Heath transmigrated to an alternate dimension and awakened the [God-like Extraction System]. With the help of the system, he steadily walked the path of the Witcher to become a god.

Year 2056, in a city in the Yuan Jiang Su Jin area. On top of a ruined, shattered six story residential apartment sits a teenager wearing a combat vest, militaristic trousers, and alloyed battle boots. On his back is a hexagonal shield and equipped is a blood-shadow battle knife. He sits there silently on the edge of the roof. At this time, the sparkling sky was shining and there was a refreshing breath within the air that blew towards him. However, there was only silence within the ruined, deserted city, with an occasional howl that makes your heart skip a beat.

He said no!” The next morning, the headlines of the Sanjiang Apocalypse Morning Post read: Zhang’s Group Chairman, Zhang Ye, not only admitted to making zombies work overtime, but he also abused a zombie in front of reporters, truly a man without conscience! Our newspaper expresses strong disdain for such a person! This book is also called “Who Let You Bring Zombies into the Factory”
