Hidden Dragon in Qing Dynasty

A Expedition with more than five hundred people carried more than eight hundred horses. A team of such a scale was currently gathered, watching the five imperial guards as they dug out the hyacinth s.

Gordon's eyes were round. He was a British Engineer and was naturally interested in civil engineering, but he had never gone through training in cold zone battles before. He had no idea what these people were doing.

But when he heard that hyacinth like this was a compulsory course for the Chinese special forces, he immediately put away all his doubts and started to write down drawings in pencil.

At that moment, even the frail Sai Mouerbeike, the veteran explorer was interested, he had his people bring the sledge over, and lay on it as he watched Guan Lu and the rest work.

The snow on Horseshoe was already as thick as half a meter. With such thickness, it was enough to cut into snow bricks, each hyacinth was able to let two members lie down side by side, and rush towards the southeast with their heads facing northwest. Furthermore, the hyacinth was at an angle of 30 degrees.

After digging such a bed, they would be able to cover the top with snow bricks and build them one by one, using the loose snow to draw the gaps.

"We heard from the Führer when we were training that snow is the best thermal insulation material... "At first, we didn't believe it, but the results were amazing. The leader didn't lie to us …"

"The winter outside is even colder than here. Once the wind blows, even wolves and bears won't dare to go out in the later half of the night …"

"But as long as we dig out the hyacinth and light two candles, it would be able to raise the temperature … "Using the thermometer of a foreigner, even a hyacinth would be able to reach temperatures above zero …"

Sai Mouerbeike trembled as he asked, "Above zero... Wasn't the temperature above zero melting the snow? Isn't the hyacinth just falling? "

"No …." "The candles have such a small light. As long as you don't burn the snow bricks, burning them in the middle of the hyacinth will not melt the snow bricks …"

"Even this little bit of temperature will melt a little bit of the snow brick, forming a thin layer of ice on the surface of the snow brick..." "This layer of ice can even block the cold wind that's seeping in from the outside …"

Gordon watched as the hyacinth's lid slowly closed. He put down the pencil and asked, "I discovered that you guys dug out a angle of around 30 degrees, and there is even a turning point upwards at the entrance. "Why is that?"

"It's very simple!" "Because the heat is going up …" Duo Luo would never have thought that a bodyguard of the Great Qing would be able to explain the natural sciences to a foreign devil.

At this moment, he would no longer complain about those boring science lessons in Ryukyu. Those simple physics, chemistry, mathematics, geography, astronomy … All these combined into a simple subject, the Head of State named it Science.

It was precisely in such a classroom that Manchu like Duo Luo and Guan Lu actually knew the attraction of Earth, knew the principle of hot air moving up, and understood the principle of heat conduction. They were even able to explain why the quilt was so warm.

Everyone in Beijing, including the Emperor, thought that the quilt would warm up on its own.

Only after attending science class did Duo Luo and the others understand that the quilt would not heat up. The main reason why people could feel warmth was because the cotton sheet prevented the body from losing heat.

It was easy for a hyacinth to be dug out, but to explain the logic behind it, one really needed to have a bit of the basis of natural science.

"The heat is going up, so hyacinth have to have an inclined angle. The entrance has to be at the lowest point, while the people have to curl up at a high point!"

"In this way, wouldn't the temperature of the human body, as well as the temperature of the candles, be completely submerged in this hyacinth? The cold air outside can't match up with the warm air inside... Aren't we saved! "

Ouch … Gordon smacked his forehead, "So that's how it is. I understand, this hyacinth is indeed very scientific … Everyone, do you understand? "

"Two people in a group, hurry up and choose your position, and dig out hyacinth s …" "All the horny students gathered behind the leeward wall to warm up!"

"It's now half past three in the afternoon …" They had to make sure that everyone was able to enter the hyacinth before nightfall … "God bless me, I finally found a way to spend the night without the use of a bonfire …"

The members of the Expedition began to get busy. Under the command of Duo Luo and Guan Lu, simple and crude hyacinth s that could save lives were dug out.

There was not enough fuel to waste, in the entire Expedition, only the sick were qualified to drink some hot water. In the entire camp, only a bonfire was used to boil some life-saving water, the rest of the people had already drilled into the hyacinth s to eat cold cakes.

Guan Lu and Duo Luo carefully snuck into the hyacinth, curled up their bodies and lit two tallow candles, and the inside of the hyacinth immediately lit up.

The hard, brick-like nan was roasted on a candle. If you put it in your mouth at the slightest temperature, you wouldn't be able to use your teeth to bite it. You could only use your teeth to chew and swallow after it had softened.

"Doro …" Do you know what I want to eat right now? Old Tofu... Ten consecutive bowls of old tofu and I want the most tender legume … "

"I just opened my mouth and drank. I didn't even need to chew it with my teeth … My appetite can't eat hard anymore! "

"Enough of that, I'm dying of gluttony. There's still the noodle soup, the kebab cake, the fried cake, the big youtiao, and the oily tea …" Wu wu wu … "I miss home, I miss death …"

There was a limit to human emotions. Even if a man were to reach the pinnacle of his emotions, he would still cry. In any case, there were only two people in the hyacinth, so it would not be shameful if he did not say it.

Holding the ice-cold nan in their hands, the two of them wiped away their tears for a long time. When their emotions were finally released, they heard that the northwest wind outside had become even more violent than it was during the day.

The level seven and eight gale wailed like wolves as it wreaked havoc on the Horseshoe. The wind carried the snowflakes and pounced towards the hyacinth. As the sun went down, the temperature at night became lower and lower.

Gordon hid inside the hyacinth to take care of Sai Mouerbeike. When the wind blew, he took out the mercury thermometer specially made by the Expedition, and pulled it in to record the temperature after letting it out for ten minutes.

He measured them every half an hour, and found that within two hours of nightfall, the temperature dropped from -16 degrees Celsius to -30 degrees Celsius!

"My God! This hyacinth really works … The temperature inside is minus two degrees Celsius, and we're not cold in our furs at all … "

"The miracle of the Chinese! "How did they come up with such a method …"

Sai Mouerbeike looked at the diary that was written on Gordon's notebook, and muttered to himself. "Actually, these experiences are not new, the Eskimos from the North America and the people of the Far East of Russia all have these kind of snow houses …"

"It's just that we haven't done any research before! but the Chinese got it first... "
