Song Shutian finished a glass of water. "Wait and see. We still need to investigate. But, my gut feeling is that this woman isn't an enemy agent. Otherwise, she would have made some moves over the years. You, focus on finding your mother's old friends these next few days to get some information from the side."

Ning Hao sighed and nodded. "You guys need to hurry up too. We have to find out the source of this stuff, otherwise, it'll be hard to say who will be poisoned next time."

Actually, Ning Hao wasn't that angry at this point. He still remembered what Jiang Qiao had advised him. In fact, compared to Jiang Qiao, he was much better off. At least his grandparents loved him, and he didn't have to shoulder the responsibility of a family at such a young age like Jiang Qiao.

But then I thought about it again, and realized that their lives were really not good. One of them was lost when he was young, and even if he were found, what difference would it make? She couldn't go to her parents' side, and there was also Grandpa Qiao.

As for her grandfather's side, his family background is quite oppressive. In fact, having parents is not much different from not having them. Jiang Qiao is still wandering around outside. Ning Hao knows Jiang Qiao's personality better than anyone else. She can do things herself and won't rely on others. She can rely on herself and won't rely on others.

In truth, he secretly wished that Jiang Qiao could rely on him, so that at least he could have a sense of belonging and mission, which would be better than being adrift and uncertain as he was now.

Compared to Ning Hao's feelings, Ning Boyuan's feelings were even worse. Being scolded by his own son like a grandson would make any father feel bad.

Knowing the cause of his ex-wife's death, how could he possibly have no thoughts about it during this time? It's impossible. The case has been filed, and even the police can't do anything about it; what can he do? So many years have passed, who knows how that woman was poisoned?

To be honest, Ning Hao is quite similar to his deceased mother in this respect—stubborn and inflexible. Before getting married, he actually admired Ning Hao's mother quite a bit; such an intelligent and beautiful woman would definitely make him look good in public.

Moreover, he knew more about many things than her, and since they had similar educational backgrounds, he felt they were a perfect match.

But after getting married, he realized that intelligence can't put food on the table. Knowing a lot doesn't necessarily mean knowing how to live, how to cook, or how to handle relationships with colleagues and neighbors.

What he used to think was intellectual was now seen as aloofness and being unsociable.

Ning Hao's mother's previous elegance and poise, in Ning Boyuan's eyes after marriage, lacked gentleness and romance. He needed a woman who could understand him, a woman who would revolve around him every day. This change in perspective naturally led to conflicts between the couple.

Actually, he himself couldn't explain what was going on between him and Tong Yun.

Well, he admitted that Tong Yun was very beautiful. Although she wasn't as good as his ex-wife in some ways, she was understanding, articulate, and well-liked by everyone around her. Of course, he admired people like that too.

However, he kept this affection to himself and never revealed it. He used to think that his wife was just making unfounded accusations, but he never expected that his son would say it all today.

He didn't think he had done anything wrong. He got drunk that time because some friends invited him to Tong Yun's place. He didn't expect to drink so much. He didn't know what happened afterward, but as a drunk person, he probably didn't do anything outrageous.

But he never expected that there would be such a twist in the middle. Back then, Tong Yun didn't say anything, and his ex-wife didn't explain it so clearly either. He thought it was just a misunderstanding.

It seems that Tong Yun is behind this, but he also secretly resents his deceased ex-wife. Why couldn't she have explained things more clearly?

If Ning Hao knew that his father thought this way about his mother, he would definitely scoff. His mother was such a sensible person, saving face for her father. This matter was cleared up, and even if there was a misunderstanding, it would only become a rift between the couple in the future.

Getting drunk is fine, just remember to go home. Everyone else has left, so why is his dad the only one left? No one with a brain would do that, unless the person who stayed is doing it willingly.

But Ning Boyuan didn't think so. He felt wronged. He didn't seem to have any real relationship with Tong Yun back then. At most, he had some feelings for her, but that didn't bother anyone. How could this unlucky son say such things to him, as if he had an affair with Tong Yun while still married?

However, when he thought of what his son had said, his face turned red with anger again. The reason why his ex-wife and son misunderstood each other was because of Tong Yun. What exactly did this woman say to Ning Hao's mother back then?

He slammed his fist on the table in anger, then stormed back.

Tong Yun was calling the children to eat when she said, "Oh, Lao Ning is back! Go wash your hands, let's eat. There's your favorite braised beef; I asked someone to buy it for you—"

She looked up and noticed that her husband's expression was a bit off. "What's wrong? Who upset you? Don't be angry. Getting angry while eating can make you sick."

Seeing Tong Yun like this, Ning Boyuan suppressed his anger again and again, but he couldn't hold it in any longer. He said to the children, "You eat first. I have something to say to your mother."

Tong Yun's arm hurt a little from Ning Boyuan's grab.

"What are you doing? Why are you using so much force? If you have something to say, just say it. We're all family, what can't we say to each other?"

Ning Boyuan dragged Tong Yun into their bedroom, his eyes red as he looked at her.

"To be honest, what did you and Ning Hao's mother talk about back then?"

Tong Yun was stunned, blinked her eyes, and looked aggrieved. "What can I say? This person has been dead for so many years. Are you crazy? Why are you bringing this up again?"

"What does this have to do with me? She's a dead person, why is she causing trouble for the living? Old Ning, have you taken the wrong medicine?"

Ning Boyuan looked the woman up and down again. He used to think she was wonderful. She didn't have to worry about anything at home, she got along well with the neighbors, and she handled things smoothly with her superiors and subordinates. He never thought about anything else and always felt that such a beautiful woman was being treated unfairly by him. But now it seems that's not the case.

"Didn't you say? You dare swear it?"

Tong Yun frowned slightly. "What do you mean? What kind of oath did I make? If you don't believe me, dig that woman out of her grave and let her confront me. I just don't believe that a woman who has been dead for so many years can still interfere in our lives. You're really confused."

Who exactly did you listen to? Honestly, you should just focus on living your own life; why are you listening to other people's nonsense?
