Placenta extract, put simply, is an essence obtained from the placenta of humans or animals. Amongst various claims circulating in the market, this substance is zealously pursued for its miraculous beauty and anti-aging effects.

In my country, the medicinal use of the placenta dates back to ancient times, with 'Purple River Carriage' being the traditional Chinese name for placenta. Historical records even suggest that Emperor Qin Shihuang used this substance in an attempt to achieve immortality.

In the national pharmacopeia compiled after the establishment of New China, it's clearly documented that Purple River Carriage possesses the efficacy of replenishing qi and blood.

However, the claim that placenta extract could beautify and prolong life has been debunked as a myth. In 2015, considering safety issues, China removed Purple River Carriage from the pharmacopeia and prohibited the medical or cosmetic industry from using placenta extract.

Yet, products such as placenta slices and Purple River Carriage capsules derived from human placenta are still recognized as medicines.

In Japan, influenced by Chinese culture and traditional Chinese medicine, placenta extract is also used as a medicine. However, apart from China, Japan, and South Korea, other countries around the world do not recognize it as a pharmaceutical, and even Switzerland, where the rumor of life-prolonging abilities of placenta extract originated, has never used it as a medicine.

As an experienced clinical anesthetist, Jounouchi Hiromi was naturally aware of the existence of this drug. Placenta extract is typically used in injections for liver disease treatment. Although it's rumored that many celebrities use it for beauty treatments, as a doctor, she was of course aware of its actual effects. Whether it could be applied to her own research, Jounouchi Hiromi was uncertain.

"Placenta extract? Hiromi, are you thinking of using this to promote fetal development?" Inside the lab, Chen Yu was monitoring Tashiro Nanaori's medication test and felt surprised upon hearing Jounouchi Hiromi's question, "How did you come up with using this?

Placenta extract, as an extraction from the placenta and with its content, can indeed promote fetal development, but using placenta extract... are you certain?"

"Why do you ask that, Mr. Chen Yu?" Jounouchi Hiromi looked at Chen Yu somewhat perplexed, not understanding why he exhibited such an odd attitude.

"The professor probably mentioned it because of the price of placenta extract and dosage issues," Chen Yu had not yet responded when Tashiro Nanaori, who had been extracting medicine on the side, suddenly interjected, "The price of placenta extract has remained high over the years due to its hyped effects in beauty and health care.

The cost of human placental extract is even more exorbitant, not to mention the expensive sheep placental extract derived from animals.

As for how much active ingredient it contains, one dose of the injection with cell growth factors might not even suffice for a fetus's daily consumption. The daily dose required would be too much."

"How do you know so much about this, Tashiro-san?" Jounouchi Hiromi looked at Tashiro Nanaori in amazement, evidently questioning why she was so well-informed.

"The Tashiro Family's traditional Chinese medicine business involves such products, so I am somewhat knowledgeable about it. Dr. Jounouchi, are you intending to use it to promote fetal development? But in the case of a normal pregnancy, there shouldn't be a need for such a product, right?" Tashiro Nanaori found this strange.

Although some people use placenta extract for female healthcare through injection, there is no precedent for its use on fetuses.

Upon hearing Tashiro Nanaori's question, Jounouchi Hiromi briefed her about Egawa Sae's situation and also mentioned her ideas concerning artificial wombs.

"In that case, I would advise against using placenta extract, Dr.

Jounouchi," Tashiro Nanaori reflected for a moment and offered her suggestion based on her understanding, "While it's true that this substance is indeed an essential extraction of the placenta, containing nutrients and cell growth factors needed for fetal growth and development, it would not make much sense unless used in large doses.

Normally supplying the fetus with nutrients through blood circulation should be sufficient."

"Is that so? Then, what do you think, Mr. Chen Yu?" Jounouchi Hiromi fundamentally lacked experience in such matters. Although she had been inspired by spells, as a newly appointed Blood Knight of less than a month, spells of the Blood School were what she was supposed to excel and specialize in. Yet, she still lacked practical application experience and needed help from Chen Yu.

"I also believe there is no need," Chen Yu considered then rejected Jounouchi Hiromi's idea after a moment's thought, "The primary role of the placenta is still to maintain blood exchange between the fetus and the mother. Since we can use an artificial placenta for blood circulation, we just need to normally supplement the nutrients in the blood.

There is no necessity to use placenta extract." As for the topic of spell application, he did not address it in front of Tashiro Nanaori, merely giving Jounouchi Hiromi a meaningful look.

When Jounouchi Hiromi noticed Chen Yu giving her a meaningful glance, she understood that some things were not suitable to be discussed in front of Tashiro Nanaori and nodded in acknowledgment, "If that's the case, then we'll just remove the fetus from the mother and cultivate it in an artificial womb.

Meanwhile, we'll rely on an artificial placenta for blood circulation to ensure the fetus's nutrition supply... Mr. Chen Yu, do you think there is anything else that needs to be added?"

"For now, I can't think of anything else to add," after pondering, Chen Yu decided to have Jounouchi Hiromi write the detailed plan first, "Write out the detailed plan first, and I'll take a look at it."

"Understood, I'll head back then and won't disturb your work any longer," Jounouchi Hiromi smiled at Chen Yu before leaving the laboratory.

"Professor, is Dr. Jounouchi possibly..." Tashiro Nanaori watched Jounouchi Hiromi's receding figure with hesitancy, her flickering gaze as if she was debating whether to voice her concern.

Hearing Tashiro Nanaori's half-question, Chen Yu just gave her a meaningful look, "What is it? If you think it's a question that shouldn't be asked, then don't ask."

"I'm sorry, Professor," Tashiro Nanaori's face changed slightly upon hearing Chen Yu's words but quickly apologized, then returned her focus to the medication experiment she was working on.

Watching Tashiro Nanaori who continued with her experiment, Chen Yu stroked his chin, recalling that he had once given a healing potion formula to Kyuuzai Ryousen for his father to research and develop, curious about the outcome.

Remembering this matter, Chen Yu left the laboratory to find Kyuuzai Ryousen and inquire about the situation.

However, as soon as Chen Yu left the laboratory, Tashiro Nanaori, who had been immersed in her experiment, paused, her gaze following Chen Yu's departing figure with a complex expression.
