The most popular item in the northern kingdom which had stolen the limelight for the past year was none other than the Colored Glass of the Heavenly Palace.
What was the Colored Glass of Heavenly Palace?
To put it plainly, it was just glass, or rather, glass with impurities that appeared opaque and slightly iridescent.
Because of the grand backstory Gu Xin had made up for the glass, claiming that glass had descended to earth alongside a golden phoenix, and that each piece was beautiful, glass was given the fancy name Colored Glass of Heavenly Palace, implying that it was a treasure from the Heavenly Palace.
