there was an earthquake in your city.The high-rise building in which you lived was completely destroyed.everything happened so quickly that many people were injured under the debris.you too.when you came to, you realized that your leg was pressed by a fragment, and it seems that it was pierced by a metal rod.your body was terribly painful.you don't even know how long lay there.there was no strength and hope.suddenly, you hear a loud male voice -is there anyone here!?
