Reborn Naruto, I rolled my eyes to the sky

Before entering the Sand Village, I had already identified several targets that might help me find clues about the ancient city of Loulan.

The first is the library collection room in the Sand Village. Generally speaking, these places do not store ninjutsu and secret techniques, so the guards are not strict, but it is indeed possible to find the information I want.

The second is the Rei clan that founded the Sand Village. As a large clan that has been passed down from the Warring States Period to the present, they may also have news about the ancient city of Loulan.

There is also a little-known family, the Wind Clan. Although they currently have no presence in the Sand Village and there are no strong people in the clan, the history of the Wind Clan is even longer than that of the Fierce Clan.

The so-called century-old clans in the current ninja world are basically powerful families that have been passed down from the Warring States Period to the present. The most representative ones are the Senju clan, the Uchiha clan, the Hyuga clan, and the Kaguya clan, which are known as the four major families of the Warring States Period.

Among them, the Senju clan and the Uchiha clan are both descendants of the Six Paths Sage Otsutsuki Hagoromo, and have inherited the Six Paths Sage's sage body bloodline and sage eye bloodline respectively.

The Hyuga clan is the descendants of Otsutsuki Hamura who remained in the ninja world. They have completely inherited Hamura's sage body and sage eyes, which can also be said to be the Byakugan of the Otsutsuki clan.

Although it is not certain whether the Kaguya clan is the descendant of Ōtsutsuki Hagoromo or Ōtsutsuki Hamura, they undoubtedly have the blood of Ōtsutsuki Kaguya. In fact, compared to the descendants of Hagoromo and Hamura, the Kaguya clan, who possess the Shikotsu Kekkei Genkai, is closer to the image of Kaguya.

Apart from the ancient history before Princess Kaguya Ōtsutsuki came to Earth, these families can be said to be the most powerful and ancient families among the ninjas.

But in addition to these, there are many ninja families that may not be very strong but have a very long history. They are the disciples who followed the Six Paths Sage Otsutsuki Hagoromo when he was spreading the Ninja Sect he founded in the Ninja world.

Speaking of it, the chakra system and the practice method of the ninja sect are not the original practice system of the ninja world, but a power system that appeared after Kaguya Otsutsuki swallowed the fruit of the sacred tree and became the ancestor of chakra.

Afterwards, it was spread through the Ninja Sect of the Six Paths Sage and gradually became the mainstream practice method in the ninja world. Among them, the earliest disciples who followed the Six Paths Sage became the ancestors of various ninja families later.

This is the case with the Wind Clan. After the Six Paths Sage traveled to the Land of Wind, the ancestors of the Wind Clan had the good fortune to accept the Six Paths Sage's Ninja Sect inheritance, obtained the initial chakra seeds, and eventually formed the various ninja families in the Land of Wind.

After recalling several places where information about the ancient city of Loulan might be found, I sneaked towards the center of the Sand Village, preparing to search the village's library first.

Although I don't have a detailed map of the Sand Village, based on the layout of Konoha, the Hokage Building and various public facilities are located in the center of the village, so the layout of the Sand Village should not be much different.

With the insight of my Byakugan and the control of my body with my Gentle Fist, I sneaked safely from the outside of the Sand Village into the center of the village, and no ninja was able to detect my trace.

With Baiyan's perspective, finding the library among the many buildings was a natural thing. It was on the third floor of the Fengying Building, and there was not even a guard at the door.

But this is normal. At present, the inheritance of ninjutsu in the ninja world is mainly based on family inheritance and master-apprentice inheritance. Except for Konoha, the ninja schools in several other villages have just been established.

Apart from the basic Three Body Techniques and Five Elements Ninjutsu, the village's library does not contain any advanced ninjutsu or secret techniques. It is just some scattered historical records and anecdotes, so naturally it does not need to be guarded.

Of course, for me, I didn't come here for any secret ninjutsu, but I just needed to find information about the ancient city of Loulan in historical records and local legends.

As one of the five major ninja villages founded at a similar time to Konoha, the Sand Village has a history of nearly a hundred years since its establishment. Although the land in the Wind Country is barren, its area can be said to be the largest in the ninja world.

Therefore, there are quite a few miscellaneous books in the library of the Sand Village. In order to avoid missing out on the information about the ancient city of Loulan, I can only read them slowly one by one.

Fortunately, the Byakugan can see as clearly as day even in the dark, and can clearly see the contents of the book without the need for a light source. There is no need to light a lamp and risk being discovered by the Sand Ninja to check the contents of the book.

In my estimation, it would take two or three days to finish reading all the books here. Considering that Sand Ninjas might come here during the day, I can only check the books safely at night, so it would take even longer.

However, I have plenty of time to travel out of the village this time. As long as I can return to Konoha before the next Ninja World War, there will be no big problem. I think that even in the worst case scenario, there is more than enough time to travel to the Kingdom of Wind, the Kingdom of Demons and the three holy places.
