There are more than two hundred coconut fruits dropped, and each soldier will not have a problem drinking two on average, but the amount of water in one coconut is enough, only a small number of soldiers drink two coconuts, and most of them will not be thirsty after drinking one coconut fruit.

People are thirsty, horses will also be hungry and thirsty, after drinking coconut water, some soldiers will lead the horses to the river, let the horses also drink some water, the treatment of horses is naturally not as good as people, coconut water is such a good thing, it is always for people to drink, horses can only drink water in the river.

After the people and animals are full, they naturally continue to hurry, the forest with prey is still farther away, the deeper into the forest, the more the number of prey will be, after all, the prey is also afraid of humans, as long as there are survival resources in the depths of the mountains, they will not venture into the area with human activities, which shows how terrible human beings are.

"It's so hot in this valley! It was much hotter than the weather outside, and there was not a hint of wind. ”

After Li An entered the valley, he found that the valley was relatively hot, and the temperature was not very high, the main problem was that there was no trace of wind in the valley, and if there was no wind, the temperature would naturally be relatively high, which was a natural problem.

"Big brother, it's the peaks on both sides that block the wind, that's why this valley looks so hot."

Li Feiyu said, reaching out and wiping the beads of sweat on his forehead.

This characteristic was seen by many soldiers, as long as they were not fools, they could see that this valley was relatively closed, like a basin, and it was not easy for the wind outside to come in.

However, Ang Lee understands more than the soldiers.

"Not only that, but the mountainous area on the north side of this valley is a concave shape, forming a yang-making trend, and the heat can't be dissipated, so it will naturally appear hotter."

Li An said.

"The momentum of the sun? What do you mean? ”

Li Feiyu didn't quite understand what it meant.

This is actually the principle of reflection, under normal circumstances, the light drinks the temperature to the earth, the earth will be emitted, and the special topography of this valley, resulting in the reflected heat is still in the valley, the mountains on the north side of the valley, because of the angle with the sun, the reflected heat is not perpendicular to the sky, but parallel to the valley, resulting in an unusually high temperature in the valley.

It's like there are countless people holding small mirrors and pointing the sunlight reflected by the mirror at a place, so that the place will be very bright, and the temperature of the place will be very high, and this is the reason here.

"I mean the terrain here is like a washbasin, and it's like the sun cooker we used, you remember the sun cooker I invented! Isn't it very desirable to see the topography here with the sun cooker? The sun cooker adds all the energy of the entire cooktop to a point, and the situation in this valley is similar, and the sunlight of the entire valley is also emitted in the open space in the middle, so it is so hot, but the reflected energy of stones and earth cannot be compared with the mirror after all, so we are not roasted, otherwise, we are already roasting meat now, haha! ”

Ang Lee opened his mouth to explain.

"What the eldest brother said makes sense, it turns out to be like this! No wonder it's so hot here, hahaha! This is a natural solar cooker, and if you live here in winter, it must be very comfortable. ”

Li Feiyu quickly understood the willingness of the valley to be hot, and said with a smile.

Li An looked at the situation around the valley, and suddenly found that there were traces of a large amount of water flowing through the road under his feet, but there was no river in this valley, how could there be such traces?

The only explanation is that the valley was surprised by the flow of water, which caused this river-like erosion.

"Big brother, there is a very shallow riverbed here, and the bottom of the river is dry, it seems that the climate here is too dry, and the river water quickly evaporates."

Li Feiyu rode his horse and saw the riverbed not far away.

Li Anzema followed, and saw the shallow riverbed, because it was not very obvious, so it could not be found from a distance.

"It seems that this valley not only has a very hot climate, but also a lot of rainfall! These riverbeds are obviously new, and it may rain soon! ”

Li An suddenly thought of something and spoke.

In many places with strange terrain, very magical climatic characteristics will occur, such as some places will thunder at a fixed time every day, without one exception, and in other places, it will rain every day, or thunderstorms will occur frequently, even neighboring villages will not have the same climate.

These very unique climates are generally determined by special topography and geological characteristics, and the valley in front of you seems to be in line with the special terrain, first of all, the temperature here is very high, secondly, the wind outside is blocked and it is difficult to blow in, so that the hot air gathered in the valley, the only way to circulate is vertically upward, and because the temperature of the valley is higher than the temperature outside, when the hot air in the valley moves upwards and encounters the cold air at the heights, this forms the conditions for rainfall.

The so-called rain is caused by the convection of hot and cold air, and the hot air in the valley meets the cold air outside, it is very easy to turn into a rainfall, which may be the reason why the valley is rainy.

"Big brother, the weather here is so good, how can it be said that it will rain when it rains? It's unlikely, absolutely impossible. ”

Li Feiyu shook his head, feeling that it was impossible to encounter a sudden rain.

Li An looked at the sky, it was true that there was no intention of raining, but the area of this valley was not small, and it must be passed through as soon as possible, otherwise, once the climate of the valley changed, it would be too late.

"Pass the order, and the army will quickly pass through the valley, and drive."

Li An didn't care whether others believed it or not, anyway, he felt that there was something wrong with this hot valley, and if it suddenly rained, they would be drenched in soup, and it was a wise decision to evacuate this valley as soon as possible.

Now that Li An had already given the order, his subordinates naturally had no choice but to obey the order, and the cavalry team of a hundred people quickly rushed to the front from this large valley.

"It's changed, it's dark."

Just as everyone was about to leave the valley, the weather in the valley suddenly changed, and the weather, which had been still clear, suddenly became dark, and the sky was full of dark clouds.

"Oops, it's going to rain, get out."

Li An didn't have time to think about it, so he hurriedly accelerated and left, although he brought rain gear when he set off, but only a small amount of rain gear could meet the needs of a general like Li An, and ordinary soldiers could only get caught in the rain.

For Li An, who loves soldiers like children, how can he bear to let the soldiers suffer in the rain, he naturally hopes that the soldiers will not be drenched in the rain, if the soldiers are soaked and follow him to hunt, Li An's heart will definitely be uneasy.

After crossing a high slope, Li An and his party of more than 100 people left this strange valley safely, but everyone did not rush to leave, but stood on a high place to look at the difference between the environment inside and outside the valley, and sighed at the magic of nature.

"Big brother, this is also amazing, the sky outside is bright, but there is a dark cloud in this valley, how can this be?"

Li Feiyu looked at the strange scene in the valley and asked curiously.

Indeed, this phenomenon is so strange that if it rains, it should be rain all around, but only there are dark clouds in the valley, and there are no dark clouds outside the valley.

"Li Shilang, there won't be a dragon coiled in this valley!"

A pro-soldier said.

Li An smiled, not knowing how to explain it, this scientific knowledge was too laborious to explain to them, because they were unlikely to understand it at all, and it was in vain to explain it.

"Boom la la ......"

Soon, a torrential downpour fell from the sky and fell in the valley just now, and this huge torrential rain hit the ground with a loud noise, and many leaves were knocked down.

Ten meters in front of Li An is the pouring rain, and the position where Li An is standing, but there is no raindrop, it is really amazing, this phenomenon is a person in a lifetime, it is estimated that I will not see it a few times, it is a kind of luck to see this phenomenon, a very big luck.

"No wonder when I entered the valley just now, I found that there was not even a bird in it, it turned out that these small animals living in the mountains knew that the climate of this valley was unpredictable, so they didn't dare to settle here, which led to such a huge valley, there are no animals to see."

Ang Lee opened his mouth and sighed.

"Big brother, this valley is too hot because of the trend of creating the sun, so what is the reason for the sudden rain here? Explain it to us! ”

Li Feiyu asked very curiously, people are curious, especially for unknown things, they are full of curiosity, and curiosity is also the nature of human beings, no matter what era people are.

Li An thought about it for a while, but still felt the need to explain, so he said: "You know how to stir-fry in a big pot!" ”

"You know, what does the rain in this valley have to do with stir-frying?"

Li Feiyu was even more curious.

Li An opened his mouth and continued to explain: "When you use a pot to fry vegetables, the temperature in the pot is high, and there is a chance to produce a lot of water vapor, which goes all the way up, but after encountering the lid of the pot, the water vapor is blocked, and then it drips into the pot bit by bit. ”

"The temperature in the pot is very high, the temperature in the valley is also very high, there is water vapor in the pot, and there is no water vapor in the valley! The water in the pot can meet the lid, but there is no lid on the valley! It's still not quite the same. ”

Li Feiyu said.

Several of the pro-soldiers next to him also felt the same, and they also felt different.

Li An knew that they didn't understand, but since it had been explained, it was good to explain it to the end, so he said: "There is water vapor in the air, but the temperature in the valley is not as high as in the pot, so the water vapor is invisible, in addition, the pot lid is just an analogy, referring to the cold air, the hot air in the pot meets the cold air of the pot lid, it will become water droplets and drip into the pot, and there is also relatively hot water vapor in the valley, after rising into the air, it encounters the cold air outside, just like the water vapor in the pot meets the pot lid, Small droplets of water will form, which will not fall, but the pot is very small, and this valley is very large, which can contain more water vapor, so once it rains, it will be a heavy rain. ”

After explaining for a while, looking at these guys as if they didn't understand, Ang Lee was really a little speechless, but if you don't understand, you can't understand! These are rough people, and they can't be expected to understand, after all, the difference between the times is very big, and these people who have not undergone systematic education have a very limited level, and it is too normal to not understand.

"You haven't understood yet, have you?"

Ang Lee said with a smile.

"Hmm."

Li Feiyu and the others all kept nodding.

"Hey, forget it, this explanation is already very clear, forget if you don't understand it, don't explain, enjoy it for a while, let's continue on our way."

Li An said.

"Big brother, it's raining so heavily, if it keeps raining, how can we go back!"

Li Feiyu suddenly thought of a very real problem, there may be many roads into the mountain, but they are not locals, and they do not know enough about the terrain, so it is difficult to find a new way back.

"What are you afraid of, it's rain, it's not a knife, even if it's a knife, don't be afraid, we have armor and helmets! Hahaha! ”

Ang Lee said with a smile.

"Haha! In that case, the soldiers will only be drenched, may God bless the rain in the afternoon. ”

Li Feiyu said with a smile.

Li An took a maza, sat and admired the rainstorm in front of him, this kind of scene is rare to see in a hundred years, if you don't look at it, you will lose a lot, and the soldiers have never seen such a strange scene, and they are sorry for themselves if they don't look at it a few times, as for hunting is just a pastime, watching the rainstorm is also a pastime, the situation is almost the same, anyway, Li An is not in a hurry to leave, and they don't need to be in a hurry.

"Big brother, I've been watching it for three minutes, aren't you in a hurry?"

Li Feiyu asked.

"Send a few men and horses to the front to see if there is any suitable place for hunting, and we will rest and wait here."

Li An proposed to come to the mountains to hunt, just for a pastime, but the rainstorm scenery in front of him is so beautiful, if you don't look at it more, some of them are too sorry for themselves, so Li An wants to stay outside the valley to watch the rain scene, as for the hunting matter, let the soldiers choose the location first, and then directly hunt on a large scale.

"Look at the plants in the valley, they grow more watery than the plants outside, because there is enough rain and dew to moisturize, they grow so well, and the temperature is higher, which is also conducive to the rapid growth of plants."

Li An looked at the beautiful scenery in the valley and spoke.

"Not only that, but after being watered, all the dust on the leaves falls off, so that the leaves look naturally more delicate."

Li Feiyu said.

"Yes! This valley has a lot of rain, it has become a treasure trove of plants, and there are many small animals in the place, I didn't find it just now, maybe these animals know the law of rain in the valley, so they will hide in other valleys in advance before the rain, and come back after the rain stops. ”

Li An opened his mouth to guess.
