The joy on the faces of Lu Min and the others suddenly froze. If you can't get close, then how can you destroy the trebuchet? This time the fire attack disrupted the formation intercepted by the Xianbei people, and next time Dou Gui was prepared, it was indeed unlikely that there would be any chance left. Just look at Dou Gui's second reaction, although he is inexperienced, he is smart enough. In Xia Yu's words, the same method will not work the second time.

Xia Yu's thick eyebrows tightened, and he couldn't hide his worry: "Think about it, is there any better way?" ”

Lu Min was silent in thought, and Xia Yu turned his hopeful gaze to Liu Xiu. Liu Xiu, who had been staring at the battlefield in the distance, suddenly laughed: "Come and don't be rude, let's also let them taste the power of the stone thrower." ”

Xia Yu was puzzled: "What did you say?" ”

"We also build stone throwers." The corners of Liu Xiu's mouth twitched, and he said easily: "Use a stone thrower to throw the oil tank out, no one needs to throw it, so let's see how he copes." ”

Xia Yu's eyes lit up, and then he frowned: "The way is good, but ...... We don't build a stone thrower. ”

Liu Xiu smiled: "Please gather the craftsmen of the baggage camp, and let's discuss it together, it should be able to be built soon, and it can be better than them." It's just that...... There may not be enough wood. ”

"Wood?" Xia Yu rolled his eyes, and then smiled: "I have a way, demolish the house and use the beams!" ”

Night fell, the outside of the city that had been fighting for a day had calmed down, brewing the next fierce battle, the city and the outside of the city did not dare to take it lightly, although the soldiers behind Feng Yuan had been transferred back to the city to rest, but there were still a considerable number of open and dark posts outside the city, so as not to be stolen by the other party, and there were always people on the city wall who monitored every move of the Xianbei camp opposite.

Zhang He stayed outside the city for a day, and had a few small-scale contacts with the Split Tempest, although the Xianbei people who dismounted and fought on foot were very brave, but they did not take advantage of the Euphorbia at all, threw down dozens of corpses, and retreated in a gray manner. Zhang He didn't have a good time, but he was full of energy at the moment, and he got together with Liu Xiu, Lu Min and others to make suggestions.

More than a dozen craftsmen sat together, watching Liu Xiu explain the principle of the stone thrower with a simple model that he had just made, their eyes were shining one by one, and they were full of energy, and they were not unhappy at all because of staying up late. The first is that this little gentleman not only speaks clearly, but also often stops to ask their opinions, and respects them very much, and the second is that Mr. Lu has just instructed his beautiful daughter-in-law to prepare a sumptuous supper for them, except for the lack of wine, the rest is enough, which makes the craftsmen get double satisfaction in spirit and material, and the spirit of nature is excited.

"That's the general appearance, the basic size is also these, please do a few model tests first, and then we will start to make the first stone thrower, so that those Xianbei people can taste our benefits." Liu Xiu said, glancing at Lu Min, Lu Min understood, and coughed: "Everyone has worked hard these days, and when you repel the Xianbei people, I will ask for credit for you." ”

"Don't worry, sir, we will do our best." The craftsmen were happy, and the first wrinkled old craftsman patted his shriveled chest with his thick knuckle hand and said loudly: "The two gentlemen go to rest, we will work harder, and we will be able to make the model by tomorrow morning at the latest." ”

"Yes, the two gentlemen should rest and go, these crafts will be handed over to us." Another middle-aged craftsman also said loudly in a thick voice.

"Then I'll bother you." Lu Min politely arched his hand, forcibly endured the ** that wanted to yawn, turned around and went out of the door, only to open his mouth without grace, yawn bigly, and then patted his mouth with his sleeve, smacked his mouth, turned his eyes a little dry, patted the railing and said: "Deran, how can you be a stone thrower?" ”

Liu Xiu was silent for a moment, and then asked rhetorically, "Senior brother, why don't you know such a simple thing?" ”

"Is it easy?" Lu Min glanced at him and asked rhetorically.

"I think it's very simple, isn't it just a lever? I understood it at a glance. Liu Xiu frowned slightly, took a bowl of porridge from Lan Lan's hand and took a sip, "And I told those craftsmen that they also understood at once, there are a few places where we feel that there may be difficulties, and their ideas are even better than we estimated." As long as you have seen a stone thrower, it should not be difficult to make it, right? ”

Mao Yan handed over a hot hand towel for Lu Min to wipe his face, then stuffed a bowl of hot porridge into his hand, glanced at Liu Xiu, and said angrily: "You think everyone is as smart as you, and you will do it after a glance." Your senior brother is a scholar, how can you usually have time to take care of these skills? ”

Liu Xiu didn't say anything, he understood the reason. A scholar like Lu Min doesn't care about these skills, even if he has seen them, he won't pay attention to them, unless he uses them in the future, maybe he can recall them, if he can't use them, maybe he will never mention them again, and of course it is impossible to leave words. Those craftsmen may be familiar with the details of production, but they are illiterate, and it is impossible for them to leave words and pictures, so they can only pass it on by word of mouth, and those who have done it themselves may not have the opportunity to take the apprentice to do it, if the apprentice does not have the opportunity to do it himself, and then pass it on to his own apprentice, he may not be able to remember this thing.

This is probably the reason why so many of China's exquisite skills have been lost.

This matter should end with me. Liu Xiu drank weakness while secretly making up his mind.

"Deran, it's the fault of those of us who read." Lu Min suddenly said: "Don't talk about these skills, it's the "Donghu Zhi" you wrote, if you changed the previous me, I'm afraid I won't take a look." But this time, we were able to gain the upper hand, relying on "Dong Hu Zhi" and these hundred skills. I wonder if we're ignoring something that seems mundane, but is actually important. ”

Liu Xiu glanced at Lu Min in surprise, and Lu Min also happened to look over, his eyes were very serious, and there was no element of laughter. Liu Xiu smiled silently: "Senior brother, what you said is not bad at all. When I brought the book to the teacher, he threw it aside like garbage, and I don't think he would look at it again. ”

Lu Min was a little embarrassed, and was silent for a moment before saying, "Deran, my father is that temper, don't blame him." ”

Liu Xiu shook his head, "How could I blame the teacher." He thought for a moment and said, "They say that a lot of Han Chinese have run away to the grasslands, and I don't think that's a good thing." Dou Gui has brought us so much trouble, who knows what kind of strange people there are among those people. We're going to have to find a way to try to attract these people back. ”

"It's easier said than done." Lu Min sighed: "Don't say anything else, just talk about the Dou family, do you think they are willing to run to the grassland to be Xianbei dogs?" They are also forced to have no way out. And those party members, you don't know how many people were killed by the party twice, the last time the party was killed, I happened to accompany my father in Luoyang, and I saw those people being dragged across the streets of Luoyang, and killed one by one in Luoyang City, it was really bloody and miserable. ”

Liu Xiu suddenly remembered a question: "Is the teacher in the list of party members?" ”

Lu Min shook his head: "He doesn't like those party members, he thinks they are acting against the world, pretending to be loud, and they are not really scholars." Lu Min thought for a while, and then said: "Actually, many people don't approve of the party, you are like Mr. Cai Bojiao, Yang Boxian Yang, they are not party members. ”

Liu Xiu frowned, it turns out that these celebrities are not party members, so it seems that there are some problems with the quality of those so-called party members, not that he thinks they are all high-minded celebrities, maybe he was fooled by public opinion again.
