The head of Muzan Kibutsuji in his right hand had completely turned to ashes, and at the same time, the Infinite City around him began to collapse, revealing the original streets.
When Muzan Kibutsuji died, far away, the Nakime was also dealt with at the same time.
Although the Nakime could control the entire Infinite City, she could not withstand the joint attack of two Hashira and quickly fell.
With Nakime lost, Muzan Kibutsuji also died on the spot, and the outcome of the Infinite City was predictable.
The surrounding space began to twist and change, and the interior of the Infinite City began to collapse.
At the same time, the war within the Infinite City was also coming to an end with Muzan Kibutsuji's death.
The battles of Upper Moons Two, Four, and Six with the Hashira also ended at this moment.
Kagaya Ubuyashiki coughed a few times, watching the gradually dissipating Infinite City, tears streaming down his face. Kagaya Ubuyashiki was an extremely strong person, but even so, in such a situation, he could not contain his excited emotions.
Kagaya Ubuyashiki murmured, "Is it finally over? I can feel it; Muzan Kibutsuji's aura has disappeared. This intersection that has lasted for over a hundred years has finally come to an end."
His wife reached out to comfort him, and Kagaya Ubuyashiki smiled at her, saying, "Today is a good day."
The two looked into each other's eyes, tears welling up.
Roa was not idle either, walking towards the collapsing interior of the Infinite City.
Muzan Kibutsuji granted blood to the demons; he was the beginning of everything and the end of everything. The moment Muzan Kibutsuji died, the fate of demons around the world was already sealed.
In countries where life was relatively good, regardless of where the demons were hiding, they were all in pain and howling, their bodies continuously expanding.
When the Demon King died, those who had become demons relying on Muzan Kibutsuji's blood had only one outcome—death.
A demon that was about to grab a human to devour suddenly felt something was wrong with its body. Its limbs began to swell, blood surged, and its bones were pushed outward.
The demon was a bit confused, and before it could say anything, it suddenly felt a force breaking through the restraints within its body, followed by a loud bang.
It exploded.
The trembling man beside it was momentarily stunned.
Then, looking at the surrounding corpses, tears flowed uncontrollably.
The man's name was Suanle, a passerby. Like most ordinary people, he was eighteen years old and unmarried. In this era, being unmarried at this age indicated that finding a wife was becoming problematic.
First of all, there was no need to mention the appearance of the passerby; it was naturally at the level of a passerby.
Secondly, there was no need to mention the luck of the passerby; being taken to this place by a demon was certainly not good luck.
As usual, the passerby walked along a country path, feeling very troubled. One was worry about the future, and the other was worry about not being able to find a wife.
In this world, not many people knew about demons, but certainly not too few. Under the government's deliberate cover-up, many ordinary citizens were unaware of the existence of demons.
The passerby had no wife and was filled with anxiety about the future, feeling that his life was full of hardships, so he decided to take a walk under the moonlight to clear his mind.
As luck would have it, he ran into a demon.
Even the demon was momentarily stunned when it saw the passerby, remaining silent for three seconds. The passerby panicked and ran away, and the outcome was predictable—he was caught, then taken back to the lair, ready to be steamed and eaten.
The passerby was so scared that he urinated himself. This place was located deep in the mountains, and in fact, demons' lairs were mostly in the mountains.
In a dilapidated temple in the deep mountains, a foul stench of blood permeated the air, surrounded by bones left behind by the demons, and even a few human skulls were placed on the ground.
The moment he saw the skulls, the passerby shivered again.
Just when the passerby thought his life was in danger, the demons put on a fireworks show for him.
Explosions echoed from all over the world.
With the task completed, there was no need to linger in this world any longer.
All the benefits that needed to be obtained had been acquired. Not to mention the Transparent World, just the breathing technique was enough to consider it a return on investment, not to mention he had also devoured Muzan Kibutsuji's blood. Although the help he received seemed minimal.
This journey through worlds had caused a significant change in the timeline due to Roa's appearance.
What was originally planned to be a month-long journey now seemed to be expedited.
Had only a few days passed? The time-space power spent earlier felt wasted. He initially thought it would take a long time to resolve a world's side quest, but it seemed that was not the case.
How long had it been since returning to the world of "Mushoku Tensei"? It was likely that less than ten days had passed.
Anyway, Eris had already been entrusted to Rudeus. After returning, he would see if he could summon Mitsuri Kanroji, and then he would go meet Roxy.
It had been a long time since he last saw Roxy, and Roa missed her very much. Roxy had mentioned her location in a letter, as she had single-handedly broken through a high-difficulty dungeon near the Shirone Kingdom and was hired as the court magician of the Shirone Kingdom and the teacher of the seventh prince. As for the court magician position, Roxy agreed, but she felt hesitant about becoming someone else's teacher. Recently, she even wrote a letter half-jokingly, half-complaining.
The gist was that after teaching Roa, she didn't want to teach anyone else, fearing she might encounter another prodigy like Roa.
The seventh prince was not a good person, and Roa agreed with that. However, losing a part-time job would make the prince's salary very low. Roa felt he needed to help Roxy, to make his feelings clear, so she wouldn't be taken away by someone else.
Thinking of this, Roa felt a bit troubled.
How should he deal with Mitsuri Kanroji? One big wife and one small wife—where would he hide them? Should he let them meet?
He felt that letting them meet would lead to a very embarrassing situation for him.
The psychological issues from his previous life were acting up, creating a scene reminiscent of a Shura field.
Roa constantly reassured himself that the ethical values of the two worlds were vastly different, trying to convince himself.
The effect was outstanding; regardless of whether others believed it, Roa certainly did.
Suddenly, Roa realized something was off. Why was he worrying so much?
Once he arranged for Mitsuri Kanroji, he could spend the remaining time opening another world.
The King-level Sword God Style was still too much for dealing with the Dragon God. Even though he now possessed nearly limitless magical power, if it came to close combat with the Dragon God, he would likely be the one in trouble.
Unless he could activate Moment, using Moment's word spirit combined with the speed of the Sword of Light to instantly take down the Dragon God.
But then again, the two were actually on the same side.
It was just that trying to recruit the Dragon God as his subordinate by demonstrating his strength was impossible.
However, the next world had to be one where he could obtain a suitable weapon.
Roa kept thinking, eventually sighing. The future could be dealt with later.
For now, it was best to focus on the present.
Roa touched his somewhat tattered clothing. Although his originally splendid attire had long since become tattered in battle, his dazzling golden hair remained completely unharmed.
The brilliant golden hair still flowed down to his waist, swaying gently in the summer breeze.
Although Roa usually didn't say much, he actually paid great attention to his hair, even during battles, he took extra care of his shining golden locks.
Roa took a deep breath and walked towards the end of the road. Although this world still had heaven and hell, he was not interested in those.
The exposed streets began to appear one by one, and the surrounding alleys quickly came into view. Since the battle occurred within the Infinite City, the outside alleys were completely undamaged.
Well, except for the place where Roa fought Muzan Kibutsuji.
Roa raised his gaze, looking at the moon in the distance. The moonlight was still so bright, casting its pure light on the ground and on Roa, making him feel refreshed.
Roa leaned against a handrail and murmured, "Has the evil in the world completely disappeared?"
Due to the distance of the teleportation, even Roa did not know where he currently was. He looked around and walked along the street, activating the Transparent World, using magic as assistance to sense his surroundings.
It was fine until he sensed it; as soon as he did, Roa couldn't help but frown.
Surrounding him were not only members of the Demon Slayer Corps but also a large group of other people.
Roa thought for a moment and decided not to meet up with the Demon Slayer Corps members first, but to check out what was going on with that group of people.
With Roa's strength, it was extremely easy for him to sneak around to their back. He poked his head out to see where they were, and just one glance made him click his tongue.
This was a Japanese military unit, about thirty people, all armed with guns, and some even brought mortars.
The leader was a middle-aged man dressed as a priest. Without asking, Roa could already roughly guess the outcome.
Current Japan was not peaceful. The free Americans had blasted open the doors of a country that was living relatively well, and capitalist ideas flowed into Japan along the coast.
Gunpowder, knowledge, ideology, literature, and various political matters had a strong impact on Japan.
Although life seemed peaceful at the moment, the seeds of capitalism had long been developing. The current era was already the new century, and the appearance of demons brought not only disadvantages to the Demon Slayer Corps.
For instance, if all the demons were to disappear, the first to be eliminated by the government would be the swordsmen of the Demon Slayer Corps.
Swordsmen were still too unstable, especially the organization of the Demon Slayer Corps. When the government needed them, they were the Demon Slayer Corps, but when the government no longer needed them, the Demon Slayer Corps lost its value.
After realizing all this, Roa could somewhat guess the intentions of the group.
They were most likely here to "kill the donkey after the grind."
Roa thought for a moment, took a few steps forward, and pretended to be weak, using a knife to cut his own skin, trying to appear as disheveled as possible.
But as soon as the knife grazed his skin, blood had not even begun to flow before it had already healed.
Roa raised an eyebrow, not giving up. He cut himself again, but unfortunately, the blood only flowed a little before healing again.
Roa understood what regeneration meant.
After a moment of silence, Roa tidied himself up a bit, tore a few holes in his clothes, and rushed towards the priest's location, looking extremely disheveled.
Stumbling and with tattered clothing, he looked just like a young swordsman who had just experienced a fierce battle and was injured.
Perfectly fitting the character!
Seeing the somewhat disheveled appearance of Roa, the priest instinctively frowned. He coldly reprimanded, "Stop! Demon Slayer swordsman? What's going on?"
He then waved his hand towards the thirty soldiers behind him, and in an instant, all thirty soldiers raised their dark guns in unison.
Roa lowered his head and did not look at the other party. With his current looks, he was quite recognizable.
Although Roa did not look at him, the priest frowned slightly, as if recalling something, and suddenly asked, "Are you the Hashira Roa?"
While Roa was still pondering how to respond, the priest had already revealed his identity, which made Roa feel a bit awkward.
Roa lightly coughed a few times and nodded. The priest's eyes brightened, and he patted Roa on the shoulder, asking, "Has Muzan Kibutsuji been killed? Since you are here, Muzan must be dead."
Roa thought for a moment and nodded, saying to the priest, "Muzan Kibutsuji is dead; I killed him. However, I am also severely injured and need help. Please take me to the hospital."
The priest's smile grew even brighter, his entire face radiating a gentle expression. But the moment Roa saw that smile, he felt that the other party was not friendly.
Roa was still in a state of heightened awareness, particularly sensitive to the goodwill and malice of others.
He could sense that the priest was exuding a strong malice at that moment.
The priest slowly spoke, unhurriedly, "No need to rush. I will send you on your way."
Just as the priest's hand was about to come down, a sword was already pressed against his throat.
Roa looked up, revealing his exceptionally handsome face.
Roa curiously examined the priest and asked, "Hmm, do you really want to kill me?"
The priest, taken aback by the sword at his throat, then his expression darkened. He coldly said, "Roa, do you want to see what you are doing? I kindly offered to send you on your way, and you actually put a knife to my neck. Truly, people like you, who have power but do not understand respect, should not exist in this world. You are more terrifying than demons."
Roa was momentarily stunned by the priest's words and didn't know how to respond.
Should I say that the Japanese are indeed the Japanese?
Their shamelessness is off the charts; they can even bite back like this.
Seeing that Roa did not speak, the priest became even more arrogant. He said, "Kid, if you don't let me go, do you want to drag the entire Demon Slayer Corps down with you for your mistake?"
Roa wasted no time, directly reached out, and expressionlessly broke the priest's arm. The priest let out a wail, the pain from his dislocated arm surged to his head, and his face instantly turned extremely grim, his mouth twitching in pain.
Roa patted the priest's cheek and curiously asked, "Do you think I'm a fool? The malice radiating from you is obvious. Oh, by the way, I'm not as easy to talk to as those people."
The priest's face showed humiliation, and he glared at Roa with a sinister look. Roa felt somewhat speechless at this point.
The knife pressed against the priest's neck tightened a bit more.
Roa could sense the priest's stubborn attitude, so he simply said, "Do you think I dare to kill you?"
The priest was about to retort with some harsh words, but when he looked up, he felt Roa's cold golden eyes.
The Nichirin Sword cut through the skin of his throat, and the heat from the sword spread.
The priest swallowed hard, stopped talking, and waved his hand to the crowd, saying, "Put down your weapons and let the Hashira go."
Roa did not waste any more words, directly taking the priest hostage and moving towards the group of Demon Slayers.
Thus, one person and an army were mutually holding each other hostage.
Roa expressionlessly found the bewildered priest's daughter and asked, "Do you know what's going on?"
The priest's daughter, was taken aback when she saw her father with a knife at his throat. Then she looked at the soldiers behind him, as if realizing something, and her expression turned extremely grim.
She knew her father's character all too well, and she looked at her father with a cold expression.
At that moment, the priest's eyes lit up when he saw her daughter. He hurriedly said, "It's me, your father! Look at what this brat has done! He actually put a knife to my neck! I'm a government official! Isn't this forcing you to go against the government? Come on, let me go, and we can let this matter go. If it escalates, neither of us will have a good ending."
The priest's daughter remained silent, only coldly looking at the soldiers behind Roa, sneering, "So well-armed? It seems you were prepared for this."
The priest feigned confusion, hurriedly waving his hands, saying to her, "Daughter, what are you talking about? Shouldn't you be firmly standing behind me at this time? I am your father!"
The priest's daughter also reacted, showing a bitter smile. He deeply bowed to Roa and said, "I'm sorry, I did something foolish. I thought that by telling the priest, he could help us. Even if we couldn't eliminate Muzan in the end, we wouldn't end up in such a dire situation. I'm sorry."
At that moment, the Hashira also walked out from the Infinity Castle.
The first to step forward was Tanjiro Kamado, who was slightly stunned by the large scene. He looked at Roa, who was threatening with a knife, and then at the dense array of gun barrels behind him, swallowing hard.
