The librarian, who was the champion of the World Swordsmanship Championship, traveled to the world of Demon Slayer during the Warring States Period, awakened the Great Swordsman System, and became a disciple of the Jigoku brothers.

From then on, he created various legends of his own in this world!

Muzan Kibutsuji: Facing Yoriichi, I can still escape, facing the librarian, I have no choice but to die! Yoriichi Tsugikuni: Your strength has surpassed mine! Demon Slayer Corps: The librarian is the most powerful man!

Travel through Demon Slayer and merge with Muzan Kibutsuji!

Reorganize the Twelve Demon Moons, run rampant in Tokyo Prefecture, and terrorize Japan!

End the Demon Slayer Corps, liquidate Ubuyashiki, and aim at Taisho Tenkō!

Strategy of thousands of ghosts, swallowing the world, only I am Yue Yan!

Lin Guang travels through the world of Demon Slayer and awakens the Super Treasure Chest System! In Demon Slayer, slaying demons unlocks treasure chests; defeating the navy and celestial dragons unlocks treasure chests; and defeating enemies unlocks treasure chests in Naruto. Thus, Lin Guang continues to unlock treasure chests, conquering the world!

After traveling through Demon Slayer eighteen years ago, Kamishiro Mitsuteru thought this was just an ordinary ancient world.

Until the night of the blood moon, the evil spirits tore his warm home apart.

When you are on the verge of death, the sign-in system is activated!

[Congratulations to the host for receiving the Newbie Gift Pack: Nature-type Sparkling Fruit! ]

The body instinctively transforms into elements to avoid the fatal blow!

He raised his hand and pointed, and the holy light penetrated the evil ghost, evaporating it instantly!

The loud noise attracted the dying Kanae Butterfly, and the Second Upper Moon, Douma, who was standing in front of her.

Under Kanae's desperate gaze, Kamishiro Kouki transformed into a beam of light and kicked Douma half of his body away at the speed of light. He sneered and said, "Sorry to bother you. But you can die now."

If a time traveler wants to gain strength quickly, what's the best way? Rhodes thinks the easiest thing is to take refuge in the arms of the Burning Legion's CEO.

Lord Sargeras has always been very generous to those who voluntarily surrender, and does not hesitate to grant powerful evil powers.

Rhodes began to deceive the entire Burning Legion and Sargeras to work for him to conquer the world.

One Piece World: Rhodes "Drink, Kaido, this is your fate, the fate of all you pirates."

World of Naruto: Rhodes "The Legion is invincible, the sacred tree is ours, everything belongs to the Legion."

Monster World: Rhodes "The legion is unstoppable, use evil energy to transform these titan beasts."

Devil May Cry World: Rhodes "Slave the demons, Spartan Twins, you must fight for the Legion."

Bayonetta World: Rhodes "Beauty! Are you interested in joining the Burning Legion? The Legion offers generous benefits and benefits."

When you have enough strength, hum! How can a real man live under others for a long time?

In the Marvel world, Mr. Sha is tricked into grabbing the infinite stones.

Mr. Sa encountered a group of... Mr. Sa's pawns.

Rest in peace, Mr. Sa, I will inherit everything from you, and I will inherit the great cause of the legion.

Tianji transmigrated to the world of Bleach. Knowing Bleach well, he originally thought he could make a name for himself, but fate played a joke on him. Tianji transmigrated to 1,500 years before the main storyline. At this time, there was no Shinigami Academy, and even the Gotei 13 had not yet been formed. The only one protecting the Soul King was the Zero Division, which only had two members.

That's not all. I thought I could finally enjoy life after defeating the Grim Reaper, but then I was transported to another world.

Dongfang Hao transmigrates to the world of Jujutsu Returns to War, awakening the Mangekyou Sharingan at the start, which contains multiple eye techniques: Amaterasu, Kagutsuchi, Kamui, and Tsukuyomi.

His arrival brought an unprecedented boom to the world of sorcery.

During my time at a vocational college.

Gojo Satoru: "I never imagined that besides my six eyes, there would be someone else in this world with a pair of special eyes!"

Xia Youjie: "Because you are Dongfang Hao, you are the strongest. Or is it that you are the strongest, and that is why you are Dongfang Hao?"

Lu Suo: "One Six-Eyed was enough for me, and now there's another one, Dongfang Hao!"

Rime: "Lord Sukuna, you said you would win, didn't you?"

The introduction is insufficient; please read the main text.

The main text is finished (there is no system, and there is no CP in the main text, so you can ship whoever you want, it is seriously ooc, has a lot of private settings, and is probably slow to warm up?) After Nishimiya Shizuka inherited the shrine from her grandmother-in-law Miko, she struggled for food every day. When will this life of having no food to eat end?

Just when they were in such a dire situation, Miss Jing picked up a deformed baby with two pairs of arms in the back mountain. The moment she picked up the child, a screen of barrage appeared in front of her eyes.

Shrine maiden Shizuka was brutally murdered? Is this child a future villain?

Jing thought it was God's gift to her, but in the end she still couldn't escape the disaster and said, "I'm going to go crazy!"

(It is divided into Heian-kyō and modern chapters. There are sweet stories and swords. All ooc stories are mine. I am an old man from the mortal world. I am a novice writer. There are bugs. Please be kind to me.)

I, Jiang the Slime, unexpectedly found myself in Overlord, but with no goals in mind, I'm just waiting to die. This world is a sequel to Ainz Ooal Gown and Sword Art Online. This is just a small world; our goal is the stars and the sea!!!
