The fibrous tissues of the dermis were spread all over the body, and after Yue Xingwen turned into flat ‘fibroblasts’, it could no longer roll like before, but could slide and even slip through the gaps of other cells.
Irregular star-shaped cells glide and travel around the body as if on a skateboard, replicating and splitting in different locations as prompted by the course…
Soon, Yue Xingwen’s fibroblasts appeared throughout the body.
In order to let the students distinguish between the main body and replicates, after the cells had differentiated into a large number, only the main body had eyes, and the other copied cells had only shape and no eyes.
In addition to ‘fibroblasts’, the dermis layer also had ‘macrophages’, ‘mast cells’, and so on. Yue Xingwen had this experience in making fibroblasts, and the next work had become much smoother.
He began to be busy throughout the fetus, like a craftsman sewing everywhere, continuing to build the dermis layer under the epidermis layer made by senior sister Lan.
Time passed minute by minute, Yue Xingwen finally finished the construction of the dermis layer. He was so tired that he slumped in place, did not want to move, and his voice was weak, “Finally, it’s done. It’s more tiring than running a marathon of several tens of thousands of meters…”
Liu Zhaoqing said with a smile, “How can it be so easy to create a child?”
Upon thinking about it, Yue Xingwen said, “Let’s keep up the good work everyone. What’s next?”
Qin Miao said calmly, “Just now, the mechanical voice reminded us that at 7 weeks of pregnancy, the facial features of the fetus begin to appear.”
Lin Manluo said excitedly, “The facial feature, is it my turn? Let me pinch my baby’s eyes, nose, mouth?”
Liu Zhaoqing added, “At this time, the hands and feet of the fetus should also appear, but the fingers and toes have not yet been clearly distinguished, and it will stick together as a small fleshy mass. Look around everyone, is there a channel representing a limb nearby?”
Lan Yarong quickly spotted the surrounding passages and said, “I see it here, just now I saw a bulging mass in the upper left corner, upper right corner, lower left corner, and lower right corner, which should be the embryonic stage of the fetus’ limb, right?”
Liu Zhaoqing nodded and said, “That’s right. Mango, you go to the head to make the baby’s facial features. Senior sister Lan and Xingwen continued to work hard, replicating cells and filling the skin, dermis and muscles of the baby’s limbs.”
Although Yue Xingwen was very tired, he could not afford to drop the chain at this time for the sake of the baby to be born smoothly. He immediately said, “No problem, everyone gets to work!”
As soon as the words fell, everyone saw that the star-shaped Yue Xingwen, just like riding a slide, flying to the position that senior sister Lan had mentioned, coopering with Lan Yarong, constructing the cells of the epidermis and dermis layers of the skin together.
After the construction, Yue Xingwen continued to construct muscle tissue below the dermis layer.
Unlike ‘fibroblasts’, the ‘muscle cells’ of the muscle layer include striated muscle cells and smooth muscle cells. Among them, the striated muscle cells were the most contractive and trapezoidal in shape; the smooth muscle cells were less contractice and spindle-shaped. The striated muscle (also known as skeletal muscle) was attached to the bone, distributed between the bone and the skin; Smooth muscle was usually distributed on the tube wall of the gastrointestinal tract.
The limbs that Yue Xingwen was going to construct, there were a lot of striated muscles there.
As a result, Yue Xingwen turned into ‘trapezoidal’ muscle cells after differentiation.

Everyone soon saw that the flat trapezoidal Yue Xingwen slipped around the fetus’ limbs, and he said while working, “The baby’s arms and legs are so short, curled up, and quite cute.”

Zhang Xiaonian asked softly, “Why the Demon clan? Can’t it be the Immortal?”
Ke Shaobin said seriously, “Because, if the twelve of us are put in a cultivation novel, we would definitely be a villainous great demon.”
Everyone: “……”
Xin Yan said lightly, “Do you want to consider changing your major from the Computer Department to study screenwriting?”
Everyone thought to themselves that Xiao Ke did have a talent for being a screenwriter.
Ke Shaobin smiled and said, “I’m joking, our baby can’t be a demon.”
Qin Miao calmly explained the problem of the tail, “It should be there are atavism characteristics, and the ancestors of human beings have tails.”
Liu Zhaoqing said, “That’s right. In fact, all of us develop tails during embryonic development, a gene left to us by our ancestors, but humans have evolved over a long period of time to no longer need them. As the fetus develops, all organs grow larger and larger, only the tail grows smaller and smaller. At about 3 months of pregnancy, the tail will completely disappear.”
Xu Yishen agreed and said, “The scientific explanation is that the part of the gene that is in charge of tail development shuts down, causing the tail to be unable to continue growing and eventually degenerate and disappear. In other words, the gene for the tail still exists in our bodies, it just isn’t growing when the fetus develops.”
Lan Yarong suddenly realized, “So, it’s like this. I said why there’s an extra tail in addition to the hands and feet!”
Lin Manluo asked, “Is it up to me next? Start making facial features?”
Liu Zhaoqing instructured in a low voice, “The facial features are a delicate work, you should be careful. At present, you can only distinguish the eyes, nose, nostrils, and also the ears. The baby’s eyes are still closed, just follow the course prompts to set them.”
Lin Manluo blinked seriously and said, “Okay, I’ll go then.”
She rolled all the way to the location of the fetus’ face, and sure enough, she saw the eyes, ears, nose, and other markings. Lin Manluo filled in according to the prompt, and asked, “Do you think, the baby’s single eyelid is good-looking, or is it better to have double eyelids?”
Without hesitation, Yue Xingwen said, “I think single eyelids look good.”
Most people liked double eyelids, so why did Xingwen prefer single eyelids? Lin Manluo thought about it and quickly realized, “You mean, a single eyelid like Jiang Pingce’s?”
Yue Xingwen said, “Yes, among the handsome men and women around, double eyelids are very common, single eyelids are special, and they are more recognizable. I think Pingce is quite handsome.”
Jiang Pingce: “…Thank you.”
Xu Yishen smiled deeply and said, “Double eyelids are dominant genes Aa or AA, single eyelids are recessive genes aa, and autosomal genes are inherited. If both parents have double eyelids, the child is most likely to have double eyelids; With both parents having single eyelids, there is a 100% probability that the child has a single eyelid. If one is single and the other is double, all sorts of possibilities are possible.”
The liberal arts students were a little dumbfounded to hear this, but thinking it was awesome although they did not understand it.
Lan Yarong concluded, “That is to say, whether the child will have single or double eyelids in the future is decided in the genes long ago, we can’t just change it, right?”
Xu Yishen replied, “Yes.”
Lin Manluo had some regrets and said, “Okay, then I’ll make the baby’s eyes first.”
Eyes, ears, nose…
Senior sister Lin worked for a while and finished constructing the fetus’ facial features, and immediately after, Liu Zhaoqing began to construct the brain and pituitary gland of the nervous system.
Although the pituitary gland was a small part of the body, it was very important in the participation in the process of regulating hormones throughout the body. Senior brother Liu studied medicine and did not need guidance from others, so he quickly found the location of the pituitary gland and completed the differentiation.
Once again, a mechanical voice rang in their ears, “At 9 weeks of pregnancy, all the organs, muscles, and nerves of the fetus are beginning to work and developing rapidly.”
As soon as this voice sounded, Liu Zhaoqing hurriedly said, “Everyone, get to work! The endoderm classmates are also getting to work, the thymus of the fetus is about to develop, the thyroid will have to be delayed a bit. Zhang Xiaonian, you go to the position of the thymus first.”
Zhang Xiaonian looked confused and asked, “Where exactly is the thymus?”
Liu Zhaoqing said, “Development begins in the pharynx and descends to the anterior mediastinum, that is, the position before the pulmonary artery, aorta and superior vena cava. You go all the way forward and find the large blood vessels that Xu Yishen made, then go up and you should see the mark there.”
Zhang Xiaonian knew nothing about medicine, and after hearing senior brother Liu’s instructions, he immediately rolled all the way forward and indeed saw the mark that senior brother Liu had mentioned above the three veins.
Ke Shaobin said excitedly, “Am I also working for the digestive system?”
Liu Zhaoqing said, “The fetus’ digestive system develops the slowest, you don’t need to rush, first make the embryonic stage of the stomach and intestinal tubes. The liver doesn’t start working until after 13 weeks, the gastrointestinal tract only maintains a simple peristaltic movement.”
Even after the baby was born, he could not eat delicious food immediately, but breastfeeding for a period of time. The baby’s digestive function was very poor, let alone the fetus that basically relied on the mother and blood circulation to provide nutrition.
Ke Shaobin did not need directions and quickly found the location of the gastrointestinal tract.
Xin Yan, together with him, was responsible for the liver, pancreas and other organs.
Zhuo Feng took the initiative to take charge of the respiratory system developed from the endoderm. In fact, when Xu Yishen began to construct blood vessels, he was ready to construct lungs and bronchi, and now receiving the instructions, he immediately began to work actively.
The four students of the endoderm got busy.
Of course, the students of the ectoderm and mesoderm could not be idle.
As the fetus grew rapidly from this week onwards, Lan Yarong needed to constantly fill in the newborn fetal skin and, with each extra bit of skin, she had to run back and forth between the five layers of epidermis, sometimes becoming columnar, sometimes becoming spindle-shaped, sometimes becoming flat cells…
The busy senior sister Lan worked very hard for the sake of the baby’s skin.
It was also not easy for Yue Xingwen, the dermis layer and muscle layer under the epidermis were all his responsibility. Sometimes turning into stars, sometimes becoming trapezoidal, sliding between several layers of passages…
The baby’s sweat glands also began to appear, and Qin Miao processed various sweat glands and sebaceous glands in the dermis layer.
Liu Zhaoqing also had a heavy task, starting from the brain, gradually spreading the baby’s nerve veins around the body.
Xu Yishen began to lay a capillary network, and more and more blood cells were created. Jiang Pingce began to construct ureteral access to the urinary system, and the tissue structure of the kidney also needed to be further improved.
Qin Lu was responsible for some of the connections between the internal organs and muscles, and helped the mesoderm students when they were busy.
With 12 people working as hard as if they were in a factory workshop, the fetus gradually took on the initial shape of a ‘human being’ and the organs, tissues, nerves, and blood vessels of the body were also initially formed.
Then, they encountered a difficult problem. “At 11 weeks of pregnancy, the fetal genitals begin to develop.”
After hearing this mechanical voice, everyone was stunned.
Then, Liu Zhaoqing asked a serious question, “Say, we’ve been working so hard for so long, is the baby we are constructing a boy or a girl ah?”
Xu Yishen said helplessly, “Whether it’s a boy or a girl, it’s genetically determined when the fertilized egg is formed, right? It’s not possible to suddenly change gender halfway through development, 11 weeks, 12 weeks, that’s exactly the stage where the genitals will start to develop, depending on what genitals the baby appears to have.”
Liu Zhaoqing said, “If a male organ appears, it’s a boy, and if it does not appear, it’s a girl. Pingce, aren’t you in charge of the genitourinary system? Would you like to take a look?”
Jiang Pingce replied lightly, “En.” He was in the position of the kidney at this time, quickly rolled over to take a look, and found an embryonic stage’s organ similar to his own, so he said calmly, “It’s a boy.”
Lan Yarong sighed with some regret, “A son ah, he must be very naughty after he is born, I like a daughter.”
Ke Shaobin said, “The library is doing this on purpose, right? Construct a boy, be born and go home. He will climb a tree and get hurt, and we have to save him, right?”
Everyone: “…”
Constructing a child was so tiring, raising a child was even more tiring, right?
Yes, birth a baby it’s only a first step!
Thank you for your translation 💙🤍🤍💙💙
AHAHAHAHAH IM READING THIS WITH MY FAMILY OVER AND MY LITTLE COUSIN (male) JUST FELL FROM JUMPING OFF A PLASTIC SLIDE AND ITS KINDA CHAOS BUT AHAHAH THE TIMING ✋😭
haha since Pingce is in charge of the genes down there, I’m sure he definitely won’t be disappointing when fully grown 😭😭😭
