In 2085 AD, alien fleets pierced the sky, lasers and artillery fire tore apart human defense lines, armies from various countries retreated steadily, and the earth became a hunting ground for alien creatures.
Ye Xu, an ordinary young man who hangs out in Internet cafes all day long and survives on instant noodles and games, managed to survive in the chaos of the city's fall.
