Salt Frostcriminal Investigation

A city's blood is rusting, and truth is the only antidote. In the cold winter of 2025, criminal investigation team leader Yu Yan took over a case of bizarre poisoning of a pregnant woman, but found breathing metal crystals under the skin of the deceased. A gold-plated pen engraved with plum blossoms and a string of quality inspection numbers spanning thirty years led her into the unsolved mystery of the scene where her mother fell - in the yellowed experimental diary, every date stained by tears replayed today's tragedy. When the salt frost in the water supply network began to eat away at the newborn's pupils, and when his own DNA became a red mark in the criminal database, Yu Yan discovered: Forensic doctor Lu Chen's agarwood beads absorb the memory of the deceased Environmental expert Lin Shu's tattoos hide the coordinates of the city's underground lifeline The lullaby my mother sang before she died was actually the password to reverse the countdown. Deep in the corroded pipes, the sins of 1995 are gushing out with water pressure. Yu Yan must peel away the truth from the bloody puzzle before the clock hand points to the seventh gear - pointing the police's gun at his mother's tombstone, or using a scalpel to cut open his gradually metalized heart. When the salt crystals in the quenching pool boiled for the last time, some people chose to lie to extend their lives, and she wanted the truth to crystallize in blue blood. ——Have you heard the whimpering of the underground pipe network? The countdown has begun.
