"Oh. My master's life is dangerously close to being zapped out. How long has it been since I, the Blood Guardian, has been woken up from my deep slumber?" Lucifer...said those words with a look as if he was bored.
Well...it was not really Lucifer who said those words. It was the Blood Guardian, who has taken over Lucifer's body.
This is because Lucifer's life was dangerously close to being zapped out as he said, and the one who is tasked with dealing with situations like these is called the Blood Guardian.
And the only time that the Blood Guardian has ever come out of Lucifer's body is when Lucifer has clashed against other Hell Gods and Heaven Gods.
After all, who would be strong enough to make Lucifer almost lose his life other than his fellow Gods?
No one. And that is why Blood Guardian thought that there is a God near here, who was just battling Lucifer.
