Su Xiaofu stood amidst the crowd; currently, everyone was watching the quarrel at Su Yunjin's residence and nobody noticed her foot movements.
Su Xiaofu, to act without leaving any traces, specifically chose a spot in the crowd where she would be least noticeable, so when Su Yunjin approached, she could kick the stone and no one would suspect her. Focusing on the visibly pregnant Su Yunjin's belly, Su Xiaofu was sure that kicking the stone would most likely trip her.
If Su Yunjin fell, it would be difficult to save the child inside her. The people from the village and the town were all talking about how lucky Su Yunjin was, having her unborn child predestined as the daughter-in-law of Prince Rui. Ha! Now, by kicking a stone, Su Xiaofu could make Su Yunjin miscarry and see how her child could still become the daughter-in-law of Prince Rui.
