"Ordinary Qin crossbows use featherless arrows, in order to make the crossbow arrows fly farther. However, in this way, there is no guarantee of accuracy. Although it can shoot 500 steps, experiments have proved that there is not much lethality at 500 steps. It can only shoot through sackcloth clothes, and the best killing distance is about 200 to 250 paces. At this distance, the leather armor of the Huns could be easily torn apart even if it was anointed. Even if you encounter Wei Wushu's bronze heavy armor, you can shoot through it, but the power will be reduced a lot. Our bow with an eccentric chakra seems to be able to do this kind of power. However, the bow's arrows have tail feathers, which is much more accurate.

This is a bow with a turntable crank with a bow arm made of thin sheet steel. The bowstring is drawn out of steel wire using the latest drawing process. Crossbow arrows with tail feathers can be sent out for 800 paces, and the effective killing distance is 400 paces. The power can penetrate the heavy armor, and it is a matchless weapon on the battlefield. ”

The Rooster Crown Mountain Weapons Test Site is already a military city. Several small castles form a strong fortress, and it can be seen that there must have been a strong fang to guide the site when choosing a location. The castles supported each other, forming a strong defensive group. The castle is home to all sorts of brain-splitting killing machines, with rows of pointed iron spears. There is also a pumpkin-sized steel ball covered with thorns, which are said to have been chained during the war. will swing back and forth like a pendulum, thinking about the person who climbs the ladder, Yun Yue feels cold in the bottom of her heart.

There is also a kind of clay pot with Western Regions fire oil sealed and thrown into the city when it is lit in wartime. This thing is definitely a nightmare for the siege soldiers, I heard that Master Geng also distilled and purified, and the result of the experiment was to add some frosting, which would be more powerful. This thing is starting to play distillation. Yun Yue admired the spirit of exploration of the ancients.

The most impressive thing is the improved three-bow bed crossbow. Although the volume has been reduced a bit. But the range and power have increased dramatically. The function of the winch is used to make winding easier. It only takes three people to complete the operation, which can be described as the only force for home travel to kill people and goods.

What Master Geng is showing off is a two-point zero version of the three-bow bed crossbow. The size is even smaller, and the whole crossbow is handmade. The bolts with tail feathers were two feet long, and the shaft was as thick as a thumb. A crossbow bolt can't fly far without a little weight, and the sound of the launch is actually a bit like the sound of tearing linen.

The villain four hundred steps away was wearing a flat cool heavy armor, and the heavy armor made of pure steel was actually torn apart like a piece of paper. The tail feathers are nailed to the heavy armor, and the barbs on the shaft of the arrow can be clearly seen crooked.

"This wolf-tooth arrow went in. It's going to be hard to think about. The wound will more than double in size, and if it hits a vital part, it can kill a person by bleeding alone. Master Geng was very proud, Yun Yue looked at the Mercedes-Benz mark on the heavy armor and agreed with his statement. The spear stab of the Type 56 semi-automatic rifle in later generations has this function.

Yun Yue took this new type of crossbow arrow, and the range was really fucking heavy. I'm afraid that it won't be less than fifteen or sixteen catties, and this thing will definitely not be used by cavalry and infantry. It's so fucking heavy!

"There's no way this crossbow is too powerful, why explain that it's all steel, it's all pure steel, and it will naturally be heavier. But it's good for the soldiers. You see there's a groove here. It is specially hung on the carriage board, so the weight will be reduced a lot. Master Geng turned the crossbow over. Show Yun Yue a small pendant under the crossbow.

"It's true that this thing can only be used by chariots, how many have you built?" The big war is coming, and Yun Yue likes this kind of thing very much.

"Mass manufacturing has begun, it's just that it's too labor-intensive. The existing parts are assembled to almost 100 units. The main reason is that the process of steel wire is immature and the output is too low. ”

"Craftsmanship is something that can be improved slowly, and a lot of things have been developed over many generations. We've advanced a lot, don't spread the manufacturing method of this thing, and don't go to the battlefield until you restrain this thing. ”

"Hahaha! Hou Ye is too worried, you look at the things over there. Yun Yue turned her head and saw a huge wooden shelf. Oh my God, this guy made a trebuchet so big. How does this thing move?

"This kind of large trebuchet can shoot up to 1,000 steps. Each boulder has a hundred and ten catties, and this small iron-armed crossbow is nothing. Master Geng's face was full of smugness, and he looked very satisfied with this thing.

"It's a good thing, it's powerful, and it's long-range. But how do I get this thing down the city? You can't pull this thing away with a hundred cows......! ”

"Uh......!" Master Geng's face turned red, and he ignored the volume in pursuit of power. It's a little too big.

Yun Yue came to inspect Cockscomb Mountain this time to see what these people had turned Cockscomb Mountain into. Now it seems that it has become a strong fortress. I don't know how many bones of the Qiang and Yue people were buried under these stone walls. It is estimated that there will be no fewer people than Qin Shi Huang who died when he repaired the Great Wall, and Zhang Han desperately caught strong men in the Western Regions. But Li Si always complained about the lack of manpower, and now the whole rich Hetao grassland. Except for a few relatively large Xiongnu tribes, other small tribes have disappeared without a trace. I'm afraid they were all caught and filled in this cockscomb mountain.

"Master Hou, there is a coal mine in front of you. Next to it is a charcoal cave, from which the kind of coke you mentioned is burned. "Chu Dayong prides himself on being the head snake here, scurrying around the mountains with Yunyue. Except for Master Geng's land just now, he didn't dare to be arrogant, and he was very familiar with everywhere.

Yun Yue looked at the place Chu Dayong pointed, and several huge caves appeared in front of him. The mountains are hollowed out, and I don't know whose idea it was. The clay is rubbed on the rocks and baked at high temperatures. The clay actually turned into ceramics, and it seems that it won't be long before Yun Yue can use porcelain. Ox carts wind their way down the paved mountain road. They were all loaded with half a cart of very high quality coal.

"Why is it only half a car?" Yun Yue asked a little puzzled.

"Some of the roads are uphill and the oxen can't pull it. There is no way, only half a car can be loaded. Chu Dayong was a little helpless.

"It is also difficult to transport iron ore to the steel mills, in order to get help from the mountain breeze. Our steel mills are all in good health in the mountains, and it is really difficult to transport ore, and the same is true for the finished steel to be transported down. This year alone, no less than 200 cows died of exhaustion. There were also several accidents in which dozens of people died. Master Geng was also a little helpless.

The amount of work involved in building mountain roads is so great that more than 100,000 people don't even think about it. Some places are still valleys, and even if you don't have the spirit of Yugong, you have to dig for a hundred or two hundred years.

"We can use a ropeway, which is to thicken the wire rope. Then hang this pulley, and the things hanging below do not have to be too heavy. One or two hundred catties is good, and the speed of sliding down the ropeway will be very fast. A winch will be required to go up the hill, and the speed will be fuller. However, it saves time and effort, as long as a few more ropeways are built, the efficiency can still be guaranteed. ”

Yun Yue folded the branches and simply sketched a figure on the ground. Master Geng got up with a thud and threw Yun Yue on the mountain. Running down the mountain without his life, a thin Qiang slave was actually knocked up and flying by him. The same was true of his apprentices, who descended the mountain like wild boars.

This is what the craftsman looks like, and when he gets a new knowledge, he seems to see a beautiful woman who has been stripped naked. I can't wait to get it immediately, and look at Chu Dayong in a blink of an eye. This thing is salivating and watching the Qiang girl under the mountain taking a bath!

Master Geng ran away, and Yun Yue was taken around by Chu Dayong in Jiguan Mountain. Cockscomb Mountain is indeed a good place, although the Yun family's castle is a bit of an eyesore, but the empty valley here is secluded, birds and apes are singing. The mountain spring water has a sound of "ding dong" in the mountains, and it is indeed a good place to travel. It's just that the huge pillars of smoke on the top of the mountain are a bit of an eyesore.

Fortunately, Yunjia Iron and Steel Plant burns coke. Otherwise, the rare mountains and forests in the lush northwest in front of you are already bare.

There is a flat land in the middle of the mountain with some unknown plants planted on it. Several huts are located in between, and a few people are turning the ground in the yard. A handsome girl in a red dress is eye-catching.

Chu Dayong, the evil ghost in the color, saw this woman in red really seemed to see a ghost. The mouth is tightly closed, not at all like the usual chatter just now!

Yun Yue straightened her clothes and said to the girl in red: "Qianqian has grown so big, is your grandfather at home?" ”

The girl who grabbed food with her grandfather back then has now grown into a disaster for the country and the people. You have to have a face, a body and a figure. But Yun Yue heard that this girl is eccentric. The sisters in the family are not afraid of heaven and earth, they are afraid of this Qianqian girl.

It is said that Xiaoya was sick once and invited Bian Que. It was this Qianqian girl who came, and the little girl muttered a few words. Qianqian left a few pills and left, and the helpless little girl vomited and diarrhea after eating, and vomited whatever she ate. I was about to faint from dysentery, so I sent someone to look for it, but they said that the medicine was applied externally.

Now, Qianqian specializes in treating the women in her family. No one dares to disobey the rules, otherwise you know if the medicine she prescribes is applied externally or his mother internally.

"Grandpa is in the house, that black charcoal head. You dare to come to my house, the medicine powder last time was strong enough! Put on a little more this time, and it'll tickle you to death! ”

Yun Yue looked at Chu Dayong with some suspicion, and this thing was so frightened that he hid behind Yun Yue. was scolded for being black and charcoal, and he didn't dare to fight back, looking like he was beating and scolding his little daughter-in-law, which looked a little ridiculous. General Chu, who kills people without blinking, is actually afraid of a little girl.

Looking at Yun Yue's puzzled eyes, Chu Dayong said with Ai Ai: "Once I was hunting in the mountains, I met Miss Qianqian who was ...... Bathe! ”

"And you'll survive to this day?" Yun Yue's eyes widened, and her sister almost died of the scourge. It is a miracle that Chu Dayong has survived to this day.

"Master Hou, life is better than death!" The iron-clad man actually cried like a doll in the month. (To be continued.) )
