Ji Aojian slowly got up and asked, "Third sister, you just said that you wanted to teach me to combine two swords?"

"Well, that's right. Ji Shengdian sat back in his chair, "Tell me, in your understanding, what is the most important thing about the combination of two swords?"

"Is it a heart-to-heart connection?"

"No, think again. ”

"Oh, the premise of the combination of the two swords should be to have a vision, right?"

"Vision?"

"yes. Ji Aojian said excitedly, "As long as you find a strong companion, hug your thighs, and follow her, you will be invincible in the world immediately, such as my sister who is an invincible young genius and beautiful girl......"

"Why do you always want to hug your thighs?" Before he finished speaking, a pine nut smashed over, "With your mentality, with a strong teammate, you will also be killed by you!"

"I can't figure out what the key points are. Ji Aojian said with a sad face, "Third sister, if you want to exert the power of the two swords, why don't you have the same heart?"

"Because of the same heart, it's so inefficient. ”

"Inefficient?"

"The so-called combination of two swords is actually a cooperation between two people. Ji Shengdian said, "Maybe it's not easy for you to realize when the two people are swordsmanship, but if three people come to set up the Sancai Sword Formation, four people come to make the Four Elephants Sword Formation, and seven people combine the Seven Star Sword Formation, then you have to be able to communicate with each other first?"

Ji Aojian hesitated, "As long as we communicate together for a long time and slowly achieve heart-to-heart communication, it's not impossible, right?"

"Oh, then if you set up a formation of hundreds, thousands, and ten thousand people, so many people will have to have the same heart?"

“......”

"Based on your understanding, we can deduce this. Ji Shengdian dragged out his voice. "At that time, 300 Spartan warriors guarded the hot spring pass and blocked the Persian army of 100,000. It is because everyone has the same mind and has set up a wonderful formation. to create miracles. ”

"Really, those three hundred warriors are all in the same mind?"

"Yes, they eat, live, sleep and practice together in the barracks every day, exchanging feelings and sparks all the time, of course, they have the same heart. Ji Shengdian said solemnly, "Good friend, for a lifetime." ”

"Poof-" Ji Aojian almost didn't spit it out, "Third sister." That must be wrong!"

"Then tell me, why can three hundred warriors win more with less and outnumbered?"

"Because they have been trained in military discipline and have iron discipline. ”

"Well said. Ji Shengdian nodded, "Then let's take a look at the large-scale concerts performed in the opera house, which are often large orchestras of hundreds of people. With so many musicians acting at the same time, why is it possible to play a beautiful and harmonious symphony in unison, instead of playing its own strings? To each his own trumpet?"

"For all who play musical instruments are commanded in all their actions. ”

"Do we need to be connected?"

Ji Aojian shook his head, "No need. ”

"Then you talk about it now, what is the key to the combination of the two swords?"

"The essence of the combination of two swords. It's a collective action. "The most important thing for collective action is discipline. ”

"That's right. ”

Ji Shengdian raised two fingers. "What I'm going to tell you next. There are two main misconceptions about the phenomenon of combining two swords. ”

"What are the two misconceptions?"

"The first. It's called multiplication. ”

"What do you say?"

"In your opinion, what kind of power should be exerted by the combination of two swords?"

"I think the highest level of the combination of two swords, the power is doubled on the basis of the two combined, it's normal......" Ji Aojian said this, and suddenly felt as if something was wrong, "Third sister, what do you mean, this is an illusion?"

"Isn't it?" Ji Shengdian said with a smile, "Why are two people with two swords combined, and they can compete with four people for no reason?"

Ji Aojian muttered, "Isn't this an incredible thing, third sister, haven't you heard the relevant legends in the martial arts?"

"What legend?"

"Not only is it a combination of two swords, some magical martial arts formations can multiply the combat power all the time. Ji Ao Sword God said mysteriously, "Three people are twice as powerful as two people, four people are twice as powerful as three people, and five people are stronger than four people, and they can continue." ”

"Is there such a thing?" Ji Shengdian looked surprised, "Tell me clearly, which family's martial arts path is this?"

"It is said that this is the secret of the Wudang Sect. Ji Aojian whispered, "Up to seven disciples can set up a formation, and they can compete with sixty-four masters of the same level at the same time......"

"Stop, you didn't learn math well!"

"Oh. Ji Aojian hurriedly calculated, "The seventh power of two should be competing against one hundred and twenty-eight masters at the same time." ”

Suddenly, I heard a sound on the table, but I saw Ji Shengdian take out a black and white checkerboard and put it on the table, and couldn't help asking, "Third sister, do you want to play chess with me?"

"No, I'm here to prove your fallacy. ”

"This is a chess board, how can I prove that I am not right?"

"Little sword, haven't you heard of a well-known story in the world of mathematics?" Ji Shengdian said slowly, "In an ancient country, there was a wise minister who invented chess and presented it to the king. The king, who was so fond of his play, that he wanted to reward the minister again, asked him what he wanted. The minister said that if you put a grain of wheat in one square of the chessboard, each square will double the amount of wheat in the future......"

"Sixty-four squares will do!"

"Good, good, you've heard of it. Ji Shengdian said with a smile, "Come on, tell me, that kind of magical martial arts formation, each additional person can compete against twice as many people, if sixty-four people put up a formation, how many people can be beaten?"

"The whole world, no, no, the number of people in the entire galaxy is not enough!"

"Then you calculate, how many people are needed to compete with a master equivalent to the number of people on the entire earth?"

“...... Only thirty people are needed. ”

"Alright. Ji Shengdian lit the chessboard, "Do you still believe that such a magical martial arts formation exists?"

"The effect of this formation is really ridiculous. ”

Ji Aojian sighed. asked, "Third sister." How much combat power can the combination of the two swords actually increase?"

"It's good to be able to practice with a 30% increase. ”

"Okay. Ji Aojian felt that he almost understood. "What's the second misunderstanding?"

"The second misconception about the combination of the two swords is called a lossless victory. ”

"What does that mean?"

"An undestructive victory is a false expectation that arises on the basis of the first delusion. Ji Shengdian said, "The world thinks that the combination of two swords can double the combat power, and one plus one equals four." As a result, with such a powerful increase in combat power, it is almost invincible in the world in terms of psychological feeling. ”

"Well, it seems to be true. Ji Aojian thought and said. "To some extent, the combination of two swords seems to be really synonymous with invincibility in the world, at least it can also kill the enemy beyond the level. ”

"Since the combination of the two swords seems so powerful, it seems that it can easily kill the demon and save the world, so it has gradually become a poetic way to fall in love. ”

Ji Shengdian said with a smile, "In people's imagination, anyone who practices the combination of two swords must be a fairy couple." It must be hand in hand hand with the rivers and lakes, it must be that there has never been an opponent under the sword, it must be that the gods block and kill the gods and Buddhas, right?"

"This ......"

"When I first mentioned that I was going to teach you how to combine two swords, did you feel a little different?"

Ji Aojian blushed. "No, not really. ”

"The combination of two swords is just a way of fighting with two people. One man and one woman can practice. Two men can practice, and two women can also practice. Ji Shengdian continued. "And as for the outcome of the battle, it may be won. It could be a draw, it could be a loss, and of course it could be a death. ”

"That's good. ”

However, for those who see the combination of swords as a way to fall in love, they cannot afford to fail. Ji Shengdian said, "If one person unfortunately dies, then the other person has to accompany him." ”

"If they're willing to live and die together, there's nothing wrong with that, right?"

"As a way of fighting, the goal is to win, and the idea of living and dying together is not necessary, and sometimes it is even necessary to sacrifice the other party for the sake of victory. ”

"Sacrifice your companions?"

"yes. Ji Shengdian looked like a matter of course, "The combination of two swords is a collective action, since it is a collective action, there must be a leader, in order to unify the command, in order to avoid the conflict of ideas, in order to have the greatest execution, isn't it?"

"That's right. ”

"So when I join forces with you, who is in charge?"

"Third sister, your martial arts are stronger than mine, and your mind is smarter than me, of course you are the commander. ”

Ji Shengdian smiled and nodded, "For example, when we join forces to fight against a strong enemy, I think that there is no chance of winning according to the ordinary way of playing, so it is possible to take the initiative to let you block the sword and lead to the enemy's flaws." In the end, although you kill your opponent, you are also sacrificed. ”

"Oh. Ji Aojian thought for a moment, "In order to win, this is a necessary tactical option. ”

"Don't you feel wronged?"

"If no one sacrifices, both will die in vain. Ji Ao Kendao, "If I sacrifice in exchange for victory, not only will I avoid the death of both of us, but I will also avenge myself, this is the only choice that I don't have to think about at all." ”

"Have you ever wondered why you have to be the one who was sacrificed?"

"Because you are stronger than me, third sister, and the value of the battle is more important than me, you have a greater chance to seize the opportunity to win. ”

Ji Shengdian stared at him for a while, and said lightly, "That's it, in collective action, it must be commanded by the most capable person in order to maximize the combat power of the team." ”

"Hmm. ”

"So Xiaojian, when I feel that your ability is better than mine, you will be in charge. ”

Ji Aojian asked strangely, "Third sister, why did you suddenly say so far?"

"Far away?" Ji Shengdian smiled softly, "Little sword, you can sacrifice me when you need to, tell me you can do it." ”

“...... I can do it. ”

"That's right. Ji Shengdian clapped his hands and said, "Xiaojian, for the sake of winning the battle, if I sacrifice you, I will dig you and bury you afterwards and cry." However, I will not be martyred for you, I will go with you. ”

"Of course, third sister, you have no feelings for me...... No, no, no, I mean, you and I don't have a relationship. (To be continued......)
