Jinyi Tianxia, ​​I Have a System

I am a royal guard, but the golden finger system forces me to do tasks. No prisoner in the world can escape my pursuit, because I have a golden finger. The King of Hell said that you would die at the third watch, but he would never let you live until the fourth watch; I, Yang Xiao, said you can't escape tomorrow, so I will arrest you and put you in jail today. The emperor said: "The Yang Qing family is indeed my Dinghai Shenzhen!" The governor of the East and West factories said fearfully: "In the future, be careful not to offend Yang Yan Wang." The commander of the Jinyiwei said with satisfaction: "What I, the Jinyiwei, can't do in the future can be done." The chief catcher of the Six Doors said worriedly: "Sir, Yang Xiao has robbed our case again."
