"The mechanism setting, in many cases, uses the transmission of force to make the enemy's actions trigger a series of mechanisms in turn, and finally cause the effect we want. For example, this simple trap can hang enemies upside down from trees......"

On the podium, Sugimoto is holding a rope and demonstrating how to tie the knot, "In this way, if you step on it, the rope will be tightened, grabbing the enemy's foot, and the other end will also be tightened, thus hanging the enemy upside down to the tree......"

"The key principles and some of the key points of setting up the mechanism have been clearly explained," Sugimoto patted the stack of pamphlets on the podium, "This is a manual that specifically teaches you how to set up this mechanism, and the content in it is more specific, and you can take it back and study the settings yourself." The next time I go to class, I'll have to hand in the manual, and I'll test your ability to make a machine. ”

"Class."

"Aoyagi, Twilight, wait a minute, I've got something for you to see." Chisato looked mysterious and told them not to leave yet, but no matter how much they asked, Chisato just wouldn't say what it was.

When everyone else in the classroom was gone, Chisato took out a small scroll from his school bag, about the length of a palm, and a thick stick.

"Well, Aoyagi and Twilight, I found this in my family's storeroom yesterday. What do you think is written in this? ”

Unfold the scroll, the paper inside is yellowed, there are some numbers written on the paper, the font is too small, it looks very difficult:

96，9，26；88，4，5； 4，2，6；43，7， 4；68， 22， 6；

4，10，6；32，4，5； 75，3，4；56，7，3； 34，1，3……

"It's a code, Chisato. It has been taught in previous classes. The form of a group of three numbers is obviously to rely on a certain book to convert the text into three numbers: the number of pages, the number of lines and the number of columns, so as to achieve a secret code. Just make sure no one else knows which book you're using, and it's almost impossible for them to crack the code. It's a kind of code that has good confidentiality and doesn't need to be too brainless to design rules. Twilight looked at Chisato with some disdain in her eyes, "Have you forgotten all about it?" ”

"Hahaha, is that so?"

"Well, you see, there's the name of the book listed below, the Ninja Code." Twilight points to a few words at the bottom of the group of numbers.

Aoyagi was a little puzzled, why was the book used listed in the code? And it's a bit strange to use their textbooks to set up a code.

Chisato excitedly took out the "Ninja Code" from his schoolbag and began to read it against the code, while writing the deciphered words on a blank piece of paper. This should be the most serious time he reads a book.

"No, Twilight, what the hell is this?" Qianli held the blank paper in his hand and read: "If you feel it, you will be sad and forbearing, and you will ...... it when you are concerned."

Chisato looks at Twilight with suspicion, and says "Look, you can't do the same."

Annoyed, Twilight takes the Ninja Code and the scroll, "How is that possible, are you making a mistake?" I'll do it myself! ”

However, after he tried hard to decipher it, it was indeed a bunch of garbled characters.

Aoyagi is not very surprised by this kind of time-wasting behavior: "Forget it, if there is no corresponding book for this kind of code, it is impossible to solve it at all." Since Ninja Code isn't, let's not waste any more time. ”

Chisato muttered: "How can it be fake? It looks very old. ”

"Well, it's not like it's proven impossible to decipher this thing. We've already wasted a lot of time, so let's go and practice. ”

Chisato and Twilight are a little lost, thinking that they can find something interesting, maybe it will be a clue to a treasure?

………………

At night, Aoyagi stood in the moonlight of the courtyard, thinking.

It has been about three months since the tragedy of the Uchiha family, and not long ago, another batch of new students enrolled, which also means that Aoyagi has entered the fourth year of the ninja school, and there is not much time, so he must determine his development direction as soon as possible, so as to better arrange his cultivation plan and improve himself more efficiently.

Shuriken and kunai throwing, physical arts, ninjutsu, illusions, what should I specialize in?

Shuriken and kunai throwing, as long as they reach the level of universality, if you want to continue to improve, judging from your current talent in this area, the effort spent is not proportional to the gain. Moreover, shuriken and kunai are relatively weak in terms of destructive power after all. In front of the boss with various attacks and defenses exploding in the later stage, shuriken and kunai can only be used to harass many times.

As for physical skills, he can't compete with Li and Kaibi, and he can rely on physical skills alone to fight all over the world. For himself, physical skills can only be used as a conventional means, and if he wants to use it as a killer tool, he is still not powerful enough.

Illusions,The level of illusions related to the scrolls at home is relatively low.,Moreover,Unless it's a terrifying illusion of Tsukiyomi or Kurama Yakumo.,Other illusions.,More often than not, it's used as control.、Interference.,The lethality is still lacking.。

Then there's only ninjutsu.,There are many types of ninjutsu.,Various uses.,There's no lack of powerful existence.,I'll specialize in ninjutsu in the future.,Shuriken and body art are raised to a sufficient level.,If you still have leisure after practicing.,You can consider learning some illusion assistance.。

In addition, if there is a chance, immortal art must definitely be learned, and this method of greatly improving strength cannot be let go.

If you want to specialize in ninjutsu, you must not only learn a variety of ninjutsu, but also be able to use them skillfully, and preferably, be able to develop ninjutsu yourself. With a spiritual space, he may be able to use the knowledge of his previous life to develop a lot of powerful ninjutsu and improve his combat effectiveness.

Thinking of developing ninjutsu, Aoyagi recalled the materials he had seen in the space related to the twelve mudras. I used to be busy laying the groundwork, but now I can take some time to study it. If you can really figure out the meaning of each of the twelve mudras, it will be very helpful to develop ninjutsu on your own.

In addition, if you can figure out the various basic characteristics of chakra, you may be able to develop ninjutsu using various characteristics. Isn't the Spiral Pill a powerful ninjutsu developed by taking advantage of Chakra's form change?

Entering the spiritual space again, this time Aoyagi immediately walked to the bookshelf and found the information about the handprint, which he read and studied carefully.

After a few hours, he put down the book in his hand, a little excited.

After carefully reading the materials and researching and scrutinizing, he had a rough idea of what the twelve earthly branches represented.

The twelve earthly branches were originally used for timekeeping, such as the twelve hours in ancient Celestial Empire, which were named after each other, and the twelve zodiac signs each corresponded to an earthly branch.

In addition to timekeeping, the twelve earthly branches have other meanings, each corresponding to an organ. At the same time, the twelve earthly branches together represent the process of development of things (in the case of plant development), which is most likely related to the meaning of the mudra.

For example, the sub represents ......
