Capital, Army General Hospital.

In the white room, there was a smell of disinfectant everywhere, and on the clean and tidy hospital bed, a young man lay on it, silently looking at the liquid that was dripping and falling from the infusion set, not knowing what he was thinking.

Crunch...... The door opened, and a straight figure appeared in the doorway, he looked at the legs of the young man covered by the quilt on the hospital bed, and a sad expression appeared on his face, he tried to control his mood, and barely squeezed out a smile.

"Company Commander Hu, why are you here?" The young man on the hospital bed saw Hu Tianming and immediately asked curiously, "Aren't you going to the Army Command Academy for further study?" ”

"Well, I'm not in a hurry to leave." Hu Tianming said: "The things in the capital haven't been done yet, so I just came over to see you today, Liangzi, how do you feel?" ”

While speaking, Hu Tianming had already walked to the front, put the net pocket he brought on the bedside table, took out a canned orange from it, then took out the saber he was carrying, cut the lid out of a cross shape, swing it open, and then held it with his left hand and took the spoon with his right hand.

Seeing that Hu Tianming was going to feed himself, He Liang was immediately annoyed: "Company Commander Hu, are you looking down on people?" I'm just a cripple with no legs, my arms are still good, and I can still eat. ”

"Don't you still have an infusion needle in your hand, it's inconvenient."

"I still have a hand." After He Liang finished speaking, he exposed his other hand: "At that time, my leg was blown off, and I used this pair of hands, holding a sapper shovel, to open the monkey's head......"

After He Liang finished speaking, he picked up his quilt nonchalantly, there was nothing below his thighs, and he had a smile on his face: "I just don't have legs, the monkey has no head, or I earned it." ”

Hu Tianming looked at He Liang's thighs, tears were rolling in his eyes, a good comrade-in-arms of the company, born and died on the battlefield together, and came back together to accept the commendation of the superior leaders, but he was unscathed, but this comrade-in-arms lost his legs.

"Hey, Company Commander Hu, if you cry your nose, get out, let's be soldiers, blood, sweat and tears."

"Well, no, it's just sand in my eyes." Hu Tianming tried hard to control his emotions, and then said, "Liangzi, what are your plans next?" ”

"I don't have any plans, when the injury is healed, I will retire and go back, I can't stay in the army like this, even if the superior leader said that I can be arranged to do a civilian job, but I have just become Chinese, and I have already returned it to the teacher, and I went to the government unit, just a cup of tea and a newspaper for a day, that is not a waste of national resources." He Liang said: "I want to go home and farm the land without causing trouble to the country." ”

Hu Tianming was silent for a while, and then spoke: "Is there anyone else in your family?" ”

"I have two older brothers, and I have a younger sister below, and my sister is in college in the capital...... However, I can't let her know about me now, and I'll talk about it when I get home. ”

Hu Tianming was silent again.

"By the way, I heard that you went back to the old army and organized a discharge ceremony there, and then, the people there sang you a nice song? Lian Commander Hu, sing for me? I'm suffocating here. ”

The soldiers on the two beds next to him also sat up and pricked up their ears.

"My old squad leader, how are you doing now...... Hu Tianming sang, this kind of song is catchy, you can hum it after listening to it, although it may be out of tune.

In the hospital room, voices kept coming out.

"Has your hometown changed over the years, has your wish come true over the years, has you also left your home, have you gone to the south, and created a new ideal ......?"

Hearing this, He Liang's eyes were shining, ideals, what are his ideals? I will be a soldier for a lifetime, but I won't even be able to stand up in the future!

"Have you married all these years, squad leader, and what does sister-in-law look like?"

When he heard this, He Liang thought of something again, at the beginning, Company Commander Hu saved the nurse, it is said that the nurse has been very close to Company Commander Hu, that nurse, will it be the sister-in-law in the future?

When Hu Tianming finished singing, he found that he didn't know when, and the soldiers from other wards had also gathered at the door, all watching him at the door.

"Lian Commander Hu, this song is so good!"

"Yes, Lian Commander Hu, can you teach us this song? When I get better, sing it to my old squad leader. ”

"Lian Commander Hu, who made this song?"

Hearing this, Hu Tianming's tone was complicated: "Mr. Qin." ”

Mr. Qin is simply an all-rounder, he can do anything! What is Mr. Qin doing now?

Qin Feng was in the 201 Institute, discussing with a group of people.

"Mr. Qin, we have completed the imitation of the contact-1 explosive reactive armor, but we always feel that there is still something missing."

"Yes, this kind of explosive reactive armor cannot be fully rolled out, there is a gap between each other, and if the armor-piercing shell hits along this gap, it will lose its protection."

"Well, this kind of explosive reactive armor is used to modify our old tanks, such as the old 59, which is the most suitable, but if it is to be placed on our new third-generation tank, it is still a little worse, our technicians must continue to develop new explosive reactive armor, solve the problem of serial guns, and let this explosive reactive armor be arranged next to each other, which is better."

In later generations, at the beginning of the third generation of domestic tanks, there was a V-shaped wave shield in front, the same as the T-72's, but it was flat in the later stage, because additional explosive reactive armor was added to it, but this layer of armor did not see bricks one by one, but closely arranged, of course, because the problem of martyrdom has been solved, and it can be done together.

The principle of explosive reactive armor is very simple, that is, when the armor-piercing and armor-piercing shells come over, they will explode on their own, thereby reducing the attack power of the projectile, but what is this trigger point?

It's too light, otherwise the machine gun bullets will blow up this kind of thing, so what's the use? It's not okay if it's too heavy, otherwise the armor-piercing shell won't explode, so what's the point, the principle of explosive reactive armor has long been there, but if you want to make it, you need a special blunt explosive, which is the heart and soul of the entire armor.

Even so, explosive reactive armor is not perfect, when one of them explodes, you have to prevent it from affecting the nearby armor, otherwise, it is the same as setting off firecrackers, after one piece explodes, the others will also explode, so what's the point.

Now, in order to avoid a chain reaction, it can only be used at separate distances, so the gaps between the brick blocks are not for ease of installation, but for not to hurt the innocent.

How to solve this? Qin Feng didn't know, after all, this was the secret of the military industry, only the R&D personnel knew about it, he only knew that he could do it, and that was enough.

"This contact-1 explosive reactive armor is only resistant to armor-piercing shells, not armor-piercing shells."

"We can do this by improving the design, for example, by stacking three Contact-1s on top of each other to form a new explosive reactive armor, and moving the throwing plate and the backplate to each other to cut the ......."

The technical things are endless, and before you know it, it's getting dark outside.

"Well, guys, can you let me go? Originally, there were still very important things today......" Qin Feng looked at the people present.

"Mr. Qin, what did you originally do? And can it be compared to our tank technology? Li Runzhu asked beside him, he is a busy man, and he is also involved, participating in test firing together, and holding meetings to discuss together, what can Qin Feng do, more important than his own affairs?

Qin Feng was suddenly embarrassed, I said casually, are you still serious? However, after thinking about it, an idea came out of my mind again: "I originally planned to go back to the university to have a look, there are two projects invested and developed by our Pacific Group, which also have a lot to do with the army." ”

"Really? Then I'm going to check it out. ”

Next to Li Runzhu, the assistant whispered: "Leader Li, you still have an hour, and it's time to leave for the south." ”

"Don't worry, isn't there still an hour, I'll go and take a look with Mr. Qin." Li Runzhu said: "I'll see what advanced things are being researched in their university. Let's go, Mr. Qin, let's go now and drive that warrior car! ”

Li Runzhu looked full of interest.

"Leader Li, the warrior car is a little too ostentatious, let's change to a more low-key one."

"Okay."

Half an hour later, Capital University, Faculty of Engineering.

In the small brick-red building, a person walked out of the laboratory, and there were several shiny skeleton-like things on the outside of her legs, extending all the way to her back, forming a whole, and at this time, on the back, you can see a backpack platform made of skeletons, which is stuffed with pieces of ...... Slab bricks!

There are five pieces in one layer, a total of four layers, which is twenty pieces, and one piece of five catties is one hundred catties, which is fifty kilograms!

For a man who does manual work, this weight is not a big deal, after all, he carries the burden of the whole family on his shoulders, not to mention fifty kilograms, and one hundred kilograms can be carried, but now this is a girl!

She weighed fifty kilograms, but as if she didn't have much effort, she walked forward with her legs open as if she were walking.

Although the back is heavy, there is also material in the front, so you can maintain your balance and not fall.

"Senior sister, be careful!" A somewhat anxious voice sounded from behind: "This human exoskeleton is the first version, it must be defective, you have to test it, let me test it first." ”

He Xiao turned his head and looked at Zhang Shengwang: "Senior brother, you are engaged in quadruped robots, and I am engaged in human exoskeletons, of course I have to test it myself." I had to experience it myself to know what the pros and cons were. ”

After He Xiao finished speaking, he turned his head and smiled, and then looked at the stairs in front of him: "Now, I want to climb up to the fourth floor, and then come down again, simulating weight-bearing climbing." ”

"Okay, then you slow down."

If it was usual, He Xiao would definitely not be so strong, it was okay to go upstairs with a few books, and go upstairs with bricks on his back, but he really didn't have this level.

She stepped out of her left leg and began to ascend the first step, and when her right leg was raised, the elastic mechanism released the energy that had just been stored, and the left leg did not exert much force, and her body followed the bracket!

Her right foot also fell to the first step, and then she stepped her right foot to the second step, waited until her right foot landed, and then used the elastic mechanism on her right to exert force to bring her body up, step by step, step by step, it was so easy!

One level, one level, and soon, halfway up the steps.

At this moment, a surprised voice came from behind.

"Mr. Qin, this is your project? A girl with a hundred-pound brick on her back and easily climbs the stairs? That's amazing! ”

"Well, there are still many problems in the front-line use, but if it is only provided to logistics personnel, it can still save a lot of physical strength for logistics personnel, and it can also be easy to replenish supplies to various mountains." Another voice rang out.

He Xiao was very excited, turned his head back, and looked at the door. Sure enough, Mr. Qin and another person appeared there, and that person looked like a leader.

She wanted to stop, but her legs had already adapted to the rhythm of the steps, the exoskeleton continued to exert force, and her body involuntarily walked upward, so that her body suddenly could not maintain balance.

"Ah......h

It's so dangerous, if the bones come down, even if you don't break the bones, you have to fall with a blue nose and swollen face! Zhang Shengwang's heart was full of fear, wait, it seems that the position of the hand push is very soft? He fixed his eyes and saw that his hand was touching the two round white rabbits!

Zhang Shengwang hurriedly retracted his hand, but He Xiao didn't care, the two of them were going to get married sooner or later, and sooner or later they were going to be together, but unfortunately Zhang Shengwang didn't mean it, this person, his mind is full of scientific research, when can he have a normal man's thoughts?

"That, senior sister, you guys come down first, it's too dangerous." Qin Feng spoke.

"Okay." He Xiao adjusted his mood, took two deep breaths, and then slowly walked down, step by step, steadily.

It's easy to go up the mountain and difficult to go down, and it's even more difficult to go down the mountain with things on your back, now, seeing He Xiao walking down step by step, Li Runzhu's eyes widened, this thing must be equipped to the front-line troops! Warriors can save a lot of stamina!

Mr. Qin is amazing, he can always get some strange things, and he is very easy to use.

"What is this?"

"Human exoskeleton."

"I remember, you showed the human exoskeleton at the German Security Exhibition, isn't that the case."

"That's the final form." Qin Feng said: "Now this is just a simple version, it belongs to a non-powered exoskeleton, but after this exoskeleton is developed and matured, it can still be used in many places, Leader Li, this still needs to be improved, do you want it now?" ”

"Well, the sooner the better, let's go inside."

Faculty of Engineering, next to the Radio Association.

In the university, students like to organize all kinds of associations, the Faculty of Engineering is engaged in engineering, and the Radio Association can give full play to the flexible hands of students, so it was established very early and occupied a special classroom, and after the university decided to support the research and development project of the Pacific Group, the next classroom was vacated and transformed into a laboratory for human exoskeletons and quadruped robots, so that the two sides can also facilitate mutual cooperation.

When Li Runzhu walked in, he saw six personal computers in the corner, with a white appearance, a horizontal chassis, a large CRT monitor squatting on it, with cursors and letters flashing in it, and a keyboard in front of the case, no mouse.

In front of every computer, there are people who are busy, and there is a big table as a working platform on the side, and some people are busy. Although there are not many of them, they are all elites.

"Computer?" Li Runzhu's eyes widened: "This is what the university is allotting?" ”

"Of course, it was purchased by Mr. Qin." Zhang Shengwang said: "This is still the most advanced 386 computer, more than 50,000 yuan a piece, where is the school willing to equip us with so many units." ”

Personal computers have been available since the early eighties, and of course the Capital University also has a special computer room, and a few years ago, a batch of 286 computers were purchased, which is already full of praise, and you have to wear shoe covers when entering and exiting the computer room, so it is difficult to queue up.

Now, they need computers for this project, and Mr. Qin bought six of them, which are still the most advanced 386 computers, I don't know how many people envy them.

"Do you need a computer for your project?"

"Yes." Zhang Shengwang nodded: "Our quadruped robot project completely relies on computer systems and needs to write complex programs, as for the human exoskeleton, even if it is unpowered, it needs to be controlled by a computer." ”

He Xiao freed the exoskeleton system, and there was a box in the position on his back, and inside was a single-chip microcomputer, the required program was not very complicated, and an 8-bit 51 single-chip microcomputer could handle it.

He Xiao took out the serial port data link, connected it to this box, and began to read the data just tested.

If you want to make the project mature, you have to keep testing, keep accumulating data, and constantly improve the program, which is a long process, but He Xiao has this confidence.

Li Runzhu watched it for a while and found that he couldn't understand it, so he could only go to see Zhang Shengwang again.

Zhang Shengwang had already come to the big platform, watching the others busy with their work, Li Runzhu looked over curiously and saw a monster with four mechanical legs.

"What is this?"

"Quadruped robot, now we'll call it a mechanical dog." Zhang Shengwang introduced: "The size is about the same as a dog, we want it to be able to walk, run, jump, and somersault." The controls are extremely complex, so, inside it, we put in a 386 processor. ”

"What's the use of that?"

"It's certainly not very useful to be so big, but as long as the program is debugged, we can make a bigger one in the future, such as the size of a cow, and carry supplies in the mountains."

Mechanical cows? Mountain area? Li Runzhu's eyes widened suddenly: "Our plateau outpost needs this kind of machine to supply supplies, Mr. Qin, you are right, the meaning of these things is really more important than me going to the south!" ”

To the south?

Looking at Li Runzhu's temperament, He Xiao spoke: "This leader, you came back from the south?" Do you know my brother? He was also on the south side. ”

"What's your brother's name?"

"He Liang."

Li Runzhu's assistant on the side was in a hurry, Leader Li, we will soon not be able to catch the southbound plane, what are you still rubbing here! An ordinary warrior, you don't know.

"There is a combat hero named He Liang, he was wounded on the battlefield and is currently ...... in the Army General Hospital" Li Runzhu really knows this name, but he doesn't know if it is the brother of the girl in front of him.

However, before the words were finished, He Xiao had already run out.
