It took a while for the support team to get used to that scene, where Ethan disappeared for an instant, and then a massive impact happened in the middle of the zombies' army, but eventually, they began to offer real support to Ethan. Since there were so many of them, all what Ethan needed was a few seconds to recover and then be ready to launch another attack. Much to Ethan's surprise, it took him a while to feel the mana entering the army, his senses weren't that sharp anymore, so it was only natural. Still, he discovered that the mana was coming from the North.
"I wonder what is North from here… the frontlines are supposed to be on the West, but I guess hiding in an unexpected place is the obvious thing to do."
