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.

He ascended to the heavens, singing as he went, and with a flick of his finger, he could cover the sky.

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?"

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?!
