During the Dajing period, the imperial court was in disarray, the empress dowager lowered the curtains, and wherever the "rain bell" sounded, a loyal and good person must die.
The royal guard Xiao Changfeng (male protagonist) performed his duties faithfully, but he suffered injustice due to a sudden Caoyin robbery. He fell from the clouds and was demoted to Haichang County in the south of the Yangtze River where the people were living in poverty. Faced with the oppression of the powerful and the sorrow of the people, he did not choose to indulge in revenge, but determined to "use the law as a sword to cut off all injustices in the world."
In Haichang, he met Sang Ruo (the heroine), a talented woman from a family of imperial doctors. The two of them are both civil and military, starting from investigating the "granary arson case" and working together to fight against the intertwined evil forces and the mysterious organization "Yulinling". This is a road full of thorns: close friends betrayed, imprisoned, and even wanted by the court. But Xiao Changfeng never wavered - he not only wanted to wash away his grievances, but also wanted to reshape this muddy world.
From the captain of a county to the most respected minister, from fighting alone to gathering the hearts of the people all over the world, Xiao Changfeng used his wisdom and iron bones to prove that the real strong man does not break other people's swords in the wind and rain, but straightens his own backbone in the rainstorm. When the fog clears and the wind breaks at dawn, the once frightening "rain bell" will eventually turn into a crisp wind chime that protects thousands of families.
