The Red Seal on the Door
On the morning the refuge is officially marked for forced sale, Lin Yue turns public panic into a temporary hold and uses his damaged advantage to read a hidden correction in an old repair ledger. That measurable resonance leads him and Aunt Shun to a concealed cavity in the back hall, where they recover the first buried record. Before he can read it, the seal-responsive structure wakes and exposes that the sale notice was hiding more than debt—while the strain and sudden noise make the refuge visible to anyone watching.
