Obliteration Storm Calamity, Decaying Green Essence.
The Obliteration Storm Calamity was gathered by Li Fan from the remnants of damaged Immortal Instruments within the Xuanhuang World. Any surviving Immortal Instruments in the world, more or less, contained traces akin to the Immeasurable Mirror.
As for Decaying Green Essence, it was initially discovered by Li Fan on the Thousand-Eyes Barren God. It burns away the foundational vitality that sustains existence, with a terrifying destructive power rivaling that of the Obliteration Storm Calamity.
The Obliteration Storm Calamity is a specialized transformation of the Path-obliterating Calamity wrought upon Immortal Instruments, while the Decaying Green Essence specifically targets Immortal Servants!
