Su Ci, a materials prodigy, accidentally traveled through time and became an orphan in the declining Liulifang. In order to revive the family business, she worked hard and finally fired a secret glaze that contained the "jade spirit light" - its color changed at will, from intense blue to deceptive red. This "glazed heart glass rhyme" was favored by the nobles in the palace and became a carrier of secret messages to convey their feelings. Su Ci also used a unique "light-based mapping" method to draw patterns on the glass that could only be interpreted by a specific "spiritual mirror", and was involved in the undercurrent of the intelligence war. When the enemy's protégé He Lianzhao was on the verge of death for "stealing secrets," Su Ci risked everything and joined forces to break the situation, using the secret of the "Jade Soul" as a bargaining chip. From the strife in the court to the game between the two countries, under the bright light of colored glaze, it is the game of emotions and the pinnacle of skills. It is also the legendary book in which Su Ci used colored glaze as a pen to write a peace covenant and reflect the hearts of the world's lovers.
