Yan Fei looked over and indeed saw a broken tree branch lying on the ground. This branch was just broken off from the tree, and because it was rich in plant fibers and still had a lot of moisture, it was very tough. Even a strong man might not be able to break it easily. But Lu Pingping broke it easily, which is why she was puzzled and asked Yan Fei if she was getting muscular.
Looking at Lu Pingping's current state, Yan Fei seemed to see his past self. When he first got the drone, he also experienced an unexpected increase in strength and couldn't control the sudden surge of power in his body. But he was transformed by the mysterious energy of the drone, so why did Lu Pingping also experience such a situation? Could it be that she had some kind of adventure?
