The birth of cement can be said to break the restriction that stone can only be used by grinding and molding, so it immediately attracted the attention of many people.

In particular, the officials along the road paved by Wang Dazhui were very interested in such a magical new thing.

If the floor is paved with stone such as slate, then the amount of slate required is undoubtedly very large.

However, at this time in the Tang Dynasty, there was no mechanical polishing, so the production of stone slabs could only rely on a little primitive tools from craftsmen to chisel and polish them.

In this way, the production cost is high, and the output is not guaranteed at all, and it already requires a large number of stonemasons to work day and night for use in places such as the Imperial Palace, so it is impossible to generalize.

Why did ancient construction projects often last for several years or even more than ten years? It is because of the materials used that the processing and transportation are very inconvenient.

The flooring of the palace is no easier than the production of gold, which is quarried from the mountains and polished by a large number of workers piece by piece.

The production of cement is much easier than the grinding and forming of the whole stone, and the more important thing is that the cement is convenient to transport, so there is no need to worry about damage during transportation. As long as you do a good job of moisture prevention, you can do it.

If you want to polish a slate of equal size, you must be careful in this process, otherwise any mistake may lead to the loss of previous efforts and the slate will break.

Of course, there are also fired stone bricks, just like the floor tiles of later generations, which are not polished, but its production process is also very complicated, and not only is the cost high, but the transportation is also a very difficult thing.

Therefore, these things can only be used in places like the palace, and other people can't afford them at all.

Seeing the great use of cement in paving roads, these officials were very interested, just as a pervert saw a seductive beauty; It's like a drunkard seeing a mellow and delicious wine; It's like a wealth lover seeing glittering gold and silver treasures.

It can be said that there is an endless stream of people who come to the cement factory to find Wang Dazhui.

Everyone wanted Wang Da Hammer to provide cement to repair the road where they were.

The cement pavement is not only smooth, but also not afraid of rain and general rolling, for these people who are fed up with dirt roads, it is simply a rare treasure.

Thanks to the concrete road, the carriage travels no faster than before, and there are fewer bumps, so there is no longer a dusty sunny day and muddy rainy days.

Who doesn't want something so good? So as long as everyone knew the news, they all came to Wang Dazhu.

However, due to the current process problems, the output of cement is really limited, and it is impossible to meet the requirements of so many people.

However, this is not difficult for our protagonist Wang Da Hammer, since everyone wants it, and the number is limited, in order to compete fairly, Wang Da Hammer decided to let them bid.

For convenience, Wang Dazhui gathered all the people who asked for the door and announced that he wanted to unify the bidding.

The word "bidding" proposed by Wang Dazhui is very unfamiliar, and everyone doesn't understand what's going on, but after some explanation, everyone quickly understands what bidding is.

Bidding and auctions have a lot in common, but there are also differences, and the bidding requirements are more stringent, especially for buyers. So, in their view, bidding is an alternative way of auctioning.

We don't have any opinions on this, after all, for the time being, cement is available here, others will not produce it at all, and the output of cement is limited.

The reason why Wang Dazhui used the bidding method was that there were too many people who came to him to buy cement, and everyone's identities were not ordinary, so it was really difficult to choose.

If there is no relatively fair and reasonable way to trade, it is difficult to satisfy everyone, after all, no matter which one of them is not something that Wang Dazhui's current identity can easily offend.

"In order for everyone to be able to obtain the right to purchase cement in a fair and just way, we chose to bid, and I hope you will understand us more." Before the bidding began, Wang Dazhui stood on the stage and said.

"Understand, understand, Wang Xiannan should hurry up and start bidding! We've been waiting here long enough for cement. ”

"Yes! We're all waiting to get back! ”

"Let's get started!"

As soon as Wang Dazhu's words fell, the representatives of various places below urged one after another.

"Okay, since everyone understands, then I won't delay everyone's time, but please abide by our agreement and don't have any dissatisfaction after the bidding is over." Wang Dazhui said with a smile.

"Don't worry, Wang Xiannan, you said it so clearly, and we all feel that this distribution method is very fair, and even if you can't get it, we won't resent you." The man sitting in the front row immediately took a stand.

In fact, Wang Dazhui had already explained to them all the matters of the bidding before, and also told them that even if they couldn't buy cement immediately this time, they didn't have to worry, because there would definitely be more and more production in the future.

The participants in this bidding are basically divided according to administrative regions.

In the first year of Zhenguan (627), Taizong of Tang Dynasty was a province and a county, and the whole country was divided into ten provinces according to the situation of mountains and rivers, namely Guannei Road, Henan Road, Hedong Road, Hebei Province, Shannan Road, Longyou Road, Huainan Road, Jiangnan Road, Jiannan Road and Lingnan Road.

Guannei: Roughly equivalent to the central and northern parts of present-day Shaanxi, Longdong of Gansu and Hetao of Inner Mongolia.

Henan: It roughly corresponds to the area south of the Yellow River in present-day Henan and Shandong provinces, and north of the Huai River in Jiangsu and Anhui provinces.

Hedong: Roughly equivalent to the area between the whole province of present-day Shanxi and the inner and outer Great Wall in the northwest of Hebei.

Hebei: Roughly equivalent to the south of the Great Wall of Hebei today. Most of the area north of the Yellow River in Henan and Shandong provinces.

Shannan: Roughly equivalent to the eastern part of present-day Sichuan, the southern part of Shaanxi and Gansu, the southwestern part of Henan, and the western part of Hubei.

Longyou: Roughly equivalent to the area west of Longshan and Liupan Mountains in present-day Gansu, east of Qinghai Lake in Qinghai Province and eastern Xinjiang.

Huainan: Roughly equivalent to the area south of Huaishui in present-day Anhui, Jiangsu, and Henan provinces, and north of the Yangtze River in eastern Hubei.

Jiangnan: Roughly equivalent to the four provinces of Zhejiang, Fujian, Jiangxi, and Hunan, the south of the Yangtze River in Jiangsu and Anhui, Hubei, part of Jiangnan in Sichuan, and the northeast of Guizhou.

Jiannan: Roughly equivalent to the central part of present-day Sichuan and the northern tip of Yunnan.

Lingnan: Roughly equivalent to the area of present-day Guangdong, Guangxi and northeastern Vietnam.

Basically, everyone in each place sent people to participate in the bidding, and the competition between them was fierce.
