Jing Li travels back to ancient times and becomes a rare little koi fish, possessing a koi buff that can quickly bring good luck to those around him. The little koi fish ends up in a remote mountain village, where he is picked up by the village's infamous sickly man. The sickly man, named Qin Zhao, arrived in the village three years ago with no memory and a mysterious identity. He was so ill that he could hardly move and was ostracized by the villagers. Seeing Qin Zhao's empty earthen house, Jing Li decides to help him. The little koi fish wags his tail at Qin Zhao: I heard I can help fulfill wishes! Qin Zhao: Anything? Little koi fish: Yes, yes, yes! Qin Zhao smiles faintly: I want a husband. From a certain day onwards, the sickly man in the village suddenly recovers and starts having a streak of good luck. He digs up rare herbs in the mountains, saves the son of a wealthy merchant, and even turns up a silver ingot while plowing the fields. He builds a house, gets married, and establishes a private school. The villagers are so curious they try to steal his secret to good fortune. They see the sickly man squatting by the pond, gently coaxing the bright red koi fish that is bubbling at the bottom: "Come out and eat, I won't make you have little fish anymore."
