The next part of the story could vary a great deal. In some cases, the boy might be unconscious when he's pulled from the water. People around would try to warm him up gradually. The medical staff at the hospital would then work on stabilizing his condition. They'd check for things like frostbite too. After that, it would be a long recovery process, both physically and perhaps even mentally, as it's a very traumatic experience.
Since we don't have more details, it could be in a small local pond in a European village during a particularly cold winter. There are also places in Russia where such an incident might occur. In fact, anywhere that has cold enough weather to freeze water bodies and where people might be near them, like skating on the ice or walking across, could be the location of this true story.
It's a tale of a brave kid who was playing near a frozen lake and accidentally stepped on thin ice. Luckily, he was rescued in time.
He might have been seriously injured. Falling five stories is a long way and the impact could have caused broken bones, internal bleeding or even be fatal.
He might have been seriously injured or unfortunately died. Falling nine stories is a very long distance and the impact on the ground would be extremely severe.
There could be many reasons for his fall. Maybe he was on a balcony and lost his balance. Or perhaps there was some sort of accident in the building that caused him to fall through a window or railing. It's also possible that he was trying to escape from something or someone and in the rush, he fell. Whatever the reason, it's a very tragic situation.
It was a miracle. The boy managed to stay calm and find a way to get out of the icy water before it was too late.
Again, without more details, it's impossible to know for sure. He could have had a life - changing experience. Maybe he got into an argument with the person he was standing next to and it led to a new friendship or feud.
In the next three days, a lot could happen. If it's related to nature, you might witness the blooming of some flowers if it's the right season. Socially, there could be a small gathering in your community that you end up enjoying. At work or school, there could be a project or assignment that turns out to be really interesting and fulfilling.
He might have been seriously injured or even died. Falling from such a height is extremely dangerous.
Perhaps he'll discover an ancient Martian civilization. There could be old structures, artifacts, and knowledge that has been long forgotten on the surface. He could become the key to unlocking the secrets of this lost civilization, or he could accidentally set off some sort of mechanism that has been dormant for ages, which could lead to various consequences, either good or bad.
