Light blue, dark blue, light purple, dark purple...
This is the distinction between different intensities of Reverse Power.
The deeper the color, the stronger the Reverse Power one possesses.
In fact, one does not need to refine Reverse Power to dark purple in order to impact the Reverse Life Mirror.
Generally speaking, many cultivators, when first comprehending Reverse Power, often maintain the Reverse Power within their Divine Sea in a state of light blue or dark blue.
Because only in this way, the Divine Tribulation summoned during the impact on the Reverse Life Mirror will not be so terrifying.
After all, once Reverse Power is refined to purple, the terrifying degree of the summoned Divine Tribulation can be lethal, and many people are unwilling to take this risk.
