The moment he heard the World Manager's words, the Demon Emperor realized he had made trouble.
He had wanted to stop right then. He could afford to offend others, but the World Manager was someone he truly knew nothing about.
Unfortunately, he reacted too slowly and ended up locked in a dark cell.
There, he truly experienced what absolute darkness meant.
Neither the Demon Emperor's demon fire nor anything else could illuminate the place.

Whenever he tried to enter dormancy, a force would wake him.
Just like that, a long time passed without his knowing.
When he emerged again, half a year had already passed.
Less than a month remained before the Gate World War.
Over that month, he finished forging the Heaven Measuring Ruler and reorganized the Primordial World's armies.
Meanwhile, the Demon God Pavilion began spreading throughout the Primordial World.
Countless members of the Mechanical Race left the Demon Realm and began diligently farming in the Primordial World.
The various mines were also filled with members of the Mechanical Race.
This race had very few actual members.
They created ordinary robots, one after another, to work in their stead.
The Primordial World's rate of resource extraction improved significantly.
An endless stream of resources was extracted and put to use in every corner
