Song Chengyi didn't answer, and asked, "Why didn't we come out together yesterday?" ”

"Don't mention it, I was just about to set off, and another patient came, so I was urgently recruited back, I feel that doing our job is busier than you soldiers!" After speaking, he raised his hand and looked at his watch: "It's almost noon, do you want to eat in the cafeteria with me?" ”

"Yes, you go to dinner and come back, I'll wait for you here!"

Cheng Chuhao was choked, and after two seconds: "Okay, you are the uncle, I will run errands, wait, the little one will go to feed you!" ”

Soon, Cheng Chuhao came back with a few aluminum lunch boxes, two servings of white rice, one soup, one vegetarian dish, and two small fried meat: "It's hearty enough, right?" Don't say that every time you come to me, there is nothing good to eat, I don't treat you badly! ”

Song Chengyi didn't answer, picked up a portion of rice and began to eat.

Cheng Chuhao stuffed a large piece of meat into his mouth and asked, "What is the matter with you that you came to me, right?" ”

"Well, last time I heard you say that you can use medical methods to determine whether two people are related by blood?"

When Cheng Chuhao heard this, he instantly came to his senses: "Well, there is such a statement, why?" Who and who are you going to identify? Let me guess, is it to identify you and your sister? ”

Song Chengyi glanced up at him, with a gossip on his face, and then lowered his head and continued to eat: "How did you think of me and her?" ”

"Isn't it easy? Your sister is the most individual, the most special. Let's talk about looks first, big brother, you, Xiaozhi, the three of them all have something in common, either like a godfather, or like a godmother, only Linzi, no one is like it, and they are in a class of their own. Secondly, talking about character, if there are good or bad children in a family, in addition to cultural differences, there is only one possibility, parents are partial, doting, and spoiled, but in your family, there is no such situation, right? Whether it is a son or a daughter, the godfather and godmother are treated equally, the same education, the same growth environment, and can develop different qualities, which can only be said to be due to nature. Do you want to identify you and Linzi? ”

"Good analysis, but you're thinking too much!" Song Chengyi never thought that Song Chenglin might not be his own sister.

"This is thinking too much, I have been studying psychology and behavior recently, and your family's situation is a typical example!"

"Okay, don't study our family, answer me first, how to identify whether two people are related by blood?"

Song Chengyi handed over the matter to the Gu family for investigation, but it didn't mean that he could be 100% relieved, even if the Gu family said in the end that Ning Ning was really their family's youngest daughter, Song Chengyi would only believe it if he confirmed it through other methods.

"Now the medical level of our country is limited, and we can't do it, but we can!"

Song Chengyi glanced at him unhappily, doesn't this mean that he didn't say anything? With his current status, it is basically impossible to go abroad at will, and it takes a long time to write an application and review it.

However, the more mysterious he looked, the more curious Cheng Chuhao became: "Or, tell me who and whose appraisal you want to do?" I'll help you figure it out. ”

"What can you do?"

"Don't underestimate me, after the New Year, I will go to the United States for a month of study, and when the time comes, I will help you collect blood samples or hair samples and bring them to a medical institution for identification." 2k reading web
