There was enough prey in the morning, and it was not eaten by noon, so there was no need for prey in the afternoon, but it was a good idea to catch some alive and bring it back to raise, and in the case of heavy snow, it became easier to catch prey alive, and the limbs of the prey would be trapped in the snow, which was much easier to catch than usual.

When the snow reaches one foot, the movement of small animals with short legs such as rabbits will be greatly restricted, and when the snow is more than two feet, even wild animals with long legs are difficult to move freely in the snow, and once the snow is more than three feet, even the largest prey, the movement in the snow will be greatly restricted, and it is very physically demanding, if the density of snow is relatively large, it is better, and if the density of snow is not large, it is more difficult for wild animals to walk.

Snow cover will become a huge resistance for wild animals to run, and the physical exertion of wild animals is huge, and humans can use skis, so that snow can become a huge boost for human action, so that under this trade-off, the advantage of human hunting is extremely obvious, and the small animals in the wild have suffered a great disaster.

The use of snow to catch prey alive, is not the patent of human beings, in nature, there are some smart hunters, will use the snow to hunt, and the receipt is not generally large, this wild animal is a smart little fox, this animal actually has the ability to hear the position, it can distinguish the position of the rodent below on the snow, and then jump up, jump up and break the snow to capture the rodent, to put it simply, it is to catch mice and other animals in the snow.

When hunting, they first listen carefully on the snow, and if they hear that there are rats or other animals under the snow, they will immediately get ready, adjust their body position, use the force of retreat to jump into the air, and then jump down to break through the snow and capture the small animal.

Because the snow is thick and hard, this is a difficult hunting technique that requires the fox to use all its body weight and can only be used when hunting in deep snow.

The reason why this little fox can hunt successfully is because of its relatively light weight, and the hardness of the snow is moderate, so that it can walk smoothly on the snow without falling into the snow all the time, and after finding the prey, the fox can use all its weight to break the snow with moderate hardness, and then capture the prey.

In other words, the hardness of the snow is just right for the fox, too soft will cause the fox to have a hard time, too hard will cause the fox to be unable to break through the thick snow layer and thus not be able to capture the prey, both conditions must be met at the same time in order for the fox to catch the prey it wants.

Snow like this, which can support foxes to walk freely on the snow, is relatively hard, so even if a rabbit comes, it can still walk freely on the snow, and it is more difficult for humans to catch it.

However, the hardness of the newly fallen snow on the outskirts of Datang Capital is very low, and even rabbits that weigh much lighter than foxes will be stuck in the snow, otherwise, the guards would not be able to catch the hare so easily.

Generally, the hardness of the snow is related to the time of the snow, the snow that has just fallen is generally very soft, and even the smallest animals will sink into it, but as long as the time passes, the snow will slowly harden, especially the top of the snow, which will form a very good hardness layer similar to the ice sheet, and the formation of this hardness layer is related to the exposure of sunlight.

For example, when it snows at night, the quality of the snow is very soft, but during the day, under the irradiation of the sun, the snow on the surface will melt, but because the temperature is too low, a small amount of snow water will soon freeze again, so that a lot of snow particles are welded together, and then a hard snow layer with a certain strength is formed.

The strength of this hard snow layer is related to the local climate, some are very hard, some are relatively soft, like the snow that the little fox hunted under the snow just mentioned, it is a relatively hard snow layer, the fox can walk lightly on it, without collapsing the snow layer, but as long as you jump into the air with all your strength, and then dive suddenly, you can break the hard snow layer with greater hardness, and then catch the prey under the snow.

The snow near Chang'an City is fresh, and there is not much time to melt and refreeze, so the hardness of the snow layer is relatively low, if the surface area of the skis is not large enough, it will definitely fall into the snow, and Li An is also because of this consideration, so the skis made are not only very long but also wide, wider than the surface of the foot, so that the ability to control the direction is much worse, and the flexibility is naturally greatly reduced, but in order to be able not to fall into the snow, this sacrifice is still necessary.

Determine whether an object will fall into the snow, the most important thing is the pressure of the contact surface, not that the heavier the object, the easier it is to fall into the snow, although the weight of the rabbit is very light, but the rabbit's legs and feet are too slender, in this way, it is easy to fall into the snow, not to mention the yellow sheep, the weight is many times that of the rabbit, but the size of the soles of the feet is not much larger than the rabbit, it is easier to fall into the snow, and the human foot is relatively wide, but the weight is not several times larger than the yellow sheep, and the pressure on the snow is relatively smaller, and after wearing skis, This pressure is even smaller, it can be directly reduced by dozens of times, and even, in the fluffiest snow, it will not sink too deep, and the front of the skis is slightly warped, so that a little bit of snow is slightly thickened, and the continuous gliding of the skis will not cause any effect, so that people can ski faster than the speed of wild animals.

Use skis to chase prey, the most important point is to dive from a high place, so that the speed advantage of skis can be brought into full play, if you slide from the ground to a high place, it will be very embarrassing, you can't catch up with the prey at all, so, when the smart prey sees the hunter skiing, it will run to a high place, so that you can get rid of the hunter's pursuit.

It's a pity that most wild animals are stupid, they just want to run down with less effort, and even can roll in the snow, but running up is very difficult, they prefer to run low, but they don't consider that when going downhill, skiing humans are much faster than them.

There is also the fact that the terrain in the wild is undulating, one will go uphill and one will go downhill, if they encounter such terrain, when they go uphill, they may open up the gap with humans, but as long as they reach the downhill terrain, humans can quickly catch up, so as to catch the prey.

Catching prey is what the guards do, after lunch, what Li Ang has to do is to continue to teach the two girls to practice skiing, and then play happily with them, of course, don't forget to make the dish of boiled sheep eggs, and let Li Yu take it when he goes back.

After sliding for a while, Li Yu was a little tired, so he stopped to rest, and Li An also rested with him, and the intimate guards soon brought two folding stools, that is, the folding stools invented by Li An.

After sitting down, Li An looked at the two girls who were still practicing skiing, and said: "Look at how happy they are, they should come out to play more, so that they can live more happily." ”

Li Yu looked at the two concubines who were becoming more and more proficient in skiing, was silent for a moment, and said: "The rules in the palace are very strict, where can I often take them out to play, besides, there are more than these two concubines in this king, there are many?" There are also a lot of royal uncles' daughters, there are hundreds of them in total, so you can't bring them all out to play! It was this time, they begged me, so they took them out of the palace for a while, and their status is not high, and no one will care if they are not in the palace for a while. ”

"Hey! What a pity! Ordinary people envy the nobility of the royal family, but they don't know that the children of the royal family also suffer, at least they are not very free, and they have to stay in the palace all day long, isn't this going to suffocate people to death, it's too painful! ”

Li An shook his head again and again, feeling that the people in the palace were too miserable to live, especially the women in the palace, who lived a particularly miserable life, and they didn't even have the most basic freedom, so they were not as comfortable as ordinary peasant women?

Li Yu heard this, that is very agreed, the royal family is good at everything, but it is too unfree, he is still free, but his father is not very free, he stays in the palace compound all day long, and even has to think twice before making a decision, life is too unfree, even Li Yu, every time he goes out, he must bring enough guards, and it is very difficult to do something by himself, and it has only been better in the past few years.

"Li Shilang is so right, this palace compound is not a good place, staying inside makes people breathless, it's better to be outside! With snow and fresh air, it would be very comfortable to live in a few huts in the middle of the forest. It's a pity that it's impossible for me in this life, and I'm destined to not be able to escape the palace. ”

Li Yu said helplessly.

"Yes! If one day, the king of Quang Binh ascends the throne, it is really inseparable from the palace, even if you come here to enjoy the snow scene, then you need to follow at least a few thousand people! ”

Li An said.

"Why is Li Shilang talking nonsense again, this king has never thought of becoming an emperor, Grandpa Huang is in good health, so there is no need to think about this matter."

Li Yu seemed a little scared and didn't dare to talk about this topic easily.

"It's just you and me here, it's okay to talk about it, anyway, God knows that you know and I know, and no one else will know, I really haven't thought about it?"

Ang Lee asked tentatively.

"Actually, I have thought about it occasionally, but it is not a simple matter to govern the world, and this king is worried that he will not be able to do it well! I don't dare to hope for it. ”

Li Yu whispered.

"No one is born to rule the world, many abilities are slowly exercised the day after tomorrow, King Guangping must have confidence in himself, I believe you will become a good emperor in the future."

Ang Lee said with great certainty.

"I'm going to be a good emperor in the future, really? Why is Li Shilang so sure? ”

Li Yu looked at Li An curiously.

Li An smiled and said: "I said that I can, King Guangping only needs to be the emperor's grandson, and things will go naturally in the future, it should be the throne of King Guangping, and no one can take it away." ”

For the succession to the throne of the Tang Dynasty, Li An is naturally very clear, however, this is under the premise that the historical conditions remain unchanged, and now many things have changed, so it is really difficult to say whether Li Yu can become the emperor or not, but Li An hopes that this guy can become the emperor, because this is a very good person, and after becoming the emperor, he will also be a good emperor.

"Alright! Just let everything go naturally, no matter who becomes the emperor in the end, I don't care, if it's my turn, I will do my best to be a good emperor. ”

Li Yu said.

"Well, that's right, don't pursue too much, don't evade, this is what King Guangping should be."

Li An was very satisfied, and when he looked up, the two little sisters fell one after another.

Skiing is not something that can be proficient in three or two days, for beginners, it is possible to wrestle at any time, and wrestling in the snow is also a process of exercise, for learning to ski, there is only benefit and no harm.

"Look at them, they're wrestling again, where are the girls."

Li Yu said with a smile.

"King Guangping, generally a spoiled woman, will become lawless, like a boy, but according to King Guangping, the status of the two sisters is very low, the prince almost never asked them, they occasionally have to do embroidery with the palace maids, to say that no one spoils them, the character should be very gentle and timid, how can it be like a man?"

Li An asked suspiciously.

Li Yu frowned and thought for a long time, and said: "Li Shilang is right, they were very obedient when they were in the palace, they were standard gentle women, even talking to low-level palace maids, they have never been loud, and they will be a little presumptuous in front of me, but this king is not used to them!" often yells at them, and Li Shilang also saw it. ”

"Haha! That's right, although King Guangping yelled at his two sisters, this is also a kind of love! It is the love of the elder brother for his sister, King Guangping think about it carefully, although you often scold them, have you deliberately troubled them, and after scolding them, have you ever helped them or given them benefits? Occasionally, when you have something good and you don't need it, will you give it to them? ”

Li An seemed to understand everything and asked.

Hearing this, Li Yu thought carefully for a moment, smiled at the corner of his mouth, and said, "What Li Shilang said is yes!" Although the king often scolded them, but took care of them, I remember when I was a child, there were delicious snacks to eat, I would give them to taste, of course, there was a reward, they ate the king's pastries, they had to do something for me, at least a few more compliments on me, or let me scold a few words, now it's interesting to think about. ”
