The Apocalypse Is Coming, I Actually Farm and Upgrade to Fight Zombies

Ding! Binding completed! Congratulations to the host for binding to fight zombies and upgrade the system! "What! What the hell is upgrading from fighting zombies!?" Ling Zhilin was an ordinary homeless man, relying on his family to support himself. One day, while he was frying bacon at home, he suddenly heard a noise coming from the balcony. When I walked over, I discovered that it was actually a zombie! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
