Rohan opened his eyes in a new world. As he observed his surroundings, he realized he was in the body of an infant who had just come into the world. In the last world he remembered, he had been a great all rounder scientist, working to make humankind invincible in the space. He had created inventions through the sheer power of his mind and research various space life and their bodies thus improving the life expectancy of humans.
The only thing he had truly liked in his last world was searching for truth, going outside, and learning everything he could. He was like a mad scientist who would do anything to complete his research.
At one stage, he had been working on creating a black neuton, life, and the creation of a black neuton itself. But a small accident occurred, and the particle collider exploded and he died.
And now, he had come here in the body of a child.
When he looked around, he found that the people here were not like the men from his previous world. Judging by their clothes and everything around him, it seemed like a medieval period of life. Humanity had not developed much in this world, and things appeared to be a little backward.
He listened to the voices of his parents, who were happy with his birth. He recognized some words that he had learned from their speech. His father mentioned the word "ninja" two or three times, and from that, he began forming an idea about the language. However, he would still need some time to fully learn and understand it.
Slowly, as days passed, he gathered more information from the conversations around him. Eventually, he discovered that he was in the Hidden Rock Village—in the ninja world.
With the passing of time, three years went by, and he was now three years old. By this point, he understood the basics of this world. According to the information he had gathered, this world mainly revolved around the profession of ninjas—fighting each other, killing each other, and living dangerous lives.
The First Ninja World War had already taken place, and now there were clear indications that a Second Ninja World War would soon break out. Everyone was preparing, and the entire village was tense, because they might have to face the strongest village in the world—Konohagakure. Just like the United States had been the greatest military power in his previous world, Konoha held that position here.
He also learned that there is a special power in this world known as Chakra, which grants supernatural abilities to the human body. People use it to perform various techniques involving fire, water, and other elements. For him, this world was like a treasure trove. As a scientist who loved exploring the unknown and uncovering deeply hidden truths, the existence of Chakra made him extremely excited.
He had already begun learning about Chakra from his parents. He was not trying to draw out Chakra within his own body yet—he knew he was still too young for that, and it could be harmful. Instead, he focused on studying its properties, how it flowed, and how it was used. He read as many books as he could find.
Like this, another six months passed.
And the Second Ninja World War began.
