Plague is a book published by North United Publishing Media (Group) Co., Ltd. and Wanjuan Publishing Company from June 5438 to February 2009. The writer is Zhou Dedong. This book is about a saline-alkali land, overgrown with weeds, full of dead blisters of all sizes and grotesque willows, which is very desolate. Those blisters are dark green, because they don't flow all the year round, and there are no fish in them, which may breed strange creatures that humans don't understand. It is said that someone once saw a man's body there and couldn't see his face clearly, because his body was hidden in a dark green blister, only his feet were exposed, black and rotten, and his poor bones were exposed.
