"It's you guys, thank goodness you're here. I was worried something happened to you, after all, you're my recommendations!"
Doma seemed to heave a sigh of relief, but those who knew him well understood that he was just pretending.
"Doma-sama, there's still a Lower Moon here, so it's unlikely that they have been eliminated!"
Daki pointed to a person with characters in their eyes, as Upper Rank and Lower Rank have different eyes.
"It looks like the Lower Ranks have also arrived, so it does seem like there are no vacancies. However, that makes sense, as there hasn't been a gap in ranks for a hundred years. Naturally, it's not easy for a gap to appear directly!"
Doma was well aware that the longer a demon remained in the Upper Ranks, the stronger they became.
It's because of that, that if they couldn't eliminate an Upper Moon demon within a short period, it would become very troublesome later on. To take down an Upper Moon, the Demon Slayer Corps would even need to mobilize multiple Hashira.
Soon, other Upper and Lower Ranks were gradually transported to the location, a total of twelve of them. However, the difference in strength between the Upper and Lower Ranks was significant, with a single Upper Rank easily capable of eliminating all the Lower Ranks. For someone like Muzan, he only cares about the Upper Ranks.
As for the Lower Ranks, they were essentially the reserve forces for the Upper Ranks, nothing more. Even if they were killed, Muzan wouldn't even bat an eye.
Moreover, the Lower Ranks seemed more like a means to provide experience to the Hashira. The prerequisite for becoming a Hashira in the Demon Slayer Corps was to either defeat a Lower Moon or eliminate a large number of demons. However, in general, no Hashira could reach fifty demon kills without encountering a Lower Rank.
So, the Lower Ranks served as a source of experience for the Hashira.
Both Upper Ranks and Lower Ranks had gathered together, and naturally, Muzan, who is the big boss, had come out as well.
"Muzan-sama, what is the purpose of summoning all of us this time?"
Upper Ranks held high status, so Doma was quite relaxed in conversing with Muzan. This, however, left the Lower Ranks feeling anxious as they observed that Doma, the Upper Rank Two, could speak with Muzan so casually and even directly mentioned his name.
"I won't beat around the bush, it's about the Demon Slayer Corps. They've been missing for over two months now, and there's no trace of them either. So, I've called you all here this time to find the Demon Slayer Corps. If we can't find them, I won't be at ease!"
After several changes in his expression, Muzan stated his purpose, seemingly unconcerned about Doma's behavior. He was indeed quite indulgent with the Upper Ranks. Moreover, right now, his focus was on the Demon Slayer Corps, not elsewhere.
"It's indeed true that the Demon Slayer Corps has been missing for a while. However, during this extended period, have none of the other demons been able to find any trace of them?"
Doma found it quite strange, and so did the other Upper Ranks. It was understandable that they couldn't locate the Demon Slayer Corps headquarters, but the complete absence of any information about them was perplexing.
"Even the Mount Fujikasane is nowhere to be found, and the positions of some of the trainers we located before have also disappeared. Even the information we had about the swordsmith village is now completely gone."
This was what frustrated Muzan the most, the total lack of information. If he had any other options, he wouldn't have summoned the Upper Ranks.
"It seems to be really troublesome!"
After some discussion, the group of demons left. Their current task is to locate the whereabouts of the Demon Slayer Corps.
However, there are only a dozen of them, so their search efforts were limited. Of course, they are not stupid. They had gathered a significant number of demons under their command and released them to assist in the search.
As for Demon Slayer Corps, after more than two months of hellish training, each member had their combat abilities increased by at least two-fold.
Among them, Gyomei and Tanjirou, along with his sister Nezuko, are the most powerful. They had not only awakened their Demon Slayer Marks but also mastered the Transparent World.
Tanjiro also managed to connect the forms of the Sun Breathing by relying on his exceptional physical attributes.
The protagonist is indeed the protagonist, the current Tanjiro, although he couldn't yet reach the level of Yoriichi in terms of mastering the forms, in terms of raw physical combat abilities, he had surpassed the level Yoriichi had reached.
The only difference was in some aspects of mastery, which is why it's said that the main character's halo is very overpowered, and Nezuko is no different.
Her strength had also increased rapidly, and with some guidance from Asahi, Nezuko had embarked on the path of a Magic Swordsman. She not only mastered the Sun Breathing but also learned her original Blood Demon Art. When she got into action, she was just like a Magic Swordsman.
Her sword was now adorned with crimson flames, and her combat power was incredibly high.
As for the others, their combat effectiveness has also reached the level of the Hashira, and they are much stronger than during the final battle.
It can be said that their basic combat effectiveness has been raised to a very terrifying level, all in just two months.
Moreover, their weapons have also been enhanced by Asahi, and its power increased significantly.
After completing the training, Asahi naturally let them go out enjoy themselves, with the goal of giving Muzan a surprise.
As for whether Muzan would continue to hide and refrain from taking action, that wasn't a significant concern. Later on, Asahi would naturally go and confront him.
The location of the Infinity Castle might be a big issue for others, but for Asahi, it was no problem at all. It was nothing more than a unique city built underground.
Asahi probed the gathering points of the surrounding demons, and then handed over the information to the Demon Slayer Corps.
The members of the Demon Slayer Corps had been in continuous training for over two months, so this time, they couldn't contain themselves any longer.
This group of people needed to vent, and demons were their target.
"Interesting. You two, I remember that you wanted to seek revenge against a particular demon, right?"
Asahi suddenly sensed a presence much larger than the other demons, which is none other than Doma.
"Revenge! Do you know who is the demon that killed my sister?"
Shinobu's expression instantly turned into one of intense anger. She had been harboring this anger because she despised demons.
Her sister, Kocho Kanae, was indeed a unique individual. She hopes that demons and humans could coexist despite having been attacked by demons. Her thoughts were quite peculiar, and she is indeed a very strange person.
But Shinobu had changed after her sister was killed. Now that she had found her enemy, she couldn't possibly hold back.
As for Kanao, she had also been taken care of by Asahi. She had some mental issues due to a tragic childhood experience that had nearly shattered her nerves.
Afterward, although she lived together with the others, she couldn't fully integrate as she had too many concerns.
But for Asahi, it was very simple. He just had to heal her with an illusion.
It was a convenient solution that didn't require much effort. So, the current Kanao had already returned to her normal state.
Knowing that the demon who killed Kanae was here, the anger of the two women couldn't be contained any longer.
