After the headache become less but the scenes came to him became more frequent but even then he ignores it. Now that he learn how to read he became loved with the books so he started to read the books of Sarutobi family library. He started to learn about the world , learn it's geographical stats , about hidden villages, about the kages , shinobi but the knowledge he gain more superficial. Even though he didn't mind as in mind he is child only. Then one day in a book he learn about chakra and he felt intrigued after reading the content he felt tired become sleepy so he slept on floor. At afternoon when he wake up from the nap he saw his grandpa stood beside him looks at him interestingly. When he his grandpa he said" grandpa , what is shinobi? What is chakra, what is hokage..?" Then hokage said" wait. Wait.. slow there little itsuki I will tell many thing but why are questioning me this?" Itsuki" grandpa I read this things in some book of the library, I think it is interesting" ok, Hokage" I will tell you. First you should know there five hidden villages in this world right. Every villages have 2 type citizen normal citizen and shinobi. Shinobi are that protect the village . They also have incretable power that generate from their body with this they can do jutsu's. As for chakra every human have chakra in them. Chakra are 2 type physical chakra, spritual chakra.
Chakrais essential to even the most basic technique,it has become a form of life energy that all individuals produce to some degree; those who run out of chakra will die. Produced within the "chakra coils" that mainly surround and connect to each chakra-producing organ, the energy circulates throughout the body in a network called the "Chakra Pathway System",Certain groups, such as shinobi, have learned to generate more chakra and release it outside their bodies through pressure points called tenketsu in order to perform jutsu.Chakra is created when two other forms of energy, known collectively as one's "stamina", are moulded together. Physical energy is collected from each and every one of the body's cells and can be increased through training, stimulants, and exercise. Spiritual energy is derived from the mind's consciousness and can be increased through studying, meditation, and experience. These two energies becoming more powerful will in turn make the created chakra more powerful. As for hokage he is strongest shinobi in our village . There also kazekage, mizukage, Tsuchikage, raikage In other four hidden villages. After telling everything Sarutobi look at itsuki's eyes as he knows his grandchild is way too much intelligent for his age. He more intelligent than 7-8 years boy even then it will take some time to digest the thing that he told to Itsuki. After seeing the bright eyes and intelligent look hokage departed from there without disturbing him. So Itsuki thinking about chakra , shinobi, Hokage without noticing that his grandpa long since departed. Then after some time he sleep on the floor. Then some time later hokage came take itsuke to his bed, covered him with blanket. When turn to depart from the place he notice that Itsuki chakra has high chunin level, so touching his brows he tighten the energy suppesion seal. At the same time thinking to himself what he should de about it the he decided he will starting itsukis training after 2nd year birthday.
Next after waking up from the bed after the breakfast Itsuki started to thinking about the knowledge his grandpa told him . He facinated about it and think he will ask his grandpa to teach him the jutsu so that he can became very strong protect his family and grandpa.
At the afternoon when his grandpa came he said" grandpa tech me jutsu, want to become a shinobi, strongest shinobi " but hokage" why did u want to become shinobi" , Itsuki" I want become strongest shinobi so that I will be able to protect grandpa , uncles" , Hokage said " ok, not now after your 2nd birthday" , Itsuki" why", Hokage" no means no, but you can run in the courtyard, it will help you to build your stamina, but don't do this more than 2 hours" , Itsuki " ok".

He became very handsome with dark blue hair, light blue eyes, because of light training and his fast growth he look like 5-6 year old. He also become more intelligent, mature for age. Today although his birthday because of the over work of hokage they didn't invite anyone just did it simply.
At the evening hokage came and wished him give him a new cloth. Then Itsuki said " grandpa can you start to training me, now that you promise me" Hokage" ok", he became very happy and excited and started to laugh , seeing this hokage became happy.
Ok then itsuki said Hokage" from today onwards for next 6 months you do stamina training but not 2 hour but 4 hour and don't question me why just do it".
Time skip( six month)
Itsuki become more intelligent and handsome also the dream came more frequently. And he somehow feel anxious in his heart but can't tell hi grandpa as he learn it's normal, his instict told him not to tell his grandpa so he didn't tell his grandpa.
His grandpa came said" little itsuki come here" with what he pouted " don't call me little" , hokage" ok , ok, come here I will show you chakra. Then he concentrate in his hand and blue chakra came then said" this is chakra now "because of my higher level of chakra reserve you can see the chakra in this form. Now in human body there are 360 chakra points (tenketsu) from which we can release chakra."
Now try to sense the chakra.
After hearing this Itsuki"concentrate on his mind immediately sense chakra,in his mind, excitedly said" grandpa , I sensed chakra"
Hokage" good, good, our Itsuki is a genius, so Itsuki I need to talk to you about something"
Itsuki"what is it?"
Hokage" from the of your birth you have a large and dense chakra,now at this age you have a jounin level of the,but it's not controlled so from today onwards you will try control your chakra. Then he took a leaf on his hand then first it is floating on the hand then it is dancing Left and right. Said after you complete this I will teach you hand sign."
Itsuki" ok grandpa".
Then his grandpa departed and he started to pump his chakra on the leaf. At first it was a bit difficult but when he get a hang on this ,it gets easy. On the first day he completely floating the leaf left and right. On second day he practices the leaf swirling around his body. In only 5 days he completely master leaf control chakra training.
From the side of the shadow hokage was astonished at the high speed of learning of Itsuki .so he started to change training program of Itsuki as normal means didn't work on him. So he think that he will teach hand sign and stamina training from today.
So hokage" Itsuki!" , Yes" Itsuki", from today onwards you will do light physical training with the 4 hours of running you will some pushup and sit-up training. Also you will practice the hand sign.
After that hokage showed the hand sign to Itsuki" there are twelve basic hand seal( I will write seal for sign), rat(ne),ox(ushi),tiger(Tora),hare(U), dragon (tatsu),snake(mi),horse( Uma), ram(hitsuji), monkey (saru),bird(Tori),dog(inu),boar(I).also when practice this try to sense the chakra movement in the body.
Itsuki"ok, grandpa". After that day his life became more strict. If anyone see him then they think he is monster , normally child his age would play,but he doing 4 hours running after breakfast then physical training,then chakra control practice,then hand seal. Doing this maybe boring for some reason his instinct today him to do this. Like this he spent next half year thoroughly understand more about geography, chakra control, physical training, hand seal practice. He look more handsome and intelligent, about age of 8 years old.
