These thunder element spells ranged from cantrips to third-circle spells. The first one was a fourth-circle spell.
This spell should have been from a wizard from the Thunder Dragon family, but Levi had forgotten who it was.
This was one of the few fourth-circle lightning techniques he had. After cultivating it, his body turned into a lightning afterimage and his speed was not bad.
"I'll use Thunder Afterimage as a spell model to break through the fourth-circle."
A fourth-circle spell model was far more complicated and sophisticated than a third-circle spell model.
However, Levi felt that it was not much more complicated than his third-circle innate spell.
After choosing the advanced spell, Levi took out the Blood Demon Meteorite Iron that he had obtained from the auction.
