Although it was a convenient spell, it wasn't something easy to put into practice. First of all, even though Leon would be able to use it to cross larger distances when he levels up the skill, at level one, he would have to spend almost half of his mana to travel between two places that were one kilometer of distance from each other. Besides, he would have to use one thousand points of mana to create the 'checkpoints,' and the checkpoints had to have some gravures and that gravures had to be made of mana.
"It is a very complicated spell… I have no idea how the researchers discovered that." The girl said. " Can you memorize the gravures?"
"No, but I already learned the logic behind it, so eventually, I will discover the right patterns of the gravures," Leon answered. "Now, where are the archives about time-magic?"
