Burning the Essence of Life!
This is a reckless act that almost all species resort to at moments of utter hopelessness.
Even if a species does burn the Essence of Life, it would never do so as intensely as the Northern Cold Wolf Master, for no one truly wishes to fall in the realm of Heaven and Earth.
Even if living in disgrace, one still desires to continue living.
After all, only while alive can there be all possibilities.
And beings that reach the level of the Wolf Master, as long as they possess a trace of consciousness, spirituality, and a mere tenth of the Essence of Life, can find a Blessed Land in Heaven and Earth to sleep and wait for the next era's resurrection.
So even though the Deep Sea Blue Dragon and Mysterious Sea Monster were vocally intent on completely killing the Northern Cold Wolf Master, they only wished to cut off this current incarnation of the Northern Cold Wolf Master.
