Xiluo recalled her previous words, and her face burned with embarrassment.
She clenched her fingers tightly.
Ying Zijin actually understands Alchemy!
"Indeed, it's not much of a challenge." Xiluo slowly exhaled a breath, sneering, "Since there's no challenge, let's start crafting the Philosopher's Stone now."
"In front of everyone, let's see who crafts the Philosopher's Stone with higher quality!"
Turning Stone into Gold is indeed the most basic of Alchemy, even an Alchemy Apprentice can do it.
But the Philosopher's Stone is not something anyone can craft.
It's just a bottle of potion, maybe Ying Zijin bought it online.
But if it's done on the spot, everything will be exposed.
Sinai's expression changed: "The Philosopher's Stone..."
She had certainly heard of the Philosopher's Stone.
Simply put, the Philosopher's Stone is the so-called "Elixir of Immortality."
Of course, absolute immortality doesn't exist; the Philosopher's Stone merely extends human lifespan.
