Chapter 986 Untitled
When the sun's shadow turned to the west, the two people on the top of the city slowly stood up and looked towards the city. The messy city had become much tidier and looked brand new.
In order to eliminate the remaining enemies and for health and epidemic prevention, the Julu sergeants cleaned every corner after entering the city. The bodies of the people who died in the city were collected and burned together, and the ground was also cleaned.
Quicklime and large bags of activated carbon were poured into all the wells in the city. The relatively intact houses in the city were cleared, cleaned and limed to prepare for use as housing or warehouses. The carpenters of the dilapidated houses began to repair them in just half a day.
, a huge city was tidied up.
The logistics camps and the pottery battalion went straight to the kiln in the city without stopping after entering the city, preparing to borrow the kiln in the city to open the kiln and bake pottery immediately. The people in the carpenter battalion collected wood everywhere and carried out work such as repairing houses and vehicles.
Iron tools such as hoes and shovels were collected. The rebel army did not know how to use these iron tools, but in the hands of the Julu Army, these iron tools could be made into weapons at any time.
Also, the butcher camp has to deal with the horses that died in the battle, and the fishing camp is preparing to go fishing. All camps are busy.
There is a little difference in the logistics team. The pottery team brought by Li Mengxi began to bake pottery. In addition to firing pottery, Liu Bei's pottery team also prepared clay to make clay embryos. The reason for this difference is that since the division of troops,
Liu Bei and Li Mengxi each encountered different situations and took different measures.
By the way, before Li Mengxi came, Liu Bei had been holding on for a month and was almost out of food. Liu Bei was lying not to be anxious. Liu Bei was also anxious, but he had full trust and confidence in Li Mengxi. Liu Bei knew that as long as the military advisor
If we bring reinforcements here, there will definitely be no shortage of food.
Not only is there no shortage, there is even meat.
Li Mengxi ordered a turtle as big as a basin to be brought to Liu Bei, and asked Liu Bei if he knew how to stew the turtle.
Liu Bei was extremely surprised to see such a big turtle. Forget it on weekdays, this was war time. How could he get such a big turtle?
In the end, the turtle didn't eat it. Liu Bei felt that it would be a pity to kill such a big turtle because it had to grow old, so he simply continued to raise it.
Soon, the meal was ready. Liu Bei's subordinates had been saving food tightly recently and did not dare to let it go. Now that they had food, they could finally have a full meal.
Li Mengxi is well versed in the method of motivating people's hearts. He knows that motivation must be timely. The more timely the motivation comes, the better. After a good meal, the morale of the soldiers will greatly increase.
Afterwards, Li Mengxi went with Liu Bei to visit the military camp in the north of the city. When they arrived, Li Mengxi saw a small city located in the distance where the village was, but the village had disappeared. Li Mengxi looked at Liu Bei in surprise.
Liu Bei pointed to the location of the military camp and said proudly, "Xi'er, what do you think of the construction of my camp?"
Li Mengxi couldn't wait to go into the stronghold to find out what was going on. When he got close to the front of the stronghold, he saw that there was a trench dug in front of the stronghold. What was strange was that compared with the tall and solid rammed earth city wall that stood up suddenly, the trench in front of the wall was too narrow.
After a while, Li Mengxi keenly discovered this anomaly, and he asked Liu Bei what happened.
Liu Bei smiled. He pointed outside and said, "Xi'er, look, there is a trench two hundred steps in front of our camp. Guess who dug that trench?"
Li Mengxi looked far away, and indeed saw traces of raised soil on the ground in the distance. It was a bit strange. What is the reason for digging a ditch two or three hundred steps away from the camp? It is said that the trench was dug to disrupt the enemy's position and slow down the enemy's attack.
Speed, that's not right. You only need to dig shallow trenches to block troops. It's easy to dig. If it's to block troops, why not dig more trenches to block troops? Why do you see only a few traces of them?
Li Mengxi couldn't understand, so he expressed his thoughts in confusion.
After Li Mengxi finished speaking, Liu Bei was confused. Liu Bei didn't know what the blocking ditch was.
After that, Li Mengxi gave a brief introduction. In simple terms, the so-called blocking trenches, as the name suggests, are trenches that provide obstacles to enemy soldiers. The blocking trenches are just shallow trenches that are not ankle-deep. The existence of such shallow trenches makes the ground
The pits are uneven, and when the enemy troops pass through the ravines in formation, the soldiers' feet will be messy, and the formation will naturally be chaotic.
The principle of blocking trenches is very simple. Liu Bei understood it immediately and imagined it in his mind. Because it is easy to dig trenches, hundreds or even thousands of trenches can be dug. Hundreds of trenches can be dug across the battlefield.
Above, if the enemy wants to pass, they have to jump once after taking two steps. How can the formation be so neat?
Liu Bei was amazed by this simple and clever tactic.
"Xi'er, this is not a trench to block troops, nor was it dug by us, but by the enemy." Liu Bei explained.
"...The enemy dug it?" Li Mengxi suddenly understood. If the trench was dug by the enemy, it would be reasonable. The enemy wanted to use the trench to siege the city and wanted to turn the initiative into a passive one.
Li Mengxi was no stranger to this method of trench siege. Huang Taiji had used it to siege Datong City, and Mr. Li had also used it to siege Huangfusong's camp. However, what kind of person Huang Taiji was, and what kind of person Li was, this tactic was so easy to come up with.
Well, why did the enemy also come up with this tactic?
Li Mengxi asked Liu Bei about his doubts. Liu Bei laughed and said, "No! The enemy didn't know this siege tactic. It's because of our army."
Li Mengxi was even more confused. How could the enemy's siege tactics be related to our army? "What's wrong? There is a traitor in our army?" Li Mengxi blurted out.
There were no traitors, but the enemy army did come up with the trench tactic because of Liu Bei.
Liu Bei's barrier was so tight that the enemy didn't know how to break it, but Liu Bei insisted on digging another trench outside. This was great. As soon as the enemy saw Liu Bei digging the trench, they were immediately inspired and immediately thought of using the trench to counter the barrier.
.
"[Those who are good at guarding, hide under the nine places], that's what it means." Li Mengxi suddenly realized.
The good defenders hide their weapons. The winning troops of World War II hid their radars and the British army hid their tanks. All countries are determined to hide their sophisticated weapons and hide their information as much as possible to avoid being found by their opponents. This is not the case in military competition.
This chapter is not over yet, please click on the next page to continue reading! From Liu Bei's actual combat experience, Li Mengxi had a major understanding of "Good defenders hide under the Nine Earths". Similarly, Liu Bei also learned from Li Mengxi "Resisting Soldiers"
This clever tactic of ditching and communicating with each other makes one plus one greater than two.
When he walked to the place where the enemy dug the trench and took a closer look, Li Mengxi found that the trench dug by the enemy was really terrible. It was shallow, short, messy, and abandoned halfway. He was confused at first, but then he figured out that the workload of digging the trench was huge.
Great, if you want to dig a trench well, you must have enough manpower and tools, and you must have the opportunity to dig the trench calmly.
The siege of Huangfu Song on that day required tens of thousands of Yellow Turban refugees to be called a success. Moreover, the Yellow Turban refugees had many tools and basic construction conditions in their hands. However, it was not expected how much manpower the thieves could have. Even if the thieves had enough manpower, how could they be so powerful?
It is easy to gather enough tools. The enemy army has enough tools. Under the threat of Liu Bei's three or four thousand elites, how can he be allowed to work calmly?
Later I asked Liu Bei, and it was true. At that time, the bandit soldiers numbered only a few thousand, and they lacked tools. Moreover, due to the harassment of arrows, the bandit soldiers did not dare to approach. They only dared to start construction two or three hundred paces away, and the encirclement circle was drawn.
When they were 300 meters away, the encirclement was so huge that the bandit army retreated after only two days of digging.
Li Mengxi raised his foot and kicked the stone into the ditch. He laughed at the incompetence of the rebel army and laughed at the rebel army. They couldn't even dig a ditch well and how could they be worthy of being the opponent of the Julu Army.
——
Liu Bei built the camp really well. The dilapidated and deserted village was turned into a small city by Liu Bei.
Li Mengxi inspected the walled city. The height of the wall was one foot upward. The wall was made of soil, which was thick and solid.
Inside the military village, Li Mengxi seemed to have seen a shantytown reform area. What he saw was a mess of sheds everywhere. The sheds had gathered all the mess. The sheds were randomly propped up with wooden sticks, and they had roofs on them. The roofs of the sheds were connected to the lake.
Li Mengxi first thought that these shed roofs were substitutes for housing. After all, thousands of people were crowded together. The original housing in the village was definitely not enough, and the cost of building houses was high, so
I can only make do by building a rainproof roof.
When Li Mengxi realized that the roof might be used for rain protection, he found the messy roof more pleasing to the eye.
Regarding rain protection, Li Mengxi made some suggestions to Liu Bei. For example, tung oil cloth can be used as a rain-proof base material. Tung oil cloth is too light and cannot withstand strong winds, and the rain-proof effect of soil is poor. Therefore, a layer of tung oil cloth is used as a rain-proof base material.
If there is a layer of mud in the lake, the mud will increase the strength, and the strong wind will be unable to do anything.
After listening to what Li Mengxi said, Liu Bei smiled and said nothing.
When Liu Bei smiled, Li Mengxi felt something was wrong. He scratched his head and looked at Liu Bei doubtfully, "What's wrong?"
Liu Bei smiled slightly and said, "I built this shed not to keep out the rain, but to protect myself from arrows."
"Guard against arrows?" Li Mengxi thought thoughtfully.
Afterwards, Liu Bei gave a brief explanation, and Li Mengxi completely understood the purpose of the roof.
According to Liu Bei, the rebel army had stormed once before. Thousands of archers and crossbowmen were used to throw a hail of arrows at the stronghold in an attempt to consume our troops. At that time, the roof of the shed had been built. After the battle, the enemy's arrow rain
Seventy-eight times out of ten, they were blocked by the roof of the shed, so the enemy's arrow-laden offensive failed to achieve success.
Li Mengxi understood that the roof of this shed was just like the eaves on the city wall, which were used to block arrows from above. At the same time, Li Mengxi remembered that when the enemy and we were confronting each other at a long distance, if the enemy wanted to project arrows at our army,
If the arrow is above the head, it must be shot from above. If the arrow misses, it will inevitably fall from above.
If, during a battle, each soldier is equipped with an iron umbrella to block his head, half of the enemy's arrows will be discarded, and our casualties will be directly reduced by several percent.
The question is repeated. Li Mengxi had previously realized the advantage of the flying saucer hat in blocking stray arrows. The flying saucer hat can be equipped, but the iron umbrella is really unrealistic. After Liu Bei's actual combat experience, whether it is an iron umbrella or a shed roof, this
Such tools are not practical for individual soldiers, but they can be used as fortifications.
What should I call this kind of shed roof that is specially used to block arrows? Li Mengxi thought, it might as well be called a "war shed".
There are arrow towers at the four corners of the military stronghold. The arrow towers are too high. Compared with the ten-foot-high earthen wall, the arrow towers look very abrupt. The height of the arrow towers is at least six feet according to visual inspection. This is six feet, which is as high as the sky.
The fundamental reason why the arrow tower could be built so high in just one month is that Liu Bei built the lower part of the arrow tower with earth. After it reached a certain height, he then used wood to build it up. The soil base is strong and stable, but the higher the base, the harder it is.
Fortresses, and wood is easy to erect, so it is suitable as a top-level building, but the foundation of the wooden structure is unstable and needs a stable foundation. The combination of these two, with soil at the bottom and wood at the top, is the most cost-effective option. It can be used in the most cost-effective way.
The easy way to reach the highest heights.
Li Mengxi could always see knowledge in his eyes. After taking a look at the Arrow Tower, he felt that he had encountered knowledge worth remembering.
The civil structure of the arrow tower reminded Li Mengxi of the Yellow River ferry. It is easy to build a pontoon bridge but difficult to build a solid bridge. But when the river is too wide, the reverse is true, and it becomes more difficult to build a pontoon bridge.
At the Yellow River Ferry, craftsmen used a clever strategy. The craftsmen extended the bridge piers into the river for a long time. This reduced the width of the river in disguise. You must know that when the river is wide to a certain extent, the length of the bridge deck will increase every time.
meters, the difficulty of erection increases greatly, and the width of the river is reduced. Every reduction of one meter greatly saves construction costs.
Li Mengxi still remembers the structure of the bridge at the Yellow River ferry. The structure of the bridge at the Yellow River ferry is decomposed. From the river bank to the center of the river, there are permanent embankments made of earth and stone - wooden piles buried in the water.
The solid bridge - a pontoon bridge built on a ship with ships as pilings - to the middle is the suspension bridge.
The engineering idea of the Yellow River Crossing Bridge is very clever. The water becomes deeper and more rapid toward the middle of the river. Therefore, near the shore, where the water is neither deep nor urgent, you can choose to build a permanent bridge embankment with earth and stone, and then go inward a little further.
, the water is deep and the current is strong, it becomes more difficult and costly to build a bridge with earth and stone, so at this time, the most cost-effective option is wooden pile piers. Further in, the water is deeper, and it is so deep that there is no way to go in.
Piles have been buried in the water several feet deep, so at this time, pontoon bridges are the most cost-effective option. Further in, we reach the center of the river. The water flow in the center of the river is extremely fast. If we continue to use pontoon bridges,
The floating boat will bear the huge impact force of the water flow. At this time, the suspension bridge built in the air just avoids the impact of the strongest point of the water flow.
The idea of the Yellow River Crossing Bridge is the same as that of the six-foot arrow tower built by Liu Bei. As the project is taller, longer and deeper, the difficulty of construction will gradually increase. Therefore, if you want to reduce the difficulty of construction, you should gradually change as the project progresses.
Engineering technology.
On the six-foot-high arrow tower, Li Mengxi glanced down, feeling like he was overlooking the mountains.
There was a geared crossbow, also known as a sniper crossbow, set up on the arrow tower. Li Mengxi went up and fiddled with it for a while. He adjusted the crossbow to a shooting angle of about 45 degrees, pulled the trigger of the crossbow, and the crossbow arrows flew out with a whoosh and disappeared.
.
Li Mengxi couldn't help but groan, "With the power of the big yellow crossbow and the extra six feet of height, how much can the shooting distance be increased?"
"Four hundred and twenty steps." Liu Bei replied from the side.
The four hundred and twenty steps were tested by Liu Bei after the war.
With a height of six feet, the shooting range is increased by more than 150 steps.
