Zhuge Liang defeated Hou Cheng and Wei Xu on May 11th, and he thoroughly discovered the enemy's situation the next morning.

In addition, Zhuge Liang rarely stayed up all night, and based on the current situation, he estimated the countermeasures and plans for different enemy situations, and finally thought about several plans to "How to take over Guan Yu's orderly retreat when all the territory east of Anyi is lost."

Zhuge Liang could not make up for which specific set to be implemented at that time, because he didn't know how difficult the situation was on Guan Yu's side, and it was impossible to make a fuss. Therefore, Zhuge Liang roughly classified and briefly described the plans for dealing with various situations he wanted, and asked someone to bring information to Guan Yu.

It is equivalent to turning the legendary "trick plan" into a feasible "combat plan for the staff" in the real world. If there is a "top, middle and bottom strategy", you can choose this. It is not divided according to Guan Yu's personal preferences, but according to the specific enemy-to-me situation at that time.

There is no doubt that Zhuge Liang upgraded his tricks to the modern German General Staff model, which was exactly what he learned during his study with Li Su. After all, Li Su used his advanced concepts to do more than once, "Assuming that there are various situations in the enemy situation, I will do PLAN/A/B/C separately." After Zhuge Liang observed it closely, he also absorbed the methods of doing things.

The specific details of Zhuge Liang’s retreat plans are not stated for the time being. Anyway, there are several sets that are ultimately wasteful, so it is also a word of water.

It was said that at noon on the 12th, he sent a small group of secret envoys from Anyi, all of whom were elite warriors selected from Dian Wei, and asked them to take charge of the letter.

In order to keep it confidential, Zhuge Liang only wrote down the current situation in Anyi in words. As for the retreat plan he had thought for Guan Yu, it was not written in words at all. He just asked them to memorize it orally, so that even if the messenger was caught on the way, he would not leak the secret.

The people chosen were at least one to ten martial arts, and were equipped with good horses and relatively flexible and exquisite iron armor, horse-killing swords, and bows and crossbows. In addition, each brought several sheepskin bags that were full of breath but not heavy.

These skins can be tied together with a small number of wooden sticks when crossing the Yellow River to form a sheepskin raft.

The route Zhuge Liang arranged for them to report was to first cross some relatively flat Zhongtiao Mountain Pass from near Anyi and arrive near Dayang County, Hedong County, on the north bank of the Yellow River.

Dayang County is still under the control of Liu Bei's camp, and Zhang Liao has not yet divided his troops to fight such a remote place. The place is located on the north bank of Sanmenxia. There is a road to communicate with the county's Anyi, but it is rugged and cannot drive, so it can only walk. It is not possible to ride a horse on some sections of the road, so you have to get off the horse and lead it.

After arriving at the county town, these messengers had to walk a steep land route downstream for twenty or thirty miles. Some of the sections were on the cliffs on the north bank of Sanmenxia. After passing through the entire canyon area and the "mainstay" Dizhu Mountain, the terrain on both sides of the Yellow River would turn from cliffs to tidal flats. At this time, these messengers could log wood and raft, put down the sheepskin rafts and drift down.

When the head of the secret envoy team got the sheepskin bag, he asked curiously for advice: "Why do you have to travel dozens of miles of mountains and carry these inflatable sheepskins? Although it is not heavy, it is full and it is inconvenient to climb mountains, so it is probably easy to miss things. If you want to drift on the Yellow River, it will be too late to cut down trees and build rafts, and it will be very fast."

Obviously he was not questioning, but was just afraid of being burdened with the burden.

Zhuge Liang patiently explained: "I have arranged two elite soldiers in your team who fought with General Guan in the northwest. How to use this raft? Then I will listen to them. Do you have any special skills?

You locals in Hedong are not familiar with this thing, but when General Guan and General Ma were fighting northwest, they saw the Di barbarian kings crossing the Yellow River in Lanzhou with sheepskin rafts, and when they were in Yinchuan County, they also saw Qiang in Hexi, and General Ma himself used it.

These evil things have greater buoyancy than bamboo and wood. The key is that after I studied and improved it, I found that the sheepskin airbags are easy to fit into the human body. Even if the boat and raft collapse, they may indulge in holding the wood. However, the sheepskin airbags can be worn on the body, and as long as they are not broken or leaked, they will not be drowned. Even if they are wearing iron armor, as long as they calculate the weight of the inflatable buoyancy, they can be offset.

Zhang Liao had already reached Wenxi. I believe that other generals of Lu Bu had also occupied the north bank of the Yellow River east of Jiguan, and even occupied the Xiaopingjin Ferry on the south bank. Because of this, it is very difficult for you to report the message to General Guan. It is very likely to be exposed with a large ship. Only when a raft and a sheepskin raft can you break it into pieces and avoid it.

If the enemy's river patrol was tightly blocked in the end, you abandoned the raft, untied the sheepskin bag, put it on your body and swam in the night for the last dozen miles. If it really doesn't work, climb up the south bank and cross the mountains and pass through the mountains north of Hangu Pass.

I believe that General Guan’s current location is either in Xiaopingjin; or south of Xiaopingjin, backed by the edge of the mountains on the north side of Hangu Pass. The mountains north of Hangu Pass actually have river beaches or dangerous roads in the mountains to walk, but they cannot pass through cars and horses, so they cannot transport grain and cannot be used for large army wars.

If you have to climb a mountain, you should abandon the horses, but keep a few sheepskin bags, which will help you prove your identity at that time, so that General Guan will believe that the verbal suggestions you brought you who have not fought in Liangzhou will not think of using this, and this is also a token."

Zhuge Liang thought very thoughtfully, from how to rush to get the letter from the enemy, to how to keep the tokens to win the trust of Guan Yu, he thought of all three goals at one fell swoop.

Moreover, because he followed Li Su in this life, he was very talented in science and engineering. As long as the products of folk survival experience and wisdom fall into his eyes, he can always improve it with the physics knowledge he learned from Li Su, and it will be more systematic and efficient.

Look, the ordinary sheepskin raft that he learned about after Li Suxi's graduation trip was changed to "the sheepskin raft airbag and can be detached and worn alone in life jackets."

Well, it may be a bit of a gift on Zhuge Liang's face. This thing is actually not 100% from his wisdom. How could such a busy person think of such details? So, in fact, Zhuge Liang proposed the physical model, summarized the principles from a high-level perspective, and then asked his fiancée Huang Yueying to design it in practice, and then mass-produced it to the craftsmen in the military.

However, the theoretical model was created by Zhuge Liang's imagination, which is enough. As for tailoring, such as clothes, it is done by women. How can men do tailoring fashion design? Who designs if Huang Yueying doesn't design life jackets?

Because it is very expensive, a set of things here requires many sheep's skins, so it cannot be equipped on a large scale. It is just for secret messengers of special warfare infiltration to lurk in the river.

After the design, Zhuge Liang finally discovered another use of this sheepskin life jacket in the experiment before equipment. If the airbag is carried on the back, it is easy to be shot and exploded by crossbow arrows, but it can also block one or two powerful crossbows.

This thing is a bit similar to the one-time reaction armor in later generations. At least the effect is much better than the hollow cloth bag "mother clothes" carried by the elite cavalry "mother clothes" on their backs during the Warring States Period in Japan.

However, Zhuge Liang certainly didn't know what the reaction armor or mother's clothing was. He didn't want this function to be used, because it was disposable and was too unprofitable, and it would leak if it was shot through.

After arranging everything, Zhuge Liang also booked time with them.

Because they were messengers who were rushing to the road, if there was no accident, two days later, on May 14th, they had to find Guan Yu's troops and establish contact. If the enemy along the way had to patrol ships on the Yellow River, the distance to drift was relatively short, and if they had to cross the mountains, they would have to add one more day, so they would have to ensure that they were delivered on the fifteenth day.

The secret envoy team had no objection to this request, and all issued military orders, saying that they would contact Guan Yu on May 15th. If they could not contact him, they would probably not have the chance to enforce the military law, so they must have died halfway.

...

The words are divided into two ends.

Zhuge Liang tried to re-establish contact with Guan Yu through the Anyi-Dayang County road and explored the way for Guan Yu's retreat route.

In the past two or three days, Zhang Liao and Jia Xu will not be idle either.

It was also on May 12 that Zhang Liao was very unwilling to accept it in the morning because Wei Xu returned with his defeated soldiers last night and brought back the bad news that Liu Bei's camp sent "at least ten thousand reinforcements to assist Anyi".

He also told Zhang Liao that one-third of the troops sent to monitor were lost. He and Hou Cheng led six or seven thousand people to carry out this task, and more than two thousand people were lost.

Zhang Liao asked with a stern face: "I asked you to conquer the squads and snares, and most of them are cavalry. When encountering strong enemies, they can avoid war. Why are there so many losses? Advance easily and retreat easily without practicing military law? How can you convince the public? People come, drag Wei Xu down and take the stick to twenty to warn others."

Wei Xu begged for mercy with a bitter face: "General Zhang is not my business. Hou Cheng went to intercept the enemy. I just helped him to gather the defeated soldiers. Hou Cheng could have retreated, but when he saw that he might not be able to defeat the formation battle, he became greedy and unwilling to leave. He tried to fight against the enemy. Unexpectedly, he was shot down and captured by the horse, otherwise he would not have been defeated so thoroughly."

Hearing that Wei Xu lost was understandable, Jia Xu also asked him for a love affair: "Wenyuan should not be impatient. It is because there is a reason for the matter, but it is better to carefully interrogate and understand the enemy's situation. Just write down the blame and let him make meritorious service."

Jia Xu said, turning to Wei Xu: "Let's talk about the scale of the enemy? How many cavalry and infantry are there, and how many warships are there? They have all been defeated in such a battle. If they don't see these things seriously, they deserve to be punished.

Also, what is the specific situation when the general Hou Cheng was captured? The enemy general's martial arts were really extraordinary? Or was it only slightly stronger than Hou Cheng? Who were the leader of the enemy's army, and who were the vanguards? Did you find out any of the followers? Have you caught the enemy prisoners of war and tortured them to the question why they sent troops so quickly?"

Jia Xu asked very carefully, and at first glance he was a very organized and meticulous person.

In order to avoid being beaten and punished, Wei Xu also told everyone he knew about it. He also found Hou Cheng's personal soldiers who had seen Hou Chengdou at the scene and described it carefully.

Jia Xu knew that the generals led the troops were Wu Ban and Zhang Ren, and they passed in their minds.

He thought to himself that Wu Ban had little contact, but he also knew that during the Northern Expedition of Liu Bei three years ago (194), he took on the feint attack of Longxi in Qishan and Tianshui. The record was mediocre, so he should have been the main nepotism.

As for Zhang Ren, Jia Xu also admitted that Zhang Ren did have a set of historical records in the camp defensive battles, whether it was with Guo Si or Han Sui, and Zhang Ren's two camp defensive battles, and Jia Xu knew it in his heart.

Judging from this personnel structure, Jia Xu's first reaction was: Liu Bei sent Zhang Ren to defend Hedong, rather than sending reinforcements for Guan Yu to attack. Maybe he still hoped to replace Xu Huang into the offensive camp and cooperate with Guan Yu directly to let Zhang Ren take on the heavy burden of defense.

Otherwise, there is no reason to send a defensive general to participate in an offensive battle.

As for Wu Ban, it must be used to ensure that the loyalty of the Hedong region to Liu Bei is not caused by being bribed by the enemy or other unexpected situations. It is normal for the princes to send their relatives to positions with additional requirements for loyalty.

"Is Liu Bei just adding troops to Guan Yu and replacing the current Xu Huang with defensive troops. As a result, it happened to be a coincidence that we bumped into each other, which led to the sudden arrival of enemy aid, which made it difficult for Anyi to conquer?" Jia Xu couldn't help thinking so.

From the personnel and affairs of Wu Ban and Zhang Ren, there is no other threat.

Jia Xu could not see the problem, so he had to observe the record of Hou Cheng Dou General in detail.

After hearing the escaped personal soldiers, Hou Cheng seemed to be injured before he could catch the enemy, and was captured with one move, as if he had been hit by a hidden weapon first. Jia Xu interrogated the details, and the personal soldiers said that the enemy general was extremely tall and ferocious, at least eight feet tall.

As soon as these few details were collected, Jia Xu's pupils instantly shrank a few times, and he murmured: "It's extremely vicious and tall, and his martial arts are so high that he can knock down Hou Cheng with one move. That's either Zhang Fei or Dian Wei."

Zhang Fei’s famous generals in the world cannot hide their names, and he also uses hidden weapons. That’s Dian Wei? Dian Wei is there, is it because Li Suqin led the army to aid?!"

Jia Xu knew Li Su very well. This guy is protected by Zhao Yundian and Wei Zhoutai. Sometimes there are even several bodyguards at the same time, and even Ma Chao has made guest appearances.

When Jia Xu thought of Li Su appearing again, he felt a chilling and cold wind in his bones for no reason.

Regarding the Yin people in the world, Jia Xu has never been afraid of anyone, and Li Su is the only exception.

Zhang Liao looked around and was secretly surprised. It has been several months since Jia Xu defected to Lu Bu. Zhang Liao thought he had seen Jia Xu in various states, but he had never seen Jia Xu's subconscious fear from the bottom of his heart.

Zhang Liao couldn't help but persuade and comfort: "Sir, don't you be surprised. Didn't you hear that Liu Bei was preparing for the throne ceremony when he sent Guan Yu to attack Luoyang? The previous information also said that Li Su, Xun You, Zhong Yao and others were all in Chang'an, and the matter was complicated.

When Liu Bei sent this reinforcement army, Hedong had not yet been attacked. How could he send important officials like Li Su to come in such daily defense changes? I heard that last month, the General of the Cavalry asked Chen Kongzhang to condemn Yuan Shu for being the emperor. After the first to condemn him, he sent someone to pretend to go to Chang'an to enthrone Li Su.

He promised in the name of King Yan that he would be appointed as the young tutor after King Yan ascended the throne. The envoy also confirmed that Li Su was in Chang'an. Such an important official would not perform such a small task."

Zhang Liao's words also involved a funny little story. It turned out that last month, Yuan Shao quoted the Dianxing Youfu Theory to build momentum for Liu He ascended the throne and became emperor, so he was bored to give Li Suyao a promise in order to appear more decent.

In fact, Yuan Shao also knew that Li Su would not be an official, but his attitude of respecting wise men was to be put on, similar to those who had to change the dynasties in history, after the dynasties changed, they had to change the titles of Confucius slightly. Those who were immortalized and saints in the previous dynasties also had to change their titles to show the new dynasty and new atmosphere.

Li Su is a person who argued that Liu He and Liu Bei's orthodox nature, so of course he also had to do it (similar to Guan Yu changing eight titles in the Song Dynasty, two times each in the Yuan and Ming Dynasties, and ten times each in the Qing Dynasty. The only difference is that Li Su is still alive)

It is said that when Yuan Shao's envoy was sent to Chang'an to act, Liu Bei heard about it, but Liu Bei did not kill the envoy, but just mocked him contemptuously: Spicy! Why are you still a young tutor? Even though he knew that Boya would not follow you, he would be the grand tutor directly, and he would never be willing to make it bigger in his dreams.

Li Su was also present at the time. After hearing this, he felt a little awkward. He always felt that it was similar to Liu Bang's tone four hundred years ago, "What is the fake King of Qi? If you want to be granted the real King of Qi."

Fortunately, the situation is different, and Li Su's personality is also different.

I won’t say much about these episodes, just saying that after hearing Zhang Liao’s reminder, Jia Xu stopped his inner fear and quickly returned to his calm attitude, twisting his beard to hide the embarrassment just now:

"That's right, if Li Su comes, it's more than 10,000 people. With Liu Bei's current strength, it's impossible for Li Su to supervise the army by sending less than 30,000 to 50,000 troops. It's a difference between me, but as long as Hou Cheng is knocked down, Dian Wei is really Dian Wei, who else has such great face to let him guard?"

Zhang Liao: "Hou Cheng's personal soldiers just now said that "Dian Wei" was a false name for Wu Ban when he went out. Maybe he was the one who protected Wu Ban? After all, he was Liu Bei's wife and brother-in-law. His dignity and treatment cannot be judged by official positions. Liu Bei attaches great importance to relatives and friends.

Moreover, maybe Wu Ban was greedy for merit and had low martial arts skills, so he was a playboy. So he forced the powerful general to make contributions on his behalf by impersonating his name, so that Liu Bei had an excuse to promote him more and get promoted faster!"

Zhang Liao obviously looked down on those generals who climbed up with nepotism. He was not rich and relied on fighting and promotion. He became angry when he thought of those families.

Jia Xu was stunned and then laughed at himself: "Wenyuan, you can see this clearly. I'm actually dark under the lamp. Yes, Wu Ban, as the son of Wu Kuang and Liu Bei's wife and brother-in-law, is indeed reasonable. If Li Su doesn't come, no one else will be treated like this."

After untiing this knot, Jia Xu asked about some information about the recent deployment of the enemy's troops.

Wei Xu didn't know about it, after all, he fled back as soon as he retreated, so he had to ask the people sent by Zhang Liao to meet him later and the new sergeant scouts.

Therefore, Jia Xu effortlessly noticed the latest defense results of the Anyi defenders.

After thinking about it, Jia Xu couldn't help but smile: "Is this the momentum of slashing the corners and letting the city and the dock water village help each other? They are really the kind of rubber pillars. The water village outside Anyi City is low-lying, and it can be submerged with a little water storage.

Even the truth that Wei Huanzi, Han Kangzi, could understand during the Warring States Period. Zhang Ren still couldn't understand. He was really a person who didn't read history. The seven hundred years of experience of the ancients were there to let you learn from you but not learn, and you deserve to die."
