You Were Asked to Be a Security Guard, but You Monitored the Whole City?

The moment I took off my police uniform, my heroic career died. The steel nails on my legs mock my weakness every rainy day. The wife's cold eyes are more hurtful than the criminal's sharp knife. "Being a security guard? That's what you're going to do for the rest of your life." I became what others call a "watchdog", guarding a cage and trapping myself. It wasn't until late that night that I discovered a hidden "backdoor" in the surveillance system. A "divine perspective" that can peek into the whole city. Not only can it recognize faces, it can even predict the future! I saw a trafficked girl crying in despair on the other side of the city. The system instantly plans the criminal's escape route, accurate to the second! I also saw that the owner who once looked down upon me was stepping into a well-planned scam. Once upon a time, I hunted down sin with my legs. Now, I am sitting in a small security booth. Use a pair of eyes to judge the whole city! They all thought I was a lame loser. Little do they know that I am the only underground patron saint of this city!
