Mohist Mechanism

Five years ago the fortune teller told me never to go home until I was 30. My grandfather's death five years later forced me to return to my hometown. Before the funeral had even begun, I knew a secret: my grandfather was the seventy-third descendant of Mozi, and I was designated the next. Grandpa left me a piece of the scroll, in order to understand the content of the scroll, I fell into one Mohist Merchanism after another. However, the secrets of Mohism and Mozi were gradually revealed.
