Gravel was scattered on the ground, covered with a thick layer of snow.
The two old men were injured and couldn't climb up for a long time. The snow on the rocks was slippery and icy.
The old man tried for a long time but still couldn't get through. He waved his hands breathlessly and said, "Don't save me, I can't get through!"
"Yeah, just give us something to eat and drink. We're really cold and hungry."
The old man was thrown out and fell heavily. Qin Zhenbei looked at the height of the gravel.
"Don't worry, I'm here to save you!" he said as he raised his legs and prepared to climb onto the rubble.
But after a few tries, he slid down and couldn't find any leverage to climb up.
Even if I could get through, the two old people would not be able to get through.
It's freezing cold, and I'm afraid they won't be able to bear it if they continue to delay the afternoon.
These gravels are very heavy and difficult to move without tools and large vehicles.
Seeing that she was at a loss, Jiang Manyue took out two bags of salt from her bag: "Don't worry, leave it to me!"
Several people watched as she opened the salt and sprinkled it on top of the gravel.
"Man Yue, what are you doing?" Qin Zhenbei couldn't believe it.
"Yeah, what's the use of spreading salt on the ground?"
Soon something surprising happened to them. The frozen snow on the ground began to melt.
Use the tool to shovel lightly and clean it up immediately.
"That's amazing! How did you know this? Salt can actually melt ice and snow."
Qin Zhenbei smiled and nodded: "It's you again, no wonder you brought so much salt with you when you went out."
Salt melts snow because it coats the surface of the snow with a thin layer of salt solution.
Anti-skid chains and salt will be often used in disaster relief in the future.
After her operation, Qin Zhenbei and Officer Wang successfully climbed over the rubble.
The two injured elderly people were quickly rescued and rushed into the car.
Unexpectedly, they saved three people in one go, but the bus in front of them overturned and their lives were in danger.
