Burning Immortal Stone, isn't used as fuel for refining Immortal Artifacts but is... the charcoal of the Immortal World. It sounds a bit embarrassing, but providing Burning Immortal Stone for heating to every immortal in the Heaven Realm is one of the few benefits available to ordinary immortals.
That's because these Burning Immortal Stones can save lives at critical moments!
Many cultivators in the Lower Realm yearn for Ascension, thinking that afterwards, they would be carefree and live forever. In the Heaven Realm, if the Immortal and Divine Clans did not fight openly or secretly, if the Antiverse didn't cause trouble from time to time, and if there was nothing to pursue after Ascension, this kind of state might actually be possible. However, under the complex situation in the Heaven Realm, it's impossible for any Immortal to live peacefully.
