In addition to issuing a decree to let Han Qi and Ouyang Xiu protect Sun Ji, Renzong also prepared a series of actions, who was behind it, he already knew in his heart, Wang Deyong continued to toss, and others couldn't let them get better, at least among the factions, they couldn't be exposed, they couldn't be idle, they had to be tossed.

Renzong also knows that there is a limit to what he can do, and he will not even affect the stability of the entire political situation because of this incident, and even what he has discovered is not all, but if he doesn't do something, he will be sorry for the harm these people have done to him.

For the time being, Renzong has not yet figured out how to continue to protect Zhao Xin, but after he cleans up the Forbidden Palace and gives the Forbidden Palace a good environment, he is still ready to let Zhao Xin come back.

In the forbidden palace, at least there will be no such thing as the Baozhou mutiny, if you can instigate a rebellion in Bianliang, Tokyo, even the emperor Renzong can be pulled down, let alone a mere prince, for this, Renzong is quite confident.

In Bianliang, Tokyo, because of a telegram from Han Qi and Sun Ji, the undercurrent surged, and a series of orders began to be issued.

In Miaojiazhuang, Zhao Xin is thinking about the same thing, and he knows very well that what follows is a key point that will determine his next development.

He knew very well that maybe he couldn't stay in Miaojiazhuang, and he had to go to Bianliang, Tokyo, which was exactly what he didn't want to see the most, although he said that after going back, it would be quite safe, with Renzong's arrangement, coupled with his intelligence, some conspiracies and tricks could not threaten him, but he himself was also restricted.

No matter what, he is still a child, a hairy child who is only four or five years old, in the eyes of ordinary people, he is not used at all, but what he contains in his heart is enough to change the development of the entire Northern Song Dynasty and even the entire Chinese nation.

However, in terms of identity, he can't give up, the identity of the prince is still the identity of Renzong's only son, so he basically doesn't have to worry about any ceiling, or forcible seizure, etc., but for this identity, waste 10 years, or even 15 years, is this appropriate?

Ambivalence, so that Zhao Xin didn't know what to do, he could only have a little bit of a day and wait slowly.

Han Qi entered Baozhou with a large army, Miaojiazhuang regained calm, and the steamed bun business and soap business also reopened, but the number was not very large, on the contrary, it shrank a lot.

The population of the entire Baozhou has been removed by about 7 percent at once, and the rest are also poor and poor.

After the Baozhou Mutiny was resolved, there was no urgency for money, buns and soap, which could be exchanged for a certain amount of money, and the supporter card system and related research continued, which was already possible.

Among them, especially the cement, from the drawings given to Sun Ji Fortress, and with Sun Ji's hand, this fortress was handed over to Han Qi, Zhao Xin already knew that the Northern Song Dynasty high-level would definitely build a large number of fortresses.

The key materials for the construction of the fortress, red bricks and cement, red bricks are easy to do, from water cooling to air cooling, change the brick kiln, a little popularization, introduce a few key points, you can, the previous green brick kiln, it is very likely to be able to convert into a red brick kiln.

There is no problem on the bricks, the key is cement and steel, the former is necessary, the entire Northern Song Dynasty, and only Miaojiazhuang mastered, is the foundation of the construction of the fortress, without it, the fortress can not be built at all.

The steel of the latter is also very important, and even among the fortresses, the place with the largest cost, the output of the Northern Song Dynasty is not small, and it can be used in the small-scale construction of the fortresses, among which, as long as most of the support does not come into contact with water, it can be replaced by bamboo.

Although the later generations of moso bamboo, bamboo strips as the backbone of the project, known as the tofu slag project, but as long as it is not damp, rainy, dipped in water, such moso bamboo, flexibility and strength are enough.

In this era, the environment in the northwest is much better than in the 21st century, but it is also dry and rainy, which is not caused by the environment, this is caused by climatic conditions.

Compared with steel, bamboo is much cheaper, and it is easy to grow, bamboo is the fastest growing, a 60-foot tree, it may take 60 years, but for bamboo, there is a suitable environment, such as rain, it may only take 59 days, sometimes, a day can grow 1.5 meters, terrible.

In southern China, there are large areas of bamboo origin, in the past, these bamboos, did not have much effect, made into some handicrafts, can not be used at all, but once the large-scale construction of the fortress, it must be used in large quantities, which is equivalent to saving costs.

Steel, will also be studied in the future, whether it is the era of cold weapons, or the era of thermal weapons, steel is a very important system, even if Zhao Xin does not know much about them, but the small blast furnace made of earth can still do it.

These in the 21st century, are called high energy consumption, low output blast furnaces, in this era, in the 11th century AD, that is definitely advanced, with this, it will definitely keep the price of steel down.

The direction of research is more cement.

Cement is the only one that has no precedent, and although it has something in common with fired ceramics, it is a completely different and new business.

Fortunately, the technical content of cement is not high, and after the standard formula is available, and the cement is produced, the activity of researching new cement is actually stopped.

Under the premise that thermal weapons have not appeared and become popular, rashly studying new cement, that is useless, you can't smash it with a hammer, and you can't smash it with artillery, these are two concepts in the era of thermal weapons, but in the era of cold weapons, they can't be smashed, and if the strength is higher, it will overflow and be useless.

It is conceivable that in the future era of the fortress, or even the era of large-scale construction, the demand for cement is terrible.

Fortunately, as long as the formula is made and expanded, basically, there is no problem, with a higher blast furnace and more convenient grinding tools, Zhao Xin is even extravagant enough to use some meteorite to form the basic structure of the steel mill, and with a little bit of carving, the grinding tools are integrated.

In fact, this is the simplest mechanical conveyor, the crusher, which is iron or steel with higher hardness, used to crush lime and some cement clinker, so that it is more powdery and easier to use.

Under the premise that there is no power, no steam engine, and no electricity, water and manpower have become the basic choice.

The waterwheel was the simplest tool, and with the support of the carpenters, the construction of the waterwheel was no longer a problem, not only solving the problem of grinding and power, but also bringing good irrigation problems.

Miaojiazhuang was re-planned, some of the ponds were excavated, the waterwheel was driven by the flow of water, poured into these channels, itself only by the river, or very close to the place, can be watered, now, under the perfect ditch, completed the change of the entire Miaojiazhuang watering land, only this, Miaojiazhuang's future grain income, will turn over a few steps.

Some of the waterwheels were used to extract oil or grind flour, forming some workshops, but many more were used in cement workshops.

Of course, in order to avoid places where there is no water, the entire Central Plains is relatively rich in water resources, and water power can be used, but if it is placed in the northwest, it will not work.

If you want to popularize the fortress on a large scale, of course, you can't build cement factories and brick factories in the Central Plains, these are building materials, compared to food or something, it is much heavier, this era, there is no developed logistics in later generations, the best and most economical method is to build in the local area, and the transportation distance is best not to exceed 200 miles.

The research on cement has been carried out quite smoothly, the expansion of the blast furnace, the addition of hydraulic and manpower machines, the great saving of manpower, cement has gone from the initial small batch production to a medium degree of production, and a small cement kiln has appeared.

Cement already has the possibility of mass production, one by one technologies have been overcome, and a series of technologies to strengthen production and reduce energy consumption and consumption have emerged, all of which have been put into practice.

In the card system, the price of cement has also dropped rapidly, reaching the previous level of 3%, that is, the price of the original cement, compared with the present, is three times.

Lower cost, bring higher income, will also make the price of the fortress have a greater reduction, and the expected is not the same, in the end only one percent, the largest use of cement and bricks, is not the main body of the price of the fortress.

There is nothing to say about bricks, as soon as red bricks come out, they are cheaper than green bricks, but small-scale production and large-scale production are not as obvious as cement, after all, the materials used are clay, coal, these two things, in this era, quite cheap, as for labor, it is relatively high in Miaojiazhuang, and in other places, it can be ignored, the Northern Song Dynasty has natural workers, van army, and as long as necessary, it can be expanded to several times, or even more than ten times at any time.

Cement and bricks combined, the price of the fortress has dropped by 1 and a half, that is to say, the original cost of about 3000 guan, now reduced to about 2550 guan, it does not seem much, once the number of forts is enough on the premise, this saving amount is also a lot.

In fact, Zhao Xin is very clear that this has reached the limit of the reduction of the fortress, the reduction of raw materials, not so easy, if it continues to be reduced in the future, it is necessary to coordinate the above, how to make people maximize his role, divide the project into different breaks, and finally complete the collaboration, this aspect is done, and the price of the fortress can also be reduced.

Zhao Xin is not clear about this, he can only make some suggestions according to what he knows, and there is a certain amount of experience, so as to improve efficiency and reduce labor costs in the future, and it depends on those builders.
