Both individuals were caught, and the matter was ultimately investigated thoroughly. There wasn't really any grand conspiracy; it was simply the handiwork of Cheng Miaoran and Shu Jingyun.
The sequence of events was that Shu Jingyun had inadvertently learned from Cheng Miaoran that Fu Yurou was pregnant. Since Fu Yurou was recuperating in Beijing, even though she had the help of the "young lady doctor" from the System Mall to monitor her own health, Chang Meihua was unaware of the specifics. Thus, she had to go to the Military Region Hospital regularly for check-ups with Old Liu. Cheng Miaoran, who frequently went to the Military Region Hospital to curry favor with Old Liu, discovered this.
As it turned out, even after leaving the Military Dependents Quarters, the former mistress-servant duo of Cheng Miaoran and Shu Jingyun had maintained contact. Their connection stemmed from Shu Jingyun’s dissatisfaction with her own life; she always needed someone to bully, and to divert her attention, Cheng Miaoran had told her about Fu Yurou. Shu Jingyun, harboring deep resentment toward Fu Yurou and blaming her for her current circumstances, conceived a malicious and sinister plan. She pressured Cheng Miaoran to find a way into the Military Region Hospital to harm Fu Yurou’s newborn child, intending to cause Fu Yurou agony.
