A mountain village youth, Fang Zheng, was adopted and raised by his grandfather in an old courtyard among the mountains. After his grandfather passed away, he accidentally bound himself to a troublesome cultivation system—wanting to go down the mountain? First repair the courtyard, help the villagers, and accumulate enough goodwill values! From then on, he is forced into business, managing hot meals for working men, looking after children for mothers at their wits' end, and taking in stray animals as family. Every good deed completed miraculously renovates the dilapidated old courtyard a bit more, and the town at the foot of the mountain also grows lively. But when enough points are accumulated, he meets more and more ordinary people warming each other, and piece by piece pieces together the truth of his life experience. It turns out the most miraculous koi fish was never a divine miracle, but a heart willing to warm others.
