The Strongest Village Guard

There is a saying in an ancient book: A foolish and wise person, in order to maintain the peace of the land and water, lost one soul and two souls and was reincarnated as a fool. This is the village guard, also known as the soul-soothing person! Three souls go to one, seven souls go to two, no one asks what you eat during the day, and you kill demons with your sword at night!
