Time Ruins: Tang Rusty Knife

[This book has no system and no rebirth] It is just a simple, humorous and obscene story about cyber cultivation and time travel that is not very serious. Time series management is not an official organization but a group of survivors who collect time and space fragments to repair the rifts in time and space. The protagonist Ye Tong traveled from modern times to modern times twenty years ago. While collecting time and space fragments, he discovered that behind the bustling city was a ruin. When he stood on the long river of time and cause and effect with a knife, he discovered that the destruction of the world was actually caused by his own time and space singularity, and his master was the driving force behind the whole thing.
