Reborn in demon slayer as an Uchiha

The Gates and Healing

Last time in reborn in demon slayer a Uchiha

"I can help you if you want to be stronger," I said smiling
"Why would you do that for me"she said
"Why wouldn't I help you," I said
"Here is a book, read everything that is in it, it talks about a technique that I'm going to share with you to help you and your sister because she can't cut a demon head," I said tossing her a book about the inner gates

"What are the inner gates," she said looking at it
"The Eight Gates exist in order to limit the flow of chakra within an individual's body. Ordinarily, individuals can use no more than 20% of their body's full potential, the brain's way of protecting the individual from harming their body through overexertion. With training, individuals can learn to remove these limiters, referred to as "opening"the gates.With each opened gate, individuals are given access to more and more of their body's chakra, thus increasing their physical strength and speed."I said.

Now we continue
"There are 8 gates in total with each gate giving a boost to your body," I said before pausing and continuing "your current body physic is not even enough to get to the first gate, if Gyomei we're to have the technique in considering his strong body he will be able to reach the fifth gate which is the Gate of Limit," I said

"It's a shame really I can't start right now, "she said looking down
"Oh I can take care of the demon slayer that are hurt, I'm a good doctor myself," I said

"What's your proof," she said
"You can watch me for the first hour and decide for yourself if I can do it myself. If I can, you going to train your body physically to get at least to the first gate, "I said

"if you fail" she replies
"Then you going to teach me how to do it while I teach you how to open the gate," I said
"Deal," she said
"It's a deal, "I said
After that, I follow her to the healing area, where we arrive in front of a bloody but alive demon slayer.
"Try your best, but I will intervene if you do something wrong," She said

I open my Sharingan to look at his body. I was able to see inside his body and with the help of my Sharingan. My hand gave a green glow as the wound on the person's chest was slowly closing.

I remove my hands from the person's chest as the pain impression on his face was gone.
"Fascinating," Kanea said

"So I can heal them while I also help you train," I say
"Can you shadow clones also use your skill?" she said surprised
"Yes, they can," I said proudly
"Hm so that why the corp value you so much," she said thoughtfully
After she said that I made 20shadow clone.
"Make 2 groups, the first group heal everyone that needs your help, The rest practice your calligraphy," I said
"Yes, sir," all the shadow clones said before going to do their assigned task

"In now we train you," I said
30minutes later
Shinobi pov
I woke up a while ago because Atoru woke me up from my sleep.
I walked down to the healing area of the mansion to see a bunch of.....Atoru walking around.
I walk next to one and said" where is the main one"
The clone replies "oh he teaching Kane one of his techniques"
"Where are they right now," I asked the clone
"In the training area" the clone reply

Around the training area
I left to find whatever he training my sister in,
In arrive there.
"Not there" I heard my sister's voice, I started to walk faster
"Why are you so rough" I heard my sister's voice again.
I started to walk even faster there till I heard Atoru's voice " your skin is very soft"
I open the door with red cheeks to see that Atoru was just giving my sister a massage.
"Hello Shinobu, "Atoru said weaving at me
"Hoh my, why you are blushing Shinobu," Kanea said

A few minutes later
Mc pov
"So that's why I want you. Shinobu to fight my clone so I know how much training you can handle," I said
"Why were you giving my sister a massage them," Shinobu said
"People outside my clan don't know exactly where the gates are located in how to unlock them. So what I did was very simple, I used chakra while hitting the spot the gate is in while giving her a taste of how it feels like to open each gate. So far we only reached the second gate" I explained myself to her.

"What are the gates," Shinobu asked
After explaining it to her
"And that should help you be physically strong enough to cut a demon head," I said finishing my second explanation of the day

"In why can't you spar with me yourself," she said
"I fought against your sister holding back and I won with no difficulty at all I don't think you are that much stronger than her so a clone should suffice" I explained

"Hey, I put up a decent fight," Kanea said puffing out her chest.
I smiled at her antic and then made a clone.
"If you want to prove me wrong just make the clone poof in I will admit that you are stronger than I thought," I said to Shinobu
"Sure just don't regret it later," she said acting like a kid her age for once.
My clone in her got middle of the arena getting into their stance in preparing for a fight.

A/N I can see it now Gyomei fighting Kokoshibu in keeping up by using the Fifth gate. Rengoku keeping up with akaza while using the third gate, In all the hashira with Atoru jumping muzan while using the gates technique.
I'm getting so many ideas in combos that I can use later on the upper moon using the skill that he gonna acquired
