"A few days ago, Hua Yichang and Liu Deshan fled Nanjing on the Jianglong, and Section Chief Nakano and Lieutenant Colonel Shi Gong planned to arrest them.
After being arrested, the two men quickly surrendered and confessed their meeting place, person and password in Nanjing. Section Chief Nakano got the information and decided to kill two birds with one stone, intending to destroy the Nanjing Military Command Station and identify the thief."
Having said this, Lin Chuang looked at Nakano Yunzi. Nakano Yunzi was embarrassed and did not dare to look at him. He coughed lightly and lowered his head to drink tea.
"Because the matter is so important, I had the honor to go to Nanjing with Section Chief Nakano, and we took the Eryu. Please see, Section Chief Nakano and I lived in cabin No. 2 on the third floor, cabin No. 1 was Kameda, and Cabin No. 3 is Liu Deshan."
Two people living in the same room? Lin Ming said it without avoiding suspicion. What did he mean?
Everyone looked at Yunzi Nakano.
Nakano Yunzi raised his head and said: "Director Lin and I pretended to be husband and wife, so naturally we lived in the same cabin."
Lin Chuang smiled and said, "I'm just pretending. I haven't done anything. Don't think too much."
Everyone nodded solemnly, expressing their belief in this statement.
At the same time, my heart was full of disdain: "What about coaxing ghosts? Are you trying to hide it? A man and a woman live together in the same room. One takes it as a normal thing and the other doesn't care. It would be strange if he doesn't do something else."
Lin Chuang ignored everyone's dirty thoughts and continued: "The trip to Nanjing did not go smoothly. Because of confidentiality, I will not go into details. In a word, the people at the Nanjing Station of the Military Command have not been caught, and we are still in Yangzhou The National Army was robbed nearby. Although it turned out to be a misunderstanding, Section Chief Nakano and I were both robbed and taken to a place called Nangao Village.
Of course, the national army also robbed a ship of ballast salt.
Having said that, I want to explain what ballast salt is? Why do ships need to have ballast salt?
When an empty ship travels on the Yangtze River, the draft is too shallow and there is a risk of capsizing in strong winds and waves. Therefore, when an empty ship travels on the river, its carrying capacity must be increased.
In the past, people used ballast stones, but this has the disadvantage that it is troublesome to transport and has no economic value.
Li Yuewang, the captain of the Jianglong, was very smart and used salt instead of stones. There are two advantages. One is that it is easy to carry. The salt bag can be carried on the shoulder and left without anyone lifting it or any equipment; the other is that when it comes to loading, At the location, you can sell the salt to make money. After returning, after selling the goods, you can buy some salt for ballast. This cycle continues, turning the act of ballast, which has no economic value at all, into a business. I have to say ,Li Yuewang is really smart."
Having said this, Lin Chuang felt a little thirsty and glanced at his tea cup.
Fairy Shigong was very clever and quickly stood up and brought the tea cup to the "lecture table".
"Thank you." Lin Chuang thanked him and took a sip.
Put down your cup and continue talking.
"The ballast salt was robbed in Yangzhou, so Li Yuewang had to buy salt in Yangzhou to replenish it. There was no way, it was unsafe to sail without it.
By chance, because we had other things to do, Section Chief Nakano, Kameda and I went to Nanjing for a business trip and then took the train back to Shanghai.
Hua Yichang, Ye Ziqiong, Liu Deshan and the three surveillance agents continued to return to Shanghai on the Jianglong.
The next day, before I could rest, I heard the news that six people had been murdered.
I'm thinking, Section Chief Nakano and I are really lucky. If we hadn't left the Jianglong on business, would we have been killed at this time?"
As soon as Lin Chuang said this, Nakano Yunzi tensed up and thought, "Don't tell me, it's really possible."
"Okay, now that we've talked about the general background, let's talk about this case."
Lin Chuang changed the subject and began to introduce the case: "The first thing I arrived at was the death scene of Liu Deshan and three agents.
Soon, I discovered three doubts.
The first doubt is the smell of the scene.
At that time I smelled a pungent smell, much like rotten eggs.
I didn’t think too much about it at the time, because the bottom compartment was relatively tightly closed, the ventilation was poor, and there were a lot of dead fish and shrimps on the boat, so it was understandable that the air smelled bad.
However, upon inspection later, it was found that apart from salt, there were no dead fish or shrimps in the bottom tank.
Where did this stench come from? Is it directly related to the deaths of the four people?
The second doubt: Why did four people appear in the bottom cabin?
Please look at this picture. Liu Deshan and the other three people died one after another, and the next three people all stretched their hands forward. What does this mean?
Regarding this doubt, when I saw the wound on Liu Deshan's chest, I felt that there was a reasonable explanation.
Liu Deshan's injuries were torture injuries. Because he left in a hurry, he was not treated properly. Therefore, Section Chief Nakano and I heard Liu Deshan's painful screams.
Can we understand it this way? Because Liu Deshan’s wound was suppurating, he thought that salt has anti-inflammatory and analgesic effects. So when he was in unbearable pain, he thought of ballast salt? So he appeared in the bottom cabin late at night?
After having this inference, we can push forward along this inference.
When Liu Deshan came to the bottom cabin, he lost his mind and was poisoned to death.
As for the conclusion that the four people died of poisoning, it was drawn based on the circumstances at the scene.
There were no bullet holes in the bodies of the four people, so they were obviously not shot. Combined with the pungent odor, it is not difficult to conclude that they were poisoned.
Although the Xilin forensic doctor did not find any poison, he also concluded that he died of poisoning.
Okay, let's proceed with the inference.
The agent in charge of surveillance discovered that Liu Deshan had reached the bottom cabin and was lying motionless on the salt bag. He then tried to pull him up, but was also poisoned. It was easy to explain that the two men who followed him could not see their companions. They found the bottom one after another.
In the cabin, after finding their companions lying on the salt bags, they all tried to pull them out, but unfortunately they were hit.
This can also be proven from the autopsy results of Xilin Forensic Doctor.
The autopsy report said this: Liu Deshan's death time was between 12:30 and 2 a.m. The three Japanese agents died at different times. The first death time was between 12:45 and 1 a.m.
The second person died between 1 a.m. and 1:30 a.m., while the third person died after 3 a.m.
The third doubt: What poison was in them?"
Having said this, Lin Chuang glanced at Xilinling and saw that the eyes of the forensic doctor were bright and clear, and he obviously wanted to know the answer.
So he smiled slightly and said: "I didn't understand it at first. Later, when I interrogated Lu Shutao, he said that he graduated from the Department of Chemistry of Waseda University in Japan. The word chemistry reminded me of the smell like rotten eggs in the bottom of the tank.
, isn’t it the smell of hydrogen chloride? Xilin, have you heard of hydrogen chloride?”
"Sir, I've heard about it." Xilinling stood up and replied.
"Okay, please sit down." Lin Chuang motioned for him to sit down.
But instead of sitting down, he asked very impolitely: "Sir, I have a question, where does the hydrogen chloride come from?"
