The weather was fair, and Long Yan occupied the port city.
Due to the influence of the cold wave, the temperature dropped sharply after experiencing several heavy rains.
Fortunately, Liu Zheng had already made preparations before the cold winter arrived.
He mined coal from the East India region that no one wanted to use locally and shipped it to Longyan Port.
In addition, the indoor smokeless heater developed by Liu Zheng based on the stove is actually a traditional coal stove.
It's just that when Liu Zheng made the stove, he used red clay as the core of the stove. This kind of soil is extremely resistant to burning and has excellent heat preservation properties.
Originally, the most traditional stove only had a furnace core without any protective measures on the outside.
This can lead to carbon dioxide poisoning produced by burning coal.
Although Liu Zheng improved the process and produced anthracite, this alone was not enough.
Anthracite is not truly smokeless, but it is less volatile and produces less harmful substances.
But it still existed, so Liu Zheng improved the stove.
The solid outer wall is made of airtight steel. In order to be foolproof, Liu Zheng also uses an ancient but never outdated production method.
Wax sealing method!
The sealing of the entire furnace wall is improved to a higher level.
To ensure the loss speed of heat and smoke.
At the same time, one side of the stove is designed as a heat conduction port. The heat generated by the combustion of the stove will enter the heat conduction port along with the generated smoke.
Follow the heat conduction port and enter the thermal insulation kang, which is also made of iron, to evaporate the heat.
The smoke generated by the burning stove will come to the outside along the iron pipe on the thermal insulation kang.
This creates a thermal cycle and increases the temperature.
"That's all we can do right now." Liu Zheng sighed and added a piece of coal to the stove.
Although the wind was biting outside and many people had thickened their clothes, Liu Zheng was wearing very thin clothes inside.
It is a replica of the water boiler that I knew in my previous life, but it cannot be achieved with current technology and design.
That kind of stove has a water pipe installed in the furnace wall, and the heat of the entire stove is supplied with temperature through thermal circulation of water.
The biggest advantage of this kind of water heater is that even if the fire goes out, the residual heat can last for a long time.
It's a pity that the material problem has not been solved yet. The water pipe must be one that is not easy to corrode, and it needs to be circulated.
Although the world has now experienced the industrial revolution, there has been no breakthrough in existing materials.
Only the craftsmanship has been improved.
Therefore, Liu Zheng eagerly wanted to develop electricity and accelerate his industrial level.
The efficiency of steam engines is too low. Even Long Yan's most advanced steam engines are far behind He Britain's steam engines in terms of core efficiency.
Although the Yinzhou ship is recognized as the strongest ship in the world, it is not yet out of reach.
At this time, a veteran general came in.
He was wearing a military coat. Although it was late autumn, the temperature outside made him feel like it was winter.
But now that he entered the house, the warm heat hit him, and he instantly felt like he was bathing in the spring breeze.
Liu Zheng glanced at him and asked, "What's the matter?"
The general gave a slight salute, and then said: "A large number of Austrian refugees have appeared around the city. Sir, do we want them to enter the city?"
Liu Zheng pondered for a while, very strange.
Their Long Yan Army did not go into full-scale war with Austria. At most, it was a confrontation. In addition, the situation in Austria is still relatively stable.
There will never be a large number of refugees.
Where did these Austrian refugees come from.
According to the situation in Austria, although this winter is difficult, it is not unbearable. There should not be so many refugees.
"Send someone to investigate what happened to Austria recently and why there are so many refugees."
…
Austria's capital, Vienna.
boom!
A piece of information sent to Vienna overnight was slammed on the table.
"Who can tell me what is going on!"
General Victor's angry shouts filled the entire House of Lords, and every Austrian official had a very ugly face.
General Victor's murderous gaze coldly glanced at everyone in the entire upper chamber.
They lowered their heads one by one, not daring to meet General Victor's gaze.
After several minutes of silence, someone broke the silence.
"General, it's not our fault for this."
General Victor laughed angrily: "You are all Austrian parliamentarians. The whole of Austria is now in our hands. If such a big thing happens now, the responsibility is not on us!"
"Is it on those refugees?"
The congressman who was having this conversation had a pale face and opened his mouth, but finally fell silent.
There was originally no parliament today, just because of this urgent report this morning.
General Victor ordered an emergency parliament to be convened.
"General Victor, we have just received the news, and we don't know exactly how these refugees appeared."
Another Duke said in a deep voice.
He looked at General Victor with a cold look: "But what is certain is that these refugees only appeared after the Holy Crusaders entered Austria."
Upon hearing this speculation, Victor's furious expression suddenly froze.
"However, there is no direct evidence that it is directly related to the Holy Crusaders. Everything needs to be investigated."
"Okay... Let's investigate."
General Victor slumped in his chair. Regardless of the outcome of the investigation, he had already guessed the most likely scenario.
Just hope everything is different from what he guessed.
And outside the Longyan port city.
This place is under the unified jurisdiction of the Longyan Army, although these are all refugees from Austria.
However, Long Yanjun did not drive them away, but instead set up temporary tents outside the city.
Provide these refugees with a simple place to live.
Distribute food and tell them that as long as they abide by Long Yan's laws and rules, they can be allowed to enter the city after the investigation is clear.
Upon hearing this, the refugees burst into cheers.
Among these refugees, there was a girl wearing earthy brown linen clothes who was surprisingly quiet. Although her face was tired and even a little dirty due to long hours of running around, she was eating big food at the moment. Long Yan distributed a food from their hometown - steamed buns.
The white and fat buns provided a sharp contrast to her dirty little hands.
Her eyes were extremely smart, and she looked at the Long Yanjun who were very busy in managing order, and her eyes were full of expectation.
After finishing the steamed bun in her hand, she swallowed her saliva and looked at the Longyan Army, a little confused, but finally mustered up little courage and trotted over.
Lifting up the hem of his skirt and giving a slight salute, the Long Yan soldier looked at this slightly different girl.
"excuse me……"
This Austrian is actually quite polite, Longyan Soldier thought to himself.
"what's the matter?"
"Is the current controller of this port a Longyan businessman named Liu Sheng?"
