Charles IX: Return of the Hourglass

An ordinary trip to Saishang Lake City planted unusual seeds in the hearts of the DODO adventure team. After returning home, mysterious "antique" tokens that perfectly match the identity in the dream - bronze tokens, rat whisker pens, obsidian amulets, stone military tokens, and even Charlie's new collar - are like lingering ghosts, quietly appearing at everyone's doorstep. The obscure mottos on the note hint at the unfinished mission. However, the peaceful campus life was shattered by reality. In the physics class, Duo Duo's distraction and dropped copper seals led to the teacher's ruthless ridicule: "You are not on the right track! Stop your detective dream as soon as possible!" Before the frustration dissipated, an even more frightening figure knocked on the door - "Ghost Princess" Yin Ling, with inhuman eyes that saw everything, coldly exposed that all "gifts" were fakes with superb skills. The flaws on her fingertips (perfect mechanical cutting marks, cinnabar mixed with bone phosphorus powder, and scratches from power tools) and the dark blue velvet knot at her waist that was the same color as the lining of all tokens pushed the mystery deeper into the vortex.
