Ning Wanyou is Liu Yichen's enemy, Chong Qianye is also Liu Yichen's enemy. If these two enemies were to tear each other apart, it would be a good thing for Liu Yichen.
But the key issue is that Liu Yichen doesn't want that grandson Chong Qianye to get with Ning Wanyou—an exceptional beauty he never had a chance with himself. Nor does he want Ning Wanyou, in a fit of rage after being with Chong Qianye, to kill him. If that happens, he wouldn't know what Ning Wanyou intended to do using Chong Qianye.
So, he can't let Chong Qianye make a move on Ning Wanyou. What should he do?
It's too late, the opportunity is fleeting. Ning Wanyou is already walking out of the bedroom in her nightgown. She wrinkles her nose and sniffs: "What's that smell? I feel like I've smelled it somewhere before."
Of course, Ning Wanyou has smelled it before. She saved Liu Mengxun, and the two even spent several days in bed together, so it would be odd if she hadn't.
"Liu Mengxun, Ehuang Mengluan!"
