Du Biao came to the door of the laboratory and was about to push the door in when he heard bursts of laughter coming from inside.

He paused, stopped outside the door, and listened quietly.

"I finally found the reason why the sows miscarried."

"Damn, I know why too."

"What's your reason?"

"I did genetic analysis and found that some of the eggs' own perv virus infection genes still exist, so the resulting embryos also contain the perv virus, and then the embryos disappear halfway through development."

"Then you didn't remove the nucleus of the oocyte?"

"Yes, maybe when the nucleus was removed, it was not complete enough and some gene fragments were left behind, which then infected the embryo."

"It's easy for you to solve this problem. Just clean it up when removing the nuclei. I was in a bad situation. My embryos were infected with other viruses in the sow in the uterus."

"Hey, do you want to find a cleaner sow?"

"That's right. You have to start all over again. It's really hard work."

"By the way, will our entire army be wiped out this time?"

"No, Xiao Gao's sow is fine."

"It seems that he is the hope of the whole village. The results of this experiment will depend on him."

"Tsk, tsk, what did Xiao Gao do to the sow, why should his be fine?"

"Then you'd better ask yourself what you did to the sow and why your sow keeps miscarrying."

"Aren't you the same? Hahaha~"

After listening to these words, Du Biao knew what happened.

It turns out that almost all the cloning experiments done by students failed.

Only one succeeded.

When the name Xiao Gao fell into his ears, he instantly thought of a tall and thin figure.

This student really loves learning and has good practical skills. It is not surprising that he can become the last hope of the laboratory.

Seeing that everyone had almost finished the discussion, Du Biao coughed lightly, opened the door and walked in.

I saw everyone gathering together around a pig pen, observing the only remaining sow inside.

The sow has gained a lot of weight, the black pattern on her back is no longer obvious, her belly is bulging, her head is buried in the trough, and she is drinking milk.

"Teacher Du is back."

As soon as he came in, the students heard the noise, looked back, and hurriedly said hello.

When Du Biao saw all this, he knew what was going on and asked with a smile.

"I heard there was something wrong with your experiment."

"If you have any problems, just tell me and we will solve them together."

The students looked at each other for a long time, and all their eyes fell on Xiao Gao.

Xiao Gao, a tall and thin man wearing a pair of black-rimmed glasses, was stunned for a moment when he heard this, and then he hesitated.

"Teacher, do you understand the pregnancy and postpartum care of sows?"

"This..." Du Biao was speechless.

How could he, a professor of cell biology, understand the postpartum care of sows?

What I usually study and study are sliced ​​cells under a microscope.

If he hadn't received this new project of xenogeneic organ transplantation, his research would not have anything to do with pigs.

Xiao Gao saw that the teacher's face became a little unhappy and he waved his hands in a hurry.

"Teacher, it's okay. We can just study this ourselves."

Seeing that the student was so sensible, Du Biao suddenly felt a little guilty.

I have rarely stayed in the laboratory in the past six months, and I have not been very dedicated to teaching students.

Now that the students are encountering difficulties in their experiments, I can't do much to help them, which is really a bit embarrassing for the students.

He couldn't help but let out a long sigh and said, "Let me be my teacher. I know Professor Wang from the veterinary medicine department next door."

"He knows a lot about the treatment and care of various common animals. I went to him to learn from him."

Xiao Gao nodded repeatedly and showed a happy smile.

"That's great. Now my embryos are the only ones left alive in the laboratory. I'm wondering what I can do to get through the past few months and raise the piglets safely."

Du Biao nodded and smiled, finally regaining a trace of his self-confidence as a teacher.

"Don't worry, leave everything to your master."

"This pig fetus is about to be born. Has the genotype been checked?"

"After checking, it's really surprising. The surrogate sows have the perv virus gene, but the fetuses are 100% free of perv."

"It is simply a miracle of life. This time the virus in the sow did not infect the fetus."

"Most of the mini pigs used in the laboratory have been genetically edited, and some perv virus genes may have been removed."

"It makes sense, but it doesn't explain why the virus in my sow can infect the fetus."

"Perhaps this is the legendary power of maternal love?"

"You might as well say it's metaphysics."

"It has nothing to do with metaphysics. The natural world is so magical and full of all kinds of anomalies. Otherwise, there would be no such thing as genetic mutation."

"Mini pigs are just fine. There is no need to modify genes to limit their growth. Their organs are naturally similar to humans and primates."

"I'm still a little worried about the condition of the fetus after birth. There are too many genetic modifications. God knows what the impact will be."

"Xenotransplantation is like this. It requires large-scale genome engineering. In addition to knocking out perv, which is relatively easy, it also needs to insert a large amount of human DNA into the donor pig genome. It is really unavoidable."

"Fortunately, we have Sanqing's gene editing tools, otherwise it would be difficult to knock out large fragments of DNA and complete our experiment."

"Have you ever studied computer programming? I have taken some elective courses in C and Java. When I was knocking out the pig cell genome, I felt like I was writing code."

"Me too, it's all object-oriented programming, encapsulating RNA, and then changing the DNA code accordingly. It feels like the hand of God."

"If this continues, we will become coders of the new era, but we are coding living things."

"Thank God, we are currently only genetically modifying animals, and it has not yet reached humans."

"I have a hunch that this kind of thing will happen sooner or later in the future. Do you dare to say that in some corner of the world, no one is secretly modifying human genes?"

"The ethics committee will not let this happen. Even the genetic modification of animals is subject to restrictions and cannot be done at will. Modification of the brain and reproductive cells is strictly prohibited."

"Don't think so bad, haven't you noticed? The field of xenogeneic organ transplantation will develop very well in the future. As long as you have a little ability, it will be easy to find a job after graduation."

"Of course, after we finish this experiment, even if you want to join Sanqing, you can do it, let alone other biotechnology companies."

"If my senior brother hadn't proposed this emerging project in the first place, it would have been difficult to publish a paper just by following my tutor."

"My mentor has been led away by his senior brother. I also want to hug him tightly and follow him from now on."

As the students chatted every day, time passed quickly, and soon it was time for the sow to give birth.

The mini pigs used in experiments are different from ordinary domestic pigs. After improvement, their development time is much faster.

In addition, the embryos are artificially implanted. Compared with domestic pigs, which often give birth to more than a dozen, the number is only half, and they can obtain sufficient nutrition for development in the mother's body.

Therefore, it only took less than 70 days for 6 piglets to be born healthy.

The first time, it was divided up by the students who wanted to be parents.

However, there are only 6 piglets, but there are 8 students who want to be parents, which is not enough points at all.

In the end, except for Xiao Gao who got a cub without any dispute, the other seven people could only decide the piglet's ownership by drawing lots.

The fat boy and the pony-tailed girl unfortunately lost the election.

The two troubled brothers and sisters were so angry that they couldn't help but complain about Xiao Gao.

"Xiao Gao, why didn't you put a few more embryos in the first place?"

"Hey, if I had known that only your sow could give birth, I should have given up all my embryos to you."

Xiao Gao also looked aggrieved and shouted that he was wronged.

"It's really not my fault. I originally implanted 10 embryos, but who knew that 4 of them died midway and were all absorbed by other embryos."

"My embryonic mortality rate is quite high. To be honest, I feel incredible that my sow didn't miscarry."

"It seems that you are the chosen one."

The fat boy said sourly. After speaking, his nose twitched, his mouth curled up, and he almost cried.

Xiao Gao couldn't bear it, so he patted him on the thick shoulder and said with great pride:
