They say saving a dragon brings blessings, but after Guo Wancai rescued the Azure Dragon, he ended up losing his entire fortune. The Azure Dragon gave him an old scale in gratitude, which he sold for three hundred taels of silver, yet he thought it was too little. He even blocked the river to trap the dragon, forcibly gouged out her scales, and abandoned her on a muddy riverbank to die. A poor carpenter, Old Qin, and his daughter rescued the dragon overnight, asking for no gold or silver, only that she return safely to the river. Unexpectedly, several days later, torrential rain caused a disaster, leaving the entire village surrounded by floodwaters. Just as all hope of escape seemed lost, a dragon's roar suddenly echoed across the river, and the Azure Dragon returned, riding the wind and rain.
