After the cell clusters had successfully implanted in the uterus and formed a blastocyst, it would then undergo ‘shedding of layer’ and eventually differentiated into an embryo consisting of ectoderm, mesoderm, and endoderm, which then slowly differentiated to form a complete human structure.
Almost as soon as Xu Yishen raised the question of ‘embryonic layer’, a mechanical voice of the system sounded in everyone’s ears: “In the process of embryonic differentiation, the ectoderm, mesoderm, and endoderm have been formed. The cells of the three embryonic layers cannot be interchanged in the subsequent differentiation and development process, please divide the work in advance.”
Everyone had been standing in several rows, but the next moment, two obvious dividing lines appeared between everyone, dividing their ‘cell cluster’ into three layers: outer, middle and inner.
Liu Zhaoqing suggested, “There are twelve of us, isn’t it better to have a group of four? Ectoderm group, mesoderm group, and endoderm group?”
Yue Xingwen said, “Let senior brother Liu and senior brother Xu decide how to divide it up.” With the presence of the Faculty of Biological Science and Faculty of Medicine’s students, Yue Xingwen did not want to direct this course, and as a liberal arts student, he really did not understand embryonic development.
Xu Yishen seriously gave everyone a popular science and said, “The ectoderm will eventually forms the surface, sensory, nerve, and gland, that is, the human epidermis, such as skin, nails, hair; Sensory system such as eyes, ears, nose; Nerve tissue, such as brain, spinal cord, nerves; and some sweat glands, sebaceous glands, salivary glands, etc. The cells in the ectoderm are generally smaller and the split speed is the fastest.”
It was understandable that the splitting speed was the fastest because human skin, hair, had the fastest regeneration, and once internal organs were damaged, it was very difficult to recover.
Xu Yishen paused and smiled in teasing, “Is anyone willing to go to the ectoderm? Responsible for making our baby’s eyes, nose, hair?”
Lan Yarong took the initiative to speak, “I’m a face person, we are going to have a good-looking baby with fair skin, black hair, and big eyes. I’ll go to the ectoderm and take charge of our baby’s skin.”
Senior sister Lan said that she wanted a good-looking baby, and this view was quickly agreed by the girls.
Lin Manluo said, “I’ll go to the ectoderm too, I’ll manage the eyes, nose, eyebrows and all the other facial features.”
Qin Miao said lightly, “I’ll take care of the sweat glands with you guys.”
Qin Lu originally wanted to go to the ectoderm as well, but she looked exactly the same as her sister, and the two would be indistinguishable from each other if they went to same area together, so she had to stay quietly behind Ke Shaobin, thinking that she would choose later. Xu Yishen asked, “One more student for the ectoderm?”
The next moment, they heard Liu Zhaoqing say cheerfully, “I’ll also go to the ectoderm, and be in charge of the nervous system. The nerves and veins are all over the body, so if anything goes wrong, the baby born can become paralyzed.”
Everyone: “…”
It sounded like a lot of pressure.
Although there were 12 of them, there were too many details to pay attention to in embryonic differentiation, really careless.
The nervous system was indeed very complex and one had to get a professional to take care of it, from the brain, to the spinal cord, to the network of nerves all over the body. If any one nerve went wrong, the corresponding part would not hear the brain’s instructions.
Liu Zhaoqing volunteered to take charge of the nervous system, and everyone was particularly relieved.
The four people in the ectoderm were quickly determined.

Zhuo Feng volunteered and said, “I’ll go to the endoderm, I can be responsible for the respiratory system, I studied science in high school, and I remember some of biology.”
The eyes behind Ke Shaobin’s glasses moved from side to side, seemingly in thought, before saying after a few seconds, “Xin Yan, do you want to go to the endoderm with me? We’ll do the baby’s digestive system together?”
Xin Yan said lightly, “And then raise the baby to be a foodie from an early age?”
Everyone: “…”
Xin Yan’s words always hit the nail on the head!
Ke Shaobin bent his eyes and smiled, “Only with good digestion can the baby absorb nutrients and grow up fast! Don’t forget that our job is not only to get the baby born successfully, but also to accompany the baby to grow up and go to kindergarten. If the child has anorexia, or has poor digestion and absorption, it will be very troublesome.”
Liu Zhaoqing could not help but complain, “Why does Xiao Ke sound like an old father who is expecting the birth of his child?”
Ke Shaobin said seriously, “Although I’ve never been in a romantic relationship in 21 years, it’s an unforgettable experience to have a baby with everyone at the library. I’ll definitely cherish this hard-won opportunity.”
Everyone: “…”
Ke Shaobin was really getting weirded talking like he was pregnant!
Yue Xingwen could not help but smile and said, “THen you go to the endoderm and take charge of the digestive system. I believe that with Ke Shaobin personally taking control, our children’s appetite will be particularly good!”
Ke Shaobin laughed heartily, “Of course. As a foodie, I know very well the structure of the entire digestive system, from the mouth to the esophagus, stomach, duodenum, empty field, cecum, ileum, appendix, colon, rectum…”
Everyone stared in amazement as they heard him, a Computer Department student, actually recite the digestive pipeline skillfully—— What did it mean to be a ‘hardcore foodie’? In order to eat, he actually studied the human digestive system? It was a real no-brainer.
Yue Xingwen wanted to give him a thumbs up, but realized that he had turned into a ball and had no thumb, so he had to wink at Ke Shaobin.
Xin Yan’s voice remained cold and said, “Then I’ll go to the endoderm and be responsible for the liver and pancreas.”
Qin Lu followed closely and said, “I’ll also go to the endoderm. I studied liberal arts in high school, and I don’t know anything about embryonic development. Can I take care of the two structures, the thymus and the thyroid? I’ll ask senior brother Xu and senior brother Liu if I don’t understand.”
Xu Yishen said, “Don’t worry, senior brother Liu and I will help you check overall.”
The ectoderm and endoderm were all occupied, leaving only the final mesoderm.
Yue Xingwen asked, “What about the mesoderm?”
Xu Yishen said, “In addition to the ectoderm and endoderm, the rest of us are all responsible for the mesoderm. In the process of embryonic development, the differentiation of the mesoderm is the most complicated, with dermis, muscle, bone, connective tissue, and the circulatory system, including the heart, blood vessels, bone marrow, lymph nodes and lymph vessels; The end of the various ducts of the body cavity, the plasma membrane layer of all serous membrane and connective tissue of internal organs, veins, smooth muscle in the internal organs, the kidneys and ureters of the urinary system; And the reproductive canal…”
Yue Xingwen’s head was spinning just listening to it, “Are there so many?”
Xu Yishen’s voice showed a hint of helplessness and said, “Yes, the mesoderm has the most types of cells. The remaining four people will have a relatively heavy task, Xingwen, Pingce, Xiao Nian and me; The four of us are responsible for the mesoderm?”
Jiang Pingce calmly said, “No problem, I can be responsible for the bones of the entire body.”
Yue Xingwen said, “I’ll be responsible for all the muscles in the entire body. I’ll leave the more complex cardiovascular system to senior brother Xu.”
Xu Yishen asked, “There are still the dermis and visceral serous layer, is it okay to give them to Xiao Nian?”
Yue Xingwen thought for a moment and said, “How about switching between Qin Lu and Xiao Nian? Xiao Nian tends to get lost, and it will be better to be in charge of separate organs like the thymus and thyroid. He might get confused if he has to run around all over the place.”
Upon hearing senior brother Xu say the structure of the mesoderm just now, Zhang Xiaonian wanted to find someone to change with him, but he did not expect senior brother Xingwen to take the initiative to speak up and help him out. Everyone could not make a mistake in the process of embryonic differentiation, and they were thinking about the baby, anyone making a mistake could cause a fetal malformation. He also felt it would be safer to take charge of an organ himself.
Zhang Xiaonian took the initiative and said, “Senior sister Qin Lu, are you willing to switch?”
Qin Lu readily agreed, “Okay, then I will come to the mesoderm, and Xiao Nian will take care of the thymus and thyroid over here.”
Everyone finally finished dividing the work.
Xu Yishen said, “Okay, let’s start working. Those in the ectoderm go to the outermost passage, those in the endoderm go in, and those in the mesoderm stay put.”
Upon hearing the command, they all rolled towards their own destination.
Everyone took their split balls and rolled them for a few moments before standing in turn in a three-layer structure of the ectoderm, mesoderm, and endoderm, layer by layer in an orderly manner.
The examiner’s mechanical voice sounded again in their ears: “The nervous system begins to develop, forming the brain and nerve tissue of the fetus.”
A brain-shaped spot of light appeared in the ectoderm, and Liu Zhaoqing, who was responsible for the nervous system, quickly rushed over and began to continue dividing, and the originally spherical Liu Zhaoqing also changed significantly due to the differentiation into nerve cells.
Lan Yarong, who was near him, rolled her eyes to take a look and could not help but say, “How did you become like a tree? And there’s still roots?”
Liu Zhaoqing spat, “This is the dendrites and axons of nerve cells!”
Lan Yarong blinked, “Oh, how odd.”
Liu Zhaoqing: “…” He also found it a bit odd too.
Xu Yishen smiled and said, “Don’t be surprised, because the cells of different tissues look different, and we’re going to slowly change from a sphere to all sorts of strange shapes later.”
Lan Yarong asked curiously, “What do the skin cells look like?”
Xu Yishen said, “The skin cells will be more complex, with several layers, each layer is different, there are columnar, polygonal, spindle-shaped, flat…”
Lan Yarong was stunned. “Then, won’t I have to turn into various shapes later?”
Xu Yishen smiled deeply and said, “For the baby to be born with fair skin, you’ll work hard to change a few more.”
Lan Yarong: “…”
A columnar senior sister Lan, a flat senior sister Lan, and polygons senior sister Lan?
Everyone could not imagine a scene like that.
Liu Zhaoqing was busy dividing nerve cells, while everyone else was on standby.
Soon, a mechanical voice sounded in his ears, “At 6 weeks of pregnancy, the primordium of the heart appears and begins to beat.”
As soon as the words were spoken, everyone saw two pipe-like structures on the mesoderm side suddenly merge, and Xu Yishen hurriedly rolled over to take up the position of the heart and began to allow himself to deform, and rapidly split.
With the emergence of cardiomyocytes, the fetal heart was formed.
Xu Yishen was busy for a moment, and suddenly, the sound of a heartbeat resounding ‘thump’ and ‘thump’ throughout the space.
This heartbeat from a fetus made everyone feel very magical. Everyone silently quieted down and listened carefully to the heartbeat from a new life.
Although the sound was weak, it was clearly transmitted to everyone’s ears.
After an unknown amount of time, Xu Yishen smiled and said, “How strange, why do I have a sense of anticipation of becoming a father?”
Everyone: “…”
When they went back to school later, could they tell someone——
Although they had no romantic experience, they had the experience of constructing a child?
Poor students without romantic experience! This part of your life is great time to start your relationship, you can think about it if you want it!
Thank you for your translation 💙🤍🤍💙
Can someone tell me the password? My discord is acting up again…😒
lmfao if i knew xinyan will definitely spoil their babyy (i want more xinyan and shaobin interactionnnnn ueueueue)
Xiao ke is soo cute
