Naruto: The God of Bloodlines

Thus, Yasu understood that even if Obito didn't learn to use the **Mystical Palm Technique**, Rin would still spend more time with him, focusing on teaching him. In that way, Yasu would have fulfilled his promise to Obito.

"Alright, I've shown you how to use the jutsu and even demonstrated what you need to do during training. Now it's your turn. Come to the stones, use the technique on the fish, and try to revive them," Rin said with a laugh.

Rin was excited to be teaching Yasu and Obito. While she felt happy and energized seeing her friends grow stronger, it was hard for her to deny feeling a twinge of envy toward their talent.

Kakashi was already far ahead of them and could soon become a jonin. Obito, who was much stronger than her, would almost be on Kakashi's level once he awakened the Sharingan.

Even Yasu, who had been under their protection and had not yet become a shinobi, had grown stronger than Obito through sheer effort. He had the potential to become as strong as Kakashi in the future once he could learn the village's jutsus.

At least in medical ninjutsu, Rin was considered a genius student. It took her only a few months from learning the Mystical Palm Technique to being able to use it on other shinobi and even perform surgeries.

Many at the Konoha hospital said that if Tsunade hadn't left the village, she would undoubtedly have chosen Rin as her student and successor. Rin was also regarded as a strong shinobi, even without considering her prowess as a medical ninja.

One of her motivations for teaching Obito and Yasu was to see them struggle with learning medical ninjutsu and perhaps even temporarily give up. At the very least, she expected it would take them over a year to heal anyone effectively.

As Rin reflected on this, Yasu and Obito stepped forward to the large stones and eyed the fish lying on the scrolls. Obito focused first on how to release a fixed amount of chakra from his hands before beginning to heal the fish.

But Yasu didn't need to worry about that. He had already trained his chakra control extensively to be able to achieve this, and even if he hadn't, he still possessed the basic knowledge to at least start using the **Mystical Palm Technique** thanks to the system.

Yasu knew he had little time to learn from Rin, and he didn't want to waste it pretending he didn't know how to use the technique from the start. He couldn't afford to fake a slow learning process.

As soon as Yasu used the Mystical Palm on the fish, a green chakra flowed from his hands toward the fish. Rin, who had been momentarily distracted, was quickly shocked to see that Yasu had perfectly activated the technique on his first attempt, with flawless chakra output.

With her experience, Rin realized that Yasu was already capable of reviving the fish and could bypass several of the initial stages of medical ninjutsu training she had prepared. She even thought that Yasu might already be able to attempt healing someone in an emergency, if necessary.

As expected, while Obito was still training to adjust his chakra output, the fish in front of Yasu came back to life and began jumping around after being healed by Yasu's Mystical Palm.

Obito, who hadn't even started the practical training yet, was stunned to see that Yasu had already completed the task. He also noticed that Yasu had taken only slightly more time than Rin herself had needed to revive the fish.

"Well done, Yasu! I'm really impressed. You must be a medical ninjutsu genius. I've never seen anyone learn the Mystical Palm Technique so quickly. If I didn't know about your situation, I'd think you had already learned this technique before," Rin said.

"With your current skill, it might still be risky to move on to the next stages, such as healing injured animals, since any mistake could kill them. But you can move on to even more advanced stages and train on healing larger fish," Rin added.

Rin's initial plan didn't work with Yasu, but she was happy to see that her friend was a **medical ninjutsu genius.** Rin felt glad to be able to say that, for a time, she had taught a genius how to use medical ninjutsu.

Soon, Rin retrieved a very large fish from a sealing scroll. It was one of the fish she had prepared for the final stage of Yasu and Obito's training. She had thought it would take at least a year before she would use one of these fish.

"Yasu, to revive this fish, you'll need to maintain constant chakra control for a long period of time. If you don't have a lot of chakra, use only a small amount. Genin can use this technique, but the less chakra you use, the longer it will take to revive the fish," Rin explained.

Rin had started using large fish only during the final stages of her own training in the **Mystical Palm Technique.** After she succeeded in healing animals, she was able to begin healing other shinobi and gradually gained experience.

The purpose of this training was to prepare medical ninja for long surgeries. During a lengthy surgery, the medical ninja must maintain focus the entire time and constantly release the same amount of chakra for hours to use the Mystical Palm Technique and heal the patient.

Rin had struggled greatly with this technique and took months to successfully revive large fish consecutively. However, she thought Yasu would have less difficulty with this training since he was a genius.

The reason Rin didn't have Yasu work on healing injured animals was that he had only used the technique once. If he miscalculated the amount of chakra needed to revive a fish, the fish would get cooked. However, if he made a mistake while healing a small animal, the animal would die.

Rin expected that Yasu would still make many mistakes since he had only just learned the Mystical Palm Technique. She felt sorry at the thought of animals dying because of his errors. Therefore, it was better for Yasu to train with a large fish. Once he completed this training, he would be ready to heal animals and even other shinobi.
