The old fisherman became very interested in the sheepskin bag. In fact, the main function of the sheepskin bag was to tie up rafts. In the upper reaches of the Yellow River, sheepskin rafts are a very common tool for crossing the river. I don¡¯t know what Wu Yuanshuang¡¯s imagination was like, but he actually thought of using this thing to hold gasoline.
The sheepskin bag was tied tightly and there would be no problem no matter how it swayed in the carriage. When Yunhao saw the old fisherman, the old man was instructing people to load the sheepskin bags onto the trebuchet.
"You came just in time, this thing is really good. You are so smart, why didn't you think of such a good way? I just tested it with water in the trebuchet. Twenty or thirty kilograms of things will affect the range. This kind of range , it will be easily destroyed by the Eight Oxen Crossbow on the city wall. Taking advantage of the height, the Eight Oxen Crossbow on the city wall always has a longer range than the one on the ground." Just as the fisherman finished speaking, the trebuchet behind him "creeped" A sound. A sheep-shaped ball was thrown out.
It only flew about two to three hundred steps before falling to the ground. Gravity caused the sheepskin to crack and the water inside flowed all over the floor.
Yunhao stroked his forehead and just said that he was not clever. The sheepskin is too big, why don't you change it to a smaller one? Rabbit skin is good. Generally, it should be no problem if it weighs three to five kilograms. The gravity lever trebuchet can send this kind of thing a thousand steps, let alone the Eight Ox Crossbow, even the Eight-One Bar can't reach it.
"Old Fisherman, what do you think about replacing the sheepskin bag with rabbit skin? The cost is cheap, and rabbits reproduce quickly. A pair of rabbits can have a litter in three or two months." Yunhao smiled and handed over his hand, hoping to get the old man's skin. Praise from the guy.
Unexpectedly, the old guy slapped Yunhao on the back of the head. "You have such a good idea, why didn't you tell me earlier? It made me work all day in vain!"
"The boy just arrived!"
"Then I'll beat you up, too, right?"
Unable to offend the angry old man, Yunhao decided to talk to fishermen, young and old in the future. The Tang Dynasty was founded on the principle of filial piety. Old people like this were walking sideways in Li Yuan's Jinluan Palace. In the academy, Mr. Yu is like a crab. Poor Wen Daya wanted to make a shrine for this old gentleman.
"Hey! I'm worried! The battle report came from the front line of Luoyang. The city cannot be attacked for a long time and we have to besiege it." Seeing the aggrieved look on Yunhao's face, the fisherman sighed helplessly.
"Doesn't Momen advocate universal love without attacking? Why are you suddenly interested in killing in battle formations?" Yunhao looked at the old man in confusion, this kind of thing should not be the old guy's excitement.
"What do you know? People will die in a battle, but the number of people who will die is limited after all. The military laws of the Tang Dynasty are strict, and massacres will never happen in the Central Plains.
But it is different in the siege. The first people to reduce rations are ordinary people. Those in power will always work hard to ensure that the troops are fed and clothed when there is no food to eat. People become food! In the history of sieges, there have been many tragedies of cannibalism.
¡°You think I like to study this murderous weapon? But you can't save people without killing people. Only by quickly capturing Luoyang can the tragedy of Zhu Mi be prevented from happening again. "
Yunhao solemnly gave the old guy a deep bow. Although the theory that killing people can save others seems unreasonable. But it is something that really exists. In my previous life, I watched a rather ridiculous movie called "Hero", and the principles discussed in it were similar to those of the old fisherman who arrived at the same destination through different paths.
In times of war, only great unification can reduce killings. I thought the old guy wanted to be loyal to the Li family dynasty, but I didn't expect that the old guy was the real fraternity. Only when the Tang Dynasty of the Li family dominates the world will the killings in the troubled times of the late Sui Dynasty stop. No wonder the old guy worked so hard on researching murder weapons.
"The sulfur purification thing you mentioned is still a big problem. The production efficiency is too slow. At this efficiency, we can't produce a few hundred kilograms a year. This is the result of two hundred people working in shifts!" The fisherman was helpless. , purifying sulfur has exceeded the scope of his knowledge. The output of several hundred kilograms is definitely the result of non-stop work.
"Don't worry, gunpowder is a new thing. If you want to get good gunpowder, you have to start with stupid methods. Then gradually simplify it step by step. Everything has an accumulation process. I believe that if we continue to study at the current speed, It¡¯s amazing that in three to five years we will be able to find a suitable method to purify sulfur.¡±
When computers first came out, they were as big as a three-bedroom apartment and weighed thirty tons. Your computing power is only five thousand times per second, a few decades later. A smartphone can be carried in a pocket, and a kindergarten doll will have no problem holding it and playing with it. The computing speed is tens of millions of times faster than before. I read the novels "Lazy Tang", "Usurping Qin" and "Han Xiong" without feeling tired at all.
There was no way to tell Mr. Yu about the evolution of computers, so Yunhao could only briefly talk about it. I hope the old guy can draw inferences from one instance, and only those who have accumulated a lot of experience can make researchers better.??The right attitude.
Old Yu nodded in agreement, it was indeed the case. Many things are extremely complicated when they are made. Finally, little by little, it becomes simpler and more efficient.
"Actually, there is something like kerosene, which can already cause imbalance on the battlefield. We were in trouble before. Although Wu Yuanshuang is so bad, he still has a bright mind. If the incendiary bombs made of rabbits are too small. We can use pig urine, sheep urine and other things. In short, the practical application of kerosene has taken a big step. I believe that when this thing comes to the battlefield, whether it is infantry or cavalry, it will appear in their most terrifying nightmares. .¡±
The truth makes sense, and the two guys, one old and one young, no longer have to worry about each other. Yun Hao, a veteran fisherman, studied the idea with several Momen disciples and found it very feasible. Several guys quickly looked for urine bubbles for experiments!
That thing is inedible, so it should be easy to make. Regardless of cost, there is no problem with elephant urine bubbles.
After a day and night of experiments, Yunhao and Yu Lao unanimously concluded that soaking sheep urine is very good. The main reason is that the elasticity of sheep urine bubbles is relatively good, which may be related to the habits of sheep. Pigs usually urinate immediately when they have urine, while sheep generally do not urinate while sleeping.
The trebuchet easily carried about ten kilograms of water-filled sheep urine to a distance of 800 steps, filled it with gasoline, lit the fuse and threw it out. The range actually exceeded that before. Yunhao thought this was because gasoline was lighter than water. The skin bag dropped to the ground and bounced a few times, and then an orange fireball rose into the sky. Countless flames burned wherever they splashed. This is the result of adding icing sugar. Yunhao and Yulao are very satisfied with the experimental results.
Large-scale incendiary bomb manufacturing was immediately put on Wen Daya's agenda. To this end, Li Yuan assigned hundreds of death row prisoners to the academy. Li Yuan was determined not to repeat the last leak. (Remember the website address: www.hlnovel.com
