It's raining at night in Lincheng and the wind is blowing in the alley.
Shen Jilan was holding a red lacquered wooden box that contained a secret, and was rescued by Gu Xingzhi, a young marshal from the Northland, in the rain. He protected her with a token, but she heard her own heartbeat under his cloak.
The flames of war, intrigues and misunderstandings pushed the two away time and time again. Until the wind chimes of Wanghai Tower rang again, Gu Xingzhi monologued at the beach, entrusting half his life's forbearance and love to Chaosheng.
A token, an old lamp, from the rainy night to the seaside, can they keep the everlasting "embers" in their hearts amidst the light and shadow of swords?
