"I know."
When these three words came through the phone, Chi Jingxuan's heart experienced a moment of astonishment.
It was several months after Ruan Xu took over the treatment of Yu Wanqing that he diagnosed her infertility as a result of poisoning, and Gu Cheng'an said he knew.
"Anan, when did you find out?"
Chi Jingxuan asked in a deep voice.
A sigh was heard over the phone, and Gu Cheng'an said coldly, "After you guys appeared, Mom's frequency of episodes increased significantly. That's when I realized something was wrong. During the period Dad took Mom to M City, I hired a private detective to follow Gu Chenghui, and I also resorted to some unconventional methods. So, I found out that Mom was poisoned, not suffering from heart palpitations."
"And the fact that Mom was infertile, I actually knew a few years ago. But by the time I knew, it was too late to change anything, so I didn't tell anyone, fearing that it would sadden my parents if they found out."
