Zi Li has lived for more than a thousand years and has seen too much life, old age, sickness and death, joys and sorrows in the world. He used to like wandering around the world. At that time, he liked the excitement of the world, the different emotions of each person, and their vitality and creativity to make his life more colorful. However, people will grow old and die. After he watched the people he loved die countless times, he no longer wandered around the world all day long, but returned to the mountains and forests. He had gone from being extremely sad and happy to being calm now. Zili thought that he would no longer have any strong feelings. After all, a thousand years can allow too many things to be forgotten, including feelings.
