Bind the Zombie Cultivation System to Satisfy Hunger by Catching Human Traffickers

Gu Yan, a cattle and horse social animal who worked overtime and died, was selected by the system to become a zombie. In order to survive, he had to drink blood to survive. The evolution point of chicken and duck blood was too low, so he had an idea... Since then, human traffickers, murderers, and fraudsters have all been listed on Gu Yan's menu. He can feed himself to increase his evolution points, and eliminate harm for the people, killing two birds with one stone.
