I Lived to the End of the Heavens

Clouds roll in and drift away, the sun sets and the moon rises. In his spare time, he waits for people, quietly watching the long river of time. In these myriad worlds, Ye Feng is a participant, a passerby, a legend, a joke... But whatever he may be, he will always be there, carrying the Great Way of Immortality within him. The worlds, however, may not be. He has watched life evolve from nothing, lived through the extinction of the dinosaurs, witnessed legends of immortal cultivation, and taken part in battles that destroyed worlds... Note: The story begins in the wuxia world of The Heaven Sword and Dragon Saber. The protagonist has no System missions and doesn't put on a show for no reason. He values caution above all. Also, he isn't forcibly entangled with characters from the original story.
