Although due to an accident, Divine Thought reached the Core Formation Level ahead of others, in the Earth Desolate Mountain Range, no one in the Purple Mansion could probably rival him.
But this position of being the first is relative, as in the other two mountain ranges, and even in the Taiyin Profound Celestial Sect, which commands the Three Desolate Mountain Ranges, there is certainly not only one Golden Core Cultivator.
More importantly, Zheng Yi is really too young, having transitioned from the Righteous Dao to Demon Dao, in just a few decades, his Divine Soul has already equated to the level of Core Formation.
Being young is both Zheng Yi's advantage and his shortcoming.
