"Let me tell you a little bit about the situation in the Binghua Kingdom.

The land area of the Binghua Kingdom is nearly the size of the two Kadri Empires, and it is the largest country on the Kadri planet. The Kingdom of Ice is bordered by the Kadri Empire to the south.

Seventy percent of the total area of the Kadri Empire belongs to the middle temperate zone, warm temperate zone, and subtropical, so the Kadri Empire has a predominantly warm climate.

The Binghua Kingdom is mainly based on the ice field climate, the ground is mostly covered by thick ice and snow, cold all year round, and there are many cold storms, and plants can hardly grow.

The average thickness of the ice in the Binghua Kingdom is 2,000 meters, and the maximum thickness is more than 4,000 meters. The average annual temperature of the country is minus 20 degrees Celsius, the average temperature of the plateau in the central region is about minus 50 degrees Celsius, and the extreme minimum temperature has reached minus 90 degrees Celsius.

Ice Floe City is located in the southern region of the Ice Hua Kingdom, very close to the Kadri Empire, and the climate is relatively warm, relatively close to the northern cities of the Kadri Empire, so it's okay.

Most of the area of the Ice Flower Kingdom is entirely glaciers, especially in the central and northern regions, where it is difficult for humans to survive, and it is the real extremely harsh environment. ”

Is this where people live?

Ling Yan was secretly surprised in his heart.

Looking at Ling Yan's surprised expression, Ye Bingna couldn't help but laugh and said, "It's amazing, right?"

Obviously, the environment of the Kadri Empire is superior, but the environment of the Binghua Kingdom next to it is so bad.

The exact causes of environmental polarization are unknown.

However, it is precisely because of the poor environment of the Binghua Kingdom that the Kadri Empire has no desire for the Binghua Kingdom at all. And the Binghua Kingdom also bowed to the Kadri Empire and obeyed its orders.

The harsh environment also caused the Ice Hua Kingdom to be sparsely populated, and the high-level originators basically flowed out to the Kadri Empire.

The Binghua Kingdom is the largest desert in the world, because the desert is generally a place with an annual precipitation of less than 250 mm, so cold places can become deserts just like hot places, which means that especially in the central region of the Binghua Kingdom, there is almost no snow.

This is because the conditions for the formation of snow are not only low enough temperature, but also high humidity in the air. And because the ice kingdom is too cold and the air is very dry, it rarely snows. As the latitude increases, precipitation decreases significantly, and there is almost no snow in the central region. In the coastal and southern regions, there is some snowfall.

The Binghua Kingdom is the coldest country in the world, and the climate of the Binghua Kingdom is characterized by the fact that the average or extreme temperature is lower than anywhere else in the world, regardless of the cold or warm season.

The Binghua Kingdom is also a huge natural cold storage, which is an important storage place for fresh water in the world, with about 70% of the fresh water resources of Kadri Star.

The most terrible weather in the Binghua Kingdom is storms, blizzards, and in the central region, there is strong radiative cooling, and the Binghua Kingdom also contains a large amount of wind energy that can be utilized, making it an ideal place for effective use of wind energy. A large amount of cold air near the surface is accumulated, and under the action of gravity and pressure gradient forces, a glacial descending wind with high wind speed, strong destructiveness and constant wind direction is formed. ”

Ling Yan, who was listening carefully, nodded slightly.

It's really cold here.

Even though it wasn't snowing, the pedestrians on the streets were still wrapping themselves tightly and hurrying along.

Even with Ling Yan's physique, he felt cold.

"Although the Binghua Kingdom has been urging people to have more children, the total population has never been able to rise.

One is that although the territory is large enough, the area that is truly suitable for human habitation is far smaller.

Second, because the climate is too cold, the food problem has become a major constraint on population growth. The state itself is not suitable for growing crops. Especially in ancient times, the food problem was particularly severe.

In the past, when science and technology were not developed, in order to resist the severe cold, the people of the Binghua Kingdom had to let the children adapt to the ice and snow from an early age, and when the weather was still good, they would wrap the baby tightly, and then show their delicate little face, and take the baby out to adapt to the cold climate.

In the eyes of the people of Binghua Kingdom, it is good for children's health to let children get in touch with nature and get used to nature from an early age.

For older children, adults encourage them to go outdoors and develop their brave character by beating in the snow and ice.

In addition, when it is particularly cold, the people of the Binghua Kingdom will wear very thick animal skins to keep warm.

Most of the people of the Ice Blossom Kingdom, especially men, love to drink, and they will warm up their bodies by drinking because they believe that drinking alcohol will keep them warm.

Due to the harsh environment of the Binghua Kingdom, for a long time, the buildings of the Binghua Kingdom were mainly Passive Houses. Passive house means that in cold climates, the building does not need heating equipment and air conditioning systems, and only through the insulation of the envelope structure can achieve a more comfortable indoor environment.

In extremely cold climates, many of the ancient buildings left behind in the Binghua Kingdom do not even need a heating stove to maintain a relatively comfortable indoor temperature. At that time, this effect was achieved mainly by high-quality insulation structures, which were made up of multiple layers of materials with a thickness of more than one meter. Most of the ancient buildings look thick and sturdy.

Up to now, the Binghua Kingdom, as a vassal state, has closely followed the pace of the development of the Kadri Empire, with rapid scientific and technological progress and rapid economic development. Ye Bingna gushed endlessly.

Ling Yan listened intently.

Ye Bingna slid her fingers over the azure blue virtual desktop in front of her, carefully read the information on it, and said, "With the advancement of technology, the facades of many high-rise buildings have adopted 'breathing' facades.

Many high-rise buildings have put on double 'cotton clothes' inside and outside. The outer layer is a very advanced double-layer hollow laminated glass window, with adjustable opening vents at the bottom, and the inner layer is a double-layer insulating glass window that can be opened inward, and there is a seventy cm gap between the inner glass window and the outer glass window.

When the wall 'breathes', fresh air enters the inner and outer windows from the bottom of the outer window, and is filtered or heated and filtered into healthy and clean fresh air at a suitable temperature and enters the room, and the turbid air in the room is discharged from the upper part of the inner window.

In the colder, the control system can heat the air between the inner and outer walls to form an air insulation layer, making the whole building feel like wearing a 'cotton coat'.

The whole system can adjust the air intake volume according to the climatic conditions to maximize the thermal insulation and thermal insulation effect, and its thermal insulation capacity is six to seven times that of ordinary exterior walls.

With the development of science and technology, because the Binghua Kingdom contains a large amount of renewable energy, with the progress and development of new energy technology, the wind and light of the Binghua Kingdom have begun to become a new power source here.

A solar heating system is used for heating, and high-power wind turbines are used to melt ice. The use of solar photovoltaic power generation, diesel power generation, wind power generation and battery power supply in one of the composite power energy technology, can make full use of solar energy resources and wind energy resources, replace or supplement the power provided by batteries and diesel power generation, and is very environmentally friendly.

The construction of a new energy power generation system in the Binghua Kingdom faces various problems, the biggest difficulty is the cold, the temperature of the Binghua Kingdom is extremely low, and the terrifying low temperature will cause the blades of ordinary fans to be frozen and brittle.

The application of lines and power distribution equipment in extremely harsh environments requires lines and power distribution equipment to withstand low temperatures, and even withstand low temperatures of minus 90 degrees Celsius in special periods, which is very difficult.

This allowed some places that could not be lived by humans in the past to be developed, and the population of the Binghua Kingdom finally began to grow gradually. ”

"Oooh. Ling Yan said.

Ten minutes later, the two came to a hotel, and the sign in front of the door was lightly engraved with four big characters: Binghua Hotel.

The overall ice blue of the hotel looks ordinary, the building itself has no characteristics, compared with the luxurious Kadri Royal Hotel, it is much more simple, and the luxury of the Kadri Royal Hotel, forming a sharp contrast.

The two entered the Binghua Hotel, because Ye Bingna had booked a room online early, the two simply checked in at the front desk, and then walked into the elevator in the corner, the elevator rose to the third floor, the door was wide open, and the two walked out slowly.

Ye Bingna booked a total of two rooms, one for each person.

After resting in the room for a while, Ye Bingna came to Ling Yan's room door and knocked on the door, Ling Yan followed Ye Bingna to get on the elevator again, walked all the way out of the Binghua Hotel, and then walked all the way in one direction.

"Where are we going?" Ling Yan asked.

"A safe place. Ye Bingna said in a low voice.

At this time, there were not many pedestrians on the road, and there were even fewer vehicles coming and going, the two walked on the street, although Ye Bingna was wearing a hat and covering her appearance, but her figure and temperament still attracted the attention of many people, and Ye Bingna did not pay attention to the eyes of those passers-by.

Unconsciously, it began to snow in the sky, and pieces of fine snowflakes fell with the wind, under the backdrop of pieces of snowflakes, although Ye Bingna was just walking smoothly on the street, she was like a fairy in the snow, and pieces of snowflakes fell, but when they were about to fall on Ye Bingna, they gently drifted down to both sides, and none of them really fell on Ye Bingna.
