In the third year of Xuanhe's reign, thirteen red lanterns floated down the Bianhe River.
Under each lamp, an embroidered shoe hangs.
Kaifeng Prefecture's head catcher Lu Chen took over the case, but he didn't know that he was entering a dead end that spanned twenty years.
When he followed the medicinal fragrance of "Angelica" and returned to his hometown that was washed by blood;
When he saw the strange woman who woke up from the poison and called him "brother";
When the emperor deep in the palace placed a Pisces jade pendant in his palm——
Only then did he understand:
It's not the demons who massacre the village, it's the human heart.
It's not the poison that kills people, it's longevity.
And he must make a choice before the blood moon rises:
Hand over your biological sister and refine the elixir of life?
Or should we make the final bet with this cannibalistic world?
Suspense reasoning, the plot does not drag on
