In a world filled with evil spirits, human life is as light as a feather, and all living beings are devastated. The young man Ling Yun walked in this dark land with a long tempered sword in his arms. The battle on the banks of the Wei River strengthened his determination to change the world. From fighting a half-human, half-snake monster to seeing through the tricks of a monster disguised as an old woman, he relied on his extraordinary courage and skill to escape from the evil clutches time and time again.
The tragedy on the snowy night three years ago was an indelible pain in his heart, and it also became the source of motivation for him to slay demons. A knife and a talisman supported him on his long journey. There are more ferocious monsters and unknown dangers on the road ahead, but the light in Ling Yun's eyes never goes out. He firmly believes that even if the world is full of evil spirits, as long as he has a knife in his hand and light in his heart, he can one day split this chaos and restore clarity to the world. This is a legend written by a young man with a knife, and it is also a heroic song about finding light in the darkness.
