Starting from Uchiha Obito

When each territory is first established, it will come with three basic buildings: a barracks, a warehouse, and a workshop. The barracks provide basic manpower, the warehouse provides basic material storage, and the workshop provides basic tool manufacturing. Of course, Wang Jie heard all this from other lords, and now he has begun to doubt the authenticity of this information.

"Why do I only have one building..." Looking at the only lonely building on this land after the establishment of the territory, Wang Jie felt like he was in a state of panic.

"Is this the price of living in hiding?" Wang Jiefei muttered to himself as he checked the properties of the building from above. And there was only one thing he muttered, because when he saw the name of the building, all his complaints disappeared.

Izanagi's Nest - Infuse chakra to create any type of soldier you want.

This is the system's introduction to this building. As for the detailed usage rules, such as how much chakra can be injected to generate how much flesh and blood, the hardness, and so on, it's too long to go into. In short, this is a universal manufacturing machine that can produce anything with enough chakra. Don't think that it is a manufacturing unit, but in fact, when DIY, you can choose a unit that is made of pure iron elements, in the shape of a block, and has no ability to move or think. What is the difference between this and a piece of iron?

There is no doubt that the function of such a building even surpasses some miracle buildings. Using one of it to exchange for three other rubbish basic buildings is simply a huge profit. As for why there is such a good thing... maybe this benefit comes from the gift of blood.

Sometimes, when Wang Jie was alone and in a daze, he also wondered where the power of the Sharingan came from? Otsutsuki? It was obvious that Otsutsuki's eyes were Byakugan, so the power of the Sharingan could only come from the sacred tree. It also made sense from the nature of the chakra. When Otsutsuki Hagoromo split up, the Yang escape technique belonged to Asura, the Senju lineage, and the Yin escape technique belonged to Indra, the Uchiha lineage. Yin escape chakra originally had the attribute of creation. As the ultimate bloodline of Yin escape chakra, it was not difficult to understand that the Sharingan, as the ultimate bloodline of Yin escape chakra, created a pupil technique according to the will of the heart at the moment when it was stimulated by a lot of spirit and opened the Mangekyo.

But that refers to other eye techniques, whether it is Amaterasu, Tsuki, Kagutsuchi, or Shisui's buggy Kotoamatsukami, they can actually be explained by this principle, because no matter how exaggerated the effects of their eye techniques are, from the perspective of energy consumption, they have not exceeded the limit of an extraordinary human being. But an infinite space? There are countless indestructible platforms in the space. Such material changes are a bit beyond Wang Jie's expenditure range. Even the current Wang Jie does not think he can afford the price of creating a divine space.

You have to know that the Shenwei Space has always existed. If it was really created by chakra, this kind of consumption would not be enough to kill Wang Jie.

So the ability of the eye technique Kamui can only be a key, and the Kamui space itself is already there, so the question is, if it already exists, how did it come into being? Where is it? Why does it exist? It can't really be for a desperate Uchiha child to have a place to hide and cry.

In the past, Wang Jie did not have a definite answer. The most he thought of was that perhaps the sacred tree absorbed the original gods of the Naruto world as nutrients, and the Kamui space should have originally belonged to one of the dead gods.

Now Wang Jie can basically confirm that the Kamui Space was once the territory of a powerful lord, and the Izanagi's Nest he obtained was a building that once existed in this territory. As for how the lord died that year, it is not known for the time being, but after his death, he turned into nutrients and was absorbed by the Otsutsuki sacred tree. Otsutsuki Kaguya, who ate the essence of the sacred tree, thus became connected to this territory, and then it was passed down from generation to generation through blood, and finally in Obito's hands, this authority to enter and exit the territory was activated in the form of eye techniques.

So Wang Jie would say that this should be a gift from blood. In fact, it is very reasonable to think about it. It is known that many things left over from ancient times on the territory of Dragon Kingdom belong to the category of equipment, and in the thousands of years in between, there are no records of the secret space or Pangu Continent. There are various myths, but there is no mention of any professions, leveling, or lords. It was not until the secret passage was opened again in the doomsday world and humans gained a foothold that they discovered that some of the previous antiques were actually very advanced equipment.

Then it is not surprising that the same thing happened in the Naruto world. The only difference is that the secret passage here has not been opened again, but there is the variable of Wang Jie, who brought the influence of the secret realm and Pangu Continent to the Naruto world. In this way, Orochimaru's Kusanagi sword that can be stretched and shortened and never broken is likely to be some high-level equipment, but the conditions for use may be relatively low, so Orochimaru can use it even if he has not become a professional.

The most crucial thing is that the historical blank period on both sides occurred 3000 years ago. The historical records of the doomsday world for nearly 3000 years are clear and compiled, while the records before that are vague. Even if there are texts left, they are regarded as supernatural novels by historians. The Naruto world is even worse. Even the mythology starts with the Six Paths Sage. There is no information about what the world was like before the Six Paths Sage, and not even an exaggerated and distorted myth story has been passed down.

Then something must have happened in the past three thousand years, causing the two worlds that were originally connected to the Pangu World to be completely disconnected, and the lord who was supposed to be immortal also died inexplicably. It was not until the two worlds were connected again that the past history came alive again.

There is also the most favorable evidence for this matter. The scope of civilization in Pangu World is such that, with the rate of the birth of a batch of lords every year, each lord's territory must cover at least 4 square kilometers. If Pangu Continent really existed from time immemorial, then its scope of civilization has long exceeded the scope that can be described by numbers. In fact, even the territory of the Heaven Force directly controlled by the God of Light is only tens of millions of square kilometers, and the United Empire of Lords where Elvin's territory is located is less than 3000 million square kilometers.

Of course, these are just two of the many forces, but it is obvious that this number does not match the eternal existence, so where did the previous territories go? It is impossible that the civilization history of Pangu World and Naruto World is only 3000 years old, so thousands of years ago, there must have been an accident that affected the entire Pangu World and other worlds including Pangu World, causing this civilization fault.
