When I woke up, "I" with amnesia found myself in Yunjin Temple, and from then on my life depended on this Taoist temple in the mountains. Everything here seems to be favored by time, the fruit trees are evergreen, the flowers and plants are unbeatable, and even the chickens have broken through the boundaries of life. My appearance has not changed in three hundred years, and "I" have also changed from a down-and-out traveler to the "Yunjin Immortal" respected by the villagers. Until that day, a wooden bathtub floated from the stream down the mountain, with a swaddling baby inside and a wooden sign with the word "cold" engraved on it, breaking the long-term tranquility. Is it the call of fate or the beginning of an unsolved mystery? When an immortal man meets an unknown child, what kind of waves will Yunjin Temple cause?
