In Cangxuan Continent, vitality is like a tide, demons are dormant, human monks use martial arts to prove the Tao, and use Dharma to understand the mysteries.
Yang Shuo, a young man, was born with the "Xuansha Demonic Vein" and his left arm was born with ominous black energy. He was regarded as a disaster star and received cold looks. When he was sixteen years old, the demonic bloodline went berserk. In order to save his loved ones, he cut off his left arm. However, he accidentally aroused the forbidden power deep in the bloodline, attracting a mysterious and ancient alien species carrying ancient runes - the golden-eyed Black Feather Eagle (referred to as Moyu).
He tried to survive with a broken arm, but the divine eagle recognized him as his master. Mo Yu is not only psychic, but also contains fragments of the ancient demon saint's inheritance. Under the guidance of Mo Yu, Yang Shuo embarked on an unprecedented path of "Double Cultivation of Mysterious Demons": using the orthodox mysterious skills of the human race to refine the vitality of heaven and earth and nourishing his own body; using his demonic veins to swallow evil spirits and temper the indestructible demonic body. One good and one evil, twins in one body, testing wildly on the edge of destruction and rebirth.
The road ahead is full of thorns: the giant demon king who covets Mo Yu, the human holy land who regards the demon vein as a heresy, the mastermind behind planting the demon vein, and the childhood sweetheart Leng Yuening who feels guilty and has a love-hate relationship because of his broken arm... And the Ten Thousand Demons Palace that is ready to subvert the world.
Yang Shuo's left hand is empty, with black feathers as wings. Xuan Gong Demonic Body, defying heaven and changing your destiny! With his incomplete body, he controls the power of the mysterious demon, forges magical weapons, practices extraordinary skills, and controls the divine eagle. In this strange and chaotic world of mysterious demons, he slays demons and demons, protects what is precious in his heart, and composes a most powerful mysterious demon battle hymn belonging to the Broken Arm Condor Hero!
Ask the vast continent, who is in charge of the ups and downs? I am the only master of the mysterious demon, Diao Xiao Jiutian!
