Identity of the protagonist: Lin Su, a cultural relic restorer in the 21st century, possesses the rare ability of "empathy" - he can read the strong emotions remaining on ancient objects when he touches them. While repairing Ming Dynasty blue and white porcelain, he was involved in the cracks of Shixu and became a "Shixu restorer" who traveled through the ages.
