Shirou Emiya's Last Testament to the World

The Land of Rivers.

In the eerie Underground Fortress.

A long row of candles illuminated the corridor.

A long-haired man dressed in Cloud Pattern Black Robe stretched out his pale hand and stroked a candle flame by the corridor, a sinister smile playing on his lips.

Rumble

A tremor came from underground.

A Secret Chamber slowly opened in front of the long-haired man.

The scene inside this Secret Chamber was somewhat eerie and unsettling, as a beautifully crafted Crystal Coffin was placed in the center of the Secret Chamber.

Half a corpse was placed inside the Crystal Coffin.

If you look through the transparent Crystal Coffin, you can even clearly see the human organs of the corpse, making it look like a human specimen for medical study.

A young man wearing a hood stood in front of the Crystal Coffin.

The young man, wearing glasses, admired the Crystal Coffin in front of him, his eyes filled with an irrepressible fascination, as if the Crystal Coffin was an extremely exquisite work of art in his eyes. So much so that he was still somewhat reluctant to leave when he heard the door to the Secret Chamber open.

"Pocket."

The long-haired man entered the Secret Chamber, his smile softening into a slightly pleased expression. He greeted him slowly and deliberately, "It seems you quite like my collection—."

"Lord Orochimaru."

The young man turned around, bowed his head respectfully, and apologized. "I'm sorry, Lord Orochimaru, I was a little too engrossed in what I was watching—"

The young man's name was Yakushi Kabuto.

As Orochimaru's subordinate, Yakushi Kabuto understood his superior.

This official was very tolerant of his subordinates and did not care about their offenses, as long as they could complete the orders he gave.

This does not mean that Orochimaru is a kind person.

As a notorious S-Rank Missing-nin in the Shinobi World, Orochimaru judged his subordinates as if they were tools to be used or discarded at any time.

Orochimaru only cares whether the other person is useful.

If the other person is useless, Orochimaru will use them as experimental subjects to make them as useful as possible. If they are really useless, then he'll make them useful in the next life.

If the other party is very useful.

Orochimaru's attitude would be exceptionally kind, even warm, as if he were treating his own child; he was always like that.

"Alright, Kabuto."

Orochimaru was remarkably magnanimous towards Yakushi Kabuto, whom he considered extremely useful, even chuckling as he offered to explain on Kabuto's behalf, "I understand your obsession—."

"After all"

"This is the first human specimen to appear in the Shinobi World."

"The first medical ninja to appear in the Shinobi World, and the first medical research human specimen was created using his own body as the material."

We can even glimpse the profound thoughts of this ninja from a thousand years ago before his death through the half-body remains in the Crystal Coffin."

Orochimaru slowly approached the Crystal Coffin before him, a look of fascination in his eyes. "Even for me, every time I see this precious collection, I am filled with awe at this masterpiece that has been passed down for thousands of years. How much more so for you medical ninjas?"

"From the perspective of you medical ninjas..."

"Perhaps this man's status is comparable to that of the Sage of Six Paths."

"Yes."

Yakushi Kabuto stood beside Orochimaru, his eyes fixed intently on the half-corpse in the Crystal Coffin, and began to recount the story he had heard since childhood.

"Shirou Emiya".

"He pioneered the concept of medical ninjas."

"The first to establish Medical Ninjutsu system that spanned a thousand years."

"Legend has it that his medical skills are superb—"

Yakushi Kabuto intently at the Crystal Coffin, his steps unconsciously slowing as he moved forward. "In his hands, no matter how serious the illness, it can be cured."

"Legend has it that he was of noble character—"

"He has cured more patients than an entire country."

"In the final moments of his life, in order to dispel the prejudice of the Shinobi World against surgical dissection for treating diseases, and to make it easier for future generations to learn medical skills, he asked a friend to cut his body in two and make it into two human specimens sealed in Crystal Coffin."

"What a great person!"

Yakushi Kabuto reached out and stroked the patterns on the Crystal Coffin, recounting the words the Orphanage director who had adopted him often spoke when he was a child, "Medical ninjas are those who endure suffering that others cannot bear, to help those born into suffering."

It is precisely because of Shirou Emiya's noble definition of medical ninjas that ninjas have been willing to protect medical ninjas even during the bloody and cruel Shinobi World War, no one was willing to kill medical ninjas from enemy villages indiscriminately."

Yakushi Kabuto felt a little ashamed after he finished speaking.

In fact, he is skilled in Medical Ninjutsu, even more so than most people in the Shinobi World, but his moral character is hardly noble.

However, Yakushi Kabuto's guilt was only fleeting.

In this bewildering Shinobi World, everyone seems to seek nothing more than revenge, bloodshed, and the pursuit of profit.

Even Princess Tsunade in the world, wouldn't dare to call herself noble, let alone an ordinary medical ninja like myself.

"Speaking of which..."

"I never thought of that—"

"Lord Orochimaru actually has a Crystal Coffin in his hand—"

Yakushi Kabuto recalled the legend of the two Crystal Coffin and inquired about their origin, "Legend has it that the Crystal Coffin that these medical ninjas dreamed of disappeared long ago. One of them ended up in the hands of the Second Hokage Tobirama Senju, Tobirama Senju, which later triggered the First Shinobi World War. Fortunately, the person inside the Crystal Coffin quelled the war—"

"Yes-"

"I'm also curious about the existence of that Crystal Coffin."

"Unfortunately, I was born too late, so I can only get this one."

Orochimaru shook his head, a hint of nostalgia in his eyes. "This Crystal Coffin was sealed in the Shikkotsu Forest for a long time, and later it was given to Tsunade—."

"I see."

Yakushi Kabuto suddenly realized.

The most skilled medical Summoning Beast in the Shinobi World is the master of Shikkotsu Forest.

The first medical ninja in the Shinobi World back then would definitely have received Summoning Contract, and before his death, he left his own cadaver specimen to his partner.

That virtuous Lord Shirou will surely entrust the transfer of the remains to a future genius skilled in Medical Ninjutsu.

Without a doubt.

The most powerful medical ninja in the world today is Tsunade.

Since Tsunade, Orochimaru, Jiraiya were once the Konoha's Sannin, Yakushi Kabuto also knew some things about Tsunade's power of self-destruction, which had shone brightly in the war.

"Lady Tsunade— "

Yakushi Kabuto expressed his understanding and highly praised Tsunade's medical skills, "If it's Lady Tsunade, then this artifact is indeed worthy of being entrusted to her."

"Hehe."

Orochimaru's lips curled into a mocking smile as he slowly shook his head, saying, "This artifact won't help Tsunade at all; it'll only make her more dejected."

"For Tsunade— "

"This Crystal Coffin shouldn't have been there in the first place."

Orochimaru sighed, seemingly with some helplessness, and said, "Because Tsunade saw the real Shirou Emiya when she was young, and also received his guidance. Seeing such amazing humans can always make one lose their way, and Tsunade—."

"!"

The Yakushi Kabuto's expression became extremely complicated.

"The Second Hokage, Tobirama Senju."

"That ninja who is most skilled at developing dangerous forbidden techniques in the Shinobi World."

"After the final battle Hashirama Senju the First Hokage and his nemesis Madara Uchiha, the First Hokage, Hashirama Senju, defeated his destined rival Madara Uchiha, but in doing so, he suffered a severe injury that shortened his lifespan."

Orochimaru placed his hand on the Crystal Coffin, revealing the secret. "To heal the First Hokage..."

The Second Hokage used a forbidden technique called Impure World Reincarnation and another half of the body to revive this greatest medical ninja.

"That battle"

"This is also the biggest crisis since the founding of Konoha Village."

"The First Hokage, Hashirama Senju, defeated his friend and rival Madara Uchiha, but was also seriously injured at that time, and there was no one who could heal him."

"In order to heal his brother, the Second Hokage Tobirama Senju shattered the precious Crystal Coffin and used forbidden techniques and half of the body to revive Shirou Emiya from a thousand years ago."

"Tsunade mentioned it more than once."

"Actually, she met Shirou Emiya when she was a child."

"Perhaps I could say that I may have met the other person before."

Orochimaru's eyes narrowed as he recalled the silhouette he had seen in the sunset during his childhood, "That person, it must be him—."

"That's really something."

Yakushi Kabuto's tone held a hint of jealous envy as he sighed, "To be able to meet the first medical ninja in the Shinobi World, what an enviable past—"

"Yes-"

Orochimaru glanced at Yakushi Kabuto with satisfaction and continued, "But there's no need to be envious, because we've had the chance to see him today too—"

"Tsunade obtained this Crystal Coffin [someone's] hands, and left it behind Konoha when she left to travel—"

Before leaving Konoha

"I took this precious artifact with me."

Orochimaru reached out and stroked the patterns on the Crystal Coffin, praising softly, "Shirou Emiya, what an amazing human being. Even after a thousand years, I can still feel how intelligent he was. His knowledge is still useful today."

"Could it be—"

Yakushi Kabuto's gaze immediately fell upon the magnificent patterns on the Crystal Coffin. He adjusted his glasses and became curious about the mysteries contained within the Crystal Coffin.

"Are there any secrets hidden in the patterns on this?"

"Yes."

"Shirou Emiya left behind many ingenious ideas."

Unfortunately, Tsunade didn't discover the secret left behind by the great figure who had once guided her.

I discovered it when I was about to dissect the other person's body.

Orochimaru seemed very pleased with Yakushi Kabuto's attitude and didn't hesitate to share a secret spanning a thousand years. "If one has a sufficient understanding of human anatomy, under light sufficient for surgery, one can discover the code carved into the patterns on the Crystal Coffin. This code is the will left by Shirou Emiya to the medical ninjas of this world—"
