Talent + worry and stress= faster result

Last time in I was reborn in demon slayer as an Uchiha

I waited for the food to come and forgot that there was someone next to me.

"Here is what you order"The chef said handing me my food.

I thanked him before leaving the shop, I needed ink like won't of it, seal don't just magically appear ink is use to make it.

So after finding a ink shop and buying more ink than I could imagine I went to find a shop that sold paper.

I spent 900thousand yen in total, yes I spent that much money on ink and papers, is it to much.

Yes, do I care no.

I don't care if u have to spend all my cash I need material to make the seal and a lot of it.

When I got everything I instanstly vanish from spot and appear back at the mansion.

"Time to work on some seals"I said as I walked into my office, I made the ram handsign and created 20clones that started working on the seal with me.

Now we continue where we left off

"You guys know what to do," I said looking at the clones.

They all looked and each other and then all of them took a piece of paper and started drawing some symbol on it, I was familiar with Kanae chakra considering I feel it everyday and so the clones also know how he chakra feel.

The seal that I would be making wouldn't be the seal that I had tatoed on my arm and chest, it would be completely different, while my seal just absorb 50% of the chakra I didn't use at the end of the day, the seal that I will be making for her would have to store my chakra and inject my chakra into her body slowly and make sure her body doesn't try to neutralize it.

Which mean, this seal is going to be much harder, like a lot harder than mine but who care, I went into a cabinet where I took out a sample of my blood and I took out a sample of her blood.

"Time to overuse my eyes"I said as I turn on my sharigan and started analyzing the blood.

My blood was rich on energy chakra, oxygen fiber and seem to be very active while her seem almost like life has been drained out of them.

My goal is to find a perfect ratio from my bloods to her, and when I find I could try and make her body as energetic as me for a while, it won't really be permanent because that would caused her more harm than good. (A/N lets just his blood work like the drugs that the doctor give you to take if you take to much you will die that the same here)

While all my clone were working on seals, I was working on her way to make sure I don't have to worry about her 24/7.

I couldn't neccesalary test it on Kanae, so I tested everything on her blood samples, most of the time something went wrong.

The seal weren't doing much better either but I wanted for the early stage to be done by the time she woke up.

Time-skip

"Atoru wake up"I heard a familiar voice said, I felt like something was shaking me and so I open my eyes, I felt a lot of pain in my eyes but my vision was still great, I had a headache that felt like there was an axe on my head but I managed.

When I fully grasped where I was, I looked up to see a familiar petite figure.

"Shinobu when did you get here" I said as soon as I was able to make out her figure.

"around 5minutes but what happened here"Shinobu said pointing at the mess that was now my office.

"I was working on a seal" I said as fixed my hair, for some reason my hair was standing up and my face looked like something exploded on it.

I could see all that in her eyes.

"What kind of project were you working on"She said still looking at the mess I created.

" a seal that can send chakra into Kanae body without it hurting her," I said before I looked around and I could what she meant, the room was messy as hell, it was covered with paper and storage seal, there was also a lot of empty ink bottles in a corner, but we going to ignore that.

I also noticed that I hadn't even taken a bit out of the food that I had ordered, it was left untouched and I felt hungry looking at it, but before I lost myself to hunger.

I took out the newest model of the seal that I had been working on. It was done.

Shinobu looked at the seal and then said"Doesnt it take you weeks to make that seal,"

"Shadow clones, a lot of shadow clones" I said before I stood up.

"What time is it right now"I said looking at Shinobu.

"It's the next day and it's around 2:30 pm or so right now"She answer.

"Thank you"I said as I dragged myself out of the room.

"and where do you think you going there Mister"Shinobu said as she grabbed me and stopped me from leaving the room.

"I need to put the seal on Kanae before she wake up, so it get used to her before she starts moving again"I answer with bags under my eyes, I looked sleep deprived. (A/N what were you doing)

"Let me help you if I let you go by yourself you may knock yourself out." She said as she started supporting me, I didnt feel like I needed any supporting but as soon as we were halfway there, my limbs gave up on me.

I wanted to infuse them with chakra to force them to go on but there was nothing left.

For the first time in a while, my chakra pool was too dry, It was as if I was trying to take some water out of a nearly dried well.

With the help of Shinobu helping me walk to the room, I managed to reach where I placed her on the bed, she was still sleeping in the chakra that I had given was nearly gone.

'This is way to fast, ' I thought as I saw her skin was once again starting to look pale.

Shinobu once again helped me walked and when i got close enough to her, I was about to place the seal on her arm before Shinobu said"Place it near her heart,"

I got why she said that, if I placed above her heart if this malfunction she might die from chakra overload but if it near her it but not above it, the safety mechanism will activate before it reach it.

I slightly remove the dress that she was wearing just enough so that I could place a flower shaped tattoo in her chest.

After placing it and putting her dress back on, everything faded to black, 'Sleep well' I thought before I fully passed out

A/N The more he want to do something to accomplish something the more his talent will appear to the point that stuff that use to take him weeks take only a day, but he need to really want to do it.

If you wondering why he is so tired from one night of not working, it's because of the mental stress of 50tired shadow clone sending over their experience over to him with each alone having at least 18 hour of experience for him.

Plus he to make new clones everytime the old one die so Chakra exasuthion along with a lot of experience rushing to his head at the exact same time leads to him passing out.
