Healing Injuries

Konoha Cemetery.

Haku sat before Might Duy's grave. So much had happened the day he returned to the village; he needed quiet to think. He also needed to see what the System could bring him now that it had awakened.

When he woke up from his coma on the front lines, he had noticed the System was awakening, but it still hadn't woken up. There was no countdown, and he didn't know when it would.

Old man, you and Duy were implicated because of me. I wonder if anyone else was involved besides Danzo.

Teacher Orochimaru has already started investigating. I believe there will be results soon.

It's just that I'm a little worried about Duy's safety now. He's been assigned to the front lines on a mission.

Haku said a lot before Might Duy's grave. Haku wasn't sure if Duy, in the Pure Land, could hear him. But now, Haku had cut almost all his ties in the ninja world. He didn't know if that was good or bad.

Might Duy was far away on the front lines. Haku was worried he might encounter danger, so after leaving the cemetery, he went to find Orochimaru. After asking Orochimaru to look after Might Duy, he came alone to Konoha Hospital.

Because of his excellent medical ninjutsu skills, his position at Konoha Hospital had been retained. During his recovery period in the village, Haku planned to spend his time at the hospital.

Sitting in his own office, Haku took out the ninjutsu scroll Orochimaru had obtained from Tsunade.

Creation Rebirth Jutsu: Release the jutsu, stimulate cells by consuming chakra, and rapidly divide them in a short period to heal injuries. This jutsu can only be used on oneself and requires a large amount of chakra. If chakra is insufficient, it will consume the user's life force. Use with caution.

Note 1: The amount of chakra consumed each time Creation Rebirth Jutsu is activated is equivalent to the chakra of a normal Jonin, or the entire life force of a normal adult male.

Note 2: To complement the use of Creation Rebirth Jutsu, the Yin Seal Jutsu was created.

Seeing the introduction to Creation Rebirth Jutsu, Haku understood why such a useful healing ninjutsu was no longer used in the original Naruto World.

This wasn't healing ninjutsu at all; it was practically a suicide jutsu. Injuries requiring treatment usually occurred after battles, when chakra was already depleted to a certain extent. Where would there be enough chakra left to use this jutsu?

Even though a ninja's life force was stronger than an ordinary person's, it couldn't withstand such depletion.

No wonder only Tsunade could use this jutsu.

After reading about Creation Rebirth Jutsu, Haku knew that it wasn't something he could learn and practice in his current state. He set it aside and picked up another scroll.

Yin Seal Jutsu: Carve a sealing formula on the forehead to form a space within the body capable of storing chakra. Normally, it stores refined chakra at a certain ratio until the chakra is full, forming a chakra gem on the forehead.

Once the chakra is full, the Yin Seal is in an activatable state. Upon activation, it provides a large amount of chakra to support the release of various ninjutsu.

Note 1: The Yin Seal was modified based on female physiology and is only applicable to female ninja. Other users should modify it according to their own physical conditions.

Note 2: The Yin Seal Jutsu merely stores unused chakra; it does not increase or alter a ninja's chakra refinement speed or total chakra. However, it will temporarily reduce chakra output when not fully charged.

Note 3: This jutsu is a variation of the Uzumaki clan's ninjutsu. Cultivation requires prior mastery of a large number of sealing jutsu as support for this technique.

Sigh! It looks like I still need to train in sealing jutsu! I'll see if I can ask Kushina for guidance then. Minato Namikaze should be reliable, right?

After reading the Yin Seal scroll, Haku sighed, lamenting that the things he needed to cultivate had increased again. At the same time, he thought of the fiery-haired, hot-tempered girl, hoping Minato could handle her.

He glanced at the scrolls related to sealing jutsu placed on the other side but didn't rush to read them. His body hadn't fully recovered yet, so healing was the priority.

Then, he began to apply medical ninjutsu to himself.

And so, Haku's life in the hospital began once more.

He worked at the hospital during the day, treated himself, and studied the basics of sealing jutsu. He trained simply at night. Because Minato Namikaze had not returned from the Iwagakure front lines recently, Haku's plan to learn sealing jutsu from Kushina Uzumaki had not yet been realized.

Thus, a month passed.

Mmm, the hidden injuries in my body are finally healed. With my current strength, I can no longer detect any injuries in my body.
