The spell itself has the function of concentrating light, and after reaching a certain level, it should be able to adjust the light.
By adjusting the light through this spell, more light can be concentrated through a convex lens, thus gathering more images.
The gathered light reaches the concave lens on this side and can be dispersed again.
By then, using the Reflection Skill, the light that has been dispersed can be imaged again, and one should be able to observe the scenery of a farther place.
Fang Yun is not sure whether this will enable observation of places a thousand miles away.
But it seems there is still some hope.
Besides this method, he can't think of any other way for now.
After confirming this rudimentary plan, Fang Yun begins the experimental process of the spell.
First, he stops the flow of Mana within his body.
