Even though Henrik's fireball didn't seem threatening in the least, the few zerglings that received it instantly exploded; flames tore out in all directions, lighting up the entire oil field. The flames surged across both sides like a tidal wave, forming into an impressive firewall, fire blazing as it released spirals of thick fumes. The zerglings at the back either had to continue advancing and dive through this sea of flames, or make a huge detour to the sides. This undoubtedly provided much buffer time to the entire party.
Yet the sheer quantity of zerglings was uncountable, so much that it could neglect any form of barriers!
Over the sea of flames, zerglings repeatedly replaced their fallen comrades as they sacrificed their roasted bodies. If one had to describe this advancing wave of beasts, it was like an arachnid tide!
A tidal wave but with repugnant bugs!
That short hundred metres of escape route, had now turned into a bitter struggle against death!
