Teleportation divine art was actually a divine art constructed by algebra. The difference in direction, place, distance, and space needed one to calculate the order and rules of the runes.
Every established teleportation point required a huge amount of mathematical operation.
Two words mathematical operation, what was the operation?
Operation meant the sequence, evolution, change, rules of the rune formation. With evolution in the sequence of the rune formation to change the rules, only then could he have a calculation.
By refining the teleportation divine art into a treasure, it was to rely on the runes and formation changes imprinted on the treasure to push the calculation, which was thousands of times more complicated than using the beads of an abacus. It could be seen as a large-scaled abacus that was strangely constructed.
