(Chapter 61 added)

Although all of the above mentioned content is not taught in the ninja school today, Bandai Seihei sighed in his heart while studying: I really underestimate ninjas!

What is Ninja? In the Otherworld, they are magicians and warriors. But in essence, mages and warriors, as well as ninjas, are war machines against war, but mages and warriors mostly fight against Warcraft, while ninjas fight against humans. It's just that the world of magicians is always portrayed beautifully, and "Naruto" doesn't fully show that cruel side.

Moreover, Ninja Village is an organization supported by the power of the whole country, how can it be easy to become a member of such an organization, from a human to a non-human war machine? There are two keys to this, the first is "non-human", and the second is "war machine". There are too many factors that lead to the victory of a war, and if we don't say it, we will ask for peace.

The two sides are facing each other, how to make the opposing party's generals strong? Assassination Decapitation – Assassination skills are required. What if the two sides face each other and the enemy number more than us? Dividing them – requires tactics. What should I do if the two sides are facing each other and the enemy is not clear? Intelligence gathering – requires investigation, interrogation, tracking, counter-tracking.

A qualified ninja must take into account the ability of various war needs on the one hand, and on the other hand, he must reach non-human in terms of his own destructive power. It's not easy!

Xiao Chengping, who had never had any knowledge in this area, was fascinated, and of course, the most important thing was that he was finally able to extract the chakra!

Time back to this afternoon, ninja school, big classroom, ninjutsu class.

"To use ninjutsu, you have to draw chakra. And to extract chakra, we must first understand what chakra is. Chakra is the energy necessary for the use of ninjutsu, and this energy is synthesized through the 130 trillion cells in the body, absorbing the body's energy one by one, and the spiritual energy that has undergone many exercises. That's why the teacher needs to train you so hard this morning, without the morning's training, you won't even have spiritual energy, and it will be impossible to extract chakra. Alright, let's try it out! ”

"Ahh It's that simple! "I didn't expect it to be so easy! I'm going to give it a try! As soon as the teacher finished speaking, the students below were already boiling and talking.

"Chakra is a combination of physical energy and spiritual energy, and the spirit is the spiritual energy formed by many exercises, which can be understood as 'will'. But how do you get the body energy extracted from the 130 trillion cells in the body one by one? Why do they all say, 'It's so easy'? What the hell is this reaction!! Bandai Seihei kept his mouth slightly open, but his heart was roaring wildly!

Extraction, how to extract? How exactly do you extract it? What the hell! It's a thing that can't be figured out!

Thinking to no avail, Bandai Seihei, who was already close to going berserk, decided to ask questions to the classmates around him. He looked left and right, and finally decided to ask the classmate on the left, which was a classmate sitting next to him: "That, hello, my name is Bandai Chenghei, do you know how to extract energy from the cells of the body?" ”

Sitting to his left was a boy with a watermelon head and thick eyebrows. He has a scarf tied around his neck and a black bodysuit! At this time, there may be two thick eyebrows in the entire Konoha Village, but in the ninja school, there is only one person who is thick eyebrows, and that is - Maite Kai!

Although Kai is an idiot in terms of human sophistication, he is undoubtedly an enthusiastic guy, he will definitely be very enthusiastic to tell Wandai Chengping the answer, and he is a person who is proficient in physical arts, he must know more about the human body than ordinary students!

"Huh? Are you asking me? Okay, enthusiastic Kai will tell you the answer! Kai said with a thumbs up and his trademark front tooth smile!

"I've seen it in the comics, but it's really more impactful in reality! In particular, his eyebrows are really thick! "Bandai Seihei has become a big mouth and slightly open mode again, if he is in the comics, he may be in a petrified state!

After the signature action was done, Kai began to get down to business: "Your question is actually so strange, how to draw body energy from 130 trillion cells?" Isn't it just about drawing energy from 130 trillion cells? Kai looked at Mandai Seihei with a puzzled expression.

"Wait, what do you mean? I'm confused about what you said. I'm asking how to draw energy from the body's 130 trillion cells. Thinking that Kai hadn't heard his question clearly, Bandai recounted it again.

"Drawing energy from 130 trillion cells is drawing energy from 130 trillion cells." Kai replied with a look of course.

Bandai Chengping's muscles burst out, "What is this answer, is he really an idiot..." In the end, he thanked Kai for his help with a smile on his face, and no matter what, others answered his question.

He looked to his right again, and it was also a boy, with silver hair, staring intently at the book in his hand, and all the features under his eyes were obscured by a thick mask, making it impossible to know his true face. But even so, it has to make people think that he is a very handsome Zhengtai.

As if sensing Cheng Ping's gaze, he also turned his head to look at Cheng Ping. Then the two Shota looked at each other like this, and their eyes flashed with curiosity. How can a little kid have such a thing!

"Hello, my name is Bandai Seipei, excuse me..." Before Bandai Seihei finished speaking, the silver-haired Shota had already interrupted him: "My name is Kakashi Hagi, I heard your question just now, although that guy is very strange, he is not wrong." It's strange for you to ask this question. "This boy is none other than Kakashi Hachiki, who will later be known as the Copy Ninja, and now he is just a handsome little guy who doesn't like to take the initiative to talk to people.

In this way, he knew Kakashi Hachiki, but what was his answer? That guy is a genius, and he grew up in the former Great Clan Banner, and his answer must be fine. So what the hell am I mistaken?

Kakashi Hachiki saw that Bandai Seihei didn't reply, so he turned his head to look at the book in his hand again. Of course, he would have known this kind of thing a long time ago, so he looked at a book in the clan at this time.

"Thank you for your answer." Bandai Seunghei thanked Kakashi Hachiki and continued to think about it.

Kakashi turned his head a little strangely, and of course Bandai Johei had already turned his head and didn't notice. "This guy said thank you without waiting for me to respond."
