Be the Master of Change

Is it time travel? It's still a game world, but there are good things everywhere. Why don't I have a system? Please give me a system! There are Yuan Tong's "Xiling Empire" and "Abnormal Creatures" as the background, as well as the real world of the earth. Of course, as a first-person work, it is generally not as long as "Xiling Empire". I estimate that there will be about 200 chapters. Any more will be nonsense. . . Hahaha!
