I can picture it, the dusted corridors, stone walls lined with scrolls that crackle with the scent of forgotten ink. If the texts hold the precise measurements, the alloy ratios, the fire‑treatments, we could rebuild that craft. But it’s not enough to stumble upon a relic; we must decipher the language, test the theories, and accept that the original artisans had secrets we’ll never fully grasp. Still, a hidden library in a mountain is the kind of discovery that could shift our entire understanding of that lost art.
