Early the next morning, Wen Qiao took out a comprehensive autopsy report.

Chen Yuliang did die of anaphylactic shock, and five or six red spots suspected of insect bites were found on his neck and arms.

"Some amines, peptides and polymer proteins were extracted from his wounds, including neurotoxic protein, phospholipase A, hyaluronidase, etc., which are the main components of wasp toxin."

"After Hu Feng stung a person, the venom in the poison sac enters the human bloodstream, and the antigenic component Antigen5 in it will quickly induce IgE-mediated immediate allergic reactions in the body. Substances such as histamine and kinin in the venom will promote the occurrence of local inflammatory reactions, and local wounds will appear painful, red, swollen, papules and erythema, or necrotizing lesions, and in severe cases, it can cause systemic inflammatory response syndrome, accompanied by systemic multi-system damage such as circulatory system, nervous system, and urinary system. Melittin has strong cytotoxic side effects, which can directly lead to acute tubular necrosis, interstitial nephritis, renal cortical necrosis, and in severe cases, it can cause acute renal failure, liver injury, myocardial injury, respiratory failure and nervous system damage. Phospholipase A2 will work synergistically with melitin to cause acute hemolytic reactions and allergic reactions. ”

Wen Qiao finished the long list of professional terms above with an expressionless face, and although the policemen below couldn't remember what peptides and enzymes for a while, they still understood that this wasp toxin was not a joke.

Ling Ling said with palpitations: "It's so terrifying! I've been stung by bees before, so I'm not going to die! ”

"Poisoning reactions caused by bee venom are not as fatal, and the real danger is allergic reactions." Wen Qiao added: "We tested Chen Yuliang for allergens and confirmed that he was severely allergic to Antigen5, the antigen component in bee venom, and that acute respiratory failure caused by allergies is very dangerous and can cause death within minutes if not treated in time." ”

Ling Ling listened to his words and was even more afraid: "We can't hide a hornet's nest in any corner here, right?" Shouldn't it be thoroughly inspected and found out and eliminated? ”

"yes, I don't dare to stay here anymore." Zhou Zhen echoed.

"That's the most interesting part of this case." At this time, Wen Qiao interrupted their discussion.

"I've looked around, and there's no wasp nesting here." Wen Qiao gave them a reassuring pill first.

"Those wasps are running for Chen Yuliang alone."

When the people heard this, they were even more astonished.

What does that mean? Could it be that they know each other? Zhou Zhen made a joke that was not very funny.

"All animals are attracted to food, sharks are attracted to blood, and bees are attracted to nectar. And Chen Yuliang is their food in the eyes of these wasps. ”

"There is a traditional medicinal plant in Southeast Asia called Dabaibu. When its seeds ripen, the oily bodies on them emit a scent that disguises itself as prey for wasps, with the help of insects to spread their seeds. Once the smell of the oleoplasm is caught by the wasps, they will pounce on the propagators like a hunt, frantically attacking and biting the seeds that enclose the oleoplasms. ”

"After 'killing' the seeds, they will try to break them down and carry them back to the nest, but most of them will be discarded halfway through, which completes the planting of most of the seeds."

"Vesps are ferocious by nature, they are inherently aggressive, and because of their special stinger structure, they can easily pull out the toxin released by their prey to carry out multiple attacks. Therefore, if they are unfortunate enough to be identified as prey or enemies by wasps, they will not give up easily. ”

Everyone was dumbfounded when they heard it, and they all vaguely guessed the meaning of what Wen Qiao said just now.

"An oleosome was extracted around Chen Yuliang's wound. It's just that there are no comparative experiments on Dabaibu seeds now, so it is not completely certain that the substance found on Chen Yuliang is the oleosomes on Dabaibu seeds. ”

"I knew it couldn't be a coincidence!" Ling Feng took the case and said angrily: "Everything was planned by Huang Yang, and he revealed his identity in order to lure out this policeman who supervised Jasmine's case back then, so that he could design to kill him!" ”

At this time, Zhou Zhen suddenly raised his hand weakly and asked, "But...... Why does Huang Yang have to lure people into our bureau before doing it? His method can kill people at any time and anywhere, unknowingly? Just like the few people he has killed in the last dozen years. ”

"Of course it's because of hatred! He wants to take revenge on him and humiliate him! Ling Feng said hatefully, "What could be more humiliating than killing a policeman in a police station!" ”

"Maybe you're thinking too much." Wen Qiao suddenly spoke calmly: "He has no interest in anyone who has nothing to do with that old case, so don't think too much about yourself." ”

"What do you mean by that?" Ling Feng was already haunted by what happened yesterday, but now that he was put on the table by Wen Qiao, the fire in his heart was about to burst out.

But Wen Qiao just glanced at him lightly: "It means that Huang Yang killed Chen Yuliang just to let him die, and there is no humiliating drama that you make up in your brain, so you don't need to think so much about making yourself unhappy." ”

"Why do you say that?" Ling Ling knew what his brother was thinking, so he hurriedly answered and asked.

"His modus operandi in the past, burning charcoal, poisoning, drowning, and electrocution, since they are to be faked as accidents, they must be clean and leave no traces. Chen Yuliang's crimes in the Jasmine case were no less or heavier than others, and there was no need for him to take special care of him. ”

"Then why does he have to do it with us?" Ling Ling then asked.

"I think there are two reasons. First, because Chen Yuliang and Qin Nanzhu are the last two people who need to atone for his daughter's sins, he is willing to make a desperate bet, even at the cost of being completely exposed. Second...... I heard that Huang Yang asked Chen Yuliang a question yesterday. ”

Huang Yang asked him if he had received money from the Li family, and whether the money he collected was enough for the value of three catties of gold, but Chen Yuliang denied it.

"Yes, he did." Ling Ling said, "Can ...... What does it matter? ”

"Yesterday's face-to-face questioning was indeed specially arranged by Huang Yang, you think the police are interrogating him, but in fact he is interrogating the police. He relaid this old case in front of Chen Yuliang to let him make a choice. ”

"If conscience can be bought and sold, and the Li family's bid can make Chen Yuliang discard his conscience, then, if his bid is higher than that of the Li family, can he buy back Chen Yuliang's conscience?"

"If Chen Yuliang told him the truth about the original price, maybe he would not have died, and if the original price was less than three catties of gold, it means that boxwood once had a glimmer of hope to save Jasmine, but he gave up ignorantly."

It's a pity that Chen Yuliang didn't answer his question, but directly denied the existence of this matter. Although he said that it was a pity, Wen Qiao's face did not show the slightest regret.

"This is the multiple-choice question of Gu Won Bird, if you answer incorrectly, you will accept the punishment of death."
