Because of Shihu's stop, Bao Zheng's expression was frightened: "What's wrong?"

Shihu blinked: "I don't know."

Bao Zheng's just gathered anger almost relaxed. Just when he wanted to teach Shihu a lesson, he found that he had already run to look at the altar.

Bao Zheng was left aside by him, and he was very embarrassed: "I said..."

A "bang!" interrupted his words.

"Who?!"

Both of them became nervous. Bao Zheng raised his knife and slowly approached the sound, bypassing the Guanyin statue. With a "gulp", a figure rolled out of the Guanyin statue.

Bao Zheng chopped down with his knife subconsciously, but because the blade reflected the moonlight, he could see the man's face clearly. He stopped in a hurry and shouted out his identity.

"Master Lu!"

Before he could figure out how Lu Zheng could appear in this place, a small cry of surprise came from Shihu behind him. He turned around quickly and found a black shadow crawling out of the ruins of the broken temple and running out quickly.

"Where are you running to!" Bao Zheng glared at him and chased after the black shadow.

Shihu looked at the semi-conscious Lu Zheng at a loss, but finally walked over and carefully helped him up. There was a cut on Lu Zheng's forehead, and blood flowed down his cheeks, with a few strands of black hair clinging to it.

Shihu examined him and took his pulse, confirming that he only had this one wound and was probably knocked unconscious by someone. He was relieved. He knew that this young master was of noble status and didn't want to cause trouble for Brother Bao because of him.

Bao Zheng lost him not long after he ran out of the ruined temple. He was worried about Shihu and Lu Zheng in the ruined temple, so he came back quickly.

Shihu was bandaging Lu Zheng. Because Bao Zheng was often injured, he carried gold sore medicine and bandages with him, which came in handy now.

"Is he okay?" Bao Zheng looked at Lu Zheng, whose face was pale, with concern.

Shihu whispered, "We should send him to see a doctor..."

"You're right." Bao Zheng frowned, "Wait, should we send him back to the Duke of Ying's Mansion..."

"Hmm..." Lu Zheng groaned and slowly opened his eyes.

Seeing him wake up, both of them breathed a sigh of relief.

"Master Lu, how are you?" Bao Zheng waved his hand in front of him.

Lu Zheng felt a splitting headache. His memory was still stuck on the time when he fell at the back door of the temple. He saw the murderer rushing towards him and threw the fire stick at him in a hurry. He was lucky because the fire stick that couldn't be blown to light actually ignited by itself. The murderer was shaken and took a step back. He wanted to take this opportunity to run away, but was hit on the forehead by something and fainted. When he woke up again, he saw Bao Zheng and Shihu.

"What happened..." Lu Zheng sat up slowly against Shihu, holding his forehead and said in pain.

Bao Zheng told him what happened and looked at Lu Zheng worriedly: "Master Lu, let's take you back first."

Lu Zheng touched the wound on his forehead. The previous fear seemed to fade away, and what remained was the excitement of trying and the gradually clear ideas.

"Wait a minute." Lu Zheng refused their help and stood up by himself with the help of a pillar. Then he looked at the back of the Guanyin statue in the moonlight. There was originally a piece of red cloth there, but as Lu Zheng rolled down, the red cloth was also pulled down, leaving only a big hole.

Lu Zheng reached in and touched it. As expected, compared with the dirty temple, the hole was very clean.

Bao Zheng was also stunned by the hole. When they checked the ruined temple before, they checked inside and outside, but they didn't expect that there was another world behind the Guanyin statue. The size of this hole can accommodate an adult man. Lu Zheng rolled out of the hole because he was not yet fully grown.

Lu Zheng said confidently: "The murderer is about 30 years old and has an ordinary face. He lost his mother when he was young, and his father beat and scolded him, which made him cowardly and cruel. When he grew up, he joined the army. He must have been injured on the battlefield, so he retired and returned home. After returning home, the matchmaker introduced him to a beautiful girl, but this girl was not decent. She was secretly in love with other men before getting married, and he didn't stop after being found out. "Lu Zheng said, seeing Bao Zheng and Shi Hu staring at him blankly, he felt a little embarrassed: "What? Did I say something wrong?"

"No... How did you guess it?" Bao Zheng stammered, "It

's as if... As if you know the murderer." Lu Zheng was speechless

for a moment. In this dynasty, there was probably no such term as psychological profiling. He really didn't know how to explain it to them.

Fortunately, Bao Zheng quickly changed the question: "Since the murderer has killed someone, why did he run back? Isn't he afraid of being caught?"

Before Lu Zheng could answer, he heard Shihu whispered beside him: "Self-abuse."

"What?!" Bao Zheng almost choked on his own saliva.

The three of them walked around the Guanyin statue, and Shihu pointed to the white stain on the legs of the altar.

Bao Zheng was speechless. Although Lu Zheng had already guessed it, he was still shocked by the murderer's heavy taste.

"That's it." Lu Zheng coughed, "The murderer originally regarded the Guanyin statue as his mother, which was a manifestation of his cowardice. But after he committed the crime and experienced that kind of pleasure, the cruel side began to prevail. He was obsessed with this feeling, so he committed crimes one after another. But all the cases after that did not bring him as much pleasure as the first one, which is why he came back to this dilapidated temple."

"This... this..." Bao Zheng struggled for words, and finally found that he still couldn't express his feelings in words.

"To kill innocent women for such a reason is no longer a human being." Shi Hu said suddenly, "If he was afraid the first time he killed someone, he was already intoxicated by it the next two times. He even retained the consciousness of those girls and let them watch their skins being peeled off."

Lu Zheng and Bao Zheng were both stunned.

"What did you say?!"

Shihu's voice was extremely cold: "In the first case, the bloodstains were almost nearby. The murderer must have skinned the victim some time after his death. As for the second and third cases, the scene was almost filled with blood. A dead person could not bleed so much. Although the victim in the third case seemed to be suffocated, he was not strangled to death, but died after all the blood had flowed out."

Both Lu Zheng and Bao Zheng felt a chill spreading from the soles of their feet to the top of their heads.

Shihu continued, "In addition, the murderer's arm should have been injured. When he wanted to strangle the first victim, his arm should have been cut by the victim's hairpin." As he spoke, he took out a copper hairpin wrapped in a handkerchief from his sleeve.

Bao Zheng couldn't help but shout, "Where did you find the hairpin?!"

Shihu's professional look was frightened by his voice and turned into a pitiful one. Not only was the copper hairpin stolen, but he also had to finish the rest of his words pitifully: "The wound should be very deep, and the victim's undershirt should have been used by him to wrap the wound."

Lu Zheng breathed a sigh of relief. Everything he said was based on speculation. Maybe the murderer could be found, but it was far from enough to convict him. Fortunately, Shihu found evidence.

"Put the hairpin away. It's a very important piece of evidence."

Bao Zheng responded absentmindedly, holding the hairpin high up. Shihu couldn't reach it and didn't dare to really snatch it, so he could only look at him with a frown in grievance.

Lu Zheng covered his forehead with his hands: "Stop making trouble, let's talk about business first."

"The murderer is a male, about 30 to 40 years old. He lost his mother at a young age and served in the army. He came to Yanjing in recent years and lives alone. His job allows him to go out during curfew. He is taciturn and cautious. He has a lower status among his colleagues and appears cowardly and dull." Lu Zheng listed the characteristics of the murderer one by one, "He was injured recently, and the wound is very deep, but with his personality he probably won't go to see a doctor. It is very likely that he applied the medicine himself, which means that he always has golden sore medicine at home..."

The shadow in the dark gradually took shape.

Bao Zheng thought: "It's the Patrol Camp!"

"What?"

"The murderer is from the Patrol Camp!" Bao Zheng walked around excitedly, "Why didn't I think of that... that's not an iron bell at all, it's the Patrol Camp's token!"

Lu Zheng was confused by him: "What are you talking about, how can the murderer be from the Patrol Camp?"

"We were all misled by what Zheng Dahe said!" Bao Zheng's eyes were shining, "He said that they heard bells on the night of the murder, so we all thought the murderer was a peddler or a Taoist priest. In fact, it was just the sound of the patrol camp's token hitting the scabbard."

Afraid that Lu Zheng and the others would not understand, Bao Zheng directly took out his own sword to demonstrate. He hung his Jingzhao Prefecture token on the side of the sword. As he walked, the token collided with the scabbard, and indeed made a crisp sound of metal. Even because of the change of his pace, the sound was sometimes loud and sometimes soft, which really fits the description of the night watchman Zheng Dahe.

"I have always felt that there was something fishy about that night watchman." Bao Zheng sneered, "He must have seen the murderer, or at least saw his back, and knew that the other party was from the patrol camp, but he was afraid of retaliation, so he dared not tell anyone, and even blamed everything on ghosts and gods. I must interrogate him severely when I get back and make him tell the truth."

"Then the murderer?" Lu Zheng hesitated.

Bao Zheng patted his chest and guaranteed: "Don't worry, you have explained it so clearly. If I still can't catch the murderer, I will not be a constable anymore."

"That's good." After getting the guarantee, Lu Zheng's anger was relieved, and he suddenly felt a splitting headache, and stars appeared in the sky before his eyes.

"Help..."

"What?"

"I feel like I'm going to faint."
