Ou Yunchen drove to the residential area where Xie Youlin lived. When Fan Zhijie told him that the elderly couple did not have fixed jobs, it made Ou Yunchen suspicious of Xie Youlin's care for them.
Following the clues provided by Fan Zhijie, Ou Yunchen quickly spotted the couple in the residential area.
But just as Ou Yunchen was about to walk over and have a chat, he ran into Xie Youlin, who was also coming downstairs.
Xie Youlin communicated with them using sign language.
Xie Youlin's sign language: "If you're not feeling well, don't come down to exercise. You should rest more in bed."
Liu Changhai's sign language: "I can't sit still, I still want to stroll around."
The old man chuckled foolishly, and they looked at Xie Youlin with kind smiles, as if they were looking at someone they knew very well. Their harmonious relationship was like that of a family of three.
Xie Youlin glanced at his phone, then ran off to the side to take a call.
Liu Changhai's sign language: "Old woman, go to the market and buy some pork ribs. We'll make pork rib soup for our son tonight."
The old woman next to him nodded and walked away.
But all of this was seen clearly by Ou Yunchen from a distance. The old man had gestured 'son,' and that son referred to... Xie Youlin!?
Coincidentally, Ou Yunchen also received a call.
— Ou Yunchen on the phone —
Pangzai: "Brother, I've arranged the time for you. My mom said this afternoon is fine."
Ou Yunchen: "Thank you, I'll be there this afternoon."
Pangzai: "No need to thank me. I even got to meet Xi Ya thanks to you and added her WeChat!"
— Ou Yunchen's call ended —
When Ou Yunchen turned back, both the deaf-mute couple and Xie Youlin were gone.
Ou Yunchen looked around but couldn't find them, so he had no choice but to leave the residential area and prepare to meet Song Yuandong.
***
Upon arriving at Song Yuandong's home, Ruan Miaomiao brought Ou Yunchen inside and then excitedly left.
Ou Yunchen had deliberately arranged for Xi Ya to ask him out so he could get Ruan Miaomiao away from Song Yuandong. He didn't want Ruan Miaomiao to overhear what he was about to discuss.
Song Yuandong: "Please sit."
Song Yuandong received Ou Yunchen in his study. The scent of tea filled the room, and the bookshelves were lined with various books.
Song Yuandong: "Didn't I say we shouldn't meet anymore?"
Ou Yunchen: "I think it's still necessary to talk."
Song Yuandong: "Talk about what? Tian Yu is already dead, and the Xie family only has one son left."
Ou Yunchen: "Sister Song, do you know Mrs. Xie?"
Whether it was a slip of the tongue from Song Yuandong or something she saw on the news, Ou Yunchen keenly sensed an unconcealable sadness when Song Yuandong mentioned Mrs. Xie.
Song Yuandong smiled wryly. It was clear she didn't want to answer.
Ou Yunchen: "But I heard that Mrs. Xie strongly dislikes you."
Song Yuandong's hand trembled as she poured tea, but she maintained a calm facade.
Ou Yunchen: "Sister Song must have seen the news. The young nanny who gave Mrs. Xie the wrong medication has been arrested and is awaiting trial."
Song Yuandong: "I saw it."
Ou Yunchen: "I heard it from her."
Song Yuandong: "How did you meet her?"
Ou Yunchen: "Because a few days before Mrs. Xie's incident, I met Mrs. Xie and saw the young nanny taking care of her alone at home. I happened to mention your name."
Song Yuandong: "What did Mrs. Xie say about me?"
Song Yuandong began to appear nervous.
Ou Yunchen: "When I arrived, Mrs. Xie happened to be having an episode. I saw how the young nanny cared for Mrs. Xie, and I believe she didn't intentionally try to kill Mrs. Xie."
Song Yuandong: "Yes..."
Ou Yunchen: "However, it was only when the young nanny mentioned your name that Mrs. Xie became agitated again, cursing you incessantly and saying that you were the one who killed her son."
Song Yuandong: "I... I didn't!!!"
Ou Yunchen: "Actually, you already knew that the current Xie Youlin is not Mrs. Xie's biological son, because you killed her biological son by dropping him, didn't you?"
Song Yuandong: "Don't talk nonsense!!!"
Ou Yunchen: "Whether I'm talking nonsense can be settled by taking a paternity test with Xie Youlin."
Song Yuandong: "Xie Hongtian and Tian Yu have been burned to ashes, how can we do a paternity test? Stop trying to scare me!"
Ou Yunchen: "I didn't say a paternity test with whom. What if it's Xie Youlin's biological parents?"
Song Yuandong's legs buckled, but luckily she held onto the table.
Ou Yunchen: "Don't worry, Sister Song. No one knows what I've told you yet."
"But to get the young nanny a lighter sentence, she mentioned your name before the incident. It's uncertain if people will investigate your relationship with Mrs. Xie."
Song Yuandong: "No..."
Ou Yunchen: "That depends on whether Sister Song is willing to help me."
Song Yuandong stood by the window, taking a long time to compose herself. She had never spoken of that past event to anyone.
