Immediately, the table was set up and the paper, ink, paper and inkstone were served.
It is always prepared in case inspiration comes at any time, so it is of course very fast.
Xia Yu sat down and was about to pick up the pen, but felt that the sun was shining brightly above her head, and she was wearing an official uniform, covering her head with stinky sweat.
"Nima, this damn weather is too hot!"
"Quick, don't you think it's too hot, military advisor? Hurry up and hold an umbrella! Bring a fan too!" Yu Wenshiji quickly shouted around enthusiastically.
This old man also has no moral integrity and is very dishonest in order to steal his master.
Immediately, the umbrella was brought, held up, and the fan started fanning vigorously. Xia - pretending to be cool - Yu was finally satisfied.
He picked up his pen and drew the rough outline of a counterweighted trebuchet.
It only takes a moment and it's done.
When he looked up, he saw that the surroundings were filled with water. Everyone's eyes were wide open, as if they wanted to eat the drawings.
"That's the pattern, and the principle is very simple."
"It is an improvement on the lever principle, and a counterweight of hundreds or even thousands of kilograms is added to one end of the lever as a force source."
"Before launch, use a winch to raise the counterweight, and then use a machine scraper to fix the counterweight."
"After loading a stone bullet on the other end, use a hammer to smash the mechanism open. The huge counterweight will suddenly fall, and the stone bullet will be launched."
Xia Yu felt proud.
This thing is very simple to explain, but if no one points it out, hey, it will be enough for the world to ponder for hundreds of years.
But now, this thing belongs to him.
Even God can't take it away.
"Wonderful!"
Yu Wenshiji gave a high-five and said ecstatically: "It turns out it's so simple. Why can't we pigs think of it!?"
Xia Yu was stunned: Are you using pig brains to describe people as stupid now?
"The military advisor is really wise, I can't wait." Li Shiji was also impressed with his admiration.
He is also a conceited person who never lags behind others in anything.
However, the problem that has caused countless people to scratch their heads for hundreds of years was easily solved in Xia Yu's hands in the blink of an eye.
This crushing of wisdom made Li Shiji feel quite frustrated.
"No, no, it's just a small skill." Xia Yu was very humble, but this pretentious person could already get full marks.
Yu Wenshiji picked up the drawing and handed it to the craftsmen: "Make it immediately according to the drawing. Remember, be quick."
"promise."
"Also, this is the secret knowledge of Guigu, the most precious treasure in the world. You are all the confidants of the imperial court and must be kept strictly confidential. Anyone who dares to leak it is the Yi clan!" Yu Wenshi said with a stern look.
"No." All the craftsmen said in awe.
Xia Yu didn't say anything. He knew that Yuwen Shiji was right. Any new weapon that could be kept secret for one more day would have huge benefits.
Just as the craftsmen were about to disperse, Xia Yu suddenly remembered something: "Wait a minute, don't leave."
"Any further instructions from the military advisor?" Yu Wenshiji asked hurriedly.
"Yes." Xia Yu scratched her long hair: "Weapons are important, and ammunition cannot be ignored. What ammunition did you use before?"
"Commander, please take a look." A young craftsman quickly took out a round stone bullet.
Xia Yu took it in her hand and felt it sink. It seemed to weigh five or six pounds. She couldn't help but asked in surprise: "Is this the only one?"
"Yes." Yuwenshi said: "When convenient, use stone bullets. In emergency, clay bullets can also be used."
"You guys have no imagination." Xia Yu reproached her.
"Uh, please give me some advice from the military advisor." Yu Wenshiji blushed. Although he was a little embarrassed, learning is a journey, and those who are masters are teachers.
If you are not as skilled as others, what can you do if you are not humble?
"I'll teach you several types."
"The first type is stone fire bombs. Coat the stone bombs with a layer of tung oil and ignite them before firing. In this way, in addition to killing people and destroying cities, they can also set fires."
"The second type is arson bomb. Use a narrow-mouthed clay pot, fill it with tung oil, and stuff the pot with straw."
"Before launching, light the straw. The clay pot will explode instantly if it hits the ground. Not only can the fragments hurt people, but it can also turn the surrounding area into a sea of fire, which is difficult to extinguish."
"The third type is poisonous smoke balls. You can pound sulfur, grass black, croton, wolfsbane, arsenic, asphalt and other highly toxic and flammable substances into balls, and wrap them with hemp rope soaked in tung oil."
"Before launching, set it on fire. After landing, the poisonous smoke will rise everywhere. If you smell it, you will cough violently, your mouth and nose will bleed, and your combat effectiveness will be greatly reduced."
Seeing Xia Yu's words flying with saliva, the panic in everyone's eyes was beyond words.
Military advisor, are you a devil?
You are using such vicious ammunition one after another! What kind of dark mind do you have to think of such terrifying things?
Whoever wants to be your enemy will have bad luck for eight lifetimes!
"Huh!?" Xia Yu also felt that something was wrong. Why did everyone look at him with a look of horror as if he had seen a ghost?
"Why, are you scared?" He was a little confused and said with disdain: "I'm telling you, those people from the Western Yi Kingdom are even more ruthless."
"They would use trebuchets to shoot rotting corpses, preferably those suffering from plague, smallpox and other horrific diseases, into the city."
"As a result, the city will soon be plagued by disease. Sometimes, even without a strong attack, the entire city will die."
ruthless!
Too cruel!
Inhumane cruelty!
After hearing this, everyone felt cold all over, and their backs were so cold that some people even had their legs weak and sat down on the ground.
Xia Yu was a little funny.
This simple guy thought for a moment that he was in modern times, simply discussing and discussing military academic issues.
Before he realized it, he had opened Pandora's box.
His casual words will be used by countless people one by one, and countless people will lose their lives.
"Look at how scared you are, I'm just kidding you." Xia Yu laughed mischievously: "This way of spreading the disease is harmful to people, so of course it shouldn't be used lightly."
"And if you don't do it well, not only will the enemy be killed, but you will be finished as well."
"Okay, it's getting late, I've taught you everything, and it's time for me to retire." Xia Yu stood up and stretched.
After the addiction of being a teacher, it was time for him to go back to eat.
By the way, wearing this official uniform is so damn hot!
When Yu Wenshi came back to his senses, the old man bowed solemnly: "The military advisor's innovation of the trebuchet is a great contribution to the state. When I succeed in the trial production, I will definitely ask for credit for the military advisor."
"It doesn't matter, the boss will take care of it."
Xia Yu waved her hand with no interest. What others regarded as a treasure was just one of thousands of golden fingers to him.
"Okay, everyone, I say goodbye. Zhang Yu, let's go back."
Looking at Xia Yu's back as he mounted his horse and walked away happily, Li Shiji twitched the corner of his mouth and said with emotion: "They say we are ruthless warriors, but compared to military advisors, we are simply pure and good!"
"..." Yuwen Shiji was dumbfounded, then laughed and said, "Mr. Mao, are you a good person?"
"As far as I know, you started a rebellion at the age of 17, killed people, set fires, and robbed people. At the age of 20, you were already a general in Wagang and a powerful leader."
"If you are pure and kind, then I will be nothing more than a little white rabbit."
Li Shiji: "..." Is it possible to curse people without revealing their shortcomings? Isn't it true that a certain family rebels because of troubled times?
"Sir, sir," Li Shiji squinted his eyes, wanting to scold his mother: "If you continue to ridicule a certain family, you will no longer be friends."
"A certain family is not a good person, and your Yuwen family is not much better! Hehe, your brother Yu Wenhuaji——"
Yu Wenshi suddenly felt as if he had been stung by a bee on the butt, and quickly begged for mercy: "Mr. Mao, stop it, stop it, I made a mistake! Isn't it a mistake to make a mistake?"
Yu Wenhuaji forced Emperor Sui Yang to death and rebelled and usurped the throne. He was a very treacherous official!
If everyone hurts each other, Yuwen Shiji will obviously suffer more.
"Huh!" Li Shiji snorted proudly: In troubled times, everyone is trying to survive, and no one is whiter than the other.
Yu Wenhuaji quickly changed the subject: "However, Mr. Mao, you are right." He lowered his voice and said, "I also feel that the military advisor is someone you can't offend. If I were to become his enemy, I might have to open one eye even when I sleep in the middle of the night."
"I feel the same. I feel the same." Li Shiji said with lingering fear: "The military advisor is so intelligent that it is almost demonic and unfathomable. You can only make friends, not enemies."
At that moment, the two thousand-year-old foxes nodded sympathetically.
"Military advisor," Zhang Yu suddenly said on the way back, "Did we forget something?"
"What's the matter?"
"Lunch." Zhang Yu looked at the sun and said, "I think if we don't hurry up, we will be hungry at noon."
"..." Xia Yu suddenly realized that he felt ashamed because he was busy pretending to be cool.
"It's okay. If you run faster, you should still be in time." Xia Yu looked kind and caring, as if the pot had nothing to do with him.
"..." Zhang Yu was speechless: Sure enough, the head of the family is never wrong, and the blame is always placed on his subordinates.
"Uh, you're not going yet?"
"No." Zhang Yu raised his head and looked at the scorching sun, sighed in his heart, had no choice but to accept his fate, hit his horse and ran out.
Xia Yu nodded with satisfaction, a subordinate who has the courage to take the blame for his boss is a good subordinate.
