He had never seen earth-vein flames so endlessly vital and extraordinarily powerful.
So... Chengyuan had melted down the Heavenly Foundation Stone!
He intended to use the Heavenly Foundation Stone's miraculous properties to forge a Heavenly Foundation Dao Robe. After all, it possessed remarkably powerful stabilizing and restorative effects, could shield Heavenly Secrets, and came wreathed in Dao resonance.
It would not be an exaggeration to say that wearing this Dao robe meant cultivating without pause.
After seeking Chen Xun's approval, Chengyuan got to work...
His attainments in artifact forging were quite exceptional, far beyond those halfway-cultivators like Chen Xun and the others.

His existing forging techniques were no longer suitable. Everything he forged was scrap... Wearing it might even risk an exploding body.
Chengyuan's expression was unfathomable, without the slightest ripple.
