Could it be that Konoha's ninjas found the passage to Earth, or similar to Thor's Bifrost Bridge, a transportation tool, they came to Earth and found Charles Doyle, nurturing him back into a ninja.
Or perhaps the Ninja World is closely connected to Earth, with many channels. After all, not only Konoha, but also Suna, Oto, Taki, and now the unexpectedly arrived Kabuto, clearly didn't use the same passage.
Thinking about the Ninja World being a world not much smaller than Earth, Coulson's first thought was about resources.
A planet almost the size of Earth, capable of sustaining life, what a tremendous number of resources it would have! If they could possess it, it would bring terrifying benefits to Earth.
But thinking about the terrifying power of ninjas, Coulson felt helpless. This benefit might not be obtainable after all, considering that behind the ninja villages, which they previously only saw as small villages, there is a country even larger than the United States.
All of this would require a new plan.
"Mr. Kabuto, could you please explain the relationship between the Five Great Nations and the five major ninja villages?"
Kabuto nodded and said, "Because the Uchiha and Senju clans established Konoha Village, ninjas from various countries sought to emulate it and established their own ninja villages."
"This transformed ninjas from a family-based form to a nation-based village system."
"The ninja village of the Fire Nation is Konohagakure, Wind Nation's is Sunagakure, Water Nation's is Kirigakure, Earth Nation's is Iwagakure, and Lightning Nation's is Kumogakure."
"Fire Nation: The gentle terrain of rolling hills covers the entire nation, making it a large country capable of supporting a vast population with abundant greenery. As it is located almost at the center of the Five Great Nations, it has historically been a vital transportation hub, contributing greatly to cultural exchange among nations. The vitality brought about by cultural exchange sustains the economy and prosperity of the Fire Nation."
"Wind Nation: Although Wind Nation has a vast territory, most of it is occupied by deserts. The rainfall is also sparse throughout the year. The citizens build villages in oases in the desert and reside there. Despite the harsh environment, the population is large, and trade with the Fire Nation is prevalent."
"Water Nation: Located in the outer sea, it is an island with a unique culture. Despite being surrounded by the sea, it has a special terrain with many mountains within its territory. In addition, the surrounding islands have different customs, and many islanders still adhere to their own traditions."
"Lightning Nation: The echoing thunder in the towering mountains is said to be the origin of this country's name. The rivers originating from the mountains in the central part of the peninsula, which splits it in half, create many winding coastlines where they meet the ocean, allowing people to see the majestic and beautiful sea. There are also many hot spring areas within the country."
"Earth Nation: Most of the country consists of barren rocky cliffs. The high mountains and rocks along the border block transportation between the Earth Nation and other countries. In addition, winds blowing from the north pass over the mountains and blow small rocks from the country into other countries, a natural phenomenon known as "rock rain," which is very famous."
"These are the Five Great Nations, with the Wind Nation occupying the largest area, but mostly filled with desert. The Fire Nation has the best environment and the strongest power."
"As for the five major ninja villages, I am just a wandering ninja, so I don't know much. I only have some understanding of common knowledge passed down among ninjas."
"Hidden Mist Village: Known as the mysterious ninja village locked in dense fog - located in the Water Nation."
"Hidden Rock Village: Surrounded by perilous terrain, known for its strong defense - located in the Earth Nation."
"Hidden Sand Village: A harsh environment where sandstorms rage, excellent for nurturing ninjas - located in the Wind Nation."
"Hidden Cloud Village: A powerful village standing tall beyond the sea of clouds - located in the Lightning Nation."
"As for other small countries and their ninja villages, I know even less and cannot provide much information."
Listening to Kabuto's explanation, Coulson was amazed. The reality was vastly different from their predictions, and their speculation about ninjas and ninja villages was like a blind man touching an elephant, with a staggering gap.
"The information you provided is already very helpful to us."
"Mr. Kabuto, now we need to return to the headquarters. On one hand, we need to process your employment documents, and on the other hand, we need to assess your strength to give you a rating."
Kabuto nodded. "Alright, I have no problem with that."
Kabuto then packed up the items on the table, closed the three boxes, and carried them all in his hands.
Coulson, seeing this, didn't say anything. These were all things he had promised in advance, so without delay, they left and headed towards the Triskelion.
On the way, the car raced ahead, and Coulson soon brought Kabuto to the headquarters of S.H.I.E.L.D.
Upon entering the building, agents quickly approached as Coulson had already notified S.H.I.E.L.D. headquarters in advance.
"Kabuto, follow this Agent to complete the employment procedures and undergo combat testing."
"I have some other work to attend to."
Hearing that Coulson handed him over to another agent, Kabuto didn't mind. Instead, he smiled gently and said, "Sure thing, Agent Coulson."
Watching Kabuto leave with the Agent, Coulson immediately headed towards Nick Fury's office.
Taking the elevator all the way, Coulson arrived at the top floor, Nick Fury's office, and knocked on the door.
"Director!"
Seeing Coulson enter, Nick Fury's face lit up with a smile.
"Coulson, you did well. You've brought us a ninja for S.H.I.E.L.D."
"It looks like your agent rank is going to be raised again."
Hearing Nick Fury's praise, Coulson's face didn't show the excitement of his impending promotion but remained serious.
"Director, based on the intelligence I obtained from Kabuto, many of our plans may have been wrong from the beginning."
Hearing Coulson's serious tone, Nick Fury's expression also changed. The smile disappeared from his face as he asked seriously,
"What intelligence?"
Coulson then recounted the intelligence he obtained from Kabuto about the Ninja World, the five major nations and villages to Fury.
As Coulson spoke, Nick Fury's expression became increasingly grim, his face devoid of any expression, as he continued to write on the paper in his hand.
The intelligence wasn't much, and Coulson soon finished recounting it.
After hearing Coulson's account, Nick Fury didn't immediately speak but continued writing. After a few minutes, he stopped and then looked at Coulson.
