I am the cook, but I am Li Er's son-in-law

Lu Yigong looked at the little girl in front of him.

This kind of old-fashioned speaking attitude is very similar to the store owner, so she should be the store owner's younger sister?

but.
Didn't I ask Her Royal Highness and the others for advice? Why did the store's sister jump out?
"Grandpa, may I ask you a question?" Seeing that Lu Yigong didn't reply, Yin Lulu urged her to ask again.

Lu Yigong woke up startled, nodded: "Well, yes, it's me."

Yin Lulu beckoned to him: "Come on, come on, grandpa, come and sit down here, my brother. I've prepared the answer to your question."

Lu Yigong nodded, and sat down at Li Lizhi's table with some reservations.

"Grandpa, what you want to ask is about road construction?" Before Lu Yigong could speak, Yin Lulu asked first.

Lu Yigong nodded.

Before he could utter a single word, Yin Lulu continued, "In road construction, quality is very important."

"Especially in the field section, the cost of maintenance is higher, so when building, you can add some bamboo strips to it"

In some cement roads that require high quality, steel bars need to be filled - of course, in this era, such things cannot be cast, or in other words, even if they can be cast, the cost is not affordable by Datang .

Bamboo strips may be a little inferior.

In the standards of later generations, it is a tofu dregs project.

But... this is the best standard that can be achieved at the moment.

Yin Lulu suppressed her small face and talked about the things to pay attention to when building the road. Yin Lulu couldn't remember everything in one night, and Li Lizhi and the others hurriedly added.

Fortunately, Ji Wen kindly provided the pen, ink, paper and inkstone, and Lu Yigong was able to write down one by one.

Yin Xuan didn't know much about these small details.

But there is one point, one point, that can avoid detours.

Wait until Yin Lulu finished asking dryly.

Lu Yigong looked at the two pieces of paper and sighed secretly. Sure enough, he was right to come here to inquire. If he were to grope for these things, he would waste a lot of time and cost.

But... these are not what he wants most.

Looking at Yin Lulu's immature face, Lu Yigong hesitated for a moment, but still couldn't help asking: "I still have some questions."

"If the court wants to earn some copper coins through the road, what should it do?"

As he said that, he coughed and replied solemnly: "Your Majesty is benevolent and righteous, he doesn't want to follow the example of Emperor Sui Yang and do those things that anger people."

"That's why your Majesty asked the ministers to avoid corvees as much as possible when building roads."

"If that's the case, I don't know what the little lady can do?"

Yin Lulu tilted her head, making a very tangled look. Her acting skills were immature, but Lu Yigong didn't see it. After thinking for a while, Yin Lulu said, "Well, I am right, Brother Cong, I am know some ways."

Lu Yigong's eyes lit up.

"Grandpa, can you try an advertisement?" Yin Lulu said innocently.

advertise?

Widely advertising?
Lu Yigong narrowed his eyes and looked at Yin Lulu with some doubts: "Please ask my lady to clarify."

"Grandpa wants to build a road from where to where?" Yin Lulu asked.

Lu Yigong replied, "From Chang'an to Luoyang."

Yin Lulu stretched out her hand and gestured for the length: "That should be a long distance, then Grandpa might as well set up a few wooden stakes by the side of the road and stick big posters on them."

"say"

"Write something like 'Which is the best food in the world, Chang'an Huaizhen is looking for Tongfu', and then draw some food patterns, then people passing the whole road will know that there is a Tongfu restaurant in Chang'an. "

"That's advertising."

After speaking, Yin Lulu paused, she was tired after talking for a long time, took a sip of the tea brought by Li Lizhi, and she continued, "Grandpa can sell advertisements."

"For example, a billboard is erected every one mile, and then a unit of [-] miles is used. Whoever buys it at that time can use the billboards of the [-] miles to print their own advertisements."

Yin Lulu raised her hand and made a gesture.

"And the billboards have two sides. People from Chang'an to Luoyang can sell to people in Luoyang, and people from Luoyang to Chang'an can sell to people in Chang'an."

Lu Yigong's eyes lit up, he raised his pen and quickly wrote down the method.

Yin Lulu waited for him to finish memorizing, then continued.

Like road tolls, service areas
For Lu Yigong, these things undoubtedly opened the door to a new world - he never expected that a road, in addition to tariffs, could generate so much revenue.

By the time Yin Lulu finished speaking, all the guests at noon had left.

Lu Yigong carefully collected these pieces of paper, and then bowed to Yin Lulu and the princesses: "Thank you for your guidance, ladies."

Yin Lulu waved her hand: "It's okay, as long as I can help Grandpa."

As she spoke, she paused for a moment, and said the last sentence that Yin Xuan explained: "If Grandpa has all the work ready, don't forget to leave some advertising space for my house when you want to hold a business promotion meeting."

Lu Yi respectfully nodded: "Definitely."

After having a meal at Tongfu Restaurant, Lu Yigong got into the carriage going home, thought for a while, and changed his route halfway, going to Wei Wangfu first.

That day he remembered that King Wei seemed to have nothing to say.

Enter Wei Wangfu.

Li Tai quickly met with Lu Yigong: "Lu Shilang is very handsome, it seems that my eldest sister was moved by talking?"

Lu Yigong nodded: "Yes, thank you His Royal Highness Wei Wang for your guidance, otherwise I don't know how long I will be confused."

Li Tai was overjoyed, and said urgently: "That's good, the store must be extraordinary if you think about it, I've been thinking about it at the mansion for the past few days."

"Gu can help with road construction."

Lu Yigong was a little surprised.

What can His Royal Highness Wei Wang do to help himself?Could it be that His Royal Highness King Wei is going to pay for the advertisement?

Li Tai paused, then continued: "The construction of roads has nothing to do with geography. When Mr. Taught me, he said that some geology is not suitable for road construction."

"Besides, road construction is for people's livelihood, not just a single road."

"It will not only connect Chang'an and Luoyang, but also cities of all sizes between Chang'an and Luoyang."

"Just right, the geography learned by the students will come in handy. I wonder if Lu Shilang is willing to let the students help to test the theory."

Li Tai stood up and bowed to Lu Yigong.

When Lu Yigong approached him for the first time, he wanted to say this, but he didn't.
