Naruto: "Oh bless! Finally. Some progress." It would be only 5 days until school would start so he wanted to be as prepared as he can be for now. He even wanted to start on some powerful jutsus for backup and so he decided to do a massive operation. Naruto made 2020 clones. 1000 of them stay in the ID Create world and separate into two groups. 500 will focus on chakra control and the other 500 will focus on the jutsus called Chidori and Rasengan. Most of the other 1020 clones will be in the real world transformed. 20 of the transformed clones will steal supplies and buy a lot of resources in order to practice the Rasengan. Naruto did ask Cain to do it for him but Cain only said to Naruto to get some exercise done
This was Naruto's grand plan. It is a mix of his idea and from what he saw from the pranking Naruto of another timeline. Of course, he had to be careful about not exposing his shadow clones. With a self-nod to himself, he initiated the plan. The clones being him knew what he wanted to do so they quickly formed groups and started moving out. The plan was now in effect.
Main Naruto went to the Chidori and Rasengan group. He stocked up on water balloons and rubber balls before for this day so he spread it out throughout the entire group. Half the group started on the first step of the Rasengan while the others were learning how to use seals in order to use Chidori. Time passed and eventually, the Chidori group made progress. Because of the flexible wrist and flexible fingers perk, they were naturals at making seals and with the dexterity increase from the swordsmanship training, the speed of making the seals was not that slow at all.
One of the Chidori Clones started making the seals for the Chidori and after he was done, there would be a small spark of lightning in his hand. That small lightning eventually grew and grew until the clone stopped giving it extra chakra to enlarge it but rather keep it in his hand.
From Main Naruto's observation, he sees that this skill takes quite a bit of skill to make and a little more resilience to use it. Lightning is untamable so it makes sense that Naruto had a hard time creating it. Not to mention, elemental jutsus that can take physical form are extremely powerful. Naruto saw this fact from his clone's damaged hand. There was an awful lot of burns on the clones hand as he used it. His face contorted as he tried to keep it in his hand using his willpower.
Naruto: "Stop now. You can vanish. Thank you." The clone nodded and vanished.
[Chidori Level 2, Exp-24%]
Naruto: "Alright Chidori clones, focus on the Rasengan for now. Once I find a way to not damage myself using this Jutsu, we will continue to learn it." The Chidori clones then focused on the Rasengan instead. The original Rasengan clones were already on the rubber ball portion of the training so they decided to help the new clones master the water balloon part first. After the clones caught up to the Rasengan clones, they started practicing the rubber ball portion of the Rasengan with them.
Naruto: "Say, Cain. Is there a way for me to safely use the Chidori?"
[Increase your lightning affinity or increase your skin's hardness or gain some sort of lightning immunity or gain a perk.]
Naruto: "I don't know how to do the first, don't know how to do the 2nd, and lightning immunity sounds like a time-consuming process so I guess I should go with a perk. Maybe the perks can give me all of the three before the perk option. Cain, show me perks that will help with using the Chidori."
-[Lightning God's Blessing]
[One takes the trial of the Lightning God. If one passes then one can gain his or her blessing. Different Lightning Gods give different powers as blessings but lightning resistance and lightning control are consistent is with every blessing.]
-[Storm Tempered Body] (Evolvable)
[Live inside a thunderstorm and take on all the hits of lightning. If a person survives for more than 5 days, then they get this perk. Requires a tough body and high vitality. User will gain lightning resistance which will eventually become lightning immunity as this perk becomes stronger. Evolvable because at the 3rd stage which is the max, user can increase their lightning element affinity.]
-[Hard Skin] (Evolvable)
[Get beaten. Starting from something small like wooden swords to something stronger like metal rods in the future. It must hit all spots in the body in order to have a 100% effect and to gain the perk. Evolvable because one can push their skin to the next level with higher level materials. At the fourth stage of this perk, the user can handle Lava and use that to move on to the next level.]
-[Chakra Resistant] (Evolvable)
[User goes against the Nine-Tails in Chakra in it's quality and quantity. User must fight against the stronger chakra of the Nine-Tails while maintaining the user's own chakra at the same time so that the user does not get devoured for 3 days. As this perk becomes stronger, the chakra of the user will not be affected by Nine-Tails eventually. Currently, 75% chance to die.]
[User goes to another location. That place has different levels of lightning and each color represents how strong it is. User must learn how to use his or her Chakra to absorb the lightning to their chakra pathways and their 361 tenketsu points. Once there, the user must attack the lightning energy in each point and refine into the point. Only when the user can take blue lightning to the pathways and points will he or she gain this perk. Evolvable because of the different levels. Higher levels = user learning to generate lightning, lightning jutsus become stronger and are easier to learn, be lightning proof. ]
-[Lightning Cells]
[It follows the same steps of the Lightning Devourer initially except instead of the Chakra Paths and points, the user uses Chakra to focus on every single cell in the body. As these cells split and make more cells, they naturally carry the lightning energy that they possess. Once the entirety of the user's body has been changed, it will be faster, more reactive, stronger, and will be able to use lightning to nourish itself. Continuous growth.]
-[Lightning Sage] (Evolvable)
[User learns how to use the Sage Mode of Elements. Specifically lightning. Strong Body, Faster Reaction, Piercing Lightning, and Quick Speed are natural abilities. Can also call upon a storm. At stage 10, max, user can use this form indefinitely.]
[And for your curiosity, there are the Animal Sages, Elemental Sages, Weapon Sages, and Energy Sages. The Elemental and Energy Sages are extinct in this world but the Animal sages and Weapon Sages are still alive. ]
[What is your choice?]
