Don't Ask About Longevity

Everyone desires immortality, but does anyone really live forever? The former Emperors of Qin and Han Dynasty are now no more than withered bones in their tombs. Those who use evil magic to live forever will seize their souls and refine their souls, but will eventually be devoured by their souls; those who drink blood to seek longevity will not be able to escape the blood debt that demands their lives. On the road to eternal life, there is no way back, only dead bones.
