Sun Ce nodded. Huang Yueying was very thoughtful. However, in this way, the size and weight of the stone throwing machine are very amazing, and if it is carried in by manpower, it will require a lot of force, and it may not be spread out when entering the city gate.

"Why don't you use a car?"

"Cars can't afford it, and it's too late to build big cars now. Even a large car can hardly bear such a weight. So I thought, first make the parts to size, ship them to the city, and assemble them on site. General ......"

Sun Ce raised his hand and signaled Huang Yueying not to speak in a hurry. "One car can't afford it, so why not try to transport it in multiple cars at the same time? Two is not enough, if not enough, four, four is not enough, eight, sixteen ......"

Huang Yueying rolled her eyes, reached out and grabbed Sun Ce's arm, dragged Sun Ce to the big tent on the side, closed the tent door, and whispered: "Don't talk nonsense about things you don't understand, okay?" I'm not afraid of being embarrassed. ”

Sun Ce was a little stunned for a while. "Hey, that's right, I don't understand?"

"What do you know?" Huang Yueying took a model of a small car from the side, and a model of a larger stone thrower, and put them in front of Sun Ce together. "You put the stone thrower on the car for me to try."

Sun Ce glanced at it and didn't move. There's really no way to put it. In this era, there were board cars that specialized in transporting goods, but the wheels of this era were very large, the flat plate was directly on the axle, the wheel was higher than the flat plate, and the size of the stone throwing machine exceeded the width of the wheel, if it was directly erected, it was not placed on the flat plate, but directly on the wheel.

"It seems that there are still not enough people in the baggage battalion, and so far we have not built a big cart that can load a stone thrower. However, craftsmen are not allowed to enter the city, it is too dangerous. Sun Ce crossed his hands and placed them in front of his abdomen. The Wood School led by Huang Chengyan and Huang Yueying is his engineering college, and the baggage camp is his engineering institute, and any craftsman is a treasure, and he is reluctant to let them risk their lives to assemble a stone thrower.

"The Wood Academy has already recruited some young students, and there will be more craftsmen soon, but it is far from being able to solve the near fire. General, make an exception and let them go into the city to assemble, you heard it just now......"

"I can't kill these hens that can lay eggs just to take the egg of Wancheng." Sun Ce stood up and waved his hand resolutely. "I will never allow them to enter the city until they are safe. If you really can't do it, you can attack outside the city, and then you can repair it. ”

"You ......" Huang Yueying stomped her feet angrily, turned around angrily, and didn't want to talk to Sun Ce anymore.

Sun Ce sighed lightly, got up and walked behind Huang Yueying, and pressed his hands lightly on her shoulders. "Achu, people can't stand without faith. Why are the craftsmen of the baggage camp working so actively, and why are they vying to send their children to the wood school? Isn't it because I promised to keep them safe and let them do things with peace of mind? Today, because Wancheng made an exception, let them take the risk of assembling a stone thrower, and next time it may be an exception because of something else, they are no longer safe, can they still be so positive? If I say it and can't do it, I'd rather not say it. ”

Huang Yueying slowly turned around and tilted her head to look at Sun Ce. "But what about Wancheng?"

"Didn't I just say it, but I really can't do it, so I'll attack from outside the city. As for the Xiliang soldiers, you don't have to worry, they didn't come in so quickly. You hurry up and finish the work here, and then arrange for your capable men to rush to Luyang and Wuguan to make equipment to defend the city and strengthen the city defenses. I will go to Wuguan after taking Wancheng and prepare to compete with Xu Rong. Achu, that is a famous general in the Xiliang army, my father was once defeated at his hands, you have to help me win this battle. ”

"Don't worry, I'll do my best." Huang Yueying grinned and said: "Isn't there a lot of cavalry in Xiliang, I have already thought of some ways to deal with the cavalry, which should be able to curb their advantage." ”

"Good." Sun Ce was very happy. "However, to defeat Xu Rong, it is not just about curbing the advantage of the cavalry, there is one more thing you have to pay attention to."

"What's the matter?"

"Retrofitting existing vehicles, it's better to ...... I can change it to a four-wheeled one. Four-wheeled vehicles can carry heavy loads and are well balanced, making them more suitable for defensive vehicles, even better if they are equipped with a crossbow or a small stone thrower. Achu, you have a heavy task on your shoulders. I have to pay close attention to the affairs of the Mu Academy, if I can have a few more talents like your father and daughter, I will be more confident. ”

Huang Yueying wrinkled her nose and muttered in a low voice, "You are really greedy." ”

"What did you say?"

"It's nothing, I know, I'll hold on." Huang Yueying grinned, and then said: "There are four-wheeled vehicles, which can carry heavy loads, are easy to balance, and have obvious advantages, but the problem of steering has not been solved." If you don't solve this problem, if you rely on pulling hard, the wheels will break easily. ”

"I'll give you a piece of advice, okay?"

"Okay, you can say it."

"Since it is a difficult problem, we must not rely on one person alone, but give full play to everyone's ingenuity. Think about it, why was the Cai family able to master a new knife-making technique in just a few months? ”

Huang Yueying's eyes lit up, her eyes showed surprise, and she clapped her hands and cheered. "Use the way of competition to attract more people to participate, work together, find the right direction, and focus on breakthroughs?"

"Clever." Sun Ce pinched Huang Yueying's nose. "I'm waiting for your good news."

A red cloud rose from Huang Yueying's cheeks, instantly enveloping her face, and even her neck turned red. She turned her back, wringing her fingers, squeaking, not knowing what she was saying. Sun Ce thought it was funny, but he didn't dare to tease her anymore. Huang Yueying's thoughts about him, he knows very well that women in the Han Dynasty got married early, and it was not uncommon for women to marry at twelve or thirteen, but he really couldn't do anything to a twelve or thirteen-year-old girl.

Sun Ce coughed, and said with a straight face: "Ask you a serious matter." ”

"Do you have anything else to do?" Huang Yuehuang's voice was as light as a mosquito.

"How are brothers Yang Xi and Yang Yi doing? If they are succumbed like Pang Shanmin, then bring them in. Yang Yi is talented in arithmetic and should be able to help. Achu, although wood science is a technique, it is also the basis of Taoism, and from the technique to the Tao, arithmetic is the key. You should know this very well, and I don't need to bother with it. Of course, Yang Yi is too young and has limited attainments in arithmetic, if you know where there are arithmetic masters, hurry up and ask, I can open a high salary of 2,000 stones. Note that I'm not talking about the kind of people who know a little bit about the skin, but people who are willing to devote their lives to arithmetic. Not only arithmetic, but also those who are well-versed in wood. By the way, last time you said that you were looking for Zhang Pingzi's posthumous work, how did it progress? ”

Huang Yueying turned around, although her face was still a little red, her eyes became serious. "I've been busy with the war, and I haven't had time to look for it. However, speaking of this, I forgot to remind you that Cai Bojiao's knowledge is not only scriptures and literature, but also very good at studying the problems of heaven and earth, since he is here, you have the opportunity to ask him for more advice. ”

Looking at Huang Yueying's shy appearance, Sun Ce couldn't help but reach out and tap her nose. "Thank you, Miss Achu."
