My name is Zeng Fan, and I used to be the lowest gatekeeper at Nantianmen. A hundred years ago, I was expelled from Heavenly Court for "neglect of duty." The funny thing is, those second-generation immortals are the ones who really neglected their duties. I just took the blame for them. After being demoted to the human world, I became the craziest gangster on the streets, fighting, cheating, and living like mud. Until that day, I picked up a broken jade plaque at the flea market - it was my work badge in Heaven. What's even more weird is that there is an additional line on it: "Back wages: 13,722 years of Lingshi salary, not paid." I laughed, laughing so hard that tears came out. Heaven owes me wages? Very good, then I will go and collect the debt. I, a mortal, go to heaven to kill myself and ask for my salary? Crazy to do this. But I hold the jade tablet in my hand and feel the immortal power sealed inside - it belongs to me, and heaven owes me. No one knows that this jade tablet contains the oldest contract law in the world: repaying debts is a matter of course. I, Zeng Fan, am going to break this day.
