The neon-studded Linjiang City looks like a modern city with booming economy on the surface, but underneath lies an intricate network of forces. Lin Yan, an orphan who carries the secret of his family's downfall, wanders around the market and accidentally gets involved in a whirlpool of underworld power reshuffle. He looks gentle, but there is an untamed edge hidden in his eyes, and he uses his amazing resilience to carve a way out amidst the lights and shadows of swords.
Su Qingye, who was born into a noble family but was rebellious, accidentally met Lin Yan in a chaotic street conflict. She carries the idealism of an intellectual, but in the process of getting closer to Lin Yan, she glimpses the laws of survival outside the order, and gradually discovers the secret involvement of her family and the underworld.
When Lin Yan's road to revenge intersects with Su Qingye's family dilemma, when the rules of the white world collide with the iron laws of the underworld, they pull each other in the shadow of Linjiang City, becoming each other's weakness and armor to move forward. This is not a simple feud, but a struggle that is carried by the torrent of the times - some people are lost in power, while others persevere in desperate situations, and Lin Yan and Su Qingye will eventually write their own unique urban legend in the tempering of blood and fire.
