Core world view:
The universe is not single, but composed of countless "epochs" superimposed. Each era is a complete world (such as Gaowu Daqin, Mysterious Steam, Fairy and Demon Chaos, etc.). After the end of the era, it will turn into "dead ashes" and sink to the bottom of the river of time. The protagonist can physically cross the river of time, enter these dead or collapsing eras, steal their core laws, and prove the truth in this world.
