Chapter 914: Ninjutsu Hall

Taking the key from the gatekeeper ninja on the left, Osaimaru came to the door.
Insert the key into the keyhole, and a slight chakra light suddenly appeared. Around the keyhole, "Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, and Hai" appeared. Two different symbols represent twelve types of Jieyin.
Dashemaru's gaze moved lightly. This is the "coded lock" left during the design. In addition to the key, the door must be opened in conjunction with the jiuyin that changes every period of time.
Da She Wan calculated in a low voice, a series of formulas flashed through his mind, his eyes were extremely solemn. After using the key to activate the portal, this special ninjutsu mechanism must be unlocked within ten seconds, otherwise the enchantment will be triggered automatically.
Fortunately, Oshe Maru was very well prepared, although it was not possible to directly get the seal of the unlocking mechanism, but it also knew the algorithm in Hokage's confidential documents.
There is a saying that scientists are all mathematicians. In this world, there is no such thing as a scientist, but everything is always the same. No one can surpass Konoha in terms of mathematics.
Based on the year and time, and even the last used knot printing, Dashemaru calculated what she needed in just five seconds, and her hands quickly knotted.
As the hands changed, the symbols representing Jieyin lit up with each other, followed by a slight rumbling, and the door opened to both sides.
The corner of Da She Wan's mouth was slightly raised, revealing a slightly sullen smile, then he pulled out the key and threw it back to the unconscious Shang Nin, and strode into the building.
The door behind him is closed, and the building is very bright. It has already been switched to electricity, and it is easy to walk towards the distant stairs.
Ninjas have an extraordinary obsession with building underground bases. Even the secret rooms for storing ninjutsu like to be placed underground. This habit has continued from the Warring States Period to today.
Oshemaru knows that the underground of this building is divided into three levels, the lower the level of ninjutsu, the higher the level of ninjutsu, corresponding to the b-level, a-level, s-level, and three types of ninjutsu. As for the stronger ninjutsu, It is impossible to save it here.
After entering the first underground level, Dashemaru glanced at it. This level is the largest, at least several hundred square meters. It collects most of Konoha's b-level ninjutsu. As long as the name can be called, basically Can be found here.
He still remembers that the first time he chose ninjutsu here was after completing the mission of Iwanin Village. The reward of the mission at that time allowed him to choose an s-level ninjutsu, which he exchanged for two types of a-level ninjutsu. Opportunities for ninjutsu and three b-tier ninjutsu. On the contrary, both Jiraiya and Tsunade chose an S-rank ninjutsu.
There are too many ninjutsu here, it is almost impossible to copy in one night, and he himself does not have the special blood inheritance limit of writing round eyes, even if the memory is fast, he can’t remember it, so he quickly selected some he wanted to check beforehand. The ninjutsu memory, and copy some of the most needed ninjutsu.
Walking to the center, he then picked up a scroll with the three characters "Rashomon" written on it.
Da She Maru opened it without hesitation and quickly read it.
"Rashomon" is a kind of ninjutsu unique to the Thousands of Hands. It can be regarded as a powerful high-end ninjutsu. It is powerful and can be attacked and defended. It uses spiritism to summon huge Yama portals. At first, only one can be summoned. It was the original b-level ninjutsu.
With the improvement of Chakra and control skills, portals that can be summoned are also competing. For example, the "Triple Rashomon" is already a very strong type of A-level ninjutsu. As for the stronger "Five Rashomon", it is undoubtedly s-level ninjutsu.
But no matter what, the foundation is "Rashomon", the only difference lies in the strength and control of the caster himself.
According to Dashemaru, the highest number of this trick has appeared in the "Nine-fold Rashomon". It is said that the legendary first generation of Naruto can be used. The chakra required is an astronomical number, so it is not used many times, and its power can even surpass the Uranus. Surgery.
Ninjutsu that can be upgraded like this is naturally a rare species, Oshemaru quickly remembered, and then turned to look for other ninjutsu, while opening the memory, while using ninjutsu to expand the seal.
Silently calculating the time, about thirty minutes later, Oshemaru stopped the movement in his hand. Within such a long time, he recorded a total of 47 different b-level ninjutsu, which is extremely fast, but with Compared with all the ninjutsu recorded on this level, it is undoubtedly a drop in the bucket.
He has no nostalgia, and quickly moves to the next level. B-level ninjutsu is the introduction to advanced ninjutsu, and it is the most commonly used ninjutsu for most upper ninjutsu. Many stronger ninjutsu are developed on this basis. Then, if the time is enough, Dashemaru is happy to write down more.
It's a pity that time is limited tonight. He must set aside enough time to write down the a-level and s-level ninjutsu behind, and also allow enough time to leave.
Inside the ninjutsu secret room, there are no enchantments or traps. After all, being able to enter under such tight protection is enough to show that it is his own person, and there is no need to do anything more inside.
Going down to the second level, Oshe Maru quickly picked it up. This level is obviously much smaller than the previous level, even one-tenth the size. The recorded ninjutsu is even rarer, and it’s not bad if there are hundreds of them. .
Five types of ninjutsu each chose two, and he did not hesitate to continue to the lower level.
In his calculations, he has two hours. The first layer consumes half an hour, but the second layer only consumes ten minutes. The rest of the time has to record the third layer of s-level ninjutsu. After all, those only This is the real purpose of this visit.
The area of ​​the third floor is very small, only the size of a small house, built with three rows of stone platforms, each row has ten, and each stone platform is placed with an S-level ninjutsu scroll.
Da She Maru's eyes flashed frantically, and he clenched subconsciously with one hand. For him, these were rare "truths".
His gaze swept across the whole room, suddenly, he felt something wrong, as if there was something he had overlooked.
He turned his gaze fiercely, and saw a figure covered in black robe standing quietly in the middle of the room, looking at him with a playful look.

ps: I tried to resume the update. Apart from being a little uncomfortable, I feel better. ..
