4 Improving bloodline 1

"So you're telling me that this Momoshiki guy took your brother's body and killed your whole family?" asked Kushina to jiraiya. 

 

"Yes, not only did he kill my family he also destroyed all the ninja villages and any being that could use chakra" Jiraiya had a pained expression as he spoke 

 

After Jiraiya's technique ended they had been talking about the events of the future for an hour. 

 

"hey, hey "Kushina said while putting on a mocking look "you mentioned your girlfriend several times while telling us about the future, but you never said her name." 

 

Jiraiya started sweating and his face turned red "It's just that that's a delicate matter" Jiraiya said as he tried to 

 

"Come on it might be so delicate that you can't say it" Kushina put her hand on the while thinking "hmmm" 'unless' she put on a surprised expression "Are you gay????" Kushina said as she pointed at him. 

 

"Noo, I'm not gay it's just that..." said jiraiya while scratching his head. 

 

Taking a deep breath Jiraiya stopped hesitating and looked at Kushina with determination "My girlfriend is..." Kushina looked at him expectantly

"My..." Jiraiya said slowly.

Kushina got angry and said "Say it already." 

 "ok ok, I already say it, my girlfriend is Hanabi Hyuga my aunt." 

... 

... 

... 

 

"whaaaaaaatttt "Kushina shouted "yo, your, girlfriend is your aunt" Kushina said shocked. 

 

Minato who was listening to the conversation gave her a proud look and nodded 'that's my grandson' 'way to go' thought minato as he smiled. 

 

"Anyway, I don't have much time" Jiraiya quickly changed the subject. 

 

Looking at his grandparents he continued "I have told you the reason why Momoshiki and the other otsusuki were able to destroy our world" Minato in response said "Yes the Jogan" 

 

"Exactly that dojutsu is the cause of my nightmares and the reason I became obsessed with bloodlines" Jiraiya stood up as he pulled out a sealing scroll "After years of studying bloodlines, more specifically the Dojutsus, Create this" suddenly from inside the scroll came two hermetically sealed glass vials "The creation of my life, something that will allow us to match the game, (the unbelievably wonderful amazing incomparable eye of devastation infinity and god's laser beams)" said jiraiya as he put on a proud face and struck a ridiculous pose in pure jo jo pose style 

 

Minato and Kushina had beads of sweat on their foreheads 'what a shitty name that is' thought Kushina 'He's just like minato with names' on the other hand Minato thought 'that name is awesome, even though the pose is ridiculous'.

"Eeeto Jiraiya-chan, that name is..." Said Kushina trying to find a word that wouldn't hurt her grandson's feelings "It's amazing right, though it lacks more adjectives like hyper mega awesome..." Said jiraiya. "Nooo, Jiraiya-chan that name sucks" Jiraiya hearing that squatted down, lowered his head and put his fingers together, depressed as he muttered under his breath. 

 

"Hey, Kushina I think you went a little far, apologize" Minato said looking at Kushina "Besides the name is great" Jiraiya's ears twitched hearing that and he appeared in front of his grandfather and grabbed his hands "true grandfather it's a great name" "yeah it's great though you could add more words to it like colossal or great" "Yeah and you could also change the word god to something rude like demons" Kushina witnessing this scene got angry and hit them "shut up, those names are crap" 

 

Jiraiya and Minato squatted down with their heads down with a bump their heads. 

 

After a while Jiraiya stood up and cleared his throat 

 

"Following up, after studying the DNA of the Uchihas, Hyugas, my own blood and Boruto's blood. I discovered what parts of their genome shaped the dojutsus, I discovered that DNA alone is not what forms the kekkei genkai in general but a special chakra associated with the bloodline. It is a mixture of DNA and chakra so without one of the two the kekkei genkai will never activate." 

 

"Then an idea came to my mind and if I manipulated the My own DNA by writing the sequence of my own Dojutsu and linked it to the chakra of our bloodline. And that's what I did, for years studying genetics and Fuinjutsu I had finally finished it, but that's when Momoshiki found me."

"You're saying that you created a new dojutsu using fuinjutsu and genetics" Kushina said while scratching her head not understanding half of what her grandson had said. 

"Yes, and I've decided to give it to you" Jiraiya said with a smile. 

 

"Why don't you apply it to yourself?" Minato said worriedly 

 

"It's not possible, for the operation you need a person who is a master in both fuinjutsu and genetics. And I think I'm the only one, at least on this planet, who can perform that operation, plus the subjects have to be asleep." 

 

Before they could say anything Jiraiya continued "I also have something else to give you" Jiraiya spoke while taking out a scroll "this scroll is a bloodline purification scroll. I created it myself while studying bloodlines." 

"As the name suggests it is going to purify the predominant bloodline of the user by expelling all the useless bloodlines from the blood making it pure." 

 

Minato and Kushina were in awe their grandson was a genius, all those who were called genius before didn't even come close to his heels, he was an absolute genius 

 

"So if you use this on me I will become 100% uzumaki?" asked Kushina still amazed "Yes, grandmother in your case you would become 100% uzumaki, but for you I have something special" He said that taking out another scroll "this one is almost the same as the other one, but it is special, this one is exclusive for an uzumaki, it will not only purify the bloodline, it will also strengthen it, but that is not the most important thing." 

"Even if I purify the bloodline with the passage of time and generations the blood will be diluted that's why I came up with a solution. I will alter the Uzumaki blood so that it will always be pure." 

 

Seeing that his grandparents did not understand he continued "In other words the Uzumaki bloodline will always be passed on to the next generation, the Uzumaki bloodline will absorb the abilities of the other bloodline and then discard them. For example if an Uzumaki married someone from the Yamanaka clan their children would be and have all the abilities of the uzumaki clan plus the mind control abilities of the yamanaka clan, but it would be 100% uzumaki in other words the uzumaki clan will absorb the abilities of the yamanaka clan for themselves." 

 

Minato thoughtfully asked "And if the son of yamanaka and uzumaki were to marry a woman of the Yuki clan?" 

 

"He would inherit all the kekkei genkai of the uzumaki, yamanaka and yuki clan." 

 

Minato looked at Jiraiya in shock imagining how strong the uzumaki clan would be in the future. 

 

"And why don't you use it on yourself?" asked Kushina. 

 

"I was going to use it to purify my bloodline, but unlike you grandmother I only have a quarter Uzumaki blood and half Hyuga blood so my predominant bloodline is that of the Hyuga clan, the seal would purify my Hyuga blood by eliminating my Uzumaki blood. If I purified my Hyuga bloodline I would only become a pseudo Otsusuki, since the Hyuga are closest to that clan." 

 

"Let's continue, these seals are single use that is to say once you use them they will turn to dust, but there is a problem to use them you need an abysmal amount of chakra to go purifying the bloodline" 

 

"But don't worry, you will help us right? Kurama"
