The so-called cross-dimension camera, on the surface, looked the same as a normal camera, but when you played the video that was taken by it on the computer, it would only show the animated sceneries, and it was the special 3D version. It was just like those Hollywood blockbusters, you know it was animated sceneries, but it looked very realistic.
Those invisible mini Villagers, as well as those small beasts that normally people would not be able to see, would be shown in the video that was taken by this camera. However, there was a problem. This cross-dimension camera could recognize its owner. So only Zhou Yu could use it. If other people used it, it would only work like a normal camera.
