The apocalypse erupted. Plants and animals mutated, and zombies ran rampant. Fang Yuan unexpectedly obtained a "Builder System."
But this System could only build houses and carry out construction. It had no combat ability whatsoever and was utterly useless in a fight.
Fang Yuan unexpectedly discovered a major bug in the System: fence posts, concrete walls, even entire cities could all become weapons for him to instantly kill zombies and fight monsters.
From then on, with the "Builder System," Fang Yuan could defend and attack. With powerful defenses and devastating offense, he slaughtered his way across the battlefield and became the king of the apocalypse.
