Naruto must have used in vitro fertilization to create embryos to extract embryonic stem cells, on the one hand, considering the premature aging characteristics of cloned cells, and on the other hand, he was a little selfish.

He wanted to take the opportunity to gain access to the Uchiha clan's diverse gene pool.

Although there are differences in purity between the white eyes of different individuals, the function of the writing wheel is very simple, and the writing wheel eye has a unique characteristic, that is, when the three-hook jade writing wheel eye is promoted to the kaleidoscope writing wheel eye, it will produce a variety of different abilities.

If you clone Sasuke's somatic cells and then culture the embryos, the Sharingan cultivated with cloned embryonic stem cells will only carry the same abilities because the genetic code is exactly the same.

And the genetic diversity of embryos obtained by in vitro fertilization of hundreds of millions of tadpoles has greatly increased, which is equivalent to the countless children born to Sasuke and different women, creating a race by one person, and reviving the endangered Uchiha clan!

After screening and further modulation, a wide variety of kaleidoscope writing wheels can be manufactured.

During the Boruto period, Uchiha Shin had already developed a cloned kaleidoscope writing wheel, and transplanted the cloned kaleidoscope writing wheel eye on the big-eyed monster, and it was able to cast spatial abilities such as Kamui.

For this purpose, Naruto exaggerated the dangers of cloned cells, persuaded Sasuke to provide tadpoles, and in the future, he would find another opportunity to buy a batch of eggs from girls from various clans in the ninja world, and quietly help Sasuke revive the Uchiha clan.

Anyway, Sasuke's dream is not only to kill that man, but also to revive the Uchiha clan, relying on his life, I don't know how many years it will take to give birth to a nation, life science can greatly speed up the reproduction of the Uchiha clan, which can be regarded as saving endangered species and doing good deeds.

Naruto's R&D direction is similar to that of Nobu Uchiha, but there are also differences, using embryonic stem cell technology, which can directly create eyes without having to make a group of small children.

As for the "give up offspring" clause, Naruto was afraid that he would get away with it when he made the embryo, and accidentally let the embryo grow beyond the ethical boundary, and he couldn't ruthlessly kill the embryo that had formed a fetal heart and started a heartbeat, so he could only let the embryo continue to grow into an adult and raise it as his own son (or daughter) in the future.

With a parenting expert and early childhood education expert Naruko shadow doppelganger, Naruto secretly raising a few children is not a problem at all.

As a scientist, you must be principled and responsible, which is also one of the most basic moral qualities of scientists.

There are too many cases of life sciences crossing ethical boundaries, and letting Sasuke sign the contract in advance is also for fear that if he really gets a child, Sasuke's sudden fatherly love will break out and fight with him for custody, then it will be a mess, and I don't know how troublesome it will be.

After getting into the habit of planning ahead, Naruto certainly had to take precautions.

……

R&D robots, spiral pill launchers, mass production of white eyes and mass production of writing wheel eyes, this is all Naruto's preparation for the "World Buwu" plan, stockpiling war technology, and when the eve of the war comes, these technologies have matured, and they can be immediately put into mass production, and quickly form a scientific and technological ninja army with an average strength of the upper ninja level.

It takes another week for the genetic samples to be extracted and the embryonic stem cells grown into eyes, which is already the shortest time to achieve when the growth rate of embryos and cells has been greatly accelerated using the Soveilin Cocoon of Life technology.

Without the technical support of the Marvel Universe, it would take at least one or two months or even more than half a year to rely on the cutting-edge life technology in the real world.

This trip to the Scientific Ninja R&D Center, the only thing Sasuke did was to provide a genetic sample, and after the incident, he was not very good, and he looked like he had lost his soul, as if he had been hit hard.

Sakura's perception of Naruto has taken a turn for the worse, and she was still a little admired and admired, but now she is full of disgust, and she seems to hate him even more than in the original story.

Naruto is also helpless, it's all for science, for the glorious future of Konoha!

……

After sending the two away, Naruto immediately began embryo culture, and currently only got Sasuke's tadpoles, and also needed a woman's egg to grow embryos and extract stem cells.

The lack of eggs also bothered him, and now there are many poor smugglers smuggled into Konoha and many of them are young women.

As a billionaire among the Konoha ninjas, Naruto has a lot of money in his hands, and he can hire poor young girls who are willing to do anything for it.

But it's very inappropriate for him to come forward in this matter, so he contacted a former young lady of the Otoshinobi Village, who has a good relationship with him, and often goes shopping with Naruto, who has become a hot girl, and discusses fashion topics together, which is a good girlfriend relationship.

So, the Otoshinobi lady took Naruto's money to help him with this, and two days later sent Naruto hundreds of cans of processed frozen eggs.

Before the official in vitro fertilization experiment, Naruto sighed deeply, and couldn't help but sigh, once he started to study life science, he would be a passerby from now on!

The internal security of the scientific ninja research and development center is in charge of the dragon country, and the Konoha ninja can't get in without a pass, so there is no shadow to watch, if Sarutobi knows that Naruto is engaged in this kind of research, it is estimated that his fate is not much different from Orochimaru, and he has to escape from Konoha and go into exile.

He even understood Mr. Orochimaru a little bit of a third-rate folk science, and even felt that Orochimaru might not be bad in nature, but he just didn't receive a scientific education systematically.

The ninja world is a poor and remote place, there is really nothing, only some special genes have some value, in the ninja world, this ghost place to do scientific research, not from the perspective of life science, really can't find any good research topics.

The extraction of embryonic stem cells was carried out before the gastrulation stage, and in order to see the embryo clearly during this period, with the help of a microscope, Naruto patiently carried out the stem cell extraction, put the stem cells into a petri dish, and began the multiplication of embryonic stem cells.

When the stem cells taken from the same embryo had multiplied to a certain number, Naruto moved them into a small organ cultivation tank, which was like a dragon kingdom medical chamber that had shrunk many times over.

By injecting specific chemicals extracted from embryos into an organ culture tank, stem cells can be injected into eyes.

After a stressful week, Naruto looked at the thousands of jars that filled a space the size of a basketball court, holding eyes, and showed a simple smile that was characteristic of a harvest farmer.

It's just that this picture is really a bit scary, and Naruto's smile is quite eerie, much like an evil smile before the evil scientist wants to do something bad.

The eyes carrying the Uchiha gene have been cultivated, but these eyes are not in the form of writing wheel eyes, and the writing wheel eyes of the Uchiha clan have to gradually "open their eyes" in order to evolve step by step from ordinary eyeballs, single hook jade, double hook jade, triple hook jade, kaleidoscope, and eternal kaleidoscope, with more magical functions.

The eyes cultured through embryonic stem cells are still just ordinary eye forms, and they are not chakras at all.

Naruto touched his chin and glanced at the thousands of ordinary eyeballs with interest, not disappointed at all, which was all expected.

Further research on these eyeballs carrying the genes of the Uchiha family, finding out the rules of writing wheel eye opening, and compiling a set of writing wheel eye opening technology outline, is his real goal.
