In the chaotic grassroots era where power is changing and wars are raging, the urban scoundrel Qin Sanliu accidentally gets involved in a palace coup and gets acquainted with the strange woman Liu Xiaosui, the sinister bachelor Bai Shaotang, and the loyal but cute Niu Mao Dan. In a world of chaos, powerful forces, and heroes emerging in large numbers, this group of little people have experienced growth and transformation from being trapped by fate and struggling for survival, to smiling in the face of the tide, fighting hand in hand, to fighting swords in the world, and writing legends.

Although they went their separate ways, they had no regrets about their youth.
