"Shut up and leave now, or I'll be angry with you."

놛 wants to find out whose father Zhou Yaozu is, but that doesn't mean 놛 is willing to listen to Sun Lan's disgusting words.

Sun Lan thought that the apology was so disgusting to Xie Linan that he couldn't eat.

Seeing that she was about to fall out with anger, Sun Lan dared not say anything and retreated with a nod and a bow.

The world is finally quiet.

They went back to work and didn't talk about it anymore.

At night, after the children had fallen asleep, Xie Linan and Ye Xiaozhen went to the first floor to find Xie Linli and Xie Linqi. They sat together and began to analyze what they had seen during the day.

"From her reaction during the day, it seemed like she didn't know whose child it was. In her opinion, it should be Old Man Zhou's."

"That's true. When you asked her, she didn't look hesitant. But sister-in-law, didn't you say that so many relative matching tests failed? Doesn't that mean the probability that the boy is related to our family is high?"

Xie Linqi also said: "Yes, sister-in-law, and she said that the boy was born prematurely. Do you think it is possible that he is not born prematurely, but born at full term?"

Ye Xiaozhen nodded, "Yes, that's possible."

Xie Linan said, "If it was a full-term birth, how could she not know that she was pregnant? Look at her expression, she has never thought about the father of the child. If the child is really the father's, she told us directly, how could we not agree to save it?"

"Yes, it's really strange. Is that boy your biological brother?"

"It would be great if the paternity test can be done, but what if it can't be done? Should we still save the child?"

Ye Xiaozhen said, "Second brother, it's too early for you to worry about these things now. Let's test Zhou Yaozu's date first and see if it's right."

"If it was premature, it would probably match."

"If they match, then you can go to the hospital with us to do a blood typing test, mainly to check your blood type."

"Can you check your blood type?"

"Not accurate, but if the blood types don't match at all, then they definitely don't have the same father. If the blood types match, then we can take the next step."

Xie Linli scratched his head and said, "It's so complicated, sister-in-law. You haven't read much, how can you know so much?"

Ye Xiaozhen was also quite surprised. How come high schools and middle schools nowadays don’t even teach these things?

You went to chemistry class, right?

"놖늀 likes watching TV and reading newspapers. I saw it on TV and in newspapers."

"oh."

"Hey, doesn't she even know whether she's pregnant or not?"

"It's hard to say. Normal people judge whether a woman is pregnant or not by whether she has regular menstruation. But there are rare cases where a woman has her period even though she is pregnant. This is especially common in older women."

When discussing women's matters, the two brothers-in-law felt a little shy and turned their heads away unnaturally.

Xie Linan took a deep breath and said, "Don't make wild guesses. Let's talk about it after we meet the person tomorrow."

"Okay."

They opened the door, but found that the old man had been standing at the door eavesdropping at some point.

Xie Linan was startled when he saw it when he opened the door.

"Grandpa, what are you doing in the middle of the night?"

Lin Xinghua: "I want to see what you guys are doing in the middle of the night."

"Nothing to do, just chatting."

"Don't try to fool me. I heard everything."

Xie Linan: “…”

"Humph, you old man, you are so ignorant, how can you lie on the door and eavesdrop on people's conversations?"

"If you don't want to eavesdrop, can you tell me? Lin An, what do you mean? Um, your mother got another little brother?"

You even know all this?

I don't know how much I have eavesdropped on.

Seeing that he could no longer conceal the truth, Xie Linan confessed the matter.

"Alas! It's not that we are hiding it from you on purpose, but we are not sure whether the child is our younger brother."

"What do you mean?"

"It's not certain whether this is Daddy's child, we still have to verify it."

놛 explained the whole process to Lin Xinghua.

The old man was a little excited when he heard this, "So, you are not the fourth siblings, but the fifth? Your father has five children."

Xie Linan held his forehead and said, "Didn't I say it? I'm still not sure."

"Why are you unsure? Didn't Xiaozhen say that you didn't match your four sisters and a bunch of cousins ​​there, so there's a high probability that you have no blood relationship with them. If you have no blood relationship with the people there, then it can't be your father's child, right? And you just said that you were born prematurely, so it must be your father's child."

"This... you can't reason like that. This kind of thing needs to be verified."

"Then you go and identify it."

"Why are you in such a hurry? The appraisal fee is not cheap. Take a look first. Only make sure you are not sure before you appraise it."

"You don't need the money."

Xie Linan looked helpless, "Grandpa, this technology is not open to ordinary people. It can only be activated in criminal cases. If we ordinary people want to identify it, we have to find some connections."

"I know you have a lot of connections."

Xie Linan: “…”

Ye Xiaozhen suddenly remembered something and said, "Hey, I do know a simpler way to determine whether a brother has the same father."

"What method?"

"Let Grandpa identify her and determine her relationship with Grandpa."

Um?

"If you are sure that the child is from the same mother, then it is definitely difficult to distinguish whether it is from the same father with the current technology. However, if the child is not the father's, then it has nothing to do with the grandfather, so it must be easier to identify the grandfather."

Lin Xinghua said: "Okay, let's do the appraisal."

Xie Linan: "Let's talk about it when we meet tomorrow. Grandpa, please control yourself. We are not sure about this matter."

"Okay, got it."

…

Early the next morning, Sun Lan came with her little son.

Zhou Yaozu was still thin and dark, and his face was not dark like normal, but dark blue due to liver disease, which looked quite scary.

But she has good facial features and a tall figure. It seems that if she is not sick, she should be good-looking.

This person definitely doesn't look like someone from Dongcheng at all.

"You are not feeling well. Please sit down."

Xie Linan was quite caring towards me.

No matter if he is our biological brother or not, he is a patient.

Zhou Yaozu nodded slightly, thanked him in a low voice, and then sat down aside.

Lin Xinghua felt very distressed when he saw it.

An eight-year-old boy is suffering from illness. Even though he is not my grandson, I feel sorry for him.

"Child, it's so early, have you had breakfast?"

Zhou Yaozu shook his head and said sheepishly: "We came here together, but we haven't eaten yet."

"Then Grandpa will get you some food. What do you like to eat?"

Xie Linan: “…”

놛 stared at the old man with a dark face.
