Five hundred guan is a big number for Wei Zheng, who has two sleeves and a clean breeze, and how much money does he have in a year? He also has to feed his family, so he can't afford even a reduction of one-tenth.

To be poor is to be poor, and there is no other reason.

However, for a rich man like Lu Guogong, 500 guan is not a sky-high price. Even if he is distressed, he will never give up because of this, and even the reason that it will be significantly cheaper in a few days is not enough to make him postpone the time to buy a car.

"That's it, I want one!"

Looking at King Han with a smile on his face, Cheng Zhijie secretly gritted his teeth and said: "Please also ask the king to let people make it as soon as possible, if you can go out in the spring, it would be the best." ”

Hearing this, he immediately shook his head, and Li Yuanjia smiled: "Hehe, this is a bit difficult. The craftsmen who made me the carriage are now busy with the things His Majesty has explained, and it is estimated that it will take another month or two to free up their hands, if the carriage is to be ready...... Well, why will it have to wait until May. ”

Since the beginning of winter, the tipping workshop has almost been a one-day off.

It's too cold.

Without enough warm clothing, especially gloves, the craftsmen could not work at all, and even if they did barely work, they had frozen holes in their hands. So in the end, in order to ensure that the task assigned by the king can be completed next year, Wang Pu had to order the entire line to be stopped, and wait for the weather to be warmer.

In other words, most of the more than this month has been wasted.

So once the weather warms up, the carpenters have to go all out to resume the production of the rollover. Especially in March next year, it is a critical moment for them to complete their task, and it must not be disturbed! It must wait until after March, when the carpenters that Li Shimin gave to his younger brother can build 300 overturned carriages a month, and Chen Mu and other carpenters belonging to the Han Wangfu can pull out their hands and build a new four-wheeled carriage for Cheng Zhijie.

It's just that Cheng Zhijie is a little dissatisfied with this response.

Just when he wanted to say something good, so that Li Yuanjia could give him an advance, the other party suddenly smiled and said: "In addition, there is another advantage to postponing it to May, that is, the cost of the carriage can be reduced to four hundred; If Lu Guogong is willing to wait until August or September, it can be reduced to at least 300 per car...... Well, even less, it's not impossible! ”

Hearing his words, Cheng Zhijie's eyes widened instantly, and the doubts in his heart blurted out: "Four hundred? Three hundred? How is it so little?! ”

"Hehe, it's very simple, because after making a unified arrangement, everyone's efficiency has improved!"

His eyes narrowed slightly, and Li Yuanjia chuckled.

"Efficiency? What does this mean? ”

“…… To put it simply, it is the speed at which things are done, which can be accelerated in some ways. ”

"How?"

“……”

Looking at Lu Guogong, who was confused and full of curiosity at the same time, Li Yuanjia opened his mouth, and he really didn't know how to explain to him - if it was King Wei in front of him, he would be very happy to explain, because Li Yuanjia knew that Li Tai would definitely understand what he was talking about, but the one in front of him ......

Tell him ten times, will he understand?

Fortunately, Li Yuanjia immediately thought of a way, blinked his eyes and shrugged his shoulders and said: "In fact, it is the same method as overturning, which can speed up and reduce the cost at the same time." But again, like a rollover, it has to be mass-produced to be useful, if only one is made for you...... It's slow and expensive, no way. ”

As soon as he said that it was the same as overturning, Cheng Zhijie immediately understood.

King Han took over His Majesty's task, and made a military order to build 300 overturned cars in a month, Cheng Zhijie naturally knew about it, and he also knew that this master had to use a special method to do it. It's just that what the specific method is, Lu Guogong is confused.

It may be easier for a fifty-year-old man to get him to accept the assembly line, but it is too difficult to get him to learn mathematics and understand how to make arrangements.

King Han was not interested in explaining, but Lu Guogong's interest was aroused all of a sudden, and he squinted his eyes and asked, "King, the old minister dares to ask, can your method be used in other places?" Like ironmaking or something? ”

"Ironmaking? That's not going to work. ”

After being stunned for a moment, Li Yuanjia smiled and said, "This method can only be used in ...... Well, it's used to make things, and it has to be something a little bit more complicated. For example, siege vehicles to be used in the army and the like, which are more effective, and there are ......"

After a moment's hesitation, he didn't continue.

Although Li Yuanjia wants to say that it can also be used to build weapons and arrows, and it can greatly reduce the cost, but unfortunately, he doesn't know much about ancient weapon manufacturing, and he doesn't know whether the assembly line operation method can be used on it, so it's better to keep his mouth shut and say nothing.

"That's ......"

After listening to his words, Cheng Zhijie nodded thoughtfully, and an intriguing look flashed in his eyes.

Just as he was pondering, Li Yuanjia beckoned directly to Han Lucheng: "Lu Guogong's tea is cold, replace it with a hot one!" ”

"Huh? No need, haha. ”

Awakened by his voice, Cheng Zhijie laughed and said: "The king, this old minister of tea really can't enjoy it, it's uncomfortable to drink it!" ”

“……”

Suppressing the urge to roll his eyes, Li Yuanjia just twitched the corners of his mouth and didn't say anything.

"Alas! Why is it so difficult to promote tea this year? ”

Looking at Lu Guogong, who was faintly flashing with contempt in his eyes and was obviously disapproving of the tea, Li Yuanjia could only sigh secretly, and missed his eldest nephew very much at this time.

Look at Li Tai, who is good at mathematics, understands things quickly, and even likes to drink brewed tea, he is simply the most perfect "progressive" in this era, and he is also the person Li Yuanjia hopes to be in contact with often.

Look at the ...... in front of you

To be honest, Li Yuanjia really doesn't want to see him after a long time of contact.

Originally, it was quite difficult to let a modern person get along with an ancient, it was difficult to find any common language, if he met an older person like Cheng Zhijie again, Li Yuanjia really felt that there was nothing to talk about.

But just when he felt bored, Cheng Zhijie suddenly asked: "King, I don't know which method you said, can the old minister learn it?" ”

"Huh? Lu Guogong, do you want to learn? ”

Listening to Cheng Zhijie's words, Li Yuanjia's eyes suddenly widened.

"Yes, the old minister wants to learn, I don't know if it's okay?"

"This ......"

After being stunned for a moment, Li Yuanjia's expression gradually became strange.

"If it's inconvenient, forget it."

"Hehe, nothing inconvenient."

Seeing that the other party had the intention of retreating, Li Yuanjia suddenly became anxious, and quickly shook his head desperately and said: "Lu Guogong wants to learn, that is the honor of this king, naturally there is no problem!" It's just that if you want to learn that method, you must first learn a set of books called "mathematics", I'm afraid that Lu Guogong won't be able to stick to it......"
