The origin of all things, the beginning of life. I am the only one who is supreme among all creatures in the world. All the heavens and worlds are shocked. With the system in hand, I own the world. 111111111 Pre-viewing reminder: emotional aspects of the plot The first part is about the city, and the second half is about all the worlds, and there are more than one plane.
