Traveling Through 60 With Space As A Security Guard

Who am I? Where am I? I am a time traveler, and so am I. I am a time traveler who can defeat the sky, the earth, and the air in seconds. I have everything I want when I travel here. I don’t have anything I want, and I can’t even have enough to eat. I am only sixteen years old, but I have a physique of thirteen or fourteen. I can be blown away by a gust of wind. What about my system? Isn’t it a standard system?
