Comments of chapter undefined of Practicing Basic Sorcery for Billions of Times Made Me Invincible

It feels like theirs two authors and they made an outline for the story and then they wrote the differnt parts wothout talking to eachother. Like how does the eastern emperor die 500 years ago when people were going to the east every 10K years to try and get the stone to become the new emperor? What happened to those same people calling the east a wasteland and barren and now the east apparently these guys didn’t know that all the experts died 500 years ago? Theirs all sorts of other flaws as well like magus’s only live 1k years apparently and yet the stage below them has guys that are 2.5k years old.
