Secrets of Shoji Clan

2 years goes by and now Nikko is 4 years old. Children of Naruto World generally get their first introduction to chakra at 2-3 years of age but he still couldn't feel the chakra in his body. As an avid reincarnation manga fan, Nikko knows that he should get something like cheat or system as the compensation but it's bad that he couldn't find anything. So he starts to feel that he has been cheated by Goddess Aphrodite.

But our mc is not a person who will remain as the cannon feeder in this world, so he starts to study other subjects diligently and as the privilege he gets from being the member of clan elder family, he utilizes the clan library to the fullest. He already finds the secret of the Shoji clan's mysterious jutsu.

It is basically a summoning jutsu of all types of animal and elements. Every person who has the gene of the Shoji clan can summon the spirit of animals, birds or elemental spirits directly in their body and use their power. Though it is very detrimental to their health and mental condition, it also has one upside. That is, the members of the Shoji clan have the chakra control of all elements in their body. Believe it or not, they can use Fire, Water, Wind, Earth, Lightning, Yin and Yan releases to a certain limit.

Though they will have to choose elements as the primary so that they can grow in future and integrate their body with the spirit so that they will have good understanding with their spirit summon, but it also very much possible that they will have chance to achieve Six Path Sage Mode naturally, which is not easy for even the mc of main manga Uzumaki Naruto and his rival Uchiha Sasuke.

If one can successfully avoid the effects of spirit summoning the bypass the limit of training one element as primary chakra, he will become the strongest in the ninja world and that is also one of the reason why Hidden Leaf Village (Konohagakure) have some threatening feelings for them and didn't want Shoji clan to totally integrate with the village.

...

After learning the truth about the clan's jutsu, Nikko already tried to create a solution about his absence of chakra. With the help of his grandpa Shoji Menma, who is also the elder of the clan, he tried to forcefully summon a spirit in his body so that he can feel the chakra which will help him to find his own chakra point and feel his own chakra. But after many trial and errors, he still couldn't find it and because of dangerous summoning in his not-readied body, his soul also gets damaged.

But as he has one of the highest soul powers in the naruto world in his age due to his reincarnation and having a soul capacity of a 20 years old, he slowly recovers from the damage. Though his idea proved as a failure, it also gives him some hope as he didn't even think that his body, which doesn't even have any chakra and chakra pathway, could actually become the container of powerful elemental spirit though it was forceful and with the help of another person.

So Nikko decided that he will continue his research on this matter and started looking for study and previous research material which his fellow clanmates conducted. But after nearly 6 months of trial and errors he again failed and this time he was badly injured as he tried to fuse both Yin and Yan elemental spirit in his body to kick start his chakra pathway and it puts his dream to become the invincible and strongest person in the Naruto world.

But as they were saying, 'if god wants, who can interrupt his plan', he suddenly heard a bling tone in his mind. At first he thought he was dying from extreme internal injury he suffers from the spirit trial, but suddenly he heard the mechanical voice, "Creator System integration is starting. 10..9..8..7..".
