April 2837 in the Valoran calendar.

It has been more than a week since Chen Yin returned to the War Academy, and because of his status as a trainee, every day, he has to go to the Martial Arts Branch to help substitute for two classes, and then go to the Academic Affairs Office to make up for the content of the cultural classes that have been absent for two years, and also to participate in inexplicable teacher training courses.

With Chen Yin's return, the news has spread throughout the entire body of the War Academy, and many students from other branches have chosen the courses of the Fighting Branch in the elective course, even so, they still can't meet the most powerful senior in the minds of this low-level cadet every time. Finally, through the leakage of the intelligence of the students within the Fighting Branch, the students of the other branches mastered Chen Yin's teaching time, and many students from other branches even skipped class and ran to the Fighting Branch, just to meet the famous Valoran senior.

On the one hand, he had to prepare for class carefully, so he couldn't let these admiring juniors and sisters see the jokes, and on the other hand, he had to bear the anger of the teachers and even the deans of various branches.

Today, as in the past, Chen Yin came to the largest lecture hall of the Fighting Branch with a book in his hand, since his class was full, the door of the classroom was smashed and the glass was a frequent sound, in order to avoid continuous losses, the large ladder classroom of the Fighting Branch was used as an exclusive classroom for Chen Yin's teaching. It can accommodate at least 300 people.

Before entering the lecture hall, Chen Yin tidied up his bow tie and clothes again before reaching out and pushing open the door.

Today, there are still as many people as ever, the large lecture hall is full, and there are certainly not enough chairs, and the three stairs of the lecture hall are also used flexibly, and the students who do not have chairs take a piece of paper and spread it on the steps to become seats.

"Hehe, hello everyone!!"

"Hello senior!!"

All the students stood up and saluted respectfully, and they didn't ask the teacher like other teachers, Chen Yin's status as a trainee is equivalent to a substitute teacher, but in the eyes of these students, he is their eternal senior, and this title should not change until these students graduate.

"Please be seated!!"

Chen Yin waved his hand and motioned for everyone to sit down, then he picked up the book under his arm, picked up the chalk, and wrote a few big words on the blackboard, "Ninjutsu Analysis".

"Today, the content of the course is roughly the same as usual, according to the collection of martial arts books in our academy library, I will randomly select one and then analyze it according to my understanding. The book in my hand is "Gowa Jue" written by one of Ionia's former top ninja Musashi seniors, which explains many of the essentials and methods of ninjutsu. As usual, in order to avoid chaos in the classroom and affect the learning process of other students, in the process of my explanation, which student has a question, or a student who wants to ask a question, your question, please remember that the question asked must be related to the content of today's class, students, do you have any questions? ”

"No!!"

"Good! Then let's move on! ”

After getting the unanimous answer, Chen Yin smiled, picked up "Five Wheels", and began to explain.

In the first few teaching sessions, Chen Yin summed up a lot of experience, such as this one who asked questions according to the content of the lecture, at the beginning Chen Yin did not set any threshold, who just shouted "Senior, I have a question to ask." Or "Senior, I have a problem too!" Later, he found that this kind of teaching process was very unscientific, and there was a lesson in which he didn't even finish half of the book, and he had already heard the bell for the end of class, and at this time, he was answering a question from a junior about Chen Yin's experience in dealing with various magical beasts in the Iron Ridge Mountains. And this question has nothing to do with the book "The Essence of Stick Arts" he explained that day.

"Ninja, although the five elements of gold, wood, water, fire, and earth are used as the main means of lurking and hiding, however, the author, Mr. Musashi, believes that ninjutsu should not be based on escape and concealment, in his opinion, ninjutsu, is a real killing technique, and the five elements of escape or five elements of concealment, just to cooperate with the murder technique and borrowed techniques, if you want to learn ninjutsu well, you must first learn a variety of subtle killing techniques. At the same time, he also believes that all skills, in the face of absolute strength, there will be no room to play......"

"Senior, I have a question!"

Just as Chen Yin was talking about this, a student sitting in the second row raised his hand to ask a question, and under Chen Yin's smile and nod, the student stood up and asked his own question.

"The senior said that since the killing technique is the real ninjutsu, then suppose that one ninja has learned the Five Elements Escape and the Five Elements Hide, and the other ninja can only have exquisite killing skills but does not understand the Five Elements Ninjutsu, who will win the contest between them?"

"This, it depends on the environment in which the two of them live, whether it is a movable field or a fixed field. If it is a tournament in an outdoor convertible battle area, a ninja who knows the Five Elements will be undefeated, and if it is an indoor tournament with a fixed field, a ninja who does not know how to kill people and only knows the Five Elements will lose. ”

"I'll give you an example, as we all know, the Five Elements Technique is a way to borrow the power of the five elemental attributes generated by the power of runes, and then borrow the surrounding field scenes. When the battle scene is constantly changing, a tree trunk or a stone appears for no reason, which is not noticeable, and is also very suitable for escape or sneak attack. However, within a fixed scene, any sudden bulge or unnatural landscape will be immediately noticed, in this case, don't think about any tricks, and have the pure strength to crush the battle of life and death. ”

"I see! Thank you, Senior Chen Yin, for your explanation!! ”

The student sat down happily. At this time, another good-looking female student raised her hand to ask a question.

"Senior Chen Yin, can you show us the ninja killing technique you talked about? Let's take a look, what is the difference between pure homicide and traditional fighting with our fighting division? ”

This female student's question is a little difficult Chen Yin, it's okay to do a show, but you can't show the fresh lives of this group of juniors, right? Suddenly, a flash of inspiration flashed in his mind, and he reached out and touched the Ring of Time and Space, closing his eyes and staring for a moment.

"Yes, it's still here."

A life-size wooden puppet appeared next to Chen Yin, and if you look closely, there are still several obvious sword marks on the puppet's body.

"Hiss~~" "Wow~~Oh~~~"

There was a gasp and exclamation in the classroom, and no one knew how Chen Yin took out this puppet out of thin air.

The puppets in front of her were the last swordsmanship lessons that Fiona had before leaving, and the puppets when Fiona was doing the drill, Master Yi's alpha raid, made Fiona comprehend the Sky Breaking Slash and the Blade Waltz. After Fiona left the War Academy, Chen Yin went to the Sword Fighting Branch and asked for a few puppets and kept them in his Time and Space Ring.

Looking at this puppet, the short-haired girl who was looking for trouble everywhere in the academy came to mind, and the corners of Chen Yin's mouth curved a sexy arc.

"Look at it, Senior Chen Yin is smiling~~"

"yes, yes, it's so charming, it's so dazzling!!"

"Senior Chen Yin, don't move, don't move, I'm going to draw a sketch for you!!"

The noisy sound in the classroom made Chen Yin have an epiphany, and after realizing that he was out of shape, Chen Yin pressed his hand awkwardly and motioned for everyone to be quiet.

"I'm sorry, I was a little distracted. Now, I'm going to use this puppet to show you the difference between traditional fighting and ninja killing. Traditional martial arts are aimed at subduing the enemy, so they mostly focus on joint techniques, such as these joints, which are often attacked by traditional martial arts............ The ninja killing technique aims to attack the enemy's lethal organs and acupuncture points, and strives to kill with one blow, even in hand-to-hand combat, the attack point of ninjutsu will choose some areas with the densest plexus, such as here, here, and here...... The nervous plexus of the human body is mainly composed of these major parts, such as the cervical plexus, brachial plexus, lumbar plexus, sacral plexus, caudal plexus, etc......"

After Chen Yin set up the wooden puppet, he stood one step away, and with the explanation, he personally grasped and twisted with his hands, or stabbed with his knuckles, and hit his elbow joints, demonstrating the practical application of the two types of exercises to all the students present.

With the ringing of the bell for the end of class, Chen Yin's class officially ended, but more students still listened with relish and were unwilling to leave immediately, they shouted for Senior Chen Yin to speak for a while, but Chen Yin refused in a chic manner, and agreed with them with a smile that after 15 minutes, the next class would continue.

When Chen Yin walked out of the classroom and walked along the winding passage, he finally came to the door of the instructor's room of the martial arts branch, he saw a group of people standing outside, among them, a familiar figure of Mao Pengpeng made him feel very familiar.

"Brother Monkey! Why do you have time to come to our side today? Come on, come in and sit down and have a cup of tea! ”

Before Chen Yin could get to him, he began to greet Monkey King.

"Chen Yin'er, don't call me a brother and a brother to my grandson! What good things do you do that you don't know yourself? ”

"Me? What am I doing again? Brother Monkey, don't make trouble, I'm either studying hard or taking classes seriously these days. It doesn't seem like he's doing anything bad. ”

"Dare to pretend to be garlic with me!! Beware of my grandson smashing your faculty room!! ”

"Don't, don't, Great Sage, you have to let me think about it, what the hell is going on? Was it the last time we had dinner together, and I promised you the big banana in Bilgewater?? Akali should be back in a few days, and I've told her to buy it. ”

"Less nonsense, it has nothing to do with big bananas!! However, how many baskets are your daughter-in-law going to buy?? I'll tell you, oh, if there are two baskets missing, my grandson ......"

"Cough~cough~~Dean Sun~" At this time, standing beside Qi Dasheng, a teacher who arrived with him coughed lightly twice, reminding Monkey King not to forget the previous topic.

The reminder of the instructor next to him made the dean of the Gun Stick Branch, Monkey King, very embarrassed, he scratched his head and stared at Chen Yin viciously again.

"Okay, I'll be straight with you! The students of our academy, students of two classes, have skipped class and come to your side again!! What do you say, I warned you once last time!! If you don't give me an explanation this time, my grandson will definitely not be polite to you!! ”

"Oh, that's it, so I'm going to get rid of the girls and boys in the next class and let them go back to class. I have been reminded before each class that it is okay to come to my class if you want to, and I am always welcome during elective classes or free activities, and if you skip class, I will never welcome it. ”

"Just walk away? No, no, no, it's not over. You'll have to make amends to our Guns & Sticks!! ”

"Compensation?? Let me think about ......"

After Chen Yin scratched his chin, he looked at Sun Wukong and asked tentatively, "Bilgewater big banana?" Three baskets?? ”

After Sun Wukong heard the three baskets of big bananas, his eyes lit up, he licked his lower lip excitedly and just wanted to agree, but suddenly he had a flash of inspiration

"No, at least five baskets !!"

"Okay, deal!!"

A white palm and a furry palm were tightly clenched.

Like a boat of friendship, it stands like a rock in the river.

Watching the performance of the two, the other Gun Stick Branch instructor finally couldn't bear it anymore.

"Dean Sun, is it okay to talk about bananas later? We came here to ask about the lectures, the things about the lectures!! ”

Sun Wukong was reminded by the instructor in his own courtyard, patted his head, and remembered the real purpose of coming to make trouble this time.

"Chen Yin!! Not a banana thing!! It is because you have repeatedly seduced students from our branch to skip class, which has caused a very serious impact, and our branch has decided at a meeting that you must come to our gun and stick branch to teach two classes a day within this month, so that our previous holidays will be written off!! ”

"Class?? Oh, it's such a trivial matter, you just have to say it, Xingshi brought such a large group of people, I thought you weren't enough to give you bananas. Okay, okay, no problem, I'll start tomorrow afternoon, and I'll go to your side for two classes a day. ”

I didn't expect the problem that plagued the Gun Stick Branch to be solved so simply, except for Sun Wukong, the other teachers looked at each other, a little incredulous.

"By the way, Brother Monkey, since the bananas are enough, I won't send another book to Akali, it's still two baskets......"

"What???? Chen Yin'er, you deceive people too much!! Don't pull me, don't pull me, my grandson has to smash his faculty room today! ”

The bananas changed from five baskets to two baskets again, causing Monkey King to instantly explode into a state of rage, but at this time, the group of instructors he brought with him hugged him tightly. Refused to let him take half a step forward.

The boat of friendship is overturned......
