How Many Lifetimes Does It Take for a Stone to Be Smashed to Become a God?

I am a stone. When someone picked it up, it turned into a stone axe; after being chopped, it turned into bronze. In my lifetime, I have accompanied young generals who opened the border, white-haired veterans guarding the border, and a teacher who refused to fall under the city wall of Nanjing while holding a broken knife in his hand. Every life ends in fragmentation. Every life I thought it was the end. Until my last life, I became a humanoid combat robot. When facing the alien mothership, I suddenly remembered - a hundred lives ago, I promised a person that I would keep the dawn for him. This life will not be broken.
