Chapter 42: Helping
As Selena saw that Lux frowned, she giggled for a moment before her expression suddenly turned serious.
"Don't leave Earth for one year."
BOOM!
It was like a bomb exploded inside Lux's head, and honestly, this was the last thing he wanted to hear right now.
Because if the demons ended their alliance right now, it would also mean that he couldn't take his sisters and the others to leave Earth.
Since his plans of leaving actually revolved around the demon race...
"What do you mean by that? Why should I stay here for longer than necessary?" Lux quickly asked. He needed to find out what happened that changed Lucifer's mind.
"We have been honest with you since the beginning, right? So listen to me now. If you use our Veil of Worlds to leave Earth, our past enemies would be aware of that."
"It's something Dad recently discovered as he began to recover more of his powers."
CREATORS' THOUGHTS 
Zefyr
Zefyr Basically: Humans+Angel Bloodline+Demonic Powers=Humans of today, but with the Lock of Heavens restraining them.
Reading once again, you should understand where the abilities came now and whatnot.
I won't say anything else other than ask you something: why did the Lock of Heavens begin to weaken so suddenly? *Author is grinning behind the screen*
Enjoy.
