Recalling the past, when Zhao Yu was investigating the Beichuan Demon Case, he entered the western Sichuan Province, but he had never been to Andu.

An is the capital of western Sichuan Province and is the leading city in the southwest my country.

When Zhao Yu arrived by the high-speed rail, it was already ten days late.

The climate in Andu is slightly hotter than Yaoming, and it has already entered the rhythm of summer.

Because he said hello in advance, Zhao Yu didn't like to mobilize all the troops, so the only one who came to greet Zhao Yu and others was Zhang Ling, the criminal police captain in charge of the Ghost King case of Andu Police Station.

When Zhao Yu heard this name before, he thought he was another female criminal police captain, but after meeting him, he found that Zhang Ling was not only a perfect male captain, but also a middle-aged greasy uncle with no hair on his head.

Nowadays, Zhao Yu has long been famous and resounded throughout the criminal investigation community, so when the two sides were interviewing and introducing, Captain Zhang Ling was obviously a little nervous and restrained, and even a little bit of fear.

It is estimated that he had already heard of Zhao Yu's unique detective ideas and his domineering temper. Therefore, during the conversation, Zhang Ling always maintained a cautious state, afraid that he would offend this detective if he said something wrong.

However, Zhang Ling is also a smart person. He should have done his homework in advance and understood that Zhao Yu did not like too much social engagements and courtesy. So, when Zhao Yu got on the bus, he immediately started reporting to Zhao Yu.

"The deceased is named Niu Jinkui, a teacher at Tongle Art School, specializing in teaching guqin," Zhang Ling's voice was loud and his words were straight and his voice seemed to have learned broadcasting and hosting. "He is 62 years old this year, and he was an actor from the Sichuan Opera Troupe in the past, proficient in various musical instruments..."

"Oh?" Zhao Yu was slightly stunned, "Is he another opera singer?"

"Sichuan Opera?" Cui Lizhu interrupted and asked, "Is there any change in her face?"

"Well...yes, face change is just one of them..." Zhang Ling looked at Cui Lizhu and did not dare to stay on this little beauty with a baby face, so he continued to introduce, "Niu Jinkui did perform on the stage, but most of them were little tricks. His main job was still a musician!

"However, as a musician, I used to be a well-known figure in our local area. I once appeared on CCTV programs! However, this person has a bad character. He has a criminal record of being a prostitute 10 years ago.

"Later, he had a crush on a married woman and was caught on the spot. Since then, his reputation has plummeted. Not only did he divorce, he was also fired by the troupe and had to go to school to teach the guqin..."

"Oh..." Ran Tao nodded and said, "It seems that this person is not a fuel-efficient lamp!"

"He lives alone now," Zhang Ling said, "so he has not reported the case for so many days. On the school side, he just saw that he had not been at work and called him, but the phone was turned off and he did not go into it in depth...

"Also, the guqin at the crime scene is also Niu Jinkui's own!

"It is said that the guqin is very valuable, it is a handmade guqin..."

"Oh...so...has the victim's home searched? Have you found it?" Zhao Yu asked a professional question directly.

"Searched," Zhang Ling hurriedly replied, "No suspicious traces were found in the deceased's home, and his mobile phone, wallet and other valuables were not present, which means that the deceased's home was not the first scene. He should have been kidnapped by the murderer outside!"

"Oh..." Zhao Yu pondered for a moment and asked again, "So, what kind of temple is the first scene of the crime?"

"Yes!" Zhang Ling nodded and said, "It's Guandi Temple. According to forensic identification, it should be the first crime scene. The deceased was taken there by the murderer three days ago and then killed!

"According to the autopsy report, the deceased died of tets poisoning, which is what we often call poisonous rats strong. I believe..." Zhang Ling signaled his cell phone, "You have seen this report, right?"

"Yeah..." Zhao Yu nodded.

"The murderer has definitely made sufficient preparations in advance," said Zhang Ling. "The solubility of poisonous rats in water is very low. However, he used a chemical reagent containing acetone to dissolve the poisonous rats, and then injected it into the digestive tract and respiratory tract of the deceased by injection, which accelerated the opponent's poisoning speed!

"According to the forensic estimates, the deceased should be killed in less than 15 minutes after being poisoned!

"If we consider Niu Jinkui's age and physical condition, perhaps the entire death process will take less than 5 minutes!"

As soon as this said, Zhao Yu immediately fell into deep thought.

Zhang Ling waited for a while and saw that Zhao Yu was almost thinking, so he continued to say: "The poisonous rat is a strong poison. Once it is used, accidents occur frequently, so in 1991, it was completely banned from production and sales!

"After taking the poison, the symptoms are very serious, which can affect multiple systems of the human body, such as convulsions and vomiting, until consciousness is lost and the body is stiff!

"The forensic doctor said," Zhang Ling said, "the victims had obvious signs of binding. They suspected that the deceased was tied to the seat by the murderer when they were poisoned.

"After someone dies, their body will immediately become stiff and pressed against the seat, so after someone dies, the murderer untied the rope..."

"Wow..." Hearing this, Choi Lizhu couldn't help but say, "The murderer is evil enough. I feel that his brain must be sick!"

"Captain Zhang," Zeng Ke asked Zhang Ling at this time, "Have you found the file information of Tao Yulan's case? Was the poison used by Tao Yulan also powerful? "

"Well...this..." Zhang Ling looked at Zhao Yu uneasyly, and then said, "The case of Tao Yulan happened in the early days of liberation. At that time, Andu was not the capital of western Sichuan Province, so the relevant files had to be found in Chongyang City!

"Well, my colleagues over there are already looking for..."

After saying that, Zhang Ling looked at Zhao Yu again. After finding that Zhao Yu was not angry, he continued with relief: "It is definitely impossible for the poisonous rat to be strong.

"We have checked the information. The poisonous rat is invented by German scientists in 1949. By 1953, it was not popular in our country, so... the poison used by Tao Yulan should be something else!"

"After all, the two cases are separated by 66 years..." Wu Xiumin said to Zhao Yu, "Team leader, I think we should focus on this case first!"

"Well..." Zhao Yu nodded and asked Zhang Ling again, "What's going on in the crime scene? Have you found witnesses or surveillance videos?"

"This...well..." Zhang Ling stammered for a moment and said helplessly, "No witnesses have been found yet. The area around the crime scene is a demolition area, and the surveillance equipment there has been damaged long ago!"

"Where is the driving recorder?" Ran Tao interrupted and asked.

"The demolition area is full of alleys, and cars cannot enter at all, so the driving recorder cannot work... We can only investigate through surveillance on the outer roads and some shops' surveillance, but no clues have been obtained yet..."

"Hu..." Zhao Yu breathed out and said, "By using the syringe alone, it means that the murderer was prepared for a long time and must have surveyed the terrain!
