As for whether Qing Feng's strength in reality would grow to the extent that it could rival a cultivator at the Golden Core Middle Stage, He Song had no certainty in his heart.
However, according to He Songzhen's actual thoughts, this speculation was probably not far off the mark.
Even if Qing Feng's strength did not rapidly reach the level of the Golden Core Middle Stage in subsequent enhancements,
it was definitely not far behind.
Besides that,
regarding the strength of his other puppet, Mingyue,
since He Song had always not intervened much with Mingyue and hadn't provided any precious materials,
as a result, Mingyue's strength, compared to Qing Feng, was indeed much less.
However, during the time He Songzhen was in seclusive cultivation, Mingyue's strength, just like Qing Feng's, was continuously improving.
It's just that, since He Songzhen did not infuse any precious materials into it, Mingyue's strength growth actually couldn't keep up with Qing Feng's.
