It has been raining in Jinling City for three years.
Ye Chi, the "Flowing Cloud Sword" who used to be famous in the world, is now just a blacksmith in the south corner of the city.
Until that rainy night, a seriously injured female Kipcha Division detective broke into his shop, carrying the same strange poison and a mysterious token from the old case three years ago.
The dusty sunken sword buzzed again, and the gap in the sword seemed to be waiting for the lost meteorite iron to heal.
When the intrigues of the imperial court intersect with the poisonous shadows of the Western Regions, and the former brothers reappear, he must find a bright path between revenge and protection.
As soon as the sinking water comes out, the sword rain rises; when the truth is clear, it will be a sunny day.
