Back when Yunfan acquired the "Fighting Star Fire Scripture", it included secret manuals for both alchemy and weapon forging.
In this world, magical treasures were strictly graded into Heaven, Earth, Mysterious, and Yellow tiers, corresponding directly to the cultivation levels of Qi refiners.
Even more astonishingly, the scripture also recorded methods for forging magical treasures that surpassed the Heaven tier, though Yunfan appeared completely calm on the surface. Forging divine-level treasures not only required materials that were exceedingly scarce, but the process also took an immensely long time, often measured in years.
