Human hearts had been lost.
The blood sacrifice of the Myriad Demon Sovereign, treating everyone as less than human, completely prompted the empire to revolt; they would rather become slaves to the Divine Martial Great Emperor than to oppose him.
The Myriad Demon Sovereign didn't care at all.
In fact, when he founded the Myriad Demon Empire, it had always been for this purpose; by nature, he was a demon, selfish and self-serving.
"Wish to become his slave? Impossible. Once I have completely sacrificed you all, he too shall die!"
Within the Myriad Demon Empire, an even more terrifying immortal will empowered his strength, as if some dreadful being was about to drill out from one space-time to another.
"I curse you to a terrible death!"
The cosmic god of the wasteland universe screamed miserably, as if foreseeing his own demise, wailing in sorrow.
"Your curse is effective, I don't know how many times I have died," said the Myriad Demon Sovereign, disdainfully.
