Cultivators used mana to increase the power behind their strikes during a fight, which was why an individual with a Silver core would be far stronger than a Bronze core, as the quantity and quality of their mana, along with the medium for that mana to be channelled across the body, was different.
Silver core was fundamentally of better quality than a Bronze core, which resulted in the mana being effectively used within the body.
The speed at which it was channelled through the mana meridians, along with the intensity with which the individual could use mana in a particular part of his body, depended on the rank of the mana core.
But... that was not the only benefit of having a higher-ranked core.
With every rank up, along with an increase in the mana reserves and the quality of the mana core, the individuals also benefitted with an increase to their baseline physical strength.
Now... every race had their own advantage from birth relating to their physiques.
