Little Dragon Girl is several years older than Yang Guo, but she has lived in an ancient tomb since she was a child, studying internal skills with her master and never considering her own desires. And Yang Guo is mixed with sorrow and joy, so when they get married, it's like last romance. The ancient tomb school has the positive and negative hints of "Twelve Less, Twelve More": "Think less, think less, desire less, do less, talk less, laugh less, worry less, be happy less, be happy less, be angry less, be good less, and be evil less. Doing this 12 times or more is the cost of health care. Too much thinking leads to no spirit, too much mental loss, too much tiredness, too much shortness of breath, too much laughter hurts the liver, too much worry, too much fear, too much joy, too much anger, too much forgetfulness, and too much anger. How good it is, you cling to it, and how evil it is, you will have no peace. This twelve plus is the foundation of death. " The little dragon girl was raised from an early age, carefree and carefree. The purity of her skill is inferior to that of her grandmaster Lin Chaoying. But then Yang Guo came to the grave, and they got along for a long time, and their feelings faded. This rule of "less talking, less doing, less happiness, less sadness" has gradually failed to persist. Separated after marriage 16 years, Yang Guo wandered in the dust, wandering in the rivers and lakes, worried, with stars on his temples; The little dragon girl lives in a deep valley, although she can't help but miss it. But 20 years later, her skills are serious. After a few years, she practiced the trick of "twelve little", thinking less, wanting nothing, living alone at the bottom of the valley, but she didn't feel lonely. So, when they meet after such a long separation, it seems that Yang Guo is older than her.
