"Oh, it's actually spiritual transformation technique and Akita's double transformation technique?" Sarutobi Hinata said in surprise.

The major families of Konoha will also record some basic secret techniques into the Book of Seal to indicate that the ninja village and the family are one. However, firstly, these secret techniques are all basics, and secondly, although the secret techniques have not formed a blood-stained boundary, they also have a certain blood inheritance. Except for the original race, it is difficult for outsiders to learn their secret techniques.

Therefore, even if the Seal Book contains secret techniques from various races, no one is willing to learn them, especially the secret technique of Akita, which requires fat, is only the degree to which Konoha is rejected by the insect-raising technique of the Oil Girl family.

However, not many people have learned, but many people have learned from it. Since Shusarutoki wants to develop medical ninjutsu, it is normal to learn from the secret technique of Yang Dun of Akita's Yang Dun.

However, the spiritual transformation technique is an advanced ninjutsu of Yin Dun. It has amazing effect and great defects. When used, the body cannot move, and it can't fight against the enemy in a way that the soul leaves the body, which has little to do with medical ninjutsu.

Although he was puzzled by Sarutobi Cho's choice of spiritual transformation, Sarutobi Hiruzen did not ask the details. After these few times, he still had confidence in his nephew and believed that he had his own ideas.

Sarutobi Tsuki recorded the ninjutsu and was secretly happy. With the technique of spiritual transformation, he could also try to study the Taoist scriptures of Yangshen.

The Taoist Sutra of Yangshen is the closest item to immortality in the reincarnation warehouse. Although there are many problems, the upper limit is only at the ghost immortals, and there is no such thing as thunder tribulation in the ninja world. However, you have to walk step by step and eat the rice bite at a time. It is always wrong to study it first.

However, there are many dangers in the Taoist scriptures, so he dare not cover his head and practice. First, take a look at the ninja version of "soul out of body" and then compare it, and you can... leave it to Orochimaru for practice.

Well, anyway, the tool man will not practice until he has achieved results.

As for the flying thunder god he was thinking about, the reincarnation of the filthy land, it was not only found in the seal book, but also in the Thousand Hand House!

With my relationship with Tsunade, how difficult is it to borrow some? Why waste it on the Book of Seal? Although Naruto is his uncle, he cannot open too big back doors for him.

After choosing ninjutsu, Sarutobi Toru left Naruto's office and returned to his own laboratory to prepare for the production of potions.

The office door was pushed open again, and Danzo walked in with a cold expression.

"Do you still want him to join my squad? This is no joke."

"Didn't you always think that ninjas have to go through battles? Why have you changed your mind now?" Sarutobi Hiruzen said with a smile.

"He is so important, for his safety..."

"For his safety, we must let him go out for experience! Archer already has the power to be close to a special Ninja! If he doesn't go out for missions like this, when will he go out for missions? Will he go again during the war?"

"But if other countries know..."

"The news didn't spread so quickly! It would take at least several years for them to know! This period is the best time for Archer to grow. If Archer doesn't try to train and lacks strength, it will be even more dangerous in the future!"

Danzo was silent for a while, "Okay, I understand!"

Sarutobi Hiruzen also breathed a sigh of relief: "Danzo, please give me."

In the sunset, in the training ground.

Forgotten Jiraiya: "Is there anyone? Come and save me!"

A week later, the laboratory.

"Well, Orochimaru grew by 83%, Haki Sakumo grew by 82%, Danzo teacher grew by 37%, and Uncle Hi-shou grew by 42%. Is this the chakra growth rate for everyone?" Sarutobi Toru pondered to himself.

"Why am I at the end?" Next to him, Tsunade, who looked unhappy, sat on the chair and complained in a low voice.

Sarutobi couldn't help laughing and comforted: "Because Tsunade, you are different!"

Tsunade turned red slightly, and she turned her head and said, "What are you saying, are you lying to me again."

Sarutobi picked up Tsunade's inspection information and thought to himself: "I didn't lie to you. As a Thousand Hand Clan, your potential is far superior to that of others!"

For Tsunade, who valued the most and also had the greatest potential, Sarutobi Toru had to design the most perfect solution to strengthen her.

A few hours later.

"Everyone else uses oral administration, right? Why do I need to use injections?" Tsunade asked cowardly, looking at the needle tube.

"I said that Tsunade, you are different from others. Your potential is far beyond others. Naturally, you need to use a more advanced formula!" Sarutobi Tsuna looked at Tsunade's expression and almost laughed. Unexpectedly, Tsunade, as a ninja, was afraid of getting an injection?

Tsunade gritted her teeth and said, "Come on!" and then stretched out her arm.

Sarutobi reached out and grabbed Tsunade's arm, pushed the potion into the blood vessels, and took advantage of Tsunade's nervousness and his nails pierced into the skin of her arm.

In an instant, Sarutobi Toru, who activated his fruit ability, felt all the hormones in Tsunade's body and had the ability to manipulate these hormones at will, and this manipulation was a permanent change.

In the past, Sarutobi Tsuki did not use the ability to manipulate hormones directly, but instead added medicines to prevent problems from being seen. After all, the effect brought by his own abilities has exceeded the limit of the efficacy.

But Tsunade is different. As the descendant of the Thousand Hand Clan, no matter how effective the potion is, it can be pushed to the physical condition. Anyway, people in this world are the most greedy.

After a while, Tsunade fell asleep deeply, and Sarutobi took her to the sofa in the laboratory and covered her with a blanket.

Tsunade felt that she had a good dream, and she was warm all over. She slowly opened her eyes and saw Jiraiya's idiot face.

Boom! Jiraiya screamed, was knocked away for a long time, and hit the door.

At this time, Tsunade discovered that the room was full of people, Sarutobi Toru, Orochimaru, Hiruhu, Naruto, Sarutobi Hinako, and an old woman with red hair, who was her grandmother Uzumaki (Senye) Mito. She was accompanied by some electrodes, detectors and other things on her body.

"Are you awake?"

"Okay, I've said it all, this is a normal situation, don't worry! I'm a special potion for Tsunade, how could something go wrong!"

Sarutobi Tsubaki talked to Uzumaki Mito and Sarutobi Hinako while helping Tsunade take down the detector.

"What's wrong?" Tsunade asked confusedly.

"You have been sleeping for two days!" Uzumaki Mito glared at Sarutobi and said to Tsunade.

Sarutobi Tsubaki had to smile bitterly. Tsunade, who possesses the genetic genes of the immortal body, had extremely huge potential in his body. After the endocrine system was reorganized, the time for self-adjustment exceeded his imagination.

However, this also proves that the benefits Tsunade got this time are probably extremely amazing.

"Tsunade, how do you feel now?" After being glared at Uzumaki Mito, Sarutobi Tsuki quickly found a way to change the topic.

"I feel... I've never been so good!" The chakra in my body surged, almost ten times as much as before I fell asleep. My body was full of strength, and the world seemed to have become clearer.
