He arrived beside Nezuko and first checked her condition.
Nezuko was not injured, but she had been injected with Muzan's blood, which meant she was transforming into a Demon.
The only thing unclear was how much blood Nezuko had been injected with this time, and whether she would be able to control her desire for flesh and blood, like in the original story, and become a special Demon.
At this moment, due to the injection of Demon blood, Nezuko's body began an irreversible transformation into a Demon, and amidst the drastic physical changes, her brain entered a protective comatose state.
However, after such a drastic change, it would be difficult for Nezuko to retain her humanity, and Luo Men also didn't know if he could control Nezuko on his own; he was not like Tanjirou, who had a blood connection and more than ten years of familial affection with Nezuko.
Although Luo Men felt that Nezuko's gaze towards him was a bit off, Luo Men felt that Nezuko might have feelings for him; after all, among the men Nezuko had come into contact with, Luo Men could be said to be the most outstanding one, aside from her brothers. And for twelve or thirteen-year-olds to consider marriage was actually the nature of this country.
However, Luo Men was unsure how strong this feeling truly was.
After some thought, Luo Men believed that he still needed to find Tanjirou first. Tanjirou, as a passionate, righteous, and gentle protagonist, had an unparalleled ability to emotionally sway others through his words.
Just as he was thinking about Tanjirou, Tanjirou's voice suddenly came.
"Luo Men, what happened?"
In the darkness, Tanjirou, relying on his keen sense of smell, accurately arrived beside Luo Men.
"Nezuko, Nezuko, what happened to you?"
However, upon arriving beside Luo Men and seeing Nezuko in Luo Men's arms, feeling the increasingly cold aura emanating from Nezuko, Tanjirou looked at Luo Men with a hint of expectation.
"Luo Men, what exactly happened to my sister, Nezuko?"
In the darkness, Tanjirou's eyes could be vaguely seen, revealing genuine emotion.
"The Demon King Muzan just appeared; she might be turning into a Demon."
"How could this be?"
Seeing Tanjirou stunned, Luo Men didn't know how to comfort him, but a strong person like Tanjirou probably didn't need his comfort.
The current situation might still be a bit too much for Tanjirou; the monster that only existed in legends, when it truly appeared, that feeling was incredibly worldview-shattering.
"What should I do then?"
Looking at Luo Men, Tanjirou looked at him with a hint of pleading, wanting to know the solution from Luo Men.
"There is no solution at present. If there were, Demons would not still be causing trouble, and the Demon Slayer Corps would not have continued to this day."
At this moment, snowflakes also began to fall from the sky, as if responding to Luo Men's words.
"No matter what, I will save Nezuko. Nezuko will definitely return to being human." A moment later, Tanjirou suddenly looked up, staring at Luo Men, and bowed seriously, saying, "So, please don't kill Nezuko."
Tanjirou knew that Luo Men was a Demon Slayer, so if Nezuko really turned into a Demon, Luo Men might genuinely slay Nezuko. Therefore, he directly made his request.
Seeing Tanjirou like this, Luo Men was not surprised; Tanjirou was just such a person, a person who valued his family.
However, if Tanjirou were not the protagonist, or rather, if it weren't for the fact that Tanjirou and Nezuko seemingly both ate the Blue Spider Lily in their childhood, Luo Men wouldn't have believed that Nezuko would be that special Demon.
"Uh ah~"
At this moment, Nezuko's body also completed its final transformation, finally letting out an unintelligible roar.
Watching Nezuko's fingernails rapidly grow and sharpen, Luo Men also looked at Tanjirou.
Helping Nezuko up, Luo Men also controlled Nezuko's hands behind her back. As a newly born Demon, Nezuko's strength was limited, and Luo Men could easily control her.
The awakened Nezuko also began to roar, staring at Tanjirou in front of her, and wanted to lunge at Tanjirou with her mouth open, but she couldn't do it with Luo Men restraining her.
Amidst her struggles, Nezuko's body also began to grow, then transformed into an adult girl, and at the same time, the force of her resistance continuously increased.
"Nezuko, come on, Nezuko, you must endure! You absolutely cannot turn into a Demon!"
Looking at Nezuko, Tanjirou showed no fear, grabbing Nezuko's shoulders and shouting.
Watching Tanjirou, who was calling out to Nezuko with tears welling up in his eyes, the abundant emotional power was indeed very strong.
Tanjirou did not stop shouting but continuously tried to call out to Nezuko.
As for whether it had any effect, Luo Men, who was controlling Nezuko, could clearly feel Nezuko's resistance lessening.
Suddenly, Luo Men saw crystal clear tears falling down the girl's cheek.
Although Nezuko had just turned into a Demon and couldn't quite control her instincts, with Tanjirou's shouts, Nezuko's latent will was successfully awakened by Tanjirou.
Amidst Tanjirou's continuous shouts, Nezuko finally became somewhat lucid, and then her body shrunk again.
However, for some unknown reason, her will could be awakened, but her memories were not, leaving her in a pure state, like a blank slate.
"However, Muzan's aura seems to be rapidly fading."
Feeling Nezuko's state, Luo Men also thought this, vaguely guessing Nezuko's condition. It should be due to her own unique qualities, beginning a transformation similar to Tamayo, breaking free from Muzan's control.
One must know that all Demons, except in special circumstances, cannot break free from Muzan's control.
"I wonder if I can guide Nezuko's memories through Telepathy to help her recover."
Luo Men thought for a moment, looking at Nezuko, who had shrunk again and showed no violent tendencies. He also released Nezuko's hand, but for safety, Luo Men still found a bamboo muzzle and put it on Nezuko, just in case.
Hugging the shrunken Nezuko, Tanjirou's tears flowed uncontrollably as he said, "Nezuko, you will definitely return to being human. I will definitely find a way to turn you back into a human."
Watching the siblings embracing, Luo Men also reflected on himself.
Although he had slain many Demons and honed his skills well in the past six months, in terms of his fundamental personality, he seemed to have not yet shed the bad habits of his previous life.
He used to dislike characters who were decisive in the beginning but then hesitated later, leading to subsequent troubles. He never thought he would become such a person.
This time, he should either go all out to try and kill Muzan, or directly resolve the Kamado Family's crisis through other means.
Most importantly, hesitation and indecision during battle, as well as excessive overthinking, led to Nezuko being affected later.
Even if he went all out and forced Muzan to flee and hide, if he wanted to deal with Muzan later, it wouldn't be impossible to lure him out through other methods.
Furthermore, even if Muzan disappeared and kept hiding from him, what then? If he died, then what did Muzan matter? He didn't have that much sense of mission.
If his strength was so great that he became immortal, wouldn't finding and dealing with Muzan be a simple matter then?
No matter what, correcting mistakes when one realizes them is the true path.
Closing his eyes, Luo Men recalled that Tamayo would be able to research a human-transformation medicine in the future.
Therefore, his next goal was clear: defeat the Twelve Demon Moons, and then develop the human-transformation medicine first.
