(Spoilers + Time Travel + Multiple Realms, a spoiler-heavy variant, proceed with caution if you dislike spoilers!)

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!"

[Broken Iron] + [Live Broadcast] + [Comics] + [Challenge Monsters] A light curtain projects the story of Star Dome Railway to the heavens and the myriad worlds. The natives of each world are all amazed at the power of the star god, the vastness of the sea of stars, and the abstractness of the stars... Just when everyone can only see a novel story from the sky curtain, the opportunity to challenge monsters quietly comes. In addition to allowing them to better understand the world of Star Dome Railway, it also gives them the power to change their destiny. Regarding the strength of the monsters, Yingqiang, with trembling hands, smiled and said-very simple! (PS: The worlds I wrote are all those I have seen or played. I try not to be OOC, but it may be difficult to avoid. I hope you can understand. Finally, I wish you all a happy reading)

(Transformation + Single + Daily Life + Mischief + Summoning) Crio Schariac swore that if she could do it all over again, she would definitely avoid time travel, because the price of time travel was losing her brother. First, she was transported to Honkai Impact 3rd and became Cecilia's younger brother, then she inexplicably traveled to the Black Tower Space Station, and even became a girl... Who can she complain to? Fortunately, she has some acquaintances here. Welt Yang: "Crio?" Crio: "Yeah, it's been a long time, old Yang..." Welt Yang: "...I don't know why I want to say something." Crio: "?" Welt Yang: "Damn it, the Honkai is still chasing me." Crio: ... But time travel also has its good points, namely that she can see her friends again...

Sent to the Star Iron World by Dimension Slash, I'm sorry that I couldn't let Optimus Prime do his best to pray for Qiong. Only half of Qiong remained - Qiong.

Why is there still a star in the world line with Qiong?

Who can resist the call of the stars?

Bound to the game system of Honkai, but, system, is there something wrong with your Valkyrie character card?

'Qiong' looked at the confused gray-haired young man in the field of vision, and stared down at the bright red stigma on his chest.

In the Black Tower Space Station, the dream butterfly girl from the Fantasy Sea made Silver Wolf obsessed.

In Beloberg, (Honkai III) Big Duck: "Everyone, the situation is urgent now, let's kill the traitor Cocolia!?"

In the Immortal Boat, Li Dazhentou looked at the living Li Sushang, who was like a sword fairy, and said, "Do I, do I have a twin sister?"

In Pinoconi, Huang Quan looked at Aunt Mei, who was almost exactly the same as himself, and the smiling and lively white-haired girl next to Big Mei, and fell into a long silence. Is this a dream?

Eden and Robin discuss music.

Wuliangta Himeko and Himeko drink wine together.

Alicia and the girl named Xilian...

No one knows that these Valkyries are actually the same person.

And, behind the dome, there is the "automatic AI" that occasionally comes to play for you.

Waking up to find yourself traversing the Star Railway is a joyous occasion, but why are there so many starships around?

After inquiring, I learned that, oh, it turns out I've transmigrated into the Iron Tomb, or rather, the Iron Tomb that has merged with the Great Black Tower. No wonder the perspective is so strange.

Hey, suddenly I felt a chill down my back, a flash of silver light, and then I lost consciousness. Gah, dead!

(Iron Tomb + Great Black Tower = Dark Secret. The protagonist will transform into the corrupted form of the Great Black Tower. Slightly yuri-oriented, OOC, crossover anime, not for those who care about historical accuracy, purely for fun. Please read without thinking and do not take it too seriously.)

A single chat group connects Genshin Impact, Collapse Iron, and Juequ Zero! When the Abyss invades Nata, Dang Xing leads the three train crew members to fight on the Nata battlefield. Dang Ling and Zhe raise their hands to summon talismans to eliminate the Abyssal monsters, while Ying guards the rear to protect Paimon. Paimon says, "Don't charge so hard! Master Pai's wrench is smoking!" In Omphalos, when the Fire Thief's sword strikes Tian, a jade shield rises, followed by a falling star... In short, this is a novel that connects three worlds, and it absolutely doesn't want a tragic ending!!!

"Who is your favorite character?"

"The Great Black Tower, Lady Black Tower is a beauty that could rival the most beautiful women in the world."

Bai Mu gave the answer without hesitation.

"Very good, from now on, you are the Great Black Tower!"

......

An unexpected questionnaire led Bai Mu to travel to the Collapse Iron Universe.

Open your eyes again...

The surgery was a success, and he became her.

It wasn't possession, but becoming another Black Tower... oh no, to be precise, she became Black Tomb.

An intellectual mind pieced together from a destroyed body, memories shrouded in mystery, and finally, a touch of pleasure added...
