Not to mention what Senju Tobirama would encounter when he went out to investigate the information, on the other hand, after two days of waiting, Yukimura finally ushered in the time to transplant the curse seal himself.

Early in the morning of the fourth day, before I had time to have breakfast, several ninjas took Yukimura to the laboratory of the Biology Department of the Research Department.

"Master Yukimura."

Here, Yukimura also met an acquaintance whom he had met before.

"It's you?"

Yukimura looked at the girl in front of her and said in surprise that the person in front of her was nothing but the first Yuki Mizuno whom he woke up after he came to Izumo Castle.

"Are you a member of the Science and Technology Research Department?"

"That's right."

Yuki Mizuno responded with a smile. She was wearing a white robe and stood among a pair of medical staff, vaguely respecting her. This situation made Yukimura know that her identity was extraordinary at once, not what she had guessed before.

It's as simple as an ordinary doctor.

"In fact, you and I may have some small relationship."

She said with a smile.

"I heard that my ancestors were the assistants of the fifth generation of Lord Naruto. Lord Yukimura should be familiar with him, right?"

"Master's assistant?"

Yukimura's heart thumped, and a figure suddenly appeared in his mind.

"Senior Sister Jing?"

In this way, he is another descendant of an acquaintance.

"Yes, my current job is the same as my ancestors, and I am an assistant and the first medical officer under Lord Sana."

"I see."

Yukimura nodded and glanced at the side. Unlike what he expected, Orochimaru was not here.

"Honor Naruto is busy with business and has a lot of work to do, so we will have you perform your surgery today. Please rest assured that we have performed similar surgery hundreds of times, so there will definitely be no problem.

”

Perhaps seeing the doubt in Yukimura's eyes, Yuki Mizuno explained again that the curse seal transplant surgery is different from eye change. Although the preparation process is a bit complicated, if you look deeper, the difficulty of the latter is actually higher than the former.

.

Yukimura's eye replacement surgery was conducted by Orochimaru himself, because the operation was a little more difficult, and the importance of those eyes was the most precious weapon for the entire rebel army, so only Orochimaru could do it yourself.

Ensure there will be no errors during the process.

In comparison, the difficulty of cursive seals is not that great. After more than a hundred years of development, the technology of cursive seals has been completely popularized and standardized. As long as people in Izumo City have this.

The idea is that you have the opportunity to undergo testing and then transplant the curse seal. It can even be said that immortals are walking all over the ground, and ninjas are not as good as dogs.

If Yukimura was not really special, even Orochimaru did not need to do it in person to prepare the fusion agent, the medical department of Izumo Castle could directly take care of all the work.

"Hundreds of times..."

Upon hearing this, Yukimura couldn't help but sigh again. The magic that was once so tall and powerful is now so terrible.

"Then please."

As he said this, he entered the laboratory surrounded by several people.

This laboratory is located on the second floor of the Biology Department of the Science and Technology Research Department. It is not big, only about 200 square meters in size. However, although the sparrow is small, it can be seen from the outside, and there are various equipment displayed inside.

After entering the instrument, I found that there were more things inside than I thought.

In the middle is the test bed, and on both sides are instruments of different styles and types and uses. Yukimura is also a medical ninja and is familiar with these things. However, he only knows some ventilators, shadowless lights, monitors, anesthesia machines, and blood.

There are many devices next to it that he can't name. Rows of reagents and injections of different colors are frozen in the medical freezer.

"Please lie on it first."

Yuki Mizuno turned on the shadowless light above and let Yukimura lie on the bed.

Before starting, she first explained some precautions.

"There may be a certain amount of repulsion during the operation. Although fusion agents and stabilizers can stabilize most adverse reactions, the erosion of the mark cannot be completely erased. Your cells and chakra will still be active.

Instinctively resist foreign grafts, so we need to first let you enter a deep anesthesia state, minimize the resistance, and allow your body to adapt to new forces in a sleep state, thereby reducing the possibility of backlash to

lowest."

"I see."

Yukimura recalled that he didn't feel anything wrong with it.

He knew that the curse seal was very aggressive. He had felt the most original curse seal from Shigego. Just a little bit of it made him completely lose his mind at that time, and Orochimaru's transformation

The Heavenly Mantra Seal and the Earth Mantra Seal will also erode the human body, so the sealing technique is needed to make the recipient's body fake death before it can be controlled.

Is this anesthesia process the same as fake death?

A lot of information about the curse seal suddenly appeared in his mind, and he roughly guessed the process of transplanting the curse seal.

“How long will it take?”

Before he started, he asked again.

"It won't take long, it will take about half an hour."

Yuki Mizuno said that she put on gloves and took out a sharp scalpel from the tray beside her. Then, Yukimura saw someone next to her holding an electric shock and tapping it on her arm.

The dizziness came in an instant, and he felt the darkness in front of him and no longer felt any more.

...

I don’t know how long it took, but when Yukimura regained consciousness again, the minute hand on the clock next to him had turned silently for a circle and a half.

"Is it over?"

He opened his eyes and the scenery in front of him was a little blurry. The bright light above his head was shaking, which made him feel dizzy, perhaps because of the light, or perhaps the anesthetics in his body had not yet effected.

"The surgery process is over."

A figure flashed in front of him, Yuki Mizuno and several researchers immediately appeared in front of him and asked with concern.

"How are you feeling now?"

"Feel……"

Yukimura sat up from the operating bed, looked at the dragon-shaped tattoo-like curse on his abdomen, first felt his physical condition in peace, then frowned and said.

"I feel a little heavy."

He slowly stood up, stumbled and took a few steps, then stood up and looked at his body again.

After coming to this world, after years of training, Yukimura had already trained his chakra to a state of being able to move his mind at will. Under normal circumstances, he did not need to control it deliberately. He could use the chakra at any time while sitting, lying and walking.

But now, after the operation, the control process has become much awkward, and calling chakra is not as smooth as before, as if something is preventing oneself from running chakra.

“This is normal.”

After listening to his description, several researchers were not surprised because the same situation had happened countless times.

"After all, the curse seal is an external substance. Even if there is no strong backlash, your body will instinctively reject them. You need to wait until your body fully adapts before this situation will disappear."

Yuki Mizuno explained.

"Depending on the ninja's own physical condition, this process usually lasts for a period of time, but you are also a medical ninja and have stronger control over chakra than ordinary people, so the impact should not be too great."

“That’s true.”

Yukimura tried again, and his frown brows stretched out.

Indeed, although the operation of chakra has been hindered to a certain extent, the impact is not great. After all, chakra's control is his specialty. Even if it is hindered, it will not completely affect its use.

Next, as long as you focus on practicing in this aspect, you should be able to eliminate this side effect.

"Is this a success?"

He looked to the side.

“It’s not entirely certain yet.”

Yuki Mizuno sat next to him, observing the feedback in Yukimura's body with the instrument, and answered.

"As for now, the transplantation process of the curse seal has been completed, and there is no strong backlash reaction, which means that the transplantation work of the first part has been successful."

"However, it is not yet certain whether it can be successfully synthesized chakra."

She said that the first phase was over, and the second phase was just beginning now.

The purpose of the mantra seal is to be able to use immortal arts more easily. Although the mantra seal is the main body, immortal arts are the most important thing. Yukimura's body has now endured the influence of the mantra seal. The next step is to start immortality.

Practice of art.

"Unlike the earliest spell seal, in order to reduce the danger, the latest spell seal is no longer the passive type of operation in the past, but is actively opened and interrupted by the user."

Yuki Mizuno said that the earliest mantra seal was developed by Orochimaru directly extracting Shigego's body cells. These two mantra seals will echo the user's emotions, even if the user does not deliberately.

To control it, it can also absorb natural energy by itself and force the user to enter the semi-immortal state.
