Not long after the war began, the pressure on Konoha's side increased significantly.
Before long, even the students in the Ninja Academy were conscripted and sent to the battlefield together.
By this time, even as a Medical Ninja in the Konoha Hospital, Minamikawa Yuu could not remain unaffected.
He accepted the conscription and headed to the front lines of the battlefield.
He wasn't particularly surprised by this situation; he had expected it long ago.
The risks were generally controllable.
After all, even when going to the front lines, as long as he was medical personnel, he would basically stay within the camp and wouldn't have to go out to fight and kill enemies.
There was still sufficient guarantee of safety.
While not completely safe, it was much better than those ordinary Ninjas.
The day before he left, Minamikawa Yuu made a special trip to the Orphanage to say goodbye to Yakushi Nonou.
Unfortunately, within the spacious Orphanage, Yakushi Nonou's figure did not appear, and there was no telling where she had gone.
At this result, Minamikawa Yuu was disappointed at first, but then he felt relieved.
The war between the nations was growing more intense; in this situation, as an Anbu elite, Yakushi Nonou would naturally not be idle, and her missions were likely quite heavy.
Furthermore, within the Anbu, that Elder Danzo known as the Darkness of Konoha was likely keeping an eye on her at this moment.
Since Yakushi Nonou was missing, Minamikawa Yuu gave up on his intent and chose to leave.
The next day, he rushed to the front lines of the battlefield between the Land of Fire and the Land of Earth, becoming a field doctor.
"Are you Minamikawa Yuu?"
Inside the field medical department, a middle-aged man in a white robe looked at Minamikawa Yuu with a serious expression, deeply skeptical of Minamikawa Yuu's level of skill.
This wasn't discrimination, but simply a matter of age.
Even with his age increasing, the eight-year-old Minamikawa Yuu did not look very reliable on the surface.
Even though there were many young geniuses in the Ninja World, such problems were inevitable.
"Yes, I am Minamikawa Yuu."
Facing the man's suspicion, Minamikawa Yuu just smiled, maintaining a polite and gentle appearance from beginning to end: "Is there anything you need me to do?"
"Come with me first."
The man in front of him sighed: "The tasks here are very heavy."
At this point, regardless of Minamikawa Yuu's actual skill level, they had to use him.
Entering the medical department, the sounds of mourning and pain were everywhere.
Wounded soldiers were everywhere, including many with missing limbs, all of whom had been severely injured on the battlefield.
Minamikawa Yuu entered the area with a calm expression and immediately went into work mode.
For Minamikawa Yuu, who had already worked in the Konoha Hospital for some time, this kind of environment was nothing to him; he had long since adapted.
While busy with treatments in the medical department, he also had his own little maneuvers.
"Relax a bit."
A wounded man lay quietly before him, his eyes wide open, appearing to be in intense pain.
Minamikawa Yuu's face was calm. He placed a hand on the wounded man, and with just a light stroke, he easily calmed the man down.
"What did you do?"
Someone nearby asked, very curious about this ability.
"A little trick I developed myself; it helps people fall asleep more easily."
Minamikawa Yuu spoke softly: "In a short time, he can forget the pain and enter a dreamland."
"As long as the movements aren't too violent, he won't wake up."
Hearing Minamikawa Yuu's words, the eyes of those around him lit up.
A Ninjutsu that could easily make people fall asleep had quite a significant use.
Not only could it be used to alleviate the pain of the wounded by putting them into a deep sleep, but it could also solve many problems for the medical staff by making the patients more cooperative.
Taking advantage of a moment when others weren't paying attention, Minamikawa Yuu reached out and pressed a hand against the wounded man's chest.
Along with his movements, the Chakra inside the wounded man's body slowly drained away, absorbed by Minamikawa Yuu and stored within himself.
Chakra Absorption Technique.
Purely in terms of Medical Ninjutsu, the development of the Land of Ancestors might not match later generations, but in other aspects, its development far exceeded them.
Especially in the methods of storing and absorbing Chakra.
To nourish the God Tree and meet various needs, the development of the Land of Ancestors in these two areas was remarkably fast.
As the Emperor of the Land of Ancestors, Minamikawa Yuu naturally had a deep understanding of this.
The Chakra Absorption Technique was a technique he had developed using the entire power of the Land of Ancestors.
Using this technique, one could extract Chakra from others without affecting their health and store it as a Chakra reserve.
This Chakra could be used to release Ninjutsu or fulfill various other needs.
Previously at the Konoha Hospital, because the number of Ninjas was small and most had sparse amounts of Chakra, Minamikawa Yuu hadn't taken much action.
But now, the situation was different.
There were wounded soldiers everywhere, and most were Ninjas.
As long as he used means to put them to sleep, he could openly absorb the Chakra from their bodies without being discovered at all.
For Minamikawa Yuu, this was a perfect environment.
The days repeated like this, one after another.
Until one day, a wounded person was sent from the front lines, shifting Minamikawa Yuu's attention.
That wounded person's name was Kakashi Hatake.
Inside the quiet tent, Kakashi Hatake jolted awake from a dream.
He looked at his hands in horror, as if seeing the bloodstains upon them, his eyes revealing fear and unease.
"You're awake."
A voice sounded from the side.
Kakashi looked up to see a young boy walking in from outside the room, currently looking at him: "I wasn't quite sure when I saw your name earlier, but now it's confirmed."
"We meet again, Senior Kakashi."
"You are..."
Kakashi stared at Minamikawa Yuu in front of him, and only after a good while did he recall the other's identity: "You're the one who had that match with Obito that day..."
He spoke subconsciously, but after thinking of Uchiha Obito, he suddenly fell silent.
The events that had occurred previously echoed in his mind, preventing him from calming down for a long time.
"I've heard about what happened to Senior Obito and Senior Rin."
Minamikawa Yuu sighed: "That's how it is on the battlefield; someone who was alive just a moment ago might become a cold corpse shortly after."
"Perhaps this is the fate of a Ninja."
He spoke softly: "But I think, if Senior Obito and the others were still alive, they probably wouldn't want you to be so grieved over their deaths."
Minamikawa Yuu's voice was very gentle, like a light breeze blowing past, making one feel a hint of warmth.
At the bedside, Kakashi didn't say a word, still sitting there in silence.
In his left eye, a crimson Sharingan was quietly visible, and a special Chakra was currently diffusing from it.
