After leaving with the satisfaction that he did something for the Uzumaki clan, Naruto goes to his apartment. After putting a Fuinjutsu barrier around it. He summons some of his shadow demons.
Naruto said to them, "Go and search for the Uchiha graveyard inside the Konoha. Report to me after that."
Shadow demons disappear in the shadows. Now he has to wait. So he started studying the advanced Fuinjutsu of the Uzumaki clans. With the help of the system, he quickly learned almost half of it.
Naruto thought, 'I have to wait for midnight for what I am about to do, have to make sure no one should be around me at that time.'
An hour later Shadow demon squad informs him about the location of the Uchiha graveyard. He tells them to keep an eye on it till he comes there.
At midnight he leaves his clone to fool the ninja sensors. After casting invisibility on himself, he teleports to that location. He searched the area with magic to make sure there was no Ninja or Zetsu nearby.
Naruto orders the Shadow demons, "Make sure no one enters the graveyard."
Shadow demons reply, "Yes Lord Naruto."
After they left Naruto started to extract the Sharingan's special energy which resided in the eye and brain of Uchiha people from the corpses of uchiha clan members. Dead men don't have any use of chakra. Few members have large special chakra but looks like they never tapped on it. Most of the civilians of the Uchiha clan also have Sharingan chakra. He got the largest special chakra from the old fools which existed from the first Hokage's time. Maybe they fought alongside Madara.
He stopped for a moment when he saw the name of Izuna uchiha, Madara took his eyes after his death and it evolved into eternal Mangekyo sharingan. Naruto extracted his special chakra. All the special chakra of Uchihas come from the brain which affects their optical nerves resulting in sharingan. All the special chakras are fully extracted by Naruto in due time. But he looked at the last corpses he extracted special chakra from. It was Shishui uchiha. He took his corpse and put it in his inventory.
Naruto has a Necromancer class now. So he can extract chakra from the dead bodies. In this universe, Shishui's body was found later by Anbu, after the Uchiha massacre. And Third hokage kept it a secret. But Naruto identified it as Jane notified him about it. If other people saw it, they would not recognize a rotten and nameless corpse.
All the special chakra is collected in a crystal ball which is glowing. But he needed one more special chakra. He contacted demiurge to come to him.
A black portal gate appeared behind him and his smartest devil servant came out.
Demiurge bows down and asks, "Lord Naruto what is my mission?"
Naruto said, "You have to put a person in deep sleep through your voice."
Demiurge replied, "Yes my lord, I am curious what kind of energy is in this ball."
Naruto said, "It is the source of the uchiha clan sharingan their special mental or brain chakra. You remember I told you about Madara Uchiha and how he gained immunity to the blindness of the Sharingan."
Demiurge nodded his head and said, "He took his younger brother's eyes after his death and implanted it as his eye after he was suffering from blindness by the overuse of his Mangekyo."
Naruto said, "Sharingan come into existence by the mental shock they get which activates a special chakra and it affects the brain and the optic nerve of their eye which becomes red with tomoe marks. When they reach to full potential it becomes three tomoe. It becomes Mangekyo when they lose something very dear in the process. Either they kill them or they get by watching them die in front of them."
Demiurge said, "It is like surpassing their limit by expanding their chakra in the brain. The brain becomes more powerful but the eye cannot cope with the power of Mangekyo."
Naruto replies, "There is a physical limitation for the overuse of anything. But Madara took his brother Izuna's eyes and when he transplanted it, his brother's special chakra which remained in his eyes, mixed with the chakra in his brain, but both brothers have mangekyo so when it mixed their chakra it became eternal mangekyo sharingan but it also cures his eyes. In this third process, he surpassed his eye limit."
Demiurge said, "People are fools to take only sharingan eyes and it never ended well for them. People like Danzo and Orochimaru are fools. My lord how did you figure it out."
Naruto answered, "I saw Kakashi, he cleared my doubt. He has a Sharingan. It was given to him by his friend Obito Uchiha. But it takes a lot of toll on his brain and to conserve his chakra he has to cover the eye. The first thing people think is their Uchiha DNA, which we can say is a half-truth but it is mostly the special chakra that resides in their brain, dormant and activated by shock. like how Uzumaki and Senju have special physical chakra. That's why we have longer lives than other people. Did you understand now?"
Demiurge nodded and said, "So you plan to mix it with your mental energy and become more powerful. You have collected a lot of mental energy. No one knew they had to extract the special chakra from Uchihas. It can be more powerful than other Sharingan by a large margin. Lord Naruto, you have collected a lot of special chakra. If I guess you are thinking about creating a new dojutsu for yourself with this much special chakra."
Naruto replies, "Yeah, you can say that. Now we have work to do."
Naruto and Demiurge are now standing in front of Sasuke's house. They entered his house without disturbing anything. Demiurge has masked Naruto's and his presence. Now they are standing in front of a sleeping form of a tired Sasuke.
Demiurge used his voice control and said, "Go to a deep sleep. You will not feel anything."
Naruto with a satisfied expression said, "That much will be enough Demiurge."
Naruto takes out that same crystal to collect his Sharingan chakra. Naruto puts his hand on Sasuke's head. And starts to drain his special chakra from the brain. It is much larger than anyone else he has seen today.
Naruto said, "Done, now you can command him to wake up tomorrow early in the morning."
Demiurge used voice control and said to Sasuke, "You will wake up tomorrow, early in the morning. Your body will not remember what happened to your energy."
Naruto said to Demiurge, "Now we have one more graveyard to drain Demiurge."
Demiurge looks puzzled and asks, "Which one my lord?"
Naruto replied, "Hyuga of course, I just changed my mind about just having Sharingan chakra now I also want Hyuga's special chakra."
Demiurge said, "Yes my lord. One question, If you can answer for my curiosity."
Naruto said, "Tell me your question."
Demiurge curiously asked, "You didn't ask Shadow Demons to search for it. why?"
Naruto smiled and replied, "Because the Hyuga clan believes sealing the Byakugan is enough to keep others away from its power. So you can say they lack the security there. Even when I was a little kid I went inside there and I know the exact location."
Naruto summoned his Shadow demons to go there first and look out for any uncertainty.
Naruto questioned, "Did you prepare for what I said earlier?"
Demiurge answered, "Yes lord, we have prepared a place for your pets and the future pets that will come."
Naruto said, "After we finish this mission. I will introduce you to Eevees. But be careful they are just babies now. I can summon them anytime. They are just too much attached to me and like to follow me everywhere. I will send them to Nazarick. If someone will ask, I will tell them that I send them to their mother through unsummoning."
Demiurge replied, "Lord Naruto, that boy will now lose his Sharingan or will he ever gain it."
Naruto answered, "He will regenerate the mental energy slowly but he will gain it. After the graduation, he will gain it again. Body and mind never forget their taste of power especially not Uchiha. But he will gain it. But recharging of mental energy which is stolen, takes time."
Both reach another graveyard. It was not empty like the Uchiha graveyard. Guards are stationed.
Naruto said, "Demiurge, you know what to do."
Demiurge with voice control magic said, "Do not resist, your mind will erase any evidence that we have been here. You will be under my control for the time being. Stop anyone who will come to this graveyard."
Naruto takes out another crystal ball and starts absorbing the byakugan chakra from all corpses. After he finished they left Graveyard. Demiurge frees them from his control and puts them to sleep.
Both Naruto and Demiurge are now in Naruto's Apartment.
Demiurge said after looking at seven Eevees, "They are quite beautiful my lord."
Naruto said, "Wait till their evolution and they are dangerous too. Oscar, Max, Charlie, Bella, Ruby, Daisy, and Rosie meet Demiurge. He will take you to my real house. Don't worry I will call you from time to time."
They look sad that they have to be separated from their master. But they agreed.
Naruto added, "I also have another mission for you."
Demiurge bowed and asked, "How can I help you?"
Naruto said, "You are quite a nice manipulator like me. So I think you are the best for this job."
Demiurge said with a gentle smile, "Archdemon like me only listen to you my master and my subordinates. So whom I have to manipulate to your will?"
Naruto replied, "Her name is Anko Mitarashi. A special jonin, her specialty is torture and interrogation. She is the former student of Orochimaru."
Demiurge asked, "Orochimaru whom we are keeping an eye on."
Naruto said, "Yes the same guy. She hates him like a plaque for the curse mark he put on her. He experiments on his students to test the curse mark. You have to tell her that, you can get rid of the soul part of Orochimaru. And alter her curse mark for her benefit. Not only it will help her to get powerful but Orochimaru will not have any control over her. If she asks for my name, tell me the name of KAI UZUMAKI who is very proficient in Fuinjutsu and Demonic arts. It will be me. Tell her the price will not be easy for her to pay."
Demiurge smirked and said, "It is an easy job for me. So what's the price you have set for her."
Naruto said, "Her life, after all, I am the one who can remove or alter her curse mark all alone. She has to work for me undercover and live her life as shinobi of Konoha for the sake of appearance. I want her to surprise Orochimaru. And tell her he is coming in the next chunin exam which is held in Konoha as a competitor. That much is enough."
Demiurge replied, "This is more than enough for me. After I leave your pets in Nazarick with Aura I will immediately get to work, my lord."
Naruto said, "I am very pleased with you. And show her you are more powerful than Orochimaru. That should leave a good impression. Now you can go."
Demiurge said, "Thank you Lord Naruto for such an opportunity."
Demiurge leaves with Eevees through a portal gate.
Now Naruto has collected the special chakra. He is waiting for the right time to absorb it. That is to wait because his small body cannot handle it now. However, it doesn't mean he can't do it.
Naruto thought, "Thank god I still have little power of momonga otherwise I wouldn't be able to draw the special chakra which is lying there in their corpses. After all every matter or object in the universe has energy. I have a special ritual in mind to get a dojutsu of mine hahaha."
After leaving 'Eevees', Demiurge is on his way to his mission. After all, he got a direct mission from his lord.
Anko completed her late night shift for interrogation and left for her home which is on the outskirts of the village. It is nearby from the interrogation department by 5 minutes As soon as she locked the door from inside.
Demiurge greeted her, "Hello Anko Mitarashi, special jonin of Konoha or should I say a former student of Orochimaru."
Anko went into alert mode and said, "Who are you? What do you want from me?" She thought, 'Why can't I feel any chakra from him?'
Demiurge replied, "I am a messenger. My master wants to give a message to you and an opportunity that you wanted for a long time."
Anko's hand is on her weapon. She asked, "Do you work for Orochimaru?"
Demiurge smiled and said, "Why I would work for such a weakling? He is not qualified for my minion."
Anko is ready to attack anytime. But still, she asked, "Why should I listen to you? I don't even know you."
Demiurge said, "That is quite a nasty curse mark you have."
Anko said, "How did you know? Nobody knows about it except Orochimaru or a few people in Konoha."
Demiurge replied, "You are quite impatient now. My master wanted to give a message to you. If you don't listen nicely. I have to make sure, you will listen to every last word of mine."
Demiurge comes forward and sits on the sofa and intentionally shows his silver tail. Anko froze in her place. But still, she doesn't attack.
Anko tried to get more information, "Is that a kekkai genkai or a birth defect."
Demiurge said, "How it can be a birth defect or kekkai genkai, our kind is always born with this from the ancient times."
Anko looked puzzled and asked, "Your kind, you are talking like you are not human."
Demiurge replied, "Forgot to tell you but I am an Arch-demon of hell, summoned by my master."
Anko is sweating but said, "I don't want to die yet and don't want to go to hell."
Demiurge with voice control magic said, "You will listen to me and answer truthfully to me. And lower your weapon."
Anko did as he said. She looked puzzled, so she asked, "What does your master want from me?"
Demiurge replied, "He wants to tell you that he can get rid of the nasty soul piece of Orochimaru which he placed on you inside the curse mark."
Anko said, "He placed a piece of his soul inside this curse mark. I never knew that. Your master can get rid of that. How?"
Demiurge replied, "It's quite simple he is the biggest Fuinjutsu master in this world. He is the master of the Demonic arts. He even has the knowledge of advanced knowledge of Fuinjutsu which wasn't discovered by ninja villages after destroying the Uzumaki clan. Your former teacher may be good at Fuinjutsu. But my master's is number one in Fuinjutsu arts in the whole world. You can say no one can rival him for that place. Even for competing you should have advanced knowledge. My master created his advanced fuinjutsu."
Anko asked with a serious tone, "So he can easily get rid of that nasty soul piece of Orochimaru. And what about curse mark."
Demiurge replied, "He can alter it and give you the full control. According to him, it is a horrible work of bad Fuinjutsu. It is half incomplete. It has the main function of absorbing senjutsu chakra from surroundings. After placing his soul he makes sure to take over your body. The more you use it the more he can control it. The soul piece is corrupting your chakra, not the curse mark itself."
Anko said with some hope, "So I have to get rid of his soul piece to stop this corruption."
Demiurge replied, "Yes, you are right. Even Orochimaru became a Sage by taking a curse mark in Ryuuchi cave from snake sage. But his body wasn't strong enough to hold the power. So he experimented on others when he was in Konoha. Then he got obsessed with immortality to learn all the jutsu in the world. Now he acquired a faulty immortality."
Anko with a shocked expression said, "What!!! he acquired immortality."
Demiurge replied, "A temporary one. My master is angry with him for stealing the notes of Uzumaki fuinjutsu. However, it's basic but he stole which does not belong to him."
Anko questioned him, "Who is your master?"
Demiurge replied, "His name is Kai Uzumaki, he is the best in the world in Fuinjutsu and Demonic arts."
Anko said, "He is a survivor, like the Naruto Uzumaki we have in our village."
Demiurge replied, "He is a man on a mission. I hope you can understand him. His clan is destroyed in front of his own very eyes. Now he wants revenge on all other three great nations that destroyed them. My master was a peaceful boy from a peaceful clan. But what he wants is to return the favor."
Anko said, "But that's insane to go against three great ninja villages."
Demiurge said, "In a year he will be ready to do what he wants. So tell me, do you want to get rid of that soul piece, and want to complete the curse mark with full control of your own? You can become a sage who can rival Orochimaru."
Anko asked, "What does your master want from me?"
Demiurge replied, "Your devoted life. Your loyalty should belong to him alone, not to any village, not even Konoha. Do you accept it? Then I can talk to my master to fix an appointment. He is a very busy man."
Anko thought for some time and said, "I didn't know what I had to do. I don't want to leave my friends. I don't like how people treat me but still, I have friends who supported me in my dire times."
Demiurge replied, "I never told you to leave the Konoha. Even my master wanted you to live here so no one can suspect you. I have one more news for you. Orochimaru will come to the next chunin exams held in Konoha as a participant. With that faulty curse mark which you have no control over, you can't even scratch him. So what do you want to do?"
Anko replied with determination, "I would like to meet Kai sama. I will dedicate my life to him."
Demiurge said, "By the way don't try to betray my master. I know you are not fond of betrayal but my master is not fond of it either. I will come with my master tomorrow. Be prepared."
Anko said, "I already made my decision a long time ago. Whoever will get rid of this curse mark for me. I will dedicate my life to him. Kai sama will not only demolish his work but give me full control and I can become a sage to rival Orochimaru."
Demiurge with voice control magic said, "You are saying the truth.,but still for precaution. You will not remember about this incident till I come to meet you. All the previous effect is released. Now go to sleep."
Anko did as he told her to do. She went to sleep. Demiurge left with the gate. He has other work to do. In the midnight hour many things happened in Konoha and not a soul knows about it. Naruto took both Sharingan and byakugan special chakra for his future use. Even a loyal shinobi has changed after a brief confrontation with Demiurge. She couldn't hide her true feelings to defend against Demiurge. He manipulated her and dominated her true feelings.
