Return of the Blood Autarch [OP MC, Reincarnation, Cultivation]

In an era where humanity was trapped in an endless interstellar war, Azrael stood at the peak of mankind as the Blood Autarch, a warrior whose name alone was enough to shake battlefields. But even he eventually died. His soul ascended into the Soul Realm, where he learned that existence was far greater than he had ever imagined. The Mortal Realm was only the beginning. Beyond it stood the Soul Realm, and beyond that, the Heaven Realm, a domain unreachable to those without a true physical body. Driven by an ambition that refused to fade even after death, Azrael rose as a mere mortal soul and challenged the entire Soul Realm. He faced its five eternal rulers, defeated them, and conquered a realm no mortal soul was ever meant to rule. Yet despite his absolute power, he could not enter the Heaven Realm without a physical body. To continue his path, Azrael sacrificed everything he had gained and chose rebirth, returning to the Mortal Realm. Back at level one, in a strange new future, Azrael began his journey again, driven by a single, unshakable obsession. "Of all realms within existence, I will be the strongest!"

AI-Assistance Note: This novel is tagged as AI-assisted only because AI is used to help correct grammar mistakes and occasionally rephrase awkward sentences, since English is not my first language, and I am still improving. Other than that, nothing in this novel is generated by AI. The raw chapters, story, characters, screenplay, worldbuilding, and plot are written directly by me and my friend.
