BANG!

The halves of the key slammed together, and suddenly Leonel felt as though the world had been enveloped in a seal.

He was taken aback for a moment before his eyes blazed with realization. This was… truly too convenient.

This key couldn't be considered to be a God Armament. A God Armament was not only a classification of powerful weapons but also a sub-class of treasures that allowed themselves to fuse with flesh and blood.

Of course, The Hourglass was also capable of this. It was just that El'Rion hadn't reached this step yet, and it was also quite dangerous to form such synergy with it.

But that was also why it had the weight of a world in Leonel's hands, but had been as light as a feather in El'Rion's.
