Tsunade then also started explaining to me how I can also use the seal when activated seals spread from the diamond seal from the middle of my forehead to my entire upperbody.
Tsunade also told me I can even us this chakra to enhance my punched and kicks .to gain super strength similar to her.
I was happy with this technique. As there was no drawback .i already had aton of chakra but using the seal when I run out of chakra in emergency is definetly life saving.tsunade also informed it takes two months two completely full the chakra storage.Although it takes two months to I can use the chakra at anytime evn if it's not completely full.
Tsunade then asked are you ready .to which i said"let's go tsuna ,what is the first thing I have to do".
Then she started explaining it to me .She first gave me a scroll which contained a technique named mind construct to create a space in my mind to store chakra and i t also can also be used to protect my mind from anyone who attempts to read .like me creating a locker with chain locked around my mind .it prevents other from reading my mind until they forcefully push and tried to break my construct .within that time i will be aware of it as the mind construct will be connected to me.
So I took the scroll and started creating a mind construct within my mind near my forehead. I started thinking what should I create later i decided and within my mind created a large sphereical shape which was unbreakable it was full gold in color and hard with only a small sealed door only able to open with my command .
within the spherical world I created a miniature place with natural vegetation some trees,then lakes to finish it up I was not able to create any living beings except for trees and plants .so as I finished it i went to tsunade and told her that I have completed my mind construct .she was not at all shocked as she knew he can do it easily .
Strength of hundred seal was tsunade's creation which she got inspired from her grand uncle tobirama senju 's jutsu the mind construct.
So after Ren completed it . Tsunade began to draw seals all over Ren's body ..(..mm just the upper body.) Ren was feeling a little shy cause all though they lived together. Tsunade has never seen Ren this naked .they both had their seperate rooms and seperate bothrooms and all.Ren did like tsunade .well come on who doesn't like tsunade.
Tsunade saw him blushing but didn't know what to say so she quickly completed the seal after drawing it onhis body with some ink and chakra of kanji.as soon as she finished drawing the last part all the seal started moving and gathered at his forehead to form a diamond shaped seal .in black color.ren was not worried about this being seen as it will be covered behind his ninja head band.
As soon as the seal was completed Ren could feel small amount of his chakra being consumed and getting stored within the mind palace .according to his calculation whenever he is free which is basically at night before going to sleep. he will let at least sixty percent of his chakra into the seal and by his calculation it will be filled within Two months.
(Author note.
From now on there will be two chakra one Ren chakra and other seal chakra .)
Now tsunade started teaching me her chakra enhanced fighting style and I started practicing it with my chakra.
She told me to let the chakra flow through my first and at time of impact to let the chakra out to devastae the enemy.to show this tsunade punched the ground and then the whole training ground was destroyed ,i quickly jumped back and saw there was full of debris and dust and tsunade standing in the middle without any dust on her.
After that she quickly fixed the ground back again with the earth style jutsu. Then she saw me and I started giving it a try and went to a nearby tree and used the chakra enhanced fist on it the tree exploded into smither .seeing this tsunade told him to practice hard and went away.
I then saw my first ,i know there is still lot of improvement I can do and then using wood release I fixed tree ,like it was perfect and nothing happened to it at all,except for the pieces of wood of broken tree still laying around the ground. I then went and continued practicing the chakra enhanced technique....
