Yin Healing Wound Bullet

Uchiha Ling felt no guilt whatsoever; after all, in his view, it had truly been an accident, and he had committed no untoward acts.

On the contrary, he was quite curious to see how Tsunade would handle this situation.

"Watch closely!" Tsunade seemed intent on breaking the suffocatingly awkward atmosphere by diving straight into the lesson.

She raised her right hand, and chakra rapidly condensed in her palm. However, it did not form the usual green glow of healing; instead, it emitted an obscure, destructive fluctuation.

"This technique is called Yin Healing Wound Destruction." Tsunade spoke faster than usual, as if reciting from a textbook. "Its principle is not traditional healing, but rather the pre-accumulation of a massive amount of chakra within the body.

The moment you are attacked by an enemy, you guide this chakra precisely to the injured area—not to repair it, but to drastically accelerate cell division and regeneration.

Before the damage is fully realized, you forcibly 'cancel' or 'reverse' it. From the outside, it looks as if you were never injured at all."

She explained the principle concisely, doing her best to avoid unnecessary chatter or eye contact.

Then, she walked over to a sturdy wooden post, clenched her left fist, and struck the sharp edge of the post with a violent blow.

With a crack, the skin on the back of her hand was instantly sliced open, and blood began to seep out.

But almost at the same time the wound appeared, a dense radiance of chakra covered the injury.

As the light faded, the wound on the back of her hand had vanished without a trace, leaving not even a scar, as if the attack had been nothing more than an illusion.

"That is how it's done." Tsunade shook her hand, her tone flat, attempting to describe this miraculous technique as something as simple as eating or drinking.

"The key lies in the ultimate control of chakra, as well as precise anticipation and reaction at the exact moment of injury. It requires an intimate understanding and mastery of one's own body."

The demonstration finished, she looked at Uchiha Ling, her gaze still somewhat shifty. "You... you should try to understand the principle first. Accumulate the chakra, simulate the guidance at the moment of injury..."

She gave a very vague instruction, a far cry from her usual meticulous, hands-on teaching style.

Tsunade just wanted to minimize close contact and verbal communication with Uchiha Ling as much as possible right now.

Uchiha Ling was far too clever; he understood Tsunade's state immediately.

He chuckled inwardly, though on the surface, he maintained an appearance of earnest diligence.

"Yes, Teacher. I will give it a try."

Uchiha Ling closed his eyes and began to mobilize the chakra within his body according to the principles Tsunade had described.

A different kind of silence fell over the training ground.

It was no longer the tranquility of focused cultivation, but rather an invisible, awkward tension that permeated the air.

Tsunade stood where she was, feeling every second drag on interminably.

She could feel Uchiha Ling's chakra flowing steadily, which indicated he was indeed practicing seriously, but this did not help her relax.

The boy's very presence was like a silent reminder, constantly poking at her sensitive nerves.

She couldn't help but glance at Uchiha Ling from the corner of her eye. His focused profile was sharp, his nose bridge high, and his black, messy hair hung over his forehead, giving him a composure that transcended his age.

Suddenly, a thought uncontrollably intruded into her mind: last night, it was with these eyes, which now looked so calm and unruffled, that he saw...

Stop! Tsunade abruptly cut off her own train of thought, her cheeks flushing hot once again.

She forced herself to shift her attention to the distant forest, but her mind could not truly find peace.

Although Uchiha Ling had his eyes closed, his perception was exceptionally keen.

He could "hear" Tsunade's slightly hurried breathing and "feel" her restless gaze, which occasionally swept over him before quickly darting away.

Uchiha Ling knew that his teacher's heart was far from as calm as she appeared on the surface.

The feeling of having the subtle emotions of such a powerful woman under his perception gave him a strange sense of satisfaction.

Therefore, Uchiha Ling was in no rush to break this state; instead, he was happy to play along, maintaining this master-disciple interaction that was calm on the surface but surging with undercurrents beneath.

After a long while, Uchiha Ling slowly opened his eyes and spoke: "Teacher, I have some questions regarding the density and stability of the chakra accumulated at specific points in the body..."

Uchiha Ling posed a technical question, his tone sincere, as if he had truly encountered a difficult hurdle.

Tsunade's body stiffened slightly.

What was meant to come would come; close-quarters guidance was unavoidable. She took a deep breath, trying to make her voice sound normal. "Where?" She stepped closer, but still maintained a greater distance than usual.

Uchiha Ling extended a finger, pointing vaguely at several acupoints on his arm. "Is it here, and here? I feel that when the chakra gathers here, the flow doesn't seem smooth enough..."

Tsunade was forced to focus her gaze on the spots Uchiha Ling indicated.

Once she was close, the faint scent of the boy, a mixture of sweat and sunshine, wafted over, causing her heart rate, which had only just begun to settle, to spiral out of control again.

She reached out her index finger, wanting to point it out to guide him as she had before, but her fingertip stopped a few centimeters away from the skin of Uchiha Ling's arm, as if there were an invisible barrier.

"Hmm... those are roughly the right positions."

Tsunade's fingertip trembled slightly, but in the end, she did not make contact, merely gesturing through the air.

"The flow of chakra needs to be gentler; it cannot be too forceful, or you will damage your meridians... You should try to feel it for yourself."

She finished speaking rapidly, then retreated two steps like a startled rabbit, putting distance between them.

This obvious avoidance and stiffness were enough to make even Uchiha Ling find it somewhat amusing.

Uchiha Ling nodded, not pressing further, but instead continuing to practice "earnestly," while in reality, he was savoring the rare sight of Tsunade's embarrassment with great interest.

The rest of the time was spent in this bizarre atmosphere.

Tsunade did her best to provide guidance with the briefest of words, avoiding any unnecessary contact or eye contact.

Uchiha Ling, for his part, cooperatively played the role of a diligent and eager student, occasionally posing questions that maintained this delicate balance just right, all while watching Tsunade struggle within the whirlpool of awkwardness he had created.

By the time the training neared its end, Tsunade felt almost completely drained.

This kind of mental tension was far more exhausting than a full-blown, heart-pounding battle.

"Let's... call it a day here."

Tsunade announced the end of the session as if she couldn't wait a second longer.

"You already understand the principles of Yin Healing Wound Destruction; the rest is just a matter of grinding out the practice. Consolidate what you've learned on your own."

Having said that, she didn't even dare to linger, turning and walking briskly away from the training ground; her retreating figure carried a hint of someone fleeing in a panic.

Watching Tsunade's rapidly disappearing back, Uchiha Ling finally allowed an undisguised, playful smile to curl the corners of his lips.

Uchiha Ling stretched his wrists slightly, looking at the system energy in his panel that had surged after absorbing a large amount of "awkwardness" and "annoyance."
