The essence of Yin Healing Wound Destruction is based on having mastered the Mystical Palm Technique, by predicting the location of an enemy's attack and using Chakra in advance to stimulate cells to self-heal prematurely, thereby offsetting the damage.
As for Healing Active Regeneration, it integrates other Medical Ninjutsu on top of Yin Healing Wound Destruction, possessing an extremely powerful healing effect, but the burden is immense; in the original work, it required Shizune to lead multiple high-level medical teams working in tandem to perform it.
If performed by a single person, it becomes Tsunade's Creation Rebirth, which requires releasing the massive amount of Chakra stored in the Yin Seal to activate the Strength of a Hundred Seal mode, granting an incredibly powerful, near-immortal body for a short period.
Before her Chakra is exhausted, as long as she is not killed instantly, Tsunade in the Strength of a Hundred state can keep fighting in her complete, peak condition.
Now that his own Yang Release is so potent and his Chakra levels have reached the scale of a Tailed Beast, what would the effect of using Yin Healing Wound Destruction be? And could he, before the Creation Rebirth technique is even created, manage to achieve that kind of effect all by himself?
"Karin's innate talent in the field of Medical Ninjutsu is absolutely one in ten thousand. If it can be developed, it is definitely something worth looking forward to."
With this thought in mind, Uchiha Gen immediately dried his body, reached out, and condensed a thin blade of Wind Release to cut his palm.
A shallow wound appeared, and he then placed his hand over it to perform the Mystical Palm Technique.
This time, in just over ten seconds, his palm returned to normal, nearly twice as fast as before.
"The healing speed is several times faster than before, which is indeed a very good result. However, if the wound were deeper, it would be impossible to achieve that instant self-healing effect; the healing output of the Mystical Palm Technique still has an upper limit."
Uchiha Gen extended his palm once again.
This time, after brewing for a few seconds, he used Wind Release to cut it again.
White mist steamed, and almost the moment Uchiha Gen moved the rotating Wind Release blade away, the wound on his palm turned from red to white, recovering in the blink of an eye.
"The healing effect of Yin Healing Wound Destruction is indeed very strong, but the Chakra consumption is significant. Moreover, if the prediction is off, it's just a waste of Chakra. It's no wonder that in the original work, after Yakushi Kabuto used it once, this technique never appeared again."
Looking at the slight bloodstain on his palm, Uchiha Gen's eyes were thoughtful.
The effect of Yin Healing Wound Destruction is indeed powerful; the first Rasengan Naruto ever created in his life was blocked by Yakushi Kabuto without injury using this technique.
Looking through the original Naruto series, although both Obito and Orochimaru seem to have taken a Rasengan head-on with their physical bodies more than once, regular Ninja would basically lose their lives after taking one hit, which shows just how powerful its healing effect is.
However, after blocking Naruto's unexpected Rasengan, Yakushi Kabuto didn't have much Chakra left, which shows just how massive its consumption is.
For the vast majority of Ninja, the significance of this technique in actual combat is not high, and its cost-effectiveness is extremely low.
Although it can save one's life at a critical moment, the extremely high learning difficulty and the huge Chakra consumption are enough to shut out the vast majority of Ninja.
Then what about himself?
"Let's go out and give it a try."
Thinking of this, Uchiha Gen immediately put on his clothes and released his sensing ability.
He wanted to test his current sensing effect and find a suitable place nearby.
But in an instant, Uchiha Gen slightly furrowed his brows, taking a few seconds to adjust.
His current sensing range was ridiculously large.
Under the effect of Kagura Shingan, his sensing range expanded by a full thousand times!
The sensing range that was originally only a few dozen meters suddenly became dozens of kilometers.
This is the most powerful Sensing Ninjutsu in the Ninja World in terms of range and precision.
The mountains, landscapes, living creatures, and all activities within a radius of several dozen kilometers poured into his mind along with his perception.
Enduring such an excessive amount of information in an instant, even with Uchiha Gen's mental strength, it took him a full few seconds to adapt.
"It shouldn't be used like this; otherwise, even if one were proficient in this technique and could adapt quickly when opening Kagura Shingan, the brain would not be able to quickly retrieve so much information in a short time.
The reception of information should be able to be prioritized."
With a slight movement of his eyes, Uchiha Gen simply sat cross-legged and began to explore it directly.
A few minutes later, he had grasped some tricks.
In the original timeline, Karin likely focused directly on filtering Chakra signatures, directly filtering out other information.
"I can do this kind of thing too."
Uchiha Gen calmed his mind, cast aside distracting thoughts, and began to cast out the unnecessary information he was receiving, leaving only two most important indicators.
Terrain and the fluctuations of Chakra signatures.
The more than two thousand Ninja remaining in the entire Konoha main camp, as well as the various strongholds and patrol teams distributed within several dozen kilometers, were all reflected in his mind, and in addition to that, there were many other Chakra sources elsewhere.
"Using this technique to scout enemy situations and command the battlefield is quite good. By cross-referencing it with the issued missions, one can judge which Chakra sources are in suspicious locations and immediately dispatch Ninja to search those positions.
On the battlefield, one can also grasp the dynamics of both sides' teams in real-time, making more accurate judgments and commands.
As for now, let's attend to the main business first."
A few minutes later.
By the river outside the Konoha camp.
This was near the place where he last met Danzo.
I have to say, although this old guy is bad, he certainly has ability.
After Uchiha Gen searched with his sensing ability, he concluded that this was also the place near the camp least likely to attract attention.
A Shadow Clone split off and nodded slightly at the original body.
"Original, I'm coming."
A bright blue Rasengan appeared in the Shadow Clone's palm.
"Come on."
Uchiha Gen gathered his Chakra and nodded at the Shadow Clone.
The next instant, the Rasengan pressed against his body, knocking the former flying and blasting him into the forest behind.
A few seconds later, Uchiha Gen pushed aside the tree that had been knocked over and was pressing on him, slowly stood up, and looked at his chest.
A large hole was torn in his clothes, revealing red skin underneath, which was making a hissing sound, steaming with white smoke, and rapidly recovering from the injury, soon returning to normal.
"I can withstand the damage of the Rasengan, but I cannot prevent the impact caused by the attack; this point needs attention. Moreover, it requires advance preparation through prediction. I have the Three-Tomoe Sharingan, so prediction is not a problem, and the Chakra consumption is still within the acceptable range. With my current Chakra level and recovery speed, I can indeed normalize the use of this move in battle, just needing to be careful not to overdo it and ensure the attacks I take do not exceed the healing range of Yin Healing Wound Destruction."
Looking at his chest, which had returned to its original state, Uchiha Gen summarized this in his heart.
