The setting sun and the crimson Western Ocean shrouded the entire Ding Navy in a feeling of light and night.

In such a light, the scenery of the entire Ding Navy looks different, countless high-rise buildings look so different in the night, and as the night comes, the time to get off work is also up, and the workers in blue heavy overalls begin to walk the streets, and the streets are immediately lively.

With the alternation of night and day, the street lights are lit up one by one, night and day, in ancient society, those were two worlds, and most of the things that could be done during the day could not be done at night.

However, this point was broken in the Ding Navy, and the three-shift night shift system was the first to be proposed in the Northern Song Dynasty, of course, the farthest only lasted until the time of the child.

It's not that Zhao Xin doesn't want people to stop working, the basic conditions can't be met, in the Northern Song Dynasty, there are no vitamins and the like for the time being, and the general public has night blindness.

Night blindness is a very niche disease in later generations, and even if it is suffered, it can be cured quickly, as long as vitamin A supplementation is sufficient.

Foods rich in vitamin A, mainly liver, fish, seafood, these foods are meat, in the Northern Song Dynasty, meat is not easy to obtain, and the price is high, this is not ordinary people to eat, plants can be supplemented with vitamin A, that is, carrots as the head, this kind of products, at present, I am afraid that only green tea, is in the Northern Song Dynasty more, but unfortunately this is also ordinary people have no way to use it for a long time.

Because of this, in ancient times, there were many people with night blindness among the people, and in addition to the fact that lighting was not widespread, ordinary farmers, at night, could not see anything, and did not arrange many activities at night.

This is also the reason why night raids are a very important strategy in ancient warfare, and if they are used properly, using a group of elites to carry out night raids will produce great results.

It's just that the limitations are very great, only the most elite under his command, and those who don't have night blindness are definitely elites, those who are trained as the most elite soldiers, fed with good wine and meat, and trained much higher than ordinary soldiers every day, so that the elite can take on the heavy responsibility of night attacks.

In Ding Haijun, with the advent of kerosene lamps, kerosene lamps made of glass can be brighter, not as bright as day, but similar, even if there is night blindness, it will be much better, but it is not suitable for long-term work.

For the time being, the longest working time is 9 hours, and it will generally stay for about 3 hours, and only in the future, the population quality of the entire Ding Navy will gradually change after it has been greatly improved.

If you want to supplement various vitamins, you must adjust the dietary structure, Ding Haijun has done a very good job in this regard, but you can't force these people to eat well.

At present, under the premise that the high-yield crop corn in South America is not found, the feed industry cannot be opened, although the animal husbandry can be carried out, but the cost is not small, the cost of meat is still not low, plus the freight, the price is still relatively high.

The first people who came to Ding Haijun, under the continuous high treatment, have settled their families, and the quality of life is also improving, in this case, they will also improve their lives, but they are also quite modest, and later joined Ding Haijun, most of them have basic living standards.

For the working people at the bottom, it is a very good thing to be able to eat a full stomach, and it is too luxurious to eat meat every day and every meal.

Zhao Xin also knows this very well, perhaps, he can add a lunch to the workers in the factory, increase the intake of some aspects, but he can't force the others to do the same, which will take time to change slowly.

Perhaps, in the future, when cheap meat appears around the Ding Navy, and the quantity is very large, it will be able to change all this.

Port No. 1, the largest port of the Ding Navy, is extremely busy all day long, but before, his busyness simply refers to the daytime, even if the port of the Ding Navy is considered a deep-water port, in the dark night, it is also a very dangerous thing to enter the port, after all, the control of the sail for the ship is not as accurate as the power of the ship, and it is very dangerous to enter the port in the dark.

But now, there is a difference, a clear height of about 100 meters of lighthouse, erected on a height of about 50 meters, after several layers of processing, there are multiple light sources, and can be reflected by the glass mirror, the light source is concentrated together, the formation of spotlights, can provide enough guidance for the ships entering the port, so that this port, truly day and night integration.

At sea, especially in the familiar waterways, as long as the visibility is not very low, it is not so dangerous to sail at night.

This transit, no matter what it is, as long as it enters the port, it must waste a day, sometimes, only one or two hours away, for safety, it must also turn to Haizhou, so for safety, after all, in the open sea at night, around the Ding Navy, there is no way to anchor.

Now, with the addition of lighthouses, most of the time, you can successfully enter the port, and in terms of pure time, you can generally save a day's time, which is also a big help for Ding Haijun.

At this time, just after nightfall, a huge ship is entering the port, the flag on this ship, not the flag of the Ding Navy, but the flag of the Wu family, a big merchant in the south of the Yangtze River, this 12,000 material ship, even in the Northern Song Dynasty is a relatively large ship, because of the loading capacity of the Chinese sailing ship, it can transport more than 20,000 materials.

However, it seems that there are more things on this ship, and even the cabin cannot fit in it, and the deck is all placed, round and long, and obviously, all of them are giant logs.

At present, Zhao Xin began to frantically expand the shipbuilding capacity of the Ding Navy, simply the docks under construction, as many as 50, this is not a small dock like the original experimental ship, all of them are more than 40,000 large docks, once the technology of the sailing ship is explored to a certain extent, it will inevitably expand the scale, large-scale explosion of productivity.

The benefits of industrialization are not only the use of new things, but also change and innovation.

This is also what Zhao Xin has been looking forward to, for a certain detail, for a little bit of saving, to change the process, instead of inheriting the master's inheritance, according to the master's inheritance of the golden law, this seems, some mistakes, but in fact, it is the best, as long as there is such a spirit, maybe just a little bit of improvement, the future will be different.

The foundation of the maritime industry is shipbuilding, and in the era of sail warships, the most important shipbuilding material is not steel, but wood, to be precise, wood that has been processed and is more suitable for shipbuilding.

Ding Haijun already has a huge steel plant with an annual output of 2 million tons, relying on this, it seems that a few hundred tons of ironclad ships should not be a problem, but Zhao Xin did not rashly light up this technology line.

The reason is very simple, a ship, not only the quality of itself, so that the steel corrosion, this is a long subject, how to maintain and clean, is always a difficult process, compared to wood, iron in the seawater, more corrosive, and more difficult to handle.

If it is simply the anti-corrosion of steel, this is acceptable, and it is not necessarily impossible to specialize in a coating that is compatible with steel and use it for a long time, but another reason is the key.

Power is also a reason, more suitable for the ship, is steam power, strong steam propulsion, he for the structure of the hull, put forward an important requirement, when the horsepower keeps increasing, has been higher than the strength of the wooden ship itself, which is also the foundation of the later steamship in the world.

The steam engine, this requires a lot of things, in Ding Haijun's, research on it has been carried out, but the progress is not too big, it is expected to be developed, at least a few years, for the time being, just accumulation.

Similarly, in this era, even the Northern Song Dynasty, which had the most developed navigation in the world, still used Chinese-style sailboats, which had an average speed of only about 4 knots, and the new sailboats were enough.

Even if Zhao Xin was anxious about the ocean, and wanted to open the era of navigation for the Northern Song Dynasty, he had to consider the limits of his bearing, and rashly entered a higher realm, not to mention the advanced in later generations, when there was no mature steam engine, he entered the era of ironclad ships, which was a nightmare.

Rushing into imperfect technology may be able to accumulate experience, but it is more of a waste, countless verifications in later generations, too many things are wasted and spent on exploration, but on the contrary, followers will live better, and they can catch up in small steps.

Now don't say it's Ding Haijun, even if it's the Northern Song Dynasty, it's at the top of the world, but with Zhao Xin's experience, he won't take a detour, and he will take the most suitable path.

Timber for shipbuilding, in the Ding Navy, is definitely impossible, the Ding Navy area is not small, there are also some mountains, of course, will also produce wood, but most of the tree species near the seaside are not suitable for processing ships of wood, and even if there is, Zhao Xin will not be able to dry up and fish, and cut down the trees of the entire Ding Navy.

Even the construction of large-scale factories must maintain the ecological environment, and it is not his choice to cut down the mountains for a certain project.

In the era of underdeveloped science and technology, especially the cultivation and planting of various trees, it is important to maintain the original ecology.

Otherwise, if a geological disaster is caused by indiscriminate deforestation, it will be all over.

Geological disasters, even if they are placed in sparsely populated places, are not small, not to mention in the Ding Navy, which is densely populated and industrially developed, and the same geological disasters have greater destructive power and greater losses here.

These losses, not to mention a little bit of wood, even if it is ten times or hundreds of times the wood, cannot be replaced.

Shipbuilding has always been the focus of Zhao Xin, even before, when the Ding Navy had just opened and there was no shipbuilding factory, Zhao Xin had spared no effort to import all kinds of wood suitable for ship production.

In the entire shipping network of the Ding Navy, wood transportation is the top priority, and at the beginning, the surplus ship materials of the Jiangnan Shipyard were purchased at a high price.

All kinds of materials, even wood, have a fixed treatment process, in the traditional Chinese treatment, through a certain environment, let the ship materials dry, become usable, and long-term storage, can also reduce some of the internal stress, to achieve a suitable degree.

Ding Haijun pursues fast in everything, and this fast is not a purposeless and indiscriminate pursuit, but on the basis of rules and quality.

Natural drying, need to stand for a long time, drying room appeared, natural curved wood, which is on the ship, is the bottleneck, is a restriction, but some static devices, as well as bent tools also came into being, as long as it is placed for a period of time, release the stress in it.

In short, in the Ding Navy, the preparation of ship materials also takes time, but compared with the southern shipyard, the placement of ten or twenty years is still much faster.

Ding Navy fleet, shouldering too many tasks, at the time of turning, if not to transport raw materials back, often will be loaded with wood, relative to the uncertainty of other raw material origins, wood is available everywhere, as long as there are mountains, there are wood, in the middle of the selection suitable for shipbuilding, this should be a more universal material, but also a way to reduce transportation costs.

However, the current fleet size of the Ding Navy cannot support such a huge purchase of timber, a 10,000-material sailing ship, aside from some other bits and pieces, requires at least 9,000 timber, and if you add waste, it even exceeds 10,000 materials.

According to the calculation of the 70 docks currently under construction of the Ding Navy, even if they are all sailing ships with 10,000 materials, the total amount is as high as 700,000 materials, which is still half a month's demand.

The industrialized and streamlined Ding Navy produced ships at a rate more than seven or eight times faster than the skilled shipyards in Jiangnan, which also brought a huge number.

Two ships a month, and if the efficiency is further improved in the future, it will be increased to three, or even more, under the premise of the huge number of docks of the Ding Navy, the amount of wood consumed every month is an astronomical amount.

Even according to the current data, at least more than 10 million materials a year, which is a heavy pressure for shipping, and even if it is rich in timber, there is a huge pressure, the ship material is not just a casual wood, you need some special wood, more suitable for shipbuilding wood, most of these wood need a certain number of years to be able to grow, and in the deep mountains.

Under the premise that there is no way to greatly increase its own transportation capacity, it is a good choice to choose outsourcing, which not only saves transportation capacity, but also reduces operating costs.

This merchant surnamed Wu is one of them, in fact, after Zhao Xin announced the new regulations, all the big families in the entire Jiangnan were attracted, even some maritime merchants were no exception.
