When an S-class elite assassin-raised captain of a special ops suicide squad comes home from a high-stakes Africa mission, he finds himself offered something that could potentially set him up for life- a curious assignment that he could use to finally exit his days of war and slaughter.

Then placed into a high-school setting, Lin Yi is tasked by the chairman of a top-tier multi-billion company with bodyguard duty for non-other than his own daughter, a certain little Miss of said high-school.

His enemies, once ranging from drug lords, mafia bosses, political figures, and national leaders, are soon replaced with spoiled kids who happen to have rich papas and mamas, and Lin Yi finds his intense expertise and high-threat skillset misused, and very underwhelmed…

But he does get a harem cast as diverse as his old enemies, so Lin Yi decides that, for the sake of messing around with girls as an invincible entity in a down-leveled environment, leaving his bloody and death-filled war days behind is something he’d definitely want to strive for.

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).

Beichen traveled to Douluo Continent and accidentally obtained a simplified system for all things, embarking on an easy path of practicing and fighting monsters.

So far, Beichen has embarked on the path of simplifying everything, simplifying bloodlines... simplifying rules... simplifying the protagonist's halo... simplifying emotional lines... simplifying emotions... simplifying the position of God...

In the world of Black Clover:

the center of the capital was reduced to ruins. On the burning ruins, Yui Mu was surrounded by the leaders of the nine magic knight groups.

"A loser is not qualified to be a leader."

"Please allow me to reintroduce you, Yui Mu, the second-generation leader of the White Night Magic Eyes."

Yui Mu held the silver magic book and smiled as he performed an unstandard noble salute to the nine leaders of the magic knight groups.

[Survival] [Shelter] [Cthulhu]

The entire population is transported to another world, and Su Yi, as a survivor, is forced to join a survival game.

The eerie dark forest hides countless dangers and opportunities, and the only refuge is the wooden house behind you.

Su Yi, relying on his talent that allows him to freely switch attributes, focused all his attributes on luck when choosing the shelter upgrade system, and unexpectedly drew the Mythical quality Nameless House.

With the selection of the upgrade system.

A whispering hut filled with chaotic murmurs.

The Blasphemous Workshop, capable of performing forbidden modifications on objects.

An unnamed altar dedicated to an unknown deity.

...

As Su Yi watched the bizarre buildings, beyond his comprehension, rise from the ground, he unconsciously swallowed hard.

He always felt that his sanctuary was developing in some strange direction.

Transmigrating to the Douluo Continent, Tianxia Wuzei was dumbfounded—he actually shared the same name as the leader of the four villains in Fruit Warriors!

His martial soul is actually the Explosive King, and he's also accompanied by three treacherous brothers: a traitor, a thief who recognizes his father as his own, and a shifty-eyed fox!

[Ding! Fruit Warrior System activated!]

You'll receive four great mecha spirits at the start: Burst King, Golden Dart King, Sea Shark King, and Magic King!

On the day of awakening, the four brothers shocked everyone—

"One person with full innate soul power? Two innate level nine individuals and one innate level eight?!"

The Spirit Hall deacons immediately went on a bidding war: "Join the Spirit Hall, name your terms!"

The thief grinned: "Sure, but first we need to find out the cause of my parents' death..."

From then on, the art style of Douluo Continent changed drastically—

The Golden Generation: "Why are these four thugs piloting mechs?!"

Tang San: "What happened to the promise that hidden weapons are the best counter to everything? Why are their fists crackling with electricity?!"

Bibi Dong: "...Cross the 'Exterminate the Four Evils' mission off the list and change it to 'Recruit the Army'!"

[Explosive King Possession + Overlord Wind Chasing Fist = Cure Any Dissent!]

"Brothers united can break metal? No, it's like villains running rampant, leaving not a blade of grass alive!"

[Multiple Heroines + Villains + Invincible + Unstoppable Advancement] Upon waking, Ye Mu finds himself transported to a fantasy world, becoming not only the enviable Holy Son of the Hehuan Holy Land, but also awakening a Villain System! By engaging in various villainous acts, he gains Luck Points, which can be exchanged for various items and even used to enhance his cultivation! Just then… the heroine, Su Qianqian, comes seeking medicine for the seriously ill male lead… In that case, don't blame me. "Hehehe, I can give you the holy medicine, but… I have one condition…" [Ding: Detected that the host has successfully captured the heroine, gaining Luck Points…] ———————— Several years later… Ye Mu sits high above the heavens! Beside him are countless women of Luck, each with a unique temperament and stunning beauty… Before him are numerous sons of Luck, trembling and prostrate on the ground… His expression is indifferent, overlooking the heavens… "I am the Heavenly Emperor! Who agrees… who disagrees!" Protagonist: Ye Mu

Ling Miao opened her eyes to find herself transmigrated into a romance novel, becoming a useless cannon fodder female supporting character. She possessed a low-grade mixed spiritual root and was afflicted with a strange poison; besides her immense strength, she was utterly useless. To simply accept her fate, she immediately fled the sect where the female lead resided, the farther the better. Unexpectedly, she ended up in the lap of luxury of another female lead's devoted followers, with everyone in the sect ready to sacrifice themselves for her. Originally, she just wanted to find a quiet corner to be her useless little thing, but her master and senior brothers were all too kind, so she decided to offer a little help. Her gentle senior brother fell in love with the female lead at first sight and willingly became her mobile elixir bank. Senior Brother: "The moment she sheds a tear, I can't help but shed tears for her."

Carl inexplicably transmigrated into the Marvel universe... This is the Marvel universe, a world fraught with disaster. Who knows, while you're sleeping at home, a Hulk might go berserk and start smashing things, inadvertently affecting you in your sleep... There are even aliens and dimensional beings eyeing Earth with predatory intent. Even humanity itself isn't safe; there are always mutants aspiring to be terrorists, and villains trying to control or destroy the world... Even S.H.I.E.L.D., which outwardly maintains world security, is nearly 80% actually Hydra... After receiving the original owner's memories, Carl immediately wanted to use his Chinese identity to go to China, until he heard: 【System Activation in progress... System Activation Complete...】
