[Comprehensive] Heart tree

This seems to be a classical novel, Kakashi thought silently.

However, after reading a few pages, he thinks otherwise.

Who the hell wrote such a boring thing? Master Jiraiya and His Highness Hongying are so different in age, Master Jiraiya is even more than [-] years older than His Highness's mother, and "the king gave birth to me but I was not born". It can also be written together, the author's brain hole is also very strange.

Kakashi quickly scanned through this article, then turned back to the catalog, browsed the catalog column, he saw an article called "Wei Xiaocao", he turned over to read it, and after reading a page, he couldn't hold it anymore , he closed the booklet, put the book back where it was, and left there immediately.

After that, Kakashi understood the way the people in the hospital looked at him. He didn't feel anything when he didn't know it before, but now that he knew it, he felt uncomfortable.Even Sakura, who came to visit him, now looks at him with that look.

Sakura looked at Kakashi hesitantly for a long time before asking vaguely: "Mr. Kakashi, do you have, do you have any... have any thoughts about His Highness Hongying?"

"..." Kakashi rolled his dead fish eyes, he didn't want to answer this kind of question at all.

Seeing that Kakashi didn't speak, Sakura thought he was acquiescing, and Sakura was a little worried: "But, the age gap between Kakashi-sensei and His Highness is a bit big..."

"..." Why do these words sound so familiar.

"Besides, Mr. Kakashi is going to the hospital at every turn, His Highness's parents will definitely not agree."

"..."

"His Highness doesn't look like he likes Mr. Kakashi either."

"..."

"Ms. Kakashi is not young anymore. It's hard to find someone he likes. Who knew it would be so difficult. There are more than one or two people who like His Highness."

"...I said Sakura," Kakashi held his forehead, "You think too much, there is nothing at all, stop thinking about it."

"Eh?" Sakura blinked, "Isn't there?" Sakura, who just realized it, blushed immediately, "Yes, I'm sorry, Mr. Kakashi! I was thinking too much!" Sakura stammered Explaining, "It's all, it's all because of the book that the nurse sister insisted on giving me, I almost believed it."

"Don't read too many strange books, Sakura."

"Oh, okay," Sakura Nono, who hadn't recovered from her senses, responded, and when she realized it, she raised her voice, "Ms. Kakashi, who never leaves bad books anytime, anywhere, is not qualified to say such things."

"Well, don't worry about such details." Kakashi waved his hand.

"It's not the details!"

Ever since he read the novel called "Waiting Grass", every time he sees the red jacaranda, Kakashi can't help but think of the content there, and then he can't help but feel embarrassed, so he quickly went through the discharge procedures, Avoid red jacarandas.

After being discharged from the hospital, Kakashi, who hadn't been to a bookstore for a long time, went to the bookstore and bought all the latest intimate series that the boss had left for him.

After paying the money, the boss asked: "Kakashi, how about the book I gave you last time?"

"……Okay."

"There's one left here, it's the second volume of that one, do you want it?"

"...Thank you for your kindness, I am still suitable for reading this kind of book." Kakashi raised the intimacy series in his hand and forced a smile.

"Are you sure?" The boss raised the book, "This is the last one, and it will probably be out of stock in the future. Think it over."

"Let him go." Kakashi waved his hand.

Seeing that Kakashi lacked interest, the boss stopped mentioning it.

The plum-colored pamphlet was widely circulated in Konoha, and later Mrs. Yuzi also knew about it, and she asked Ayaka to get a copy.

After reading a few pages, she threw the book on the ground: "Ayaka!"

"exist."

"Go, buy all these bastard things and burn them clean for me."

"Yes." After taking the order, Xuanxiang immediately got up and prepared to leave.

"Wait a minute," Mrs. Jie Zi called to stop her, "Go and find out which publishing house this is, buy it, and you will not be allowed to publish anything in the future."

"Yes."

Ayaka collected hundreds of copies of this booklet, and she burned them all, but the publishing house couldn't find it, because this booklet was just a derivative novel of "Fang Xun Lu" that a group of readers raised funds to print, and it was never published society.

After learning the whole story, Mrs. Yuzi asked Xuanxiang to buy back as much as possible of "Fang Xun Lu" circulating on the market and destroy them, and asked her to buy the Long Bridge Publishing House that published "Fang Xun Lu" Come down and let them destroy the related negatives, so they can't reprint that kind of thing in the future.

Ayaka recovered most of the books, only a small part could not be found. Although Mrs. Yuzi was still angry, she had to give up.

Konoha's winter is over soon.

In the spring, the first big thing Tsunade encountered was that she received a lot of debt collection notes, many, many, from all over the world.Jing Yin felt overwhelmed by the debt dunning notes for the first time when she first saw these dunning notes.

Tsunade is very worried, it is not good to be Hokage, and she has no way to avoid debts now.When Hongying saw these debt collection notes, she was a little surprised, so she asked Tsunade why she owed so much debt.

Tsunade is also embarrassed to say why he is so obsessed with gambling as an African.Shizune at the side counted out what Tsunade did one by one with infinite resentment.

After listening to Jing Yin's words, Hongying still didn't understand why Tsunade lost so completely, she asked: "Master Tsunade, what kind of games do you usually play?"

"This," Tsunade got excited when he mentioned this, "I can play everything!" As he said, Tsunade introduced the games he had played to Hongying one by one.

"Master Tsunade! How can you tell His Highness this!" Seeing that Tsunade said this to Hongying, Shizune hurriedly stepped forward to stop him.

"Just talking, what does this matter." Tsunade waved his hand indifferently.

"It's okay, Miss Jingyin." Hongying also said.

The overwhelmed Jing Yin had to let them go.

Naruto would send some practice logs from time to time. Although his expressions were sometimes strange, Hong Ying still liked to read them.When she was in the hospital, she had nothing to do except for examinations and classes. Every time she came to this time, she would take out Naruto's practice diary to read.

Occasionally, she would also write something, and the nurse would not interrupt her when she saw her writing something when she came in.

After the turmoil in the pamphlet, Kakashi still came regularly to inspect and teach the red jacaranda. Although when he saw the red jacaranda, he would think of the words in the pamphlet from time to time, but he was an elite ninja who had gone through a lot of wind and waves, and even this little embarrassment If you can't overcome it, it's too bad.

Recently, there were a lot of papers piled up in Hongying's ward. Several times, Kakashi saw Hongying writing and drawing on them. He couldn't hold back his curiosity, and asked, "Your Highness, what are you writing?"

Seeing him asking, Hong Ying didn't speak, just handed him some papers.

Kakashi took it and flipped through it. After reading a few pages, he looked up: "This is?"

"A permutation calculation of the number of ninjutsu theories."

"!" Kakashi was surprised, "Your Highness is studying this these days?"

Hongying nodded: "Because I heard that there are many types of ninjutsu introduced by Junin, so I wanted to try to write them down, and then I found that I can use the method of arrangement to calculate the theoretical number of ninjutsu."

"...Then, has His Highness calculated any results?"

"This result probably cannot be calculated. There are 12 kinds of ninjutsu seals. Some ninjutsu can be activated without seals, some ninjutsu can be activated with only one seal, and some ninjutsu needs several seals. Ten seals can be activated, and some ninjutsu are compound ninjutsu composed of two or more simple ninjutsu. Now let’s not talk about non-seal ninjutsu and compound ninjutsu. Theoretical number of ninjutsu. Assuming that this type of ninjutsu cannot repeat the same seal, then the upper limit of this type of ninjutsu is 12 times. In theory, there are 12 types of ninjutsu that can be activated with one seal. There are 132 types of ninjutsu that can be activated with three seals, 1320 types with three seals, 11880 types with four seals, 95040 types with five seals, 665280 types with six seals, and 3991680 types with seven seals. There are 19958400 kinds of eight printings, 79833600 kinds of nine printings, 239500800 kinds of ten printings, 479001600 kinds of eleven printings, and 479001600 kinds of twelve printings. Adding up these numbers, the total is 1302061344 kind."

"..."

"This is just an ideal situation where the same seal cannot be repeated in the same ninjutsu. In fact, it can be repeated when the ninjutsu is activated. Even if a ninjutsu only needs to form three seals, these three seals can also have the same There is no upper limit to the number of seals that can be repeated in the same ninjutsu. Then the upper limit of the number of seals in a ninjutsu can be 1, 2, 3... 13, 14, 15... In this way, If it goes on wirelessly, the number of ninjutsu upper limit is itself a permutation problem, then the number of ninjutsu is a permutation problem. Therefore, the number of ninjutsu is theoretically infinite and cannot be calculated.”

"..."

"However, the actual number of simple knot ninjutsu is far less than this number. In theory, there should be an infinite number of simple knot ninjutsu that can be developed."

"..."

"In addition, there are non-knotting ninjutsu and knuckle compound ninjutsu that cannot be counted. Also, if the ninjutsu of mutual generation of attributes is activated at the same time, a new ninjutsu will be produced. I think this new ninjutsu, no matter what it is called It is not suitable for simple ninjutsu or compound ninjutsu."

Kakashi, who was overwhelmed by the huge amount of information, finally came back to his senses. He asked, "What new ninjutsu?"

Hongying didn't speak, but began to form seals, her left hand formed the water escape seal, and her right hand formed the wind escape seal, the two were born together, and Kakashi saw the ice escape he had seen before.

"...This..." Kakashi tried hard to suppress the horror in his heart, "Your Highness, please remember, don't use this in front of people again, absolutely not." It is enough to cause turmoil in a country. This method can allow ordinary ninjas to achieve the special abilities of ninjas with blood succession limits. If this matter gets out, the consequences will be disastrous.

"I know," Hong Ying put away those papers, "I will destroy these things, and I won't tell anyone about it."

"No, these are His Highness's painstaking efforts and cannot be destroyed," Kakashi stopped her, "Your Highness," Kakashi paused, "Although it is a bit strange to say such words suddenly, do you trust me?"

Hongying blinked, but without answering, she handed the thick stack of papers on the table to Kakashi.

Kakashi took the stack of paper that was not very heavy, and said solemnly: "Thank you for your trust, Your Highness. In the name of my Hatake Kakashi, these things will never be passed on."

"Thank you, Mr. Hatake."

The author has something to say:

As a liberal arts student who has abandoned mathematics for many years, I have tried my best. If I make a mistake, please remind me, I am really guilty.

从12种印中分别取1、2、3……10、11、12个印排列起来，可以组成多少种排列（每一种排列都可以发动一个忍术，排列的数量就是忍术的数量）

12+132+1320+11880+95040+665280+3991680+19958400+79833600+239500800+479001600+479001600=1302061344

The following is my nonsense ninjutsu classification, which is classified according to whether ninjutsu is sealed or not:

Ninjutsu is divided into two categories: non-knot ninjutsu and knuckle ninjutsu;

Among them, jieyin ninjutsu is divided into jieyin simple ninjutsu and jieyin compound ninjutsu;

Simple yin jutsu can be further divided into simple yin jutsu that cannot repeat the same seal and simple yin jutsu that can repeat the same seal.

The red ying is the part of "simple seal ninjutsu that cannot repeat the same seal".
