Having transmigrated to the world of the Starry Sky Railway, Su Bai obtained the Super Dimensional Auction House, which allows people from all over the world to participate in auctions.

Among his auction items were many precious treasures, but the most precious were the fates of his guests.

Black Tower: "Huh?! You're saying the machine head is going to die, killed by the Iron Tomb of the Annihilation Lord?"

Alicia: "Is this our final ending? It really is a romantic story♪"

Tianli: "Me, knock? My men have all rebelled?"

Aizen: "The universe is so vast, yet my eyes are only focused on the Hogyoku. That's far too narrow-minded."

Luo Ji: "Is this a trap set by the Three-Body Problem? Huh, what the heck is this two-dimensional foil?"

Thanos: "Star God? Is he strong? How does he compare to the Infinity Gauntlet? Oh, and you even have Infinity Stones to contend with?"

Batman: "There's a Kryptonite auction? I'll take it..."

Feng Baobao: "The rat talisman I filmed is so much fun... but it's also very expensive!"

Su Bai: "You all say my auction items are ridiculously expensive, but who knows how hard I worked to find them!"

I was reborn into another world, starting as an unknown duke's son. I began to distinguish myself in my first year of university, developing a complicated relationship with a princess. I also discovered other transmigrators and learned about various cultures: beast-eared girls, elves, succubi, and, importantly, dragon knights. Ultimately, I built a nation in this other world where different races lived in peace.

[Otherworldly Soul Transmigration, Swords and Magic, Lord Battles, Farming and Money Making, Quest System]

The story of a soul transmigrating to Middle-earth in the world of Might and Magic, becoming a descendant of a fallen noble family, using the experience of his previous life to rise from slavery to lord, befriending various forces, and vying for supremacy over Middle-earth.

This book combines elements from Might and Magic, Heroes of Might and Magic, and Total War.

Lanny always believed he had transmigrated to a chaotic, backward, impoverished, and ignorant ancient Europe, and that he was just a minor nobleman from the countryside. However, he soon realized something was amiss. This world also had legends of magicians and vampires, but it was more than just legends...

[Squad Adventure][Pseudo-D&D][Hybrid Worldview] Raine arrived in a fantastical world and obtained the "Adventurer's Chronicle." Slaying monsters made him stronger, exploring made him stronger. From then on, he was unstoppable, becoming a low-level adventurer. From dark forest secrets to lost ancient ruins, from dungeons beneath the yellow sands to floating cities in the clouds. He traversed snow-capped mountains, forded valleys, paused beside the corpses of demon gods, and gazed into the distance from the backs of dragons. Until one day, he touched the supreme crown on his forehead, looked at the thousands of beings kneeling before him, and sighed deeply: Adventure has no end, adventure never stops.

—For those readers who want to avoid pitfalls, this is a mixed fantasy novel with a single female protagonist and a slice-of-life story. The author believes that magic is not something that can be accomplished simply by imagination. Otherwise, what would those legendary mages who have been studying it for so long be researching? Therefore, it will contain a lot of complex magical academic theories.

—If you don't want to explore how magic comes about or how it's used, and feel it's pointless, you can leave.

—Those looking for a harem story can leave now. This is a single-character story with a female protagonist.

—Those who wanted to become gods can leave now. I just wanted to live a simple yet fulfilling life.

—It's set in the Middle Ages, but not that dark. It just illustrates that the world had a low level of productivity. The style of houses, clothing, etc., conforms to "ancient Western times." Don't force reality into it. If you're looking for dark stories, you can leave now.

—The characters are good people, the king is a good king; not everything is about tyranny and slavery. Reality is already hard enough, so I like good people, and I like happy endings. Those who want to find fault with the protagonist can leave now, because no one is targeting the protagonist, and there's no face-slapping.

—This work references many other works, but it's not a fanfiction of any particular work. I hope that since you're reading a novel, you'll take my version as the standard, since many fantasy works are based on games, and games are for playing, not for real life. There are many things I need to rationalize. If you can't accept this, you can leave.

—The opening has a connection to the world before the transmigration. If you feel that the poison is gone, you can leave directly. If you want to continue reading, I can clearly see that this connection, apart from the divine consciousness, does not affect the later text. So there is no need to teach me how to write novels and say that this part is superfluous. I wanted it to be there, so I wrote it.

This book is also known as "I Do Whatever I Want in the Honkai World," "The Herrscher of the End Wants Me to Build a Harem," "Honkai Simulator? I'll Go For Real," "Challenging Seven Valkyries in One Night," and "Durandal in Training." As a white-collar worker, without shaving, I came home from get off work to find a beautiful girl I'd picked up. It turned out to be Kiana, my wife whom I'd watched grow up?! After living with her for a while, I was transported to the Honkai world after the main storyline ended. Surrounded by Herrschers and S-rank Valkyries, my work turned into spending every day with my wife?! And what's even more outrageous is that they, whom I have a lot of affection for, actually want to help me grow my harem?! Every morning I wake up to see Mei on my left, Yuexia on my right, Airi at my left foot, Rita at my right foot, and a big duck in my arms! Then I try every possible way to "act unreasonably," but they all willingly satisfy my unreasonable demands. Even if I said Mei was bouncy in front of Kiana, let Bronya answer the phone while I was on a date with Seele, and even made Ellie only watch me and Eden...
