Chapter 141 Computer Basics Machine Gun vs. Cavalry

Zhang Zhimu rushed to the lecture hall and began to teach everyone a course on pulse and digital circuits.

After summarizing the content of yesterday's lesson, Zhang Zhimu will introduce you to analog signals and digital signals and their differences.

The characteristics of digital circuits are that the binary 0 and 1 represent the false and true of the logical values, and we use the electronic devices "off" and "on" to express them. He also talked about the concept of "number system", as well as the carry rules and weighted expansions of decimal, binary, octal, and hexadecimal.

He also talked about the encoding technology, focusing on the 8421 code in the BCD code that uses four-digit binary numbers to represent a decimal encoding.

Combined with the circuit, he introduced the concept of gate circuits to the home, and told you about the most basic same gate, NOR gate, and the OR gate, as well as the composite logic gate on this basis, such as AND gate, OR gate, OR gate, XOR gate, and OR gate.

Zhang Zhimu knows that today's lesson is also boring for these people, but this is the foundation and must be explained clearly.

After the lunch break, Zhang Zhimu told them the standard system of logical functions and the concepts of the maximum and minimum terms of logical functions, truth tables and logical functions, as well as the methods of filling in the truth table with logical functions and writing logical functions with truth tables.

Zhang Zhimu knows that everyone will not be able to digest so much content in one day, especially these people are completely exposed to a new field, and they will definitely be very uncomfortable. However, I really didn't have much time to spend in lectures, so I gritted my teeth and told you about three simplification methods of logical functions: formula method, Carnot diagram method, and list method.

Seeing that everyone was barely taking notes, Zhang Zhimu said: "I know that it is impossible for everyone to digest all the content I talked about today in this day and grasp it very clearly." We'll leave two days for you to digest the content slowly, and on the third day I'll continue to tell you about the new content. I know that this is very boring right now, but just like when we first started working on tubes, we will get through this difficult period and a new world will be revealed to you. You are some of those who are ushering in a new dawn. I can tell you that your work will be hard, but it will be worth it compared to the joy it brings you. ”

What Zhang Zhimu didn't say was that these were the essence of how many of the best people in his previous life had worked hard to research, and you all got it in such a short period of time. Zhang Zhimu knew that he had to grit his teeth and introduce these basic knowledge to them, as for what kind of brilliance they could create after receiving this knowledge, it would depend on their creation.

With patience, Zhang Zhimu answered everyone's questions for a while, and then hurried to the command center. Zhang Zhimu really wanted to know about Liu Yun and their situation.

Zhang Zhimu entered the command hall and saw that in addition to Chen Yufeng and Ouyang He were here, Yan Boju, Yan Xing, Li Yan, Yang Jing, and Li Wei were also here. Zhang Zhimu knew that they knew that Liu Yun and they were fighting outside, so they must be very curious to know the specific situation.

Seeing Zhang Zhimu, Chen Yufeng said: "Liu Yun, they can bypass naturalization tomorrow and march to Daqingshan." This little rabbit cub also sent a telegram saying that he wanted to conquer the Naturalization City, but I didn't agree. We believe that there is no problem with naturalization with their forces and weapons. The problem is that after the defeat, Prince Tori can't hold it on his own, and we are not ready to send troops. ”

"I think they won the battle, and they also tried to beat the Mongols. The fighting spirit is not ordinarily high. Ouyang He seems to be in a good mood.

"Yes! For many years, we have been repeatedly tolerating the north, and this time we have also taken a bad breath. Li Yan was also very excited, "Mr. Zhang, shouldn't you drink some wine tonight?" ”

"That's right!" Zhang Zhimu said, "We should have a good drink tonight." ”

Chen Yufeng said: "I think this Li Kui is the oldest, and he won't persuade Liu Yun and them. So magnificent. ”

"Come on! Mr. Chen, as soon as Li Kui heard that there was going to be a war, he was more energetic than anyone else. He can still persuade Liu Yun, it would be good if they didn't persuade Liu Yun to secretly naturalize! ”

Yan Xing's words drew a burst of laughter.

Now Liu Yun really wants to bring down the naturalization, in Liu Yun's opinion, this naturalization is a world of difference compared to Tongguan, and the remnants of the soldiers who escaped and returned have long lost their fighting spirit. With just a few shots, they'll be honest.

When Liu Yun and the others were still some way away from naturalization, they sent cavalry scouts to go out in front of the two wings in front of them to expand the scope of reconnaissance. Li Jing also led a team of people to fight the front station. Li Kui saw that Li Jing was taking people out, so he took his own soldiers and went with Li Jing.

When I arrived on the grassland, I saw Li Kui's experience. When he arrived at the front, he immediately said to Li Jing: "Boy! I think you're quite clever, and your Uncle Kui will teach you some skills today. ”

Li Kui didn't care what five levels Li Jing had gone through and what six generals he had been, and he was not polite at all. Li Jing also likes Li Kui's boldness, and besides, many of his special forces were selected from Li Kui's team in Niutou Mountain. The two of them had a good relationship. Li Jing was also very convinced by Li Kui, "Uncle Kui, it's all up to you today." I don't really know much about the grasslands. ”

Li Kui reassigned the position of the prospecting horse that came out. He said, "You see, if there is an ambush of cavalry in the steppe, the place where they are ambushing must not be too far from the road we are taking, nor too close. Too close their horses could not run, and the impact of the cavalry could not be exerted. If it is too far away, the attacker will be prepared, and the suddenness of the attack will not be good. That's how the location of the scouts I sent out was determined. Got it, kid? ”

"Got it!" Li Jing hurriedly flattered, "It seems that Jiang is still old and spicy." ”

After walking for almost a day, nothing happened, and the sky on the grassland was also very good, it was really blue sky and white clouds. The grass in this area also grows very well, and in some places, people riding on horses can only show a horse's head and a human figure. Li Jing was in a good mood, "Uncle Kui, you see there is a dirt hill in front, let's camp there tonight." I heard Prince Tori say that one day he will be naturalized. ”

"Okay!" Li Kui replied a little absentmindedly.

Seeing that Li Kui's mood was not high, Li Jing said, "Uncle Kui, you see how good the day is today." We'll be in Daqingshan in a few days, so you should be happy. When you go to Daqingshan, can't you have a heart-to-heart drink? ”

"Humph!" Li Kui said: "I can't see it, what's so happy today? ”

Li Jing heard that there was something in Li Kui's words, and asked, "What, what did Uncle Kui see?" ”

"Nope! I think it's a little wrong. Li Kui said.

Li Jing understands that these battle-hardened people feel very revealing, but they often have no reliable evidence and are often ignored. Li Jing sent several more groups of cavalry to expand the reconnaissance area to the two flanks.

Li Kui saw a tree next to him, so he asked one of his personal soldiers to climb the tree and use the telescope to look to the left. But the soldier looked at it for a while and said, "I can't see anything abnormal." ”

Li Kui was still not at ease, and said, "Boy, you take people slowly, I'll go to the front to have a look." ”

Li Jing said, "No, Uncle Kui. The ones I sent out just now were all our special forces. ”

"Humph! Commando! Li Kui snorted with his nose and said, "When you go to the grassland, you still listen to your Uncle Kui, and promise not to suffer." After speaking, Li Kui led a few people to the left, and quickly drowned on the grassland.

Li Jing had no choice but to be patient and slowly walk forward with the avant-garde. Because the carriage on the grassland can't go fast at all, one is that the grass is thick, and the other is that the soil is soft. Especially heavy cars, although they are all rubber wheels, there is no way to do it, so you can only walk slowly.

Suddenly, Li Kui came back with people, not only did he bring the people back, but the scout horses who went out to scout on the left flank also came back. Li Jing knew that there must be something going on, and asked, "What's the situation with Uncle Kui?" ”

"Humph! I guessed it. There is an ambush ahead. Li Kui wiped his sweat and said, "Send someone to find the right-wing probe horse." Let's go back. ”

Li Jing hurriedly sent someone to find the right-wing Tanma, and then asked, "Uncle Kui!" Tell me about the situation. ”

"I just feel a little wrong!" Li Kui and Li Jing walked back with the people, and said: "The place we want to camp in favor of is the ambush point they set up, and they also thought that if the team of people and horses came to camp here, they would definitely rely on a high place." So they ambushed the team here. I looked through my binoculars and didn't dare to go forward. I don't know how many of them there are. I don't know if they found out we didn't. However, our brigade will definitely send people to follow from a distance and keep track of their whereabouts at any time. ”

Li Jing said: "Let's rush back as soon as possible, choose a place to set up a position, and we can have a good fight with them." ”

"yes!" Li Kui said with some excitement, "I thought I wouldn't be able to fight this time." This time it's good! ”

"Uncle Kui, I think you're not afraid of chaos!"

"Little rabbit, I think you're even happier, and you're talking about me."

Li Kui and Li Jing walked more and more like they had picked up a treasure.

Liu Yun and Liu Chenghuang saw Li Kui and Li Jing come back, and knew that there must be a situation. Liu Yun: They are not afraid of the situation, but they are afraid that the situation is unclear.

After listening to Li Kui's report, Liu Yun immediately stopped the marching procession and notified the two cavalry commanders and the commander of the transport regiment to come over for a meeting.

After introducing the situation, Liu Yun said: "We are now in the open place, I think we will put ourselves in a position with them to see what they can do." The place we had just come to was a mound of dirt, and we pitched a stockade around it and waited for them. They must have a large army of men there ambushing us. So it was they who found out about our actions, and it took time to make temporary changes, so we first put the carriage in a circle, and then set up the other facilities. Now immediately retreat and arrange. ”

In order to deal with the emergency, Liu Yun and the others retreated to the bottom of the big mound, first connected the carriage end to end, and arranged a defensive circle. Then both heavy machine gunners and artillerymen went to the top of the mound to build fortifications. The sappers unloaded the special tripwire equipment from the cart. This is a section of 1.5 meters long large angle steel, one end is polished into a point, and the other end is connected to a thick wire rope with a steel ring, each section of wire rope is ten meters long. Not only do they have one section, but they all have easy-to-connect loops, and several sections can be connected together. In front of the battle, they used sledgehammers to nail the angle steel into the soil, leaving only a 400-meter-high wire rope to tighten and make a tripping rope. Since it was a standardized piece of equipment, the wires were wrapped around and placed on the cart, and the tripwires were quickly laid out around the perimeter, and these tripwires were between 100 and 30 meters away from the infantry line. Between a hundred and fifty meters, the sappers began to lay mines in large quantities. Most of them are tripping mines. There are also places where remote-controlled mines are arranged. In the middle of the tripping horse, everyone began to dig the horse pit again. It was rows of pits a foot square and a foot deep. For the role of such pits. Liu Yun and the others really knew their usefulness, and they used such a pit to slow down the impact of the Mongolian cavalry and defeat the Mongolian cavalry to the ground.

The teams of the kiln gang are equipped with folding sapper shovels. This is designed by Zhang Zhimu based on the sapper shovel in his previous life, and it is usually very small when folded and does not take up much space. Not only can it dig the soil, but it can also be used as a weapon to chop and chop, which is very popular with officers and soldiers. This thing is indeed very convenient to use.

However, there were no trees here, so there was no way to make a rejection horse, so Liu Yun arranged for others to start earthwork. These soldiers were trained in earth work. They first dug a single bunker for each of them, then dug through the adjacent bunkers, and finally dug trenches, and the excavated earth was piled up in front to make a retaining wall. After the trenches were dug, the trenches began to be dug again. Because the bows and arrows of the Mongol cavalry were very powerful, it was best to move in the trenches in the positions. After digging the ditch of the kiln man, he dug some deeper pits. Hide your camels and horses in cover to reduce their injuries from bows and arrows.

It was always dark, and the scouts sent out did not find out the news of the Mongol cavalry. The kiln people rested after dinner, did not dare to delay any longer, and began to build fortifications under the calcium carbide lamp. A total of two trenches were built in front of and behind.

Li Kui was a little dissatisfied and said: "We are all cavalry, how can we drill holes like rats, if this is spread in the future, you must not say that you are cavalry." Can't afford to lose people. ”

Liu Yun and Liu Chenghuang were not angry. Liu Yun said: "Mr. Zhang said that whether it is a black cat or a white cat, catching a mouse is a good cat." ”

Li Kui said: "I said Liu Yun, don't let everyone get it too late." The Mongols were very good at night raids. ”

After listening to Li Kui's words, Liu Yun called the commander of the engineer company and said, "Brothers, work harder, arrange a little more remote-controlled fire oil bombs for me near a hundred meters away from the battle, and when the Mongols attack at night, they will be lit for lighting." ”

The engineer company commander said, "Let's keep the oil bombs for later." If you want to illuminate, we can use electric ** to detonate and ignite the fierce fire oil. We brought a lot of bamboo tubes, which were just filled with fire oil. The commander of this engineer company is also a veteran of Yaogang, and they used bamboo tubes to make fire oil bombs in Shaanxi County and Hanguguan, so they are very good at using this thing. ”

Liu Yun listened to the words of the engineer company commander, and his heart moved. He felt that it was still the original veteran, and he could use it when it was critical. Liu Yun instructed: "Don't start a fight, don't light it all at once." Otherwise, if they attack a few times, we will fight in the dark. ”

"Don't worry!" The engineer company commander finished speaking and left.

When it was almost over, Liu Yun asked everyone to hurry up and rest.

Liu Yun arranged a typical circular position, and he arranged Prince Tori's team in the innermost, although his arrangement was repeatedly opposed by Prince Tori. But Liu Yun still insisted on doing so. Because their muskets couldn't compare to the automatic rifles of the kiln gang team, Liu Yun didn't want them to suffer losses now. He looked around, relieved. Go back and rest too.

Besides, the three princes of the Sunit tribe were really not ordinary people, after they joined the naturalized defenders, they carefully studied the route of Liu Yun and their caravan, and concluded that they must have gone to Daqingshan. So they kept sending people to track the caravan's whereabouts. They decided to set up an ambush in front of the caravan to the camp before naturalization, because it was close to naturalization, and the caravan would not be too vigilant before naturalization. Finally, according to the itinerary, the caravan will arrive at a high post at night. As a general rule, caravans would camp at high posts. So they laid an early ambush on both sides of the caravan's passing.

This time, more than 10,000 people from the Sunit tribe came, and more than 10,000 people came out from the naturalized defenders, and they all felt that it would be enough to deal with this caravan no matter what.

When Tanma reported that the front caravan of the Han Chinese had appeared, the Mongols were a little excited. The three princes hurriedly told everyone to hide themselves and not make a sound. The third asked the second: "Hi! There must be a lot of good things in the caravan, but I don't know if there are Han women. I heard the old people say that the skin of Han women is like snow, and it is particularly smelly. ”

The second child smiled and said, "I didn't expect you to have this thought." Come back to you and take care of people. Don't make something bad about it. ”

But they waited for a long time, and they didn't wait for the caravan of the Han Chinese. Later, it was reported that "the avant-garde of the Han caravan has gone back." ”

The Mongols found it strange that they did not know that their ambush had been exposed. The third child said: "Are those naturalized people exposed?" ”

However, the naturalized people complained that it was the Sunit who exposed their whereabouts. The two sides argued for a while, and the second of the Sunit people said, "Okay, we are all Anda, so don't complain about each other." Since these Han people have come to our grassland, they can't escape. Let's see where they go. I will know when the horse comes back in a while. ”

The naturalized people don't want to see the good things of their hands and run away like this.

Soon the horses came back one after another to report that the Han people were not far in front of them and began to set up camp. Now they're forming a circle of wagons and starting to set up camp.

The third elder of the Sunit tribe said, "We rushed in while they were not ready." ”

The second said, "No, their people are concentrated, and they have muskets." The obstacle formed by their cart was not worth mentioning, but if it stood in the way of our horses, their muskets would work. We're not prepared to suffer a big loss. I'm going to look into it again and see what they do to stay here instead of running away. ”

One of the naturalized leaders said, "Haha! They know that they can't run away from running on the grassland. There is no way to do it. ”

After these people quietly scouted around and came back, the third elder of the Sunit tribe said: "I see that they dug a circle of ditches, I don't know what they are for?" ”

The second child said: "On the steppe they couldn't find anything to cover our Mongolian arrows, so they had to dig a ditch and hide." ”

The naturalized leader said, "Let's rush in while it's still dark!" ”

The second of the Sunit tribe said, "I can't see it, they are hiding in the ditch, and you see that their soldiers are wearing helmets." It is difficult for our bows and arrows to hurt them, and they can shoot at us with their muskets. We have a lot to lose by hard rushing. We don't do such stupid things. They Han people came to our grassland, and we all had time to clean them up. My idea was that we could use our cavalry to storm their camp at night and take them by surprise. ”

The second child's words were agreed by everyone. The second child said: "From now on, we will not show up in the first half of the night. We waited for them to fall asleep in the middle of the night, and then split up and rushed in. ”

The words of the second boss of the Sunit tribe made these Mongols see the hope that they could kill the Han people and grab the treasure, and they were waiting to do it one by one. They seem to be born to look down on the Han people and hate them.

When they had passed, they divided into four sides and surrounded the caravan's camp. When they approached the camp, they all dismounted and led their horses quietly. Their plan was to scout first, and then attack from all sides, so that the Han camp could be flooded at once.

But what they didn't expect was that when their spies went to reconnoitre, they stumbled. This made these Mongolians unexpected, although they didn't know that it was ** ringing, they knew that it was discovered by the Han Chinese.

So they decided to go on the offensive.

In fact, the observation post on the earthen bag of the kiln gang people had already vaguely seen a large number of people surrounding them with telescopes through the starlight. They didn't say anything, but quietly told Liu Yun. Liu Yun shouted everyone up and came to their respective positions along the traffic ditch. By the time the first ** was sounded, Liu Yun's team was already ready for battle.

When the Mongol cavalry charged quickly, the commander of the engineer company commanded the soldiers and detonated several bamboo shells. In front of the circular position, there was a circle of torches burning, illuminating the front of the position. The cavalry who rushed up couldn't hold back, and they began to stumble. At this time, more than 30 heavy machine guns on the mound began to wield. Roaring heavy machine guns fired strings of fiery bullets at the Mongol cavalry as they approached. The galloping horses were hit by bullets and immediately rolled on the ground, crushing their carrying cavalry to pieces. It is not false that the machine gun is the nemesis of the cavalry. The cavalry's swift charge made it impossible for the infantry to parry, but the machine guns were far faster than the horses. The cavalry horses that rushed over, in the roar of the heavy machine guns, fell in rows, and some of the cavalry who rushed over began to roll continuously about a hundred meters before leaving the formation, and they couldn't see the wire rope tripping rope on the horse. Another thing that slips through the net is the target of the automatic rifle. Due to the heavy machine gunners' hard work, there were not many opportunities for automatic rifles to be used. These water-cooled heavy machine guns, although bulky, had good continuity of fire. You can shoot almost non-stop.

These proud Mongolian cavalrymen, who died today, don't know how they died. In front of the ring, horses and corpses were soon piled up into a crater.
