Death

"Demon Eyes, activate!" Lucifer shouted out loud and as soon as he did, the Demon Eyes did its work.

Of course, all Lucifer really did was just to look at the darkness surrounding him.

It was quite weird that he was looking at it even though he literally got no eyes right now, but that was just how it is.

That was just how Lucifer's demon eyes worked.

And as soon as Lucifer looked at the darkness surrounding him, the Hell Gates and the Great Seals...they...just disappeared as if a gentle wind blew over them.

Of course, this was the power of Lucifer's Demon Eyes, and it was really amazing how it was able to make the Hell Gates and the Great Seals disappear just like that.

However, even though it looks so simple on the outside, it was actually not.

What the Demon Eyes did in order to make the Hell Gates and the Great Seals disappear was to cut off the mana connection that they had with the Patriarch, the source of their mana.
