"This matter isn't really a secret."
"Once, when I accompanied my father to the Holy City to receive a legacy, I heard a royal Dragon say that during the advancement to Legendary level to comprehend the Law Origin, a Spiritual Imprint will be left within it. If it's a super strong entity, after death, when the Law Origin dissipates, the residual power will merge into the corpse, and the Spiritual Imprint remains. Later, by spending a great cost to awaken the Spiritual Imprint within the corpse, it can revive the strong from death."
"The ancient ruler of the Frost Giant race was awakened and revived by their tribe."
"Even though the awakened revival sees a significant decline in strength, it would take a long time to regain peak combat power. However, the time imprint hasn't been obliterated after tens of thousands of years. That ancient ruler, even if not Epic, must have comprehended some Power of Time to achieve spiritual immortality."
