Zhou Lang Zhou Lang

What Li Mu said about "the rest", actually she had thought about it when she went down to the Pi, but she didn't want to show off in front of Sun Ce at that time, and when she arrived in Wancheng, she had to spend a few days with Zuo Ci, so she was delayed all the time. down.

The physical dynamics after thousands of years, in addition to calculating the range of bows and crossbows, has a similar but more practical purpose.

Trebuchet.

The trebuchets of this era just use the leverage of a thick piece of wood to pull one end by manpower to throw out the stones mounted on the other end.There is no counterweight balance, no range, and no calculation of wear resistance. Just throwing stones outward often uses a lot of labor, and the casualties caused by the thrown stones may not be remembered. The rough wood suddenly breaks and collapses and injures human life.

The lever counterweight and the parabolic trajectory, and the influence of air resistance within the allowable error is tantamount to excluding the aerodynamics that she is not very good at. The only thing that Li Mu needs to trial and error is the throwing pole. Timber bearing problem.

For several days in a row, Li Mu summoned all the craftsmen in the city, directly set up a schoolyard in the city where Liu Xun used to practice soldiers and horses, set up a work shed, and started a furnace to cast iron.

A throwing pole is used as a lever, and a bracket is used as a fixation. If wood is used, it will not be durable, and if iron is used, it will be difficult to transport during the march. It is a dilemma.

Before Sun Ce arrived, the statement of breaking with Yuan Shu was the first to spread. He accused Yuan Shu of plotting to usurp a rebellious minister.Yuan Shu was furious when he heard this, and immediately sent general Ji Ling to bring up troops, intending to destroy Zhou Yu first, and then take Sun Ce.Zhou Yu had already come to Yuan Shuhui when Sun Ce sent messenger soldiers, and before Ji Ling led the troops to the city, he ordered a thousand cavalry to meet him.

In just a few days, there have been many battles.

Although Ji Ling has tens of thousands of soldiers and horses, they are all infantry. As long as there is a slight distance between his front and rear troops, Zhou Yu will appear there.The cavalry rushed back and forth, and when he reacted, he mobilized his army to encircle him, and then galloped away on his horse, leaving only dust in the sky, covering his head and face.Disturbed by Zhou Yu's whirlwind hit-and-run harassment, Ji Ling could only camp on the spot, traveling less than twenty miles a day, lest Zhou Yu find an opportunity.

It's just that, just like Li Mu's joke before, he was fighting outside all day long, and all the trivial matters in Xunyang City really fell on her alone.

It was the autumn harvest season, and Li Mu had to keep an eye on the progress in the work shed, and how much of the newly harvested millet would be used as military rations, how much would be kept for storage, and how much would be distributed to the families of soldiers in the army, together with Zhou Yu and his colleagues. How many casualties Liu Xun had left during the battle had not yet been compensated, what were the casualties of the soldiers who fought with him in the past few days, and how were the people who came to join the army from neighboring counties settled? She ran around the city in the name of Sun Quan, almost non-stop.

It wasn't until a soldier came to report that Huang Yun wanted to see her that she suddenly remembered that there was such a person in the city.

Because Li Mu pointed out that she was not a man, Zhou Yu did not detain her in the barracks, but found another house and surrounded a courtyard by himself to house her.

It is said to be a courtyard, but it is actually just a room with two mulberry trees surrounded by a two-person high earthen wall. I don’t know which general Liu Xun lived in before. There is still a stick on a weapon rack at the door A wooden gun that is half the size of its normal size.When Li Mu stepped into the gate, he walked past the weapon rack. He felt that the workmanship was exquisite, the gun tip had red tassels, and the handle was still vaguely engraved with patterns, so he couldn't help but take another look.

However, when she walked into the courtyard and saw the wood chips all over the ground, and the figure squatting on the ground with the hem of her clothes on, she immediately understood that the wooden gun outside was not left by Liu Xun's generals at all.

"You... all did this?"

Hearing the human voice, Huang Yun, who was almost buried by the pile of sawdust, raised his head. Seeing her, he froze for a moment, then raised his eyebrows and smiled: "I thought you wouldn't come."

She stood up, carefully patted off the sawdust standing on her body, and gave a salute to Li Muxian: "I haven't greeted you far away, please forgive me for being rude."

Li Mu hurriedly returned the gift, suddenly feeling a little funny.

Here, the two women dressed in short brown and bowed to each other with the courtesy of a man. I am afraid that they will not be able to find such a scene in this era of wars and gunpowder.

"I know you're busy, so don't gossip," Huang Yun smiled again, turned around and took the broom and carefully swept away the piles of sawdust on the ground, "I want... with this thing, I will ask you for advice on how to shoot at four hundred paces." Forget it, do you know if it is possible?"

This is……

Li Mu looked at the sawdust that covered almost half of the yard in front of him... It turned out to be a wooden carved city model that had been shrunk by countless times!

The city wall is only palm high, the saw-toothed pheasants on the top of the wall and the gazebos at the four corners are small and exquisite. There are rows of houses in the city with cornices and corners, drawbridges and waterways. Clearly.

"Thanks to Mr. Quan for treating the prisoners leniently, no one would be embarrassed to ask for some broken wood." Seeing her surprised, Huang Yun pursed his lips and smiled gracefully, and raised his hand to straighten his temples. "It's just that I came in a hurry and didn't look carefully. If there are omissions, you have to do it yourself.”

She leaned over and held down a city wall with one hand, and with the other hand, she took out the square wooden block with the cornice roof carved inside, and handed it to Li Mu.

Or is it detachable?

"The calculation of the range of [-] steps is related to the secrets of our army. You are from Jingzhou, and I must take Jingzhou. If you were me, would you tell me the calculation because of this wooden city?" Li Mu asked On the surface calm, in fact secretly frightened.The dismantled piece of wood is turned over, and there is a row of wedge-shaped dark notches underneath, and there is also a notch on the inner side of the city wall. When the two places are nested together, the house is buckled into the city wall. In this way, this wooden sculpture Any building in the city can be moved at will.

In other words, this city can now be Xunyang, and with a few changes, it can easily become Jichun, E County, or even Xiangyang, the ruler of Jingzhou.

Li Mu didn't know how Zhou Yu deployed the city before the siege, but she had seen the map with circles and lines that looked like ghost symbols. If no one explained it, she might not be able to see what was drawn even if she stared at it for a day. Come.And if there is this woodcarved model city, it will undoubtedly be much more intuitive.

This model city is actually the same principle as the building block toys of later generations, but she claims to have experienced modern education 800 years later, but she never thought that this method can be used to replace the dizzy map she has been looking at. !

He has always had an indescribable sense of superiority, but at this time he was hit hard by an ancient man.

As if expecting that she would not agree, Huang Yun didn't show any disappointment, just shook his head: "Forget it, why don't I know that this matter is unspeakable. If it weren't for the angle of the shot, the strength of the bow, and the length of the crossbow I've tried and calculated, but I can't find a general method in the end, I can't figure it out..." She paused, sighed softly, then raised her eyes and smiled slightly, "This thing is just to thank you for looking after me. Can I let you know when I also make something for real military use?"

Speaking of military items, Li Mu's heart suddenly moved: "I have something, if you can answer it, I will tell you how to calculate the range of a bow and crossbow."

Seeing that Huang Yun's eyes lit up, she put the wooden block in her hand on the ground, then turned around and brought in the wooden gun at the door, put it on the wooden block, and made it the simplest lever. Press, made a gesture, raised his head and asked: "If I want to use this spear to pick up a basket of stones, how can I keep the gun body unbroken?"

Huang Yun stared at the wooden gun, pondered for a moment, and suddenly his eyes froze: "Do you want to calculate the range of the trebuchet?"

Li Mu couldn't help but chuckled and nodded when she saw her right away.Who said that women in this era don't understand military affairs and don't care about world affairs.This Huang Yun knew that she had calculated the range of [-] paces for one arrow, and knew that archery needs to be adjusted by looking at the mountain, and he can also chop wood with a knife.

"I can't tell you this algorithm no matter what." Li Mu said plainly.The [-]-step arrow shooting is based on the crossbow and bow string. Even if it is as strong as a city crossbow, it will be scrapped with just one arrow. The lethality of reloading weapons is too great.

"Have you ever tried casting a throwing pole out of refined iron?"

"Three feet of iron weighs a thousand jun, how can it reach the front army during the march?"

Casting iron throwing poles was also Li Mu's first reaction, let alone whether she had so much pig iron that could be used as throwing poles in this era when pig iron was an important military item. With a force of 3000 men, it would take more than half of the effort to transport the throwing poles, so why fight?

Huang Yun's eyes fell on the city model on the ground: "Then if this throwing pole...can be disassembled and transported separately?"

Li Mu's eyes suddenly lit up.Naturally, it is still heavy to transport them separately, and she still knows that soldiers are expensive and fast, even if she doesn't know the art of war, how can she be fast with such a large piece of armament?But as long as disassembly is considered, she can just use iron to cast the load-bearing joints on the throwing pole that are prone to wear and tear, and other parts are made of wood, and then assembled with this nested wedge-shaped notch, and even It can be fixed with screws. If you can't make iron screws that fit perfectly, you can at least use wood to grind out the screw lines to make wooden nails!

It was really a word that awakened the person in the dream, Li Mu felt suddenly enlightened.

Seeing that Li Mu's eyes were getting brighter, and his determined smile seemed to be contagious, Huang Yun also laughed along with him: "This time, if I bring back your method of shooting arrows, we will have to fight again on the battlefield!" See high and low!"

Her complexion is slightly dark, but her eyebrows are delicate and delicate, so the man dressed up with a bit of a scholarly air, and when he mentioned the battlefield, his expression was flying, and he also had a heroic air, which made Li Mu follow suit. Raising eyebrows: "Then I'll wait for you."
