The Black Stone Valley: A Grave Mystery

On the seventh day after his father's death, three grave-robbing sects confront the family at the tomb. A final letter reveals the thousand-year secret of Black Stone Valley—if the petrified monk awakens, the Hehuang region will become a dead zone. Man-eating flowers, guardian white monkeys, Kucha's revenge murals... He is drawn into a millennia-long scam for immortality. At the end of the truth, deep in the snowy mountains, a golden arrow inscribed with Tokharian script awaits him.
