"Devouring cultivators, especially powerful ones, is the correct method for a divine artifact to progress,"
In a moment of realization, Jiang Chen understood how a divine artifact should advance. The more cultivators it devoured and the stronger they were, the faster the divine artifact would advance.
Devour everything to nourish oneself.
However, indiscriminate killing violated Heavenly Dao. While Jiang Chen understood the method for a divine artifact to advance quickly, he would not abuse this ability to devour lives indiscriminately.
Speaking of devouring lives, Jiang Chen already had a better choice—Fierce Beasts. As far as the Prehistoric World is concerned, Fierce Beasts were harmful and brought no benefits.
Hunting Fierce Beasts would not only avoid condemnation from Heavenly Dao but would also be rewarded by Heavenly Dao, earning merit and fate's protection.
