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!

My name is Lan Yuxing, a high school student. After dying, I was transported to another world and possessed the body of a slime—Rimuru, also known as the "Cute King," because he's so cute. One day, I discovered that the world I'd been transported to was worse than I'd imagined, because the whole world was so chaotic! The Western Hemisphere has vampires, werewolves, and archangels, while the Eastern Hemisphere has Iron Man and the Hulk. There's also a guy named Luffy in the ocean, and in a place called the Hidden Leaf Village, there are two guys named Naruto and Sasuke who are actually arguing about who gets to fight...

Lin Yu transmigrated to the Uzumaki clan in the Naruto world. After ten years of hiding, he finally awakened the mission system, and from then on...

Mission: To trick Nagato into confessing his feelings to Yahiko.

Mission: Lure Jiraiya to spy on Orochimaru bathing in a hot spring.

Mission: To get Obito to personally meet Kakashi.

Mission: Punish Madara by carrying Hashirama in a princess carry.

...

Lin Yu internally screamed: System, you're acting more and more strangely. Is it too late for me to return this item?

A person is in the world of Kamen Rider Kyokushin, but has traveled through time as Firefly. Kamen Rider? Demon? "Agreement approved, scorched earth operation commenced." "Remember to tell all future generations that it was the Star Core Hunters who sent you on your final journey." When the dust settles, this is just the beginning. In the world of Slash Aka, facing the national guardian Mecha God [Supreme Throne], Clara stands before the one she wishes to protect. "Help me, Mr. Swarovski!" "Leave Clara alone!"

[Spell Return + Twelve Talismans + Invincible Cool Text + Not a Saint]

Jiang Chenyan travels to the world of Jujutsu Kaisen and begins by activating the power of the twelve talismans. The Dog Talisman grants immortality! The Rabbit Talisman grants unparalleled speed! The Ox Talisman shatters all obstacles! Gojo Satoru: "I've never seen your technique before. It's very interesting." Jiang Chenyan wields the Dragon Talisman, and with a burst of flame, he blasts the special-grade cursed spirit into dust. When the twelve talismans are combined, even the curse king, Ryoumen Sukuna, will have to obey my orders!!!

The up and down and the four directions are called Yu, and the past and present are called Zhou.

Due to an accident, Lin Yu died and traveled through time, but on the way, he accidentally ran into a newly created world.

Due to many coincidences, Lin Yu has since become one with the world, his soul has replaced the world consciousness, and his body has become a container of the universe.

It’s a pity that Lin Yu is still in his childhood and has no idea what kind of power he holds.

After finally finding a world coordinate in the endless void, I ended up being bound by that world and my range of activity was limited to a ten-mile radius.

Just when this young dimensional demon was failing in his mission and running into obstacles everywhere, something called a chat group floated into his inner universe.

Becoming a dimensional demon god and getting a chat group of all heavens should be two happy things, but why... why are the group members all kinds of future...

Tang Daoan, rejected by multiple restaurants, was filled with resentment when the God of Luck gently awakened his dormant mind and transported him to the world of Food Wars! He strives to become the world's number one Western restaurant chef, searching for his own recipe for life!

Preface reminder:

1. Time travel, no system, Overlord fanfiction

2. Because the book I like is out of updates, I wrote a new one myself. The plot is not related to the original, but not much. The author follows the principle of "writing a book so that I can enjoy it myself", and has sewn in a few settings from other games. I hope it suits everyone's appetite.

3. It is our responsibility to save the elderly who live in empty nests

4. The author can speak some Japanese. I bought the original Japanese version a few years ago and read it. However, the plot ended before the fall of the kingdom. The author used this as the basis for the secondary creation. If there are any discrepancies with the original, please treat them as secondary settings. Thank you very much~

Introduction

Wen Xiu, who has worked hard for half his life and climbed to the throne of "company management" by relying on his experience in his second life, suddenly discovered one day that this was not Cyberpunk 2077, but the post-apocalyptic real world of the novel "Overlord". After exploring part of the truth of the world, Wen Xiu decided to lay the groundwork for the world, and then followed the protagonist of the original "Overlord" to travel to another world, performing an other-worldly version of "You will return like lightning."

In the other world, being reckless may be fun, but you may be easily killed by the "possible" strong people. Being cautious may help you survive, but is Nazarick really capable of facing a war of the "World War" level?

Therefore, Wen Xiu decided to use the "operational capabilities of the black-hearted bosses in the company's management" + "the completely transformed and upgraded Nazarick" to set off a global storm in the other world belonging to Nazarick and Ainz Ooal Gown!

After losing his life in an accident, he was reincarnated into another world.

Good news: Reincarnation

The bad news: it's a puddle of sand...

The protagonist is a reincarnated being (male in his previous life) with memories of a past life. Reincarnated as a genderless sand monster, his abilities lie somewhere between Rimuru and a lower-ranked subspecies. He stands alongside Rimuru and Veldora, enjoying the protection of both Rimuru and the Storm Dragon, and is treated as an equal and beloved by everyone.

Although the protagonist is genderless, he is mentally male and is judged to be male, just like Rimuru.

He transformed into thousands of forms and reincarnated through countless worlds.

Every reincarnation is the implementation of one’s own path to enlightenment.

In a world of one person, one seeks the truth and the fusion of nature and destiny, opening up the path to immortality.

In the world of Naruto, trace the origin of your bloodline and create your own martial arts.

Ghosts destroy the world, evil ghosts eat people, the seven deadly sins, the suffering of all living beings...

All the heavens and worlds, infinite reincarnation.

I have a heart to prove my truth, for ghosts, immortals, humans, Asuras, demons... I will never give up.

This is a legend of the heavens.
