In fact, it was indeed Kou Yan who ignored the problem. It is necessary to sacrifice heaven and earth, to know the three armies, to give a sword to the expedition, and to wear a golden helmet. Kou Yan consulted many classics and materials, and only then did he know that the matter was really taken for granted.

Now she was glad that Pang Tong didn't care about this, or even if he was careful, he wouldn't show it on the surface, after all, she didn't mean not to give him these courtesies, but she really didn't think of doing it.

Moreover, it is wartime, and there are many things that are not in such a condition even if you want to do them. Guy, Kou Yan just took this matter to heart.

On the other hand, Cao Ren also had a headache, although Cao Cao had retreated to the north, but after all, it was a big casualty of three or four hundred thousand, and he briefly went back to explain to the scholars who supported him in the north, so even if he knew that Xiangyang had been besieged and it was destined to be attacked, he was no longer able to support Cao Ren.

At present, Cao Ren has a total of 50,000 soldiers in his hands, including 3,000 cavalry, which are still the ones left after Xinye pursued Liu Bei. At the beginning, the battle loss ratio can reach 1:3 or even 1:4. However, in the next few troop dispatches, the battle loss ratio has changed, and it can only be achieved at about 1:2. This made Cao Ren unable to help but choose the timing of his troops more carefully. After all, the cavalry in his hands is very limited, and if the battle loss ratio is too high, he will suffer too much loss. After all, the soldiers in Changsha had not been worn out much before coming to Xiangyang. After entering and occupying Gangneung, he was supplemented by many soldiers, and these soldiers could not attack the city, so it was still okay to stand as cannon fodder.

Therefore, Kou Yan dug fortifications outside, built earth platforms, and was busy for almost a month, and Cao Ren was stunned in the later period to raise fat in the city. Kou Yan was contemptuous in his heart because of this, thinking that he Cao Ren would only fight with the wind, and he was also timid when he encountered adversity, and he didn't come out at first. Send cavalry to attack. Now that the cavalry is no longer being sent, they are staring at the city.

In fact, Kou Yan also knew in his heart that it was impossible for Cao Ren to fight lightly. He's the manager after all. Take full responsibility for the defense of the city. If he comes out, it would be bad if he was ambushed, even if there was no ambush. It can also be miserable to be entangled.

The reason why Xu Shu and Pang Tong agreed to Kou Yan's construction and built a lot of construction under the city was also to lure Cao Ren out of the city, but unfortunately Cao Ren changed his impulsive and belligerent temperament in the past, and became cautious and judged the situation. In fact, it is also because he is the only one in charge of the overall situation in the city, originally Cao Cao thought very well, Xu Huang guarded Jiangling, and after a certain period of time, he abandoned the city and went to Xiangyang to help Cao Ren, so that Cao Ren's mobility was stronger.

Now that Xu Huang is dead, Cao Ren has no helpers, so he is naturally more cautious. And Cao Ren learned that Liu Bei was defeated, and only Guan Yu and Liu Bei died, so he wondered if there was still Zhang Fei outside. How dare these three people act rashly when they are pestle him outside?

After working overtime for a month, the various fortifications outside Xiangyang City have been decent, and now they are waiting for catapults to be transported in large quantities. In addition, Jiangxia's good news has also come, with the help of Kou Feng and the cooperation of the people of Jiangxia, Gan Ningshun controlled the entire territory of Jiangxia, and chose his Taishou Mansion in Xiakou. All the remaining soldiers and horses brought by Kou Feng were left in Jiangxia, and Gan Ning's lieutenant general was temporarily under the control, and he took his own soldiers to rush back day and night, hoping to catch up with the battle of Xiangyang.

Kou Yan received the letter and said to Xu Shu and Pang Tong with a wry smile: "I, the senior brother, are too anxious, and there is no shadow of the attack on Xiangyang! My brother thinks too highly of me. ”

"Feng'er is a little anxious, isn't that because I'm worried about you? "Xu Shu has been relatively idle for a month, chatting with Pang Tong every day about major events, chatting about the art of war, and pulling Pang Tong to do wargame deductions when he has nothing to do. Xu Shu is the defender, Pang Tong is the attacker, the two of them are very happy to kill each other, Kou Yan is a good student on the side, and he observes carefully.

Through several wargame deductions, Kou Yan also saw some deep things in Pang Tong's character. He is not as cautious or even cautious as he appears to be. When leading troops into battle, he was also a strong, sharp man, and even occasionally went off the rails, exchanging great sacrifices for the hope of victory. This made Kou Yan even more glad that he had exchanged him for food.

After all, the teacher's style is just like his personality, and he has long lost the sharp momentum he had when he was a ranger, and has become stable. This kind of personality is supplemented by general strategy, which is the best candidate for defense, but with less sharp energy, the iron-blooded sense of attack is relatively less. And Pang Tong's joining just makes up for this shortcoming, with him, you can give Kou Yan more positive construction to reference, no longer have to stick to Xu Shu as soon as he encounters problems like before.

After covering the sky and inspecting the field fortifications, Kou Yan returned to the Chinese military tent and sat in the tiger case. Xu Shu and Pang Tong sat opposite each other, and Kou Yan seemed to breathe a sigh of relief and said: "These fortifications outside are finally decent, and I don't know how prepared the catapult is on Senior Brother Jiang's side, and when will it be able to be transported?"

"Gongyan is already stepping up manufacturing, and I think the first batch will be loaded into the ship in the next few days. Xu Shu reported.

"Well, I've been waiting for so many days, and it's not bad for a day or two. Is there any movement in Xiangyang City?" Kou Yan then asked.

"Xiangyang City has always been on high alert, but there is news that Cao Thief will send a general to Xiangyang by Lin Ai. It's just that the news is not very clear, whether the person who came to defend the city in place of Cao Ren or assist Cao Ren in defending the city. Xu Shu hesitated.

"Send someone else?" Kou Yan frowned when he heard this: "Cao Thief has always cherished Cao Ren very much, but he has only been returning to the north for a short time, except for recuperation, there should not be any big moves that need to use Cao Ren, plus Xiangyang is so important, I think this new general is here to help defend the city." In this way, our plan to attack the city must be carried out more quickly. Teacher, it's up to you to write an official document to ask about the situation. I also don't want to put too much pressure on Senior Brother Jiang. ”

"The subordinates understand. Xu Shu nodded.

Kou Yan turned his face and asked Pang Tong: "Senior brother has been here for a few days, and he must have already learned something about military affairs?" I don't know what senior brother thinks, with these resources we currently have, if Cao Ren comes to attack in person with his dragoon army at this time, can we be sure that we can stop him?"

"Don't worry, my lord, the soldiers have been working hard and diligently for days, especially the other departments of Captain Cen, and they are even more attentive, if Cao Ren comes to attack in person, I believe the soldiers will not let you down. Pang Tong looked confident at this time.

In the past few days, he has been researching at the grassroots level, communicating with Huang Zhong, Wei Yan, etc., and also saw the scene of the soldiers training in full swing, and has a new and more comprehensive understanding of Changsha's military strength.

"Hehe, hearing my senior brother say this, I suddenly felt a light on my face!" Kou Yan heard Pang Tong praise her army, and felt honored.

On this issue, Pang Tong was particularly sincere: "It is said that there are many warriors in Jing Chu, and you can see the whole leopard at a glance. In addition, the general and ordinary soldiers train together, and the amount of training is only a lot more, which also shocks me, especially General Huang, who has a white beard and hair, and is so strong and brave, which really makes my generation admire. ”

"General Huang is a treasure in our army, and it has really suffocated him to be idle in the army these days. Ask my teacher, he basically comes every day to ask when the city will be officially attacked!" Kou Yan heard Pang Tong praise Huang Zhong, and nodded thoughtfully: "It's not me who offers treasures, sometimes I also feel troubled by his belligerent character, on the one hand, I don't want to refute his face and make him unhappy, but on the other hand, I am always worried about the safety of his old man." ”

"Hahaha, little girl, I said in front of others that the old man was not, but the old man felt angry, you are the first!" Huang Zhong's trademark hearty laughter suddenly came from outside.

Kou Yan pretended to be helpless and spread his hands: "I just talked about you, why are you here!"

"If the old man doesn't come, how do you know that Lord Taishou is saying bad things about the old man behind your back?" Huang Zhong pretended to be dissatisfied.

"Where can I be! Senior Brother Pang and I, as well as my teacher, are praising you for your bravery and good fighting! There is not a single young man in the army who does not admire you. Kou Yan beckoned Huang Zhong to sit down and poured water for him personally.

Speaking of which, the old man would like to thank you for your genius last time, and the old man just took this opportunity to select the experts who are good at shooting in my unit and form a special team to carry out long-range shooting missions. In the past, there were many people in the old man's army who admired the old man, and there were many people who secretly practiced archery. Xiao Taishou's words to teach Captain Cen a lesson also reminded the old man that he should not cherish himself. Huang Zhong said open-mindedly.

"Your archery skills are amazing, how can you be a broom to cherish yourself! You can only blame that there are too few qualified soldiers in the army who can be favored by you. Kou Yan smiled and said: "However, your mention is very useful for our future siege warfare, the earthen platform built outside the camp, after the catapult is installed, the height of the city wall will no longer pose a threat to me, and then those marksmen in your army will be able to deal a fatal blow to the Cao soldiers at the head of the city!"
