I don’t know when the ice formed, I believe it must have been earlier than I discovered this time.

Because there are already many signs of damage on the lake.

The most eye-catching thing is a large ceramic vat, which was originally placed on top of the sewer shaft, but now it looks like it is sinking lazily, half of its body embedded in the ice, swaying.

There must have been a lot of ice in it too.

Next to it, there are many scattered ice cubes.

Those kids must be making an ice cave here again.

Sure enough, when I looked up, I saw a child holding a big log and knocking at a hole in the ice.

So, the ice-breaking began.

The efficiency of that wooden stick was really very low. The child had been knocking there all morning and only made a very small hole.

However, we can also see from this that the ice is not thin, about 5 to 7 centimeters thick, crystal clear, and the cross-section is very neat.

So I thought of the method I used during last winter vacation: hitting with rocks.

The biggest stone was naturally the pond without water under the lake. There were countless large and small stones piled neatly in it, some of which I could only just move.
