5 years later
In the 10th year for my hokageship, I declared that no ninja can be promoted beyond academy untill the age of 18 .
This means that the next graduating class will graduate after 5 more years. I privately emphasised to every ninja under me that for the next 5 years, we won't have new graduates, all current ninjas have to work and train hard to make up for upcoming shortages.
Both Hiruzen and I have taken up gennin squads from the last graduating class of child soldiers. This is to encourage other senior ninja to pick apprentices to train up our existing military, since we won't have any news recruits for next 5 years. My ambition is that before the next class graduates, I want to promote all my gennin to chunin.
Hiruzen is busy training the new generation as jonin commander and the jonin sensei of the future sanin.
I myself have taken up a strong gennin team to train. My team is Hatake Sukomo, Might Duy and Shinku Yūhi.
Every day I send three clones to my team to give everyone my best attention. My three clones often work together to train them in team work or for sparing.
My goal is to make them good enough to dump them on Tobirama Sensei at the academy. He only takes the best among chunin for the teacher spots at the academy.
Hatake Sukomo came from a prestigious clan that use chakra channeling with blades. His chakra control and shape manipulation were excellent. My clones insisted on him and Shinku Yuhi training together and sharing knowledge about genjutsu, medical ninjutsu, and kenjutsu.
Although Sukomo was better in theory in all these concepts, Shinku could come up with creative uses for them, making him more suited for genjutsu.
For Might Duy, I would train with him in taijutsu and work out creative ways to avoid genjutsu. Due to his other teammates being trained heavily in genjutsu, they would often have genjutsu based spars. They would each have to come up with their own way to cope with it.
He is already experimenting with 1st gate, gate of opening. When he is completely exhausted, he is still able to push beyond it, almost hypnotising himself into believing he is not exhausted at all.
He is even able to break human limits by self hypnotising himself into believing that those limits don't exist. That is the gate of opening, situated in the left brain. The key to it is self hypnotisation .
Due to pushing himself so hard, he often accumulates stress. This is where rest of my team comes in to practice medicin.
At the end of Every day, both Sukomo and Shinku would come to find an over exhausted Duy, and I would train them in heating/cooling touch medical massage technique and diagnostics medical technique using Duy as the subject.
Even Their d rank missions would be turned into training sessions. They would have cut trees with kunai, paint walls using the tip of their sword as brush, catch missing cat while blindfolded.
I have already told them that they won't be going to a C rank mission until they can do the academy three jutsus without handseals. If I want to ever drop them on Tobirama sensei, this much is minimum requirement.
If they can use the substitution, transformation and clone jutsu without handseals, I would feel much more comfortable letting them go on C rank missions.
Since might Duy wouldn't be able to learn these, I won't be allowing him to go out for c rank missions. This ment that the only way for Sukomo and Shinku to get c rank missions would be by joining and existing team as their back up. Since they are both extremely skilled in Medecine and Stealth, they perfectly fit the role of backup.
Many teams feel lucky to be able to just add a medic to their team. the fact that they can each hold their own in a fight is just added benifit.
It was only after Duy unlocked 2nd gate, gate of healing, that I saw hope for him to progress from d-rank to c-rank missions. I asked him to try to practice substitution jutsu while under the effect of gate of healing's energy.
He might be able to use the gate's healing chakra as chakra to perform the jutsu, and the healing nature of that energy will restore and reshape his blocked chakra pathways.
Everyday, after training his body hard for 10 continuous hours, he reaches the state where he can open the gate of healing for 15 minutes. For those 15 minutes, he tries to cast the substitution jutsu using chakra from gate of healing. My clones then gives him a thorough medical checkup.
The key to gate of healing is self hypnotisation, to remove psychological limits to one's chakra. It allows your body to draw more chakra from your cells than it is healthy for them to lose. This gate, similar with the first one, removed all psychological barriers regarding self preservation, allowing one to Overclock their system.
Poor Duy is so out of it that he didn't have time for even d rank missions, he is always either in heavy training or recovery. I'm even sponsoring his meals.
He lives in Uchiha Jungle with my cats and trains and eats with them . My Other 9 cats can't learn any jutsus yet, so I've been forcing them to phisical train with Duy.
My main summon Kitty is also there, so i teach her some medical jutsus to use on Duy and the 9 lives incarnations. They fight and train viciously throughout the day, leaving my clone and kitty to pick up their pieces.
Kitty and I have also been spending some time with the matriarch cat sage and her consort monkey sage. I've just started to tap into sage chakra, but kitty can't manage it yet. Kitty just loves to spend time with her mother, the cat sage and her latest step - father, the monkey sage and her latest litter of siblings, born from the two sages.
The cat sage tells me that I'm one of the youngest an uchiha has ever become a sage at 25 years old. But now that I'm 30, I'm still only a novice.
My progress is so slow because I'm being extra cautious. I'm not exactly learning the cat sage mode anymore, I'm creating my own sage mode using cat sage mode as the basis.
The cat sage mode gives one enhanced phisical reaction and agility. I used that as basis to create my human sage mode. When it is completely mastered, it will be an even better version of hashirama's sage mode. My human sage mode will enhance the users intellegence, over other common benefits of sage mode.
Soon Duy masters the substitution jutsu using chakra generated by opening the second gate. He has mastered it to such a degree that he can use it even without opening the gate. This is because of healing nature of the second gate removing blockages in Duy 's chakra pathways.
Since Duy was not particularly stealthy, neither a medic, he was not nearly in as much demand as Sukomo and Shinku. I had shown Hiruzen his strength and he had agreed to take him along as backup for any c rank or higher mission his team takes.
Sukomo, Shinku and Duy still often train together with my cats, but for missions they act as free agents to add to any team. I told them that I will allow them to apply for chunnin exam only when Duy learns to do transformation and clone jutsu without handseals.
This had made both Shinku and Sukomo put a lot of pressure on Duy to avoid missions and train his second gate to master the other 2 basic academy jutsus.
