Episode 3 recap: Mo Bing killed Ru Fei's bugs.

Ru Fei told her little ones to go out and get fully poisoned for themselves. Mo Bing saw many bugs outside the house and ordered the servants to quickly spread poison and kill all the bugs. Ru Fei felt the connection between the poisonous insects in the mansion and herself was severed, and she spat out a mouthful of blood. Mu Yuan Qi saw this and quickly came to ask Ru Fei what happened. Ru Fei told him that Mo Bing killed the poisonous insects in the mansion.

Mu Yuan Qi deeply regretted marrying Mo Bing. He felt that the woman was constantly opposing him. Ru Fei told him that marrying Mo Bing actually had its benefits for him because Mo Bing was from the General's Mansion, and her influence in the court would undoubtedly be of great help to him. She advised Mu Yuan Qi not to act rashly against Mo Bing.

Ru Fei told Mu Yuan Qi that the Lingxi poison in her body had no solution and could only be countered with the poison inside her. Ru Fei never expected to be harmed by the Lingxi poison. She told Mu Yuan Qi that she needed to rest and cultivate for a period of time. She instructed Mu Yuan Qi not to let Mo Bing leave the Wang Mansion until she came out of seclusion. Mu Yuan Qi returned to the room and stopped Mo Bing, who was killing bugs.

Mu Yuan Qi asked Mo Bing what she was up to. Mo Bing said she was doing it for his safety. Mo Bing planned to find a way to erase Yu Sanniang and Xianyun's impressions from Mu Yuan Qi's mind because she didn't want to be manipulated anymore. Mo Bing pretended that Yu Sanniang wanted to commit suicide by hanging and confined Xianyun.
