Uchiha Yoichi directed a lightning bolt at the wall, directly charring the Wood Release wall.
After experimenting for a while, he undid the Spirit Transformation Jutsu and returned to his body.
When his soul returned to his body, Uchiha Yoichi felt a heaviness; compared to his soul form, his body's speed was much slower.
"It's not very difficult, but the limitations when using it are too great... It's similar to the Sharingan, but far inferior."
Both the Spirit Transformation Jutsu and the Sharingan offer great benefits for one-on-one encounters, but the Spirit Transformation Jutsu is very limited; it's best used for surprise attacks, but if the enemy is prepared and dodges the first round of attacks, the user of the Spirit Transformation Jutsu is in trouble.
And in the Ninja World, there are plenty of escape Jutsus; simply mastering the Substitution Jutsu allows you to dodge twenty meters away in one second.
"Let's see how long it will take to develop the Spiritual Clone Jutsu. Would it be faster if I synchronized the research with the Research Assistant...?"
Uchiha Yoichi thought to himself, then opened the Superpower Roulette.
[Research Assistant] can conduct three researches simultaneously, and because there's only a month, Uchiha Yoichi chose two projects that were relatively easy to improve for the first two.
Doubling the speed of the Lightning Release Chakra Mode requires twenty-one days.
Optimizing the Navy Rokushiki requires nine days.
The third research project is the combination of the Spirit Transformation Jutsu and Clone Jutsu, for which Uchiha Yoichi provided the requirements to the [Research Assistant] to see the needed research time.
"Forty-three days? Exceeding by thirteen days... Oh well, I'll just use the three lottery chances."
After a brief consideration, Uchiha Yoichi decided, as the Spiritual Clone is pivotal to controlling the physical clone in the future. If he ever obtains Dual Kamui Sharingan, he plans to transplant them to the physical clone.
In this way, he would possess an entire Divine Power Space.
After assigning the research tasks to the ability, Uchiha Yoichi walked out of the room, where Nohara Rin was waiting. She noticed him coming and walked over gently, asking in a soft voice: "Teacher Yoichi, have you finished your training?"
"Mm, sorry Rin, I haven't been able to spend much time with you lately, lots of things in the village..."
Nohara Rin immediately shook her head upon hearing this and smiled sweetly: "It's alright, Teacher Yoichi is an important person in the village. Occasionally teaching me Ninjutsu is already very generous."
"Rin, you're so well-behaved..."
Uchiha Yoichi said with a smile, then reached out and touched Nohara Rin's short auburn hair.
Nohara Rin closed her eyes and slightly moved her head as if enjoying the gesture.
"Rin, recently during a mission in the village, many ninjas were killed or injured. During this mission, they seem to have discovered the mastermind who put the Tailed Beast in your body back then..."
Uchiha Yoichi thought for a moment and decided to tell Nohara Rin about it, only altering the fact that he already knew about Uchiha Obito, telling her he had just discovered the intelligence.
Black Zetsu is the mastermind, and last time when Jiraiya went on a mission, Black Zetsu was surely watching, so saying this isn't wrong.
"Just wait a little while longer, when the village fully investigates them, then you can come out."
Nohara Rin's face flashed with joy upon hearing this, and she nodded like a little bird: "Mm, I trust Teacher Yoichi."
If she can go out, she surely wouldn't want to stay here, although Nohara Rin feels that it's already quite good now, with Teacher Yoichi guiding her training and accompanying her in Alchemy...
"Thank you, Teacher Yoichi."
"No big deal, no need to thank me."
Uchiha Yoichi waved his hand, thinking that if Obito knew Nohara Rin wasn't dead, he might rush back to apologize; at that time, Uchiha Yoichi would find it a bit tricky to deal with Obito for the sake of his pride.
But he still wanted Kamui, so asking Obito to die was the only option.
When he commits a more serious crime, even if Obito finds out Nohara Rin is alive, he won't be able to return to Konoha, and even if he makes up his mind, he will meet his end upon returning.
Uchiha Yoichi is no holy saint, he doesn't have the heart to forgive so easily.
"Teacher Yoichi..."
Nohara Rin saw Uchiha Yoichi heading towards the Alchemy Room and, driven by joy and impulse, grabbed his sleeve and asked with a slightly flushed face,
"You've been busy all morning, should, should I give you a massage? The last time you mentioned it, we still haven't..."
After hearing Nohara Rin's words, Uchiha Yoichi remembered what he had said before, though he had to return due to village matters.
"Then I'll trouble you, Rin."
"It's no trouble, I've learned a lot from books recently..."
Nohara Rin blushed slightly, then took Uchiha Yoichi to the resting area and patted the bed, slightly lowering her head: "Teacher Yoichi, please lie down on the bed."
Among the books she'd recently read, some mentioned that sitting on a man's back during a massage could bring pleasure and enhance its effectiveness.
There were also illustrations, and when Nohara Rin read them alone at night, her face was deeply flushed; she initially wanted to close them and switch to another book, but not wanting to give up halfway, she covered her eyes and peeked through her fingers to finish reading them.
After finishing, she felt embarrassed and curled up in her blankets, staying awake almost the entire night, her mind running wild; some of these books were brought by Teacher Yoichi, was it a hint?
Then Nohara Rin thought about how she was resurrected by Teacher Yoichi, who took good care of her, gently teaching her powerful Ninjutsu and rare Alchemy Skills...
Having spent months in the underground Alchemy Room, Nohara Rin only ever talked to Uchiha Yoichi, her previous memories sealing away bit by bit, replaced by memories of her time with him.
And those memories were so beautiful, they brought a youthful smile to her face as she thought about them.
"Do I need to lie down?"
Uchiha Yoichi felt that since this was Nohara Rin's bed, it wasn't appropriate for him to lie on it. He could use Wood Release to create a new one; but Nohara Rin softly replied "Mm," and patted the bed again, so Uchiha Yoichi had no choice but to lie down.
"Teacher Yoichi, I'll start the massage now..."
Nohara Rin's cheeks flushed, she then made up her mind and directly sat on Uchiha Yoichi's back, her soft teenage hips felt as if they were sitting on steel.
This sensation made her blush even more, but Nohara Rin suppressed her emotions, gathered Medical Ninjutsu in her hands, and pressed them on his back.
It was a genuine massage, using Medical Ninjutsu to soothe muscles and meridians, providing a unique comfort to Uchiha Yoichi.
However, this also consumed a lot of Chakra, after all, the Mystical Palm Jutsu is A-Class Medical Ninjutsu, meant for emergency treatment, and is seldomly used for massages.
During the massage, Nohara Rin kept adjusting her sitting position, and these subtle movements were quickly noticed by Uchiha Yoichi, but he was still immersed in the comforting massage of Medical Ninjutsu.
Usually practicing with the Lightning Release Chakra Mode made him accustomed to pain, and suddenly having such an experience felt extraordinarily good.
After a while, Nohara Rin's face was covered in fine perspiration, and she slowly came to a stop.
After the massage, Uchiha Yoichi sat up and gave her a thumbs up: "Rin, that felt wonderful, thank you."
"You're welcome, if Teacher Yoichi likes it, I can, I can continue doing this for you in the future..."
Even though Nohara Rin was tired, seeing the smile on Uchiha Yoichi's face filled her with immense satisfaction.
And Teacher Yoichi's body is so strong, just remembering the firm muscles she touched earlier makes her heart race.
