The God Of Immortal law

The huge magic empire spanning tens of thousands of galaxies has encountered the most terrifying enemy in 100,000 years.
In the face of an overwhelming army of mechanical civilizations calculated in trillions of dollars, even magic civilizations that have multiplied to their peak state can only survive.

Unexpectedly, when I woke up, I returned to the era of 100,000 years ago when the Human Race had not yet left the home planet with half a godhead.
In one hundred thousand years, Human Race still has one hundred thousand years to escape the future crisis of genocide.
