24.

After our retreat to the prison/hospital room of my hideout, we were greeted with the not-so-pleasant sight of corpses. The problem was that I had visited them the night before and they showed no signs of regaining consciousness. Unfortunately, it is very difficult to keep a chakra user unconscious for long time due to their passive resistance to such effects.

 Of course, for such an unfortunate case, I have created the simplest safety system, which simply pumps the air out of the room and then, when no heat is detected in the controlled area, pumps the air back in.

 Primarily it was invented to fight fires in buildings with a lot of papers and scrolls, which is quite a necessary invention (Library of Alexandria approves). And as I see on the corpses they were suffocated, which leads to the only cause for it besides fire, it is a simple pressure mine, most likely someone regained consciousness and activated it.

 Well, I guess that is not my only problem right now. After some disorientation, my mother has also fixed her gaze on the corpses, and I only have a small-time frame to react.

"Oh, my head, where are w... Ichi... it... you..." - She started a little frustrated.

"I just borrowed the bodies from the battlefield, I had to..." - I began to explain as quickly and confidently as I could to divert her attention from the fact that the bodies showed no signs of decomposition.

"But their families, the village..."

"The bodies would have vaporized in an instant if not for me, I collected them after the battle so that our enemies could not lay their hands on them."

"Well, if that is so, but why do you have them here?"

I put my hand on her shoulder, "I just wanted to examine them a bit, the enemy used a very strange technique, I could not find out what killed them, so to give some insight to our commanders I started to examine them. But that is not the important thing right now."

"Ah, yes. Okay, we should free Father first."

"Let's just change the room."

I turned the oxygen pump back on to preserve the biomaterial and we went to the second room in this area. In total there are 2 and a half rooms here. 1 "Hospital" aka prison. 2. where my damn table and a desk with some other furniture are. The third is just a 2 x 3-meter storage or a small wardrobe, mainly used to store various scrolls from food to tools that I have collected all these years.

 "Okay, help me make some room on the table and bring the bucket from the next room, when he is free, I will focus on closing his wound, you should pass me instruments if I need some and take care of the used aid kit."

"Where am I supposed to get you instruments here? Do you have any?"

"In the storage room through that door, you will see a green scroll, everything is there."

"Okay, you do your thing, I will do what I can to help."

The preparations did not take long; my main focus was to recover my chakra and concentrate on transforming and stabilizing it for a tough operation. I noticed that Father's wound went from his kidney to his bladder. But it was only after I opened him up that I could see how bad it was.

"Okay, I'm ready, will you unseal him right on the table with his face up as I need all my chakra for the surgery?"

"Understood, I will start."

 **poof**

After a small cloud of chakra formed, it was unsealed right on the table. 

'Eh, I still haven't managed to make large scrolls without losing chakra after use.'

Of course, chakra is required for sealing and unsealing, as well as the sealing itself. Chakra loss in the in/out process is a fact that depends on the user himself, and as long as the user does not have either perfect control or is not professional with using specific seal, there will be disturbance in the structure of fuin itself, which in turn tries to stabilize itself.

 Usually by taking event more chakra from the user, which is accelerated and compressed a bit more than usual by the system to push excess energy from the structure, which in turn can be seen as a cloud.

This has 2 disadvantages, one is obviously the fact that it can be quite revealing if someone is hiding, that's why ninjas on special missions only get a handful of scrolls, which they should be able to use without special effects. And the more relevant problem is that the process itself damages the seal, so people think that seals can't last long. Even if it is possible to repair them, it is easier said than done. Repairing a seal can take more time than making a new one if the maker knows the process.

 After unsealing, I helped my mind to become clear, one of the most important abilities taught to medics, even in my first world I think it was quite a common state for a professional surgeon, even if they gain it through many years of practice. Well, what can I say, chakra users are cheaters.

"Oooh where are wiiiie *argh*" - Father clenched his teeth in pain.

"Anata." - Mother started to hug him, but did not finish for fear of causing him more pain.

"Stop panicking, it's okay, just a little scraxxxcchhh"

"We don't have time, I need to put you to sleep before I can start working on your wounds, don't resist, I should conserve as much energy as I can." - Even if it is a bit harsh, but we really cannot waste time. He nodded his head slightly. After that, I let him lose consciousness.

 Upon examination, I found that except for the wound that can be closed without too much difficulty, the wound on the chakra channels is too severe for me to heal right now. The only thing I can do is to help them with energy. The control needed to move them is tremendous, of course, if you do not want to damage them more.

The surgery lasted several hours, during which my mother went through all the stages of grief: denial, anger, bargaining, depression, and acceptance. I could not even say a few words without losing my concentration, so the atmosphere in the room was quite tense.

 Luckily for us, it all ended quite well, although he will have chakra problems, but it's better to be alive.

 "I will let him sleep for now so that his organism can heal from the stress of the operation. - I told her after making sure there was nothing else that needed my attention.

"So he will live?" - I asked her with hope in my eyes.

"He will indeed have some problems with his chakra, but I cannot say how serious the situation is." - Her empathic field is a mixture of everything, but at the same time it is pale.

'Well, no surprise, she is emotionally drained. Okay, I need to get her some sleep.'

"Lie down on the couch and I will take care of the rest. - I used a little mental illusion to make her resist less, I know how stubborn mothers can be sometimes.

"But I..."

"It's okay, don't worry, I'll wake you up before he does. " - with a calm and confident voice I lead her to the only couch in the room and sit her down.

"Oh, okay, just for a few hours maybe."

"Yeah, don't worry" - I watched her close her eyes and when I felt her pulse and chakra frequency calm down I stood up.

'Before they wake up, I will take care of my dead bodies or buddies? no, this can lead to some phsiychologic disorder and ninjas with more yin chakra are more under the risk, I should not play with words even just for fun.'
