After sending everyone away, Liu Bei remembered that according to Ge Liang's suggestion, he immediately organized a few cronies and sergeants to Ge Liang's house to receive training from Huang Yue, learn what Morse code was, and brought Pang Tong and Xu Shu and others to visit together. Pen "Fun" Pavilion www.biquge.info

Pang Tong saw this for the first time, and felt very novel, when he saw Huang Yue and Xu Shu respectively using gestures, lights, and drums to accurately convey a lot of information, I had to admire this Zhuge Liang couple to really think that they could come up with such a convenient thing, and immediately suggested to Liu Bei: "Jiangling City is surrounded by dozens of miles, we can build a tall building in the center of the city, and then place a stove and bronze mirror, gongs and drums, etc., when the Cao army comes to besiege the city in the future, The lord can sit in the city and always grasp the offensive and defensive situation of the four gates, and command the team in time to echo each other. ”

Liu Bei nodded and said, "This is what military advisor Kong Ming explained to me when he recommended this password to me. He said that on sunny days, you can use bronze mirrors to reflect light, rainy days can be used to beat drums, and at night you can use firelight and other methods to convey military information. Originally, I didn't expect to be separated from several people so soon, and I was not well prepared, so I only let Jian Yong and Guan Ping learn it. Now that they are all out, I hastened to find a few people to learn from them, just so that I can arrange liaison personnel on all sides of the city wall. Sir is right, we must hurry up and build a tall building in the middle of the city to accept the military intelligence of the eight directions. ”

Pang Tong said: "It turns out that Guan Ping and Jian Yong have already learned this, so if they return, even if they encounter the siege of Cao's army, as long as the weather is suitable, they can find a way to directly convey the military situation to us from the river." ”

Liu Bei said to Huang Yue: "Yuan Zhi still has to work with me to arrange the defense of the city, and the training of these ten sergeants will be troublesome to Madame." ”

Huang Yue was shocked by Pang Ruo, and saluted Liu Bei again and again: "I must not disappoint General Zuo." "Who said that the women of the Three Kingdoms have no status, didn't I be appointed as a military instructor by Liu Bei?

Pang Tong was reluctant to leave: "Lord, I want to learn from them here." ”

Liu Bei thought about it, such an important strategist as Pang Tong would definitely need him to be in charge of one side in the future, and it would be much more convenient for him to master this skill by himself, so he nodded and agreed.

Pang Tong has a smart head, and after only learning to write down the number code for a while, he immediately asked someone to bring a pen and paper, and took a copy of the code book back to memorize it himself.

Huang Yue hurriedly stepped forward and said, "Pang, Pang—" She didn't know what to call it.

Pang Tong understood: "Just call me Shiyuan." ”

Huang Yue breathed a sigh of relief and said, "Well, Mr. Shiyuan, I still have something I want you to see." ”

"Oh, what is it?" Pang Tong thought that this Mrs. Zhuge could figure out this code, and it would definitely be a new thing to take out again.

Huang Yue handed over a drawing: "Well, this is it." ”

Pang Tong took the drawing and looked at it, there was a rectangle painted crookedly on it, and a small hole was dug in the middle - this painting level is too bad, what kind of thing is it?

Huang Yue knew that he was not used to drawing ugly with a brush: "Please don't laugh, sir." ”

"And what are you drawing on this?" Pang Tong thought to himself, what kind of password is this?

Huang Yue didn't answer directly, but asked first: "In this battle, when the Cao army attacked the city, did it have to climb up the stairs on the city wall?" ”

Pang Tong nodded and said, "Yes, unless they can fly." ”

"Well, also, they'll be attacking the city and firing arrows to cover it, right?"

"Yes, otherwise we can lie on the head of the city and just take the bamboo pole and stab them down one by one."

"Well, then our soldiers must be guarding the city with shields and swords."

"That's right."

"You can't make something like this?" Huang Yue pointed to the drawings and explained to Pang Tong, "It's like this, making a big wooden board and putting it against the battlements should be better than one person holding a shield to defend against arrows." ”

A shield the size of a door, of course, is better to defend against arrows, but who has the strength to carry it around? However, Pang Tong still asked patiently: "In addition to making a shield, there should be other uses, right?" ”

"Well, I think so, won't the enemy climb the stairs and rush up the walls? I have heard that many brave and agile generals can risk their lives to rush to the city walls and cut down the defenders, but if we take this when he is about to climb up...... This door panel fell forward, and he was buckled underneath, and he probably couldn't get up. Huang Yue looked at Pang Tong with confidence.

Yes? And so it goes! Pang Tong was so surprised, if this gate board was covered, even if the enemy was tall, he would not be able to come up, he would have no place to grasp the grip and focus on it, just like a wall that protrudes outward at a right angle, how can he climb up?

Huang Yue saw that Pang Tong didn't answer, and continued to explain: "I think this thing should still be usable, because even if the enemy's martial arts are high and powerful, but he is standing on the ladder, it should be inconvenient to use force, and we can also send soldiers to lie on this plank to aggravate it." ”

Pang Tong first pressed the inner surprise, pointed to the square hole and asked, "Then what is this square hole for?" ”

"Well, this one is like this, didn't the enemy use a ladder when he climbed the city wall? The ladder must have been made a little higher than the city walls, otherwise they would have climbed up. If the ladder is higher than the city wall, then it is not easy for us to cover this door panel, so we dig such a hole, let the ladder pass through the middle and cover it again, and then the hole in the middle is not big, and people can't get through, we can throw stones from this hole to hit them. ”

Pang Tong usually studies strategic plans, and he doesn't think much about these small skills, but this thing seems to be really wonderful, so he said to Huang Yue at the moment: "You can think of it, but such a big thing, if the enemy's ladder is much higher than the city wall, wouldn't it be very difficult for us to cover it?" ”

It's also oh, but this is not difficult for Huang Yue, he took a pen and drew a vertical line in the middle of the door panel, and added a few horizontal lines to the vertical line, and said to Pang Tong: "Then that's it!" Make this an activity, just like two real doors, when the time comes, the stairs are stuck in the middle and then closed, and the deadbolt on the door will become a whole piece again! ”

Pang Tong didn't expect this woman to react so quickly, and said that Zhuge Liang had a smart wife, which was really worthy of his reputation, and asked Huang Yue: "Did you conceive this, or did your Kong Ming conceive it?" ”

"I came up with it randomly, and I'm afraid he'll laugh at me, so I'll ask my husband to help me take a look." Huang Yue's speaking level is also improving, so he takes credit for himself, and at the same time praises Ge Liang.

Well, Pang Tong was convinced: "I'll go to the lord to discuss, and hurry up to make a batch." ”
