"But I wonder why the murderer is in an octagonal shape. According to Feng Shui, this should be unlucky, after all, all the way out is blocked by people with blood. Mo Mo said with a frown.

"Why is this related to feng shui again?" The director was puzzled.

"Oh, think about it, if the murderer really kills another person at this point according to my reasoning, it will be an octagon, and the ancient street will be impassable, which is equivalent to a circle of corpses around your body, so that you can't escape from this place, if a dead person represents a guard, it is to keep this street under strict guard, and destroy Feng Shui, which is a great omen." Mo Mo said with an unfathomable face, in fact, she doesn't know much about feng shui and the like, but she just knows a little, besides, is it still a good sign that there are a bunch of dead bodies around you?

"Oh." The director said that he was embarrassed, this person who came out of the elite army is different.

"So I'm wondering if this murderer has a bit of a holiday with the ancient street? Maybe it's someone here or somewhere. Mo Mo touched her chin and said carefully.

"Yes, I think that's the case." Ye Xuantian took over the words.

"So, if we want to find the murderer, we have to go to this ancient street."

"That's right, Director, how long has it been since your cases occurred?"

"This, there is no pattern, sometimes 3 days, sometimes 1 day 2." The Director replied.

"That's the case, then we have to start an ambush tonight, that's what I said about the local director to bring people to watch, don't startle the snakes, let those policemen put on makeup and don't be recognized, don't be too many people, after all, there are sparsely populated there, and adding so many people at once will cause suspicion." Mo Mo instructed.

"Okay, I see." The Director nodded.

"Let's go, every day." Mo Mo took Ye Xuantian's hand and went to the ancient street.

"There's nothing in this place, it's just that there are fewer people, it's a little barren, and the rest is fine." Mo Mo dragged Ye Xuantian for a walk on the ancient street.

"I think so too, but according to what Mo Mo said, why did the murderer fence off the ancient streets? If you have a grudge against someone, it's good to go straight to that person, so why bother. Ye Xuantian grabbed Mo Mo's hand with his backhand and said.

"Yes, but how do we know the murderer's thoughts? Maybe he's got something wrong with his head. Mo Mo replied nonchalantly.

"Let's go, you won't find anything by walking like this, so it's better to go door to door and ask." Mo Mo and Ye Xuantian came to the door of a house.

"Knock knock." The sound of a knock on the door remembers.

"Is anyone home, please?" Mo Mo asked loudly.

"Here we are." The door was opened, and out came an old lady, who was already very old.

"Hello grandma, we want to ask you something, so that we can go in and talk?" Mo Mo asked politely.

"Oh, come in."
