In his bedroom, Zhao Zuo composed himself and opened the red-lacquered wooden box containing the Artifact Refining materials.
At the same time, he also placed the Black Flame Saber next to the Artifact Refining materials.
Once everything was ready, Zhao Zuo summoned the transparent panel and lightly tapped the "Advance" option.
A familiar gray light spread out, enveloping all the materials. The advancement materials for the Black Flame Saber were all from the Fire Series, and their characteristics were remarkably consistent: they all possessed fiery, combustible properties. A simple analysis was all it took for Zhao Zuo to conclude that this advancement would increase the temperature of the flames.
Within the gray light, flame-like patterns gradually appeared on the surface of the Black Flame Saber. Like a raging inferno, these patterns emanated a scorching aura.
