[Time travel + System + Invincible protagonist + Warhammer reference + Father-son daily life + Invincible young hero]

I woke up to find myself the most miserable Primarch in the Warhammer universe, Guilliman!

At the start, the Eldar stabbed him in the neck with a knife, the Chaos Legion attacked him head-on, and his own offspring clung to a broken holy book from ten thousand years ago.

Luckily, I have the "Strongest Regent System" with me, and I merged with Regent Witrum at the start! I stopped the Thunderhawk with my bare hands, traversed warp space with my bare body, and crushed a Chaos Can with a single punch!

Abaddon: "How could he possibly be resurrected?!"

Tzeentch the Demon: "He dragged me out of warp with his bare hands!!"

Ultramariner: "Father...why are you taking out your belt?!"

Guilliman grinned: "Good boy, today Daddy will teach you what 'fatherly love is as solid as a mountain' really means!"

With all the Ultra Warriors upgraded and empowered by intelligent atoms, their offspring are all little superhumans!

The Khorne's army? Crushed! The filthy tide of corruption? Purified!

A treacherous scheme? I'll drag the real me out of the warp with my bare hands and slap him across the face!

Slaanesh is below, the Regent is above!

Guilliman shattered the Eye of Fear, grabbed the heads of the four evil gods, and threw them onto the Golden Throne: "Father, you didn't beat them hard enough or fast enough back then! This generation of Chaos—needs to be whipped with a belt!"

[My thinking power + Orcs + Time travel + Conquest + Joy + No female lead]

It starts with a green-skinned kid, and ends with him smashing through countless worlds.

What? Your unit is an angel? A dragon? A vampire?

Don't laugh at me for having only a little green kid. In a couple of weeks, you'll understand the meaning of "endless"!

A race born for war!!!

One green-skinned beast falls, ten thousand are born!

What faith can lead to godhood? What technological advancements? Nothing beats tens of thousands of green-skinned bastards believing that I am big and strong!

I think our lord is invincible!!!

I'm thinking a level 7 civilization could be created by hand!

Orcs were born to feed humans, and humans used a single punch to crush the heavens!

Vast, vast, vast, vast, vast, vast!

"Mao was both brutal and cunning!!!"

“WAAAAAAAAAAAGH!!!”

"WAAAAAAAAAAAAAAAAGH!!!"

The Navigator's Son, a futanari hermaphrodite, possesses striking beauty, at least at first glance not frightening to others in Warhammer. His body is mutated, appearing more transparent and gelatinous like a slime girl, with five Navigator's Eyes on his head. These were twisted into a crystal-like form by the evil god and then purified by the Emperor into a four-winged, soaring eagle. If he were a born immortal, his regular psychic abilities would be below Alpha level, just short of it. His bursts of power would reach a level that would impress the Emperor. He was discovered and purified by the Emperor when the Four Vendors casually applied twisted psychic energy, unleashing an extraordinary psychic power that alerted the Four Gods and the Emperor. After his successful birth, the Emperor appeared in a dream, summoning the Custodians, the Silent Sisters, and the Grey Knights to inspect and monitor him.

Transcending into the Warhammer world. The Middle Ages are a chaotic wasteland, with the shadow of eternal destruction looming over all timelines. The end is nigh, and the grand game of the Chaos Gods unfolds in the Middle Ages. Carrying a simulator, when faced with the choice between becoming Primal Chaos and the Watchers of Order, will you destroy or save the world? In the 40th millennium of Warhammer, endless war engulfs the entire galaxy. The Emperor is long gone, buried on the Golden Throne. The Astragalus and Astartes have paid a heavy price; even the Primarch's return cannot halt the Imperium's despair. The edifice is crumbling, and the Dark Lord is about to rise from the throne. A decisive outcome will change everything, ensuring humanity's glory endures. Conquer or destroy the Xenomorphs, only in the name of Primal Chaos, in the sight of the gods.

A group of sects from the cultivation world collectively traversed the Warhammer 40K universe, their floating immortal ships colliding with an Emperor-level Titan.

The mechanical bishop trembled as he examined the energy reading: "Energy reading...not present? This violates the laws of physics!"

The elder swordsman cleaved the Chaos Egg in two with a single sword strike, causing the psionicists to collectively collapse: "They are unaffected by warp contamination!"

The alchemy master boiled the green-skinned beast into a foundation-building soup, and the orc boy cried out, "Boss! The soup is so hot, but I've become smarter!"

When fanatical followers of the state religion burned "heresy scriptures," the cover of the *Tao Te Ching* suddenly shone with golden light:

— "High-dimensional philosophical concept detected... Warning! Logic engine overload!"

I unexpectedly traveled to the late Eastern Han Dynasty, but... why is this so different from the history books? Back then, the Han Dynasty was a land of galloping horses and cavalry on the grasslands, haunted by ghostly figures at midnight; serpent monsters lurked in deep pools, and fox spirits roamed the mountains; powerful families monopolized magic, and the Han emperor and princes transformed into dragons. Ten thousand demons, all carrying Han Dynasty green cards, proclaimed how powerful their empire was. Millions of people donned yellow turbans, wielding thunder and lightning, calling themselves the Thunder Warriors of the Yellow Heaven, and establishing thirty-six war generals across the nine provinces to lead the Yellow Turban Rebellion. From the Taihang Mountains to the seven commanderies of Jingzhou, they caused rivers to boil, destroyed cities, and set the empire ablaze. I wonder if half of the war generals will betray the Yellow Heaven someday. Okay, a little strange is a little strange, but... why are all these renowned figures from the late Han and Three Kingdoms periods all women?

A hardcore player with the "Stellaris" panel crushes the Chaos Gods with absolute order in the despairing Warhammer 40K universe by managing colonies, climbing the tech tree, and building an invincible fleet.

In the third millennium, Immor, located on Holy Terra, crafted a Warhammer prize box. The day after its completion, a city materialized within the box, where a group of thugs were committing crimes. Driven by a sense of justice, Immor decided to punish evil and promote good, thus setting in motion the threads of fate. The Emperor both loved and hated Immor; love stemmed from the appearance of a second beacon in the dark human world; hatred arose from the latter's theft of his son, much like the Four Gods. Khorne was enraged by the theft of his title as the second brother. Nurgle wept in anger at the theft of Aisha. Death, in league with Immor, terrified Slaanesh. A second Weaver of Fate appeared, driving Tzeentch mad. A product of humanity's 2K era, Tal Rashin was ecstatic. A certain sunny and cheerful young man...

Everyone travels through time to build their own mobile cities, painstakingly gathering resources and leading small armies to wipe out enemies. But I have a 10x cheat code, enjoying wealth and luxury to the fullest.

What interesting things would happen if the Primarch and the Emperor watched footage of the future together?

They will witness the death of heroes, the fall of the vile, the truth of the warp, and that distant, dark future. And what decisions will they make afterward?

(This is a story written by a new author out of love, so the synopsis is inadequate. The story will mainly focus on the Empire and the Primarchs.)
