【Fate fanfiction, Charlemagne as male lead, includes original characters and settings—if that’s not your thing, please avoid reading】

The author is extremely amateur, the plot isn’t particularly tight, and the romance is kind of awkward.

If this causes you a bad reading experience, I can only apologize—

I’m truly sorry! bows repeatedly

———Now for the serious synopsis————

As an ordinary person, Fujika Tsukizuki suddenly found a Command Seal appearing on the back of her hand, marking her as a Master chosen by the Holy Grail.

With a “might as well try” attitude, she half-casually and half-seriously aimed to summon her all-time favorite Servant—

and somehow, she actually succeeded.

“Wait… could I actually be a genius at magecraft?”

“But hold on… who in the world summons a Servant using merchandise?!”

Traveling through a parallel world, Luo Han became the boss of Mihoyo, a company on the verge of bankruptcy.

At this moment, he accidentally awakened the time-travel system, which allowed him to invite game characters from the original world to visit him.

He first tried to invite Nashida to Blue Star, and from then on he came up with the idea of making "Genshin Impact".

Let Nashida shoot the character PV "Happy Birthday" first, and make all the players on the Internet cry!

"Genshin Impact" has unsurprisingly become a hit on the entire Internet. At the same time, as more and more Genshin Impact characters have traveled through time and space, the company's painting style has gradually become strange.

"Lei Dianying: How dare you say I can't cook? Look, I'm going to chop this rice fool into pieces with my Wuxiang knife!"

"Kamisato Ayaka: I want to protest! Why do people laugh at me and call me 'Da Jia Gui Xiu'?"

“Ganyu: Stop talking about my dark history as a child! If you do, I’ll let you guys have a taste of how powerful Teyvat RPG is!”

"Hutao: The Blue Star branch of Wangshengtang officially opens today! Grand opening promotion, buy one get one free!"

"Dolly: Dolly's magical shop has everything. Don't miss it if you pass by!"

【Fate + Holy Grail War + Cao Cao Doctrine + Type-Moon + Romance!】

Why is loving a single girl considered "pure love"...

But loving a married woman isn’t?

Is pure love really that limited and restrictive?

My love for these wives is genuine, beautiful, and untainted!

Their husbands? They’re the only obstacles standing in the way of my true love!

Besides...

There are tens of thousands of guys chasing after single girls,

But chasing a married woman? There’s only one man to beat!

I’m just too weak to fight the whole world—so I’ll choose to face only one rival at a time~~

...

Zhong Xuan transmigrated to the world of Type-Moon in the year 1994.

There, he awakened the "Cao Cao System" — the more famous characters he cucks, the stronger he becomes!

Thus, his performance began...

“Madam, you wouldn't want to...”

And in no time at all—

Tokiomi Tohsaka, Kiritsugu Emiya, Kayneth, and other legendary men…

Suddenly found a vast green meadow sprouting above their heads.

Morpheus, who had traveled to the world of "A Certain Magical Index," was still sorting out the mess left by an evil magic society when he was caught in a space-time turbulence and transported to the world of Type-Moon. He was reborn as a baby, adopted by the Macremis family, and Bazette's younger brother. As he prepared to fight the Fifth Holy Grail War, he discovered that this world was actually the FGO world, where the Fifth War had never existed. So, for the sake of world peace and to once again pursue the ultimate secrets of magic and become a demon god, Morpheus Fraga Macremis, a golden-type magician, embarked on a journey to save humanity.

Having traveled through time and space, I've gained the ultimate Heroic Spirit Avatar Legion System. The future of sweeping the world with an endless army of clones is just around the corner!

But... why are there only female Heroic Spirits?

...

"Can you tell me how you managed to find so many loyal and beautiful wives?" Fujimaru Ritsuka asked, stunned.

"It's mainly because... we're all connected."

Surrounded by beautiful women, Bree looked away awkwardly.

(Note to those in the audience: The male protagonist can transform into various female Heroic Spirits and use Heroic Spirits as clones.)

At the beginning, I encountered a star train that was as powerful as a monster that I couldn't defeat. I was reborn as a star core spirit and I must take everything back in this life.

But why is it not the sky but the stars? Well, there is always a trade-off. It is not impossible to become a star.

What does this mean? This is Fuyuki City.

Okay, okay, so this is how it’s connected.

The Type-Moon World is a unique parallel world.

In this world, there are Heroic Spirits, vampires, gods, and all kinds of supernatural beings.

There are conspiracies, schemes, factional struggles, and even the descent of Outer Gods!

There’s Saber’s Excalibur!

There’s Rider’s Bridle of Chivalry!

There’s Illya’s lively charm!

There’s Matou Sakura’s ultimate redemption!

There’s Tohsaka Rin’s tsundere pride!

There’s Medea’s transformation!

There’s Cú Chulainn’s Luck E!

There’s Sun Wukong, Wu Zetian, Qin Shi Huang, Shuten Dōji, Yu Meiren, and… so much more!

Servant Lancer Remlia Scarlet... Queen of the Night, reigns here. From now on, I will be your master, servant, are you type B blood?"

"Servant Saber Akame, in response to our previous meeting, nice to meet again, Master."

"Archer Misaka Mikoto, eh, do we know each other? Hey, hey, hey! Master, your pick-up method is too old-fashioned."

"Servant Saber, I came here in response to the summons. Well, just call me Kirito."

"Servant Archer, my name is Tokisaki Kurumi. Ah, Koizumi-kun, we are also an accomplice who saved the world together. Why are you hiding from me like this?
