In the game "Super God": 800 Astartes at the start

In a world where the Warhammer 40k universe has been recreated, Fang Xu finds himself transmigrated into the realm of Saint Gilles, only to discover that his ultimate fate is still inescapable. Despite his efforts to evade it, he is severely injured by the gods Puff and Horus, leaving him on the brink of death. Miraculously, he awakens to find himself in a new reality, surrounded by hundreds of Astartes in yellow armor, who hail him as their father with a mix of shock, joy, and caution. As he navigates this unfamiliar world, he receives notifications of system binding and chat group invitations, which he utilizes to accumulate power and embark on a grand expedition to unify the Earth and conquer the galaxy. With the system and his newfound allies, Fang Xu sets out to incinerate the aliens, spread the glory of humanity throughout the universe, and ignite a revolution that will leave the stars burning.
