An evil universe invades + Cthulhu is summoned to fight back + wasteland apocalypse from the start + sci-fi epic + mecha.
Never leave the solar system! More brutal than Warhammer. Please prepare yourself before reading.
The protagonist focuses on improving himself, but in the direst moments, he can offer the souls of the powerful to summon Cthulhu deities!
Time reversal only appears in the first few chapters.
The Divine Scriptures record:
The God King has sat upon the sacred throne for ten thousand years!
It is said he has never left his throne, his body forever towering and still as steel!
This has led heretics to claim that the God King died long ago.
But his most devout followers have always believed in him.
When the God King rises and leaves his throne, the primordial energy bursting from him will tear space and time apart!
Then the world will become an altar of sacrifice, collapsing completely into the multiverse!
At that point, he will no longer be the God King!
He will become the Ninth True God!
