A broken blade and half of the broken music led to a hundred years of evil calamity. Duan Wufeng, a young man, carries the inheritance of Dagger Ming and the blood feud of annihilating his family. He struggles to rise from the bottom of the world, and searches for the truth amidst the pursuit and conspiracy. He thought he was just avenging his father and avenging his teacher, but he didn't know that he had already been involved in a shocking situation that spanned the rise and fall of dynasties and entangled the fate of good and evil. The ancient demon god "Ancestor Netherworld" will break out of the seal, want to sacrifice blood to the people, and return to the world. The origin of the Five Elements is scattered around the world, and it is the only hope to seal the demon. From the water of Xuanyin in the cold abyss of the North Ming Dynasty, to the purifying fire of Guixu in the South China Sea, from the sharp energy of Gengjin in the West Kunlun Sword Tomb, to the Sky-Mending Relics of the Hidden Sword Villa... Duan Wufeng travels all over Jueye, experiencing life and death. Accompanied by his best friends and beauties, and in the rites of betrayal and sacrifice, he gradually uncovers the shocking secret of his own bloodline and gathers the power of the five elements. However, the biggest crisis does not come from the outside world, but the will of the ancient "Sword Demon" lurking deep in his soul. When the five elements gather together and the Tao Seed of Chaos is first formed, the lurking spoon demonic thoughts suddenly awaken, attacking internally and externally, and seizing the body is imminent. In the thin line between life and death, the brand of guardianship left by Master Beiming appeared, and he passed down the supreme method that transcended the five elements and pointed directly at the origin of Huantun - "The Return of Chaos Jing". Is it to become the perfect container for the rebirth of the devil, or to refine the devil's thoughts, use the way of returning chaos to its origin, control the five elements, and end this catastrophe sweeping the world? The undercurrent of the dynasty, the dispute between the workers and the lake, the duel between good and evil, the dilemma of love and loyalty, everything will usher in the fateful ending in the final battle to seal the demon. The article is an epic about growth, sacrifice, choice and protection.
