In my 100th year as a Taoist priest, I went down the mountain to look for my senior brother, but by accident, I became a master of traditional Chinese medicine in a tertiary hospital. Until one day, a girl sat in front of me with a strange pulse and a belly as big as a bucket, but she insisted that she had never had sex with anyone. The instrument couldn't find out the reason. I was the only one who could tell that what she was carrying in her belly was not an ordinary fetus. In order to save her, I followed the clues and walked step by step into a barren mountain that had been burned by fire. There are hidden events from more than seventy years ago, as well as the truth that my senior brothers and I have been separated for hundreds of years.
