After the Heavenly Demon King entered the Holy Tower, he immediately went into seclusion and took out the Purple Gourd, spewing out the Tri-color True Fire to begin refining the Purple Gourd!
This Purple Gourd was an innate spiritual gourd. Not only did it contain a universe within, but it could also be used as a cauldron. For instance, if herbs were placed inside, a mere flame would automatically refine them into elixirs, with a hundred percent success rate.
Moreover, the Purple Gourd was indestructible. He had tried countless times but failed to destroy it. Adding fire on the outside, especially with his Tri-color True Fire, made the temperature inside the gourd millions of times hotter than the sun.
Nothing inside the gourd could resist being melted; even the Undying Gold Body would be melted!
