The Purple Cloud 紫云
A "Last Man" Classic! A world-encompassing purple cyanide cloud passes over Earth and annihilates all living creatures except Adam Jefferson. He embarks on an epic journey across a silent and devastated planet, an apocalyptic Robinson Crusoe traveling back from the Arctic where he survived the cloud. Upon his return to civilization he realizes that he is the sole survivor, and with no society to restrict him he becomes an all-powerful insanely destructive juggernaut in this post-apocalyptic world.
