Mountain Breaker Axe was surprised. Even though he was no expert when it came to MMOs, he at least had a good idea of the most basic spell attributes, the calculation of damage, and other such matters. Gu Fei was not wrong that, for a Fighter to withstand two of his Twin Incineration, he of course needed fire resistant gear, but Gu Fei had changed to using Lightning spells, so fire resistance would be completely useless.
With a flip of his right hand, Moonlit Nightfalls was back in his hand once more. Even though Palm of Thunder required Gu Fei to have an empty hand to be unleashed, he still needed to have an equipment to raise the damage of his spell. Gu Fei made a feint with his sword, and Mountain Breaker Axe, who had indeed not studied anything related to blades like what he had claimed, was completely unable to see through the feint, and very conscientiously focused on dodging the attack.
