There were more than two hundred coconuts dropped. On average, each soldier could drink two coconuts without a problem. However, one coconut was enough. Only a small number of soldiers drank two coconuts. Most of them were not thirsty after drinking one coconut.
When people were thirsty, the horses would be thirsty too. After drinking the coconut juice, some of the soldiers led the horses to the river and let them drink some water. The treatment of the horses was naturally not as good as that of the people. Coconut juice was such a good thing that it was always for the people to drink. The horses could only drink water from the river.
After drinking their fill, they naturally continued on their journey. The forest with prey was further away. The deeper they went into the forest, the more prey there would be. After all, the prey was also afraid of humans. As long as there were survival resources in the depths of the mountains, they would not take the risk to enter areas with human activities. This showed how terrifying humans were.
"This valley is really hot! It's much hotter than the weather outside. There's no wind at all. "
After Li An entered the valley, he discovered that the valley was relatively hot. The temperature wasn't actually that high. The main problem was that there was no wind in the valley. If there was no wind, the temperature would naturally be higher. This was a very natural problem.
"Big Brother, it's the mountains on both sides that block the wind. That's why this valley is so hot."
Li Feiyu said as he reached out to wipe the sweat on his forehead.
Many soldiers noticed this feature. As long as they were not fools, they could see that this valley was relatively closed. It was like a basin, and the wind from outside could not easily enter.
However, the principles that Li An understood were slightly more than the soldiers.
"Not only that, the mountain on the north side of this valley is concave, forming a sun-creating potential. The heat cannot be emitted, so it's naturally hotter."
Ang Lee said.
"Sun-Creating potential? What do you mean? "
Li Feiyu did not understand what it meant.
This was actually the principle of reflection. Under normal circumstances, when light and temperature shone on the ground, the ground would emit it. However, the special terrain of this valley caused the reflected heat to remain in the valley. Due to the angle of the mountain on the north side of the valley and the sun, the reflected heat was not directed vertically to the sky. Instead, it was directed parallel to the valley, causing the temperature in the valley to be unusually high.
It was as if countless people were holding small mirrors and pointing the reflected sunlight at a place. This way, that place would definitely be illuminated very brightly. Moreover, the temperature of that place would also be very high. This was the principle of this place.
"What I mean is that the terrain here is like a basin. It's also very similar to the solar stove we used before. Do you remember the solar stove I invented? Isn't the terrain very similar to the solar stove? The solar stove adds all the energy of the stove surface to one point. The situation in this valley is similar. The sunlight of the entire valley, the same as in the middle...... However, the reflected energy of the stone and soil............................................
. "Ang Lee explained.
"Big Brother, you're right. So that's how it is! No wonder it's so hot here. Hahaha! This is a natural solar stove. It must be very comfortable to live here in the winter. "
Li Feiyu quickly understood the reason for the heat in the valley and said with a smile.
Ang Lee looked around the valley and suddenly realized that there were traces of a large amount of water flowing through the ground. However, there was no river in this valley. How could there be such traces?
The only explanation was that there was a sudden flow of water in this valley, causing the scouring of a river.
"Big Brother, there's a very shallow riverbed here. The bottom of the river is dry. It seems that the climate here is too dry and the river water evaporated quickly."
Li Feiyu urged his horse forward and saw the riverbed not far away.
Ang Lee urged his horse forward and saw the shallow riverbed. Because it was not very obvious, it could not be seen from a distance.
"It seems that not only is the climate in this valley very hot, but it also has a lot of rainfall! These riverbeds are obviously new. Who knows, it might rain soon! "
Ang Lee suddenly thought of something and said.
In many places with strange topography, there would be very strange weather characteristics. For example, there would be thunder at a fixed time every day without exception. There were also places where it would rain every day or there would be frequent thunderstorms. Even neighboring villages would not have the same climate.
These very unique climates were generally determined by special topography and geological characteristics. The valley in front of them seemed to conform to the special topography. First, the temperature here was very high. Second, the wind outside was blocked and it was difficult to blow in. Therefore, the only way for the hot air gathered in the valley to circulate was vertically upwards. Because the temperature in the valley was higher than the temperature outside, when the hot air in the valley moved upwards and met the cold air in the high altitude, it formed the conditions for rain.
The so-called rain was caused by the convection of hot and cold air. When the hot air in the valley met the cold air outside, it was very easy for it to become rain. This might be the reason why this valley had so much rain.
"Big Brother, the weather here is so good. How can it rain just because you say it will? This is not possible. It is absolutely impossible. "
Li Feiyu shook his head. He felt that it was impossible to encounter a situation where it would suddenly rain.
Ang Lee looked at the sky. There was indeed no sign of rain. However, the area of this valley was not small. They had to pass through it quickly. Otherwise, once the climate in the valley changed, everything would be too late.
"Pass down the order. The army quickly pass through the valley. Go."
Ang Lee did not care if others believed it or not. In any case, he felt that there was a problem with this hot valley. If it suddenly rained heavily, they would be drenched. Leaving this valley as soon as possible was a wise decision.
Since Ang Lee had given the order, his subordinates naturally had to obey. The cavalry of a hundred men quickly rushed forward from this relatively large valley.
"Why did the weather change? It's dark."
Just as everyone was about to leave the valley, the weather in the valley suddenly changed. The originally clear weather suddenly darkened and the sky was filled with dark clouds.
"Oh no, it's going to rain. Retreat quickly."
Ang Lee did not have time to think too much. He quickly sped up and left. Although he had brought rain gear when he set off, there was only a small amount of rain gear that could satisfy a general like Ang Lee. Ordinary soldiers could only endure the rain.
For someone like Ang Lee who loved his soldiers as if they were his children, how could he bear to let them suffer in the rain? Naturally, he hoped that the soldiers would not be drenched by the rain. If he let the soldiers follow him to hunt wet, Ang Lee would definitely feel uneasy in his heart.
After crossing a high slope, Ang Lee and more than a hundred men safely left this strange valley. However, they were not in a hurry to leave. Instead, they stood on the high ground and looked at the difference between the inside of the valley and the outside of the valley. They sighed at the magic of nature.
"Big Brother, this is too magical. The sky outside is bright, but there are dark clouds in this valley. How can this be?"
Li Feiyu looked at the strange scene in the valley and asked curiously.
Indeed, this phenomenon was too strange. If it was raining, it should be raining everywhere. However, there were only dark clouds in the valley. There were no dark clouds outside the valley at all.
"Assistant Minister Li, is there a dragon coiling in this valley?"
A guard said.
Li An smiled. He didn't know how to explain it. It was too difficult to explain scientific knowledge to them because it was impossible for them to understand it. Even if he explained it, it would be a waste of effort.
"Hualala …"
Soon, a torrential rain fell from the sky and fell in the valley. This huge rainstorm hit the ground and made a loud sound. Many leaves were knocked down.
The torrential rain was ten meters in front of Ang Lee. However, there was not a single drop of rain where Ang Lee was standing. It was too magical. This phenomenon was probably only seen a few times in a person's life. It was a kind of luck to be able to see this phenomenon, a very big kind of luck.
"No wonder when I entered the valley, I found that there was not a single bird. It turns out that these small animals living in the mountains know that the climate in this valley is unpredictable. Therefore, they do not dare to settle down here. This is why there are no animals in such a huge valley."
Ang Lee sighed.
"Big Brother, this valley is too hot because of the sun. Why is it suddenly raining here? Can you at least explain it to us? "
Li Feiyu asked curiously. Humans were curious, especially about the unknown. It was human nature to seek novelty, no matter which era it was. Humans were like this.
Ang Lee thought for a moment and felt that it was necessary to explain. Therefore, he said, "Everyone knows about using a big wok to stir-fry!"
"I know. What does the rain in this valley have to do with using a wok to stir-fry?"
Li Feiyu was even more curious.
Ang Lee continued to explain, "When stir-frying in a wok, the temperature in the wok is high. It will produce a lot of water vapor. This water vapor will go all the way up. However, when it meets the lid, the water vapor will be blocked. Then, it will drip into the wok drop by drop. This is the principle of this valley. Do you understand?"
"The temperature in the wok is very high. The temperature in the valley is also very high. There is water vapor in the wok, but there is no water vapor in the valley! The water in the wok can meet the lid, but there is no lid in the valley! It's still not quite the same. "
Li Feiyu said.
Several bodyguards next to him also felt the same. They also felt that it was not quite the same.
Ang Lee knew that they did not understand. However, since he had explained it, he would explain it to the end. Therefore, he said, "There is water vapor in the air. It's just that the temperature in the valley is not as high as in the wok, so the water vapor cannot be seen. In addition, the lid is just an example. It refers to the cold air. When the hot air in the wok meets the cold air of the lid, it will turn into water droplets and drip into the wok. There is also relatively hot water vapor in the valley. After it rises into the air and meets the cold air outside, it will be like the water vapor in the wok meeting the lid. It will form small water droplets and fall down. However, the wok is very small, and this valley is very large. It can contain more water vapor, so once it rains, it will be a downpour."
After explaining for a while, seeing that these guys still did not seem to understand, Ang Lee was really speechless. However, if they did not understand, then so be it! These were all boorish people, and he could not expect them to understand. After all, the difference in times was very big. These people who had not been through systematic education, their level was very limited. It was normal for them not to understand.
"You still don't understand, right?"
Ang Lee said with a smile.
"En."
Li Feiyu and others all kept nodding.
"Ai, forget it. This explanation is very clear. If you don't understand, then forget it. I won't explain anymore. Enjoy it for a while, and let's continue on our way."
Ang Lee said.
"Big Brother, it's raining so heavily. If it keeps raining, how can we go back?"
Li Feiyu suddenly thought of a very practical problem. There may be many roads into the mountain, but they were not locals and did not know enough about the terrain. Therefore, it was difficult to find a new way back.
"What are you afraid of? It's rain, not knives. Even if there are knives, we don't have to be afraid. We have armor and helmets! Hahaha! "
Ang Lee said with a smile.
"Haha! Then the soldiers can only be drenched. I hope the rain will stop in the afternoon. "
Li Feiyu said with a smile.
Ang Lee took a stool and sat to enjoy the rainstorm in front of him. This kind of scene was rare in a hundred years. It would be a big loss if he did not see it. The soldiers had also not seen such a strange scene. If they did not take a few more glances, they would feel sorry for themselves. As for hunting, it was just a pastime. Watching the rainstorm was also a pastime. The situation was similar. Anyway, Ang Lee was not in a hurry to leave, so there was no need for them to be in a hurry.
"Big Brother, we have been watching for three minutes. Are we not in a hurry?"
Li Feiyu asked.
"Send a few people to scout ahead and see if there are any suitable places for hunting. We will rest and wait here."
Ang Lee proposed to go hunting in the mountain to pass the time. However, the rainstorm in front of him was too beautiful. If he did not take a look, he would feel sorry for himself. Therefore, Ang Lee wanted to stay outside the valley to watch the rain. As for hunting, he would let the soldiers choose the location first. After that, he would directly hunt on a large scale.
"Look at the plants in the valley. They are more beautiful than the plants outside. It is because there is enough rain and dew that they grow so well. Moreover, the higher the temperature, the faster the growth of the plants."
Ang Lee looked at the beautiful scenery in the valley and said.
"Not only that, after being watered, the dust on the leaves all fell. This way, the leaves naturally look more tender."
Li Feiyu said.
"Yes! There is a lot of rain in this valley and it has become a treasure house for plants. In places with many plants, there are many small animals. We did not notice it just now. Perhaps these animals know the pattern of the rain in the valley, so they will hide in other valleys in advance before it rains and come back after the rain stops. "
