Mo Xiaoqing raised her hand and saw a blood spot. She took a magnifying glass and flashlight to take a closer look and saw a silver needle stuck in the back of the wooden chair.

She pulled it out with tweezers and observed it carefully, only to find that it was a thin tube like a needle.

Mo Xiaoqing shouted, "Dear colleagues, I found something very strange, come and have a look."

Liu Xiaobo rushed over as fast as he could, "Huh? Xiaoqing, where did you find this?"

He took the tweezers and examined it carefully, "It's very strange, this needle is very special, one end is hollow.

Why would there be such a special needle stuck in a wooden chair in the church?"

The criminal police all have a professional sense of smell. The assistant from the forensic department took out instruments to conduct on-site inspection and obtained a very surprising news:

human blood was detected in the special syringe. As for the specific report, they have to wait for relevant inspections after returning to confirm it accurately.

Upon hearing this, Liu Xiaobo made a bold guess: "Could this syringe be related to Wang Tao's death?"

Other police officers also agreed, "It is very likely. The church is a place for worship and prayer. Common sense says that there shouldn't be such a shaped needle."

Mo Xiaoqing quickly reported the news to Xu Yao, and the excited voice of Captain Xu was also heard, "Mo Xiaoqing, ask the Forensic Department to examine the needle as quickly as possible, and urge the Forensic Department to re-examine Wang Tao's body.

As long as the blood on the needle hole is confirmed to be Wang Tao's, then I am 90% sure that Wang Tao's cause of death was not strangled."

Mo Xiaoqing's face was full of doubts, "Then how did Wang Tao die?"

Xu Yao actually kept the secret at the critical moment and just asked Mo Xiaoqing to stare at the Forensic Department.

The police officers returned to the criminal police team in a hurry. Liu Xiaobo and Mo Xiaoqing were in the same car.

Liu Xiaobo sat in the driver's seat and always observed Mo Xiaoqing through the rearview mirror. When he looked at her for the fifth time, Mo Xiaoqing could no longer bear it.

"Xiaobo, when did you become a woman? Just say what you want to say!"

"Well...well, I heard recently that you were taking care of the injured Captain Xu Yao..." Liu Xiaobo stammered.

"Yeah, what's wrong?"

"You are still sleeping in the same room?" Liu Xiaobo's voice rose a few decibels, and when he found that the nearby police turned their heads to look over here, he lowered his voice again.

Mo Xiaoqing got angry, "Xiaobo, just say what you want to say."

Liu Xiaobo was shocked and said, "Wow, Captain Xu's girlfriend and Professor Li are so generous."

Mo Xiaoqing finally understood that Xu Yao had a girlfriend, and Li Tianfeng was openly pursuing her. Now it was very unreasonable for her to take care of Xu Yao. Only then did she realize the eyes of others. It

was indeed inappropriate, but Mo Xiaoqing didn't want to explain, "I didn't agree to Li Tianfeng's pursuit, and I just took care of him as an assistant to Captain Xu. The hospital has surveillance, you can check it."

Liu Xiaobo saw that Mo Xiaoqing's face was flushed, and hurriedly explained: "Xiaoqing, don't be angry, I just heard my colleagues discussing this matter and felt strange, so I asked by the way."

"What did my colleagues talk about me?" Mo Xiaoqing was in a bad mood.

"Xiaoqing, don't take it personally..."

"Speak!" Mo Xiaoqing almost yelled, shocking Liu Xiaobo, and told him the truth:

"It's just... they said you took the initiative to ask for permission to look after the boss, and the criminal police team also required the newly transferred female police officers to create conditions to be alone with Captain Xu. They said you... they said you..."

"What did they say about me?" Mo Xiaoqing forced herself to stay calm, but her voice trembled unconsciously.

"It's just that you took the opportunity to get promoted, saying that although Captain Xu had a girlfriend, he was not married, and you did have a chance to take advantage of the situation..."

These words were like poisonous thorns piercing Mo Xiaoqing's blood, and her whole body suddenly became numb and stiff.

As the saying goes, people's words can be scary, she finally realized it, but what did she say?

She said that she had never thought about Captain Xu, but the fact was that she had always been secretly in love with Xu Yao.

The only thing she could do was to shut up and try to stay away from the Xu team.

After returning to the police force, Mo Xiaoqing didn't think about anything else, just waiting for the report on the syringe, which was probably about 3 pm.

Mo Xiaoqing rushed to the forensic department to get the report, and as soon as she knocked on the door and entered, she asked,

"Excuse me, can I get the report?"

Lin Yalin looked at the reckless Mo Xiaoqing, and couldn't help but frowned, and handed the report over unhappily.

"You are so lucky. You found this special syringe and it is indeed related to Wang Tao's case. After testing by our department, the blood left on the syringe came from Wang Tao."

Mo Xiaoqing happily took the report and couldn't help but sigh, "Captain Xu is really amazing. He said that as long as the blood in the syringe came from Wang Tao, he can probably guess the cause of Wang Tao's death."

As soon as these words came out, Lin Yalin nodded in approval, "Of course, he has rich experience in the police force. Doesn't everyone call him a hard-core detective!"

Lin Yalin handed another report to Mo Xiaoqing, "This time our department took the initiative to admit the mistake. It was indeed our department's negligence that led to the wrong judgment of the cause of death."

As she spoke, she turned on the video, and Xu Yao's face appeared on the other end of the phone.

"Your captain has called me to re-examine the body. He suspects that Wang Tao was not strangled to death, but was poisoned.

His inference is indeed correct. I re-scanned the body in all directions this morning and found a pinhole behind Wang Tao's neck.

Because the pinhole is very small and is covered by the strangulation marks above, our assistant was negligent when scanning the body. In addition, there are my subjective mistakes. My work status has not been good recently."

Lin Yalin said to "Xu Yao, the report is out. As you guessed, the syringe is filled with biological toxins, but we haven't found out what type of poison it is. A needle hole was found on the back of Wang Tao's neck, which is the same size as the needle."

Xu Yao's voice came from the other end of the phone, "The syringe should have been ejected from a special device, and this toxin can quickly kill people. After the murderer ejected the poison needle, he immediately took out a rope and strangled Wang Tao's neck, creating the illusion of strangulation."

"I apologize for misleading your investigation. I will submit a report to the higher authorities and admit my mistake."

Mo Xiaoqing was a little flustered when she heard Lin Yalin apologize to her. She shook her hands quickly, "Sister Lin, please don't say that. It's impossible for everyone to be perfect.

What's more, the murderers we face are of all kinds. The criminal methods they use are all kinds of strange. No one can judge 100% accurately. Otherwise, there will be no unsolved cases in this world."

Xu Yao also said, "Mo Xiaoqing is right. Lao Lin, you are already great!"

"Don't call me Lao Lin!"
