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!”
