Tang Ze on the side looked at Conan and found that the other person's eyes were full of solemnity.
Tang Ze knew that Conan must have mistaken the intelligence and temporarily thought that Rena Mizunashi was a member of the Black Organization who had killed Eisuke's sister and disguised her identity.
Because if Rena Mizunoshi is type O, but lies that she is type AB because she needs to hide her identity, then she cannot receive a blood transfusion.
Because type O blood can only accept type O blood, since Rena Mizunoshi later received a blood transfusion because she fainted, it proves that the other party did have type AB blood.
In addition, although O-type blood is a universal blood transfusion type, it can only be donated in small quantities to people with other blood types.
Since she donated so much blood that she fainted, it must have been a large amount of blood. So, theoretically speaking, the conditions for lying about blood type may be met, but it is impossible to do so in practice.
"Failed..." After understanding these screening conditions, Sonoko said with some disappointment: "Your sister is really not Rena Mizunashi..."
"I've been saying that since the beginning."
Hondou Eisuke gave a helpless smile, and looking at the lost Sonoko, he began to comfort her: "It's okay, at least we have ruled out a wrong direction of investigation today."
"By the way, since we're talking about investigation, why not let your brother-in-law help you investigate as well!"
Hearing this, Yuanzi suddenly remembered something and quickly suggested, "Brother-in-law is a criminal. It's definitely better for him to find someone than to do it alone."
"Isn't this too troublesome? Detective Karasawa has a lot of things to do, right?" Hondou Eisuke said hesitantly.
"That's no problem. I'll keep an eye out for you." Tang Ze had originally planned to participate deeply in Hondou Eisuke's journey to find his relatives. He was thinking about how to start the conversation, but he didn't expect his sister-in-law to assist him.
"Really?" Hondou Eisuke was delighted when he heard that. "Thank you so much, Detective Karasawa."
"It's okay, but I'm still a little concerned about your blood type. I wonder if you have donated blood or been seriously injured recently?" Tang Ze asked.
"I don't have any of that. I was seriously injured in a car accident when I was a child, and that was when my sister gave me a blood transfusion."
After Hondou Eisuke finished explaining, he said, "But if Detective Karasawa is so concerned, I should be able to confirm it when I go to the Okudaira family in Haido-cho 3-chome tomorrow to pick up some things.
My mother and I used to stay with a family that took good care of us. They contacted me to go there and bring back my mother's belongings."
"You said relics..." Xiaolan hesitated and said, "Is my mother already dead?"
"Well, it's because of my illness," Hondou Eisuke explained. "I heard that among those relics is the parenting handbook that my mother used when she gave birth to me."
As for why people don’t go to the hospital, this is also due to different national conditions.
In Neon, the procedure for going to the hospital is very complicated. Not only do you need to make an appointment, but you may also have to wait in line for a long time.
In contrast, going to an acquaintance to pick up the belongings left by the mother and getting blood type evidence from the parent-child handbook is actually killing two birds with one stone.
But, he really missed out on important clues because of this.
If he went to the hospital for a blood test, he would be able to confirm that Rena Mizunashi was his sister.
I can only say that I am a non-African, and my luck is really a little bit bad..
"Why don't I go with you? If that family has seen your sister, we can ask them about it." Tang Ze smiled and offered to join.
"Is this... too much trouble?" Hondou Eisuke said embarrassedly.
"It's okay. It's Saturday and Sunday anyway, so I have nothing to do." Tang Ze smiled and said, "Also, I seem to have some impression of the Okudaira family in Haido-cho 3-chome you mentioned. It's half public and half private, right?"
"Official business?" Xiaolan asked in surprise, "Is there a case?"
"Well, a year ago, a murder occurred in the Okudaira family in Haido-cho 3-chome. The deceased was his son."
Tang Ze nodded and said, "I've seen it in the files before, and since Hondou-kun mentioned it, it's a good opportunity for us to go and take a look together."
"If that's the case, let's go visit together tomorrow." Hondou Eisuke smiled and said, "With Detective Karasawa, the case will definitely be easily solved."
"I have something to do tomorrow, so I'll pass." Sonoko waved her hand and refused to join the main story again.
I have to say that although Sonoko is the "case trigger princess", she doesn't participate much in the main line. Every time a main line happens, she basically has something to do and doesn't join in.
In a way, she is extremely lucky.
After everyone agreed to investigate again tomorrow, they said goodbye to Anno and left.
Because it was time for dinner, Yuanzi enthusiastically suggested going to eat.
However, Tang Ze and Conan had something to discuss, so they started to make excuses.
"Okay then, brother-in-law, you go home and have dinner with your sister, and little brat, go home and do your homework. The two of us will go out to eat."
Yuanzi chuckled and walked towards the back seat of Tang Ze's car: "But I still need you to take us to the Rice Flower Commercial Street."
"No problem." Tang Ze first sent Sonoko and the other person to their destination, and then turned back to send Conan home.
Of course, going home is not the point; the key lies in the conversation along the way.
Neither of them spoke first. Instead, Conan called Teacher Judy first, told her what happened today, and asked her to help investigate the "pany" matter.
After that, he also told Judy about Hondou Eisuke looking for his sister, and confirmed from her that Mizunashi Rena's blood type was indeed AB.
