Naruto: I, a decent person, have become the mastermind behind all this!

In the bathtub, Shuichi Hoshita closed his eyes and quietly thought about the double agent mission.

As a double agent, the most important thing is to gain the trust of both parties.

Konoha should not be a problem. After all, he will be a Konoha ninja for a long time, and he has his teacher Minato Namikaze as a guarantor. He is also of good family background and has correct ideas.

So how to gain the trust of the daimyo for a long time? Not to mention the mission itself, the daimyo's investment in him is also very important, which can give him another source of income, which he can make as much as possible.

"Introduce some geniuses to the daimyo?"

"For example, Kakashi... It shouldn't be too much to charge 30% to 50% for the introduction fee?"

"But if Sarutobi Asuma is taken away by the daimyo, will he blame me?"

Shuichi Hoshita's thoughts were flying around, and he didn't collect his thoughts until he finished taking a bath.

"My current position is to focus on close combat and then medical ninja."

"Let's not talk about the direction of medical ninja. Close combat will definitely focus on swordsmanship in the future. The Three-Moon Dance is not bad, but it is still a little short of becoming a jonin with this, let alone an elite jonin."

Hiroshita Shuichi thought while putting on his clothes.

Although he is just a genin, he must also think about the future path.

For example, how to go in the swordsmanship route?

"After the Three-Moon Dance, I should first master the changes in the nature of wind escape chakra, and then apply it to swordsmanship, and create my own swordsmanship secrets."

"For the direction of fire escape...it seems that either chakra accumulation or combination of ninjutsu, such as wind escape..."

People's energy and time are limited. If there were no entries, Hoshita Shuichi would definitely stick to the path of wind escape combined with swordsmanship.

After getting dressed, Hoshita Shuichi went out and went straight to Konoha Hospital.

When practicing the art of extracting fine diseases in the daimyo mansion, he accumulated several questions, and he had to find the pharmacist Nono to get the answers.

However, when I arrived at Konoha Hospital, I didn't see the pharmacist Nono, but I ran into Tsunade, whom I hadn't seen for a long time.

"Tsunade-sama!"

Hideichi Hoshita hurriedly greeted him.

"Little boy... are you here to see Nono?"

Tsunade stopped.

Hideichi Hoshita nodded and said, "Yes, I'm here to learn medical ninjutsu."

Tsunade nodded, then walked forward, but stopped after just two steps, turned around and said, "Hey, have you ever thought about further developing your memory palace into a sealing technique?"

Hideichi Hoshita's eyes lit up when he heard it, and he turned around and asked, "Does Tsunade-sama have this idea too?"

"I have tried it before, and I want to fix the memory palace in my mind with a curse seal, so I developed a technique, and then asked Minato teacher, and got further improvements."

Tsunade frowned slightly when she heard it: "That guy Minato... his sealing technique is not bad."

She knew Namikaze Minato, of course, he was Jiraiya's disciple and Uzumaki Kushina's lover, and he also learned the sealing technique from Uzumaki Kushina.

"If that's the case, then it's fine."

Tsunade waved her hand and turned to leave.

Hoshita Shuichi hurriedly stepped forward to stop her: "Tsunade-sama, although we have the same idea, we may not take the same path. It is very necessary to exchange ideas with each other. Maybe we can gain more."

Tsunade hesitated for a moment, then nodded: "Then let's go to my office!"

...

In the office, under Tsunade's gaze, Hoshita Shuichi copied the sealing technique that was perfected by Minato Namikaze.

Tsunade folded her arms and watched, and when Shuichi Hoshita finished, she nodded and said, "This technique is already very complete."

"Make the memory palace illusion spatial, shape and reinforce it with sealing techniques, and freely control the input and output of memory."

"So this sealing technique is specially prepared for certain memories?"

Shuichi Hoshita gave a thumbs up: "As expected of Tsunade-sama."

"The original idea was to prevent the impact of memory on the brain after the shadow clone was released."

Tsunade listened thoughtfully: "Shadow clone? You want to practice with the shadow clone?"

"Then be careful, in addition to memory, there is also fatigue, and you will tire yourself to death if you are not careful."

"But Minato That guy should have warned you, right? "

Hiroshita Hideichi nodded, and then asked: "Tsunade-sama, do you have any ideas?"

Tsunade did not answer, but asked: "What do you think is ninjutsu?"

"This..."

Hiroshita Hideichi frowned, thought for a while and said: "Use chakra, this energy, to release it in different forms."

"For example, wind, fire, lightning, or illusions, etc."

Tsunade nodded: "Very good description."

"There are many techniques, including but not limited to curse seals and sealing techniques, which can be set on the body in advance and then used at any time."

Hiroshita Hideichi immediately thought of the Hyuga clan's caged bird sealing technique.

This sealing technique includes two modes: active and passive triggering.

Active, that is, the main family can control the caged bird at any time to damage the brain of the branch family and make the Byakugan blind.

Passive triggering means that once the branch family members die on the battlefield, or are captured, and the enemy digs out their eyes, the sealing technique will be triggered to damage the Byakugan.

In addition, what impressed Shuichi Hoshita was the [Inner Four Symbols Seal] of the old man Danzo.

The binding seal that fixed Uchiha Sasuke's body during the battle should have been prepared in advance and could be activated in an instant.

However, such sealing techniques and seals would not be simple, otherwise they would have been everywhere.

Hoshita Shuichi thought: "Tsunade-sama wants to use it to seal medical ninjutsu?"

Tsunade nodded: "The original memory palace is just a method of memory. Most people should be able to learn it."

"After being transformed into a seal, the illusion of the memory palace is spatialized, and the seal is spatialized to create an existence like a library. The memory is turned into a book or even a person."

"Then the medical ninjutsu can be stored in the same way and can be called at any time when needed. There is no need to seal it."

Hoshixia Shuichi was secretly shocked when he heard this.

Is this an idea that indigenous people should have?

But if you think about it carefully, it is not uncommon in the ninja world to set up the curse seal in advance and then use it instantly.

There are even Ninjutsu scrolls that contain Ninjutsu, which Shikamaru Nara used when he fought against Kakuzu.

But it's obvious that Tsunade's idea is systematic and large-scale.

And it has to be done in the human brain.

After thinking for a moment, Hoshixia said: "Tsunade-sama, there is a huge difference between simple memory and spells, seals, and ninjutsu."

The original Memory Palace was a systematic, associative memory trick.

To put it simply, it is to achieve the effect of quick memory, long-term memory, and even permanent memory by associating the items to be remembered with well-known places.

Hoshita Shuichi is now using the familiar Konoha, and it is precisely because of this that he had the idea of ​​turning this memory trick into a sealing technique.

And did it.

But ninjutsu and memory are different.

Memory is just human thinking, and ninjutsu also requires chakra energy.

As Shuichi Hoshita previously answered Tsunade, the process of performing ninjutsu, if you do not consider the seals, can be simply described as controlling the energy of chakra to be released in different ways and properties.

"Of course I know that."

Since Tsunade came up with the idea, she naturally thought about it.

Hoshixia Xiuyi smiled and said: "This is indeed a very amazing idea."

"This is equivalent to solidifying a certain medical ninjutsu in the brain. Not to mention the difficulty of solidifying medical ninjutsu, once there is a problem with the seal, even if the medical ninjutsu breaks out, the consequences will be very serious."

Tsunade said nonchalantly: "What kind of ninjutsu is not dangerous?"

"The memory palace can store memories in a systematic way. If it can also store medical ninjutsu in a systematic way."

"For example, with the technique of Yin Healing and Injury Destruction, there is no need to predict the enemy's attack."

"The transmission of thinking consciousness and nerve signals is faster than any movement. Ninjutsu can be launched the moment before the enemy hits."
