The Mystery of Jade Pendant

Chen Cheng, a 19-year-old mountain boy, has lived in seclusion in the mountains with his grandfather since he was a child, collecting herbs for a living. On December 31, 2025, before his death, my grandfather left a shocking secret: they were originally a famous traditional Chinese medicine family in old Shanghai - Chen's Medical Pulse, but they suffered a tragedy within a month of eighteen years ago - my grandmother died suddenly in the night, my parents died in a car accident, and all the cats, dogs, chickens and birds raised in the home died overnight, and no one survived. However, he and his grandfather were stranded in the mountains while gathering medicine and managed to escape the disaster. Before his death, his grandfather gave him a mysterious jade pendant and whispered: "The truth is hidden in jade."
