This is a fanfiction of Rimuru and a pseudo-fanfiction of Ainz Ooal Gown. Lin Ming, possessing the Nazarick Great Tomb system, is summoned by people from another world. In Rimuru's world, he summons Albedo, Demiurge, and others one by one, and establishes a dynasty two years ahead of schedule in the eastern part of the Jura Forest. When Rimuru establishes the Demon Kingdom Federation in the western part of the forest, he discovers that his older brother is actually incredibly powerful. Thus, the story of the older brother and his younger sister... no, his younger brother, begins! What kind of interesting stories will unfold when two Demiurges appear at the same time? What strange sparks will fly between Shalltear and Luminas, both true vampires? The early part of the story is a slow-paced, hellish development for the protagonist, so please be patient.

El is a drifter. He doesn't aspire to be the Pirate King, nor does he seek the One Piece; all he cares about is increasing his stats. A low-key system, a devout individual. —————— Pirates aren't child's play; pirates can be on the same ship as long as their interests align! The head butler, Visa, brandishing a sword, asked the crew, "Do you want to rescue the captain in Impel Down? Raise your hand if you disagree, and then wait for Captain El to come out and kill you." Before going in, I had no dignity? After coming out, who dares disrespect me! El Mordis, the captain of the Angel Pirates, the Blood Calamity, the mastermind behind the underworld. He once said, "The blood I shed, even the sea level has to rise a centimeter to give me face."

One day, I was transported to a parallel world.

Lu Yu was told by the system that in order to activate the system, he not only had to take the college entrance examination, but also had to become the top scorer in the college entrance examination!

After finally making it to the moment to check my results, I thought I was about to activate some high-end, awesome system, but the situation took a sudden turn.

What he activated was... the Peerless Knight System?!

Isn't this supposed to be a harmonious parallel world? Why did the art style suddenly change?

After the system was activated, Lu Yu suddenly realized that this world was far more complex than he had imagined.

This world hides many knights he knows, as well as... weirdos!

Zerg: What the hell?! How come this guy's speed is even more outrageous than ours?!

Orfino: What?! How did the Heavenly Emperor and the Earthly Emperor suddenly appear?! Aren't we still studying them?!

Many knights: This guy is so strong... is he really not here to cause trouble?!

The world has inexplicably changed; Mai Sakurajima, Misaki Shokuhou, and Misaka Mikoto suddenly appear. Why can he still connect to another world? The Holy Grail War; the Apocalypse Virus; the labyrinth city of Orario; the Teigu users; "The world is so chaotic, since I've become a demon, I should be cunning, cruel, and tyrannical, that's how it should be..." But these girls before him are not only not afraid of him, but their faces light up with joy upon seeing him; the demon falls into deep thought...

He transmigrated to the Naruto world and became Naruto. Although he became Naruto, he didn't have a system. However, he unexpectedly found a Flying Thunder God kunai with a spiral-patterned gem in the back mountains, inadvertently initiating a cross-time dialogue with Minato Namikaze, who hadn't yet become Hokage, triggering a chain reaction of historical collapse in the ninja world. Main characters: Naruto Namikaze, Minato Namikaze. This book is also known as *Naruto: Black Hole Frequency*, *Naruto: The Butterfly Effect*, and *Naruto: The Scar of Heaven*.

Hayata Susumu, transported to the aftermath of the original Ultraman series, initially thought he was on the path to Ultraman, but a group of scientists suddenly appeared and captured him for experiments, claiming he was Ultraman's human host. Just when he thought he was on the path to Ultraman F, the scientists found nothing on him and had no choice but to let him go. As he decided to live as an ordinary person, a new crisis confronted him. Seeing the mechanical Ultraman created using human science, and King Joe closing in, Hayata Susumu realized: he was on the path to Gundam! This is a story about humanity protecting the Earth through its own efforts after Ultraman's protection is gone.

At the end of the season, I was transported to countless worlds, splitting into numerous parts, all of which were of hellish difficulty:

The city, but mysteriously revived, a world rife with evil.

The sky was covered, but darkness and turmoil reigned, and all living beings were slaughtered.

Honkai Impact 3rd, but Honkai Impact 3rd Academy, a happy ending!

Stars, fifty years of life, the first research vessel has just set sail...

Journey to the West, at least, isn't a dark myth; it's even worse than a dark myth!

In ancient times, it started with the character "青" (qing), but it didn't refer to Qingmaoshan.

Mei is there, but how was that black sun in the sky depicted?

………

I don't know if I destroyed the world in my past life, but none of the worlds that Ji Mo has traveled to are simple. Anyway, in order to survive, Ji Mo from all the worlds has united to become one family!

"Since you don't want us to live, then none of us will live!" Ji Mo said.
