Lin Zhou, a delivery boy who makes a living in the steel forest of the city, is used to traveling at the fastest speed and with the lowest posture. Until that rainy night, a strange order led him into a wealthy mansion, and he accidentally uncovered a fatal secret. When the cold blade touched his throat, when the powerful eyes looked at him like an ant, Lin Zhou's choice was not to kneel down and beg for mercy, but to use all his scheming and ruthlessness honed from the bottom to turn the muddy water upside down. You regard me as a piece of grass, and I will let you know that even a piece of grass can cut the emperor's hand.
