I'm the Only One in the World Who Can See Ghosts

At first, no one believed that Ji Erlang could see ghosts, not even the dead. Corpse: I’m lying in these seventeen places, quietly watching you do your thing. The killer was caught red-handed, but the interrogation ran into a few problems. “So you’re saying you have Yin-Yang Eyes?” “Yes. I saw the victim’s ghost. He asked me to help dispose of the bodies.” “Why didn’t you call the police? Instead, you dug the bodies up from seventeen different places and buried them all in one place?” “Because he didn’t want you to catch the killer. He also said he’d teach me how to trade stocks and make me a stock-market god.” “Why didn’t he want us to catch the killer?” “I have the right to remain silent.” The police officer glanced at the psychiatric evaluation. “What about the stock trading? We found that you haven’t bought any stocks.” “I didn’t like the stocks he recommended.” “Hmm?” “They were all red, like blood. It was scary to look at.” “...And you weren’t scared while digging up and burying the bodies?” Ji Erlang smiled. “He was dead. There was no blood.”
