The rich and powerful spend a lot of money to obtain orders for evil deeds, which will deduct their life expectancy and trigger social death penalties. Villains who bully the bottom and blaspheme the souls of the dead will automatically suffer the backlash of cause and effect, and the whole process is matched with a poisonous tongue system to make fun of each other. The protagonist pays off debts by taking orders and treats seriously ill parents, while fighting against the black-hearted real estate capital that squeezes the people. Finally, he unlocks the ultimate power of cause and effect, liquidates all evil-doing powerful people, and controls the justice of good and evil in the city.
