On the plains, the thousand-year kingdom fell apart. The sacred tree that once protected all living beings withered, the ancient seal loosened, and the shadow spread from the abyss, swallowing up the city-state and the wilderness. In this declining land, Karen, the last descendant of Jifeng Castle, has been burdened with the humiliation of her family's decline and the unknown secret of her bloodline since she was a child. When the Night Hunter breaks through the ruins of the castle, the rusty ancient sword awakens in his hand, and the flowing blood actually resonates with the lost ancient runes.
In order to find a way to seal the shadow, he embarked on a journey across the plains. On the way, he met the silver-haired ranger who bore a blood feud, the Templar knight who upheld his faith, and also encountered the ambitious separatist lord and the monster corrupted by the shadow. Every step is stepped on thorns and fire, and every confrontation is a matter of life, death and glory.
Classical oaths echoed in the wind, and majestic war songs ran throughout the journey. Using blood as a torch and loyalty as a blade, Karen searches for the light of dawn in despair. Not only does he have to fight against the external dark forces, but he also has to break free from the shackles of his family's destiny. In the disintegrated kingdom, he must gather the scattered forces of justice to protect the last hope of Cangyuan, and launch an expedition across the mountains and seas toward the throne that symbolizes order and hope.
