Wan Lilang looked at Lin Chuang with eyes full of curiosity.
"Deputy Director Li, do you still remember Lu Shutao?" Lin Chuang asked Li Shiqun.
Li Shiqun thought for a while and said: "Of course I remember the military commander, the one who killed Hua Yichang, Ye Michelle and Liu Deshan."
"Yes. When I solved that case, I learned some chemistry knowledge." Lin Chuang said.
Li Shiqun nodded and said, "Especially the chemical knowledge about killing, right?"
Lin Chuang choked.
In fact, the limited knowledge of chemistry was what Lin Chuang had learned in his previous life, and he did not deliberately learn it at all.
Although Li Shiqun's words were not without malice, they were also true.
As an "anti-special" person, if Lin Chuang wanted to learn, he would definitely learn the knowledge of killing on purpose, or develop killing skills from the knowledge he learned.
Therefore, Lin Chuang did not intend to deny it, so he solemnly said: "What you said is true. However, learning the knowledge of killing does not necessarily mean killing people. You can also use it to solve crimes. At least until now, I have not used the knowledge of chemistry
I have killed someone, but I have solved a major case, and now I am using what I have learned to solve the case."
"Hmph." Li Shiqun snorted softly in his nostrils but said nothing.
"Whether I will use chemical knowledge to kill people in the future, that's really not certain. I hope some people don't offend me, especially those who have ill intentions towards me. I will kill people invisible." Lin Chuang squinted at Li Shiqun's words.
He snorted coldly and gave a tough response.
"Director Lin, are you threatening me?" Li Shiqun asked with a sharp gleam in his eyes.
"You don't dare. You, Deputy Director Li, are public-minded and have no hostility towards me, Lin. How could I use this method to deal with you?" Lin Chuang said coldly.
Wan Lilang saw that the two of them were getting more and more tense as they talked, so he quickly made a round.
"Mr. Lin, Deputy Director Li didn't mean that. I thought you had misunderstood. As a counter-agent, it's not strange to learn the knowledge of killing. For example, we all learn to shoot, but the muzzle of the gun is never pointed at our own people. We kill the enemy.
Well."
"What Director Wan said is absolutely true, but I'm afraid some people don't think so." Lin Chuang had kind words for Wan Lilang.
"Then, Chief Lin, continue?"
"All right."
Lin Chuang responded, turned away from Li Shiqun, and said: "As far as I know, when vinegar and baking soda are mixed together, a violent reaction will occur and a large amount of carbon dioxide will be produced. Carbon dioxide is not a poisonous gas, but if it is in the air
If the concentration of carbon dioxide is too high, it will cause suffocation."
"So, Chief Lin suspects that after Chen Yifei, Hu Yafu, and Tian Chun were suffocated by carbon dioxide first, the murderer then entered the room to break the lock and kill people?" Wan Lilang asked.
Lin Chuang nodded: "And Liu San. After he fell asleep last night, he didn't get up uncharacteristically. He also said that his head was dizzy, which may have been caused by high carbon dioxide concentration."
Wan Lilang thought for a while, and finally agreed with Lin Chuang's statement, but asked another question: "Sir Lin, we have vinegar, but where is the baking soda?"
"Here, that's the jar." Lin Chuang replied, pointing to the jar containing alkaline noodles.
Wan Lilang went over, picked up the jar, put it in the yard, squatted down, opened the lid, looked at it, and asked, "It looks like alkaline noodles. Sir Lin, will vinegar and alkaline noodles be mixed together to produce carbon dioxide?"
"No." Lin Chuang replied.
"That……."
"When I came to investigate in the morning, Wu Zhongcheng also said it was alkaline noodles, but now I suspect he was lying. It should be baking soda."
"What's the difference? Do you want to try mixing it with vinegar?"
"What you said is also a method. But there is also the simplest way to distinguish."
"Please advise."
Lin Chuang said: "Director Wan, please send someone to find some alkaline noodles, and get two glasses, and put half a cup of water in them."
"yes."
Wan Lilang agreed and arranged for his men to handle it.
Soon, alkaline noodles were found and two and a half cups of water were poured.
Lin Chuang said: "Alkali noodles and baking soda are not visible from the outside, but alkali noodles are easily soluble in water, while baking soda is not easily soluble in water at room temperature, and will also produce crystals. Director Wan, please pour the two separately.
Put some in two water glasses and you can tell the difference."
Wan Lilang did as he was told and found that the alkaline noodles he brought quickly dissolved with water, but the "alkali noodles" taken out of the jar were not soluble at all and had some crystallization.
"Sir Lin, your judgment is correct. Wu Zhongcheng is indeed lying. This is baking soda." Wan Lilang said excitedly.
"Okay, find another basin, first pour in baking soda, and then pour in a bowl of vinegar, and let's see what the effect is." Lin Chuang ordered again.
One of Wan Lilang's subordinates was very obedient and went to the kitchen to get a basin without waiting for Wan Lilang's order.
Wan Lilang did it himself, grabbed a handful of baking soda from the jar and put it into the basin, then lifted the jar and poured half a basin of vinegar into it.
I saw a large amount of bubbles instantly generated in the basin, and the basin was submerged in the blink of an eye. At the same time, a stream of colorless and odorless gas rushed into the noses of the onlookers, making them choke and unable to breathe.
Wan Lilang, who was closest, had no time to dodge and was choked so much that he staggered back. Jealousy Tanzi almost let go.
What else can you say? Facts speak louder than words.
Li Shiqun looked very unhappy, but he still asked without giving up: "Since carbon dioxide is a gas, it can't be held in your hands or put in your pocket. I would like to ask Director Lin, how did Wu Zhongcheng get it into No. 3? You can
Don’t say that he came there with a vinegar jar and jar.”
"This is simple. He must have made it at home, collected the carbon dioxide in a container, and then carried the container over."
"What container?"
"Food pocket."
"Food pocket?"
"Yes. Director Wan, please take out those two noodle bags."
"yes."
Wan Lilang went to the kitchen and took out two noodle bags and handed them to Lin Chuang.
"In order to prevent flour from seeping out from the surface of the bag, the material of the flour bag is very fine. Although it is not completely without gaps, it is more than enough to hold carbon dioxide, and there will be no major leakage.
Don’t you believe this? I grew up in a rural area. When I was a child, I often went to the river. Before I learned how to swim, we often took off our pants, tied the two corners, then buttoned them hard, and then tied the waist of the pants.
, it was made into a simple lifebuoy, which we call a trousers float. If you lie down on the trousers float and flap your head, it will not deflate even in the weather.
There was a man in our village called Mao. He was digging in the field at noon. There was an earthen well in his field. He fell into the well while walking backwards. Because it was noon and there was no one else in the field, he
It was useless to shout for help. He used this method to make a trousers float and persisted until people were working in the fields, and then he was rescued," Lin Chuang said.
After listening to Lin Chuang's explanation, everyone nodded and expressed their belief.
Only Li Shiqun was dissatisfied: "That's not feasible, it's far-fetched, and there are still questions..."
