Jiraiya, new idea!

Boom!

The tree trunk fell, and Shuichi Hoshita took a few deep breaths. He looked at the cut, but it was a trace of carbonization.

"Cutting is indeed easier...with high temperature burning damage."

"The direction is right, but it needs further improvement and refinement."

After eating a Bingliang Pill, Shuichi Hoshita kept summarizing.

He needs more efficient changes in chakra properties, faster chakra operation efficiency, and stronger chakra control.

Physical strength recovered, and continued.

Try again and again, and improve repeatedly.

Such days passed quickly, and the three-day holiday was gone in a blink of an eye, and the mission continued.

However, even during the mission, Shuichi Hoshita did not give up the development of the secrets of swordsmanship.

While taking a break from the northern border patrol mission, looking at Shuichi Hoshita who was concentrating on developing new techniques, Kurama Sanyo scratched the back of his head. He just had the idea of ​​developing illusions, but found that his head was empty.

"I'm not a genius after all!"

Kurama Sanyo sighed dejectedly.

Namikaze Minato smiled and comforted him: "Don't compare with Shuichi. The reason why Shuichi wants to develop his own sword technique is because he has the advantage of fire escape."

"Shanyo, you focus on illusion. The current illusion is enough for you to practice."

Kurama Sanyo was convinced by this sentence, and the feeling of dejection disappeared instantly, and then asked: "Shuichi, if it's fire escape, how to combine it with swordsmanship, or your swordsmanship."

In the tradition of the ninja world, swordsmanship includes the use of swords, and Hoshita Shuichi is used to describing it with swordsmanship.

Hoshita Shuichi raised his eyes and smiled: "The combination of fire escape and swordsmanship is better to say that it is a combination of chakra, ninjutsu and swordsmanship."

"And chakra is used in two directions: property change and form change."

"For example, Minato teacher's Rasengan is a simple use of chakra form change."

"And now I mainly use property change, supplemented by form change. Property change is the change of fire, and the specific manifestation is high temperature."

"Form change involves the operation of chakra, which allows me to better stack fire escape chakra and increase the temperature, so that the knife has stronger cutting power."

Namikaze Minato was very surprised after hearing this: "What a clear development thinking, Shuichi, you have a higher talent in ninjutsu than me. "

Hoshita Shuichi said modestly: "Only on Fire Style."

But Namikaze Minato shook his head slightly: "No, this kind of thinking can be applied to the development of any kind of technique."

At this time, Uchiha Shisui asked: "So, Minato-sensei, your Rasengan can also add property changes and continue to transform into a new technique?"

Namikaze Minato nodded: "Indeed, I have also considered this."

"But there are not many clues yet."

"The change of chakra's nature will make chakra more difficult to control, and the Rasengan technique is already very perfect at present. If the change of chakra's nature is added, it will destroy the original stability."

Speaking of the end, Namikaze Minato couldn't help shaking his head helplessly.

The Rasengan was originally referenced by the Tailed Beast Ball, but now there is no direction for further development.

Hoshita Shuichi certainly knew the Wind Style Rasenshuriken, but he didn't think clearly about the theory, so he couldn't say it.

The timing is wrong!

…

Time passed quickly, and when Shuichi Hoshita finished his border patrol mission and returned to Konoha, it was already October.

On this day, Shuichi Hoshita came out of the Konoha Hospital to find Tsunade at the training ground next to it, but found that there was one more person.

"Jiraiya, he is back... At this time, Nagato and the others are only in their teens?"

Shuichi Hoshita was secretly surprised, and then continued to move forward.

"Tsunade-sama!"

Hideichi Hoshita greeted, then his eyes fell on Jiraiya, and he greeted politely: "Jiraiya-sama, I'm Hideichi Hoshita!"

Jiraiya was talking, turned around and looked down at Hideichi Hoshita: "Eh?"

"Where did you come from, kid?"

"Do you know me?"

"Hahaha, it seems that I haven't been back for a long time, but my name is still very famous!"

Hideichi Hoshita was speechless. This was the first time he returned to Konoha, he did not go to find his disciple Minato, but came to find Tsunade instead.

As expected of a lustful immortal!

And he is also very narcissistic.

Although he was complaining in his heart, Shuichi Hoshita had an innocent smile on his face: "Of course, you are one of the famous Konoha Sannin, an outstanding ninja like Tsunade-sama."

Jiraiya was immediately happy when he heard it, and then posed: "Compared to the title of Konoha Sannin, I prefer you to call me the Toad Spirit Immortal of Myoboku Mountain, commonly known as the Toad Immortal, come and join me!"

Tsunade next to him couldn't help but curl her lips and said: "Idiot!"

Jiraiya's expression froze when he heard it, and he couldn't help but feel discouraged.

Tsunade snorted, "Did you forget to accept a disciple?"

Jiraiya recovered instantly and said with a smile, "Don't worry about Minato. He is a rare genius in ten years and a natural ninja!"

Hoshita Shuichi said at the right time, "Jiraiya-sama, Minato-sensei is my current team leader."

"Team leader?"

Jiraiya smiled and said, "As expected of Minato, he has become a jonin after not seeing him for a few years, and he has begun to support the younger generation!"

But he immediately reacted, "By the way, are you here to learn medical ninjutsu from Tsunade?"

Hoshita Shuichi nodded, and Tsunade waved her hand impatiently, "We are going to start training."

Jiraiya nodded and left in a chic manner, saying, "Let's have a drink together in the evening!"

"Got it!"

Tsunade agreed casually.

Jiraiya left, and Shuichi Hoshita and Tsunade began to practice, but it was not medical ninjutsu, but the Yin seal.

On the other side, Jiraiya walked a distance away and stopped to look back at Tsunade, smiling: "It seems that the situation is not that bad!"

The first thing he did when he came back was to collect folk songs, and then go to see Sarutobi Hiruzen. Only then did he know that Tsunade suffered from hemophobia, so he came to see Tsunade immediately.

Tsunade did seem a little lazy before, but now she seems to be very motivated!

After feeling relieved, Jiraiya turned around to find Minato Namikaze.

…

Because of his high talent, Shuichi Hoshita quickly comprehended the seal.

However, the Yin seal is a very special technique, which is specially used to seal chakra, which also involves the refinement and control of chakra.

Hideichi Hoshita, who practices medical ninjutsu, naturally has a strong ability to control chakra, but there are still details that he needs to ask Tsunade.

Secondly, Hideichi Hoshita's situation is different from Tsunade's.

Tsunade now uses chakra except for sparring with him, and hardly uses it most of the time, so she can store the chakra.

And once the Yin Seal is activated, it must be continued until it is completed, and it must be restarted if it ends halfway.

If the stored chakra is insufficient, it will not be meaningful.

Hideichi Hoshita usually needs too much chakra, training, and missions.

He can't waste three years for the Yin Seal.

Hideichi Hoshita remembers that Haruno Sakura has also encountered this problem, and Haruno Sakura's approach is to open a small pool in the seal to divert the chakra.

The big pool is used for storage, and the small pool is used for daily use.

But Hideichi Hoshita now has other ideas.

"Tsunade-sama, the Yin Seal gathers chakra and stores it on the forehead, but it doesn't necessarily have to be on the forehead, right?"

"The three major meridian circulation systems in the human body, the forehead, the heart, and the belly button, can all reach the whole body."

Hoshita Shuichi asked: "Then, is it feasible to place the Yin Seal on the abdomen?"

Tsunade pondered after hearing this.
