The birth and development of civilization itself is a process from nonexistence to existence, an evolution from the initial spark of civilization to a continuously thriving and unbroken one. This requires not only the guidance of the mighty but also the sedimentation of time to slowly accumulate.
Even though Pei Xuanjing created the realm of Longevity World, a Small Thousand World, in reality, it was still far from the mark.
Within this world were some Innate Gods who were born at the beginning and some sentient beings that came into existence later. Despite the significant power these beings possessed, they were far from forming a real civilization. Or rather, they were incapable of bearing Pei Xuanjing's Dao; their civilization was too weak to bring much enlightenment to Pei Xuanjing.
