Faced with the absurdly enormous mech before them, Little Knight showed not the slightest panic.
They had already experienced the intimidation of these massive monsters in a certain coastal cave.
And as a Vessel born of the hands of God and Void, made for battle, the same trick would never work on them twice.
Soulfire blazed in their eyes. From Little Knight's perspective, several crimson points of light dotted the massive machine.

At its core, it was an extremely efficient way of utilizing soul energy.
If white soul spells emphasized versatility that made them usable by anyone,
Spirit Thread emphasized finer control and comprehensive functionality branching out from a single point.
Abyss spells emphasized ultimate destruction through absolute lethality, manifesting malice toward the living.
Soulfire, then, was a way of using energy with maximum efficiency as its goal.
From a physics standpoint, the efficiency of any energy capable of producing a practical effect comprised useful and wasted portions.
In other words, η = E_total consumed/E_useful.
Yet Soulfire, the source of Lin Jin's power, was exceptionally unusual.
In theory, the way Soulfire consumed energy allowed its user to produce the greatest possible benefit at an almost perfectly optimized ratio.
Because losses existed, no energy in the world could be released with perfect, one-hundred-percent efficiency.
That was unavoidable, but Soulfire could approach that limit as closely as possible.
