"The forbidden spell that is enough to destroy a city has also appeared. Do you know how many magic elements it needs to activate? Maybe what I said is not accurate, but there is a rough division. The level-4 magic needs about three hundred magic elements, and the level-5 magic needs six hundred magic elements!" "The level-6 magic needs about one thousand and five hundred magic elements, the level-7 magic needs about three thousand magic elements, and the so-called level-8 magic requires at least eight thousand magic elements!" "Now you can also see the effect of eight thousand magic elements. If the opponent's spear hit the open space, it would be enough to destroy a small square. As for the level-10 forbidden spell, although I don't know the specific situation, I have heard that the lowest level of the single forbidden magic should be one hundred thousand magic elements!" Speaking of this, Uncle Lie sighed slightly.
