Xia Yu continued to wander, from the front camp to the middle camp.
At this time, it was almost noon. Although autumn had already entered, the sun was still very strong, and Xia Yu, who was so hot that he was sweating all over, enjoyed it endlessly.
Zhang Yu looked helpless.
He could tell that if the military advisor didn't take a tour of the entire camp today, it would probably not be complete!
Poor him, he almost died from the sun.
As he was walking, he bumped into another general in front of him, but it was Chai Shao.
"Hey, General Chai, where are you patrolling the camp?" Xia Yu greeted warmly again.
"I've seen the military advisor. What are you?" Chai Shao, as a son of a noble family and the chief consort of the Tang Dynasty, was extremely well-mannered and quickly returned the greeting.
"Oh, patrolling the camp, patrolling the camp. If you are busy, I will sneak away."
Camp patrol!?
Chai Shao also looked stunned.
Then I saw that Xia Yu was wearing a brand-new official uniform, covering her head tightly, while she was wearing cool civilian clothes, and she suddenly realized.
"Okay, okay, it's up to you, military advisor." Chai Shao smiled secretly in his heart and handed him off.
Seeing Chai Shao's understanding eyes, Xia Yu knew that Chai Shao understood him and left happily.
In the handsome tent, Li Shimin was dealing with official duties. With a camp of nearly one hundred thousand people, even if it was just to make a decision, there were many things going on every day.
There was a large pot of herbal tea on the table, and there were guards on the side helping to hold fans.
Fighting on this hot day is also punishable by death.
"Your Highness."
At this time, the tent was darkened, and Zhang Ananda floated in silently like a ghost.
"Is something wrong?"
Li Shimin didn't even raise his head, but he knew that if nothing happened, Zhang Anan would not say a word and would just stay on the sidelines.
"Well, I just saw the military advisor."
Li Shimin raised his head, a little baffled. They were both brothers fishing for the horse from the same pot. What's so strange about seeing this so often!?
Meeting Zheng Jun in the camp is a big deal!
Zhang Anan said with a strange look on his face: "The military advisor was wearing official uniform and riding a Tengshuangbai horse. He wandered from the front camp to the middle camp, saying he was patrolling the camp."
Li Shimin: "..."
As the extremely smart Qiangu first brother, Li Er immediately understood someone's little thoughts and looked a little dumbfounded.
"That's all, as long as the military advisor is happy."
Li Shimin held back his laughter, is it understandable for a young man? Perhaps, this is how he is a normal person of flesh and blood.
"Well, send some herbal tea to the military advisor. It's too hot, so don't get heat stroke." He added.
Zhang Anan almost laughed out loud when he heard this.
Zhang Yu guessed correctly.
Xia Yu walked from the front camp to the middle camp, and then from the middle camp to the back camp. She really wanted to survey the entire camp.
"Commander, it's time to have lunch." Zhang Yu, who was too hot, couldn't help but said.
He was thinking: Can we go home after a while!?
However, Xia Yu did not answer. Zhang Yu turned around and saw Xia Yu looking forward with wide eyes and surprise.
It turned out that there was a huge, strange-looking wooden instrument standing in the open space ahead.
There was a group of people surrounding them, led by Yu Wenshiji and Li Shiji, and the others were craftsmen wearing coarse cloth and Geyi.
Zhang Yu was a little confused: It's just a trebuchet. It's common in the army. Is there anything strange about it?
Ancient trebuchet!
Xia Yu's eyes shone brightly, and as soon as he defeated the horse, he ran up happily. He looked like a three-year-old child who saw a toy.
"Military advisor, don't you want to eat anymore?" Zhang Yu still refused to give up.
"We'll talk about it later." Xia Yu didn't even look back.
He has always been interested in various ancient weapons. Now, he can see the most authentic ancient trebuchet with his own eyes, and eat and so on. What a heck!
Hearing the noise, Yuwen Shiji and Li Shiji turned their heads.
Xia Yu saw the general coming over like a gust of wind, jumped off his horse, and walked up and down the trebuchet with bright eyes, looking left and right.
The two couldn't help but laugh. Yu Wenshiji smiled and greeted: "Strategy! Strategist!"
After shouting twice, Xia Yu came back to her senses and said apologetically: "Master Yuwen, General Li, I am laughing, I am laughing, I am fascinated by it."
"The military advisor is also interested in this trebuchet?" Li Shiji asked.
"Of course." Xia Yu's eyebrows were full of excitement: "As the saying goes, a good horse is a man's lover, and a weapon is a man's romance!"
Yuwen Shiji and Li Shiji: "..."
They had never heard of this, but it seemed to make sense, and it spoke to everyone's hearts.
"Military advisor's wonderful talk." The two of them could only give a thumbs up.
"By the way," Xia Yu said with great interest: "You two are here, are you studying this thing?"
"Exactly." Yu Wenshi said: "Luoyang is a great city in the world. It is high and thick, easy to defend and difficult to attack. We are thinking that the stone throwing machine will be of great use, so we are thinking of making some improvements."
He is in charge of the craftsman's camp and it is his duty to improve the trebuchet.
Xia Yu nodded, there was nothing wrong with that.
In ancient times, attacking a city was a hard job, especially attacking one of the most powerful cities in the world like Luoyang, which was even more difficult.
The trebuchet, as the most lethal long-range weapon before the emergence of artillery, naturally had high hopes.
If the trebuchets could quickly destroy the Luoyang city wall, not only would the Tang army lose many lives, but the war would also end earlier.
"Two distinguished experts. So, can you get anything out of it?"
"Not yet." Yuwen Shiji looked regretful: "I have summoned the best craftsmen in the camp and have been thinking about it for a while, but I still don't have a good idea."
"Today, thinking that General Li has always been resourceful, I invited him to join us as a consultant."
Xia Yu was not surprised.
According to his research, trebuchets have been around since the Warring States Period, but it took nearly a thousand years for them to mature during the Sui and Tang Dynasties.
A major innovation in an important weapon is not that easy!
"Master Yuwen, you have thought nothing of it. If you want to improve the trebuchet, come to me!" Thinking of this, Xia Yu complained.
Yu Wenshiji was stunned: "The military advisor also knows about trebuchets?"
"That's right." Xia Yu said proudly, "I am a disciple of Guigu, I am very good at all the trap skills and Qimen Dunjia."
Although he used Guigu to block the gun, he really understood the trebuchet.
From the Warring States Period to the Sui and Tang Dynasties, although Eastern trebuchets became increasingly mature, they were always of the single-shooter type and were launched using the lever principle. This device had a simple structure, but was tall and bulky, and had a limited range of only 150 steps (230 meters).
.
It was not until the Mongolian Eastern Expedition in the 13th century that the Western counterweight trebuchet was introduced, which was the historical trebuchet. This new type of trebuchet has been greatly improved. It not only has stronger throwing power, but also has a longer range, reaching up to
Three hundred and fifty steps (530 meters)!
But then, there was nothing more.
With the rapid rise of artillery, the trebuchet, which had no advantage whatsoever, was brutally eliminated.
Yu Wenshiji was overjoyed when he heard this: "I would like to listen to the military advisor's opinions!"
Li Shiji and the craftsmen on the side also quickly pricked up their ears. Guigu's unique skills were really good, so they quickly learned from them.
Xia Yu instantly found the feeling of being a teacher again, and she talked happily.
"This trebuchet is not only available in China, but also in the Western barbarian countries thousands of miles away."
"We have always used this single-shooter type, which is launched based on the lever principle. But the Western Yi countries are different. They use a torque type."
"In other words, animal tendons or twisted ropes are used as the source of force. The structure is lighter, but the craftsmanship is complicated."
"I can't say which one is better between the two. I think they have more advantages."
God!
A group of people were stunned when they heard this. The military advisor was really well versed in Chinese and Western knowledge, and even had profound knowledge of the weapons of the Yi Kingdom thousands of miles away.
The Ghost Valley Gate is so scary!
"However," Xia Feng changed his tone and said proudly: "I, Gui Gu, have taken a different approach, but I have made important innovations."
"This new type of trebuchet is called a counterweight trebuchet. It not only has stronger throwing power, but also doubles the range."
"When fired, the sound is like a thunderbolt. Where the stone hits, the city collapses, the house collapses, and the ground shakes. Therefore, it is also called the 'Thunderbolt Chariot'!"
Holy shit! When everyone heard this, their eyes widened, it was so awesome!
"Military advisor," Li Shiji was even more excited than Yuwen Shiji when he heard this: "What kind of counterweight trebuchet is this? Do you have specific drawings?"
"Yes. Everything is in my mind." Xia Yu looked like she had a pearl of wisdom in hand: "Get a pen and paper quickly."
Yuwen Shiji was overjoyed: "The military advisor is willing to donate it?"
"Of course." Xia Yu coaxed very arrogantly: "This thing is not a good thing for my Guigu sect."
Everyone was sweating: Boss, if you say this, it’s very shocking, right?
Yu Wenshiji didn't care: you don't like it, but I like it! He said impatiently: "Great. Come on, the desk, pen, ink, paper and inkstone are waiting for you."
