One month later.

Fang Yuan completed the last spell, embedding the specially prepared restriction into the Outer Pill. He let out a long breath. As long as this specific spell was embedded, the Purple Lustre Outer Pill would have a backdoor. By activating the spell, Fang Yuan could directly retrieve the Purple Lustre Outer Pill into his hands, regardless of whether it had been refined by others.

With a passing thought, Fang Yuan looked towards the earth fire. Currently, under the refinement of the earth fire, the essence of all the treasures had merged into a round, purplish pill.

The pill was the size of a soybean, shimmering with a purple glow, covering the entire spectrum of colors like the purple haze in the sky.

"Purple Lustre Outer Pill, almost there!"

Watching as the Purple Lustre Outer Pill became more complete under the scorching of the earth fire, Fang Yuan's eyes showed a hint of joy.
