On Christmas Day, the already disaster-stricken human race received new tragic news – a meteorite with a diameter of over ten kilometres was about to collide with the Earth. Governments around the world suppressed the news to avoid panic, but as the meteorite gradually approached, the news still spread like wildfire. People began to panic-buy supplies. As a web writer with a wealth of imagination and logical thinking, Chen Xin decided to dig for a shelter while stocking up on supplies. He knows that the disaster caused by the meteorite impact will be devastating. From the earthquake and high temperatures caused by the violent impact, to the subsequent global fires, tsunamis, and extreme cold, each disaster is deadly enough. While countries are actively responding and proposing various plans to intercept the meteorite, Chen Xin is also preparing for his own survival.
