It was close to ten o'clock in the evening, the Hokage Building.

An old man over half a hundred years old, wearing a Hokage hat, was sitting upright at his desk, smoking a cigarette while listening to the report of two members of the Shadow Division.

"That's how it happened."

Hinata finished speaking and bowed to the old man.

"Hokage-sama, do you need to gather a group of people from the shadows to arrest Orochimaru?"

“……”

The old man's expression was serious, but he didn't answer, just smoked in a muffled voice.

After a long time, he put down his pipe, his eyes blazing, "Xunyi, Kakashi, you should know the rules of the dark part...... Where is the intelligence of the mission? ”

"Hokage-sama, please rest assured."

Xun Yi took out the sealed scroll from his pocket.

"This is the scene of Orochimaru's crime, and I invite Hokage-sama to take a look."

"Hinata's sealing technique?" The three generations of Hokage glanced at it and nodded, "It's okay, let's release the information." ”

"Yes."

Seeking the order, he spread out the scroll.

Traces of black tadpoles can be seen all over it.

Immediately afterwards, Xunyi's hands quickly sealed, the blue tendons on his forehead burst out, and he opened his eyes again-

"White-eyed, solution!"

The next moment, a white light rose from the scroll, as if it had been induced, and the black tadpoles on the scroll began to wriggle, little by little, in the direction of the white light, converging towards the space in front of the three generations of Hokage. Kakashi's eyes widened for a moment, and he was surprised to see that these black tadpoles had gathered together, like particle beams, slowly condensing into a real scene.

Orochimaru's dissecting table, Orochimaru's face, female corpse on the dissecting table......

That's right, the scene is still three-dimensional, and if you look at it from Kakashi's line of sight, it's like you're there!

After a while, the scene was completely restored, including the blood on Orochimaru's gloves, the fluff on the female corpse's face, the number of bones on her body, and so on, all very clearly!

"It's incredible!"

Kakashi couldn't help but exclaim, and subconsciously stretched out his finger, wanting to touch the Orochimaru in the scene, but he passed through it and touched it empty.

"Stunned, this is the sealing technique of our Hyuga family." Hinata raised her eyebrows triumphantly.

"Well, ninjutsu is such a magical thing!" Kakashi sighed, at this moment he made a decision in his heart, decided to use the writing wheel eyes left by Obito to learn all the ninjutsu in the world as much as possible, and from the copying technique of the writing wheel eyes, he moved towards the three generations of Hokage-sama.

"Ahem......"

The old man's cough was heard on the side, interrupting the small talk between the two.

The three generations of Hokage looked at the projection in front of him, carefully confirmed it, and nodded: "The information seems to be true...... Xunyi, how long does this sealing technique last for you? According to Konoha's specific laws for ninjas, there is a time limit for special ninjutsu, and if you don't reach it, you can only give perjury. ”

"This ......" Xunyi hesitated for a moment, a little embarrassed, "Xunyi is not good at learning, and can only seal the content for five minutes." ”

"Five minutes......"

The three Hokage raised their pipes and stared at the scene in the image, silent.

After a while, he said to Kakashi on the side, "You go down first, I have something to say to Xunyi." ”

"Yes."

Kakashi nodded and exited the room.

After Kakashi left, Xun Yi looked a little anxious: "Hokage-sama, according to Konoha law, five minutes should be able to convict Orochimaru!" ”

"Not that problem."

The three Hokage shook his head and put down his pipe.

"Let's talk about Kakashi first...... What is his credentials as a shadow minister? ”

"Obey orders, act rationally, and can be contained." Xunyi didn't quite understand, but still replied.

"Oh...... So, what do you think of Orochimaru? The third Hokage tapped his pipe.

"Orochimaru? Villains who do all kinds of evil, many people have died at his hands. ”

"Really......"

The three Hokage took a puff of his cigarette and lowered his eyes, looking out the window.

It was already dark, the stars were dotting, and a cool breeze blew outside, blowing the old man's Hokage robe whirring, and the chill seeped in.

After a long time, the three generations of Hokage sighed.

"Or, gather ten members of the Shadow Department and go to the Hokage Building to stand by."

"Yes!"

……

As the night came, there were fewer and fewer people on Konoha Street, the shops closed one after another, and the lights of the surrounding homes dimmed, no longer bustling during the day. During the war, people need to rest and maintain sufficient physical strength, because they do not know when the enemy may enter the village, and they must always keep their spirits up, and have the strength to escape when necessary, leaving the incense for the next generation.

However, in a bleak residential area, there is a home, and the lights on the second floor are always on.

At this moment, Orochimaru is sitting in the study on the second floor, there is a large stack of books in front of the table, and you can see it according to the light, and the covers of the books are written "History of the Fire Country", "General History of the World", "Civilization and Origin", "Science", "Development of Physics", "Industrial Revolution", ......

And so on and so forth.

Orochimaru is reading at night, reading about the history of the development of this world civilization.

To be precise, "revisit".

It is true that Orochimaru is a person who loves to read, but his brain capacity is not unlimited. Orochimaru wants to learn all the knowledge in the world, he used to try to use biotechnology to stimulate the cerebral cortex, so that he can achieve the ability to "never forget", but unfortunately the final experiment proved that "forgetting" is actually a mechanism to protect the brain - to use the metaphor on the earth, the human brain is a "CPU", can never be overloaded, once it is really "unforgettable", the result is that after a few days, it can no longer absorb new knowledge.

However, after exercise, Orochimaru's brain can achieve "primary and secondary memory".

For example, divide the brain capacity into a column of bookshelves, and put the commonly used knowledge in the first shelf, the second shelf, and the third shelf...... And so on. He doesn't need to read books to remember the main knowledge, but the secondary knowledge needs to be "revisited", and the knowledge he has read before needs to be read again, and revisiting can help him pick up the knowledge.

Orochimaru is not interested in "history", so this time needs to be revisited.

According to the content of the revisit, he gradually remembered the history of the development of "civilization" in this world.

First of all, during the Warring States period, the science and technology of this world was already developing.

About 500 years before the establishment of Konoha was established, the concept of "electricity" appeared in the world, at that time human beings have completed the second stage of the "industrial revolution" similar to the earth, and entered the era of "electric", steam engines and internal combustion engines were invented one after another, the workshop handicraft industry gradually developed to the machine industry, the productivity was constantly developing, and the smelting technology of coal, iron and steel reached the stage of perfection of human beings.

Technology is advancing, and it seems to be a good thing.

But—

One day, a magical power appeared among human beings.

That kind of power, it's called "Chakra".
