Scalpel didn't seem like one.
"Maybe it can be used in that way. Let's read ahead first," he said, deciding to read the instructions further.
After reading some more, he found that it could be used for self-healing in a few ways as well.
One was for internal extraction, where he could use Chakra Scalpel to painlessly remove deeply embedded splinters and solidified poison inside his body to avoid external incisions.
Second was for blockage removal, where he could use it to gently clear minor obstructions or knots within his chakra network, improving flow and accelerating natural recovery.
But for this, he needed a better understanding of his own chakra pathways.
The last was chakra delivery, where he could deliver a very concentrated burst of healing chakra to a tiny, specific internal point.
Like a damaged nerve ending or a special blood vessel for highly targeted repair.
"But there was nothing written about it's offensive use, that was the another reason I choose it," Kaiji questioned, upon reading the context of the scroll.
He remembered that Kabuto Yakushi could use it in combat, by forming the chakra blade on his hand or fingers.
Kabuto could use it by touch on an opponent to sever muscles, tendons, or blood vessels without leaving a visible external wound.
This incapacitated opponents by crippling their movement or cutting off blood supply, without necessarily killing them if not aimed at vital organs.
"Maybe they didn't have it in this scroll, but on some other," Kaiji thought, then focused on the learning process of Chakra Scalpel Jutsu.
It had a simple Three-step process.
If one had good chakra control, they could use it in practice without much problem.
One was Chakra concentration for shaping and molding of Chakra Scalpel.
For this, he had to intensely concentrate his chakra to a single point, either a fingertip or palm.
Then practice shaping this concentrated chakra into an extremely thin, blade-like edge.
Second was stability and sharpness, to improve its holding form.
Once he could roughly shape the chakra, the next step was to maintain its form and sharpness perfectly, without it flickering or dissipating.
He needed to practice passing his "chakra blade" through water without disturbing the surface, or trying to slice a single strand of hair without moving it.
The last was precision application to control its cutting.
He would practice making very precise, imaginary cuts on non-living objects.
Focusing on the intent of the cut rather than actual damage.
"Let's try then~!"
After reading the whole process, he decided to practice it immediately.
Even though he had already paused his Rasengan training, his chakra control was already quite good.
For the next few hours, he tried to concentrate his chakra on his fingertips first.
Early attempts resulted in fuzzy, unstable, and blunt chakra shapes.
But after continuous practice of hours, he was able to guide its form from unstable to a little stable.
"It might takes some time, atleast two week or three to completely learn it," he said, calculating the approximate time needed.
"Looks like I needs to give it a proper dedicated time for learning this, to be able to use is early."
The main reason he chose these two healing ninjutsu, Chakra Scalpel and Blood Coagulation Technique, was because they were simpler and easier than the other two healing ninjutsu.
And they were enough for basic self-healing, if he were to injure himself during training of Seven Heavens Breathing Method.
While there was no immediate risk if he were to start practicing breathing activations, there could be risks as that entire process was going to be experimental, and he didn't want to waste his already limited time wasting in a hospital.
So it was better to have a small first aid kit for himself with him.
The main risk might be internal damage rather than external during activations of Seven Heavens Breathing Activations.
At that time, if he were to be injured, Chakra Scalpel would be more helpful.
Next, he unrolled the scroll of Blood Coagulation Technique.
It stated that this technique is a fundamental medical ninjutsu used to stop bleeding, both internally and externally.
It is often used as an immediate first-aid measure on the battlefield by applying it to open wounds to quickly halt bleeding to stop excessive blood loss.
This also allows the patient to remain conscious, continue fighting for a short period, or be safely moved for more extensive treatment.
Prevention of excessive blood loss makes it easier for medical ninja to then apply more complex healing jutsu or perform surgical procedures.
"This can also be used for internal bleeding control huh, then this can also be helpful in my training."
Kaiji smiled, upon seeing that both basic healing jutsu were quite helpful for his training of Seven Heavens Breathing Activations, which he would start tomorrow.
