The Calm Before the Storm

Sealed Bloodlines

A four year old Naruto was sitting in the Hokage's office having fun drawing random doodles however when he was finished he had put his brush on the picture and accidentally pushed chakra into the paper. Instantly the brush disappeared.
Naruto started screaming in fear, "What's wrong Naruto?" Asked Hiruzen, Naruto collected himself before responding, "Jiji I don't know what happened, I finished my picture and set the brush down on top of it, then it just, it just disappeared!" Sarutobi started thinking for a bit before something hit him, "Naruto could I see your drawing please?" Naruto nodded and handed the aged Kage his picture, Sarutobi looked at it before responding, "this seems to be a highly advanced storage seal, I can only identify up to level 8 storage seals so I'll have to call someone in about this. ANBU get Jiraiya in here now!" The ANBU got the person name Jiraiya and brought him in.
The man jumped in through the window, "so sensei what did you need me for?" Sarutobi sighed, "what level of storage seal can you identify up to?" Jiraiya thought it was a wierd question but answere anyways, "I can identify up to Uzu... Level three he stopped his sentence and changed it when he saw Naruto in the room, "I see, could you identify what level of seal this is?" He picked up the picture and gave it to Jiraiya, "It is definitely an Uzu seal as you can tell from the unique double swirl going left an right however it's above my level of understanding... Where did you get this?" Sarutobi pointed at Naruto, "the boy was doodling and put his brush on top, He accidentally put chakra in the seal and it put the brush inside." Sarutobi smiled beaming with pride as his surrogate grandson had made something even the best of the best in the elemental nations couldn't comprehend.
Sarutobi then started to panick out of nowhere, "Jiraiya if he is making seals like this unknowingly at this age he needs to learn about seals before he injures himself or others." Jiraiya smiled before handing Naruto a book on basic seals.
"Now Naruto we want you to read this book and do all of these seals however don't put chakra in them." Before he had finished Naruto handed the book back, "Done." Jiraiya looked in surprise before looking over the book, all of it was done perfectly, now both Sarutobi and Jiraiya were gaping like a fish as Naruto just shrugged, "so old man what are you going to teach me?" Sarutobi brought out a book, "I want you to get all of these symbols perfectly to master your calligraphy." Naruto looked at them before quickly wrote each letter before handing the page back, "Sensei you think it could be a bloodline?" Naruto got exited and was bouncing on his heels, "I think it may be part of his mothers side... However than again both were very adept at seals, it's practically in hi blood!" Both looked at the boy, "Naruto can you tell me what these seals are?" Jiraiya put five seals in front of him, there were 2 explosive tags, 2 storage seals, and an eight trigrams seal. "The first and third have a slightly different mix so I would assume they are the same however the first seems older based on the inefficiency of it, the fourth and fifth are also similar however the fifth has a greater capacity and the second is a barrier seal, probably used to seal away chakra based on the design." The adults were shocked at the details he said, as they were all right. "Naruto how did you know that?" Naruto started thinking before he responded, "the first one slowly aloes chakra to go quickly through it, however when chakra is removed it changes to an unstable mix between lightning and magnesium creating an explosion however the third is a little different Jiji, it converts it to a mix between magnesium surrounded by glass then an electric charge hits the centre and it blows up, making it more stable." Naruto started smiling, "Now the fourth and fifth were a little bit trickier as they only have one thing different, however this line right here," he pointed to a line on the seal, "changes how much is sealed as the fourth is straighter it doesn't seal as much in it. Now the second one was the hardest, it was like a storage seal, but the seal doesn't work for any solid objects, so the only thing I could think of to seal in it would be chakra, however I don't know anyone with that much chakra... Hey Jiji?" Naruto asked Sarutobi was still gaping like a fish, "what are the elements needed for Mokūton?" Sarutobi looked at Naruto before responding on instinct, "water and earth Naruto why?" Naruto took out a sticky paper and drew a seal on it that was complex, he then grabbed the letter opener on Sarutobi's desk and cut himself before letting it drip into the ink, he then put the seal on his arm before grabbing a kunai and stabbing it.
Instantly Naruto was on the ground screaming and writhing in pain, soon it stopped and he got up, "Jiji could I test my affinities? I read in a book somewhere that it will show what affinities you have and show if you have an elemental bloodline." Sarutobi nodded dumbly before handing Naruto a piece of chakra paper, "so I just push chakra in I'm assuming?" Naruto pushed his chakra in and what happened surprised everyone, first it cut in half however one half got wet and the other turned to dirt before a sapling grew out of both halves.
"Well Naruto how did you end up giving yourself Mokūton?" Asked Jiraiya, "well the mix of water to earth is something like two to three so I imputed that into a blood/chakra modifier and then stabbed it into myself as drenching it in blood is the only was to activate the modifier." Both adults in the room were dumbstruck, "Naruto could you go home please, I have a council meeting now." Naruto nodded and ran out the door, "Jiraiya call a council." Jiraiya nodded and ran off to get the council.
