Weird Dark Energy

"Attack! Hold on!" Dan Hen shouted beneath the defense platform. The submachine gun he was holding continued to fire shots at the zombie horde around 30 to 40 meters in front of them, which were starting to surround them.

"Ta, ta, ta..."

"Boom!"

Ion Flame and Alarm, as well as one of the other Fire Manipulator; the three long-range professions' energy converters continued to cause flashes of light as skills were released.

Fireball, Earth Spike, Fire Wall, Sea of Fire...

Multiple single target or crowd damage energy skills were thrown at the zombie horde, turning the area in front of the horde into a sea of fire, which delayed their advance.

This was especially true for the Earth Manipulator's Petrifaction Zone. It caused the earth energy in an area in front of the group to sink, making it look like the zombie horde had walked into a swamp or quicksand, and in an instant, they were significantly slowed down.
