[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!"

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.

Nie Feng from Earth, due to heart failure, transmigrated to the world of Demon God's Tale and became Nie Li's younger brother. (The following is a separate, unrelated sentence: "Brother, you have Ye Ziyun enough, leave the rest to me.") Some details have been modified.

Together we resist the Holy Emperor and save the people from suffering.

Let the name of True Invincibility resound throughout the world of Demon Gods and Demons.

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.

In this time-traveling era where luck strikes occasionally, Pei Guang finds himself in luck. He then discovers he can share a professional talent with countless other "me"s. Ultimately, Pei Guang becomes invincible across countless worlds.

Chen Xuan unexpectedly traveled to the Zhenguan era of the Tang Dynasty. He originally thought it was a historical world, but he found that it was a low-magic world with demons and monsters!

At the beginning, he relied on the cheat-like ability "72 Transformations of the Earthly Fiends" to pretend to be a god and deceive Li Shimin.

From Director of the Imperial Observatory to Grand Preceptor of the Tang Dynasty! He established the Tang Dynasty's Demon Suppression Bureau to suppress demons throughout the land!

Let Li Shimin cultivate immortality, let famous generals cultivate martial arts, and let civil officials cultivate literature.

Gradually, the entire Tang Dynasty was transformed into a mythical version of the Tang Dynasty.

To recreate the entire Chinese mythological system.

Cheng Yaojin:

(Back in the day, Brother Chen led me and Lao Qin into the underworld to save His Majesty.)

I wielded two Xuanhua axes, hacking my way from the Gates of Hell to the Bridge of Helplessness! And then from the Bridge of Helplessness back to the Gates of Hell! I hacked back and forth several times, slaughtering the ghostly messengers and soldiers who wailed and howled, their souls scattered in terror. I am...

In the twilight of a dynasty, the court is in chaos, officials are corrupt, the martial arts world is in disarray, powerful clans have risen to power, natural disasters are frequent, evil spirits abound, and the common people struggle to survive. Lin Yuan, now in his sixties, transmigrates to this world. How will he use the black market system to survive in this chaotic era? How will he weave a black market network to influence the entire world, even breaking free from constraints and reshaping the world?

The Seventy-Two Transformations of the Earthly Fiends each possess a unique supernatural power. A magical yellow book sends Li Chang'an back to the ancient world, where he gains a new supernatural power for every demon he slays.

Painted Skin Demon, Zombie King, Spider Demon... one by one, demons fell under his sword.

The supernatural abilities—spiritual communication, swordsmanship, demon slaying—were all acquired from the book.

When he vanquished the hundred demons and looked around with his sword drawn, he realized that it was all just a small ripple before a mighty tide.

[This is not D&D; please do not apply D&D settings to this book.] He's in the Abyss, just woken up! Zou Yu stared at the completely unfamiliar blue sun outside the window, and at the panel that appeared before him, lost in thought. It seemed he really had transmigrated. The problem was, why did this Multiverse Projection System panel look so much like a system function he'd randomly written… wait. This Abyss was also a little different from what he expected?! A bull-horse demon with a horse's face, a three-handed demon with an innate thief's body—what the heck? Did the little minotaur next door have Nigger demon blood in his ancestors, so his father triggered a passive escape before he was born? This leveling-up method also seemed a bit off; leveling up with drugs, electrotherapy for strengthening the body—what kind of setting was that? Okay, okay, so that's how it is, then I can only let you demons and monsters experience what…
