Lu Ming, a mortal boy, was born in the Age of Dharma, when immortals and mortals are separated forever. Because of a mysterious jade pendant, he was able to glimpse the door to cultivating immortality, but he also became involved in the dispute between good and evil and ancient mysteries. The road to immortality is rugged and people's hearts are unpredictable. Faced with the superior Immortal Sect, the Demon Sect plotting to resurrect, and the mastermind who regards all living beings as pawns, Lu Ming uses his mortal body to ask questions.
He does not practice the ruthless way, and does not admire the Immortal Immortal. He only wants to protect the way in his heart in the world of mortals. From a border town to the top of the Nine Heavens, this is a heaven-defying road belonging to mortals, a mortal song that resounds throughout the world.
