Wang Tao watched the surging tide of zombies, his heart unmoved.
"Still not coming out, huh..."
He was waiting for the appearance of a Level 4, Lord Zombie, but those several Level 4 Zombies seemed to be planning to use Ordinary Zombies to wear down the base first, as they themselves had not shown up the entire time.
Wang Tao wasn't naïve enough to think that those four Level 4 Zombies had left; they were definitely hiding somewhere!
After waiting a while longer and seeing that the Level 4, Lord Zombie still wasn't showing up, Wang Tao took out an anti-materiel sniper rifle.
Aiming, he squeezed the trigger.
Bang!
An Ordinary Level 3 Zombie's head exploded.
This rifle was powerful, capable of killing an Ordinary Zombie with a single shot.
Since the Level 4 Zombies were not showing up, Wang Tao couldn't just wait idly; he started killing other zombies to relieve some of the pressure on everyone else.
