Ten thousand years ago, I witnessed the destruction of a civilization, the shattering of memories, and the arrival of an end. At that time, I was powerless to stop it.

Fifty thousand years ago, I felt a familiar civilization, familiar things, and familiar people, but the memories that traveled through time were not in my mind. I watched as the end destroyed civilization once again, but I suddenly regretted it.

And now, the power to save everything, all the memories of the past, are within me. This time, I don't want to lose them again, nor can I lose them. I will grant your wishes and make this world beautiful again.

Sing joyfully, all things in the world, to welcome the death of your god, who will bring boundless beauty to this world. What, "you" refuse? No, no, no, you have no reason to refuse any of this, nor is there any room for negotiation.

An unexpected event transported Su Ye to the world of Collapse Iron, where he arrived in front of the Starry Sky Train, which was still stranded.

Just as he was at a loss, the Multiverse Commission System was activated, and he became a Multiverse Adventurer, while also binding the Starry Sky Train to his vehicle for traveling through the multiverses.

And so, a novice adventurer, fresh out of the gate, embarked on his adventure of creating and flying through countless worlds, piloting his ghost fire train.

And the first place to be launched into the air was the world of Iron Collapse:

At the site where the Starry Sky Train ran aground, the lost Himeko was abducted.

Learned Master: ?

During the Five Hours in the Clouds, he saved Bai Heng from imminent death and invited him into his carriage.

Learned Scholar: ? ?

Save Arillo-VI from the invasion of the antimatter legion and change its future.

Bo Shizun: Tonics are creating possibilities! Damn it!!

Save Onpharos and prevent the birth of the Iron Tomb.

Bo Shizun: I already said no... Hmm? This is an option.

Nanook: This is unacceptable!!

After messing up the worldline of the Collapse Iron Universe, Su Ye turned his gaze to the myriad worlds beyond the Collapse Iron Universe.

All beings: Please, please don't come any closer!!

Su Ye: What are you babbling about? Go talk to my Starry Sky Train! We're all living life to the fullest!!

Jun Qing, who transmigrated from another era, has experienced countless years and possesses many identities. He inexplicably arrives in the pre-collapsed civilization of the Honkai world with the Gates of Hell and the Eight Great Demons.

After the end, Jun Qing became the captain again. He changed the regretful fate of all worlds. In the long time he had traveled, this was perhaps just an insignificant moment in his journey to the myriad worlds. After the end of the previous civilization, he awoke and traveled with Yuexia to the world of Akame ga Kill! and then to the world of Genshin Impact...

[Starry Sky Railway] [Funny and entertaining] [Multiple female leads] [No system but invincible]

Xu Zixuan travels through the Collapsed Iron City.

Bad news: I've only just transmigrated here, and I've already attracted the attention of a robot-headed guy, a peeping tom, and a fun-loving guy.

Machine Head (Bo Shi Zun): A being from outer space, possibly from a world beyond the Tree of Imaginary Numbers.

Voyeur (Fu Li): Unable to see the other person's memories, secretly hides away.

Laughing Person (Aha): Aha, this is really fun, let's go.

Good news, Ahabah has made a move.

Xu Zixuan crashed directly in front of Kafka and Silver Wolf, who were doing bad things at the Black Tower Space Station.

Kafka: (Word of Power) Listen to me...

Xu Zixuan: Mom! I'll do whatever you say?

Kafka: ?

Silver Wolf: The vessel is ready, you decide!

Reminder: This book is a multiverse story with an ensemble cast. The main character won't have many direct scenes, and the various parts aren't strongly connected. Just choose the parts you like...

The protagonist of this book is more like a behind-the-scenes manipulator. He mainly writes about the changes that occur after the various worlds merge, and the impact of these worlds being integrated into the Honkai Iron.

Chang Heng transmigrates to the Starry Sky Railway World and is reborn as a deceased immortal star god. Relying on his cheat ability, he merges the Collapsed Iron World with other worlds in the myriad realms.

The main storyline generally follows the sequence: Immortal Boat Luofu → Pinocchio → Martial Arts Ceremony → Onpharos...

At the same time, Honkai Impact 3, Genshin Impact, and other worlds (as well as other worlds in the myriad realms) will merge with the Starry Sky Railway world at different times under Xuan Yuan's intervention.

When the protagonist's concept, time and space, cause and effect, or reincarnation reaches eternity, they will have the ability to resurrect the deceased, and characters from other worlds that merge into them will also participate in the storyline of the Starry Sky Railway universe.

There may be many factors involved, and this is written from multiple different perspectives.

It has a system, and it mainly profits by altering the plot.

The worlds that have been merged so far are: Honkai Impact 3 (past time) and Genshin Impact.

Other worlds already involved: One Piece and Detective Conan fusion world, Sunday, Poteo, and Ranpo have been entered.

Characters from Marvel, Church of America, and Saekano are currently connected through a chat group created by the main character.

The protagonist establishes the Heavenly Abyss Palace, using the four eternal buildings—the Spirit Order Dharma Pavilion, the Profound Abyss Time-Space Tower, the Eternal Calamity Palace, and the Reincarnation Palace—as foundations to build four eternal forces (not all of them have appeared yet, and they currently have limited screen time).

He transmigrated to Changkong City, where the Honkai had erupted. Sikong was dead. But not completely dead. He could transform into any Honkai Beast—from a Super-Advancement-class to a Chariot-class, then a Temple-class, and even Valkyrie Kiana, Raiden Mei, or Bronya—provided they killed him first. Sikong: "Humans! I'll protect you!" Himeko Murata: "In a way, you're more pleasing to the eye as a Honkai Beast. If you dare to transform into me and do anything strange again, I promise I won't kill you." Kiana: "Um... can you transform into a Honkai Beast for me to ride?" Bronya: "Bronya came first, Sikong should grant my request first." Raiden Mei: "Kiana, Bronya, you two stop bothering Sikong, come and eat."...

Black Ruler, a reborn individual, transmigrates into a corrupted world. Bronya… a perfectly normal start. He sees himself as a tool, a mere agent and nanny, destined to gradually get to know the other three starter families. But things get increasingly strange… Benares, his former nemesis. “Dad?” No… wait, that’s too abstract. Cheng Lixue, disciple of the immortal Fu Hua. “Benefactor?! How are you still alive?!” I wanted to ask you how you’re still alive… Raven, executive of the World Serpent. “So you’ve forgotten what you said to me and him back then?” That… [Carola]

Waking up, Su Han found himself transported to Changkong City. Just as he was about to flee, he encountered a suicide squad member. He was doomed. Luckily, at that moment, Su Han received an invitation to a chat group. A brilliant idea struck him, and he sent the...suicide squad member as a red envelope. "The Prophet has received your red envelope." "Fool's Last Seat: Group owner, great speed!" "Time Elf: Group owner, great speed!" "...The newbie is quite savvy, knowing to show respect to the big boss. In that case, this prophet will give you some pointers... Ah—help—" "Ding, warning, group owner is dead..." "The chat group is about to restart; a new group owner will be elected."

[Multiple Female Leads][Modified Plot + Original Content][Aha is also a Female Lead!] Su Yun, the messenger of the Pleasure Star God, couldn't understand why, despite working for the Star God, other Star Gods enjoyed a life of luxury while she was constantly being blamed by Aha. "So next time you do something bad, can you not blame it on me?" "Heh, no way." Aha sincerely refused Su Yun's request. If she weren't outmatched by Aha, Su Yun would have already smashed a Luoyang shovel over its head! Under Aha's "careful" guidance, Su Yun gradually assimilated into the Pleasure Star God's direction. Kicking the Destruction Messenger, punching the remnants of Abundance, secretly manipulating the script, making everything...

Good news, I was killed by a train at home.

Even better news: he's become the navigator of the train.

Even better news is that you can travel to the world of anime by train.

What pioneering and interesting things did you do after becoming a navigator?

She was paired with Kirito.

Adopting Lolis from All Over the World

Discussing the relationship between monarch and subjects with a famous queen

The birth of the king was celebrated with a cannon salute; God was lured onto a train; and Shiori almost fell in love with him.

Do these count?

Worlds experienced: Sword Art Online, Black Bullet, Akame ga Kill!, Date A Live, High School DxD, Guilty Crown, Academy Battle, Accel World...
