Doomsday Crisis

A year ago, a shadow of light shot out of the Mariana Trench into the sky. Six months ago, a certain country announced at a press conference that it had developed a medicine that could increase physical strength by 10% after use without any side effects. Ten days ago, a light emitted from the Mariana Trench again, spreading like a firework in the sky, and then it rained continuously for five days in a country on a small island.
