After Hanging up for Five Hundred Years, I Turned into a Demon?

The void plane descended into the world, the outer and inner planes were divided above the blue star, and the void beast descended into the world, beginning the era of spiritual energy recovery. Lu Xuan accidentally awakened the on-hook upgrade system. When the computer is idle, it is managed by the system. It is simple, efficient and safe, so Lu Xuan took a good nap. But who knew that this sleep would last for five hundred years, and he would not wake up until the system disappeared. However, when he woke up that day, he discovered that the system had prepared countless surprises for him over the past five hundred years. "What! Did I kill the gods of the void five hundred years ago?" "What! I started the Doomsday Era four hundred years ago with my own hands?" "What! You said that the starry beast in the universe, which is about the same size as the sun, is my pet?" "What! The system actually found me eight wives without authorization, and all of them are peerless empresses?" Lu Xuan: "Holy crap, how many surprises does this system have prepared for labor and management!" This novel and its characters are purely fictitious.
