At Li's residence, Yang Zuan had a good time drinking with Li. When he was full, he returned to the county government with the drawings of the water mill.

At this time of slack farming, it is not troublesome to recruit and distribute service households. Yang Zuo did not break his promise. He soon recruited and distributed 5000 servicemen from the county, led by yamen servicemen and scribes, and began to renovate the road from Dingzhou village to Huxian county.

Although the enlisted servicemen don't have to pay wages, the food expenses need Li forget to worry about.

Li forgets to worry. Naturally, he doesn't mean to save this copper money. He provides delicious and delicious food for the servicemen three times a day. Every time he eats meat, the servicemen who come to repair the road are grateful for the generosity of Huxian uncle, and they worked hard to repair the road.

Twenty miles is not long.

Five thousand servicemen were directly divided into ten groups. Under the command of craftsmen sent by the county government, they started construction from ten places at the same time. Each group of 500 people was responsible for construction, and the distance was only one kilometer.

Rammed earth is the most labor-intensive way for Datang to build roads.

It requires countless strong labor to constantly lift the heavy wooden piles, lift them high and then fall, repeatedly smash them into the subgrade, tamp the pavement, and then roll them back and forth with a stone roller. Finally, put firewood on the shelf and burn the road again, so that there will be no grass and insects, which is solid and durable.

According to Yang Zuan and the craftsmen sent by Hu county to direct the road construction, it will take three or four months to complete the construction of this 20 mile long road.

A serviceman's service time in a year is 20 days. Yang Zui estimated that he would have to recruit four or five rounds of servicemen to meet Li forgetful's needs for road construction.

But Li forgot to let them build roads like this.

He only asked the servicemen to fill the road and then use a stone roller to compact it. They also used four-wheel carriages to pull carts of crushed stones from the quarry and spread them on it.

In this regard, the craftsman in charge of road construction from Huxian county government couldn't help but say, "Huxian uncle, the soil is not compacted, but the speed is fast. But I'm afraid the road will be destroyed as soon as it rains. Even if these stones are paved, the carriages will sink in as soon as they are rolled over. It's impossible to build the road like this."

Li forgot to worry, shook his head and smiled: "it doesn't matter. At last, I'm going to lay a layer of mirage mud on the road. Isn't that right?"

"What? Spreading mirage mud on the ground? This... It's too expensive?" the craftsman naturally knows what mirage mud is, but he never thought of spreading such precious mirage mud on the road. In his opinion, isn't this the black sheep of the family?

The artisans secretly make complaints about themselves. In the city of Changan, they all said that the Huxian Bo was a black sheep. What is the difference between paving with mirage mud and paving money on the road?

But anyway, the money is Li forgetful. Since he is willing to throw the money on this road, the craftsman naturally doesn't say much.

Besides, he was also curious about what it would be like to spread the mirage mud on the road.

Make complaints about make complaints about the reliable situation.

How to burn the "volcanic ash instead of cement" has long been handed over to the Ministry of work and the general for supervision, but more than half a year later, the output has not increased at all. Isn't it that lime and clay are calcined in a kiln? What a simple thing. It took so long. This cement hasn't been popularized in Datang. It's still a rare thing.

Li forgot to worry about it. Although lime is not a rare thing in Datang, its output is not high.

After all, lime can only be obtained by craftsmen mining limestone and calcining it, which is not comparable to the efficiency of large-scale industrial production in later generations.

That is, his Huxian uncle has a big face now, and Yan Liben mediates for him in prison. Otherwise, even if he spends money, he can't get so much cement to pave the road.

In order to build this 20 mile long road, Li forgot to worry about grinding hard bubbles and got 20000 stone mirage mud from the Ministry of work and the general supervisor.

Twenty thousand stones, that is, only two thousand tons, but it cost Li forgetful ten thousand dollars, equivalent to five copper dollars per ton of cement.

In this regard, Li forget worry is very unhappy, but also helpless.

Cement in later generations is only four or five hundred yuan a ton, but these five copper coins are equivalent to 20000 yuan in later generations. It's really a sky high price.

The cost of food and materials for building roads for other servicemen added up to almost another 10000 yuan. In a short 20 Mile Road, when the servicemen didn't need to pay, Li forgot to worry and threw out more than 20000 copper coins.

It's also a pity that he didn't need money, otherwise he really didn't dare to build a concrete road in such a reckless way.

This price is really not cheap. It will cost about 300000 a kilometer to build a concrete road and a four meter wide Village Road in future generations.

Li forgot to worry about building this ten kilometer road, which cost 20000 yuan, which is equivalent to 80 million yuan in future generations! The cost of eight million yuan for one kilometer is sky high!

With sufficient financial support and the hard work of the servicemen, an unprecedented cement road appeared in Datang in just 20 days.

Huxian Uncle Li forgot his worries and "lost his family" again. The news soon spread all over Huxian, even into Chang'an City and Li Er's ears.

People have different reactions to this.

There are those who shake their heads and sigh, those who admire and look forward to.

When the new road is completed, not only Dingzhou village has caused a sensation, but also the farmers in Huxian county and the surrounding villages have flocked to see this "loser road".

Yes, the 20 mile road from Huxian county to Dingzhou village is now called "loser road" by Huxian people.

It's incredible to spend 20000 yuan to build a ten mile long road. It's not a loser. What's a loser?

However, the people were stunned when they walked on this "loser road".

Is this the way?

It looks like a road paved with a whole gray white slate, which is really beyond the imagination of the Tang people.

Although Li Qieyou has already handed over the cement to the chaotang, it is rarely seen among the people, let alone used to pave the road. People have never seen the cement paved road, and they think it will look like this.

An old man couldn't believe it. He smashed several times on the cement road with his crutch. Not only did there not appear any concave holes, but his palms were numb.

"This, this is the immortal method! This road is clearly paved with a whole stone slab."

"Taigong, this is the mirage mud road. Do you know the mirage mud? It was made by the Huxian uncle. After the mirage mud dried up, it was so hard, not afraid of water and fire, and it was magical." a person familiar with the matter explained to the old man.

When a good man heard the speech, he immediately ran to fetch a bucket of water and poured it on the road.

Under the gaze of the crowd, I saw that the water could not seep into the road at all, but flowed to both sides of the road and into the roadside drainage ditch. The residual water stains on the cement pavement soon evaporated under the sunlight, leaving no watermark.

On the concrete pavement, there are four grooves embedded with wooden tracks.

This is the running track designed for the carriage, called the track.

Of course, the track was not invented by Li Qieyou. The track had appeared as early as the Qin Dynasty. This kind of wooden track will clamp the wheels of the carriage inside and build it smoothly. The carriage runs very fast.

The track is similar to the rutting marks on the official road of the Tang Dynasty, but it is smoother and smoother.

When the people of Huxian county were surprised by this "loser road", there was another team of people who set out from Chang'an City and came straight to this road
