"Xu Xin! The explosive projectiles are almost running out!" Lou Fei'Er operated the control panel, a bead of sweat trickling down her forehead, and shouted to Xu Xin.
Xu Xin immediately reloaded both of the crossbows with explosive projectiles. The explosive projectiles in his hand were virtually inexhaustible.
Under the combined assault of the explosive projectiles and the plant heart, hundreds of mutated creatures were slain, but only a small portion of the mutant army was depleted.
Moreover, they seemed to have found a way to evade the explosive projectile damage. Although Lou Fei'Er's hand speed hadn't slowed, and the number of explosive projectiles shot increased, the frequency of alerts in Xu Xin's ears actually decreased.
The plant heart's defensive line began pushing back slowly.
Ninety meters, eighty meters, seventy meters...
"They're getting closer! What should we do!" Lou Fei'Er exclaimed anxiously.
"Do what you need to do, I'll handle the rest."
