Starting with Wood Release, he survives in Konoha Hospital and becomes a big shot.

"This is called a chakra scalpel. It can directly attack the meridians inside the body. I just severed the meridians in my left hand. Try using your eye technique to heal me," Tsunade said directly.

The best way to understand Yao Xingji's pupil technique is to experience it for yourself.

Tsunade was aware of her hemophobia, so she skipped external treatment and chose to use the chakra scalpel to attack her own body to see how effective the Eye of Salvation's healing would be.

“Yes, Tsunade-sensei,” Yao Xingji said earnestly.

To help herself understand the details and effects of her eye techniques, Tsunade didn't hesitate to experiment on her own body; it would be a lie to say she wasn't moved.

"The Eye of Salvation!"

Chakra surged into Yao Xingji's eyes, and a faint red ripple spread from them. At the same time, Yao Xingji clearly saw the broken meridians on Tsunade's arm and immediately activated the healing effect of the Eye of Salvation.

Buzz! Yao Xingji's eyes grew brighter and brighter, while Tsunade felt a warm, tingling sensation in her arm. Soon, the broken meridians were reconnected.

Gang moved his arm and could hardly feel that he had just been injured; the treatment was very effective.

On the other side, Yao Xingji also smiled.

Tsunade herself came to him for treatment.

Chapter 80 Chakra Properties

[Healing ninja complete, increased own chakra by 30%!]

[Acquired the ninjutsu - Chakra Scalpel!]

[Gain the power to create the Azure!]

The prompt from the Heart of the Universe in his mind made Yao Xing extremely happy; he had once again gotten Tsunade for free.

Although the chakra gained from healing was less than that from the first treatment, the rewards for healing a Sannin-level ninja were still very generous.

Chakra Scalpel is also a good ninjutsu. It can enhance Yakusei's combat power and also greatly help him when treating other ninjas.

"The treatment is more effective than the Palm Healing Technique, takes less time, and provides almost a complete recovery without leaving any aftereffects or affecting the upcoming battles," Tsunade said, clenching her left hand to assess the extent of her meridian recovery.

"How much chakra did you use?" Tsunade asked immediately, remembering Shizune saying that this eye technique consumed a lot of chakra.

"There's probably about half left," Yao Xingji said in a very low voice.

This eye technique consumes a lot of chakra, but that's for a three-year-old child. In reality, Yakusei's chakra is already close to five katakana, which is much more than the chakra in the body of an average Jonin. Although it can't compare to Tsunade's level, it's not far off.

Don't be fooled by the fact that each treatment increases chakra significantly; that's all based on the increase in Yakusei's own chakra reserves. Given his current limited chakra, the increase isn't actually that dramatic.

"Well, actually, for your body, this amount of chakra is already quite astonishing," Tsunade commented.

“Chakra is an energy extracted from human cells and fused with spiritual energy. Therefore, the amount of chakra is closely related to the body. Except for some special constitutions, most people have very little chakra when they are young. As the body grows, the amount of chakra can gradually increase. The fact that you were able to refine this amount of chakra at such a young age, coupled with your training in the Palm Healing Technique, shows that your talent is something I have never seen before,” Tsunade said earnestly.

Previously, when she was in the hospital, Tsunade had examined Yao Xingji's body and found no problems. In fact, during some of the examinations, she discovered that Yao Xingji's physique was even better than that of ordinary ninjas, which she found quite amazing.

If this child had been handed over to her for upbringing earlier, his achievements would probably be even greater now.

Yao Xingji listened to Tsunade's words while also pondering.

He had always been curious as to why the original owner of this body was able to learn the Healing Palm Technique, a medical ninjutsu, at such a young age, which was indeed somewhat contrary to the common sense of the ninja world.

However, when he looked through the original owner's memories, he did not find the answer he was looking for.

It seems that learning the Palm Healing Technique was not a challenging thing for the original owner. What made Yao Xingji even stranger was that he could not find any memory of Yao Shi Nono teaching him the Palm Healing Technique. He still did not know where this ninjutsu came from.

He always felt that this original body seemed to be hiding some unspeakable secret.

“Alright, you’ll be taught about chakra when you go to the Ninja Academy. Our current focus is mainly on medical ninjutsu, but I’d like to confirm your chakra attribute first.” Tsunade said, taking out a chakra attribute test strip.

“When you infuse chakra into the paper, it will undergo different changes. For example, if your chakra attribute is wind, the paper will split in the middle; if it is fire, the paper will burn. And so on, each attribute will produce different changes,” Tsunade explained.

“Okay.” Yao Xingji took the chakra test strip; he also wanted to know what the attribute of his chakra was.

Because of the existence of the Heart of the Universe, Yao Xingji can actually obtain and use any ninjutsu, but this use is not the ninjutsu used by Yao Xingji himself, but is used with the help of the Heart of the Universe.

"If I can use medical ninjutsu, then my chakra nature must include Yang, but I don't know about the others..."

While Yao Xingji was secretly grumbling to himself, he extracted chakra and slowly injected it into the chakra test paper.

Time passed, one second, two seconds, ten seconds... the chakra test strip showed no reaction!

Huh? What's going on?

Yao Xingji was somewhat bewildered.

Tsunade frowned as well. She could feel that Yakusei's chakra had entered the chakra test strip, but why was the test strip not reacting? What was going on?

"Teacher, there seems to be no response." Yao Xingji looked up at Tsunade, asking for an explanation.

Has anyone in Naruto ever experienced a similar situation? Yao Xingji thought for a moment, and it seemed that never had.

"Could it be a problem with the test strip?" Tsunade said uncertainly, taking the chakra test strip from Yakusei's hand and injecting her own chakra into it.

The next moment, part of the chakra test paper got wet, part burned, and part wrinkled and shattered, indicating that Tsunade's chakra possessed four attributes: water, fire, lightning, and earth.

“The chakra test strips are fine.” Tsunade frowned even more, her gaze towards Yakusei filled with doubt.

Where exactly did Yakushi Nonou find this child?

"Try again!" Tsunade said, handing over another chakra test strip.

Yao Xingji took the test strip and injected chakra into it.

Just like before, there was no response.

"This shouldn't be happening! How could this be?" Tsunade muttered to herself.

This was the first time she had encountered such a situation; the chakra test strips couldn't detect the properties of the medicine star.

Does this mean that Yao Xingji's chakra is only of the Yang attribute?

Yao Xingji frowned. Since the chakra test strip didn't react, did that mean his chakra didn't have these attributes?

However, there are two explanations for this situation. One is that Yao Xingji's chakra does not possess the five attributes of wind, water, lightning, earth, and fire. The other explanation is that Yao Xingji's chakra has no attribute.

Without any attribute, the chakra test strip will naturally not react, but the absence of attribute also means that Yakusei's chakra can be of any attribute.

That's quite amazing.

"Tsunade-sensei, could my chakra be attribute-less?" Yao Xingji voiced his guess.

"No attribute?" Tsunade was taken aback, then fell into deep thought.

This situation was indeed unexpected for Tsunade, and she was also unsure whether chakra attributes had such a special characteristic as being without attributes.

Tsunade gave Yakushi Hoshiki a deep look. This kid's background seemed to be somewhat complicated. Perhaps only Yakushi Nonou knew the specifics of his situation.

However, in order to figure out the matter of chakra, Tsunade thought of two people who might know: Orochimaru, who studies the ninja's body, and Sakumo Hatake, who is knowledgeable and experienced.

------------

Chapter 81 Ninjutsu Talent

Of course, Tsunade's teacher, the Third Hokage Hiruzen Sarutobi, who was known as the professor of ninjutsu, might also have known about this situation.

However, Tsunade harbored resentment towards Hiruzen Sarutobi for using Yakushiki as bait. In addition, her teacher's attitude towards Yakushiki was not good, and he never regarded Yakushiki as a member of Konoha. This made Tsunade unwilling to go to him because of Yakushiki.

The remaining two are Orochimaru and Sakumo Hatake.

"Let's put aside the chakra nature issue for now. I'll ask around and see if anyone knows anything about it. Let's learn basic medical ninjutsu first," Tsunade said.

Putting aside the matter of chakra attributes for the time being, Tsunade began to teach Yakusei some basic medical ninjutsu, as well as the techniques for using ninjutsu.

Yao Xing nodded obediently.

An afternoon passed quickly, and Tsunade's gaze towards Yakusei changed from calm to shock.

Yao Xingji's talent in medical ninjutsu can no longer be described as merely good; it has reached a level that even Tsunade would marvel at.

Tsunade only needs to teach him once, and Yao Xingji can basically master many medical knowledge and treatment techniques. With a little practice, he can become proficient. This kind of talent is simply a gift from God.

"No wonder, no wonder he could learn the Palm Healing Technique at such a young age. With such talent, nothing is impossible..." Tsunade looked at Yakusei, who was working hard to heal a carp not far away, and the amazement in her eyes was beyond words.

"Success!"

With a startled cry from Yao Xingji, the carp that had been lying dead immediately sprang to life, as if it had just been pulled from the water.

"good."

Tsunade nodded and said calmly.

Heaven knows how speechless Tsunade was at that moment. When she was the same age as Yakushiki, she was still playing gambling games with her grandfather. She had no idea what medical ninjutsu was. But now Yakushiki could use medical ninjutsu to perform treatments on her own.

At that moment, Tsunade felt as if she had been hit by tons of damage.

"Teacher, have I met your requirements?" Yao Xingji walked over carrying the carp and asked happily.

"I guess I could manage it. When I was your age, I did much better than you," Tsunade said nonchalantly.

Yao Xingji pursed his lips, clearly seeing the envy and jealousy in Tsunade's eyes.

In fact, Tsunade didn't teach him much. Yao Xingji was also seriously learning about the application of medical ninjutsu. The main reason why he was able to master these things so quickly was because he was a top student who graduated from medical school in his previous life. His research and mastery of medicine were superior to Tsunade's. Based on this, it was very simple for Yao Xingji to learn how to use medical ninjutsu to save people.

It's like playing a game. In your past life, you were a top-tier player in the Chinese server. Now, after being reborn, you're given a new account to start over. You not only have the memories of being a top player in your past life, but you're also given cheat codes. How could you possibly not play well?

"Alright, that's enough for today, you..." Tsunade was about to end today's lesson when a thought suddenly struck her.

Since Yao Xingji has already refined chakra and has such a talent for medical ninjutsu, what about in other aspects?

Tsunade then realized that she seemed to have entered a blind spot in her thinking.

She always attributed Yao Xingji's talent to medical ninjutsu, but in reality, Yao Xingji, who could refine chakra and perform palm techniques at the age of three, should also have a strong talent in other ninjutsu.

Thinking of this, Tsunade picked up the medicine star without saying a word and ran towards the hospital exit.

"So soft, but it's a little... hard to breathe..." Yao Xingji thought to himself.

Tsunade was still analyzing Yao Xingji's condition along the way and didn't pay much attention to the person in her chest.

"Tsunade-sensei... I'm about to suffocate." Yao Xingji's weak voice came through, and Tsunade then noticed that Yao Xingji's face was flushed and he was barely breathing.

"Ah... I'm sorry." Tsunade quickly relaxed her arm.

However, she didn't put Yao Xingji down. She still held him in her arms and rushed outside quickly. After all, a three-year-old child wouldn't understand anything.

Soon, Tsunade brought Yao Xingji to a grove of trees outside the hospital.

After putting down the medicine star, Tsunade said, "Your talent in medical ninjutsu is beyond doubt, but I'm curious whether you also have such talent in other ninjutsu besides medical ninjutsu."

Yao Xingji was still not fully recovered from the face wash she had just used, and was stunned by Tsunade's words.
