But the Mystic Sect Saints and Witch Clan Saints are better; they can all see the signs of emergence. However, the Human Race Saints alone show no signs of appearing so far.
Jiang Chen set the standard too high, requiring a Human Race Saint to achieve sainthood through merit, an almost impossible feat to accomplish.
Given the current state of Heaven and Earth, gaining enough merit to become a saint is clearly not feasible just by doing good deeds. Only one path remains: defeat the Chaos Demigod and offer it to the Prehistoric World.
But if one has the ability to defeat a Chaos Demigod, what use is a sacred position? It's contradictory.
Thus, relying on merit to become a saint has become nearly impossible.
Jiang Chen's difficulty lies here. At the time, he didn't think much about it, only believing this method could inspire all beings to do good, and thus he set such a requirement.
