The Demon General accepted the order and selected a quick-flying demon to deliver the Demon Emperor's command to the Human World.
Originally, this Demon General intended to send it to the Monkey Demons' territory, as it's closer. However, after a subordinate mentioned that the war might hinder the delivery, he changed his mind and directed the demon to send the command to the Human World.
The location of the Human World is not a secret within the Endless Star Sea, and the Demons, who occupy a large star domain near its center, aren't far from the Human World.
Moreover, this demon was indeed very fast, so by early the next day, the Human World received the message from the Demon Emperor.
Zhang Kailei, stationed in the Human World, contacted Bai Yan through the demon contract and relayed the Demon Emperor's message to him.
"The Demon Emperor wants us to return all Monkey Demon prisoners to the Demons. What do you think?"
