Walking past this robot laboratory, through the large glass window of the next research room, Sasuke and Sakura saw strange new gadgets again.

In that research room, a few spice girl researchers were fiddling with a very high-tech crossbow, and there were iron cannons in the Hokage world, but the muzzle was not so thick, and Sakura and Sasuke thought of the cannon-like firearm as a crossbow without a bowstring.

The structure of the "tech crossbow" was odd, the muzzle of the gun was more like a large open claw, and a researcher hottie picked up the crossbow, aimed it at the target on the test bench, and pulled the bolt to load.

After loading, the claws began to rotate at high speed, and in the empty groove in the center of the claws, the wind escaped chakra flowed regularly, condensing and converging into a blue air mass the size of a broad bean.

The hot girl researcher pulled the trigger, and the little broad bean flew out at a very fast speed, hitting the target, shattering the wooden target, and even leaving a small spiral damage mark on the wooden stake where the target was suspended, the power of this shot may not be very large, but it is also stronger than the damage caused by throwing kunai.

"That's the Spiral Pill Launcher."

Naruto saw the two of them looking at each other curiously, so he explained: "The user can create a spiral pill and launch it by inputting the chakra absorption spell mark on the grip, but now it has only been developed to this extent, and it can only make miniature spiral pellet bullets, and if it continues to be developed in the future, it will be able to launch more types of spiral pills." ”

"What is a spiral pill?"

Sasuke couldn't help but ask, he was more interested in ninjutsu than firearms.

"It is a kind of Muji ninjutsu that concentrates the chakra and condenses it in a small area and rotates it at high speed to destroy the enemy."

Naruto stretched out his palm, condensed a spiral pill in the palm of his hand, and explained: "This kind of Muji ninjutsu can be created directly through precise control of chakra, the principle is completely different from the scientific ninja bracer using a miniature scroll to seal the ninjutsu, as long as you continue to input chakra, you can infinitely make spiral pill ammunition, and the endurance is much higher than that of the scientific ninja bracer, so there is the possibility of developing it into a firearm." ”

There are many more types of ninjutsu that can be performed using the scientific ninja bracers, but there is a big flaw, once the miniature seal scroll is exhausted, just like a firearm running out of ammo, the bracers cannot be used.

Spiral Pill is the most unique Muji ninjutsu in the Hokage world, no need to seal, only need to control the chakra subtly, in terms of precision, the stability and accuracy of the machine far surpass that of human hands.

The accuracy of ultra-precision machining can reach 10 nanometers, and manual processing, even for the top senior technicians, can reach at most three thousandths of a millimeter, that is, 3000 nanometers, a difference of 300 times.

When it comes to reaction speed, the human nerve conduction speed is 30 meters per second, and the trained ninja can reach 100 meters per second, while the reaction speed of the quantum chip has reached the speed of light, that is, 300,000 kilometers per second, and the gap is not ordinarily large.

Of course, it's just a pill, a skill that a slightly talented elementary school student can master with hard practice, and it doesn't require such a high degree of precision, Naruto analyzed all the data of the spiral pill, and based on this, he designed a claw-shaped bionic hand, realizing the function of mechanized automatic ball rubbing.

As long as the claw-shaped bionic hand enters the chakra, it can automatically rub out the ball, and then use the wind escape accelerator to launch it, to achieve these two functions, plus a chakra absorption and storage grip technology, the "spiral pill launcher prototype" was created.

This launcher cannot be mass-produced yet, mainly because of the limited materials, and the material used to make the claw-shaped bionic hand is chakra metal, which is also a scarce resource in the ninja world, and many of them are used to make high-quality ninja knives and high-quality ninja tools, and the price is very expensive.

However, there may be a solution in the future, and the reason why some rare metals are rare is that the mining and smelting technology are not up to standard, and the production is too low. It's like aluminum, which was once a precious metal, is now very cheap.

The interstellar exploration and mining technology of the Dragon Kingdom is about to be put into use, and when the time comes, the mass production problem can be solved by digging for chakra metal on a large scale.

……

After passing through a few more research rooms, I finally arrived at the medical research area, where the layout is quite a bit of the feeling of the biochemical base of the Great Snake Pill Tian no Kuni Ninja Village, and it is also full of all kinds of bottles and cans, but it is not as gloomy as the underground laboratory of the Great Snake Pill, but it is neat and bright, and the walls are snow-white, more like a hospital.

Entering the medical laboratory, Naruto first asked Sasuke and Sakura to sit down, and two nurses dressed as hot girls were sent out to serve as assistants, and one of the nurses pretended to be hot girls and left for a while, returning with a document in her hand.

"Sasuke-kun, the two of us know each other well, but when it comes to medical issues, the rights and responsibilities still have to be separated, so that you don't blame me for not being satisfied with the process and results of the development of the Sharingan afterwards. Before we begin to extract the genes, please bookmark this disclaimer and medical agreement. ”

Naruto motioned for the nurse Babes to hand the document to Sasuke.

"Of course I'm voluntary, and I can bear any result, even if I fail, I won't blame you!"

Sasuke was a little impatient, not understanding why Naruto was wasting his time on such meaningless paperwork, and he didn't want to look at it carefully, so he picked up the pen and was about to sign.

Naruto patiently persuaded, "Sasuke-kun, I advise you to take a good look at the documents, there are many gray areas involving ethics in medical research, and it is really not easy for ordinary people to accept." ”

Sasuke suddenly thought of the bad thing that Naruto had forced him to learn the "Sister Transformation Technique" before, and decided to take some time and not be inexplicably cheated by this kid.

The content of this document is really a lot, there are more than 30 pages, and the font is also very small, Sasuke read it carefully line by line, it talks about various medical risks, saying that there are some risks, because the patient has a special constitution and the doctor can't control it, and the doctor is not responsible for any problems.

Sasuke, who has studied the basic science of the ninja school, can also understand that everyone has a different physique, and the same medical method is a good medicine for some people, but a deadly poison for a very small number of people, and doctors are not gods, so it is impossible to be foolproof.

He continued reading, and was suddenly caught by one of the "ethical clauses".

"Article 46, in the course of the development experiment of the writing wheel, if a descendant is born carrying the gene of the recipient, the recipient agrees to renounce the legal father-son (or father-daughter) relationship with him...... The by-product of this experiment is owned by Naruto Uzumaki. ”

Sasuke calmed down for a while, read the terms again, and the more he thought about it, the more wrong it became!

How to develop a writing wheel eye and develop a child?

Could it be that among the many magical abilities of the Kaleidoscope Writing Wheel Eye, there is also the one who is pregnant?

It's really hard to say, there are many types of abilities in the Kaleidoscope Writing Wheel Eye, such as the spatial ability Kamui, the psychic ability Betianjin, the time reincarnation ability Izanagi, the Amaterasu that produces the inextinguishable black fire, and the Uchiha Shin's nameless ability to control the object control of the ninja and so on.

Maybe you really have a weird pupil technique that can impregnate each other by staring!
