After being slightly stunned, the pharmacist replied with a smile "yes".

This is not the first time that the two sides have fused physically. When the first generation of cell transplants was performed before, in order to transport the immortal chakra, the bodies of the two briefly blended together, and now they can be called familiar.

And as Yakushidou entered the immortal mode, the two breaths gradually became indistinguishable from each other, and from an outsider's point of view, even a ninja who was good at perception would never be able to detect the second will from it.

"Well done."

Orochimaru bowed slightly, and said with his thoughts, "It doesn't matter if the rest is done, when you perform the operation, leave the control of your body to me for the time being."

"I see."

Yakushidou nodded, and after making sure that all the preparations were correct, he pushed open the door and walked out slowly, heading straight for Nagato's secluded residence.

After making up his mind to let him have surgery, Nagato also gave him permission to come and go freely, so get ready to come and look for him directly.

Of course, there are limits to this free entry and exit.

Almost as Medicine Master reached the door of the black spire, a ghostly figure floated out of the shadows.

Xiao Nan stared coldly at Yakushidou, as if she wanted to see through it all, but no matter how she looked at it, she could only see a mask with a smirk, just like the expressionless cold face on her face.

"Do you mean you're ready to come here?" Xiao Nan asked coldly.

The medicine man pushed his glasses upwards and said with a smile, "Of course, after all, it is to operate on the man behind the 'god', how dare you be careless."

"You'd better not make any small moves."

Xiao Nan stared at the pharmacist's pocket, and suddenly his arm broke inch by inch, turning into a piece of white paper and floating into the air.

A little fire flashed, and the white paper was ignited in the rain and exploded.

The air wave pushed the water mist, and a puff of smoke and dust shook in front of the medicine man, and a solemn warning suddenly sounded in his ears,

"This tower, these buildings, are all made by me with detonation charms, if you dare to do anything, just wait for him to be buried."

The medicine man looked around, and the sense of disobedience in his mind became clear, and the corners of his mouth outlined a disdainful smile, "Oh, this is really rich and wealthy to be able to do this kind of thing."

Xiao Nan's arrangement can be called a lore, but in his opinion, it is no different from a little girl's temper.

You must know that the so-called threat is to make the enemy restrain his hands and feet and dare not act against himself.

Threatening yourself with death, haven't you considered that you are not afraid of death at all?

That is, the leader of the Xiao organization is lucky, and Orochimaru-sama does not intend to let himself exchange one with him, otherwise, after he poisons Nagato, these arrangements will become child's play.

Seeing the pharmacist's attitude, a trace of anger flashed in his eyes, and he wanted to say something more, but saw the other party waving his hand,

"After gossiping, if we waste our energy on intrigue with you, the success or failure of this operation is not guaranteed."

"Humph!"

Xiao Nan heard the threat in it, and he was even more dissatisfied in his heart, but in this situation, it was not the time to lose his temper.

The door of the Black Tower suddenly opened, Xiao Nan floated away, leading the way in front, and Yao Shidou followed behind unhurriedly, his attitude was very calm and calm, and he did not pay attention to the dangers around him at all.

After walking in the passage for a while, the two came to the patient this time.

On the wooden bed, Nagato still looked as thin and haggard as he had seen before, but his body was much cleaner, and he had obviously cleaned up the inside and outside of his body as Yakushidou had reminded before.

"You're doing a good job, but it's a pity that you can't miss a single one of the effort."

A hint of strangeness flashed in the eyes of the medicine master, but it was just an instantaneous change, and the control of the body was already different from that of a human hand, and it was controlled by the Great Snake Pill.

Slowly, he took out a bottle of reagent from the scroll, handed it to Xiao Nan, and said, "Take this thing

Give him a drink."

"What is this?"

Xiao Nan only glanced at it, then showed a vigilant look on his face, and said in a deep voice, "Why is this thing not on the list reported before?"

Xiao Nan is just a ninja and knows very little about scientific research and medical knowledge, but as the big steward of the Xiao Organization, she knows many people, and among these people, such as Shennong and Huangquan Sect Leader, they are all knowledgeable, at least there is no difficulty in checking and helping to identify.

The whole process of the pharmacist pocket for the operation had already been handed over to Xiao Nan, and she divided it into several parts, and asked different people about the problems in the process, striving to be harmless.

After Yahiko's death, Nagato's safety is almost all that Konan has, and no matter how much effort she makes, she won't let Nagato have any problems.

Right now, the pharmacist suddenly took out an unknown solvent, if he didn't say one, two, three, it would be forcible, and Xiao Nan would also stop the operation.

"This one."

Orochimaru smiled strangely, "It's a bottle of poison."

"What are you talking about?" Xiao Nan changed color and was about to shoot on the spot, but Nagato was calmer and stopped Xiao Nan.

"Yakushidou, don't make such jokes." Nagato stared at the white-haired young man in front of him and said in a deep voice, "Maybe Xiao Nan is too wary of you and makes you very dissatisfied, but this kind of joke is still too much."

"Joke, you're mistaken."

Orochimaru smiled and said lightly, "This is indeed a bottle of poison."

Nagato frowned, "What do you mean by that?"

If it is said that there is a deliberate harm, this is too open, but if there is no evil intention, poison ...... What does it mean to let him drink a bottle of poison?

"As far as I know, you've been paralyzed in bed for at least seven or eight years."

Orochimaru glanced Nagato up and down, his eyes narrowed slightly, "You have the bloodline of the Uzumaki clan, and it stands to reason that you have already recovered from that injury, but you just got this look, there is obviously something else in this."

According to the god of lights, Nagato's fall to this state was caused by the burden of the Outer Path Golem.

Ever since he channeled that monster in order to fight the enemy, he himself seemed to bear a curse, and his vitality was instinctively squeezed by the outer golems all the time.

At this time, after a careful face-to-face investigation, Orochimaru found that it was not only the Outer Dao Golem, but perhaps the reincarnation eye itself was also a big burden, and under the effect of the two phases, Nagato fell into this situation.

Hitomi Ninja's eyes are indeed a powerful weapon, but these Kui treasures also need to be maintained continuously.

There are so many people who have opened their kaleidoscope writing wheels in the history of the Uchiha clan, and the reason why they have not been passed down from generation to generation is because it is too difficult to nourish.

If it is also the holder of the Kaleidoscope Writing Wheel Eye, there is still a few chances, and ordinary Uchiha can only watch it rot away.

Kaleidoscope writing wheel eyes are like this, not to mention reincarnation eyes.

Madara Uchiha was able to find Nagato in the vast sea of people in the ninja world, which was a fluke.

But even so, Nagato was unable to fully exert the ability of the eye of reincarnation, and on the contrary, he also endured a lot of burden.

Hearing "Yakushi Dou" say this, both Xiaonan and Nagato's faces changed, and the latter took a deep look at "Yakushi Dou",

"You've got good eyesight, but what does that have to do with getting me to drink this bottle of poison?"

Orochimaru said slowly, "You have been sick for too long, and the injuries on your body have already become stubborn diseases, and if you don't take some fierce medicine to stimulate you, there is no chance of healing at all."

"I asked you to have surgery, not for you to treat me." Nagato shook his head, disapproving.

"If it weren't for the surgery, I wouldn't have bothered myself."

Orochimaru shrugged his shoulders and smiled, "White Absolute Cells have a life force that passively stimulates cell proliferation."

"If you leave it alone, you don't know what your lower body will look like...... Well, it wouldn't be a normal humanoid anyway."

As soon as these words came out, Xiao Nan's face was a little hesitant.

Even if Nagato really looks weird, she won't dislike the other party, but since she can avoid it in advance, why let the mistake be magnified.

"In that case."

Nagato's eyes fell on the bottle of reagent and he said, "Then I'll drink it."

After making up his mind, both Nagato and Xiaonan did things very simply.

The latter took the reagent from the "Yakushidou" and drank it in small sips.

Seeing Nagato swallow all the reagents, a wicked smile suddenly appeared on Orochimaru's face, "Oops, you guys have been fooled, this bottle is really just poison."

Almost as soon as Orochimaru finished speaking, Nagato suddenly slapped his throat with both hands and let out a whimpering scream.

"Nagato!"

Xiao Nan was so anxious that he exhaled a few times, and seeing that Nagato was just screaming and not having any other reaction, his anxious color suddenly turned to a fierce color.

"Yakushidou, you guy!"

The stone slabs on the wall were pressed over layer by layer, and this equivalent detonation talisman array could not be avoided at all, even if the Great Snake Pill clone was here, if he was not careful, he might be blown up.

But under these circumstances, Orochimaru's face remained unchanged, with a smile on his face, and he said lightly, "Don't be in a hurry, do you want to save Nagato?"

The detonation charm suddenly stopped around the pharmacist's pocket, and Xiao Nan reacted quickly, staring at the culprit angrily, and said sharply, "You want to blackmail me? I'm not going to give you this chance, either hand over the antidote or die together!"

"That's not what I meant."

Orochimaru pointed in the direction of the wooden bed and said with a smile, "Anyway, you wait a while, anyway, in this case, I can't run."

Xiao Nan will be suspicious, his eyes will stare at Orochimaru without blinking for a moment, and once he sees any movement from him, he will not hesitate to make a move.

But she apparently didn't have that chance, because in a few moments, Nagato stopped screaming and grabbed her with one hand.

"Nagato?" Xiao Nan's anger immediately dissipated, and he looked at Nagato worriedly, "Are you okay?"

"It's still a little uncomfortable, but it's okay to think about it."

Nagato said, turning his gaze to the "Yakushidou" who was heavily surrounded, and said in a deep voice, "Why are you making such a joke?"

If Xiao Nan cares, it will be chaotic, and he will make a decisive move, and it will not end well now.

"It's not a joke, it's a warning."

Orochimaru licked his lips, his eyes narrowed slightly, revealing a hint of danger,

"I just want to tell you that it's a real poison, and I can trick you into drinking it if I want to."

"You?!" Xiao Nan glared at Orochimaru, his face angry.

At this time, she also reacted, Nagato has been sick for a long time, it is true that she has accumulated diseases, and it is also true that she needs to be stimulated by toxic drugs, and the reaction just now is probably a normal stimulation reaction.

But whether the other party said that sentence or not, when she saw Nagato's appearance, she would probably be suspicious, and if it weren't for Nagato's quick recovery this time, she would probably have done it now.

"During the operation, you will experience ten or a hundred times more pain than you just did."

Orochimaru glanced at Xiao Nan, who was expressionless, and said lightly,

"There are certain risks associated with normal surgery, and if there is a bomb that will explode at any time, then there is no need for this operation to continue."

Even if it is to get enough experimental data, Orochimaru will try his best to ensure that the operation continues normally.

But Xiao Nan's connection with Nagato is too close, looking at the surrounding arrangement, there is a strong self-destruction plot, if the situation is a little more dangerous, she may drag both sides to die together.

This is unacceptable to Orochimaru.

Nagato was slightly silent when he heard Yakushidou say this.

In all fairness, he knew that Yakushidou was right, but in any case, everything Xiao Nan did was for his good, and Nagato would never reprimand the other party for this.

"I know we don't have some trust in each other."

Orochimaru moved his slender ten fingers and smiled, "But since I have been asked to operate on you, even if we pretend to be each other before, it's best to keep some trust."

"Otherwise, the surgery that could have been successful would have failed because of some people......

"No more." Xiao Nan interrupted Orochimaru's cynicism and said in a cold voice, "You just have to do your surgery, and I will ensure maximum restraint."

"I won't make a move on you until Nagato's death is confirmed."

"But if you really die because of the operation...... Xiao Nan stared coldly at the "Yakushi Dou", "No matter where you go, I will definitely solve you."

"That's terrible." Orochimaru shrugged, "I'll do my best not to mess with a crazy woman."

As he spoke, ignoring the anger that rose on Xiao Nan's face, he took out another bottle of solution from the scroll and handed it over with a smile,

"The poison has already stimulated the body, and I will drink it later when I straighten your bones and correct the crooked muscles, so as to nourish the body and replenish the body's consumption."

Unlike the previous bottle, this one is the chronic poison that Orochimaru made to get rid of Tsunade.

It slowly erodes the bones of the drinker, causing it to become brittle and take a long time to recover.

Although the flesh and blood of the Uzumaki clan contain surging vitality, ordinary sword slashes and even organic injuries are not a major problem, but the bones inside are not among them.

Moreover, no matter whether the effect of this poison is strong or weak, it will not affect my transplant operation.
