Sasuke really can't ignore this clause, although the clause says that even if he gets a child, it has nothing to do with him, but when he thinks that if he is left alone, it will be difficult to accept it when he sees a group of children who look very similar to him on the streets of Konoha a few years later!

Sasuke is only twelve years old, and he can't bear the joy of being a father, let alone the terrible consequences of the Uchiha family's bloodline being owned by Naruto and being used by him for experiments.

"What the hell is going on with this one?"

Sasuke handed the contract to Naruto, pointed to the line and asked, "Could it be that there is still a ninjutsu in the Kaleidoscope Writing Wheel Eye Pupil Jutsu that can make others pregnant?" ”

Naruto scratched his head a little embarrassed, glanced at Sakura-chan, who was listening and peeping on the side, and said stiffly, "Sasuke, I knew you might not be able to accept it, but you have to be calm." Life science research in the medical field often encounters ethical conflicts, which is also an obstacle that scientists in the medical field often face. ”

After organizing the language, Naruto tried to ask, "The 'cloning technology' was mentioned in the basic science class of the ninja school, I wonder if you have studied it well?" ”

Sasuke nodded, "I just reviewed my biology class a few days ago, and I said that by extracting somatic cell genetic material and implanting genetic material into egg cells, egg cells can be cultured into embryos and asexual reproduction of organisms. ”

Naruto explained, "Cloning technology is effective for producing a large number of individuals or populations that have the exact same genes as the original individual, but there are also drawbacks, the lifespan of clones tends to be shortened, and the fertility rate also decreases, and this defect is magnified in the environment where ninja chakra particles are full and natural energy is abundant, so I don't plan to use cloning technology in the research developed by Sharingan." ”

A typical example is the intercolumnar cell, Madara Uchiha took a bite of the flesh between the thousand hands of the column, multiplying the lump of meat many times, and also carried out transplantation human trials, which is equivalent to a disguised cloning.

Intercolumnar cells are indeed powerful, but the defects are also very obvious, and the uncontrollability of somatic genetic material is too strong.

Yamato was a child cultured from intercolumnar cells, and of the hundreds of people who participated in the experiment, he was the only one who succeeded in the sample, and the others died.

The intercolumnar cells that Madara Uchiha transplanted to himself are also very frighteningly grown into human faces, which look like human facial sores, and there seems to be no problem in the short term, but after a long time, maybe human facial sores will start to speak, and even become self-conscious, and there is no guarantee of safety.

Cloning was quick and easy, but Naruto, out of more rigorous scientific considerations, decided to use a more secure and natural approach than cloning, so that the mass-produced Sharingan would not have potential flaws.

Sasuke was confused and didn't understand what using the non-cloning technique had to do with having a baby.

I thought that Naruto would clone himself before he would list a "descendant" clause on the contract, but I heard him say that he didn't plan to clone.

"So, I decided to use in vitro fertilization technology to cultivate embryos by in vitro fertilization, and then extract embryonic stem cells for organ cultivation."

Sasuke is still a little ignorant.,He's a late enlightened child.,After a tragedy at home, he suffered a little psychological trauma.,Usually don't think about girls' things at all.,I've been busy cultivating.,Although the personality is gloomy.,But it can also be said to be a very innocent little boy.。

Naruto is different, peeking at H magazines at a young age, developed adult ninjutsu, and never forgot Sakura before graduating from elementary school, and even more so when he was an adolescent, he once sneaked into a bathhouse to peep at Temari and Konoha Shimei, and he inherited the lustful vices of Master Jiraiya.

Seeing Sasuke's confused face, Naruto said humbly, "The R&D center has recently introduced a fully automatic tadpole extraction machine from the Dragon Country. Well, Miss Nurse, please come here, you can take this patient to use the tadpole extractor and teach him how to do it......"

Sakura almost understood, although she didn't quite understand the specific details, but the woman's intuition already felt that it was probably not a good thing for Naruto to deceive Sasuke, so without saying a word, she rounded her arm and slapped Naruto hard in the mouth!

"Indecent!"

……

Naruto was beaten again, covering his face and feeling very aggrieved, and said to the two blind people in frustration: "It's all for the purpose of cultivating embryonic stem cells, embryonic stem cells are cells isolated from early embryos or primitive gonads, and have the property of being induced to differentiate into almost all cell types in the body. ”

Annoyed, he pulled out a medical document explaining embryonic stem cell research, and Naruto continued to explain while showing the data to Sakura and Sasuke: "If you develop a chakra eye, I can't just test it on Sasuke's eyes, he only has one pair of eyes, what if he gets blind?"

I plan to use in vitro culture to cultivate a large number of eyes carrying Sasuke's genes as experimental materials to collect data, which requires Sasuke's embryonic stem cells as the growth substrate of the eyes. ”

"Embryonic stem cells only exist in early embryos, and I can't travel back in time and space to extract Sasuke's embryo when it was formed thirteen years ago, and the only way is to clone or in vitro fertilize to create an embryo carrying Sasuke's genes."

"Once embryonic stem cells are obtained, they can be transformed into cells of any organ, and stem cells can be induced to divide and grow into eyes. It's a lot better than cloning a bunch of Sasuke's clones and gouging out your eyes, after all, clones are human beings, and I'm not a Frankenstein, so I can't do that kind of cruel thing. ”

When it comes to the field of life sciences, there will always be a lot of ethical forbidden areas, and listening to Naruto explain the principles of science, Sasuke and Sakura still feel very uncomfortable and embarrassed.

However, the reason has been made clear, because it would be too hypocritical to refuse if you are embarrassed.

Naruto also made it clear that it is okay to use cloning technology to extract somatic cells to make embryos, but there are unknown defects in cloned cells, research data will be biased, and if there is a medical accident in the process of developing Sasuke's eyes, he will not be responsible, after all, it is the patient's own choice, and the risk can only be borne by the patient.

Although it was very embarrassing, embarrassing, and ashamed, Sasuke could only go to the next room with the measuring cup, and the nurse Naruko was afraid that he was inexperienced, so she wanted to follow up to help explain the specific operation process of the tadpole extractor, but she was innocently punched into a white mist by Sakura......

"Well...... You guys, what a bunch of kids, I'm a doctor, Sasuke is a patient, what's so shy? ”

Naruto spread his hands sanctimoniously and said, "After studying medicine, there are many shameful things, so it is natural not to feel ashamed. When I was studying medicine, I read a medical student's notebook that said that a female student in medical school was in an experimental class to observe tadpoles, but she chased a male classmate for tadpoles! ”

Sakura blushed and smiled at him, smacking another big mouth in his face.
