The ability to cover a distance of 51,214 light-years in 7 days, 7 hours, and 12 minutes can only be considered very fast. In fact, he believes that it should be considered absurdly fast. After all, this is a speed that appears to be faster than light.
However, he doesn't think he was able to achieve this because he can actually move faster than light. He is sure that he could only achieve this by traveling in the third dimension rather than moving through the first.
In the third dimension, distance has shrunk. Reality looks like a map in the third dimension, so by moving a short distance on the map in the third dimension, he can move a much greater distance through the first dimension.
According to his experience, the usual rate of travel in the third dimension is one day to cover one light year for every one unit of divine power from the Cave Heaven.
