Restart the Civilization of Cultivating Immortals Starting from the Tribe Leader

Take the imperial examination and then become the leader of a primitive tribe? Xiao Ge once traveled through time and became the leader of a group of primitive people. Everything was waiting for improvement, and everything had to be built by him. Totems, jade talismans, sacrifices, giant trees, monsters, aliens... Xiao Ge originally thought this was an ordinary aura world, but as time passed, he discovered the secrets of this land's past. The dilapidated and desolate ruins can provide a glimpse of the prosperity of the past, and the relics picked up from time to time can capture the memory of the previous generation's civilization... Has this world ever been destroyed? Is it already post-apocalyptic? "Return to the peak of the human race! Realize the renaissance of the human race!" "From now on, let humanity be great again!"
