Daming: I asked you to hang yourself, but I didn’t ask you to rebuild the Ming Dynasty

At the end of the poem, Cai Gui sighed:

With this kind of ship that can break through the ice, the merchants of the Song Dynasty sailed on the ice of the Bohai Sea as silky as a spring breeze.

The icebreakers of the Song Dynasty used the icebreaking principle that the wind drove the hull to rock, so that the iron cone on the bow broke the ice.

The bow of the ship is made of iron to prevent the ship's side from being broken by the hard ice.

This is completely consistent with the thinking of later generations of ironclads.

The icebreakers of later generations are still bulky and heavy, especially the front part. This is completely consistent with the icebreakers of the Song Dynasty.

There are two ways to break the ice:

First, use power to crush the ice from top to bottom and move forward.

Second, use power and buoyancy to move forward against the broken ice from bottom to top. (Da Mao pioneered it. In principle, this method is the least labor-intensive.)

However, no matter which method is used, the principle of the icebreaker in the Song Dynasty is the same.

——They all rely on external force to break the ice so that the ship can move forward.

The only difference is due to the limitations of the times, the differences in power machinery and hull size.

Gong Yonggu became furious.

This gentle and elegant prince-in-law in the past has changed his old ways since he was ordered to accept the important task and went to Nuerqian in the face of danger.

In the three years since he went north, he has become accustomed to seeing life and death. His youthfulness has faded away and his body has been enriched.

As the leader of the army, with the confidence to regain thousands of miles of mountains and rivers, Gong Yonggu also had the domineering aura of a high-ranking person.

As a member of the royal family, Gong Yonggu, who owned 25 large and small islands and had a land covering more than miles of land, immediately made up his mind to develop an icebreaker.

Look up and look east.

Hundreds of large and small warships are docked in the harbor.

Although the battleship could not move due to the ice, the rolled-up sails and forest-like masts that stretched to the sky were Gong Yong's confidence.

Gong Yonggu took a slow breath and walked towards the Governor's Mansion.

The three northern provinces are temporarily military-controlled areas.

Hongwu Province, where he and Liu Wenbing are based, is not that cold because it is very close to the sea.

Over in the Arctic Province, there are people who are too cold to pee in the wild.

but……

Gong Yonggu looked at the towering chimney of the Governor's Mansion and smiled.

With glass and earthen kang...

Isn’t this north so unacceptable?

His Majesty told him to return to the capital this New Year.

It’s time to leave!

Although the railway line from Nurgan City to the south via the three eastern provinces, through Shanhaiguan, and to Handu is still far away.

However, thanks to His Majesty's emergency repairs at all costs, the railway going south via Beihai and through the grassland has basically been completed.

If he is in a hurry, he can take the steam train to Khabarovsk, then rush to Beihai and take the steam train south.

Of course, there are still hundreds of kilometers of mountainous terrain that require a sleigh ride.

He also has a second road, the direct railway from Nurgan City to Vladivostok, which has been opened to traffic.

He could have traveled to Vladivostok first, then boarded a warship in Vladivostok, bypassed North Korea, and entered the Bohai Sea.

One month is enough.

"Liu Wenbing, didn't we agree to meet up in these few days?"

Gong Yonggu covered his cold and sore nose with his hands.

"Forget it, wait for him for two more days. If he doesn't come again, I'll really have to hit the road.

Calculate the time, if you delay it any longer, I'm afraid you won't be able to keep up with participating in this year's Xindan Dynasty! "

Gong Yonggu walked towards the Governor's Mansion while talking to himself.

Yongle Province Governor's Mansion is a new Chinese-style building.

In the inland provinces of the Ming Dynasty, the setting up of governors has been abolished, and the system of separation of powers has been restored, with the administrative envoys in charge of the people, the commanding envoys in charge of the army, and the inspectorate envoys supervising administration.

Only in newly occupied areas will a governor be established to take over military and political power.

Every governor-general's palace is not only an important political and military center of a province.

Every governor is an important helper for Zhu Youjian's external development.

In order to establish the authority of China, the Governor's Mansion was built to be tall, majestic and unparalleled.

There are three three-story watchtowers on each side of the tall fence.

On the watchtower, there are snipers on the third floor, and three one-inch rapid-fire cannons on the second floor.

The first layer was built into the wall, with only a dozen small shooting openings aimed at the outside.

The hole was only one inch square, just enough for the soldiers inside to aim outside.

The inside of the shooting hole is high and the outside is low, and it can prevent the enemies besieging the Governor's Mansion from throwing explosives into the hiding cave.

At the top of the wall, there is a "concave-convex" parapet structure, which is the crenel.

Behind the wall, there are bungalows that are lower than the wall. They surround the wall, with only the front and back doors disconnected.

The roof of the bungalow is three feet (one meter) away from the lowest "notch" of the crenel, which is for the convenience of artillery shooting, throwing stones, and throwing gold juice.

The highest "protrusion" from the crenel is four and a half feet (1.5 meters) high, which is used by soldiers for shooting.

Moreover, this height is enough to cover the movement of internal soldiers.

At the gate, there are two four-story watchtowers standing opposite each other.

After adopting the breech-mounted flash cap and custom-installed Yongsheng rifles, the firepower of the Ming army's infantry has been close to that on the eve of World War I.

It can be said that a governor's palace defended by 2,000 people is enough to withstand the siege of 200,000 Western soldiers.

Therefore, the gate of the Governor's Mansion canceled the original door-type construction of Huaxia.

Instead, a fence gate was adopted.

Every Ming soldier is a valuable asset.

In order to minimize casualties, these fence gates are designed to be opened without the guard having to step out.

Simply put, there are two gate posts on both sides, each with two ropes connected to the fence telescopic gate.

The bottom of the fence gate is equipped with a small wheel.

As long as the corresponding rope is pulled, the fence gate can be opened and closed.

Of course, this fence gate is just a daily state.

If you are really attacked by a strong enemy, you only need to push the steel gates that are usually open to both sides of the city wall to the entrance position. Once the gate is riveted, the entire Governor's Mansion will become a fortress city.

The wall is only the first line of defense of the Governor's Palace.

This is just where the day-to-day defenses are.

Inside the wall, the thirteen-story reinforced concrete building is the real killer!

Although from the outside, the Governor's Mansion is surrounded by glass, it seems to have no military capabilities.

In fact, the entire Governor's Mansion is not only equipped with tempered wired glass, but also has a ready-made shooting position after opening the corresponding glass window.

The Governor's Mansion is equipped with 16 General Bi cannons!

Reinforced concrete buildings can not only resist artillery bombardment, but also withstand the recoil of large-caliber artillery fire.
