When Li Huan and Company Commander Zhang chatted and walked, and when they reached the end of the airport runway, there were already soldiers there who had set up torches and started working. The little soldier surnamed Song was directing everyone, inserting the torch into the ground, inserting a rough outline - Li Huan roughly looked at the outline around the torch, which should be the location of the mirage bones they found underground. Under the light of the torches, the little soldiers are digging down little by little with their tools!

"If you see it, just say it, don't let heavy construction machinery be used, our troops are also very combative. Brother Li, you don't have to panic, look at this progress, in about two hours or so, the skeleton will be safely dug up. Company Commander Zhang looked at his soldiers carrying out the excavation work in an orderly manner, and was a little proud: "If we don't talk about digging companies, then we will be re-elected, and second, probably no one in the entire military region will dare to recognize the first, and we can dig a trench one kilometer deep within an hour." But I gave them a special order to be careful when they give birth, lest they break the skeleton, and we don't know what clues the skeleton can have now, so it's always right to be careful. ”

After speaking, Company Commander Zhang shouted: "Be careful for me, avoid the bones when you dig up, and finally clean up carefully, that guy will mess with me and go back to confinement for a week!"

"Company commander, don't worry, we don't dare to say anything else, but if you want to dig a pit, I admit the second, then no one in our company will dare to admit the first. You too, if we had said we would have kept it, we wouldn't have buried it again. Look at what we buried with our own hands now, we have to dig it up with our own hands, alas, and blame us for the quality of our work, which is too good for us, and we have re-pressed it after burying it, and now it is very tiring to dig. ”

"Company commander, can you tell us what this skeleton is digging up for? I think it's like a broken man's bones, oh, no, it's not a dead man's bone, it's a bone shelf. But this bone frame is an animal, it is not a fossil, if it is a fossil, we can dig it back and donate it to the country, what do you say we dig it for?"

"Company commander, don't look at it, don't stand by and watch, don't you always tell us that we dig pits slowly? Then you come and show us in person, you come to demonstrate in person, won't our digging progress be faster? Let us also learn the company commander's excavation method, maybe our future work tasks will be completed more smoothly, brothers, don't you?"

"Yes, yes, you can also come down and show us in person, don't you always say that we are slow? Let's see what it looks like to move fast, we can't use heavy machinery now and have to rush to work, we just need a master like you to guide us! Company commander, don't be polite, come down and show us how to demonstrate!"

Company Commander Zhang was coaxed by a small soldier, and smiled: "Then Brother Li, you wait, I'll also go to help, let's speed up the progress a little, dig up this skeleton early, and you can find clues sooner." ”

"Okay, let's dig it up. Li Huan also nodded.

"You?" Company Commander Zhang was stunned: "You better rest, you people who do confidential work, I know that the nature of your work is different from ours, you see that you have fine skin and tender meat...... It's not that I look down on you, we mainly do manual labor, you said that you have dug up experience all day long in this barren mountain and wilderness, you still don't want it, we don't lack many people and you don't lack this one, and then flash your waist, so many things are coming...... Just watch us dig. ”

"Why do you think I have fine skin and tender meat?" Li Huan couldn't cry or laugh.

The word fine skin and tender meat is the first time Li Huan has heard it used on himself. Touching his conscience, his body after being genetically modified and tempered by aura has a perfect posture, and the explosiveness of each muscle is very strong. Even if he doesn't use aura, ordinary people can't catch up with him. How did he get to this place with fine skin and tender meat? Moreover, he had been running around all the year round, and his skin had been sunburned to a healthy wheat color, so no matter how you looked at it, it had nothing to do with that fine skin and tender meat. But you can still look at these engineers who have been working outside all year round, their muscles are more developed, and Li Huan's skin is tanned, they are really tanned. Especially when they were working, the ground had been dug down to a depth of about a meter, and in the sweaty labor, the beads of sweat oozing from their skin reflected the torches, making their skin look even darker.

Compared with them, Li Huan is probably a little white face.

"Haha, this is a specialization in the art industry. Company Commander Zhang said, then took a shovel from the little soldier's hand and went down the pit himself.

"Don't, I can't stand the word fine skin and tender meat, give me a shovel, and I'll be with you. Li Huan said that this also went into the pit: "Although as you said, I do some confidential work, but it doesn't mean that I can't work." If you want to dig a pit, I really haven't confessed to anyone, it's not that I said that if I want to dig seriously, none of you here can catch up with me, do you believe it or not?"

Everyone didn't speak, these little soldiers dared to talk nonsense to their company commander, but they didn't dare to be disrespectful to this young officer who suddenly appeared, but they looked at Li Huan's eyes with a look of disbelief.

"Hey, look at your unbelieving looks, or let's make a bet?" Li Huan smiled: "I'll compare with your company commanders to see who can see the bones first? If you lose, after I take you out safely from here, I will invite you to eat a big meal for a month." If your company commander loses, hehe, then you'll have to admit it to me. ”

Then, Li Huan stretched out his hand to a small soldier: "Give me your tools." ”

"Company commander...... "That little soldier is in a dilemma.

"Hehe, Brother Li, since you want to bet with me, then I can only treat you as a soldier, and I don't treat you as a person who performs confidential tasks, and our troops are not ambiguous in betting. Let me tell you first, if you lose, you will have to invite us to a month's dinner, and those of us who usually work in the mountains have a lot of food!" ”

"Okay, that's what I said, as long as I lose, I'll treat you to a big meal for a month, as long as you can order it, I'll get it, but this chance is very small. Li Huan laughed.

The little soldier had no choice but to give his tools to Li Huan, and then asked in a low voice: "Will you use this sapper shovel?"

Li Huan took it and took a look, the domestic 80-type sapper shovel can be called a generation of artifact!

"The Type 205 sapper shovel is large and inconvenient to carry. It is generally inserted in a well-made backpack, or in a fixed buckle in the backpack, such as the 65-type paratrooper backpack, the 91 carrying gear backpack, and the 01 carrying gear backpack have a ring buckle directly inserted into the sapper shovel, which is more convenient to carry, and it is not affected to sit down and rest. There are a lot of external attachment points on the outdoor backpack, and there is basically no problem with inserting a 205. Li Huan pinched it: "Okay, that's it." ”

Sapper shovel, improved by three generations of shovels to fold twice, the handle is like a triangular streamline, with shovel, pickaxe, crowbar (thorn), saw, knife function, in the production process, the use of good quenching high carbon steel, increase strength, wear resistance, corrosion resistance, high temperature resistance. During World War I, the Germans were heavily equipped and used. Now it is fully equipped with our army, and the number of our army is the largest among the three armed forces, and after the collapse of the former Soviet Union, it is also the largest army in the world.

Historically, the People's Liberation Army (PLA) first used shovels in a wide range of military applications in the three major battles, all of which were guerrilla warfare before, and tunnel warfare was not our army and was not considered a large scale. Later, due to historical reasons, China has carried out military strategies such as preparing for war and preparing for famine, digging deep holes and accumulating grain in various parts of the country, and has carried out a large number of underground bunker fortifications.

The birth of a generation of military sapper shovels can be said to be the need for survival, and the soldiers found that the wooden handle of the ordinary shovel was too long, not easy to carry, and easy to expose the target, so the wooden handle was sawed short. Later, this method gradually spread, and the logistics department at that time according to the suggestions of many veterans and field observation of many shovels that have been used for many years, added some small changes to the shovel, first of all, the top end of the wooden handle away from the shovel and the shovel surface parallel to open a small hole, and secondly, according to the wear and tear of some often used old shovels, the wooden handle was changed to a thick-thin-coarse streamlined shape, and small holes were also added on both sides of the shovel surface. The four small holes are designed to use a rope to tie the shovel to the marching bag, which is not easy to fall off during armed swimming, strenuous exercise and long marches, and the streamlined wooden handle is more suitable for hand holding, and traditional army green paint is also used.

When did the second-generation sapper shovel start to be reequipped, to be honest, I don't know very well, but there are already a lot of troop equipment, which can be said to be the mainstream sapper shovel. However, due to the fact that the first generation of shovels has been used for a very long time, and the equipment of our army is usually in sufficient stock, many local troops still commonly use the first generation of shovels. The birth of the second-generation shovel is largely based on the reference to the Soviet army engineer shovel, simply put, it can be folded once, and the handle is changed to a triangular streamlined shape according to the principle of mechanics.

The third generation of shovel is improved to fold twice, the handle is still like a triangular streamline, with shovel, pickaxe, crowbar (thorn), saw, knife function, in the production process, the first generation of shovel uses good steel. The last two generations of shovel technology have not changed much, and they all use good quenched high-carbon steel to increase strength, wear resistance, corrosion resistance, and high temperature resistance. The production process of the real sapper shovel head and pickaxe head has changed the internal molecular structure, which can do the spade surface bending 45 degrees 3000 times and still does not jump, crack, or deform, with super flexibility; ), and the spade head will not be damaged. There are many imitation shovels on the market that can meet one of the standards of toughness and hardness, but they cannot break through the problem of combining the two in one.

This in Li Huan's hand is the third-generation sapper shovel.

Although it is said that the engineer unit digs pits professionally, Li Huan pinched the engineer shovel and felt that he would not lose.

In fact, Li Huan really won't lose, with his aura blessed body, and the huge power brought to him by nanorobots, he can't be compared to an ordinary person. Of course, Company Commander Zhang doesn't think so, Company Commander Zhang feels that he has led the engineering troops to work in the deep mountains and old forests for so long, how can he not lose to a person on a secret front - of course, although Company Commander Zhang feels that he must have won, but he definitely does not mean to look down on Li Huan, he even thinks that this is a fun thing that Li Huan is amusing everyone - he is not to compare, but to find fault with the treat!

As for why, it can only be said that Company Commander Zhang thinks that Li Huan is still quite humane.

After all, everyone came here because of Li Huan - now Company Commander Zhang has confirmed that it is because of the problem with their plane, so the superiors sent them here together, and then everyone accidentally got involved in this parallel world, and now they can't find a way out. They have been drilling in the deep mountains and old forests all their lives, although they have encountered any situation, but this is the first time they have seen such a situation. Although this does not mean that Li Huan killed them - as an engineer, it can only be said that he is carrying out the task of his superiors, although the target of this task is Li Huan, but it must not be confused.

Now Li Huan took the initiative to compete with them, the "engineers", and in the eyes of Company Commander Zhang, Li Huan was actually taking the initiative to propose a disguised compensation. Because in the eyes of Company Commander Zhang, it is true that people on the secret front like Li Huan may be much stronger than him in many places, but when it comes to digging pits...... Company Commander Zhang believes that he has never lost to anyone in his life.

"Then let's do it together?" Company Commander Zhang looked at Li Huan pinching the sapper shovel and gesturing: "Brother Li, wait a minute, you can say it if you can't stand it, you can't flash your waist." If we were in the army in peacetime, we would be able to treat it in time if we flashed our waists. In this wilderness place, there is really no place to treat it. It doesn't matter if we flash our waists, it's okay to stay in bed for a few days, if we have to fly a plane when we get out of here, you really don't get hurt, otherwise no one will fly this plane yet. ”

After Company Commander Zhang finished speaking, a group of small soldiers let out a burst of laughter.

There are even some people who are eager to try: "Company Commander Zhang, don't bully people, I'll apply to help this commander dig together! People are obviously giving us benefits, and if you make peace like this, what benefits do we have! Everyone says that right, if you dig a pit, Company Commander Zhang is too much of a bully, who doesn't know that he is a pacesetter!"

"Yes, yes, I think two people should help together! Company Commander Zhang's performance is still there. I heard that Company Commander Zhang used to be a pacesetter in digging trenches, and one person could dig more than 300 meters in an hour, which was so scary that he caught up with a small excavator. People aren't in engineering, so why are you doing this? ”

After speaking, there were really two small soldiers jumping into the pit, ready to "fight side by side" with Li Huan. Because in their opinion, Li Huan is here to give them benefits. These soldiers have been working in the field for many years in the engineering troops, and if you want to say that the most tired of all the arms, these are probably the only engineering soldiers. The permanent fortifications in the wilderness, the secret strongholds, which were not built by their own hands after exploration, which were not built by hard work in the mountains. But despite this, their treatment is not very high, and now Li Huan wants to propose that everyone should eat a month's meal casually, and the soldiers naturally think that this is Li Huan giving everyone benefits - since it is the chief who wants to give benefits, then the chief can't be allowed to lose too ugly. Company Commander Zhang is a well-known pit digger, and compared with him, the two of them are about the same.

In case this young chief is provoked...... Then can you still have a big meal!

So the two little soldiers naturally felt that they were going to help Li Huan.

"Okay, then you two can help. Company Commander Zhang smiled, and looking at this, Li Huan asked, "Then let's start?"

"You really look down on me!" Li Huan sighed, but he also knew that it was useless to say anything now, and these people didn't feel that they were digging a pit at all, so Li Huan also said more: "Okay, then let's start." ”

How could Li Huan lose? Even if he didn't use aura, just with the power that Xiao Fei blessed him, that shovel would be similar to a small excavator. Company Commander Zhang may really be the business pacesetter of the engineering army, but Li Huan is a "person" outside the world standard. Just when everyone was giggling and watching Li Huan and Company Commander Zhang dig a pit, and were about to watch Li Huan fall behind, the result was less than 30 seconds, and everyone's eyes were straight -- this, is this a person? I'm afraid this is not a person, but a small excavator! Although Company Commander Zhang is also known as a small excavator, but that is because of his excellent skills, everyone gave him the nickname, just kidding, but now look at this young commander who specializes in the secret front, everyone knows that there are really humanoid excavators in this world......

Li Huan went down with the first shovel, and the aura was attached to the shovel, shoveling the soil was like shoveling tofu, and the shovel went down almost directly into the handle! After submerging the handle, Li Huan smiled, exhaled and shouted, "Ha" A soft drink, the two soldiers who came to help were digging hard, and suddenly felt a vibration on the ground, and then they looked back, and their eyes were staring out!

The guy they thought was a guy who couldn't dig a pit on the secret front was holding a shovel and bringing out a piece of soil of at least one cubic meter! The soil was connected to all kinds of vines and underground rhizomes, and when Li Huan dug out that piece of soil, he even tore off the rhizomes attached to it! These soldiers were all professionals from the engineering army, and they could see at a glance that this could not be faked! But what was going on! Just because they were professionals, they could always see more ways than ordinary people. Let's not talk about that piece of soil, the rhizome that is pulled out under the soil has a few meanings! Is this something that people can do!

But don't underestimate these special pits in the field, in professional military terms, this is considered military engineering.

Military engineering is a general term for all kinds of engineering construction used for military purposes and engineering and technical measures taken to support the combat operations of the armed forces. is part of military technology. Engineering construction not only refers to the object of military engineering construction, but also refers to the technical activities such as engineering reconnaissance, survey, design, construction, and maintenance in the whole process of construction, as well as the selection of engineering materials and equipment. The engineering and technical measures to ensure the combat operations of the armed forces include mine-laying, sabotage operations, overcoming obstacles, and crossing, as well as non-construction engineering and technical measures for engineering camouflage and field water supply.

Military engineering is the comprehensive application of civil engineering and many other engineering technologies in the military.

The construction, emergency repair, and maintenance of various military engineering facilities and the engineering and technical measures adopted in combat support require the application of knowledge and technology of many disciplines or specialties, such as the use of engineering geological survey, hydrogeological survey, engineering survey, engineering mechanics, soil mechanics, engineering cybernetics, engineering design, building materials, construction equipment, railway engineering, road engineering, bridge engineering, tunnel and underground engineering, airport engineering, port engineering, water conservancy engineering, special engineering structures, water supply and drainage engineering, river crossing engineering, Theories, techniques, organization and implementation methods of blasting engineering, camouflage engineering, military system engineering, construction machinery and other disciplines or majors, as well as technologies such as electronic computers, mechanical testing, lasers, remote sensing, remote control, and telemetry. Therefore, military engineering is comprehensive in terms of the breadth of the scope of scientific and technological knowledge involved. In addition, along with the development of warfare, especially weaponry, it is necessary to comprehensively use a variety of military engineering projects in order to effectively guarantee the combat operations of the armed forces. Therefore, modern military engineering often organically combines various projects to form a complex for one purpose, and this complex has a tendency to further develop and expand.

Military engineering emerged with the advent of war, and developed with the development of war. Ancient military engineering, relying on manpower and simple manual work to complete, by summing up the successful experience and the lessons of failure in the war, in the process technology and methods of continuous reform and innovation, day by day development and progress. After the 17th century, with the combination of modern mechanics (material mechanics, structural mechanics, fluid mechanics, rock mechanics, rock mechanics, etc.) and civil engineering practice and the development of civil engineering from experience to science, the long-term accumulated practical experience of military engineering has gradually become scientific and theoretical. The long-term development process of military engineering shows that practical engineering experience usually precedes theory and is the source and forerunner of theory; engineering accidents and new situations that arise in the course of construction often reveal new factors that cannot be foreseen, thus triggering people's exploration and research of new engineering theories, and leading to the emergence and development of new theories. In particular, under the conditions of war, many unpredictable situations of the enemy and ourselves and the extremely complicated geographical, terrain, weather, and equipment conditions on the battlefield have a tremendous impact on the construction of military projects and various engineering and technological activities, and the decision-making and handling of many engineering problems need to rely to a great extent on practical experience to adapt to the situation and deal with them decisively. This characteristic of military engineering has been prevalent in all previous wars and will continue to be so. In addition, military engineering is aimed at satisfying the needs of war and meeting tactical requirements. Therefore, some principles and requirements for timeliness, concealment, project quality and engineering construction are different from those of civil engineering. For example, in peacetime, the main emphasis is placed on the quality of the project and the concealment and camouflage; in the construction and emergency repair of the project in wartime, the emphasis is placed on adapting measures to local conditions, using local materials, carrying out work quickly, and completing tasks on time with good quality to ensure the needs of the battle.

Preparing for military engineering on the national territory in peacetime is an important component part of the national defense strategic measures and combat readiness of all sovereign states. In wartime, the results of military engineering preparations can create a good battlefield environment and operational conditions for the army, and are of great significance to winning the initiative in war; in a campaign and battle, the comprehensive use of various military engineering facilities and engineering technical measures can enhance the army's battlefield survivability and speed of maneuver, bring into play the combat effectiveness of weapons and equipment, ensure the safety of command organs, communications facilities, and military supplies, and the smooth flow of transportation, and disrupt and restrict the enemy's mobility, which has a major impact on the course and outcome of a campaign and battle. Therefore, in modern warfare, military engineering has become an important part of the overall combat effectiveness of the composite army.

And it is the engineering troops who carry out these tasks.

The army needs to build roads and bridges on the march, the army needs to dig fortifications for combat, and the army needs to camp in camps, all of which belong to the technical aspects of civil engineering and are to be completed by the army's specialized arms ---- engineering troops. Military engineering has existed since ancient times, and the Great Wall of ancient China is the largest defense project in the world; in addition, there are castles, water villages, trenches, fences, etc. With the development of the times, weapons have improved, the mode of combat has also changed, and the content of military engineering has also expanded. There are positional projects, such as permanent fortifications for border defense and coastal defense; air defense projects under cities; command and communication projects, such as command posts, radar stations, and satellite communication ground stations; military transportation projects, such as national defense highways, military road networks, bridges, ferries, pontoon bridges, oil pipelines, water pipelines, and so on. In addition, there are military ports, airports, weapons test sites, training bases, logistics warehouses, barracks, and shooting range projects. All of the above is constructive work, and military engineering also includes two special tasks: one is blasting, and the other is camouflage. Demolition may be required for the construction of military works, and during combat, the use of blasting to open passages in obstacles and the use of blasting to blow up enemy fortifications, bridges, dams, etc. Both laying mines and clearing mines are the tasks of the engineering troops. Camouflage is a protective measure. In peacetime and wartime, engineering camouflage measures are adopted for the actions of various military installations and armies in order to confuse the enemy so that the enemy's reconnaissance cannot be discovered; sometimes it is necessary to make and arrange some false targets, or even build fake ferries, airports, and buildings, so that it is difficult for the enemy to distinguish between the real and the false, and to mislead the enemy into attacking the false targets, so as to protect the real targets and the real actions of the troops. Due to the continuous development and progress of science and technology, many new technologies and new materials have been applied to the field of military engineering. For example, in the event of natural disasters in peacetime, such as floods, earthquakes, and typhoons, engineering troops are often dispatched to rescue and provide disaster relief. So don't think that the engineering corps is a very unskilled branch of the army, and only knows how to dig pits - this high-level engineering soldier can see the level of Li Huan's shovel at a glance.

That's unheard of......

Everyone is an engineer and knows the difficulty of working in such deep mountains and old forests. If, in some cases, construction machinery cannot be used, purely by hand, then the most painful thing is digging. Because in these deep mountains and old forests, in addition to the soil, in fact, the most painful thing is the root plants that have grown underground for an unknown number of years, and they are connected with each other. The roots of those root plants twisted and twisted into clumps, some of which were clumped together, even harder than cement......

Just a shovel dug it out......

Li Huan looked at everyone's surprised eyes and smiled: "What's the matter, do you think I'm doing a good job as a layman?" How about it, Company Commander Zhang, don't admit defeat, if you admit defeat, your brothers' feast will be gone." I'm a door-to-door benefit, don't give up easily, if you give up now, then you won't have this opportunity in the future. And those two brothers, aren't you here to help, if you want to help, hurry up, just look at what's going on here, don't you think I'm a layman, and I'm not good...... There's only a little bit of left. ”

After speaking, Li Huan went down with a few shovels. If the first shovel shocked everyone, then Li Huan hit it several times in a row, almost faster than digging. Li Huan didn't find the feeling the first time, and it was indeed difficult to dig from the ground. Now that a pit has been dug and there is a suitable angle, Li Huan is almost using the method of cutting tofu to slowly expand the pit - no, not slowly, but incredibly fast, although Li Huan feels that it is still a little slower, he thinks that if he injects spiritual energy into the roots of those vines in the ground and lets them loosen the soil by themselves, then the action can be faster.

With Li Huan's participation, the soil on the ground fell at an alarming speed, and in the end, in fact, no one cared about this competition, even Company Commander Zhang himself didn't look at it, but came over to squat on Li Huan's side, watching Li Huan dig down - he is also an engineering and technical pacesetter, and he has special experience in civil engineering, but he can't see what method Li Huan used to excavate so quickly.

However, Li Huan didn't make Company Commander Zhang too ugly, less than five minutes later, the surrounding soil was cleaned up, Li Huan saw the white bones on the ground, he just smiled slightly: "Company Commander Zhang, everyone, in fact, whoever digs it out first, I will invite you to a month's dinner, just to amuse everyone." You must be wondering why I can dig so fast, right? Actually, I won't hide it from you, I'm a so-called person with special abilities, and you can imagine me as someone with special skills in some way...... As for why I'm digging so fast, it's because I have some power that you can't understand. But to be honest, Company Commander Zhang, you are the fastest civil engineer among all the people I have seen. ”

"That's ...... So that's the case!" Company Commander Zhang was stunned for a moment, and then suddenly realized: "No wonder my old Zhang can't see why you can dig so fast! So that's the case! No wonder we came here to build an airport for you to land! Okay, I understand, this is all me Meng Lang, you don't have to do the rest of Brother Li, I'll let the brothers clean up, slow work and careful work, there are still a lot of people!"

Li Huan's explanation, everyone understands, because after the Mexican rainforest incident, the existence of people with special abilities has actually begun to acquiesce in the armies of countries around the world. And China has always been at the forefront of the world in this regard. Naturally, the engineering troops have also popularized the relevant knowledge. So as soon as Li Huan said this, Company Commander Zhang understood. And he is quite grateful to Li Huan for taking the initiative to tell this matter - otherwise, he would be a dignified engineering company commander, and he would put his face in such a place in the future!

Company Commander Zhang's words about slow work and meticulous work are also right, after Li Huan took a big step to clean up the soil covering it, the rest was for the soldiers to clean it up slowly. However, it may be influenced by Li Huan, and this is slowly not accurate - everyone is like being beaten with chicken blood, everyone's movements are fast, and in less than twenty minutes, Xiao Song, who was filming the bones with his mobile phone, has already come to report: "Company commander, we have cleaned up the bones!"

"Brother Li, the bones have been cleaned out, let's go and have a look?" Company Commander Zhang took the lead and jumped down the pit: "If this ghost thing asked us to come to this ghost place, you will definitely be able to find a clue, right?" ”

"I'm just guessing that, not necessarily saying that we can find clues, but if it's really it's the fault, we'll always have a way to solve it. Li Huan said.
