Job Transfer for All: the Weakest Poisonous Milk? Have You Ever Heard of Wu Zu?

When I woke up, I was transported to a world where everyone changed jobs. The strong will rule forever. The weak beg for mercy. At the age of sixteen, Yang Chen changed his profession to become a poisonous nanny, a profession that was rated as one star and had no development prospects. But the strongest witch ancestor system was bound, and from then on Yang Chen embarked on a heaven-defying and extraordinary path. "Oh my god, why is his poison so powerful? Even star-level poisonous scorpions were poisoned to death!" "If a death blessing continues, the living will die, and the dead will come to life!" "You told me this is poisonous milk? This is Hades!" "..." When thousands of races were attacking the city and human society was in danger, the figure that looked like a god descending from heaven appeared in front of everyone. "Everyone in the world says that poisonous milk is the weakest profession, but have you ever heard of the witch ancestor who was reborn with blood and devoured the world?"
