After several days of continuous low temperatures, Su Qingluan used his experience as a northerner to deduce that the outdoor temperature in these days was definitely more than ten degrees below zero. Although it is not as low as the low temperatures of tens of degrees below zero that were felt in the northernmost part of the country in my previous life, which seemed to freeze even the bones, the ice on the river should be able to withstand people's trampling.
However, to be on the safe side, Su Qingluan still planned to squat down on the ice and take a closer look at the situation on the ice.
Originally, Su Qingluan planned to go and have a look and then go back, but the two little guys were also clamoring to go to the river. Of course, Su Guangfu and Yang didn't trust Su Qingluan to watch his brother and sister alone, so they stayed together.
Before allowing his younger siblings to step onto the ice, Su Qingluan carefully observed the nearby terrain - the river channel in this section was relatively open, with no suddenly narrowing channels or raised boulders, and there were no bridges.
This means that this section of the river basically does not have the terrain conditions to form a "clear ditch".
The so-called "clear ditch" refers to when the water flow in the river bed suddenly becomes turbulent due to various reasons. Although the surface freezes due to low temperature, the water flow speed is too fast and the long-term water erosion under the ice surface makes this part The ice layer becomes thinner and brittle.
This situation is also known as "clearing the ditch" because it will wash out a "trough" under the ice.
This kind of ditch clearing is very dangerous and difficult to detect from the surface, but if stepped on, it will cause the ice to break and fall directly into the water.
Unlike summer, falling into the biting water in winter is very dangerous, because the low temperature will paralyze breathing and suspend the body, and the body will freeze and become unable to move freely. Not to mention a landlubber, even a person who is good at water is likely to drown in such a situation.
Fortunately, such clearing ditches are all in places with fast currents, and such terrain can basically be inferred from the surface conditions.
However, to be on the safe side, Su Qingluan personally tried a circle on the nearby ice before delineating the general range of activities for his younger brother and sister: "Here, you can come up and play if you want. I'll put them on the ice." Those stones, you cannot go outside the scope specified by those stones, do you understand?"
Yang was still very worried: "Da Ya'er, does this not matter? We looked at the ice surface three days ago and it was only a thin layer."
Su Qingluan smiled and said: "Don't worry, Mom. When you look at the texture on the ice, it is horizontal. This is the texture formed when the ice layer first freezes. Even if the ice layer is only a few inches thick, It can also allow people to walk on it—not to mention the two little cubs like them, even burly men can walk on it."
Su Qingluan continued in her mind: "Not to mention humans, even an off-road vehicle weighing several tons can walk on the ground on such ice." '
Anyway, it was not a bad day to fish. Su Qingluan thought that since her younger brothers and sisters were all here today, there was no way to fish with all the noise, so she might as well play with them on the ice for a while - in her previous life, every winter, thick formations formed on the river. A thick layer of ice can be turned into a ready-made playground.
Smoking ice, dog-pulled sledges, ice skating, skating slides... Su Qingluan thought of the lively scenes in her previous life, and she gradually became interested in having fun.
Although there are no skates now, but...
Su Qingluan took off her outermost non-slip spike shoes, leaving only her ordinary cotton-soled shoes and stepped onto the ice.
Now the outside temperature has dropped too much compared to when the ice melted as soon as the sun came out. There is no chance for a water film to form. Even if it is a non-skid layered base, it will not be too slippery.
Su Qingluan kicked her back foot out of habit, and then quickly brought it together with her front foot, and saw her suddenly speeding up and sliding forward. After doing this for a few times, he found the feeling, and Su Qingluan "slid" more smoothly.
To be honest, because the Melaleuca sole does not have any anti-slip texture, but the contact area with the ice is much larger than that of a real skate, so it is relatively more stable than a skate, but easier to use on the ice than ordinary sports shoes in the previous life. slide.
Su Qingluan thought that there were no skates for her to play with right now, so she simply enjoyed "sole skating" like this.
After receiving Sister's permission and seeing that she was gliding very much, the two little guys immediately lost their footing and were eager to play on the ice.
Su Qingluan turned to look at them: "Don't be afraid of wrestling, but when wrestling, you have to lie forward and don't tilt your head back!" Although the younger brother and sister now wear thick winter hats on their heads, and the children's bones are soft, It's not that easy to break, but Su Qingluan is still very cautious.
"You must lie forward on the ice, yes, body forward!" Su Qingluan looked at his younger siblings.
In fact, she originally wanted to tell her in advance, but whether it was her own experience or other people's experiences and lessons, it all showed one thing: no matter how many times she told her in advance, once she encountered an emergency, her body would really fall. , all the warnings and key points were completely forgotten.
The only useful method is that from the moment they get on the ice, Su Qingluan will let his younger brother and younger sister wrestle more, and constantly correct their postures until both of them get used to the "correct wrestling posture."
Although they didn’t know why they had to “lye forward”, Su Qingluan’s words could now be obeyed unconditionally by their younger brother and sister, so the two little guys listened to their sister’s request and stood on the ice and slightly bent forward. Make sure that even if you fall down, you will lie forward.
The same goes for Su Guangfu and Yang. But the two of them were adults after all, and they had many worries and were not that playful. When Su Xuanhe and Su Xueyan started to laugh and play, but because they could not control the movement of their legs well, they slipped and fell one after another. I can only be afraid to move easily.
After all, they are more afraid of falling than children - not only because older people's fractures will be more serious, but also because they are afraid of causing trouble for their children.
So let alone playing on the ice, Su Guangfu and Yang didn't even dare to take off their spikes. They kept their eyes on the three children, always ready to rush over if something unexpected happened to the three children.
Of course, Su Qingluan wasn't just playing. After all, she was not a real girl of thirteen or fourteen years old, so after playing for two rounds, she looked at her brother and sister.
"Sister, how do you skate? I want to skate too!" After falling three times in a row, Su Xueyan wanted to cheat and simply sat on the ice and couldn't get up.
Su Qingluan smiled and said: "You haven't learned how to use your strength yet - look, your brother has done it well."
Su Xueyan turned her head when she heard this and found that although Su Xuanhe was still slipping and swaying, he could at least slide a certain distance on his own feet.
Children are just afraid of comparisons. The little girl who was sitting on the ground and was fooling around saw Brother Hui slipping and quickly got up and grabbed Su Qingluan's sleeves: "Sister, please teach me!"
