The old man nodded with a touch of emotion and said, "Indeed. Celestial energy is incomparably superior to the spiritual energy of the grotto-heavens."
"Breaking through from the Spirit Severing stage into the Infant Transformation Stage is far more difficult than one can imagine. Unless one possesses the extremely rare Infant Transformation Pill, the only other way to break through is by absorbing celestial energy."
"Back in ancient times, this naturally wasn't something to worry about. Once your cultivation reached Spirit Severing, you would naturally ascend to the Immortal Realm, where there is more than enough celestial energy to absorb, making breakthroughs a simple matter. But now... Spirit Severing cultivators can only try their luck in the four immortal realms if they want to break through."
