Ethan was confident in his plan, and after thinking for a while, even Hannah began to feel confident. That was right. There was a huge flaw in the necromancer's strategy. He had to use mana to revive the zombies, his mana would have to fly from wherever he was to the battlefield, and the mana would revive the corpses. Any mage with good senses would be able to tell the direction the mana would come from. However, few mages could approach the horde of monsters for more than a few moments without getting themselves killed. Hannah was one of them, but since her teleportation required some preparation and concentration, it wasn't something she could do.
"I got the gist of your plan, but that will only show us the right direction and not the exact position of the necromancer," Hannah crossed her arms and spoke.
"That is more than enough," Ethan shrugged. "With your power and my skills, we can find him before he realizes that we are planning something."
