Chu Qianli naturally knew who "he" referred to in Chu Lingyang's words.
She just hadn't expected Chu Lingyang to become so agitated.
What she expected even less was that even Chu Lingyang was unaware that Uncle Nine was still alive.
When the Ninth Prince "died," he truly "died." Apart from Feng Wuya and Feng Yexuan, those younger generations, he had actually not told even his closest and best friends.
It was indeed a "death" that seemed very real.
However, Chu Qianli ultimately didn't know the relationship between Chu Lingyang and Feng Dingchu; hence, she did not directly respond to Chu Lingyang's question.
"Prince Ling, please let go of me first before we speak," she said in a deep voice, her attitude not quite cold.
But neither was it particularly warm.
Only then did Chu Lingyang realize his action had been inappropriate.
