Teacher Su, who appears to be the gentlest teacher in Chunhua Kindergarten, is actually the backbone of the underworld's "Cultural Relics Pursuit Department", dedicated to tracking down national treasures that have been lost overseas and carry China's destiny. Her new mission was to get close to a suspicious rich father, but she was "discovered" on the spot by his mixed-race son who could see "ghostly lights". Since then, her daily life has changed to taking her children and reading the picture book "Relics Bringing Home" during the day, identifying treasures and fighting smuggling syndicates at night, and having to work part-time to educate the villain's father and son on patriotism. When hundreds of cultural relics resonated with her at the final auction, Su Tang knew that this month's KPI was stable.
