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

After the Big Eater temporarily ranked first, Hoshita Shuichi focused most of his energy on developing new techniques with Tsunade.

It would be best if it could be developed this year without having to have a 'flash of inspiration', so Shuichi Hoshita can use the once-a-year 'flash of inspiration' elsewhere.

For example, comprehend the spells given by the half entry tree on Tiancong Dao.

Or it can be used to study four-tailed melting, or even eight-tailed tail clones and substitutes.

There are too many places that are needed, but they only come once a year, so save when you can.

Sometimes time is very valuable, but sometimes it is not.

Of course, although Tsunade is busy, there are shadow clones responsible for the training of many ninjutsu.

Time just flashed to December of the 42nd year of Konoha.

Hoshita Shuichi's vacation is over.

On this day, he returned to ANBU. After entering the locker room and waiting for a while, he only saw Sarutobi Shinnosuke and Chihiro. He suddenly had a premonition in his heart.

Sure enough, the next moment Sarutobi Shinnosuke said: "Shika and Kokoro have exited the ANBU system."

Xingxia Xiu nodded, and then asked: "Will there be new people coming in next?"

Sarutobi Shinnosuke shook his head: "Not yet. Next, we will form a team of three to carry out the mission."

But then he smiled again: "There should be no particularly important missions this year, so for the time being, I will serve as the bodyguard of the Third Hokage!"

Qianxun also smiled and said: "I heard that you have been busy experimenting and developing new techniques recently. You should use shadow clones when the time comes."

"The Third Hokage will basically not leave the village at the moment."

Xingxia Xiu nodded: "Understood, then we will have to trouble the captain and Sister Xun next!"

This was indeed good news for him.

At present, Tsunade's development of new techniques has reached a critical moment. Participating in the development of this technique is not only helping Tsunade, but also a process of exploring his own talents and enriching his experience.

So a new mission began, and the three came to the Hokage Building to garrison.

When Sarutobi Hiruzen wasn't going out, Hoshita Shuichi and the others were at the Hokage Building. What they usually had to do was run errands for Sarutobi Hiruzen and call people.

When Sarutobi Hiruzen went out for a stroll, they followed him relatively secretly.

Quite laid back!

So Hoshita Shuichi was ordered to be lazy and leave a shadow clone behind, while the real body came to the Senju ancestral home.

Shizune was in Konoha Hospital, so Tsunade was the only one at home.

But Hoshita Shuichi discovered that she... fell asleep!

At this moment, Tsunade was lying on the table, not knowing what sweet dream she was having, but her mouth was drooling.

Oh~~

Hoshita Shuichi sat across from her, then looked at it, and suddenly thought: Should I poke her face with my hand?

Evil thoughts popped up in his heart, but Hoshita Shuichi suppressed them immediately.

With Tsunade's temper, she would probably hunt him down for a hundred streets.

Shaking his head, Hoshita Shuichi did not wake up Tsunade, but packed up the scroll next to him and looked through the records.

Basically, they are all incomplete techniques, some are purely Tsunade's handiwork, and some are in which he has participated.

Hoshita Shuichi reorganized and sorted out his thoughts, then took out a new scroll and began to write spells and revise them.

Two hours passed in the blink of an eye. Tsunade woke up and was startled when she saw Hoshita Shuichi: "Hey, aren't you going to perform a mission?"

"Because it's an easy task, I can be lazy."

Hoshita Shuichi raised his head as he spoke, and then couldn't help laughing.

Because Tsunade, who still had a lazy air, had writing on her cheeks.

It's so cute...

"Tsunade-sama, here..."

Hoshixia Shuichi pointed to his face.

Tsunade wiped it and blushed a little, but then said nonchalantly: "I stayed up too late last night."

After saying that, he got up and went to wash up.

When she came back, Tsunade had regained her energy and asked, "Any ideas?"

Hoshita Shuichi was speechless: "Tsunade-sama, I am a genius, but not a god."

"First sort out all the previous results and then talk about it."

Tsunade nodded helplessly, and then began to collect the scrolls scattered everywhere.

In a blink of an eye, it was noon. Hoshita Shuichi started cooking by himself. Tsunade leaned against the door with an apple and looked at it: "It looks pretty good!"

Xingxia Xiuyi smiled and said: "That's natural, I've been practicing it since I was young."

Tsunade pouted: "You are still just a brat now."

"But I will grow up sooner or later, Tsunade-sama."

"But in front of me, he is still a brat."

There was so much noise and lunch was finished before I knew it.

After cleaning up, the two continued to work.

I spent the next two days sorting out the previous results and then continued to advance step by step.

Suddenly 10 days passed.

On this day, the technique was initially formed, and Tsunade started to try it directly.

She formed a seal with her hands. When the seal was completed, with the Yin seal on her forehead as the core, the curse seal immediately began to spread and intersect throughout her body.

Immediately afterwards, the Yin seal was released!

The next moment, Hoshita Shuichi felt a huge surge of chakra.

In his induction, Tsunade had become a huge collection of chakra.

But Tsunade herself frowned slightly: "The circulation of chakra is not stable enough, and the control is not precise enough."

After hearing this, Shuichi Hoshita smiled and said: "Then continue to revise. At this point, it has actually been successful, isn't it?"

"All right!"

Tsunade nodded slightly dissatisfied, and then the traces of the curse seal on her body disappeared, and the chakra poured back into the Yin Seal and sealed it again.

The next step is a long period of improvement, trial, and improvement.

The technique is adjusted little by little, and it keeps moving towards the expectations of Shuichi Hoshita and Tsunade.

December 24, 42nd year of Konoha.

In the Senju ancestral home, next to the stove, Shuichi Hoshita wrote the last stroke, and completely completed this complex technique.

Shuichi Hoshita looked up at Tsunade across from him: "Tsunade-sama, name this technique!"

Yes, before the New Year comes, the new technique is finally completely finalized.

Tsunade looked at the technique on the scroll, nodded and said: "Let's call it the Hundred Healings Technique!"

Shuichi Hoshita wrote the name of the technique immediately.

Then, he took out another blank scroll and continued to write.

Tsunade looked at him with some doubts, and raised her eyebrows after a moment: "You want to use three Hundred Healing Techniques?"

"Even if you set a Yin seal on the forehead, heart, and abdomen respectively, there is no need to use three Hundred Healing Techniques, right?"

"Even if the curse seal technique is set in advance, it still requires energy to maintain, which will increase your mental pressure."

Hoshita Shuichi continued to write, and smiled: "But we must also consider the situation if the curse seal technique is destroyed."

Tsunade hummed: "The core of the Hundred Healing Technique is in the forehead. If it is destroyed, the person is dead..."

The voice suddenly paused, and Tsunade frowned and thought: "You want to be hit in the head, or the brain, and the consciousness coma technique can also work to treat the fatal injury of the brain."

Tsunade said with some surprise: "Did you consider this when you considered adding the Eight Diagrams Seal?"

You know, when a person dies or loses consciousness, the technique will disappear, such as the shadow clone.

But before developing the Hundred Healings Technique, Shuichi Hoshita suggested that the heart and abdomen be used as the other two layered and graded control cores to create two shadow clone-like chakra control cores to share the control pressure and reduce the control difficulty.

But if a person loses consciousness due to a severe head injury, these two control cores will also lose their function, just as the shadow clone will disappear.

But adding the Eight Diagrams Seal is different. It will play a protective role. This part of the control core still has a separate thinking consciousness.

This is the magic of the sealing technique!

It is also the magic of chakra!

Chakra can carry people's thinking consciousness and even soul.

The clones of the clone technique have separate thinking consciousness, which is also the reason.

In the original work, Minato Namikaze sealed the remaining chakra of himself and Kushina Uzumaki in the Eight Diagrams Seal. When Naruto was affected by the Nine-Tails and wanted to remove the Nine-Tails seal, he revived and appeared, interrupting it.

And when Naruto was practicing the Nine-Tails Chakra mode, Kushina Uzumaki also appeared to help.

Sealing technique, omnipotent!

…

Seeing that Tsunade understood, Shuichi Hoshita smiled and said, "Although we don't know what kind of healing ninjutsu we can develop now, at least it can be a seal-free healing and regeneration."

"If the brain is severely damaged and loses consciousness, as long as the brain cells are healed before a large area of ​​rapid death, it can still be revived."

"The three cores need to be destroyed before we lose the healing ability."

"Although not completely, it can also be said that the two rapidly fatal vulnerable parts of the head and heart are no longer weaknesses to a certain extent, and are not so fatal."

Tsunade nodded solemnly, and felt the pressure in her heart: "It seems that we must devote all our energy to developing this medical secret technique, otherwise we will be looked down upon by this kid."

Next, she needs to develop a medical secret technique with a fast enough healing speed to match Shuichi Hoshita's idea.

Otherwise, the three treatment cores are just decorations, and are simply chakra storage places.

When this thought came to her mind, Tsunade thought of her grandfather, the first Hokage, Hashirama Senju.

"My grandfather's sealless healing, even if I can't reach that level, I can't be too far behind!"

...

Looking at Tsunade's solemn expression, Hoshita Shuichi smiled and said, "Tsunade-sama, don't be so stressed. We still have plenty of time."

Tsunade's Hundred Healings Technique is used to assist in medical treatment, to maintain her appearance, and to prolong her life.

But his Hundred Healings Technique can be used to assist in combat.

The Fire Release Chakra Mode can finally be activated!

...

After the new technique was written, Hoshita Shuichi spread the scroll on the floor, then took off the forehead protector, took off his shirt, and revealed his strong upper body.

Then he sat cross-legged on the scroll, and then clasped his hands together under Tsunade's gaze.

The next moment, the technique on the scroll came alive, and the tadpole-like talismans quickly climbed onto Hoshita Shuichi's body, gathering on his forehead, heart, and abdomen under the navel, and combined with the Yin Seal and Bagua Seal that had been arranged long ago.

When the ritual was completed, Shuichi Hoshita said softly: "Open!"

The next moment, under Tsunade's gaze, Shuichi Hoshita's originally smooth forehead burst into blue light.

It was a round shape different from the diamond shape of the Yin seal on her forehead, like a round light spot.

Obviously, this has a lot to do with the Bagua seal.

However, what surprised Tsunade was that she clearly sensed Shuichi Hoshita releasing the Hundred Healings Technique, but no curse seal appeared.

But Shuichi Hoshita's chakra had quickly filled the entire head and appeared on the surface of the body, rendering the entire head with a layer of blue chakra.

"Is this the benefit of using the Bagua seal? Chakra control can be brought to the maximum level."

"wrong!"

Tsunade's eyes narrowed: "This is... fire escape chakra!"

At this time, the chakra on Hoshixia Shuichi's head quickly converged and returned to his forehead, and then the blue light spot on his forehead also disappeared.

But then, Tsunade saw a blue light spot also light up in the heart of Shuichi Hoshita, and then blue chakra quickly covered the surrounding area.

Go up to your neck, then your entire chest, and your arms.

Tsunade looked at it and couldn't help but thought to herself: "The three cores can be opened separately, just like Yin Healing and Injury Destruction. This can indeed save chakra and avoid over-healing."

At this time, Shuichi Hoshita had completed his attempt at the art of hundreds of heroes on the heart.

Next is the abdomen. The scope of this operation is the abdomen and the lower part of the abdomen, including the legs and feet.

In other words, he divided his body into three areas.

The trouble is a little troublesome, but it also has many other benefits.

Moreover, for spells that have been arranged in advance, they can be activated with just one thought or seal, and there is no waste of time.

Of course, the three cores can cover the whole body, not just a part.

Everything was perfect, Hoshixia Xiuyi immediately stood up and put on his shirt.

As for the ninja forehead protector, he thought about it and tied it around his neck instead of his forehead.

Tsunade asked at this time: "Hey, is there another use for the Hundred Heroes' Technique?"
