Tsunade stood there for a minute. She could feel the nature energy going inside her body cleansing and lightly she could feel her life force which was lost being regenerated .she don't get what Ren had done untill she concentrated and got to know that it was nature energy.
Tsunade:"how did you do it Ren"
Ren:"i don't know tsuna i just can feel this energy all around me I can absorb only little of this and it increases my strength I think"
He put upon a act like not being able to understand what it was and being able to absorb only small amount of it.
Tsunade knowing what it was explained to Ren saying that "nature energy it is also called as natural energy it is an energy within the earth and it's atmosphere it is used to enter the sage mode "
Ren "what is sage mode"
Tsunade "sage mode is an empowered state where you absorb natural energy together with your chakra to form senjutsu chakra which greatly enhances your strength and jutsu's"
After telling him about this tsunade still inquired him about how he felt the natural energy ,is it harmful to him or not .to which i gave her some random answers and consoled her.
Tsunade however was shocked and also happy somewhere that Ren can feel natural chakra and it was not at all harmful to him and now Ren can daily inject a small amount of natural energy to slightly recover her life force if it goes on like this she is sure just within five years she will be fully recovered and be like normal early twenty year old.
Like this the training went on and tsunade then decided to teach him senju taijutsu after all Ren had now completely mastered chakra control exercises very quickly.unknown to her it was all because if his talent [perfect chakra control].
Tsunade decided to also teach him her (strength of hundred seal) just the seal to store chakra and enhancing is technique not the creation rebirth has she didn't want Ren to also loose his life force.
Tsunade didn't tell Ren about it yet but just began training him in taijutsu .she began by teaching him about all its form and the flexible parts of it and how senju strength and vitality can be used within the taijutsu.
Ren then continued to practice daily,he would train ,eat ,absorb little natural energy and also gently pushes a little natural energy even within tsunade chakra every day and this cycle then continues .
Untill one day when tsunade bought two unexpected people within the senju compound they where none other then tsunade's apprentice 'shizune' and her ninja pet the ninja pig 'ton ton' who is just a baby now.
Tsunade then introduced them to me shizune being only six years old and me being three years old .well I was happy i get another person to speak around then I got introduced to the ninja pig who is more important than 'ten ten' within the anime.
I know that in anime this ton ton is very useful it has strong sense of smell and can also perform transformation and other jutsus in the future.
Then tsunade also informed me that shizune and ton ton will stay with them itself .which was a good news to me.as shizune was now six years old she has to now start going to the academy from Tommorow.i sensed shizunes chakra which was just one fourth of mine which means that she should have recently awakened her chakra with the help of tsunade.
Like this the training went on shizune used to come daily after the academy and talk about the academy and how they daily preach about will of fire then to teach about the jutsus and ninja knowledge.
The training went on and training senju taijutsu was very difficult and my body was very young just being three years old did a number on me .tsunade also told me that my body would have to grow to completely master it and make it perfectly fit me.
So for now I just kept hold on it after learning every forms of it .I do daily repeat them to ingrain them within my body .so I will be ready when my body is completely developed to it and I can easily integrate it.
While i was thinking what to do next tsunade came near me and asked "what are you thinking"
Ren:"just thinking what to do now till my body reaches the perfect time for the taijutsu"
Tsunade"don't worry about when your ready I will tell you and there is also a special technique I will teach you for now let's check your chakra nature"...
