My Backyard Leads Directly to Yin and Yang

When I was sorting through my grandfather's belongings, I found a land deed with strange material and illegible text under my pillow. On the first seven nights, my grandfather's spirit returned without touching the ground and told me that the land deed had "recognized me". It turns out that Grandpa saved a mysterious beggar back then and got this land deed - it controls a secret passage connecting the Yin and Yang worlds. Any spirit that wants to pass must pay a "toll". After grandpa explained, he smiled and set foot on that road. That was the first person I "crossed". Since then, my backyard has become the only back-door toll station in the three realms. The price is clearly marked, no one is fooled, and it is designed to provide a "fast track" for all kinds of souls. I have seen all kinds of "clients": a billionaire coal boss who disliked waiting in line for too long at the gate of hell, so he used his evil deeds to buy the most expensive channel; an official who has been greedy all his life, still wants to stuff red envelopes and jump in the queue after death; a vixen who has been practicing for a hundred years, never forgets to ask for invoices and go back for reimbursement; the infatuated groom who died at the wedding, pledged all his wealth just to be reincarnated faster and find his lover in the next life. Of course, there are also those who try to force their way into the Overlord Dinner, but the end is often worse than they imagine. After working in this business for a long time, I have realized a truth: some debts must be paid even after death. Here, if the money is in place, everything can be said; if the money is not in place, there is nothing to say. I have the final say on this road. What you owe me will have to be paid back in the next life.
