from the information we have, the primeval universe is divided into two eras. The first era is the previous era, and we are now in the second era!
in the first era, all living beings lived on the vast and boundless primeval mainland. The cultivation conditions back then were far from what we have now. Hence, it was a true Golden Age for cultivation and there were countless experts. Hence, there were also many treasures that were far from what we have now.
after that, even when the primal Chaos continent collapsed and the first era headed towards destruction, all the experts disappeared, leaving only the universe junkyard behind. However, the universe junkyard still contained countless opportunities and treasure lands. Many of these treasure lands even possessed endless temptations for existences that surpassed the divine Lord realm!
