Night Talk in the Paper Shop

Night talk in the paper shop I run the only paper-making shop in the city, help people tie up villa beauties, and occasionally check out Feng Shui. Until that day when I got on the No. 13 Bus, the old man in the seat next to me suddenly turned his head: "Can you see me too?" Before I could say anything, a total of 12 people in the car turned around. What's even weirder is that after three stops, the bus reached the end, and 11 passengers disappeared out of thin air, leaving only a body on the seat. The police believed that I was the one who killed him - after all, I was the only living person in the car. In order to clear the suspicion, I can only use the yin and yang eyes and paper pricking skills to solve the cases that they can't see.
