With the help of the system, the Zhao family's life is getting better and better. The birds were jealous and began to spread rumors and slander everywhere. Jia and Zhang are spreading rumors and am I speculating? No one dares to care. Jia Dongxu spreads rumors that I am an enemy agent? Should I send you to prison as an enemy agent first? Oh? Isn't Silly Pillar an enemy agent? Then let him become an enemy agent. You are not strong-willed, do you blame me? Qin Huairu wants to play a honey trap? ​This... Think about it. Rebirth, undercover agents fight against the sky and the earth, and live a wonderful life!
