(Tsunade)
As for tsunade she went to the hokhage office .it was the day when she had kicked out the guards.as soon as she went to the hokhage building she directly went to the hokhage office even some anbu ninjas tried to stop her .as soon as hiruzen sarutobi (third hokhage)saw this he stopped anbus and let tsunade to have a seat .
hiruzen asked "why did you sent away the guards from the senju house you know right they where there for your safety right"
Tsunade :"sensei you can shut the crap even you know that they where all spies sent by danzo and i didn't want them to be snooping around my house and don't send any guards to the compound the senju clan is strong by itself" After saying this tsunade went away without even giving hiruzen a chance to talk at all.Seeing this hiruzen sighed and took the smoking pipe and started smoking while looking out of the window and thinking something.
Then tsunade came back to house and saw Ren practicing wood chakra control. she then went to Ren and told him about her doubts and conclusions that "Ren after the death of first and second hokhage and the senju clan has been losing the clan members in various different suspicious way whether dying in an easy mission or in wars everyone of the clan is died now except us .i know that other village tremble in the name of senju .so many died in hand of other village but they where never killed in a one on one but always in an unadvantageous way where enemy overwhelmed in desperation to kill us. That is not the problem I'm proud of my clan but the problem is believe that there were also hand of people within our village itself to bring the downfall of our clan so don't ever listen to the words of konoha elders and hokhage and I will always be there to protect you ".
Author note:
[(hiruzen,danzo,homura and koharu ) hiruzen and his team of ninja friends from First great ninja war]
After saying that tsunade looked gently at Ren and then went away .after tsunade went away Ren went back to training but in truth he already knows this danzo being scared of senju power asasinated some of them and gave them wrong info on some of the missions and third hokhage knowing all of this choosed to be quiet about all this incident. So even if tsunade had not told him about this Ren would have definitely not believed in third hokhage and elders words .if he ever met them he had planned to act like just a normal child in front of them untill he gets the necessary power.
Then Ren went back to training his wood chakra control like this time passed.
Time skip (six months)
...
...
....
During this six months Ren was finally able to accomplish what he wished to got completed control over wood chakra now he easily can bring out the root of any tree and make it act as he wish whether it be to attack line stabbing or grabbing by twisting of roots and also to defend to take any attack like shruiken or kunai.by the way during all these years in Naruto world Ren also got proefficient in shurikenjutsu and also use of kunai as it was basically a part of his daily exercise.
Tomorrow will be the day of academy and first time when he goes out of the senju compound. Remembering what all he did in this world for six years . Mastering the senju taijutsu,water chakra control ,earth chakra control and finally wood chakra controll ,shurikenjutsu and others chakra control exercises now basically we can say that my foundation is perfect now the only thing left is to learn some badass jutsus and to dominate this world "hahahaha".
Ren was now basically perfect in taijutsu ,perfect foundation for ninjutsu and as for genjutsu Ren is basically immune to this as when you are under you will be disconnected from the world and if any genjutsu was used on Ren he can easily get out of it has when he is under genjutsu he will be disconnected from his surrounding which basically means no natural energy and with his strong mind and body connection of senju no one can put him under genjutsu .
well except for mangekyu sharingan and other strong ones but the can also quickly break out of it and in future when he gets perfect sage body he will basically be immune to genjutsu.....
