An ancient, tattered book found buried in a decayed wooden box in the field. It documents rare melon varieties including the Rainbow-Striped Melon, Drunken Immortal Melon, and Sea-Sand Melon, along with detailed cultivation methods and grafting diagrams. It also contains cultivation notes on using plant ash for aphids, garlic water for disease prevention, and a drip irrigation system design. Possibly left by a melon fanatic from the previous dynasty.
