Deep in a dense forest. Dozens of martial artists surround a single woman. Every blade is pointed at her, and a heavy tension weighs down the forest. The woman looks at them indifferently, her sword resting across her shoulders. In the next moment. The sword slowly slides out of its scabbard. A single streak of red sword-light slashes across the forest. In an instant, trees fall and the earth splits. The martial artists collapse, spraying blood without even being able to resist. A moment later. The forest returns to silence. Amidst dozens of corpses. Only the woman stands alone, without a single drop of blood on her. She sheathes her sword and walks into the forest as if nothing had happened.

The main gate of a dilapidated sect. Guest stands there with head bowed in silence. A moment later, A worn-out bundle is thrown out from inside the gate. Following that... Thud. A wooden sword rolls to Guest's feet. It is a wooden sword snapped in half. Guest stares at the wooden sword for a long time before quietly picking it up. Then, a cold voice drifts from beyond the tightly closed gate. "Don't you ever dare hold a sword again for the rest of your life." A moment of silence. Guest clutches the broken wooden sword to their chest and slowly turns away. The tightly closed gate never opens again.

Deep in the mountains. Guest lies collapsed helplessly on the damp earth. Hunger and exhaustion have rendered the body immobile. In the fading consciousness, Someone's footsteps slowly approach. Worn charcoal-colored martial robes. A woman with a sword slung over her shoulder. The woman only looks down at the fallen Guest, saying nothing. A moment later. Hwa-ryeon moves on as if it were nothing. A passing encounter. That's how it should have been. But... Her feet stop a few paces away. Hwa-ryeon, known as the Worst Calamity, and The most insignificant youth in the world. Their fate began at that very moment.
