Zi Yao nodded, "Uncle must keep it secret, and only those who can find a private detective must be trustworthy, since she has been able to hide for many years and let everyone be led by the nose, it shows that she or the person who helped her has a certain ability, and we have to prevent them from destroying the evidence!"

Bai Qifeng was also relieved to see that Yanyan was so thoughtful, "Don't worry Yanyan, now that your uncle is in charge for you, we are not afraid of anything, no matter if she is a poisonous snake or a beast or a cow ghost and snake god, she can't make waves in front of us!"

If my uncle's connections in Kyoto are not used, if I really need to use them, I can stab Huaguo into the sky!"

Zi Yao believed Bai Qifeng's words, his sister's death was the place where he blamed himself for many years, and he felt that he was too busy with work at that time and neglected his care for his sister, and when he found out, he was powerless to return to heaven, so he would say so when Zi Yao proposed all this.

Zi Yao stood up and bowed to her eldest uncle, "Thank you, uncle!"

Bai Qifeng hurriedly helped Zi Yao up, and said with a straight face: "What is this for, I'm going to be angry with my uncle so politely, you just live here! Don't go back to Su's house, I will find a chance to tell Su Wenchang later!"

Zi Yao shook his uncle's arm, "Uncle, don't be angry!" My father is very supportive of me going back to the Bai family to see, he has been busy with engineering in QD City for the past year or two, and rarely goes home, so I didn't talk to him, and you don't blame him, how can he think about these things just when he is sad." ”

Bai Qifeng sighed, "Alas, don't say that your father is really good to the little sister, if the little sister doesn't get sick, they will be a very compatible couple, but the most bitter is you!"

Zi Yao smiled, hugged Bai Qifeng's arm and said, "No, I'm fine now, there are so many people who love me!"

In an instant, Bai Qifeng was amused by Zi Yao, and yelled at his son, "Stinky boy, you have to take good care of Yanyan at school in the future, if someone bullies her, be careful that I will beat you!"

Bai Xunan had a bitter face, "I know, it turns out that I am the exploited and oppressed people living at the bottom of society!" The three of them laughed together.

The next morning, the uncle left, Bai Xunan also asked Ziyao to get up early, and the two rushed to the medical school of East China University, because Bai Xunan had already contacted the tutor, hoping to borrow DNA testing equipment to use it, and the tutor was very surprised to agree, so that they felt medical school before nine o'clock.

The two appeared in her office on time, she pushed the heavy glasses lenses, and asked Bai Xunan seriously, "The equipment can be borrowed from you, but will you use it?"

Bai Xunan was a little embarrassed, and tugged on the sleeve of the tutor, "Professor Sun, save me some face!"

Professor Sun spread his hands and shrugged his shoulders and said, "It's not a matter of face!"

Zi Yao couldn't help but smile, knowing that people who do academics are more rigorous, and what they worry about must be confirmed, "Hello Professor Sun, I will use the equipment! If you are worried, you can watch from the sidelines!"

Professor Sun leaned closer to look at Zi Yao, pointed at her and asked Bai Xunan, "Your girlfriend is so beautiful!"

Bai Xunan endured it, raised her eyebrows and explained calmly: "Her name is Su Jiayan is my cousin, and Yanyan is Professor Sun, my mentor!"

Professor Sun nodded, turned around and led the two to a laboratory at the end of the second floor, opened the door and invited them in, then changed his shoes and walked inside, explaining: "It's not that I don't trust you, this device is a German operation interface, and I don't understand it very well, so I can't help you!"

Zi Yao smiled, "It doesn't matter, my German is still fine!"

Professor Sun paused, turned back in surprise and asked, "Really, then can I record your operation in a while and record it for you on the side?" I want to learn the operation of this machine!"

Zi Yao nodded gently, having experienced so many worlds, this Professor Sun's appearance reminded Zi Yao of her original self, so she simply agreed, and now Professor Sun was happy, and pulled Zi Yao into it quickly, and introduced it.

Ziyao took a look at the operation instructions of the equipment, carefully annotated the German in English and Chinese, and then opened this set of equipment and took out the prepared ones.

Number one: Su Jiani's hair;

No. 2: Su Wenchang's hair;

Number three: own hair.

The three samples are then placed on the workbench to begin extracting the hair follicles from the lower part of the hair.

DNA extraction began, followed by DNA purification to remove impurities, a large number of replication amplification on the PCR instrument, polyacrylamide gel preparation, electrophoresis, sample loading, staining, color development, genotype interpretation, and when the three sets of data were displayed in the analysis table on the computer, all three of them came to the display.

Looking at a string of data and graphs, even those two people who don't understand can see that No. 1 and No. 2 have nothing in common, No. 2 and No. 3 are almost completely consistent, and the conclusion given by the same equipment is also like this, No. 1 and No. 2 and No. 3 are not related, and No. 2 and No. 3 are father-daughter relationships.

Zi Yao calmly typed out the report and bound it into a book, Bai Xunan came over and hugged Zi Yao after being shocked, "It's okay Yanyan, we will find out what happened, and we will also find evidence!"

Although Professor Sun didn't know what they were talking about, he also knew that this report was very important to the two of them, and took the report and solemnly signed and sealed it on the last page, which is difficult for a scientific researcher in charge of teaching to do.

The two left the medical school, to be precise, Bai Xunan finally snatched Ziyao out of Professor Sun's hands, because Professor Sun's questions were one after another, the two chatted for a whole day, and the more they talked, the more speculative they became, Professor Sun directly made a decision, saying that he would find the principal to rob people after the school started.

Frightened, Bai Xunan hurriedly pulled Zi Yao away, Bai Xunan found a very good Western restaurant outside to invite dinner, but Zi Yao pouted, she liked Chinese cuisine with thick oil and red sauce the most, but seeing Bai Xunan wanting to take care of herself, she still couldn't help but didn't say it.

They chose a location by the window, and the dish was delivered after a while, the medium-rare steak was fried just right, the black pepper sauce was extremely rich, Zi Yao elegantly cut a piece and tasted it, not to mention that it was not bad, the meat was delicate and tasteful, and Bai Xunan was happy to eat it when he saw that his cousin was satisfied.

The night outside the window was already very thick, and after a while, the revolving door of the restaurant turned again and four or five men and women came in, talking and laughing and walking in, a man in a sky blue suit with sunglasses on his nose suddenly broke into Zi Yao's eyes, Bai Xunan turned his head to look at the familiar voice.
