Aoba's Chakura no Mesu(Chakra Scalpel) directly cut open Danzo's skin and muscles from the back.

The other two shadow clones immediately used both hands to heal the part of Danzo's body that was cut open, preventing the blood from flowing out.

In addition, a shadow clone used Saikan Chushutsu no Jutsu(Delicate Illness Extraction Technique) to extract all the bacteria on the wound, preventing Danzo's body from being infected because of the cut.

Puchi!

Thick yellow water began to flow out from the swollen bump on Danzo's back. This yellow water was all extracted by Aoba's chakra.

After dealing with the bump. Aoba's gaze fell on Danzo's spine.

At this time, he could clearly see it. Danzo's spine had been dislocated to a certain extent. This dislocation caused the surrounding nerves to be damaged, causing the body to become crippled.

"Let's go together!"

Aoba said to the remaining four idle shadow clones.

What he needed to do now was to adjust Danzo's spine and reconnect the damaged nerves around it. Then, through Shosen Jutsu(Mystical Palm Technique) and the special ointment, he would restore the damaged part to normal.

In the following time, Aoba's main body and the four shadow clones began to reconnect these nerves.

This was a cell-level operation. It could be said to be very difficult. It required an extremely meticulous operation.

Aoba had already involuntarily concentrated his chakra on his eyes in order to see the scene in front of him more clearly.

Aoba then sighed with emotion in his heart.

Whether it was Kumogakure's style of rampaging through training's body techniques or the delicate operation of medical ninjutsu, if he could get Byakugan, it would be a qualitative improvement.

In the future, it was possible to organize the Hyuga clan to transform in the direction of medical ninjas.

Those acupuncture points could have high attainments in massage.

Such a plan appeared in Aoba's mind, but this matter only passed in the blink of an eye. He paid more attention to Danzo's treatment.

Unconsciously.

Time passed by.

Half an hour.

One hour.

Two hours.

...

Aoba had operated for five hours. Even with his physical fitness, he felt that his eyes were a little blurry. However, he had no intention of stopping. This level of surgery can not press any pause button from the middle. It must be one step at a time.

If it didn't succeed, then it was a failure.

Next time, if he wanted to do it again, it could be said that it was extremely difficult. There was no such good condition as now.

Aoba controlled the state of his body and tried his best not to shed a single drop of sweat. Including the four shadow clones, there were five people with ten hands. The tips of each hand surged with chakra, and the nerves on Danzo's spine were reconstructed bit by bit.

Another half an hour passed.

The operation had arrived at the most critical moment.

The sky outside had already darkened. Koharu next to him turned on the light and was afraid that it would suddenly pierce Aoba's eyes, but if she did not turn on the light, she was worried that Aoba could not see clearly.

She wanted to ask. But she didn't know if she should open her mouth. Would she disturb Aoba?

Of course, Aoba did not care about this. He quickly used both of his hands to stir up the last nerve. All the damaged nerves would be completely repaired if this nerve were repaired.

The next moment, the four shadow clones next to Aoba immediately took out the ointment at the same time. They applied it to Danzo's newly built spine and nerves. After they finished applying it. They start to gather the surrounding muscles little by little.

Combined with Shosen Jutsu(Mystical Palm Technique). Gradually, the damaged parts of Danzo's body began to heal.

This process looked fast but actually slow. It needed to repair every part of the cut blood vessels and tissues.

After Aoba finished all of this. He slowly let out a sigh of relief.

He personally completed this kind of delicate operation, and it still took some effort. Before he did this operation, he thought of what Tsunade looked like when she performed the operation for Rock Lee at that time.

'It is just as Tsunade said.'

'Either succeed.'

'Or die.'

After all, Tsunade did not have a sealing technique like Soul Imprisonment Seal to lock the soul inside.

Although Aoba did not have any use for it, the existence of such a thing could indeed reduce a lot of pressure, allowing him to be more focused.

Aoba then turned Danzo back from [B] to [A] and wrapped the bandage on the latter's body again. The wound covered by the bandage on Danzo's body was a burn. His skin had already changed.

The right eye that was not opened was a Sharingan. However, he did not expose this matter.

Now that Danzo had been implanted with Kinkoju no Fuda(Forbidden Individual Curse Tag, it could be said that it still had some effect on him. For the time being, Danzo would not reveal his secret.

Aoba quickly put on Danzo's long robe again in his body, and then together with a few shadow clones, they carried Danzo back to the bed.

"It's done."

Aoba turned around and looked at Koharu. As he spoke, there was a burst of air around him, and all the shadow clones had disappeared.

"Thank you for your hard work."

Koharu nodded at Aoba. She got up and walked in Aoba's direction. Her pace was not fast, but it gave people a feeling that she was closing in step by step.

As Koharu walked in the direction of Danzo's bed. She seemed to be walking toward Danzo, but in fact, she was compressing Aoba's space step by step.

"This list is for you."

Aoba took a piece of paper from his ninja pouch, which listed all kinds of herbs. He held the list in his hand and handed it to Koharu, who came over.

A trace of doubt flashed in Koharu's eyes. She took the list and looked at it, finding it full of herb's names.

The most important thing was… This was not a simple herb. It was all kinds of poisonous herbs. Each type of poisonous herb had a dosage marked on the back.

The front also had a number.

Starting from No. 1 to No. 17, each number was a kind of poisonous herb, but behind No. 18, there was nothing written.

"What is this?"

Koharu looked at the words on the list, and small question marks appeared in her head. It did not look like a medicine used to treat Danzo's injuries. It was more like poisoning or detoxification.

After all, Koharu was also a medical ninja. She still had the least knowledge of these herbs. As long as she saw the name, she would have a corresponding description in her mind.

"This is for Danzo-sama to take. According to the dosage on the list, it should be taken twice a day for a total of three days. This way, Danzo-sama can gradually recover." Aoba said slowly.

"The herbs on the list should all be poisonous herbs, right?" Koharu narrowed her eyes and asked. She could no longer see what Aoba was up to.

"That's right, they are all poisonous herbs, but when they are put together, they are antidotes." Aoba nodded and said.

"You mean..." Koharu was confused. She stared at Aoba and asked in confusion, "Danzo was poisoned?"

"That's right!" Aoba nodded again.

"When did this happen? Why didn't I find it? Could it be that Third Raikage's attack was poisoned? This is too sinister!" Koharu immediately felt a wave of lingering fear in her heart. She felt that it was fortunate that this mysterious person had discovered the matter of Danzo being poisoned. She could not help but become even more curious about this mysterious person's identity.

"As you can see, when I was repairing Danzo-sama's sternum and ribs, I applied a special healing ointment. I mixed the ointment with poison. It was not Third Raikage who poisoned him, but me." Aoba said seriously. From his calm tone, it seemed he did not know how shocking his words were.

"What?!"

When Koharu heard Aoba's words, she was stunned for a moment. She was completely dumbfounded. She never thought that this mysterious man would say such words. It could be said that he did not hide it at all!

"What do you mean by this?"

Koharu frowned and stared at Aoba with a cold and threatening look in her eyes. She seemed to be very angry.

In her opinion, the mysterious man in front of her was using this method to threaten them. If they don't help him. Then Danzo would be poisoned to death.

It looked like he was treating Danzo, but in reality, he had other plans to use this despicable method to seek benefits.

"Koharu-sama should be very clear about why I did this, right?" Aoba said meaningfully.

"What do you want?" Koharu asked coldly. She already had the intention of turning hostile.

"I don't want anything."

Aoba shook his head. His pair of pitch-black eyes focused on Koharu's face through the hole in the mask, making him look so calm and composed.

"I want to leave quietly after treating Danzo-sama. I don't want to cooperate with your investigation." Aoba said indifferently.

"You are thinking too much." Koharu shook her head. She needed to stabilize the mysterious man in front of her. After all, the other party had the antidote to detoxify Danzo.

Although the list was in Koharu's hands.

However, she knew that there were only 17 types of poisonous herbs in her hands, but No. 18 was missing. This meant that the person in front of her had hidden it.

"Am I thinking too much?"

As Aoba said this, he kept shaking his head and said in a mocking tone, "Does Koharu-sama take me as a fool, or do you think I am a fool? After I treat Danzo-sama, you have blocked all my paths. If I didn't give you this list, you would probably take off my mask now!"

"This is just your guess." Koharu was noncommittal, but her body did not move forward or retreat. She did not block Aoba again, but she also did not give way.

"Koharu-sama, since it is my guess, please don't block my way out and let me leave here. I will tell Brother Eaton the No. 18 herb. At that time, you will naturally get the antidote to the poison in Danzo-sama's body," Aoba said indifferently. It was not that he did not dare to fight here, but once the fight broke out, then the Third Hokage in the other room would come. If he wanted to leave, he could only use Hiraishin no Jutsu(Flying Thunder God Technique). Otherwise, his identity would be exposed. After all, Eaton knew who he was.

However, if he used Hiraishin no Jutsu(Flying Thunder God Technique) to immediately left here. Then, the matter of him using Hiraishin no Jutsu(Flying Thunder God Technique) would also be known by Eaton.

In the end, if Eaton were unable to withstand Hiruzen's interrogation, he would still reveal his matter.

Therefore, just to be cautious. Aoba made such a plan.

"If I let you go now, but you didn't give us the antidote and threatened us with such a thing, then we would be in trouble!" Koharu said without giving in at all.

"If I want to attack Danzo-sama, then I don't have to spend so much effort to save him!"

Aoba said lightly, directly giving a reason that Koharu could not refute.

"Koharu-sama."

"You are also a medical ninja."

"I'm sure you know very well what kind of situation Danzo-sama is in."

"If I don't come to save him, he will spend the rest of his time in bed."

"Do you think it is necessary for me to harm such a person?"

Aoba's eyes flashed with a faint light. It could be said that he didn't care about this matter at all.

Now he had saved Danzo. Then he was Konohagakure's hero. But this hero's name had no meaning to him at all. It might even be a burden.

"If I let you go, you will definitely tell Eaton the No. 18 poisonous herb?" Koharu asked in a low voice. She had already been convinced by Aoba's words, but she did not want to give in so easily. After all, she was now representing Konohagakure's higher-ups.

"Of course."

Aoba nodded and did not say anything else. He just quietly looked at Koharu. From the exposed eyes, the face behind the mask seemed to be smiling.

"I understand."

Koharu nodded helplessly. Just as Aoba had said, she had wanted to take off Aoba's mask to see who Aoba was.

However...

She had never expected things would escalate to this point!

Looking at it now. The other party completely led her by the nose.

The mysterious man, who was wrapped up so tightly that no one could tell his identity, and only revealed a little bit of information: he was young.

At such a young age. He planned such a detailed plan.

Koharu could not help but become more curious about the identity of this mysterious man.
