For the bows and crossbows of later generations, one is to wind with feet, and the other can be wound with threads, and for Xiao Niang, these two are not suitable for her, her strength is too small, Yang Heng does not have to make a bow and crossbow for Xiao Niang, but think about it carefully, this may be a test test, if you use a bed crossbow, it is also possible, according to legend, bed crossbows are wound with the strength of a person's whole body, but if you use afterburner, will the power of this bed crossbow be greater, naturally, this is not what Yang Heng needs to study, As long as a small bow and crossbow is made for Xiao Niang, then Li Er will naturally associate it with the bed crossbow.

This crossbow, Yang Heng is the use of the later generations of the butt-type firing method, even the three-point one-line sight, naturally not the kind of telescopic sight, but the sight of an ordinary firearm, on the butt fixed to the crossbow body, the crossbow string is driven by a zigzag mechanism, there is also a lever with 20 times the force, only need to pull less than ten times, you can put the string on, and then put the pruning in the arrow groove, after aiming, a pull of the trigger, the pruning can be launched out, naturally, There are also a number of anti-misfire devices on it, and the shooter can only pull the trigger when he is holding his shoulder against the butt.

Even, Yang Heng also designed a two-legged bracket separately, and when he put the crossbow on the bracket when shooting, it can be easily operated. As for Yang Heng, he must now have a middleman, that is, Xiao Niang, to make some willful requirements, and then he will make one object after another, so that it will not be abrupt, if Yang Heng wants to play with a bow and crossbow, it will be too unusual, his strength is greater than his father, what kind of bow and crossbow to use. Therefore, for a period of time, this little lady played the role of a catalyst.

This bow is also available, and the crossbow is also available, but Yang Heng found that the pruning is not very assured, the lethality of the pruning is too small, so Yang Heng decided to make a special arrow, he plans to make the arrow by turning the sand, and then after grinding it on the grinder, it becomes a suitable arrow, and then stuffs the arrow shaft in, this is a suitable arrow, the arrow shaft, and the wings are not easy to change, and even the crossbow used by the little lady does not need wings, because the crossbow uses the technique of the guide rail, so, The role of wings has been greatly reduced.

How is the grinding wheel made, this needs to find some sandstone back, and then divide the thickness, and then after building, make the shape of a round wheel, and then make a fixed hole in the middle, and then add it to the waterwheel axle, this is a grinder.

Even Yang Heng went to the market alone to buy some middle-aged men in order to find the people to operate this waterwheel, and people of this age don't have too many ideas, so they can teach them some simple techniques at will, and naturally someone still has to watch them to prevent some unnecessary things from happening.

"Boy, this is the iron bow you made, why is it so ugly." Dad actually thought at first glance that this iron tire bow was a little ugly, this was the bow body that Yang Heng carefully polished, and even used passivation, he didn't want Dad to let the other party avoid it when shooting arrows, the shape of this bow body is the style of the composite bow, the bowstring is hung with it, otherwise it is easy to break the bowstring, and the elasticity of the bow body is reduced, which is determined by some special properties of steel.

Looking at the arrow again, it is also dark, but its tip is very sharp, and it even has three blade ridges, even if it is shot on some iron plates, it will also shoot through this iron plate, but if you want to ask Yang Heng's pruning to shoot the armor he made, there is no comment, you can try it yourself.

"One hundred steps." A tree with the thickness of the mouth of the bowl was shot through, one hundred and fifty paces, again, it was shot through, two hundred steps, this time it was not shot through, but it was also deeply rooted in the trunk.

"Brother Heng, look at me, look at me, come here, put up the shelf for me." The little lady is very nervous, now she has weapons, and even has a special attendant, who carries a bow and crossbow for her and a shelf.

"Little lady, the crossbow is ready, and there is no one in the distance, you can shoot." This is Yang Heng's rule, maybe the little lady will not pay attention to things in the distance, but with her followers, then you must observe the surrounding situation, otherwise you can't shoot, don't hurt people for no reason.

"Come, Arrow." Similarly, the arrows are also in charge of the attendants, which is also for safety reasons, and who knows when this little child will be hot-headed.

"Click." Xiao Niang on the string, the unique sound of the power lever is quite pleasant, finally after a dozen times, Xiao Niang put the string on, and then put a featherless arrow into the arrow slot, she also seriously aimed at the accurate, "snap" a bowstring sound, the arrow shot out of the trunk like a bolt of lightning, Peng, this arrow was above the first arrow shot by the father from the trunk out of the trunk.

"One more arrow." "Click," the little lady continued to wind, and the second "Peng" shot out from the top of the place where the second arrow was located.

"The third." It seems that Yang Heng's calculation is good, this bow and crossbow is not much worse than Dad's bow.

"Boy, you made it, it's amazing that a child can control it." Although it was amazing, the father didn't think too much, he couldn't take a child to the battlefield, and he wouldn't associate this matter with other places.

When the bow and arrows were made, Daddy put them on the shelf, even the armor, and the spear, which Daddy meant that if he didn't participate in the war, he wouldn't use them, and naturally, these things were just a flash in the pan and didn't attract anyone's attention.

And Xiao Niang is not like this, she practices shooting in a courtyard every day, even when she comes back from school, she can't forget to practice a few times, and Yang Heng has no choice, every time he has to guard her, in case of any accidents, while guarding, he also has to teach a maid who follows Xiao Niang.

"Squire sword, let me tell you, you must pay attention to this pruning, the little lady has used one, and give her another one, and also, before setting up the bow and crossbow, you must observe the surrounding environment, so as to prevent someone from suddenly coming out of the place where you don't know the way, even if there is no one, you must also let the people around you pay attention, and don't let people come in recklessly." "Yes, follow Xiao Langjun's orders." The sword loves you, naturally it is the name given by the little lady, and with her back bow and arrow, naturally she will not give any flowers and grass, so it will be called the sword, and slowly become the sword.
