Xu Yuanlang's face changed, and he said: "Lord Liu, what you say is against the military system of the Great Jin Dynasty, soldiers are soldiers, and the people are the people, so as not to cause chaos." ”

Liu Yu shook his head: "Lord Xu, what you said is usual, but now it is different, the enemy is current, the women, children, old and weak in the city have all been evacuated, and now there are only a few thousand men in Shouchun City, even if all of them are soldiers, it is not enough, and it is no longer appropriate to stick to the distinction between the military and the people." ”

Xu Yuanlang gritted his teeth: "Even if we are short of manpower, but the people have never been accustomed to warfare, and they don't know how to use weapons, how can they undertake the task of fighting?" Besides, they don't know how to listen to drums and gongs, and they don't know how to advance or retreat, so how can they fight? ”

Liu Yu smiled slightly: "These commands, aren't the sergeants never coming?" I guess I learned it slowly. Now the situation is urgent, and there is no time to train more, but as long as you tell everyone, you will go to the city to help defend when you hear the drums, and you will retreat down to the city when you sound the gong. ”

Xu Yuanlang's eyebrows raised: "Then dare to ask Lord Liu, since you are well versed in the art of war, what methods are you going to use to let these people who are not accustomed to war know how to behave?" ”

Liu Yu nodded, turned to the sergeants and people around him and said: "The way to defend the city is to judge the situation and make the best response. When the enemy army issued a large number of stones and arrows, the head of the city troops went down to the city first, leaving only a small number of elite troops to observe, the head of the city guarded there, with the cronies holding up the sign as the sign, the first time to raise the card, is in the place where the enemy is going to attack the city, fifty or sixty steps away from the city, in order to inform the reserve under the city to prepare. When the enemy's car crashes and rushes to the city, the sign is raised twice, and when the enemy's ladder is on the city, the card is raised three times, and the enemy army begins to climb the city, and when it is about to reach the female wall, it raises the card four times. ”

"After raising the card four times, it will be changed to raising the flag as the number, if the rolling stone and wood of the city are used up and need to be added, then the blue flag will be raised, if the gray charcoal brazier is needed, the red flag will be raised, if the city head is damaged and the sand and gravel and mud tiles need to be repaired, the white flag will be raised, and if the hot soup and dung are needed to drench the enemy, the black flag will be raised."

"If you need a warrior to sharpen your pawn, raise the dragon and tiger flag, and if you need a halberd sword, raise the eagle flag. If the enemy army ascends the city in large numbers, you can see all the fierce battles on the first line of the city wall from the city, and you can't raise the flag to call for help, then you will go to the city with your own troops, and the defenders in the city will also be dispatched at this time to reinforce the city. ”

Liu Yu's voice was not too high, but everyone could hear it clearly, at first many people were still talking in private, but as Liu Yu's explanation continued, even Xu Yuanlang looked at Liu Yu intently, pricked up his ears, held his breath, above the city, except for the sound of the wind, only Liu Yu's voice was floating back and forth.

"There can't be too many people at the head of the city at the beginning, the enemy must be a rain of flying stones and arrows, we will suffer a lot of casualties if we go up too much, the main force is placed behind the city wall to avoid their long-range weapon strikes, and it is really impossible to withstand the support of the city again."

"In addition, some city walls to be chiseled into secret doors, when the enemy siege is urgent, our army soldiers directly from these secret doors, rush into the enemy's siege queue and let go of the killing, in order to reduce the pressure on the city, these people kill out, the city gate should be blocked at any time, do not let the enemy follow in, if you can repel the enemy, then the city head rope will hang these dead soldiers out of the city."

Speaking of this, Liu Yu breathed a sigh of relief, looked at Yan Zhi, and said: "Here the military and civilians need to perform their duties, if the defenders of the city are insufficient, the people need to pick up their swords and fight with the enemy, but if according to my arrangements, the brothers still have to stay in the city, especially those secret gates that rush out of the city, you need to dig holes and plug them in the city wall." ”

Zhi Yanzhi nodded vigorously: "We are good at this, and among the twenty or so brothers who came with me, four or five of them are plasterers and carpenters. ”

Liu Yu smiled and said to these people: "How many of you are from plasterers? Please raise your hand. ”

At once, more than a hundred arms were raised, and many people shouted: "I can be a plasterer, I can work in plaster!" ”

Liu Yu nodded with satisfaction and said to Xu Yuanlang: "Lord Xu, please gather these people who can do muddy work, and do something important first." ”

Xu Yuanlang nodded in admiration: "Lord Liu, today's words can be regarded as convincing to me, I didn't expect that in addition to your martial arts, this command is also so good, no wonder Xie Zhenjun values you so much." Say, what do you want us to do? ”

Liu Yu Zhengse said: "Please also send capable and capable soldiers, so that these brothers who do muddy work will immediately plaster the houses in the city, the wooden buildings at the head of the city, the top of the trees, and the outside of the city gates, preferably wet mud, quickly, and must be completed before dark!" ”

Xu Yuanlang was surprised: "Why is this? ”

Liu Yu hooked the corners of his mouth, pointed to a wooden shield more than 20 steps away from Xu Yuanlang, and said, "Please shoot it with a rocket!" ”

Xu Yuanlang nodded, personally took a bow from a sergeant next to him, wound the arrow, two people in the arrow coated with fire oil, lit with flint, and suddenly the arrow rose flames, Xu Yuanlang's fingers loosened, the burning arrow went away from the string, and directly nailed the wooden shield more than 20 steps away, and soon, the whole wooden shield rose into flames, and more than ten sergeants and people on one side sprinkled water and fluttered with thick cloth, and finally extinguished the fire.

Liu Yu nodded, and said in a deep voice: "Everyone has seen it, a rocket hitting this wood will cause a fire, if the enemy army is attacking the city, if it takes advantage of the north wind and a large number of rockets to attack the city when the weather is dry, then the wooden buildings on the city wall, the canopy trees, and the houses behind the city wall will fall into a sea of fire." Therefore, to prevent this rocket siege, you have to rely on wet mud to extinguish the fire, once these wood is wrapped in wet mud, even if he fires ten thousand arrows, it is impossible to ignite! ”

Speaking of this, Liu Yu pointed to another wooden shield, this shield had already been smeared with a layer of soil about two inches thick according to his instructions, Xu Yuanlang once again a rocket wound, in response, when the rocket hit this mud shield, the fire on the head fluttered twice and then extinguished, and Xu Yuanlang immediately fired two arrows in a row, which was also extinguished by the arrow, and the crowd suddenly broke out with a burst of cheers. Xu Yuanlang laughed and threw away the bow and arrow in his hand: "Brothers who can work in mud and water, come with me quickly, before dark, the wood of Quan Shouchun must be wrapped in thin mud!" ”
