Well today morning was different after getting freshed up and having breakfast tsunade was waiting for me at the training ground .
As soon as I reached their she began our training by telling me to get warmed up and do exercises same again after grueling exercise i absorbed little nature energy which even tsunade was not able to perceive.
Then after this tsunade thought me the very basic leaf chakra control method where I have to keep the leaf on the forehead and pass through it and balance it and only after few tries I was able to do it .
Which shocked tsunade a lot but after testing it again and knowing that Ren was easily able to do it she then gave him the second form of chakra control technique which is to walk on the tree bark similar to the previous exercise Ren was able to do it for two three steps then lost control but he was able to do it within the evening of the day .
Seeing his speed of training tsunade was flaggerbasted but she was also very happy with it .
Tsunade was now thinking about the second great ninja war where her beloved dan died while fighting and then her only hope if flower her brother nawaki whose only dream was to become a hokhage died while being under orochimaru command due to an ambush of explosives after hearing all this news she wanted to leave the village and lead a solitary life but then there came Ren who brought light back to her life and he is the only person of hope within her life who she wants to protect with everything she can .as she was thinking it Ren approached her and then they ended their training and went back to the house and slept after taking shower and having dinner .
Before going to sleep Ren's body was now accustomed to the small amount of nature energy so from today he also started taking a tiny bit of nature energy daily before going to bed . to calm, cool and strengthen his muscles and body.
Next day again tsunade also thought him the next training method af walking on water after all this tsunade left him went to look out for other works but in truth tsunade was always tired as she being one of the best medic nin was now an old lady of fifty years old due to her using creation rebirth to heal herself and her teammates the other two sanins while fighting against the hanzo the salamander within the village of rain made her loose lot of life force and becoming a 50 year old lady.
After teaching him what to do about water walking technique tsunade went away . Ren was easily able to do it with some mistakes because it was due to his second talent which he selected in the list of available talents during the wish there was only two talents which had perfect within them which he assumed to be the best and strongest and choosed them one being the [perfect nature attunement] and other [perfect chakra control] which is the talent which has helped him alot within this exercises.
(Author note: don't worry about wood release he will get it)
Like this he continued practicing this exercises dialy . Getting up working out absorbing small amount of nature energy and practicing and at night. at time of sleeping doing same absorbing small amount of nature energy and then sleeping.
Time skip(eight months)
....
....
....
..
Like this eight months passed and Ren now is three years old .he kept practicing this exercises and gained complete mastery over the exercises .
Tsunade used to come at random intervals and watch his training and leave again .
Suddenly one day Ren was able understand what was going on with tsunade by his interaction with her and his knowledge about the future that she was feeling weak .Ren himself knows that he likes tsunade alot and she was his only saving grace he has cure for it the nature energy but he cannot force it itself into her without her knowledge as she will definitely feel a foreign energy entering her so he decided to reveal it to her.
One day at the training time when tsunade came to see him he ran towards tsunade while acting like being excited and told her about how he can feel an energy all around the surroundings to her
Tsunade din't get it but then Ren gently tried to push a strand of nature energy by controlling it into her body theough chakra veins then there tsunade felt it and her eyes widened for an entire minute she was silent.....
