Orochimaru Laboratory.

"Yes, the Hidden Mist Village, Thunder Blade·Ya, and the weather weapon recently developed by the Snow Country have similar effects."

Not long ago, Orochimaru learned about a new combat weapon called the Weather Controller, which was independently developed by the Fuuka clan, a daimyo family in the Land of Snow. Orochimaru was very interested in the technology that could harness the power of natural lightning like the Thunder Blade Fang, so he simply sent out the Root ninjas to steal all the information and data of this weapon, and also stole the information of the climate controller developed by Fuuka Sayayuki.

During this period, they even met their colleagues from the Hidden Cloud Village. The two sides had a tacit understanding and did not fight. The Snow Country did not realize what was happening until it was infiltrated like a sieve.

"Although, if a lightning master is strong enough, he may be able to trigger natural lightning, but..."

Under normal circumstances, the Lightning Release that can draw natural lightning must be an S-level one. In comparison, the holder of the Kirigakure Village's Thunder Blades: Fang only needs to have a certain level of talent to be able to control the pair of swords. If the aptitude is strong, even a jonin can use it to draw lightning from the sky.

The new weapon of the Snow Country has lowered this threshold further. As a price, this weapon has the size of a large building and can basically not be moved with the army. At present, it can only be used as a fortress defense facility. However, this thing that can, in a sense, allow a group of ordinary people to release S-class Lightning Release also made Orochimaru want to copy it and make further improvements.

"Also, I should be able to make a few copies of this pair of thunder swords..."

The power of natural lightning, although not the 'natural energy' generally discussed in the ninja world, is something that comes from nature and will not be affected by the Truth-Seeking Jade or any other ability that can exempt you from ninjutsu attacks. It also attacks extremely fast and its power is expected to be very powerful in the future.

Just then, a small snake came to Orochimaru and told him that someone was visiting.

Then, Orochimaru took a look at the surveillance footage displayed on a computer, then he ran to the door himself and opened it for the visitor himself.

"Isn't this Sasuke-kun? I wonder if you have something you want to do by coming to me at this time?"

"Orochimaru, I need you to do me a favor."

Although Sasuke's mind told him that he was asking for help, as soon as he saw Orochimaru, Sasuke found that he subconsciously became rude again. But Orochimaru really didn't mind at all.

"Oh? That's really an honor. I don't know what kind of favor it is. If there is anything I can do, I will naturally try my best."

"I need a left arm, a left arm that is good enough... I will pay you when I get it done."

Considering that the Orochimaru in front of him was not the one he knew, Sasuke finally decided to promise a reward. He knew very well that the Orochimaru in front of him was not the guy who once wanted to occupy his body, which meant that the other party did not owe him anything.

"Remuneration? I don't need any reward. I just don't know what specific requirements Sasuke-kun has. After all, the term 'good enough performance' is a bit too general."

Orochimaru had no intention of asking for any reward. To him, the fact that Sasuke was willing to take the initiative to come to his experimental table was already a great thing. After all, this was a ninja with the top power in the ninja world. The data on all aspects of his body alone were extremely valuable. Moreover, taking over such a thing would definitely involve research on the genetic level. What Orochimaru could gain while helping was absolutely immeasurable, at least he thought so.

Sasuke thought for a moment, then said, "You should be able to use the cells of the First Hokage to make prosthetic limbs, right?"

"Of course you can, but transplanting an arm with primary cells might have serious side effects. I wonder if Sasuke-kun has a solution for this. If not, I'm afraid I'll need to do a lot of extra tedious work, and it might be too late in these few days."

"There's no need to waste time on safety issues. I'm fine." Sasuke didn't explain too much. As someone who possessed the Rinnegan, he didn't care too much about the side effects of Hashirama's cells. In the long run, that kind of thing could even help him open the second Rinnegan. However, without the direct help of the Six Paths Sage, the process of opening the Rinnegan was too long, and it truly was a 'in my lifetime series'.

Seeing Sasuke so confident, Orochimaru nodded, "Also, I wonder if Sasuke-kun needs to add a function to this arm that can be equipped with the other three magatama Sharingan. After all, the Izanagi technique... Never mind, I don't think Sasuke-kun is the kind of person who would harm his own people."

Seeing that Sasuke's face suddenly turned a little bad, Orochimaru very tactfully rejected this proposal. Although the forbidden technique of Izanagi is powerful enough, it requires the consumption of a three-magatama or even higher level Sharingan every time it is activated. This is undoubtedly a very painful price for people whose darkness in their hearts is not deep enough, because such people would rather die than harm their people because of this forbidden technique, so they can only consume their own eyes.

Then, Sasuke said, "I don't need to be able to use forbidden techniques like Izanagi. In fact, I don't have any overly troublesome requirements. An ordinary prosthetic limb that can use Hashirama's cells is completely sufficient."

Having said that, Orochimaru still planned to improvise. In his opinion, just making a hand like this would make him look too crude, so he would definitely need to do something extra. However, considering Sasuke's expression just now, he didn't plan to say it directly. "Is that so? I think I understand. Come with me. The equipment for studying and storing the cells of the first generation of Hokage will not be placed in a place where it can be easily found."

In this way, the two came to a secret laboratory of Orochimaru. The poor style here reminded Sasuke of the 'Snake Cave' where he had stayed for three years.

At this time, Orochimaru suddenly asked, "Sasuke-kun, I noticed that your Rinnegan seems to have never been closed. Even when it is not in use, it is always covered with an eye patch or hair. Could it be that this Rinnegan is also like Kakashi's Sharingan, transplanted from someone else?"

"...Not at all. This eye belongs entirely to me."

"Then why can't it be closed? This eye looks like it evolved from the Sharingan, right?"

"Evolution... Although the Rinnegan can indeed evolve from the Sharingan, the two are actually two completely different eye techniques. As for my eye, it is indeed special, but the reason why I can't close it is actually because I took a shortcut when I opened this Rinnegan."

It is actually biased to say that he took advantage of the situation. In fact, Sasuke was able to open the Rinnegan entirely with the help of the Six Paths Sage, but Sasuke did not intend to tell Orochimaru about this.

At this time, the two had already arrived in front of an operating table.

"Next, I will draw some blood from you and perform a very complex physical examination on you. Please cooperate with me, Sasuke-kun."

"I will."

At this point, Master Sasuke and his disciple fell into the hands of a snake respectively.

PS: I will update it separately today and make up for it tomorrow.

Sasuke's Samsara Eye has never been closed in the main story, and even in Boruto, there is no state where he actively closes his Samsara Eye (but there is a state where he is blinded).

However, there was a scene in the movie where Sasuke closed his Rinnegan. Many people said that this was a drawing error and no one knew whether it was true or not. Considering that Bozo often covered his Rinnegan with an eye patch and used his bangs to block his Rinnegan, this book temporarily set Bozo himself as not having the ability to close his Rinnegan.
