If Ouyang Xiong promised Fan Yubin to train a cavalry that surpassed Manmeng before, then now he is ambitious.

Fan Yubin talked and wrote and painted, and finally handed over the focus of the record to Ouyang Xiong, and asked him to go back and participate in the research with his subordinates. Ouyang Xiong returned to the barracks overnight. When he left, his face was red and he was in good spirits.

Fan Yubin looked at Yan Wushuang in front of him, his eyes full of appreciation. Yan Wushuang is a Cheng Biting Jin-style character, he has a rough appearance, but in fact, he is thoughtful, and there is a trace of cunning and wisdom hidden under the arrogant and hideous appearance. Yan Wushuang has been fighting on the grassland for a long time, he has rich combat experience, is brave, invincible, loyal, and of course, a little clever.

When he competed with Fan Yubin on the training ground, he just wanted to attract his attention through a thunderous blow, in order to leave a deep impression. For Yan Wushuang's little trick, Fan Yubin has already seen through it and knows it. But Fan Yubin likes such generals. The art of war is not a cloud: soldiers are impermanent, water is impermanent, and soldiers are not tired of deceit!

Fan Yubin talked about equipment, training, and tactics, and especially explained in detail many little-known reconnaissance techniques and tactics in later generations. The more Yan Wushuang listened, the more excited he became, the more he listened, the more shocked he became, and the more he listened, the more he admired. Fan Yubin also recorded the key points of his story one by one and handed them to Yan Wushuang.

Then Fan Yubin opened the drawer of the desk and took out a few things from it.

What Fan Yubin took out of his desk drawer was a claircase, a small piece of camouflage net, a quiver made of cowhide, and a bottle of clear liquid.

Fan Yubin's face was solemn, and he solemnly said to Yan Wushuang: "Wushuang, the ancients: the wind starts at the end of Weiping. If you want to train an elite soldier, you must start with the details. It is the so-called accumulation of thick and thin. These are the things that I have been trying to give to you at night. When you go back, you have to use your brains too. Remember, military training is not only physical training, but also brain training. ”

Seeing Yan Wushuang's concentration and calmness, he listened quietly. Fan Yubin smiled slightly and said softly: "Not closing the night is the eyes and ears of the army. Since you are your eyes and ears, you must try your best to become clairvoyants and ears to the wind. ”

Fan Yubin picked up the clairvoyant mirror and the quiver made of cowhide, and then said: "This is the clairvoyant mirror, when observing the enemy's situation, it can make you become clairvoyant at night." This quiver made of cowhide is called a arrow. It can usually hold arrows. When you need to eavesdrop, you only need to take out the arrows, blow enough air, pill under your head, and listen to the sound, and the sounds of people and horses around you for miles are clearly distinguishable. ”

A kimono is a vessel for holding arrows, made of cowhide. In ancient times, it has long existed. It was invented by using the principle that the cavity receives sound.

When Yan Wushuang heard this, he couldn't help but be overjoyed. He knew that this thing was sold from the West, and the price was higher than gold, although Yan Wushuang dreamed of it, he didn't dare to hope for it. The Yafu looks simple and easy to use, and it is also a sharp detection weapon. Now I heard Fan Yubin say that the equipment for the night led by him is not collected, how can he not like it. However, the remaining two things, Yan Wushuang couldn't understand when he looked at them.

Fan Yubin looked at Yan Wushuang's stunned and stupid appearance, and couldn't help but laugh in his heart, he picked up the small piece of camouflage net, and said with a smile: "Good news for you, we can make and produce the clairvoyant mirror right away." Yafu, you can have as many as you want. As for this," Fan Yubin shook the small piece of mesh in his hand before continuing: "It's called a camouflage net." It's just a small piece, think about it, if it's a big piece, tie it with grass of the same color as the prairie, and drape it over people and horses as a camouflage。。。。。。 ”

"Sir, I see. These are the treasures that we don't collect at night! Before Fan Yubin finished speaking, Yan Wushuang screamed excitedly as if he had been beaten with chicken blood. As soon as he took the clairvoyant mirror, the costume arrow, and the camouflage net into his arms, he was afraid that he would be robbed later.

"You, you don't know the treasure in Baoshan!" Fan Yubin ordered the only transparent liquid that Yan Wushuang had abandoned on the table, and said with a smile: "This is a secret writing potion." ”

"Ciphertext potion?" Yan Wushuang's face was full of doubts, and he asked with a stammering mouth.

"Yes. It's a cipherwriting potion. Fan Yubin said as he picked up a brush, opened the bottle, and dipped the liquid in it with the brush to write a line of words on a piece of paper.

Yan Wushuang picked up the piece of paper and looked left and right, the paper was empty, and there was not a word.

Fan Yubin smiled, he stood up, took the piece of paper from Yan Wu's hands, unfolded it, and put it into a basin of water beside him.

Strange things happen. On the white and flawless white paper, a line of clear handwriting slowly appeared: the edge of the sword was sharpened, and the fragrance of plum blossoms came from the bitter cold.

Fan Yubin patted Yan Wushuang on the shoulder and said warmly, "This is for you to pass on information." That's not enough, though. In order to prevent self-defeating or other accidents, you also need to master the password. ”

"Password?" Yan Wushuang blinked with a pair of strange eyes, looking ignorant. Fan Yubin smiled, he took a book, and while flipping through the book, he wrote a few sets of numbers on the paper casually. After writing, he handed the paper to Yan Wushuang along with the book.

Yan Wushuang is a warrior carefully cultivated by the Fan family, and has practiced martial arts since he was a child. Literacy is just a piece of cake for him.

Fan Yubin told Yan Wushuang that the first number represents the number of pages in the book, the second number represents the number of lines, and the third number represents the number of words. Yan Wushuang suddenly realized, he quickly opened the book against the numbers, and wrote down the translated content on paper. Soon a line appeared on the paper: the night does not collect might.

"Sir, you are really a fairy. You can come up with such a brilliant idea. Yan Wushuang said in surprise and joy, his face was full of smirks, but this sneer appeared on his scarred face, which looked particularly weird and hideous.

Fan Yubin tapped the table with his fingers, his eyes were full of mockery, and he laughed and said, "You are good at slapping sycophants." But you have to be careful, beware of slapping the horse's hooves. ”

Yan Wushuang opened a pair of innocent eyes, he didn't care, his face was so thick that he could really do it.

Fan Yubin flipped through the book again, wrote down a set of numbers again and handed it to Yan Wushuang. Yan Wushuang was full of confidence, and quickly translated it according to the book, the words were translated, but the content was not in the right mouth, and he didn't know why at all.

Fan Yubin smiled and asked him to add one to all the numbers and then translate. The content was quickly translated, and it turned out to be: cheeky.
