Ouyang Fan took a taxi and came to Guangming Street. Guangming Street is full of old buildings, and there are small asphalt roads between the buildings, but there are no street lights. At this time, the lights of the buildings were shining, reflecting the road. Ouyang Fan got out of the taxi in front of Building No. 1 outside the building group and walked to the third building behind. When he got closer, he suddenly stopped. He noticed a man standing against the wall at the dark head of Building 3.

"Who?" Ouyang Fan let out a low snort.

It's purely a subconscious shouting out of nervousness. But the man was silent, and quickly left the building, turning to the other side.

Ouyang Fan wondered in his heart: Who is this, is it a thief or something?

Ouyang Fan is not a coward. Don't look at the school all the time, but he is usually very bold, and once spent time in the wards of the most aggressive and seriously mentally ill patients to test those special psychology. He also once spent a night in the wild graves, accompanied by ghost fire and boundless silence, to observe people's psychological adaptability.

At this time, he quickly rushed towards the corner of the building where the man had disappeared just now. But when I got there, the night was dark, the lights were dim, everything seemed to be shrouded in a fog, and no one was seen again.

It's weird!

He had to turn around, cross the building, and come to the front of the building, and found that his white car was parked in the empty field under the bright lights of the building. Could it be that the man just now was peeping and stalking? Who is this?

Ouyang Fan came to the car, opened the door of the passenger seat, and sat in. Liu Lin sat in the driver's seat. In the back seat, Ning Baolan and Jiang Ruhui sat side by side. Ning Baolan was in tears, and Jiang Ruhui grabbed her shoulder as if she was comforting.

"Dr. Ouyang, I'm smiling at you." Ning Baolan let out a long breath.

"What's going on?" Ouyang Fan was puzzled.

Liu Lin explained: "Brother Ouyang, Teacher Ning said just now that her ex-husband, that is, Naqigu, has changed his temperament greatly in recent years, and he has become obsessed with some crooked things. It is likely that he has something to do with the murder of Han Na's family. ”

"Huh?" Ouyang Fan was shocked. "Tell me, what's going on?"

Ning Baolan's tears couldn't stop flowing, and she said: "I don't know what's wrong with Qigu, the last few times we met, he was always gloomy and cold, and he said something inexplicable from time to time. He collected a few things, all murderous, perverted, broken human limbs, etc. Alas! Maybe I shouldn't have divorced him in the first place. ”

No one knows why they divorced. But listening to Ning Baolan's tone now, there may be a lot of 'hidden secrets' in it.

Ouyang Fan pondered for a while and said, "We can't conclude that there is something wrong with Naqi Gu based on speculation, so we can report the case to the police, right?" Since everyone is here, why don't you meet Na Qigu and see what he is tinkering with? ”

"Good!" Jiang Ruhui was the first to agree, and everyone had no opinion.

Get out of the car together and go upstairs. On the right side of the third floor is the rented house in Naqi Valley.

Ning Baolan knocked on the door, and Naqigu came out. It was a stocky man of nearly forty years, dressed in the clothes of an ancient alchemist, with a tall square hat and a ponytail duster in his right hand. Jiang Ruhui was frightened by his outfit and let out a low snort.

Naqigu's face was gloomy, and when he saw four people, including his ex-wife, he was not surprised, and silently let everyone into the house. Then, without squeaking, he went out of the living room, entered the big house, stood in front of a statue of Zhang Tianshi by the south wall, closed his eyes, muttered in his mouth, and ignored the guests.

Everyone frowned and sat down on the sofa in front of the coffee table. There is a picture on the coffee table, and the words written above the picture: "Yin and Yang Numerology Chart".

"What's the yin and yang numerology diagram?" Jiang Ruhui said in surprise.

Nachigu ignored it, still chanting the incantation.

Everyone looked carefully, and saw that the chart was boxy, and the diagonal lines inside formed a big cross, and the four corners of the chart were marked with the letters "A, B, C, D". In the middle of the picture, it is blacked out again, and the words "Dark Kingdom" appear in the black, which seems to be mysterious. Ouyang Fan has read a lot of such books, and he can't help but laugh in his heart. He remembered that there seemed to be a detective novel called "Numerology Puzzle", so Qigu learned it from people, right?

Ning Baolan whispered, "You understand, right? In fact, he majored in finance in college, but now he is obsessed with feng shui gossip, divination and the like, and he will tinker with these when he gets home from work at night. There were a lot of these books in the bookcases that filled the room. ”

"Hey! Old man," Ouyang Fan said with a grin. Only then did Liu Lin and Jiang Ruhui know that he knew Naqi Valley. "We're four people here, and you don't receive it, what do you mean?"

"Wait, wait, right away." Naqi Gutou didn't turn around, only facing Zhang Tianshi, and let out words.

"Alas!" Ning Baolan sighed and whispered, "This strange valley is really incorrigible. Half a month ago, he fell in love with a girlfriend named Wang Dong, who was only twenty-five or sixteen years old, and he was actually like him, obsessed with fortune telling and feng shui. At night, she came here, and the two performed gossip and analyzed strange pictures, which was really in love. ”

Nachigu finally stopped chanting the mantra, went to the coffee table, and sat down. He squinted at Ouyang Fan, with a look of disdain on his face: "I can't understand this picture, right?" Let me tell you, the secret of heaven must not be revealed. ”

Introducing Liu Lin and Jiang Ruhui to him, he only nodded.

Ouyang Fan smiled: "What heavenly opportunity can't be leaked?" Ouyang Fan decided to go straight to the point, "Qigu, we are here today to crusade against you." Why did you go to the north of the boss of Changhe Group to observe? ”

"What are you talking about?" Nachigu's eyes widened.

Ouyang Fan was still laughing: "You don't understand? ”

Ning Baolan pulled him: "Really, Qigu, you tell us the truth. They all saw you outside the north wall of the boss of the Changhe Group tonight. And Han Na, the daughter of the boss's family, has always felt that someone is spying on her. You're not the one spying on her, are you? ”

Everyone's eyes were fixed on Naqigu, but Naqigu was unexpectedly silent, with a cold face, as if in deep thought. With years of experience in psychological research, Ouyang Fan felt that there was something wrong with Naqigu. Could it be that Zheng Hua's murder case really has something to do with him?

After a long time, Na Qigu said with a stern face: "I know who did it!" ”

"Who?"

"Wang Dong!"

"Huh?" Several people were taken aback.

Ouyang Fan shook his head: "What nonsense are you talking about?" Wang Dong, isn't that your new girlfriend? ”

Na Qigu's expression was extremely serious: "Let me tell you, Wang Dong came to me to go undercover." ”

"What, undercover?" Ouyang Fan laughed.

Na Qigu was suddenly a little annoyed, his eyes looked ahead, and he actually scolded: "Damn! Want to go under the knife on me? ”

Seeing that his demeanor was very wrong, several people were surprised. Liu Lin hurriedly dragged Ouyang Fan. Ouyang Fan didn't dare to make a sound. Looking closely at Naqi Valley, it is indeed a bit crazy. Could it be that this person has gone mad?
