The days went on uneventfully. The classmates returned to school one after another, and they immediately found that Gu Yu's pursuit of Mu Rongheng did not succeed, because the two kept a considerable distance from each other, never saying a word, or even looking at each other.

This made many classmates gloat, and some classmates sympathized with her, thinking that although she was a little crazy to kiss Mu Rongheng, she belonged to the kind of girl who dared to act, but it was a pity that she encountered an iceberg that would not melt for thousands of years, which was unlucky.

Gu Yu didn't dare to do anything out of character to Mu Rongheng anymore, except for calling him "Teacher Mu" out of politeness, he didn't even dare to give him a smile, for fear that the hot face would stick to the cold buttocks, and he would be bored.

Mu Rongheng is not used to her transformation, she used to smile at herself, no matter how cold she was to her, she also greeted her with a smile, but now, even if she greeted her, her face was as cold as ice.

But he quickly figured it out, Gu Yu is the kind of girl who is very adaptable, and she is very good at adjusting herself according to the environment, so such a change is nothing.

It's also good, she won't pester herself anymore, and each other will be pure!

During the class, Gu Yu actively spoke at all, but Gu Yu did not change at all, and there were many questions.

This time, Mu Rongheng talked about the chemical composition of DNA, but Gu Yu asked a question that had nothing to do with the chemical composition of DNA: "Teacher Mu, I heard that a nurse at the University of Zambia Teaching Hospital has exchanged 5,000 babies in 12 years. If the blood relationship is disrupted, will the child still be able to grow up healthily without knowing it? Is it that there will no longer be any feelings for the biological parents? ”

All the students saw Mu Rongheng's face turn cold, and refused to answer Gu Yu's question for the first time: "This classmate is off topic, let's continue to talk about the main achievements of this branch of biochemistry......

Gu Yuxiang was hit on the head, and since then he no longer dares to ask casual questions, for fear that he will teach himself a lesson in public next.

She actually felt it. Although he inherited his father's DNA, he was detached from his father's upbringing since he was a child, so would he have nothing to do with his father?

Maybe my question belongs to the moral category, not the academic category, so the teacher is too lazy to pay attention to himself, right? But this is not like Mu Rongheng's usual personality, because the questions he asked before were much more brain-dead than this question, and he would answer them patiently.

Now he doesn't even have that patience with himself, it's all the kiss that is to blame!

Mu Rongheng's gaze swept over Gu Yu several times, and he found her listless, and his heart was a little sad.

It's not that he has lost patience with her questions, but that students who are willing to think positively, no matter how naïve the questions are, always take an encouraging attitude.

It's just that this time her question touched on her own sore spots.

He also happened to be involved in the unfortunate incident of swapping babies.

A few days ago, he received a notice from the Public Security Bureau, saying that in the hospital where he was born, a nurse had exchanged a lot of babies out of a sense of revenge, and now that the matter was exposed, he took the initiative to confess his crime.

He happened to fall into the range of babies who were swapped.

At that time, the hospital did not manage babies as strictly as they do now, and many babies did not wear name tags that could not be removed after birth, but simply made a mark, which was centrally placed in the nursery for unified management, and was sent to the mother by the nurse on duty when they needed to feed. Those who do not have breast milk are left in the nursery and fed milk by nurses until they are discharged from the hospital and returned to their mothers.

It was in this process that the perverted nurse did her tricks and feet, using her time on duty, to exchange the sign that the baby could freely remove.

In order to cooperate with the investigation by the Public Security Bureau, Mu Rongheng was also asked to collect DNA.

The DNA test results came out, and he was not the biological son of Principal Mu and Zhang Wen.

This was a shock to him, and it kept Principal Mu and his wife awake at night.

For Principal Mu and his wife, Mu Rongheng is the third generation of single generation, if he is not their biological son, or he can't find his real child, or he finds a girl, it means that his Mu family is broken.

Now that the house is cold, although Zhang Wen hides her emotions well, she still inevitably shows a look of disappointment and anxiety, which affects Mu Rongheng.

He was a little nervous, not knowing what the truth would be next. Who are your biological parents? Which home should I go back to?

He had also been thinking about the same problem that Gu Yu was thinking. How do you answer a question that you can't even answer yourself?!
