Pork is already very common in Yangzhou, in addition to some old stubborn, even the wealthy families, there are many people who have accepted pork, and these "main dishes" are naturally indispensable at the New Year's Day banquet.

At the New Year's Day banquet in the fifth year of Jian'an, in addition to pork, there was also one more main dish - cement.

Not to let everyone eat cement, but to show the effect of "cement"!

This kind of magical "soil" that dries quickly after adding water and stirring quickly attracted the attention of the civil and military forces of the General's Mansion.

The generals thought that in the future, when they set up camp and set up camp, they could quickly build a "small Wu Fort", while Wenchen thought of renovating houses and adding city walls......

The brick buildings of the Eastern Han Dynasty still use yellow mud as a binder, and the solidity and durability are not high.

The city walls, including the Great Wall of Qin, are mainly rammed earth walls, and there are very few sections with rammed earth as walls.

Normally, after the Song Dynasty, lime mortar mixed with lime sand appeared as a binder, and in the Ming Dynasty, lime mortar began to be mixed with glutinous rice juice as a binder to build the Ming Great Wall.

With cement, it means that the city wall can also be changed to a masonry structure, and there is also a military aspect, which can directly transport cement casting bunkers!

"Lord, I don't know how much this 'cement' is worth?" Lu Kang was the first to ask.

Lao Lu is also worried, if he doesn't ask the price first, the Ministry of Industry, the Ministry of Civil Affairs, and the Privy Council will have to open their mouths, and the Ministry of Household will not be able to bear it!

"The manufacturing is very simple, after three years of secrecy, it can almost be opened to private operations, and counterfeiting is not cheap now, but ...... There are many raw materials, and if the mining scale is large, the cost is low. Bai Tu said.

Lu Kang breathed a sigh of relief when he heard this, and then looked at Lu Su with a smile.

Although Bai Tu did not say the specific cost, it ...... To put it very clearly, to "mine".

Well, that is...... I want the Ministry of Civil Affairs to mine it myself!

When the time comes, if it is enough, let's go to the Ministry of Civil Affairs!

In particular, the Ministry of Civil Affairs itself is a large consumer of consumables, and now you have to mine it yourself, and see who else you can go to to chase the debt!

"This year is the fifth year of Jian'an, and we will strive for the second half of the year to ensure that the front line can use cement, and in the seventh year of Jian'an, we can start to use cement to build the main city wall, and in the ninth year of Jian'an, we can use cement to build roads in the city, as well as the main road from the port to nearby cities, and in the twelfth year of Jian'an, we can start to use cement to build official roads." Bai Tu said his vision for the future.

As soon as I heard that in a few years, all official roads would be repaired with this artifact, and many people understood the cost of this thing - it was definitely not high, but no one cared about it before, so the raw material mining efforts were not large!

Of course, now everyone has also adapted to Bai Tu's statement.

The so-called 12 years of Jian'an, to start to use cement to repair the official road, it is just the "beginning", not to mention, the main official road will be completed after a few years, and it does not mean that the previous roads in the city, the main road from the port to the nearby city, have been completed in the 12th year of Jian'an.

It just refers to the 12th year of Jian'an, and the grain production of cement is enough for everyone to use together......

"Lord, didn't you say before that the road raises the people's wealth and the road increases the people's strength? Since this cement can be obtained so easily, why not mobilize the labor of various counties, and at the same time add the raw material mining of cement to the inspection project of the ministry, we are not afraid of heavy burdens! The head of a ministry said to Bai Tu patting his chest.

The other ministries around him, especially the chief officials such as the Taishou County Commander in various places, looked at him more and more unkindly.

Are you still human?

You're not afraid of heavy burdens......

You came to inspect and inspect, and the burden is heavy!

Of course, there are many people who are in a hurry to build roads, and after seeing the effect of cement, especially the raw materials and products of the workshop need to be transported over long distances, and the family that contracts the mines, I hope to pave the road as soon as possible.

"It's good for everyone to have this heart, but now all counties and townships have their own burdens, and hard work can benefit the people, but manpower can't be easily overdrawn." Instead, the white map acts as a brake.

There is no way, the price of everything on the right track is that a large amount of squeezed out manpower has been arranged clearly.

It is no longer possible to easily concentrate a large amount of manpower and focus on a certain project as before.

At the same time, this is also the real advantage of the General's Mansion!

Cao Cao thought it was okay to imitate Bai Tu's armament and wealth?

Even if Bai Tu shared with him the blast furnace ironmaking and steel filling method, the Prime Minister's Mansion had no foundation in other aspects, and how many nails could be made by blindly squeezing the people's power?

The Ministry of Industry and the control bureaucrats in various places, including the salt works and the like, have recently taken down a lot of spies from the north and even Jingchu.

While Bai Tu instructed all places to pay attention to security, he was actually not in a hurry......

The benefits of salt and iron, in the final analysis, are just collecting taxes from the people in disguise, and in the Central Plains under Cao Cao's governance, the people's power has been overdrawn, and he is given a means of collecting taxes, and the changes are also limited.

As for asking Cao Cao to squeeze out manpower to repair the waterways at this time? It's better to just let him surrender......

For the General's Palace, the constraint to development is coal, or population and manpower.

The real gas engine can be further improved, and if it is used for civilian use, it will further squeeze out the industrialized population and make up for the lack of coal, otherwise it will rely on charcoal alone...... Bai Tu cut down the Xing'an Mountains, and it may not be industrialized enough.

There are also high-yielding crops, which can also crowd out the population.

In addition, the only way to alleviate the shortage of population and manpower is to liberate the productive forces of other regions.

For example, if Jingzhou is conquered, the total population can be doubled, and as long as the Yangzhou model is also started in Jingzhou, two or three years later, there will also be a large amount of manpower, which can overflow from agriculture and can be invested in the construction of industrialization.

As long as the progress bar of industrialization can be pushed up, Bai Tu doesn't know how to lose, whether it is agricultural civilization, nomadic civilization, fishing and hunting civilization, no matter how many horses, no matter how fierce the blood, it is impossible to harden the industrial civilization.

"It's another twelfth year of Jian'an......" Lu Lingqi wrinkled her nose on the side.

Because it was a New Year's Day banquet, not a New Year's Day party, Lu Lingqi sat next to Bai Tu, and no one would say anything.

The reason why Lu Lingqi sighed like this is because many of the plans of the General's Mansion seem to be based on twelve or thirteen years as an important node.

For example, the graduation tide of the first batch of students who went from the township to the county school and really cultivated from an early age; The promotion of pig and poultry breeding and the use of chemical fertilizers will include the per capita consumption of vegetables, fruits and meat into the assessment of local officials; The plan covers the whole of Yangzhou, and the second phase of the large-scale water conservancy project has been completed; Iron and steel production is basically stable, the rotation of military service is fully realized, and 12 large ports will be built in 12 years......

"yes, what a coincidence!" Bai Tu also sighed.

The twelfth year of Jian'an in history is also an important year, this year Cao Cao completely recovered Hebei, subdued the Wuhuan who tried to go south, Gongsun Kang presented Yuan Shang's head to Cao Cao to show his submission, the old white face in Jingzhou was also in this year, he was sick and could not be governed, Cai's collusion with the Nanjun family was autocratic, and the eldest son Liu Qi was not allowed to visit.

It was also the year before the curtain was raised on the great war that really decided the pattern of the Three Kingdoms......
