The height of this mecha is only about 1.8 meters, which is a little shorter than me. The observation scope cover on its head is one point shorter than the arc cover of an ordinary mecha, and the height of its entire waist is about ten centimeters shorter than that of me, a 1.9-meter person, and the whole is a bantam tiger with long body and short legs.

Its right arm is very complete, and it does not have only a six-barreled machine gun like before, nor does it have a laser gun like a normal three-machine gun. On the left shoulder, there is a shiny laser device, and the laser gun is still installed after considering all factors. Its two hands were empty, and from a weapon's point of view, those arms were of little use, unless they contained something inside. The six-barreled machine gun, which was installed last time, was canceled and disappeared. Could it be that the weapon is still returning to the light weapon, impossible! Of course, the mech's death shield should be put to good use.

"You canceled the machine gun? How can a laser gun be put on the shoulder, isn't it nice to press it on the arm? Looking at this mecha that seemed to have returned to the ordinary three-machine design, I glanced at Yun Hao with suspicion, "Also, is the ratio of this body and legs changed!" It's so incongruous, and it looks weird. ”

"Do you think the proportions of the body and legs make the whole mech a little ugly?"

"yes!" I'm depressed, everyone loves beauty, and if this mech is walking outside now, I guess it's no problem to make headlines.

"Also, are these empty hands of any use? You don't want him to make things, do you? ”

"Hah! Ha! Ha! Yun Hao laughed, "You're half right, the free hands naturally have their use, he is used to hold a gun." ”

Yun Hao watched me pretend to shake his head mysteriously slightly, and he was very complacent. He then walked up to the mech, and his fingers quickly operated on the mech, and in a short time the whole mech was fully activated. I saw that the three-eyed observation mirror on the top of its head kept rotating slightly from side to side, and finally turned to Yun Hao's side, and made an extremely humane voice: "Maker, the serval is ready, ask for instructions." ”

"Grab your gun and get ready to fight." Yun Hao calmly gave the order.

The mecha (let's call it the "Serval" for now) turned around and quickly walked to a corner and pulled out a handful of hot . An assault rifle that looks like the age of weapons. It holds the barrel in its left hand and holds the grip in its right hand, and the butt is naturally bent over the shoulders and legs. The firing stance of the Age of Weapons finally made the following sound: "The serval is ready, and no enemy has been found." ”

I was completely stunned, it completely upended my perception of mechs in general, which are always mechanical and rigid when fighting. All mechs' combat moves, including walking, are procedurally identical, and some joke that mechs only have two movements, forward and shooting. And Yun Hao's mecha is obviously very anthropomorphic and very special.

Looking at me in a daze, Yun Hao walked in front of me and said, "I don't want to make just a killing weapon, I want to make a mecha that has at least general common sense, it should have general judgment ability, and have a certain learning ability." ”

"Don't take a detour, intelligent armed mechs are strictly forbidden by the Alliance." I can't help but be a little nervous, you must know that there have been accidents in the history of intelligent robots, and now the intelligence of robots in the alliance is strictly based on the hierarchy

Intelligent robots are used more in some scientific research fields, and the convenience of combat robots is strictly prohibited.

"You don't have to worry too much, I naturally know this rule, so I played a sideline to mainly strengthen the learning of combat skills and set some basic common sense. If you encounter a mecha attack in peaceful mode, you can freely return fire even if you don't have a command, but the original alliance stipulates that even if a mecha is attacked, it will not fire back even if it is not in battle mode. Now the alliance may be entering an eventful time, and I have heard that the alliance has relaxed on this aspect. Of course, the only object of free return fire is mechs. ”

"Is that so?" I still looked at Yun Hao with a little suspicion, and Yun Hao nodded firmly.

"So what's the condition of this gun if it's hot. In the age of weapons, you can set up a magazine with 30 rounds! The firepower is too weak, and the sustained combat is too poor. "I pointed to the seemingly well-made assault rifle, I remember that the last time Yun Hao introduced it, he said that it basically takes about 20 rounds to cause some damage to a mech, and it takes time to change the magazine, so this 30-round loading assault rifle is equivalent to becoming a single-shot rifle.

"Huh! Scold! I knew you would say that. Yun Hao glanced at me, smiled and said, "You go and see how many bullets are loaded in this magazine." ”

I was a little curious and looked at this and hot. I thought to myself about the similarly sized magazine in the era of weapons, how many can I hold? Even if the caliber of ammunition is reduced, it will be about the same as a 50-round load.

I walked up to the serval and was about to take the gun over and remove the magazine (a normal mecha is a way for humans to refuse if they want to do something that doesn't damage it). The serval unloaded the magazine and handed it to me. I looked at Yun Hao again in a daze.

"Don't be surprised, although I didn't give orders, it understood us, and it didn't mechanically execute orders, which is also an area of improvement for me." Yun Hao obviously understood what I meant and explained. (Robots don't have commands and generally don't take the initiative to do anything).

I took the magazine and looked at it, but my right hand sank involuntarily and almost didn't hold it. I hurriedly grabbed it, but when I looked closer, I was startled. What kind of magazine is this! First of all, its weight is much heavier than I expected, estimated to be about twenty pounds, and the normal 30-round magazine like this is only two or three pounds! In addition, this kind of ammunition has no shell, it is a caseless bullet, and a small shiny tail of more than one centimeter is tightly attached to the warhead. Ejaculation. The diameter of the warhead is also relatively small, the diameter should be only about 6mm. The projectile is also very short, and the whole warhead is haired. The length of the shot is only about 5 centimeters.

What is even more strange is that the entire magazine cross-section is divided into four rectangular squares by a cross, and the upper left and lower right squares expose the ammunition, which is actually arranged tail to tail. The lower left and upper right compartments are blocked by a lid so that you can't see the ammo inside, but by size it can accommodate the same amount of ammo as the exposed compartment.

"Why is it so heavy!" My brow was tightly locked, and I turned the magazine in my hand to look at it, and finally my brow was slightly relieved, and I saw a little Mingtang. It turned out that the width of the entire magazine was enough to accommodate four columns of ammunition side by side, but the four columns of ammunition feeding would cause ammunition supply failures, so Yun Hao made a vertical plate division along the longitudinal direction of this magazine

Due to the interface problem, the left and right ammunition are in opposite directions, so that when the ammunition on one side is finished, you can continue firing as long as you quickly remove the magazine and put it on, which must be said to be a good idea.

"There should also be ammunition under the two covered compartments, how to load them if they are covered!" I tossed the magazine over, admiring my friend's design, but I still couldn't figure out how the covered lattice was fed. Looking at Yun Hao's idea should be to design the entire magazine into a flat loading arrangement with two front and rear four columns side by side with a total of eight rounds, but I have figured out the four-row parallel ammunition feeding method, and the front and rear two columns have not figured out the ammunition feeding method, so I can only ask the designer himself.

Yun Hao took it, and pressed it there, and the two covered lattices also revealed their true faces, and sure enough, they were filled with the same ammunition as I thought. Yun Hao frowned slightly, threw the magazine in his hand up and played, and a slightly smug voice sounded.

"I spent a lot of time for the design of this whole clip, the whole magazine is arranged in two rows and four columns, and the two rows and two columns on the left side are finished after taking off the magazine and reloading it to continue firing the ammunition on the right, so the direction of the ammunition loading on the left and right is reversed." I nodded, something I had just thought of.

Yun Hao's loud voice continued to sound: "As for the front and rear rows of ammunition, I designed a device in the magazine, after loading the bomb cover plate, as long as the ammunition in the front row finishes firing the rear row, it will be automatically pushed to the front row, and after my test, the ammunition supply is good, and there is no ammunition supply failure." ”

"That's it! Yes, yes, to be able to hold so much ammunition in such a small magazine, the continuous firing of firepower is guaranteed. But can the power of such a small-caliber ammunition be guaranteed? Also, how could this bullet weigh so much, the hair. What kind of material is used for ejaculation, it is very beautiful to shine. "I asked all the questions in one go, and sometimes it was really uncomfortable to hold the questions in my heart.

Yun Hao's smile became even happier, and his eyes became a line of laughter. "You're getting to the point, I have a magazine that can hold a total of 200 rounds, and these designs are based on the following factors: a small warhead of sufficient weight and a suitable force. Ejaculate, hair. I use metallic hydrogen for the projection, and the small warhead with enough weight you guess, in fact, you usually come into contact with it. ”

"Fat. Metallic hydrogen for ejection, warhead is a material that I often come into contact with! ”

I'm a little confused, metal hydrogen is a relatively commonly used solid energetic material, and the use of caseless bullet design can greatly reduce recoil, you must know that an important reason for the elimination of gunpowder weapons is to maintain the power must find a suitable energetic material, and the energetic power potential of gunpowder materials is basically developed to be exhausted. Another point is that as the power increases, the recoil of the bullet is too large for humans to bear, and modern human genes have improved their strength and other physical qualities, and it is possible to withstand such a large amount of recoil. And the recoil itself of ammunition of such a small caliber will be much smaller. And there are still materials with large weight and small volume, is it ......"

After thinking about it for a long time, I finally had an answer, looked directly into Yun Hao's eyes and said, "You won't use Q steel to make a warhead, right?" ”
