Walking through the sliding door Lorien found himself in a small room

  The room wasn't big in size with only one tatami in the middle and a small nightstand next to it

  The only special feature it had was that the windows were reinforced so that no light could come in

  Looking at the bedding Lorien could see a small girl 'asleep' covered by a green-colored blanket

  She had long black hair fading into a flame-orange color at its end, but the most noticeable thing was the bamboo muzzle in her mouth

  Walking slowly towards her, he then sat down next to the tatami and held her wrist under the watchful eyes of Urokodaki who kept monitoring all of his actions attentively

  After all, he promised Tanjiro to keep his sister safe, and even though he didn't think Lorien would do anything to her, he still decided to be cautious and chose to stay close by just in case, so he could react as quickly as possible if needs be

  Ignoring the gazes around him coming from Urokodaki, and Saigai who was also watching curiously, Lorien kept holding Nezuko's wrist as he launched his ability

  [Dream/Reality]: Analyze

  What he needs to do now is know her current situation in detail before he takes any further action

  And what this ability he just used does is analyze Nezuko's situation according to Lorien's thoughts and then make a complete copy of all the data which he'll need later

  Observing the progress and feeling the quick consumption of the Source Energy in his body, a smile appeared on Lorien's face as he remembered the first time he used his ability on a living target

  At the time he had just awakened his ability, and only used it to help Saigai recover, but even doing just that almost nearly exhausted

  But now after such a long period of time and continuous improvement, such consumption isn't much

  It didn't take long for the 'Analysis' to finish as information appeared in Lorien's mind detailing Nezuko's current situation

  And it was indeed as he previously guessed

  There indeed exists a conflict between two opposing forces inside her body, one of which is currently overwhelming the other

  But it appears that the other one (Flame/Positive) is getting stronger and stronger by the second, while the one who is at the top right now (Death/Negative) is losing ground

  This may be because Nezuko hasn't consumed any human flesh since becoming a demon which kept weakening this 'Yin' power

  But even then, it'll still take a long time before a balance between those two forces gets finally established

  He also noticed that her body is recovering energy on its own by sleeping, and from what he could tell it won't take long for her to wake up on her own, he could estimate that it'll take about 3-4 days max

  This is notably different from other demons who recover and evolve by eating the flesh of humans

  Furthermore, he finally found out the reason for demons 'insanity', simply put the soul is suppressed by the 'Yin' energy while instincts are being amplified

  This instinct isn't just about eating demons and evolving, that is just the most basic form it has

  It is also about obsession, which caused demons to not only be bloodthirsty but also have one thing in common and that is nearly everyone has a fixation of his own

  Daki for example only eats beautiful women, Akaza doesn't eat females and is obsessed with getting stronger, and even Muzan himself is obsessed with becoming perfect

  Such obsessions are actually normal at first, and this instincts amplification doesn't create them, it just amplifies them further and further

  That is also why when those demons finally die and their obsessions dissipate, they all restore their sanity and clarity

  Discovering this Lorien had a look of sudden realization as he fell deep in thoughts thinking of his next course of actions

  To be clear, Lorien has no interest in becoming a demon, he is only interested in the immortal factor and the awakening of a physical ability

  So if everything goes well he'll end up with Two ability seeds of 'Immortality' and 'Random Ability' which he then could improve further using his ability and 'copy paste' it so he could give it to those close to him

  This isn't because Lorien is attached to his human body and identity

  It's just that this demon blood is too low of a rank if it was a very high ranking creature he may have been very tempted to do switch races

  Some may say that humans have 'infinite' potential with powerful adaptability and evolution and all others have a limit or a weakness of sorts, but that is actually incorrect

  It was never the human blood and body that had this 'infinite potential' as they were not unique in that adaptability and evolution 'feature'

  All creatures have it, it's just more apparent in some more than others, and that is mainly because of the difference in lifespan

  It is actually 'human thought' that has that limitless potential

  Wisdom, Knowledge, and Inheritance, it's those things that are humanity's most powerful forces, It was never such thing as brute force, physic..etc

  Not to mention that human physic actually has a lot of limitations in many words, for example in Mondaiji where humans aren't able to reach 3rd digit (Almighty Domain)

  As for those humans in other words that were able to reach incredible heights, it was mostly thanks to the worlds power system

  Of course, even those physical limits possessed by other humans don't exist for Lorien who has the ability to turn dreams into reality

  So what he seeks now is to take the advantages and discard the weaknesses

  Similar to what he wants to do with the demons, take their immortality and ability and discard all the other things

  Just then, after having finally diagnosed her and got his thoughts organized, Lorien was about to release her wrist, and tell Urokodaki that he is able to heal her

  But just then, an idea appeared in his mind as he looked at the old man observing him

  'Hmm, this should make the following things much easier'

  [Reality]: Special effects

  -

  All of this actually didn't take much time, as in Urokodaki and Saigai's perspective, Lorien just sat there and held her wrist for about a minute doing nothing

  Saigai knew Lorien's ability so she knows that he is using it right now, but Urokadaki didn't know anything about it so as he watched this a frown appeared on his masked face

  It was at this moment that Lorien activated his ability

  [Reality]: Special effects

  Suddenly golden light appeared in the room shrouding both Lorien and Nezuko, this golden light gave off a calming and gentle aura

  Following that this light kept pulsating and humming as if doing some sort of task

  This lasted for five more minutes before it finally dimmed and then disappeared

  Looking at all of this the old man was shocked as he didn't know what to do, but thankfully Lorien's next words woke him up

  "I checked her state, I can indeed heal her..."
