I had to admit, even though Energy Cores were outrageously expensive—the very definition of a luxury item—using them felt absolutely incredible.
When cultivating with one of these things in hand, as long as one's understanding of 'Law' and 'the Dao' was deep enough, one's Cultivation could advance by leaps and bounds.

On the twelfth day, Li Chang'an had completely absorbed the first Energy Core. His Cultivation broke through the threshold to Tier Three, restoring him to the peak strength he had possessed in the Great Derivation World.
But Li Chang'an didn't stop there. He spent another ten days or so absorbing most of the energy from the second Tier Three core.
