The Demon Lord paid no mind to Zhang Menglong's outrageous words, because in his eyes, every creature in this world was a lowly being, much like a tiger wouldn't get angry at an ant for shouting at it.
As Zhang Menglong had guessed, this door leading to the human world and the demon world was not man-made, but had existed since the birth of this world.
However, this door was always in a sealed state, and no one knew how to open it.
In the demon world, the Demon Lord wasn't born into power.
The demon world is a mirror world more advanced than the Main World, where life has existed far longer than the Cang Yuan Era and this current age combined, which made the World Force much stronger, the world's stability higher, and the life forms born there much more powerful.
Throughout the history of the demon world, there have only been seven Demon Lords, and the path to becoming a Demon Lord is singular: kill the old Demon Lord to become the new one.
