At Konoha, a sealed crystal coffin stands in the center of the dark underground secret room.

This crystal coffin is a bit strange. It has exquisite patterns painted on it, but there is only half a corpse inside.

If someone observes through the crystal coffin, they can even clearly see the human organs of the half-dead body inside, making it look like a human specimen for medical study.

This scene made the secret room look particularly strange.

The silver-haired man standing in the secret room had long been accustomed to this strange environment. His eyes were fixed on the crystal coffin in front of him, and his red pupils revealed cold decisiveness.

"Tobirama-sama."

A masked Anbu ninja walked in, dragging a tied-up ninja in his hand, and reported in a low voice: "In the past few days, many enemy ninjas have sneaked into the village to spy on the news. We searched the cells and found that the Sunagakure ninja who sneaked into the village last night has the largest Chakra reserve in the entire prison…"

"Brother's situation…"

When Tobirama was halfway through his speech, he realized that he was talking to his subordinates and changed his address: "How is Hokage-sama doing now?"

"Still receiving treatment."

The Anbu ninja said with some concern: "We have never seen Hokage-sama get injured so badly. Mito-sama said that it might endanger his life…"

Tobirama's expression suddenly turned ugly. He was silent for a while before he spoke again and asked: "Is there any unusual movement from the Uchiha Clan?"

"Not at this time."

The Anbu ninja shook his head slightly and continued: "Since the news that Madara Uchiha was killed by the Hokage came out yesterday, the ninjas around the Uchiha Clan have not found any other abnormalities except that they are a little scared…"

"Continue to monitor closely."

After giving the order, Tobirama Senju looked down at the tied-up Sunagakure ninja and said in a deep voice: "Ask the other Anbu teams to strengthen patrols in the village and assign a team to guard outside. No one is allowed to approach this forbidden room."

"Yes, Tobirama-sama!"

The Anbu ninja retreated hastily.

"Hmm…"

The Sunagakure ninja, who had been tied up tightly, whimpered and looked up at the silver-haired man, his face eager to say something.

"I know what you want to say."

"But I'm not interested in hearing your explanation."

Tobirama looked at the other party with disdain, as if he was looking at a dead person: "You sneaked in just to spy on the elder brother, or you just want to know the news that he and Madara died together…"

"Snort!"

"You better leave this kind of thing in your dreams."

Tobirama raised his head and looked at the crystal coffin in front of him as if he wanted to use this crystal coffin to prove something to those villains in the Shinobi World who wanted to challenge Konoha.

"This crystal coffin is the progenitor of medical ninjutsu for the entire Shinobi World."

"Shihara Emiya."

"You should have heard of this name."

The Sunagakure ninja looked at the crystal coffin with some surprise.

Shihara Emiya.

This name is truly well-known.

The entire Shinobi World knows about this saint who lived thousands of years ago. This saint created the concept of medical ninjutsu and even standardized the system of Medical Ninjas.

It is said that he never cared about the patient's identity when saving people; it is said that no matter how serious the disease was, he could cure it; it is said that he had saved more people than the entire country…

The most respected thing is…

The next event that happened when Shihara Emiya died was also awe-inspiring.

In order to pass down the medical ninjutsu of the Shinobi World, to make it easier for more people to learn medical skills, and to help the Shinobi World break down its prejudice against surgical dissection, Shihara Emiya had his body split into two crystal coffins before his death and left them to the Shinobi World.

Even during the turbulent Warring States Period thousands of years ago, when ninjas fought and destroyed each other, everyone tacitly agreed not to destroy Shihara Emiya's two crystal coffins.

Even most people in the Shinobi World have never seen it.

The Sunagakure ninja looked at the half-dead body in the crystal coffin, feeling a little surprised and respectful at one moment and a little uneasy at another moment.

People in the past…

What does it have to do with the present?

A Medical Ninja who has been dead for a thousand years, no matter how skilled he is, can't possibly be resurrected to help treat the first Hokage? Could it be that the crystal coffin contains the secret of medical ninjutsu?

"Our Senju clan has always been known for its expertise in Chakra control, and we are the ninjas in the Shinobi World who are most suitable for practicing medical ninjutsu."

"It is said that this crystal coffin containing the human specimen of Shihara Emiya was left to the ancestors of the Senju clan by his own words before his death…"

"Even though most people in the clan would not practice medical ninjutsu for the sake of fighting, they still regard this crystal coffin as the glory of the clan…"

Tobirama Senju narrowed his eyes, his fingers stroked the exquisite patterns on the crystal coffin, and his voice gradually lowered: "I never thought that one day I would destroy it with my own hands…"

The Sunagakure ninja showed a look of horror.

"But…"

"For my brother…"

"Everything is expendable!"

Tobirama Senju stared at the crystal coffin in front of him. A ray of Chakra light appeared on his palm, and he slapped the crystal coffin heavily!

Crash!

The crystal coffin suddenly shattered!

The half-body that had been lying inside fell out!

The Sunagakure ninja sitting on the ground stared at the half-corpse that fell to the ground. 

This scene was so horrifying that his eyes were instantly filled with fear!

"Only my eldest brother can guarantee the peace of Konoha…"

Tobirama quickly formed hand seals with his hands, and his voice was as calm as an ancient well: "Even if there is only a one in ten thousand chance, even if it means blaspheming the souls of the dead, I must do this…"

When he finished speaking, Tobirama slammed his palm heavily on the ground, and his voice suddenly became cold!

"Impure World Reincarnation Technique!"

A pitch-black spell appeared under the palm of Tobirama!

A series of spells quickly moved on the ground, forming two different barriers around the Sunagakure ninja and Shihara Emiya's half-body.

Under the horrified gaze of the Sunagakure ninja, half of Shihara Emiya's body turned into dust and ashes and floated up, slowly attaching to the body of the Sunagakure ninja!

The Sunagakure ninja felt an unprecedented sense of suffocation. The despair of being on the verge of death slowly filled his eyes with fear, and dust and ashes gradually covered his eyes…

Until the end… the body of this Sunagakure ninja was completely shrouded.

Tobirama stared at the figure that slowly emerged from the ashes, and the stone in his heart finally fell to the ground. 

At least, it seemed that his technique was successful.

The technique of Impure World Reincarnation is a Forbidden Jutsu.

This technique can summon the souls of the dead from the Pure Land to the human world by using the life of a living person and the bodies of a sufficient number of dead people as materials for the technique.

Under normal circumstances…

There is no way that Tobirama will have the chance to resurrect the dead from a thousand years ago.

Because no corpse could be preserved for more than a thousand years, especially during the chaotic Warring States Period, many corpses eventually became wandering ghosts in mass graves.

However, Shihara Emiya, the founder of medical ninjutsu, is an exception.

Because his body became a medical human specimen and was well preserved, Tobirama Senju got the opportunity to resurrect him through Impure World Reincarnation.
