When it was dawn, Zuo Chong quickly walked into the yard where Yuan Chuyu's body was found. As soon as he looked up, he saw Ling Sanping sitting next to the body, gracefully tasting a cup of coffee.

Zuo Chong saw a lot of dead people, but he still couldn't do this by the other party. He frowned imperceptibly: "Doctor Ling, what is the result of the autopsy?"

Ling Sanping wiped his mouth with a handkerchief, handed Zuo Chong an autopsy record, and then came to the corpse to lift the white cloth to start reporting.

"The deceased, male, had no obvious trauma on the surface, his skin was light gray, his face was slightly blue and purple, and his nail bed was purple and blue.

Anatomy shows that there are a small amount of foamy secretions in the trachea, the lung tissue is darker and there is edema.

The heart has normal appearance, no obvious lesions, and the blood color is also dark red, which is a sign of poor coagulation.

His digestive system, especially the stomach mucosa, is highly congested and has significant edema, and is mildly inflamed in the small and large intestines.

At the same time, the brain tissue of the deceased was partially edema, liver enlarged, and tubular epithelial cells were necrotic."

Zuo Chong did not understand medicine, but there were so many abnormalities in the digestive system, nervous system and internal organs of the deceased, and it was obvious that he was poisoned, so he quickly asked: "What do you mean is the deceased died of poisoning?"

"good."

Ling Sanping picked up a tray, which was filled with green liquid. He looked at Zuo Chong: "We detected high concentrations of arsenate in the stomach of the deceased. This is a new poison. It is the first time I have seen it outside the laboratory."

“Arsenate?”

Zuo Chong recited it several times. Whether it was his previous life or this era, he had never heard of this substance, so he asked what the lethal amount of arsenate in Lingsanping was.

"The lethal dose of arsenate depends on a variety of factors, including the individual's weight, health status and intake method, but usually 200 mg of arsenate can cause death."

Ling Sanping paused after answering and gave a professional inference: "The murderer may not have used such a large dose, and the deceased's hands and feet were seriously distorted, which proves that his death process was very painful and the time was long."

"The murderer is forcing confession!"

Zuo Chong immediately replied, "If it is just for silence, the murderer has many ways to kill Yuan Chuyu. There is no need to use poison, and there is no need to use 200 mg of poison to kill him."

For example, ricin and cyanide can only be killed by a small dose. The murderer is so professional that it is impossible not to know.

Ling Sanping nodded: "Yes, the murderer watched the deceased die. Those who were poisoned by arsenate will feel a strong burning sensation and needle sensation, which is the most appropriate way to quickly force a confession."

Zuo Chong guessed that Yuan Chuyu told the murderer the bank certificate of deposit and the letter at this time, and the murderer had no intention of letting the other party go from beginning to end.

He thought in his mind and said, "You should take the body back to Renxin Hospital first, and I will let the parents of the deceased recognize the body."

Ling Sanping took off his gloves and shrugged: "No problem. After the case is over, I will hand over the murderer┴ to me. I want to study the toxicological effects of arsenate. OK, then I will go back first."

Looking at Ling Sanping who was leaving Shi Shiran, Zuo Chong's face turned dark. Before the person was caught, the guy had the idea of ​​captives. He was becoming more and more like a Frankenstein.

"Sub-stand, the indoor survey has been found."

Wu Jingzhong suddenly appeared beside Zuo Chong, and he was not convinced by his ability to take advantage of the situation.

"Go, say as you walk."

Zuo Chong and Wu Jingzhong walked towards the bungalow one after another, and then Wu Jingzhong's unslow voice rang in Zuo Chong's ear.

"The technicians found three blood stains and a rope in the basement, and the other party should have interrogated Yuan Chuyu there."

"Have the neighbors heard anything?"

"No, the basement is very deep, and there are bluestone slabs around the walls, which have a good sound insulation effect."

“Have you found any other places indoors?”

"The scene is very clean, the murderer has cleaned it up, and the technique is quite professional."

While they were talking, they walked into the room on the right. Wu Jingzhong pointed to a cabinet that was moved away in the corner: "Look, that is the entrance to the basement, with a mechanism inside. After entering, the cabinet above can be automatically reset, which is very hidden."

Zuo Chong turned around the wardrobe and found that the entrance was behind the wardrobe, with a diameter of about one meter, and went up and down through a steel ladder.

Following the ladder, he went down to the basement and roughly estimated the depth of the passage, which was nearly 5 meters. This is not a small project.

Not to mention the underground space, four square meters of soil are required to be excavated in this passage alone. Moreover, this is a secret project, and the excavated soil needs to be taken out a little bit. The enemy has spent a lot of effort on it.

Stepping on the bluestone floor, Zuo Chong saw Guqi and Gui Youguang standing there muttering something, and asked curiously.

"What have you discovered?"

"Sub-secretary, you are here."

Guqi turned around and said hello, and replied with a smile: "Youguang said that the murderer did not put the body in the basement, which means that the other party was just leaving for the time being and may come back in the future. We are discussing whether to ambush."

Zuo Chong looked at the big bald head in surprise. Is this the foolish man sure he will get one thing? The murderer tried hard to get the body to the ground and dug a deep pit of half a meter. There were indeed signs of opening this place again, but it was forgot to be ambushed, the other party was not that stupid.

He looked down at the brown blood on the ground and quickly looked away. These were all invalid clues. The reality is not a film and television drama. It is difficult for the victim to have the chance to leave the murderer's name. The key to solving the case is still the person.

"Old Wu, let me talk about Zhao Dayang's situation. Have the neighbors around you ever seen Yuan Chuyu?" Zuo Chong asked something.

"Okay, deputy post."

Wu Jingzhong reported Zhao Dayang's file, and the content came from the police station registration information. Of course, such as name, hometown, and social relations, all of which are fabricated. Only height, weight, and fingerprint are of some value, especially fingerprints.

After comparison by technicians, the fingerprints retained on Zhao Dayang's archives are consistent with those extracted by the Military Control Commission on the tea bowls of the teahouse.

This chapter is not finished yet, please click on the next page to continue reading the exciting content later! Although everyone knows that the suspect No. 3 is Zhao Dayang, and this matter has been confirmed by witnesses, knowing and identifying is the same thing, and whether there is evidence is another thing.

Intelligence work should not be careless. Once you develop the bad habit of fooling things, you will have to make up for it with your life and blood one day.

After talking about the current discovery, Wu Jingzhong began to report the results of the inquiry against his neighbors. According to the confessions of these people, they had never seen Yuan Chuyu or others looking for Zhao Dayang.

The reason is very simple. Most of the residents in this residential area are outsiders who moved west with the government. They are not familiar with each other and rarely deal with each other. In addition, the house is a single family, so no one will deliberately observe who the neighbors meet.

I'm afraid this is also the reason why Zhao Dayang sets his site here. If it is a local area with a large number of local people, not to mention a stranger, even if there is an extra dog, it will not be hidden from the neighbor's eyes.

Wu Jingzhong's report was over. Zuo Chong was a little uncomfortable with the turbid air in the basement, so he asked a few people to return to the ground, found a chair in the living room and sat down to continue discussing the next step of the work.

"Old Wu, you will follow up on Zhao Dayang's whereabouts next. Fake identity is also useful. I don't believe that the other party only rented a house with this document."

Zuo Chong first pointed out Wu Jingzhong's general. Everyone nodded silently about his words. It was expensive to make a perfect fake identity, and it was too luxurious to just rent a house. "Zhao Dayang" may have other traces in the mountain city.

The blessing of Japanese espionage and underground party is rampant. Today, the mountain city needs to register for everything, rent a house, accommodation, work, boats, and buses, all you need to provide documents. Regardless of whether this matter is strictly implemented or not, it is always a breakthrough.

Then, Zuo Chong smiled and turned to Guqi: "Lao Gu, do you still remember what we said before? Whether the case can be solved may be on here."

Gu Qi's mind was very fast and immediately understood the meaning of the conversation: "Do you want to mobilize the eyeliner around Yuan Chuyu, such as the student named Fang Quan?"

Zuo Chong did not affirm or deny it, and asked further: "You said, will that spy have been here too? If he knew that the place was investigated and we had clues about Zhao Dayang's involvement in spies, what would he do?"

"See a way to contact Zhao Dayang!" The three of them spoke in unison.

"Yes, he will contact Zhao Dayang, maybe..."

Zuo Chong said only half of his words, then stood up and ordered: "Let the news be released immediately at Central University. I want to let all the students know that Yuan Chuyu's body was found, and they also want to let them know Zhao Dayang's name."

Gu Qi and Wu Jingzhong, Gui Youguang's face was solemn, and he had no turning back when he opened the bow. It means that the enemy would know that he had been exposed.

But the three of them did not object. The worst result was that the enemy fled, and an exposed spy ran away.

This is indeed unfair to Yuan’s father and mother, but there are not so many fairness in the world. It is worth a gamble for the case.

Besides, the remaining enemies may have unexpected surprises. You should know that the 20,000 US dollars is still in the account, and the other party is so poor that he will take the risk of withdrawing money before escaping?

I don’t know how many heroes and heroes fell on the saying “Stop after doing this”. Zuo Chong felt that Zhao Dayang and his accomplices would not be able to help themselves in the face of such a large amount of money!

……………………

In a private house in the suburbs of Shancheng.

Zuo Chong racked his brains to find Zhao Dayang and a man with bandages in his arms sat at the table. The two of them looked at the stack of French coins on the table, their eyes slightly dull.

"Is this the only funding left?" Zhao Dayang was a little disbelief. Why did the funds for an intelligence team disappear in the blink of an eye?

The man looked angry and his fist slammed into the table: "Will I deceive you? The headquarters gave us the fiat currency from the Republic of China, but the fiat currency is depreciating every day. If this continues, we need to sell blood to carry out the mission!"

Zhao Dayang still didn't believe it and said tentatively: "We performed the last mission very well. Where is the bounty agreed by the headquarters?"

It would be fine if you didn't say this, but the man laughed angrily: "What kind of bounty is the order that it is not easy to make us sympathize with the country, and our parents will be proud of us."

"Not?"

"It's gone."

The conversation between Zhao Dayang and the man came to an abrupt end. The two looked at each other and fell silent, and then said two words almost at the same time.

"Dollar?"

After a few seconds, the man shook his head: "The enemy I encountered by the river is probably the Military Control Commission. The letters sent by Yuan Chuyu were not found, so it is not convenient for you and me to move for the time being."
