If one did the math, thousands of years had passed since the time of the world's transformation. The changes in the outside world were changing day by day during these thousands of years. New changes would occur rapidly almost every few decades.
The earth had changed in just a few thousand years. Productivity erupted in the outside world. Although people were still oppressed, their lives had already changed drastically. The productivity growth brought about changes in other aspects, which also changed the outside world into a different appearance.
At this moment, most of the Primogenitor World had an appearance familiar to Chen Heng. Presumably, in a few more years, if this world continued to develop, it would become a familiar appearance to Chen Heng.
However, everything was still stagnant in the territory of the God of Shadow and the God of Nature. This showed a similar appearance to when the bloodline primogenitor still existed.
