The man on night duty suddenly noticed a ghostly figure behind the canvas, leaving him petrified. Immediately, his colleague, Brother Qiang, shouted loudly, and out of security concerns, they reluctantly followed. However, they never expected the woman in the red dress to instantly jump off the deck.

Strangely, despite the person's size, not a single splash of water emerged when they jumped, as if they silently disappeared into the water. Brother Qiang's expression turned into a meme-worthy expression of shock. The following day, the dock was crowded with curious onlookers. It turned out that the local tea merchant, who operated outside the countryside, had unexpectedly died on their own tea cargo ship the previous night. Meanwhile, Brother Qiang, visibly shaken, claimed that it was the work of his daughter, who not only had long hair but also long legs.

The local magistrate sought the assistance of a young man standing before him to uncover the truth. However, one should never underestimate this young man, as he was none other than the renowned forensic examiner, Song Ci. If there was anything suspicious, it was the scattered tea leaves in the countryside's room and the untouched freshly brewed tea that had gone cold.

Even more perplexing was the fact that the murderer, having already killed, could have escaped. So why stage this scattered crime scene? Clearly, Song Ci had encountered a mastermind, but the young aristocrat Zhao had his own perspective. If Brother Qiang and his companion were the culprits, and the story about the vengeful female ghost was merely a fabrication, then everything would make sense.

However, Song Ci firmly believed that the real culprit was someone else entirely. If the motive was financial gain, the perpetrator would have taken the valuables from the ship and disappeared, without the need to return and report the crime, essentially walking into a trap. Furthermore, traces of the woman in the red dress appeared in the prison cell, and even the helmsman, who navigated the ship at night, fell victim to a sinister attack. These developments added more layers of mystery to the already enigmatic case, putting young Song Ci under immense pressure once again.
