Li Yan licked his dry, cracked lips, momentarily at a loss whether to advance or retreat.
He had made his way here step by step, drawn by the sound of gunfire and roars, arriving just in time to witness a roaring shot beneath the sandstorm, blasting away a significant portion of the terrifying monster's skull.
Initially, Li Yan thought it was one of the zombies possessing a sniper rifle, which, given what he had seen along the way, wasn't impossible. But the second loud gunshot made Li Yan realize he was wrong.
The second roar, amid the thronging horde of zombies, cleanly burst the zombie leader's head, plunging all the remaining zombies into temporary madness.
Whether it was the genetically collapsed bio-monsters or the ugly zombies belted with grenades and wielding submachine guns, none understood the principle of "the mantis stalks the cicada, unaware of the oriole behind." They attributed all casualties to the other party.
