After coming back from the surprise of those golems suddenly appearing like this, Klein quickly gave the order to attack.
The wyverns stopped using their breaths on the rest of the undead horde and started focusing the firepower on the golems.
It was just that these flame breaths never reached the golems.
Before they could reach them, there was more movement from the undead horde.
Just like a few days ago, the undead started gathering together in one mass. Only this time, they didn't come together in the form of a hand.
This time, they formed a wall over the golems that were at the wall.
These were walls that completely blocked the flame breaths that fell down at the golems. With how thick the walls were, not a single bit of the flames reached the golems in the end.
It seemed that the lich didn't care about the undead at all, as long as these golems were safe.
