Zhang Fen was very serious when he worked, but he didn't talk much, except for the Jishu issue, he rarely took the initiative to chat with Wei Ba. Speaking of Yu Flip today, I also felt it, and after saying a few words, I probably felt that it was inappropriate, so I closed my mouth, and my slightly thick lips were tightly pursed, and my eyes were a little dazed.

He looked like Wei Ba was an engineer in his previous life, and he couldn't help but want to say a few more words to him.

"Yu Gong is proficient in metaphysics?" Metaphysics is the so-called geometry in later generations, and Wei Ba does not know that Yu is also proficient in mathematics.

"Yu Gong is an easy learner, good at easy images, and must be not shallow in metaphysics." Zhang Fen smiled embarrassedly. He rolled up his sleeves, his fingers were full of ink left by the drawing lines, and he squatted there, like a simple and simple craftsman, and he couldn't see the shadow of the children of the family at all. If he doesn't say it himself, no one will want to associate it with Zhang Zhao, who is proficient in "Spring and Autumn".

Wei Ba doesn't understand Yi Xue, let alone Yi Xiang, and he doesn't know whether Zhang Fen is right or wrong, but he is not too interested in the occult of Yi Xue, and he always feels that he is similar to a charlatan who tells fortunes on the street.

"It's hard to say, metaphysics is actually more pure mathematics, and it shouldn't have much to do with easy learning......

"I didn't think that joining the army would be easy to learn?" Lu Lan walked over, and just when she heard Wei Ba's words, she couldn't help laughing: "In this way, I want to learn from the army, I don't know if I want to be willing to appreciate my face." ”

Wei Ba smiled indifferently: "The captain will be disappointed, I don't know anything about Yi Xue." The Lu family is easy to learn, and I don't dare to laugh and be generous. Well, I'm just going to do some tricks. Let the captain see it and smile. ”

The Lu family is a Jiangdong wang family, the family heirloom knowledge, Lu Xun's uncle, the real head of the Lu family Lu Ji is proficient in easy learning, it is said that when he died a few years ago, he left a last word, saying that the world will be unified in sixty years. Wei Ba couldn't remember when the Three Kingdoms were unified, but the time should be about the same, so he felt that if this rumor was true, then Lu Ji was really a bit of a doorway. But he really didn't have a good impression of Lu Lan, and this scholar was a little bitter. The habits of the children of the family are very strong. It's hard to get close to, so when you talk to him, it's inevitable that there will be a little thorn.

Lu Lan was a little embarrassed. The Lu family is good at easy learning, but they want to ask Wei Ba to build siege machinery. This is enough to show that the so-called easy learning is not the best use. But it is useless to ask him to admit that it is easy to learn. But it is absolutely impossible. He didn't bother to bother with Wei Ba, so he arched his hand and said, "The general invites you to go." ”

Wei Ba stood up and smiled at Zhang Fen, who hadn't said a word since Lu Lan came in: "Brother Zhang." I'll come as soon as I go, and then we'll talk a little bit about what can be used in the world. ”

Zhang Fen nodded awkwardly, his face slightly red. Wei Ba patted the hem of his clothes and strode away. Lu Lan was furious, but she couldn't attack, so she had to stiffen her face and follow Wei Ba.

When he came to Lu Xun's big tent, Wei Ba didn't report in, he broke in as soon as he opened the tent door, and saw a woman in white talking to Lu Xun at a glance, and couldn't help but be stunned. Lu Xun is not like those exquisite generals, he never brings a maid by his side, and this woman does not look like a maid. He took a special look, the woman was not beautiful, but she was very delicate, but her eyes were very similar to Lu Xun, and she had a little hidden arrogance. Wei Ba noticed that what she was holding in her hand was the blueprint he had provided.

Seeing Wei Ba coming in, the woman hurriedly got up, but did not avoid the inner tent, but knelt behind Lu Xun and lowered her head.

"I'm from my sister." Lu Xun said lightly: "Ziyu, sit down, there are a few questions that I don't know very well, and I want to talk to you about them." ”

Wei Ba was very surprised, Lu Xun was in his forties, but this woman was only sixteen or seventeen years old, and he thought it was Lu Xun's daughter or something. He sat down, took the drawing, glanced at it, and said lightly: "If the general has anything unclear, please speak up." ”

"I know this is the siege vehicle you designed to attack Fancheng, but now I want to attack Xiangyang, the height of this siege vehicle is not enough, and Weishenme will not increase it higher?" Lu Xun spoke in a calm tone as usual, neither happy nor angry.

"If you increase it a little higher, the weight of the siege cart will be too large and it will be inconvenient to push."

"It's hard to push, just add some wheels." Lu Lan followed, just in time to pick up Wei Ba's words.

Wei Ba glanced at him and said unhurriedly: "Increasing the wheels will also increase the length of the cart, and it will not reduce the weight of each wheel." He paused for a moment, then continued: "And it will be counterproductive, and the efficiency will not increase but decrease." ”

"Since it is increased at the same time, weishenme will backfire?"

Wei Ba closed his mouth and refused to answer the question. Lu Lan was a little angry and was asking, the woman raised her head, signaled Lu Lan with her eyes not to be angry, and said in a harmonious voice: "When you say that you join the army, does you mean the ratio of the number of people in the cart to the number of soldiers on board?" ”

Wei Ba glanced at her in surprise, hesitated for a moment, and nodded.

The woman continued: "The army said that increasing the length of the cart will reduce the efficiency, does that mean that the efficiency will only be highest when the carriage is a square with equal sides?" ”

Wei Ba's doubts were even greater, what kind of demon was this, and how could he see the mystery at once. He designed this big car, it seems simple, anyone can imitate one, but it contains a large number of optimized designs, which are not obvious to ordinary people. You can imitate, but you can't go beyond it. This woman could see this, and he already felt that it was very difficult.

"Yes."

The woman's face was slightly red, but she looked at Wei Ba without giving in: "Can you please join the army and explain it in detail?" ”

Wei Ba frowned, turned his gaze to Lu Xun, and coughed: "General, I can help you build battle equipment, but I didn't say that I have the responsibility to teach it." I don't have much knowledge, it's my job to do that...... Doesn't seem like a good fit, right? ”

Lu Xun looked at him, turned around and exchanged a helpless look with the woman. The woman was a little disappointed, pursed her lips slightly, lowered her head, got up and bowed, and retreated into the back tent. Lu Xun rubbed his hands and said self-deprecatingly: "It's me who is rude, Ziyu doesn't want to say it." Let's not talk about it. So, this car, can not be heightened? ”

"It's not that it can't be heightened, but increasing the height will inevitably increase the volume, and it will also increase the number of carts, and there will be fewer soldiers who can really participate in the battle. In terms of the use of troops, some of the gains outweigh the losses. ”

"Then Ziyu can help me change it. To attack Xiangyang City, the height of this cart is really not enough to rely on. Lu Xun pushed the drawing in front of Wei Ba and patted it gently. Wei Ba took the drawings and thought about it for a while. A new sketch was drawn. Then he handed it to Lu Xun and said, "General, this is the most haode improvement I can make, if the general is not satisfied." I can't help it. ”

Lu Xun took the drawings. Took a look. I can't help but be amazed. Wei Ba changed the siege cart, which was originally the same width from top to bottom, to shrink layer by layer, and increased the height by one-third, enough for the people on the top floor to attack the head of Xiangyang City. However, the total volume has not changed, and the number of people pushing the cart does not need to increase, which can be described as killing two birds with one stone.

"Ziyu is really smart." Lu Xun praised it sincerely, put away the drawings, and said earnestly: "Ziyu, the battle equipment has been almost prepared, and I am ready to attack tomorrow." After you go back, you must ask General Wu and General Meng to guard Fancheng, and there must be no mistakes. ”

Wei Ba nodded, and there was a shallow disapproval at the corner of his mouth. When the Shu army attacked Fancheng, Lu Xun had been watching from the sidelines, and even when Sima Yi's troops were under the city, Lu Xun did not fulfill his obligations as an ally. Zhu Ran and the other three stayed on the boat, and they didn't even set foot on the north shore. Now that the Shu army has conquered Fancheng, the Wu army is still preparing war equipment in an orderly manner, which is obviously to let the Shu army be cannon fodder, Sima Yi and they are all outside Fancheng. In two days, more Wei troops will arrive, and the pressure on the Shu army will be very great at that time.

In the final analysis, Lu Xun still has bad intentions, and he is bent on using the Shu army as cannon fodder, and he is ready to leave at any time. However, things have come to this point, and it is not so easy for him to go. The time is ripe to attack Xiangyang, and if Lu Xun wants to leave without firing an arrow, it is estimated that Sun Quan will not agree. In contrast, the Shu army is different, their merits are enough, and the harvest has exceeded expectations, and they can leave at any time. Heavy losses of more than 20,000 Wei troops before and after, and the capture of a naval division in the air, for the Shu army with a total strength of only 30,000 people, this record is proud enough, no matter who can say irresponsible things.

"General rest assured, we will definitely do our best to support it." Wei Ba smiled slightly: "However, I want to ask the general a question, I don't know if it's okay?" ”

"Absolutely."

"General, do you really want to attack Xiangyang?" Wei Ba bit the word "really" very hard.

Lu Xun's eyebrows trembled: "What do you mean by this?" ”

"If the general really wants to fight Xiangyang, then there is no point in talking about it, if the general has no intention of taking Xiangyang at all, then there is no need for us to delay time here. With tens of thousands of troops, the daily expenses are staggering, and we really don't need to waste the blood and sweat of the people here in vain. ”

The corners of Lu Xun's eyes twitched, and he understood what Wei Ba meant: "What's the matter, your food is insufficient?" ”

Wei Ba nodded, looking a little embarrassed. Lu Lan couldn't help but purse his lips when he saw it, a flash of contempt flashed, and then he laughed gently.

"The general also knows that since the prime minister was stationed in Hanzhong the year before last, it has been more than two years now, and there have been major battles one after another, and the reserves over the years have been depleted. This time I came to Fancheng, fortunately, the war went smoothly, many prisoners were captured, and it also brought a lot of trouble, and our military food consumption rate increased sharply. Wei Ba smiled bitterly: "Don't hide it from the general, we have less than ten days of grain in stock, and there is not much grain to transport in Hanzhong, so we can only transfer it from Yong'an." The road is long, and we may run out of food at any time. ”

The smile on Lu Lan's face suddenly froze, and he only then understood what Wei Ba meant. This is not a discussion, this is blackmail. How could it be possible to capture Fancheng in ten days? This is clearly to ask Wu to pay their military rations, otherwise they will withdraw their troops.

Lu Lan was furious: "You want to blackmail us? ”

"Captain, what are you talking about?" Wei Ba said seriously: "I'm discussing with the general, how can I slander you?" I know that the general may not be able to be the master, so I have already told the news to Fei to join the army, presumably he has already been transferred to King Wu. I'm just trying to ask the general for his opinion. The reason why we have encountered this difficulty is also inseparable from your repeated delays. If you don't want to conquer Xiangyang, then let's simply withdraw our troops, so as not to consume money and food in vain. (To be continued.) For mobile phone users, please go to read. )
