Suddenly, Yue Yang's phone rang, and he hurriedly answered it when he saw that it was Han Li calling.

"Hey, Sister Corpse, what did you find?" Yue Yang asked.

"I re-conducted the autopsy, and this time I detected a slight tetrodotoxin in Kim Jong-ryong's stomach."

Tetrodotoxin is arguably nature's most potent toxin, and people with severe poisoning can die within minutes.

"What does it mean to be slight? What was the murderer's purpose in doing this? Yue Yang hurriedly asked.

"Tetrodotoxin is highly toxic, a slight overdose can cause death, but if it is properly controlled, then the victim will be paralyzed all over the body, and what is even more terrifying is that he still maintains a clear mind at this time, simply put, the brain is sober and the body cannot move, the deceased drank beer before death, and ate edamame and peanuts."

The secret of Kim Jong Long's slaughter was cracked, it turned out that he was poisoned, after the poisoning, he couldn't move at all, and completely became a lamb to be slaughtered, he watched his fingers chopped off one by one in a state of complete clarity, the pain was unimaginable, the location of the No. 27 rental house was remote, even if he called the heavens, no one could hear it.

The brothers who went out to search not long after also came with good news, they found a plastic bag in the creek behind, which contained a pair of white gloves, two bottles of mineral water, two cans of beer, and a deck of playing cards, and a large number of edamame pods.

After laboratory testing, the mineral water bottles were adulterated with potassium cyanide, and the strange difference in potassium cyanide concentration between the two bottles of water was very large. One of the two cans of beer was found to contain tetrodotoxin.

Several people returned to the scene of the crime again, and this time Han Li also followed.

Now they only need to restore the scene to speculate the entire process of the crime, in order to avoid destroying the evidence, Guo Shulin deliberately sold another copy according to the contents of the bag.

Guo Shulin stood outside the door with something as Yue Yang asked, while the others stood inside the house.

Yue Yang stood at the door to explain to everyone.

"On the night of the crime, the murderer knocked on Kim Jong-ryong's door with beer and edamame, and he and Kim Jong-ryong knew each other, but the two did not have a deep relationship, they had no contact, and they rarely contacted each other."

Guo Shulin, who was outside the door, hurriedly knocked on the door.

Yue Yang opened the door and continued: "Jin Zhenglong was a little surprised, but when he learned that the murderer was coming to him for a drink, he still welcomed the murderer into the house, took the door with him, and after sitting down, the murderer handed the beer that had been prepared long ago to Jin Zhenglong, and the two of them played cards while drinking......"

"Wait, that's not right here." Han Li stopped Yue Yang and said, "I have checked that only one of the two cans has Jin Zhenglong's fingerprints on it, and there are no two bottles of water, playing cards and bags, if you can't figure this out, your deduction will be considered a failure, and this needs a reasonable explanation." ”

"Don't play with poker? Why? There are no fingerprints on the mineral water, how does he drink the water? Wearing gloves? Guo Shulin asked.

Han Li once again denied Guo Shulin's opinion, "Not necessarily, the murderer can feed him water." ”

Yue Yang looked at the playing cards and pondered for a while, and understood the reason.

"I understand, at first the murderer did not take out the playing cards, because he wanted to play a big one, Kim Jong Long thought he came to find a drinker, in fact, he came to ask for his life, when Kim Jong Long felt that something was wrong, it was too late, he was hit with tetrodotoxin and couldn't move at all, at this time the murderer finally showed his true colors, he took out the playing cards and Kim Jong Long played the game, the stakes of the game are also very simple, that is, lose once chop a finger, at this moment Kim Jong Long can only be manipulated, Watching his fingers being chopped off again and again, chopped off his fingers and chopped off his hands, Kim Jong-ryong begged for mercy again and again but to no avail, when he chopped off his hands, the murderer played a choice game with him, the murderer took out two bottles of water for Kim Jong-long to choose, maybe he told Kim Jong-long as he chose the right one, this is a cat playing with a mouse, the cat will take the initiative to let the mouse run and then catch it back, and the cycle repeats, until the mouse can't run and then eats it, No matter what bottle of water Kim Jong-ryong chooses, it is a death, because the murderer did not intend to let him go at all, so Kim Jong-ryong was played to death, and then the murderer cleaned up the scene, took everything he brought, and then left the rental house with a severed finger after leaving the number. ”

Lose a handful and chop a finger, everyone didn't expect the scene in the movie to really happen, sure enough, art comes from life, you can imagine how desperate Kim Jong-ryong was before he died, the whole process was very cruel, his mind and body suffered great damage, the murderer and he may play a simple guess game, two playing cards to guess who is big and who is small, win and continue to play, lose and chop his fingers, he watched his fingers being chopped off but couldn't move, the whole process must have lasted a long time, Kim Jong-ryong was played to death in despair.

The truth surfaced, and the murderer's brutality was so brutal that even Luo Yuan couldn't help but gasp, and when he thought that he might be a serial murderer, he couldn't help but feel a chill down his spine.

"How big is the hatred to be so vicious? The hatred of taking his wife, the hatred of killing his father? Han Li couldn't help but sigh.

"Not necessarily, there is an unwritten rule in the casino, that is, to chop a thousand hands." A similar scene has been seen by Yue Yang.

Which one of the people who dare to open a casino is not a ruthless master, usury can still play side balls, and opening a casino is purely illegal, and the casino may incur death if it pays out thousands of dollars or does not pay back the money owed to the casino.

Jin Zhenglong happens to be an indiscriminate gambler, and Yue Yang can't even go to Nancheng to find the fourth child.

After a busy day, there was still no clue, and everyone returned to the public security bureau again, and everyone had an argument over the characterization of the suspect.

Yue Yang believes that the suspect is definitely not a migrant worker at the bottom of the society, potassium cyanide may still be available, so tetrodotoxin is not so easy to get, from the murderer's control of the amount of toxins, it can be seen that he knows toxins very well, should be a person who has been in contact with these toxins for a long time, how can such a person be a migrant worker.

And the murderer's anti-reconnaissance ability is not like that of a migrant worker.

The murderer cleaned up the footprints in the house, but only left the footprints at the door, which was too strange, and it felt like it was deliberate, in order to confuse the public.

Does wearing protective shoes mean that you have a humble status?

No, this is a delusion, Yue Yang thinks that the murderer is acting in the old suspicion array.

In Yue Yang's opinion, this person is not only not a farmer, but also not an ordinary person, this person has been studying toxins for a long time, and knows the toxic dosage of toxins well, so he should be an expert or a scientific researcher engaged in this field.

Guo Shulin did not agree with Yueyang's statement, Jin Zhenglong does not have such tall relatives and friends at all, potassium cyanide and tetrodotoxin can be bought online, and wearing labor protection shoes does not mean that his education is low, and migrant workers also have people who are proficient in chemistry.

For this reason, Luo Yuan divided the work between the two, Yue Yang still went to investigate the fourth child in Nancheng, and Guo Shulin went to find out the social relationship of Jin Zhenglong.
