Tsunade was about to leave

Early the next morning, Qingyun practiced his various martial techniques as usual, then took his lunchbox and headed to the Ninja Hospital.

After a full day of treatment yesterday, everyone at the Ninja Hospital knew Qingyun, the youngest medical ninja, and greeted him as he passed.

Qingyun returned each greeting, then made his way to Tsunade's office with practiced ease. Seeing her resting against her desk in exhaustion, he sighed to himself and draped a coat over her.

Then he changed into his work clothes and resumed the treatment work from yesterday.

After yesterday's practice, Qingyun had become much more proficient with the Mystical Palm Technique. His internal force had also grown more refined through repeated depletion and recovery.

Moreover, yesterday's practical experience had shown Qingyun that his internal force was fundamentally different from chakra.

Chakra was energy extracted from the cells within a ninja's body. Once a ninja had exhausted their body's potential, their growth would plateau, and the only way to increase their strength was to work on more powerful ninjutsu.

Internal force was different, especially with the Cultivation Technique modified by the system. The Primordial Chaos Technique could not only absorb natural spiritual energy from the outside world, but also extract energy from his own cells and convert it into internal force.

The Mystical Palm Technique originally used a special energy circulation route to stimulate the cells around an injury with chakra, making them divide rapidly and accelerating the ninja's recovery.

This caused massive cell division within the patient's body, shortening their lifespan.

But when Qingyun used internal force to perform the Mystical Palm Technique, the natural spiritual energy within it repaired the aftereffects of cell division, even though the technique still caused the cells to divide rapidly.

This did not mean Qingyun could heal injuries without any harmful effects, but compared to using chakra to perform the Mystical Palm Technique, the side effects were reduced by more than half.

After discovering this effect of his internal force, Qingyun worked even harder to treat the wounded, because he wanted to see what other hidden effects it might have.

"Qingyun is amazing. He's so young, yet he's already so skilled at Medical Ninjutsu."

"Exactly. Qingyun, why don't you take a break? My injuries aren't that serious right now."

Seeing Qingyun's sweat-covered face, one of the wounded could not help urging him to rest.

Qingyun shook his head. "I'll rest while I recover my chakra after treating you!"

As he spoke, he gathered internal force in his palm and pressed it against the patient's wound. It began healing at a speed visible to the naked eye.

The patient could not help letting out a moan as Qingyun treated him, his expression one of utter comfort.

Before long, Qingyun finished treating him. As the ninja thanked him, Qingyun sat down cross-legged right there to restore his internal force.

What Qingyun did not know was that while he was doing everything he could to save the wounded, Hiruzen Sarutobi, Mitokado Homura, and Utatane Koharu were watching him silently.

"Hiruzen, is this the genius ninja you mentioned?"

Still unaware that Qingyun belonged to the Uchiha Clan, Mitokado Homura looked at Hiruzen Sarutobi curiously as he asked.

Hiruzen Sarutobi watched Qingyun with a complicated look in his eyes and nodded.

At that moment, Hiruzen Sarutobi was deeply conflicted. He did not know whether having Tsunade take Qingyun as her student had been right or wrong.

He had never expected Qingyun to be so talented. At such a young age, the boy not only overwhelmed his peers in combat, but was also so proficient in Medical Ninjutsu that he surpassed even some medical Jonin.

His conversation with Tsunade yesterday had made Hiruzen Sarutobi realize just how much she valued Qingyun. In her heart, Qingyun had already risen to a position second only to Nawaki.

Yet he remembered how Qingyun had handed over his self-created, exclusive Taijutsu to the village for free, without asking for anything in return. And now, he was working tirelessly to treat the wounded without regard for his own exhaustion.

Hiruzen Sarutobi suppressed his conflicted feelings toward Qingyun and even silently reproached himself for being suspicious. Qingyun was wholeheartedly devoted to the village; he should not doubt the boy's loyalty.

Seeing Hiruzen Sarutobi nod, Utatane Koharu looked at Qingyun in a different light and asked curiously, "Judging by his age, he should only be seven, right? Does he really already have strength comparable to a Chunin?"

"At least that much."

The corners of Hiruzen Sarutobi's mouth lifted. He had been the first to discover Qingyun, and now the boy was his student's student. Although Qingyun's background was something of a blemish, he was completely different from the average Uchiha, making Hiruzen unconsciously forget his origins.

"If that's the case, with his strength and proficiency in Medical Ninjutsu, we could certainly have him treat the wounded just behind the front lines!"

Utatane Koharu looked at Hiruzen Sarutobi excitedly.

"There's no need for that yet. His strength is growing rapidly right now. We shouldn't expose this child to the brutality of the battlefield too early. Say no more. I have my own plans for him."

Yesterday's conversation with Tsunade had put Hiruzen Sarutobi on his guard. Qingyun belonged to the Uchiha Clan, whose members were prone to extremes. If Qingyun encountered the battlefield too early and his mindset changed, Konoha might lose a talented ninja. The gains would not be worth the loss.

Moreover, Qingyun was not only proficient in Medical Ninjutsu and far stronger than his peers, but also astonishingly gifted, having already created various Taijutsu techniques at such a young age.

Once Qingyun grew a little older, he might create even more powerful Taijutsu or Ninjutsu comparable to A-Rank techniques, or even higher. If they sent him onto the battlefield and something happened to him, Konoha would suffer an enormous loss.

Hearing this, Mitokado Homura and Utatane Koharu could only nod helplessly. Besides, none of the current battlefronts were particularly troublesome, so it did not really matter whether Qingyun went to the battlefield.

After watching for a while, the three quietly left.

Qingyun had no idea that three members of Konoha's F4 had just been secretly watching him. He had been completely focused on treating the wounded, and so many people around him were looking at him that he had failed to notice the hidden observers as he usually would.

After restoring his Internal Force, Qingyun resumed treating the wounded.

Time passed, and half a month went by. Throughout those two weeks, Qingyun diligently treated the wounded every day. As he became more proficient with the Mystical Palm Technique, the number of patients he treated each day steadily increased, from thirty at the beginning to forty now.

After half a month of treatment, the number of wounded continued to fall. By now, few remained at the Ninja Hospital.

"Qingyun, take a break. I'll take you out for a meal."

Tsunade suddenly came up behind Qingyun and spoke.

Qingyun nodded. "All right, big sis Teacher. Go get changed first. I'll come once I've finished treating this uncle."

Watching Qingyun, Tsunade nodded in satisfaction. His help had made things much easier for her lately, and his Medical Ninjutsu was growing more and more proficient. She was very pleased with this student of hers.

Before long, Qingyun finished treating the patient and left for Tsunade's office. After changing his clothes, he looked at her. "Big sis Teacher, is there something you want to tell me?"

Normally, Tsunade would hardly have the spare time to invite him out for a meal. Her sudden invitation today clearly meant she had something to discuss with him.

"That's right. Tomorrow, I'll be leading these recovered ninja back to the battlefield. Let's have a good meal today."

Tsunade ruffled Qingyun's hair out of habit, then spoke calmly.

Qingyun froze for a moment, then nodded silently. "Then be careful on the battlefield, big sis Teacher. I'll be waiting in Konoha for you to come back."

"Don't worry. Your Teacher is a very powerful ninja. Nothing will happen to me. Come on, I'm taking you out for Yakiniku today."

Seeing the worry on Qingyun's face, Tsunade smiled as she spoke.

Qingyun nodded. Recalling the original story, he remembered that Tsunade had faced little danger apart from her encounter with Hanzō. Reassured, he followed behind her as they walked slowly toward the Barbecue Restaurant.
