After several days of continuous low temperatures, Su Qingluan guessed from his own experience as a northerner that the outdoor temperature in the past few days was definitely more than ten degrees below zero. Although it is not yet the low temperature of dozens of degrees below zero that I felt in the northernmost part of the country in my previous life, it seems that even the bones are frozen, but the ice on the surface of the river should be able to withstand the trampling of people.

However, for the sake of insurance, Su Qingluan still planned to go to the ice to squat down and observe the situation on the ice surface carefully.

Originally, Su Qingluan planned to go back to see it by himself, but the two little guys were also clamoring to go to the river, Su Guangfu and the Yang family of course didn't worry about letting Su Qingluan watch his younger brother and sister alone, so they also stayed together.

Before allowing his younger siblings to step on the ice, Su Qingluan carefully observed the nearby terrain - this section of the river was relatively open, there were no sudden narrowing channels or raised boulders, and there were no bridges.

This means that this section of the river basically does not have the topographical conditions to form a "clear ditch".

The so-called "ditch clearing" refers to the fact that the water in the riverbed suddenly becomes turbulent due to various reasons, although the surface is frozen due to low temperatures, but because the water flow is too fast, the water under the ice surface for a long time washes the water, which makes this part of the ice layer thinner and brittle.

In this case, it is also called "clearing ditch" because it will wash out a "trench" under the ice.

This kind of ditch clearing is very dangerous and difficult to detect from the surface, but if you step on it, the ice will break and you will fall directly into the water.

Unlike in summer, it is dangerous to fall into biting water, because the low temperature will paralyze breathing and stop the body, and the body will freeze and cannot move freely. Not to mention a landlubber, even if you are very good at water, you will be very likely to drown in such a situation.

However, the good news is that such ditches are in places where the water is fast, and such terrain can basically be inferred from the surface conditions.

However, for the sake of safety, Su Qingluan still tried it on the nearby ice in person, and then delineated the general range of activities of his younger brother and sister: "Well, you can come up and play if you want, I put those stones on the ice, you can't go out of the range specified by the stones, you know?" ”

Yang was still very worried: "Big girl, doesn't it matter?" We looked at the ice three days ago and it was only a thin layer. ”

Su Qingluan smiled and said: "Ah Niang, don't worry, you look at the texture on the ice, it is horizontal, this is the texture formed when the ice layer is first frozen, even if the ice layer is only a few inches thick, it can make people walk on it - not to mention the two of them, even if they are big men, it is not a problem." ”

Su Qingluan continued in his heart: "Don't say it's a person, even if it's an off-road vehicle weighing several tons, it can walk on the ground on such ice. ’

Anyway, fishing is not bad for this day, Su Qingluan thought that anyway, his younger brothers and sisters are here today, and there is no way to fish if he is noisy, so he just accompanies them to play on the ice for a while - in the previous life, every winter, the thick ice on the river surface can be turned into a ready-made playground.

Ice pumping, dog plowing, ice skating, ice skating, skating slides...... Su Qingluan thought of the lively scene in his previous life, and he gradually became a little interested in playing.

There are no skates now, but they ......

Su Qingluan took off the outermost non-slip spikes, leaving only the ordinary mille-feuille cotton shoes on the ice.

Now the temperature outside has dropped much compared to when the ice melts as soon as the sun comes out, and there is no chance of forming a water film, even if it is a mille-feuille bottom without slipping, it will not be too slippery.

Su Qingluan habitually kicked her back foot, and then quickly joined her front foot, and saw her suddenly accelerate and slide forward. After a few clicks, I found a feeling, and Su Qingluan "slipped" more smoothly.

To be honest, because the mille-feuille bottom has no non-slip texture, but the area of contact with the ice is much larger than that of real skates, it is relatively more stable than skates, but it is easier to glide on the ice than ordinary sneakers in the previous life.

Su Qingluan thought that there were no skates for her to play with at the moment anyway, so she simply "skated on the soles" like this.

With Sister A's permission, and seeing that she seemed to be sliding very interestingly, the two little ones immediately couldn't stand on their feet, and they were eager to try to play on the ice.

Su Qingluan turned his head to look at them: "Don't be afraid of wrestling, but wrestling must lie forward, don't tilt your head back!" "Although my younger brother and sister now wear thick winter hats on their heads, and the children have soft bones, they are not so easy to break, but Su Qingluan is still very cautious.

"On the ice, you have to lie forward, yes, your body forward!" Su Qingluan looked at his younger siblings.

In fact, she originally wanted to say it in advance, but whether it was her own experience or other people's lessons, it all showed one thing: even if she told it many times in advance, once she encountered an emergency, her body really fell, and she forgot all the warnings and points.

The only useful way is to let his younger brother and sister wrestle more from the moment they get on the ice, and keep correcting the posture of the two of them until they are used to the "correct wrestling posture." ”

Although I don't know why I want to "lie forward", but now Su Qingluan's words can be unconditionally complied with for my younger brother and sister, so the two little guys listened to Sister A's request, and stood on the ice and bent forward slightly, ensuring that even if they fell, they would show a posture of lying forward.

The same goes for Su Guangfu and Yang. However, the two of them are adults after all, they have a lot of concerns, and they are not so playful, when Su Xuanhe and Su Xueyan began to laugh and play, but because they couldn't control the good movement of their legs, they slipped and fell, these two could only tremble and dare not move easily.

After all, they are more afraid of falling than children – not only because older people have more serious fractures, but also because they are afraid of causing trouble to their children.

So not to mention playing on the ice, Su Guangfu and Yang didn't even dare to take off their spikes, they only stared at the three children for a moment, ready to rush over if the three children had a sudden attack.

Su Qingluan naturally didn't just care about playing, she wasn't a real thirteen or fourteen-year-old girl after all, so she looked at her younger brother and sister after playing for two laps.

"Sister, how did you skate? I want to skate too! After falling three times in a row, Su Xueyan wanted to play tricks, so she simply sat on the ice and couldn't get up.

Su Qingluan smiled: "You haven't learned how to use your strength yet—you see, your brother has done a good job." ”

Su Xueyan turned her head when she heard this, and found that although Su Xuanhe was still sliding, he was at least able to slide a distance on his feet.

The child was afraid of comparison, and the little girl who was originally sitting on the ground and playing tricks saw that the brother would slip, so she quickly got up and grabbed Su Qingluan's sleeve: "Sister, you teach me!" ”
