"Repair the bridge?" Li Chengqian wondered if there was something wrong with his ears.

After confirming it repeatedly, it was found that Tang Ping was really talking about repairing the bridge.

"Cousin, are you planning to build a bridge like the Big Stone Bridge?"

The big stone bridge that Li Chengqian said is actually the very famous Zhaozhou Bridge or Anji Bridge, located in Zhao County, Hebei Province, and built in the last years of the Sui Dynasty.

The span of 37 meters is built only with stone, so many people call it the Big Stone Bridge.

Tang Ping didn't know if the big stone bridge was Zhaozhou Bridge, or if Li Chengqian explained it to him.

In Li Chengqian's view, only a bridge with characteristics like Dashiqiao can become an Internet celebrity check-in point.

Tang Ping shook his head and said, "It can't be built that big, and the river is about ten meters long." ”

Chang'an has eight rivers around Chang'an, and there are indeed many rivers, large and small.

Li Chengqian also knew that he had passed over the river twice in the Special Administrative Region.

"Isn't there already a bridge over the river? Let's build another bridge, will anyone come and play? ”

"It's because there's a bridge that we have to build another one, and now the one that is there is normal for people to pass, and we'll build another one on the side to collect fees."

"Cousin, there are free people next to you who don't go, and there are people who come to go and charge a fee?" Of course, Li Chengqian knew that Tang Ping would not be untargeted.

But he couldn't figure out why anyone would pick a toll bridge to walk.

"Why don't we make a bet?"

"Don't bet!" Li Chengqian is not stupid, Tang Ping dares to say this, and he still dares to take it, isn't that a steady loser or a win?

Tang Ping couldn't fool this prince's cousin, so he could only say honestly: "Actually, what I want to build is not an ordinary bridge, but a glass bridge." ”

"Glass Bridge?" Li Chengqian's eyes widened: "That thing can build a bridge?" ”

Although glass is still a rarity now, it is also for ordinary people, and there are still a lot of glass products used by the second generation of emperors like Li Chengqian.

"It's not Datang's glass, I have to buy it from us."

Of course, Datang's current glass does not have such conditions, but modern ones can.

Speaking of many modern Internet celebrity check-in points, they are inseparable from one: glass bridges or glass plank roads.

With Datang's current steelmaking technology, there is no problem in making the steel frame below, and only the special glass bought by Tang Ping needs to be installed at that time.

After listening to Tang Ping's plan, Li Chengqian was still a little unsure: "So if we build a bridge with glass, someone is willing to spend money to walk on it?" ”

"Of course, there is!" Never underestimate human curiosity and the desire to challenge exciting projects.

Li Chengqian didn't hesitate much, nodded directly and said, "Okay, then how do we divide it?" ”

This cousin knows that although there are a lot of good things, they are not free.

His father had to give money when he took things from him.

It's just that in their opinion, what Tang Ping harvested was quite cheap, and it was completely sold as a cabbage price.

"You pay, I pay for the materials, I am responsible for the later maintenance, you are responsible for the on-site management, half of the booth is left for me, and everyone has five or five points of income!"

"Deal!"

Don't look at just building such a bridge, but the river beach was cleaned up in the early stage, the bridge foundation was built, and the materials were transported.

And business can't be on that bridge, right? I also have to build a place like a snack street for the stall vendors or something.

Tang Pingchu calculated these things, if they were to be carried out at the same time, at least thousands of laborers would be consumed.

In this era, although there is Tang Ping, there is still no crane, no forklift, no pile driver, at most a few steam locomotives can be used to pull materials, and only where there is a road, and the rest still have to be carried on the shoulder.

The consumption of manpower for this kind of project is very huge, and as for the remaining labor force in the special zone, Tang Ping will find another way.

If it really doesn't work, throw it over to the workshop area and tell them to expand a new workshop area by themselves.

The deal was reached, and Li Chengqian met Chang'an in a hurry, but a person was called in front of him in a moment.

"Li Da has seen the prince."

"No need to be polite, I want to ask, your father is Master Li Chun, right?" Li Chun in Li Chengqian's mouth is the designer of Zhaozhou Bridge.

"Back to the prince's words, the first father is Li Chun."

"How much did you learn your father's craft of building bridges?"

"It's a shame to say that my father's craftsmanship has only been comprehended by the lower officials seven or eight times out of ten."

"Okay, that's enough. We're going to build a glass bridge here. Li Chengqian turned the laptop around, and there was a photo of the location where the bridge was built.

This laptop is a birthday gift from Tang Ping, but it is one of his most important treasures, and he is usually guarded by four guards when he goes out.

"What bridge? Glass bridge? ”

Li Chengqian looked at Li Da's surprised expression and was very satisfied.

Why can't this prince be the only one who seems to be uninformed, right?

"You heard it right, it's the glass bridge!"

This Li Daren is in the Ministry of Industry, and the glass naturally knows, but that thing will break when the hard object is touched, how can it be used to build a bridge?

But since the prince said so, I think there is something special about it.

So Li Da stood aside obediently and didn't speak, waiting for Li Chengqian to continue.

Li Chengqian saw that Li Da was so eyeless, and it was not good to be a praiser, so he could only sigh helplessly and said: "The structure below is made of steel, and the bridge deck above is made of glass given by Pingguogong." ”

"Ping Guogong said that there is no problem with a piece of glass bearing thousands of catties, and in the end our requirement is to be able to see the river flowing under the bridge from the bridge deck. In addition, the bridge has to be built higher, at least seven or eight meters away from the river. ”

The more Li Da listened, the brighter his eyes became.

At the beginning, he said that Li Chun's craftsmanship, he understood seven or eight times out of ten, but in fact, it was all modest, which was a common problem of the ancients.

I can't come up and say that I'm much more fierce than my father, that's called unfilial piety.

If it is spread out, it will be difficult to mix in the Tang officialdom.

The real situation is that Li Chun said long before he passed away that his son has long been better than the blue.

The reason why he is not as famous as his father is because he does not have a work like Zhaozhou Bridge in his hands.

But this thing, it also depends on the opportunity, he does things for the imperial court, and if the imperial court doesn't build such a bridge, he can't spend money to build one himself.

Now the glass bridge in the mouth of the crown prince Li Chengqian is an extremely rare opportunity.

Just looking at the photos of the scene, coupled with Li Chengqian's narration, he has already begun to build such a glass bridge in his mind.

The more I think about it, the more excited I become, as long as each piece of Ping Guogong's glass can really withstand the power of thousands of catties, then I will create a unique and unique glass bridge.

"Prince, the lower officials are brave and want to borrow a pen and paper!"
