A day later, everyone arrived at a relatively remote small mountain village.
The two Demon Slayer Corps members guarding here saw that all the Pillars had arrived and immediately reported the information.
It turned out that while they were tracking a demon, they found that the demon was suddenly teleported into a very prosperous city.
It was as if a portal had been opened; after the demon entered, the prosperous city disappeared.
After hearing the report, everyone went to the place where the Infinity Castle had appeared.
But there was nothing, no suspicious areas.
Helplessly, everyone could only turn their gaze towards Lin Che.
Lin Che smiled and said, "Under Kibutsuji Muzan's command is a female demon named Maime. Her Blood Demon Art is to control the Infinity Castle, she can teleport anyone to the Infinity Castle and can open the entrance to the Infinity Castle anywhere."
Shinobu Kocho also said, "This kind of space-type ability is too troublesome, can you track it?".
Lin Che smiled and nodded, "It's nothing, since a passage to the Infinity Castle was opened here, there will definitely be traces left in space."
As he spoke, he took out Skyward Pride.
It was also the first time everyone had seen Lin Che's weapon; they didn't expect it to be such a magnificent greatsword.
Lin Che raised his sword and chanted the divine words, "By this oath, I do not allow anything I cannot cut to exist!"
Although he had obtained the demon characteristic, he could cast magic and spells without chanting.
But authority is different from magic and spells; it is a cosmic rule, an ability belonging to deities!
Lin Che didn't chant all the divine words, only one sentence.
The next moment, his arm turned into silver metal.
His entire body burst out with cherry-red Demon Power, gathering on the sword.
Seeing this, everyone was extremely curious.
This was the first time they had seen Lin Che use his abilities, and it was incredibly powerful and handsome.
With one sword slash, a huge opening was cut in space.
And on the other side of space, was the Infinity Castle!
The Pillars of the Demon Slayer Corps saw the Infinity Castle and all became excited.
Among them, the most excited was Yoriichi Tsugikuni.
Last time, because he didn't kill Kibutsuji Muzan, he was expelled by the people of the Demon Slayer Corps. This time, he was determined to kill Kibutsuji Muzan.
Lin Che said to everyone, "Let's go in!"
After speaking, he was the first to enter the Infinity Castle.
Seeing this, the Pillars of the Demon Slayer Corps followed closely behind.
After everyone entered, the spatial cut healed again.
Lin Che didn't care and directly released the Great Forbidden Spell, ""Unlimited Blade Works"", pulling the entire Infinity Castle into it.
He never liked fighting on enemy territory, so it was much more enjoyable to fight on home turf.
This way, no matter how Maime controlled the Infinity Castle, she couldn't escape.
After the Infinity Castle was pulled into ""Unlimited Blade Works"", Kibutsuji Muzan immediately sensed something was wrong.
When he saw Lin Che and the others, he was completely terrified.
Because he saw a figure that filled him with dread.
"It...it's you, Yoriichi Tsugikuni!" Kibutsuji Muzan said with a trembling voice.
"Muzan, we meet again. This time, I won't let you escape!" Yoriichi Tsugikuni said with an unchanging expression.
His entire body exuded a powerful aura that made it difficult for Kibutsuji Muzan to breathe.
At this moment, Upper Rank One, Kokushibo, also walked out of a room in the Infinity Castle.
When he saw Yoriichi Tsugikuni, his ugly six eyes were also filled with shock.
"How is this possible... I remember you were dead, I personally cut your corpse in half, why are you still alive? Why are you so young?" Kokushibo roared angrily, questioning Yoriichi Tsugikuni.
However, the current Yoriichi Tsugikuni was brought back by Lin Che from the past; the time period he was in was just after he was expelled by the Demon Slayer Corps.
So he was not aware of the subsequent events.
But this did not prevent Yoriichi Tsugikuni from thinking of parallel dimensions.
Established history cannot be changed, so if Lin Che traveled to the past and brought him to this era, then the history of his era and the history of this era are already different.
This is like a timeline that suddenly splits, becoming two different parallel dimensions.
"How could I die without killing you!" Yoriichi Tsugikuni still said expressionlessly.
"Since that's the case, then let's settle this once and for all!" Kokushibo drew his sword.
However, at this moment, the Water Pillar, Flame Pillar, Sound Pillar, Mist Pillar, Serpent Pillar, Wind Pillar, and Stone Pillar stood in front of Kokushibo.
"The traitor of the Demon Slayer Corps will be killed by us!" The seven said in unison.
"Oh my, oh my, Lord Kokushibo, you certainly have many enemies," Upper Rank Two, Doma, said, appearing beside Kibutsuji Muzan.
At this moment, he showed no fear or tension at all, and was even gnawing on a young girl's thigh.
His mouth was full of blood and flesh, which was disgusting to see.
At this moment, Flower Pillar, Kocho Kanae, stepped forward and asked, "Doma, do you still remember me?"
Doma looked at Kocho Kanae, suddenly frowned, and said, "It's you, I remember you were dead!"
"Heaven had mercy and allowed me to be resurrected again to seek revenge from you!" Kocho Kanae said as she drew her Nichirin Blade.
At the same time, Insect Pillar Shinobu Kocho, Love Pillar Mitsuri Kanroji, Kanao Tsuyuri, and Nezuko also came to Kocho Kanae's side, planning to deal with Upper Rank Two, Doma, with her.
When Kibutsuji Muzan heard Kocho Kanae's words, he suddenly thought of something and asked with a shocked expression, "Do you have a way to resurrect the dead?"
Everyone exchanged smiles and did not answer.
Before Kibutsuji Muzan could continue speaking, the battle fully erupted.
Yoriichi Tsugikuni vs. Kibutsuji Muzan!
The male Pillars together against Kokushibo.
All the females together against Doma.
Then Tanjiro and Genya Shinazugawa teamed up to deal with Maime.
Inosuke and Zenitsu teamed up to deal with Kaigaku.
As for Lin Che, he was watching from the side; this level of battle did not require him to act.
Since they all had their own grudges, he would let them resolve it themselves.
If he were to act, it would be an instant kill.
However, Lin Che wasn't watching alone; he also started a livestream for the people in the Chat Group to watch together.
The battle was not as tragic as in the original work; it was almost a one-sided crushing.
Yoriichi Tsugikuni, relying on his self-created Breath of Fighting, instantly killed Kibutsuji Muzan, completely shattering his body.
Although Kokushibo was powerful, the current Pillars of the Demon Slayer Corps, under Lin Che's training, each had fighting power no less than his.
The seven of them teamed up, quickly crushed him, and then killed him.
Doma was the same; he who liked to eat women ultimately died at the hands of a group of women, his body chopped into pieces.
Finally, Maime and Kaigaku were also killed by Tanjiro and the others.
At this point, all the demons were eliminated.
To prevent Kibutsuji Muzan from resurrecting, Lin Che finally used the authority "Sun Sovereignty" to summon a sun.
He evaporated the entire Infinity Castle and the corpses of Kibutsuji Muzan and the others.
After leaving the Infinity Castle, Lin Che received a notification from the Chat Group that the mission was completed.
Having dealt with all the demons, the people of the Demon Slayer Corps were overjoyed.
They planned to hold a banquet for three consecutive days to thoroughly celebrate.
But Lin Che didn't have enough time; after the mission was completed, he only had 12 hours of remaining time.
So, after the celebration that night, Lin Che gathered all the highest-ranking members of the Demon Slayer Corps.
Besides Kagaya Ubuyashiki and his wife Amane Ubuyashiki, there were all the Pillars, as well as Tanjiro and the other protagonists.
When Lin Che saw that everyone was present, he nodded to Shinobu Kocho.
Immediately, Shinobu Kocho began to speak.
The content of her speech was simple: Lin Che was from another world, a dependent of a deity.
His purpose in coming to help the Demon Slayer Corps this time was to recruit them, so they could also go to Orario and become dependents of a deity.
When everyone heard Shinobu Kocho's words, they were all shocked.
Although they had known that Lin Che was from another world, they did not expect his purpose to be to recruit the Demon Slayer Corps.
Instantly, everyone's gaze turned towards Kagaya Ubuyashiki.
Kagaya Ubuyashiki, with a smile on his face, said, "Kibutsuji Muzan is dead, there are no more demons in this world, and the Demon Slayer Corps no longer needs to exist. If you want to venture into another world, I support it."
Hearing Kagaya Ubuyashiki's words, everyone's eyes lit up.
Another world, they all longed for it.
And after witnessing Lin Che's powerful strength, they also wanted to become as strong as him.
Sound Pillar Tengen Uzui suddenly asked, "If we go to another world, can we bring our families?"
He had three wives, he couldn't just abandon them in this world and go adventure in another world alone.
"Of course you can!" Lin Che nodded.
Tengen Uzui's three wives were also very capable ninjas; if they joined a Familia, they should also be able to grow into high-level adventurers.
Everyone smiled when they heard Lin Che's answer.
Before leaving, Lin Che took Tanjiro and Nezuko to his old home.
Then he dug up the graves of their parents and younger siblings and resurrected all of them.
The family had experienced life and death separation, and their reunion was a heartwarming scene.
Originally, Tanjiro planned to bring his family to Orario, but his parents both shook their heads and refused.
They still plan to live in this world. Anyway, the demons have been eliminated, and this world is no longer dangerous.
