Hard to kill

"This is a fine sword," Hephaestus said. "Where did you get it? This type of Enchantment is quite rare."

 Ryan couldn't help but feel that he was being mocked. A sword almost pierced Hephaestus' heart, and he was asking who forged the weapon… Regardless, it was time for plan B… it was time to formulate plan B. Fortunately, the next plan was formulated pretty fast. If Hephaestus needed that heat to make his body stronger, Ryan knew the place where he wouldn't be able to keep that spell active… without paying a high price.

 Ryan teleported to high in the sky and then eventually, to space. Hephaestus followed him as if that wasn't a real problem. In the end, the heat followed him. Apparently, it was an advanced spell that created a barrier, and the interior created a perfect environment for Hephaestus. Still, how much mana did he have to do that?

"You sure have a lot of mana," Ryan said.
