The number of all manner of geniuses that would emerge by then would be calculated in millions and tens of millions.
If the rate were to be calculated according to the base population of Huaxia, those who had once been considered geniuses in previous eras would have been considered common people in the era to come.
Only those who were the best among the best, the ones at the very cutting edge, could be considered geniuses by then.
All of that raised the bar of what was considered "genius" by several orders of magnitude one way or another.
The reason was simple—there were too many people around by then. People might have been considering themselves geniuses because they were only a handful of them found in any clan or sect out there.
