It is only three days away from Bianliang, but this distance is not so easy to walk, the cold air in the first few days, and heavy snowfall, so that the Bianhe River is a little frozen, even if it is relatively thin, but after a few days, it still accumulates a considerable thickness, even if the fleet is huge, it is impossible to go to the ice.

Fortunately, Zhao Xin had already prepared, among the many ships, there was an icebreaker, the icebreaker, to put it bluntly, wrapped the bow with special steel, using the kinetic energy of the ship to break the ice.

Later, China sent icebreakers and research ships to Antarctica, and even the icebergs in Antarctica could be broken, and the ice on the Bianhe River, of course, was not a problem, but it was the technology of the 21st century, and it was supported by radar and satellites.

In this era, there is not even the basic power, the steam engine has begun to be studied, but there is no rubber, and there is not much progress in polymer composite materials.

The same is true of icebreakers, made of the strongest steel in the navy, made of solid bows, plus boats, propelled by 20 men, to crash into those ices.

This icebreaker can be said to be very simple, and to put it bluntly, if it is in the coldest season of Bianliang, under the premise that the ice is very thick, these icebreakers are simply not able to compare with the thick ice.

Fortunately, this winter, the sorghum is not too cold.

Winter, for any era, is a place of slaughter, especially feudal society, even more so, in winter, it is not particularly convenient for anyone to travel.

The reason why Bianliang has developed transportation is because of various waterways, as well as waterways connecting the five major rivers and the Beijing-Hangzhou Grand Canal.

However, these water transportation, in winter, will be cut off, and the various wharves that used to be extremely busy in Bianliang have now become extremely cold, and there is not even a person.

Today, however, changes have taken place on the Bianhe River.

Both sides of the Bianhe River, because of the relationship between transportation and the irrigation of the Bianhe River to the surrounding area, have always been the core area of the Northern Song Dynasty, and the surrounding population is large, and those ports, even if there are no jobs, there are also a large number of warehouses, which need to be guarded when winter comes.

However, today, there are at least 10 special boats on the Bianhe River, which is surrounded by soldiers, and the frozen river prohibits the movement of all boats, but these boats can walk freely on the river.

At first, those who were in the harbor thought that these ships were just trapped here, and they didn't know how thick the ice of the Bianhe River was, so they rushed to go.

But later, it turned out that it was not the case at all, these ships were not merchant ships, nor were they common ships on the Bianhe River, they were clearly icebreakers.

The ship is not big, at most it is two or three meters wide, on the Bianhe River, it can not be regarded as a big ship at all, this is the most important waterway in the Northern Song Dynasty, after several expansions, this channel can already dock more than 1000 stone of large ships, the surrounding commercial exchanges are also endless, these small boats, some like car ships, the speed is very fast, but not suitable for carrying goods.

The icebreaker is indeed a vehicle and ship modification, only the vehicle and ship can have enough speed, an icebreaking bow, the whole is made of steel, at least more than 1.5 tons, which is not too big under the premise, the specific gravity of steel is more than seven points, one cubic meter is as high as 7 tons, 1.5 tons, and even 0.2 cubic meters, it must be used intensively, forming a bow made of pure steel.

20 people, in the cabin, frantically treading, the hard bow of the boat, gave him confidence, not to mention the ice, even if there were stones in front of them, they dared to crash over.

The sharp bow, under the speed, rushed to the ice in front, Zhao Xin has also seen some icebreakers, he is working at Peking University, when the Snow Dragon was dispatched, he also had classmates to follow, and he has been sent off 4 times, I don't know the specific layout of the Snow Dragon, but the shape, he is still clear.

Perhaps, he doesn't know what certain shapes are used for, and he won't know how many scientists' efforts are concentrated in these shapes, so he just needs to use them.

It's like the huge difference between the Northern Song Dynasty and the 21st century, but just some things, as long as you explain it clearly, train it, it may not be unusable, really when he crosses, take a few mobile phones over, teach the Northern Song Dynasty people to lock the screen and unlock, the Northern Song Dynasty people may not be able to use it to play games.

Concentrated fluid mechanics, and other knowledge that Zhao Xin didn't even think of, but the effect was very good.

Under the crazy action of dozens of people, the fighting ship rushed to the ice at a speed of about 6 knots, and the speed of 6 knots was inconspicuous in later generations, in this era, it was definitely very fast, almost more than 10 kilometers per hour, and the unique bow design also made these ships, when breaking the ice, there was almost no stagnation, and the speed was almost not reduced, but the ice was broken through, when the 5 icebreakers broke the ice respectively, so that the complete ice began to break. Further destruction of the ships behind.

There is also such an operation, which is something that the people around them did not expect, they have lived on both sides of the Bianhe River for a long time, of course, they know that as long as the Bianhe River freezes, it is a Jedi, and even when Bianliang is short of food, there is no way to transport grain through the Bianhe River, let alone others.

Now, I found that such a simple fighting ship can actually break through the ice, even if it is only temporary, which is also a great change for Bianhe, and maybe, when it is really needed in the future, it can be used.

The icebreakers, probably 30 miles away from the entire fleet, they spent a few hours to clear a road, not to delay the march of the main fleet, no, by noon, the icebreakers, had gone inward, gradually towards Bianliang, a large fleet, began to appear on the Bianhe River.

Even in the summer, when the water is at its highest, there has never been such a large fleet.

On the Bianhe River, the largest ship, that is, the ship of 1000 stones, but those ships, at most, are three or five, after all, in the Northern Song Dynasty, except for the Dinghai Navy, the other production capacity is limited, even if it is to Bianliang Cao transport ships, it is also based on the state capital, there are few large-scale, this era, has not yet realized that the benefits of large-scale transportation, can exceed 5, it is already amazing.

Now, with a huge, almost endless fleet, huge, extremely oppressive, these people realized what the previous ships were for, and this was the precursor of these ships, clearing the way for them.

Looking at this ship, you know that this fleet is not simple, 100 such a large ship combined, what kind of existence is this net worth.

That's how the workers and merchants on the docks see it, but when they pass through the state capital, it's different.

Whether it is the icebreaker in front or the huge fleet in the back, it is not simple, in fact, when the ice was broken before, these officials have already been alarmed, they don't know what these ships are here for, in case it affects the Bianhe River, it will be a big trouble.

Now, it is even more like such a huge fleet, when it freezes in winter, what does such a fleet want to do with such a majestic coming.

Whether it is the duty of defending the land or something else, these people need to show their presence and come to Bianhe one after another.

But when they arrived at the Bianhe River and saw the fleet and the flags on the fleet, they immediately understood.

Dinghai, this was still unknown more than a year ago, but now, it is like thunder, a person who has terrible wealth, and even the existence of a magical Dinghai coin, this is not something they can offend, in the same way, they have also received a notice from their superiors before, and the nearest Dinghai privy envoy is coming, let them pay attention to the reception.

In the eyes of the entire high-level, Zhao Xin most likely came by land, but he didn't expect that he would come from the water so strongly.

After the ice, the Bianhe River is not accessible to any ships, but this point has changed here, since then, in winter, there are hundreds of icebreakers on this side of Bianliang, at the critical time, break the ice, facilitate the fleet to enter and exit, so that Bianliang here, the real year is navigable.

Because the fleet did not dock in all the counties, the Bianhe River was very wide, and coupled with the frozen relationship, there were no ships, as long as they stayed on the river.

In fact, after entering the Bianhe River, with the icebreaker breaking the ice, they did not have any stop, and with a familiar person as a guide, it was easy to walk through this final journey.

These local officials, of course, will not just watch, they themselves are prepared, if the Dinghai stays, they will definitely do their best to entertain the Dinghai, the Dinghai is too rich, just pluck the hairs, it is enough to make them full, even if they don't stay, they will report to Bianliang through their channels.

Heavy snow closed the road, people and horses are difficult to travel, but they are not afraid of difficulties, only afraid of people with hearts, after all, horses are a little faster than ships, after countless people reported the news, Bianliang here, also knew about Zhao Xin's arrival.

For Zhao Xin to be so unexpected, coming from the water, this is something that no one expected, but the way to break the ice, this is also something that no one thought of before.

In the past, because the winter was too cold and lasted for a long time, the Bianhe River was frozen for more than 2 months, much more than usual.

Bianliang has a population of one million, these populations, it is certainly impossible to reserve, enough for Bianliang to eat a whole winter of food, once the ice and snow melt late, then for Bianliang, it is a very severe test, some people also proposed, with the method of icebreaking, but the icebreaking, almost desperate.

In normal times, a person can always dig out a few earthworks by spending a little time, but when dealing with ice, it is different from soil, ice is almost as hard as stone, and most importantly, there is a great danger, once the ice is close to the water, it is easy to cause danger.

However, using the method of boats, naming ships that cannot deal with the ice, but breaking the ice like a bamboo, and opening a road that is enough for a ship to pass through 1,000 stones, even if it is only in early winter, the ice is not hard, this is a method after all.

Some of the people who manage the Bianhe River have even paid attention to this icebreaker, and if Bianliang has these icebreakers, it will definitely be very good to use.

Zhao Xin is getting closer and closer to Bianliang, and Bianliang is also preparing, especially those docks, in winter, the entire Bianhe River is frozen, and the busy Bianliang wharf has lost its former liveliness, not only are all kinds of people gone, but even the wharf itself is a lot calmer.

Now, Zhao Xin came from the waterway, and it was a fleet of 100 ships with 1,000 stones, in this case, under the premise that there were still a day or two before Bianliang, they had to make preparations in advance, and to put it bluntly, if there were not enough personnel to be responsible for reception and docking, and to carry things by the way, the goods on these ships would not be unloaded.

1000 stones, imagination is very terrible, 100 ships, almost 100,000 stones, even if you can take down a stone at one time, it takes 100,000 times, if you find 1000 people, you have to unload at least 100 times.

If you change it to weekdays, let alone find 1,000 people, 10,000 people, it is also very easy, Bianliang is the most important city of the Northern Song Dynasty waterway, in the entire Bianliang, there are at least more than 18 large and small wharves, around these wharves, each wharf work, more than 2,000 people, that is, there are almost 30,000 or 40,000 people, around the entire water transport life.

Now, there are less than 30 days left before the New Year, coupled with the frozen relationship, the water transportation of the entire Bianliang has been cut off, and most of the people from the surrounding areas have gone home for the New Year, and some people who have been doing odd jobs on the dock for a long time will also go to rest after a year of hard work and accumulation of enough money.

These people don't, just by virtue of being in Bianliang, they can find less than 1,000 people at most, and not everyone can reach it smoothly.

After all, the entire Bianliang City is so big, under the premise that they can only use walks and carriages for action, it is definitely impossible for these laborers to ride in carriages, they can only use their feet.

Zhao Xin arrived immediately, what to do with this unloading, but soon, a smart person thought of a way, began to contact the Privy Council, after some negotiations, a 2,500-strong forbidden army, took off all their arms, left the station, and went to the dock where Zhao Xin was going to dock, located near the Privy Council, they would be responsible for unloading all the things on the ship, and according to the requirements of the Dinghai, sent to a special warehouse.

The strength of the Dinghai Navy in Bianliang has been quite large, not only forming shops all over Bianliang, but also setting up a large number of warehouses in various ports, and the one near the Privy Council is the largest, because the largest business between the Dinghai Navy and the Northern Song Dynasty is iron and steel, and the goods transported over cannot be used on the spot, so they can only set up warehouses near the port, store them, and then release them one after another.

Now, in the winter, most of the warehouses are empty, just in time for this time the goods are used.
