"Evolution fluid."
After inspecting it for a moment, Shi Lan unfurled a sliver of her domain and drew the evolution fluid in her hand into her body.
A vast surge of life energy blossomed within her. In just a few breaths, it flowed into every limb and bone. Perhaps because her body had already transformed to an extraordinarily high level, the vial brought no noticeable change—only replenishing some of her life energy.
This life energy carried a strong aura of living souls. Clearly, some of the ingredients had been extracted directly from living beings.
A flicker of shock crossed Shi Lan's eyes. In a sense, this vial of evolution fluid had extended her lifespan.
Not by much—only around a hundred years—but lifespan was tied to one's cultivation. Without a breakthrough, it was difficult to raise its upper limit. Even immortal medicines that prolonged life had their limits.
Many spirit pills that could extend an ordinary person's life were utterly useless to high-level powerhouses. A treasure capable of extending the lifespan of someone at her level was already extraordinarily rare.
And this vial was only B-grade. The highest grade of evolution fluid was S, two whole levels above B. Clearly, this was nowhere near the true limit of the Sarovina Interstellar Federation.
"Can this fluid be mass-produced?"
Suppressing her shock, Shi Lan turned to Aiden. If this evolution fluid went into mass production, its effects would accumulate over time. For top powerhouses nearing the end of their lifespan, it would be a literal lifeline.
"If the trials go well, mass production and distribution are only a matter of time."
Aiden nodded, then furrowed his brow.
"But it'll take at least eighty years for it to be released and reach this star region. The Federation headquarters may already have the capacity to
