The afterglow of the setting sun shone on North River Pass's city walls. North River Pass was silent. Many weeds in the city were gently swaying in the breeze.
At North River Pass's inner city pass, the World Entrance—which was about a kilometer long and a quarter-kilometer wide—remained calm. Suddenly, without any warning, dozens of demon monarchs rushed out. All of them were extremely vigilant as they tried their best not to make a sound. Most of these demon monarchs were at the second Firmament. Only seven were third Firmament demon monarchs.
A goat demon monarch stood at the exit and looked in all directions. He waved his hand slightly, and demon monarchs immediately surged out from the World Entrance.
The demon monarchs entered the human world en masse.
