Han Qi left satisfied in the afternoon, although he was a noble Zaifu, even if he returned to Beijing late at night, he would not be unable to enter the door, but such a privilege, even if it was Han Qi, it would be more troublesome to use, even if it was half an hour away from Bianliang and fast horses, they would go back in advance.

Han Qi left, Zhao Xin didn't go, that night, Zhao Xin actually stayed near the construction site, and it had already been decided to leave, and even last night, Zhao Xin also sent a letter to the concubine, he could imagine that the concubine received a new expression, but although the warmth was good, he couldn't indulge in it anymore.

Dingjun's development from scratch to the current level is not a critical stage of tackling fortifications, but it is inseparable from his control.

Although it is said that according to the set goal, there will not be many problems in the overall situation of the Ding Navy, but subtle problems will definitely appear, and the sooner we go back, the easier it will be to solve them; as far as industrialization is concerned, some subtle problems are enough to attract attention, which will affect efficiency at least and affect the direction of a certain product.

In fact, in the first three years of the development of the Ding Navy, unless it was a critical matter, Zhao Xin was not suitable to leave the Ding Navy.

The first three years were the three years of the fastest development of Ding Haijun, and the development has entered the formal, even if because of the pollution problem, some projects have not been involved in the field of harmony, reducing a lot of income, but only the current income is an astronomical amount.

You must know that in terms of pure Bianliang, the sales of Ding Haijun's various direct stores in Bianliang have a sales volume of more than 40 million yuan in half a year, and now, another step has been added, glass products can definitely be called luxury jewelry in the entire Northern Song Dynasty.

After the adjustment, the trend caused by it kept brewing, and at the beginning, it reached nearly 10 million sales, and it did not weaken much until after the Spring Festival.

This is different from Zhao Xin's estimate, he didn't expect that Bianliang and the radiation area, the purchasing power will be so strong, this is the most elite area of the Northern Song Dynasty, even in the Later Zhou and Later Han periods, there has not been much war, from the Later Han Dynasty to the current Renzong period, almost a hundred years of peace, and the capital, so that Bianliang is nearby, very prosperous.

This data, Zhao Xin is actually wrong in judgment, he calculated according to the Daimyo's Mansion, as well as the surrounding data, the Daimyo's Mansion, although it is also one of the four capitals of the Northern Song Dynasty, even during the Five Dynasties and Ten Kingdoms, it is still a place of war, after the establishment of the Northern Song Dynasty, it also has the experience of being breached, facing the threat of the Liao State, how many people and rich people can have.

But Bianliang is different, it is the capital, and Chengping is close to a hundred years, in this case, it is normal to accumulate enough wealth, plus Ding Haijun's various products, which are very suitable for ordinary people to use, so it produces such a large sales, and after the Spring Festival, it continues.

Under such a premise, combined with the various sales of previous products, it is expected that the sales volume in Bianliang may exceed 100 million yuan in the whole year.

100 million guan, this is a number that no one can think of before, if it is placed on the entire Bianliang people, the average person will spend 100 guan, which is a bit much, although some people, even spend 10,000 guan, 100,000 guan does not change their face, but most people spend a quantitative number.

However, the radiation of Bianliang is not only Bianliang itself, but the entire Bianliang periphery, which involves the entire water system.

This is involved, but tens of millions of people, and even some wealthy businessmen and officials, will also enter Bianliang with the change of official positions and some other moving processes.

Even if the gross profit is more than 30%, if it is really a real cost, it is as high as more than 80%, which is twice as terrible as the figure.

Bianliang may occupy an absolutely dominant position in the entire political and economic territory of the Northern Song Dynasty, even in terms of the radiation population, it also occupies one-tenth of the entire Northern Song Dynasty, but to say that the sales of Bianliang account for the vast majority of the entire Northern Song Dynasty, that is to say that it is a joke.

One-tenth of the population, even if the per capita consumption is high, equivalent to one or even two times that of ordinary places, it is possible, no matter how high, it is impossible.

The products produced by Ding Haijun are not exclusive to high-end luxury goods, if they are high-end, there is only one item of glass products, and in the future, when glass products are recovered from a certain amount of money, they will also quickly reduce their prices.

Compared with the more difficult and expensive high-end products, or the most basic products, it is easier to obtain greater profits, perhaps in thousands of quantities, to be able to achieve the original, the profit obtained from the sale of a product, but at the speed of industrial life, the production of thousands of products, is not more difficult than a fine product.

Even now, unless Zhao Xin uses the card system to manifest the product and produce it by hand in a normal way, even if it is a skilled master, after a long time of exploration and proficiency, it will take several days, or even ten days, to produce a fine product.

However, if such a skilled master carries out industrial production, as long as there is a certain amount of machine assistance and a certain production process, it is enough to produce thousands of finished products, which can be seen from the daimyo's blacksmith workshop.

Ironmaking and glass manufacturing may not be the same thing, but it is similar, and the large-scale glass industry is also one of the basic industries in daily life.

Because of the problem of vision, Zhao Xin will never consider the kind of profiteering industry, the profiteering industry will never be long-term, unless it is in materials and processes, otherwise, the simple secret recipe will never be able to be preserved for a long time.

The Venetians, for the protection of glass products, can be said to be extremely strict, in the era of no means of communication, no planes and satellites, find a remote desert island, all send death row prisoners to produce, so that Venice remained for hundreds of years, but in the end it was leaked, when the glass manufacturing process in Europe developed rapidly.

Keeping the secret recipe is a huge amount of wealth for a family, and a simple secret recipe is enough to support a family for hundreds of years, but for a country, it is an obstacle.

In the 21st century, finding a certain key is of course to be kept secret, but in this era, the whole world, even the original level of science and technology, has not developed to the height of the Northern Song Dynasty, let alone Ding Haijun has improved the scope of science and technology, with a relatively open attitude, to build the entire Ding Navy's scientific and technological foundation, and then, it is free development.

There was nothing to say all night, Zhao Xin's physical fitness, coupled with the tent in the wild, was not so simple, at least the sealing was quite good, and there was nothing to say all night.

The next morning, the sky was just dawn, the sun had not yet risen completely, taking advantage of the meager morning light, looking at the bridge that was already busy, this bridge from scratch, through in a short time, was only a part of this land, and on the other side of the morning light, in the plain covered by the mountains, there was a railway that pinned the expectations of the Ding Navy, in the intense construction.

As long as the basic construction and construction of the railway is completed, the huge transportation capacity and efficiency will definitely make the products of the entire Ding Navy obtain greater sales results.

In industrial society, supply and demand are the key, one hand raw materials, one hand sales, raw materials rise, bring a large increase in costs, and eventually reduce profits, or forced to increase prices, affecting sales share.

In the middle, the problem of transportation is very critical, many industrial areas in later generations, mostly built in places with developed transportation, some poor places, even if the labor cost is very low, can not attract large-scale factories, the core lies in the traffic problem.

The traffic conditions of the Northern Song Dynasty have been much better than most of the dynasties, the Northern Song Dynasty attaches the most importance to the Beijing-Hangzhou Grand Canal, with the help of the water system of the Beijing-Hangzhou Grand Canal, through China's most important water systems, the Yangtze River, the Yellow River, the Huai River, the Haihe River, almost the most important water system of the entire Central Plains, are included, and the water transport is exceptionally developed.

Even the most traditional water transportation, as long as the scale is up, to ensure the round-trip transportation, can also ensure that the freight is reduced to a very low level, this transportation, support the production and sales of the entire Ding Navy.

With the increasing size of the Ding Navy, the method of river transportation is somewhat inappropriate.

Water transport at any time, is relatively cheap, but really cheap, that is by sea, sea transport can be transported around the clock, as long as it is not a frozen port, and the carrying capacity of sea transport, as long as the technical standards, how big a ship can be built, how big a ship can be used to transport.

Under the premise of the same tonnage, the larger the ship, the lower the transportation cost, in addition to the labor cost, there are a series of transportation costs.

River transportation is different, the carrying capacity of the big river is strong, the carrying capacity of the small river is small, at the same time, there is the difference between the dry period and the wet period, and even the north is frozen, which has a small volume of the Ding Navy, the impact is not very great, but when the Ding Navy continues to develop, especially when it controls the daily consumption of the entire Northern Song Dynasty, the materials needed are astronomical.

This is the result that Zhao Xin spent 40 days to go to Bianliang, and now, it has been successfully completed, of course he should retire.

Zhao Xin left Bianliang with Han Qi, and his fleet still stayed in Bianliang, in fact, this fleet has gone back and forth between Bianliang and Hongze Lake twice in the past 40 days.

Zhao Xin's pomp and circumstance in Bianliang this time was huge, but the materials and commodities needed by the Ding Navy were massive, and a huge fleet of ships could not just lie in Bianliang like this, they shouldered a huge task, and they needed to be loaded with all kinds of goods to and from the river.

Now, the last transport, 2 days ago, completed the unloading, just waiting in Bianliang, no, Zhao Xin came out, and the fleet also came out, at present, it is on the Bianhe River.

Zhao Xin did not leave directly on the ship, since he has seen such a bridge, then take a look at it, the railway from Yingtian to Bianliang is very short, but it is very critical, not only a stage for the high-level display of the Northern Song Dynasty, but also a key throat, once completed, from Yingtianfu to Bianliang, the freight capacity will be increased many times.

Even to a certain extent, it will also promote the generation of passenger transport in advance, feudal society, for household registration management is relatively strong, but short-distance movement, there is no problem, some in the peasants, leave the land, to do odd jobs in the city, there are a lot.

As long as the railway is repaired and the price is not very high, some farmers who are far away in Yingtianfu can even go to work in the Bianliang, originally, it is only about forty or fifty miles away from people to come, now 300 miles away, it is also half a day's time, which is no problem for farmers, as long as they can afford the starting fare.

Because of these considerations, Zhao Xin did not leave directly, but inspected along the road.

In fact, there is no problem with the railway, with the experience of the Ding Navy, the construction is no longer a problem, and the key node is always the bridge.

Of these bridges, the one that I passed through earlier is just a small place, and the real key points are those of the big bridges.

Bridges of more than 10 meters are becoming more difficult to construct, especially for longer, 20-meter, and 30-meter bridges, the difficulty of construction will increase significantly.

The largest checkpoint restricting such a railway is actually a bridge between Yingtianfu and Bianliang, which is the bridge with the largest span.

This bridge, the distance of this simple river surface, is more than 80 meters, and the overall bridge, at least a bridge of more than 180 meters, can be said to be the biggest difficulty in construction.

The length of the bridge, increase several times, bring the construction period and the amount of work, the improvement is also very high, on the river, the construction of the bridge, has entered the end, as long as the cement is dried up, you can lay the rails, complete the final construction.

However, longer bridges, such as those above 150 meters, have not even been built yet, and the 60-meter-long river surface, to a certain extent, is quite a difficult thing.

Zhao Xin heard about this key bridge, and wanted to come and visit it before, but with the appearance of Han Qi, he had to choose the closest bridge to Bianliang, and he was not able to see this most critical project, but now, after coming freely, this bridge is inevitable.

The 300-mile-long railway, if it is divided into more sections, the construction speed can obviously go up a grade, the key problem, on such a bridge, this bridge, may be the entire railway construction, the longest time-consuming, the most technically difficult bridge, not only there are 4 cranes here, the entire Ding Navy, the construction of railways and bridges, the most outstanding technicians, are also here.

Almost the vast majority of the technical force is placed on this bridge, and the construction of this bridge is still slow, because it is not a single-hole arch bridge, but a three-hole arch bridge.
