Warhammer My Second Primarch Is Invincible

An ordinary modern college student accidentally penetrated the dark universe of Warhammer 40K and became the second Primarch Augustus who was completely erased by history. Unlike other primarchs who wandered in the wilderness, his arrival was favored by fate: he fell into a powerful human empire that spanned 18 habitable planets and was modeled after ancient Terra Rome. When he appeared in the form of a golden baby under the dome of the magnificent palace, the emperor and queen of the empire regarded him as a holy heir given by the gods, and spent all the wealth and resources of the empire to raise him. Augustus, who started with "Good Father and Good Mother", learned how to rule in the grand Roman palace, and witnessed the cruelty of war in the array of the Star Fleet. He must not only stabilize his adoptive father's empire as a primarch, but also secretly accumulate strength to deal with the torrent of the future Great Crusade and the shadow of the Horus Heresy. When the Emperor's expedition fleet sails into this star field, this "Lost Primarch" will rewrite that era of erased history as the successor to the strongest force in the galaxy, and blaze his own path to supremacy in the darkest era of mankind.
