Warning: This story has an Evil MC.
No need for moral justification, and the MC is very OP and Malicious. 
Readers have been warned.

Endless Entity, The Devourer of Existence,
That was the name and title they gave me...
and my task? To devour the world.
Centuries has passed since that bastard transmigrated hero defeated me, and now it is my time to fulfil my duty as the God of the End once more.

But to achieve my goal, I have to awaken all the lesser gods and devour them first to restore my full power.

And I shall do that, mercilessly.

PS: The story starts out slow, but it will be clearer after first ten chapters.
