After all, the full-power strike unleashed by Qing Feng under his control was simply too immense.
According to He Song's estimation of the crater's size, Qing Feng's strength must have reached the late-stage Nascent Soul level.
Perhaps only a cultivator at the late-stage Nascent Soul level could create a crater as vast as the deep sea with one strike?
Such power, even if He Song were personally present, he probably couldn't produce earlier.
And the striking power of a middle-stage Nascent Soul cultivator likely surpasses that of an early-stage Nascent Soul practitioner.
But the size of this crater before him was just too large.
Based on He Song's guess,
if an early-stage Nascent Soul practitioner weren't quickly slain by a middle-stage Nascent Soul cultivator,
then the power unleashed by a middle-stage Nascent Soul cultivator would probably still fall short of Qing Feng's strike today.
