On the night of the Mid-Autumn Festival, a strange old man saved a dying little girl. The girl was too seriously injured and did not want to mention the past, so she lived with the strange old man. She thought she would live a normal life like this, but she didn't expect that those who killed her would come to massacre the village. The village was destroyed, but he was lucky enough to survive, and he was alone but didn't know where he was going. I heard that Yangcheng is the most prosperous area in Daguo, and maybe there will be a place of its own there. Alone, what will she encounter on the road, and what will she encounter in Yangcheng? Her life is a mystery and a destiny~
