The abacus is not complicated, but it took a little time to make those abacus, and before the second half of the night, the first abacus was ready. The honest carpenter looked at Wei Ba and rubbed his hands nervously: "Young master, can you still watch it?" ”

Wei Ba glanced at him and smiled: "You can see it, you are simply too beautiful." If you were given a little more time, would you plan to carve the whole frame with flowers? ”

"Hehe, the young master is right, it's true that there is not enough time, if it shouldn't be carved with flowers." The carpenter was really honest enough, he didn't hear what Wei Ba meant, and asked seriously: "Young master, the Wei family is a gate, and it stands to reason that fierce beasts such as lions, tigers, and bears should be carved to set off the might, but this abacus should be used more by Mr. Ledger, isn't it better to change flowers and plants?" Those poor sours like these the most. ”

Wei Ba almost didn't squirt out a mouthful of water, and Steward Chen's eyes widened: "Who did you hear say that the one who manages the accounts is poor and sour?" Shut your stinky mouth and get out! ”

"Ugh." When the carpenter saw that he had offended Steward Chen, he didn't even dare to let out a fart, and turned around to leave. Wei Ba stopped him, shook his abacus, and asked Steward Chen: "Steward Chen, according to your eyes, do you think it is necessary to carve these?" ”

"Of course you have to carve." Steward Chen was in a good mood, and although he had been busy all day, he was still in high spirits. Although this slave said it badly, there was some truth in it. Although it is a homely object, after all, it is still an ornament on the case, and it can be made more beautifully, which is of course haode. ”

Wei Ba was silent. He originally thought that the abacus was a tool, as long as it was strong and durable, and it was really unnecessary to spend time carving, but Steward Chen said this, he had his own reasons, and there was no need for him to change their views. He glanced at the cramped carpenter: "Thank you for your hard work, take a break, and eat a few pieces of meat, drink a bowl of wine, and sleep well." Hurry up tomorrow and make a dozen or so abacus for backup, is it too late? ”

Hearing that there was meat to eat and wine to drink, the carpenter's face finally showed a happy smile, and he nodded again and again, almost throwing off the wooden hairpin that bound his hair. It didn't take long for a chubby cook to report that the night meal was ready and ready to be eaten. Wei Ba nodded at Steward Chen, who stood up, clapped his hands, and said loudly, "Everyone, stop." ”

Seeing the cook come in, the craftsmen who were busy knew that the meal was about to be opened, and although their hands did not stop, their ears were pricked up, and they waited for the news of the meal. Today, the young man is in charge, there is wine and meat, but it is a rare feast, and they have been looking forward to it for a long time. As soon as they heard Steward Chen's words, everyone put down the work in their hands and stared at Steward Chen.

"The young master is gracious today, buys wine and meat, and gives you a tooth sacrifice. But I can put the ugly things in front of me. It is his kindness that the young master treats you favorably, but do not get carried away and forget your business. You can eat a little more rice, and you can eat two more pieces of meat, but the wine must be controlled, if anyone gets drunk and delays the work in the second half of the night, don't blame Lao Tzu for turning his face and not recognizing people, and beating you so much that you can't get up for half a month. Do you hear that? ”

After listening to Steward Chen's words, those people naturally remembered Steward Zhang, who had just been beaten by Wei Ba in the morning and couldn't get out of bed for half a month. The chief stewards around Madame can be beaten like this, let alone these lowly craftsmen. A few craftsmen who wanted to take the opportunity to drink and not get drunk swallowed their saliva, dispelled this thought, and agreed with a lot of words.

"Go, a quarter of an hour." Steward Chen waved his hand majestically, and everyone dispersed, and you pushed me to the kitchen.

Wei Ba looked at the craftsmen who were already salivating before they arrived in the kitchen, and didn't know what to say. The Wei family is good to the subordinates and craftsmen, and it can be known from the satisfaction of the three new blacksmiths, but even they rarely eat meat a few times a year, and for him who is tired of eating meat in later generations and always wants to have some vegetarian dishes to lose weight, this once again makes him feel the difference between the two shijie.

Steward Chen said respectfully: "Young master, you are tired for a day, go eat some too." Drink some wine and go to sleep, I'll keep an eye on it, and I won't miss anything. ”

"No need." Wei Ba waved his hand: "Although this matter is not complicated, it has a lot at stake. It's not that I can't trust you, but I have to watch from the sidelines to feel at ease. Even if I go to sleep now, I'm afraid I won't be able to sleep. He smiled and said, "Look at me now, can you sleep soundly?" ”

Steward Chen also laughed, fiddling with the abacus he had just sent, and said with emotion: "The young master is really a rare talent, and it is an idea in a blink of an eye. This abacus is much more convenient to use than the abacus, it looks very simple, but there are a lot of subtleties. ”

Wei Ba didn't care, he felt that there was nothing to be proud of in the abacus, and Steward Chen said this, it was nothing more than that he had gained his benefits today, so he thought of a way to pat his ass. Everyone loves to wear a top hat, but if Steward Chen is a flattering person, then it would be a bit reckless to bring him to Mrs. Zhang today.

"Especially this bead." Steward Chen didn't notice Wei Ba's unhappiness, and was still immersed in the abacus play. He clicked on the black bead that represented five in the upper column: "With the generation of five, there is one more beam, but four beads are reduced, not to mention the cost saving, and the number is clear at a glance, so there is no need to count it again." Tsk, that's amazing. ”

Wei Ba listened to Steward Chen's praise of the abacus in his own words, and then he realized that the abacus he thought was very simple was actually not simple. As Steward Chen said, a black bead above represents five, which is not only as simple as reducing four beads, but also making the numbers on each column clearer. I don't know who said that people can usually only take care of seven at most, within seven, you can see at a glance, more than seven, you have to count. If you don't use this black bead to represent five, then you need to use nine beads on each column, and it is difficult to distinguish the number of seven, eight or nine at a glance, with this black bead, the total number of beads is only more than five, and it is divided into two colors, which is relatively much easier.

There are ten in one generation and one hundred in the calculation, but there is no five in the generation, and this one generation five contains an advantage that is difficult for ordinary people to notice, he is used to it, and he does not notice it, but Manager Chen often deals with the calculation, and he found this difference at a glance.

Seeing the spirit in the subtleties, Wei Ba made a new discovery of the abacus for the first time. In his memory, the Han Dynasty abacus is to represent five with a black bead, and a white bead represents one, and there is no essential difference from the abacus in the future, which shows that the ancients were not stupid, and even to some extent smarter than the descendants, but unfortunately, because of the limited means of communication, there are many exquisite inventions that have not been passed on. For example, abacus, obviously the Han Dynasty already had an abacus, but in the Three Kingdoms era, there are still many people who have never even heard of it.

It seems that printing is really useful.

Wei Ba thought of more at once from this and the other. He suddenly felt that he had a lot to do.

Wei Ba was a jishu in his previous life, and he knew that details determine success or failure, not only qualitative, but also quantitative. After this life came, he has been entangled in his father Wei Yan's Meridian Valley scheme, so he has been thinking about how feasible this is. In his previous life, he also called Wei Yan aggrieved, and felt that Zhuge Liang was overly cautious if he didn't use his Meridian Valley plan, and even suspected of suppressing Wei Yan, but now that he thinks about it, even he thinks that this trick is better than gambling.

Many things look wonderful, but when you really do it, you will find that there are many difficulties in it, even difficulties that cannot be solved at all. For example, the current Meridian Valley conspiracy is not feasible at all in his opinion. If he were Zhuge Liang, he would not agree to this plan.

There are two ways in front of him: one is to persuade his father to give up Meridian Valley Jihua, so that at least there will be no conflict with Zhuge Liang, and it is possible to eliminate the hidden dangers designed by Zhuge Liang in advance in advance. But this doesn't seem to be very practical, listening to Daddy's tone, in his eyes, this Jihua is simply too perfect, Prime Minister Zhuge will definitely agree with his idea, maybe he will praise him for using soldiers like a god. Before touching the south wall, it is undoubtedly a fool's dream to persuade him to give up this jihua.

Then there is only one other way left: solve the key problems in the Meridian Valley Jihua, increase the feasibility of the Meridian Valley Jihua, and increase it to make Zhuge Liang feel that this Jihua is worth the risk and has a greater chance of success. So what is the key puzzle of Meridian Valley Jihua?

Grain.

With too much grain brought, the movement was slow, and the suddenness was lost, and when they came out of the valley, I am afraid that the Wei army would have been prepared to meet the head-on attack. The food was too small, the time left for the attack was too short, and it would not take more than a few days to rush back again, turning an important military operation into a ten-day tour, which was obviously not very feasible.

In order to turn this jihua into a reality, it is necessary to bring enough food to ensure that the army can have enough time to act, but not to delay the movement of the army and ensure suddenness.

This may seem like a dilemma, but it's not entirely impossible, and wouldn't it be perfect if you could build a machine that could transport more food and meet the demands of quick action?

Wei Ba had a flash of inspiration, and his eyes lit up.

"Young master, you ...... What are you thinking? Steward Chen's soft reminder interrupted Wei Ba's thoughts, Wei Ba was stunned for a moment, and smiled disguisedly: "What's wrong?" ”

"Is the young master thinking of anything new?" Steward Chen said a little nervously: "I didn't interrupt the young master's train of thought, did I?" ”

"No, no." Wei Ba scratched his head, only to find that those craftsmen had already returned from eating, and he seemed to have been distracted for a while, no wonder Steward Chen would interrupt him. However, he did make a discovery just now, and he seemed to have caught something, and was interrupted by Steward Chen, and that little idea disappeared again. ―――――― continue to ask for support and keep moving towards the top of the list!
