The giant crabs crashed into them.
The first thing Isaac instructed his men was to defend. Most of his members were not ready to fight the crab monsters, he could see it from the tense looks on their faces.
A similar scene was also shown by the Golden Dragon members.
They didn't seem to be fighting as aggressively as usual. Their fighting style tended to be passive, the melee fighters kept guarding the front lines, while the casters and marksmen launched attacks from behind.
Isaac was impressed with Ling Tian. He felt that man's decision was right.
These giant crabs had hard shells. Physical attacks wouldn't work against them. It would take fire and lightning magic that could at least cause them significant damage. However, with watery terrain like the swamp, both magic elements were ineffective. Especially the lightning elemental magic. It could harm the people around.
