No time travel, no system, urban cultivation, macrocosm
The ancestral star is still there, but the ancestral land has long been beaten and disappeared!
Even if there is no glimmer of light, there are still a group of sages of the human race who lived and died in vain throughout the ages, using their own blood and bones to create the last piece of pure land for the human race!
Until a certain life, a certain sage and great master found his ancestral land in the endless river of time, and then opened a new chapter for our human race...
