No trace of espionage

Chapter 785

Lin Chuang didn't answer immediately, stood up, took out a piece of white paper from his briefcase, rolled it into a finger-thin cylinder, glued it, tilted it at 45 degrees, and lit the upper end of the paper cylinder with a match.

A strange phenomenon happened, the smoke produced by the combustion did not go up, but flowed out from the outlet at the lower end.

When Quan Yangjian saw it clearly, Lin Chuang put the paper tube upright again, but the smoke came out from the top of the paper tube again.

Quan Yangjian was not an idiot, he was already in a daze before the paper tube was burned out.

"Advisor, do you understand?" Lin Chuang asked as he threw the paper tube away.

"Lin Sang, is this the principle of backflow incense?" Quan Yangjian asked.

Backflow incense, also known as downflow incense, is named after agarwood incense is ignited in a special backflow furnace, so that the smoke produced during the combustion process flows from high to low like water.

"Yes, this is the principle of backflow incense. Because the upper end is ignited, the temperature rises, the air inside the paper tube is thin, and the outside air will generate a downward pressure on the smoke generated by combustion. If the paper tube is upright, Then the chimney effect is formed, and an upward pulling force will be generated. This pulling force is greater than the pressure generated by the external air on the internal air, so the smoke will run upwards; will flow backwards."

"Hiss..., Lin Sang, do you want to tell me that someone used this method to murder the general?" Quan Yangjian asked in a trembling voice.

"Yes, although there is no evidence, I'm sure that someone is implementing this method." Lin Chuang said with a sullen face.

"Please tell me." Quan Yangjian looked at Lin Chuang eagerly.

"Your Excellency, I am an outsider, and it is really inappropriate for me to participate in your internal strife. No matter whether my judgment is correct or not, I will definitely get myself into big trouble. If it is not because of your wealth, life and family honor, just now I won't say these words either. So, please understand my difficulties, and I don't want to say anything else." Lin Chuang said.

"Lin Sang, the reason why you told me these things must be for my own good. I deeply understand your friendship for me and understand your difficulties. Please rest assured, I swear to the spirit of my late father, from now on, I will treat you like a brother, and as long as there is anything that is not good for you, I will never tell you. If you break this oath, the spirit of my deceased father will never be at peace!"

Having said that, Quan Yangjian stood up and bowed deeply to Lin Chuang: "Lin Sang, please trust me, please."

This oath is a bit heavy.

Lin Chuang didn't want him to swear, the key point was that he was really afraid that he would become a victim of their internal struggle.

Since he decided to speak out, he had already thought about the outcome, even if something went wrong, he wouldn't have any major problems.

Of course, he is not only thinking about Quan Yangjian's wealth and life, but also has his own selfishness. He wants to use this matter to unravel the truth of Qu Rubing's case and complete the task of stealing the secret code.

Even if he doesn't swear, Lin Chuang will tell him the clues he found, and his real purpose is to make the Japanese mess up.

Lin Chuang quickly stood up, saluted, and said, "This is too serious, Lin can't stand it. Please sit down, let's sit down and talk."

"Lin Sang, please tell me the whole story." Quan Yangjian sat down and begged in an almost pleading tone.

"Since Your Excellency the Advisor has made a heavy oath, I will go all out." Lin Chuang said with emotion.

"Thank you, thank you." Inuyang Jian thanked repeatedly.

"Advisor, according to my judgment, there must be Koji Baba who is directly involved in this matter."

"Koji Baba?"

"Yes, I found six suspicious points on him.

First, Nakano Nakazuo and I came out of your office that day and immediately held a meeting with Baba Koji and Shigong Fairy Shaozuo.We first determined the security principle of internal tightness and external looseness, and then when dividing the work, Nakano should have assigned the task, but the strange thing is that Koji Baba volunteered to take charge of the internal security of the Hamilton Building, and let Major Shigong Responsible externally.

Although I felt a little strange at the time, I didn't think about it elsewhere, thinking that he had a positive attitude towards work.

Second, on the issue of heating, Nakano Nakasa and Baba Koji had a disagreement. Nakano Nakasa said that burning charcoal was in line with the Japanese living habits, while Baba Koji firmly opposed it, saying that burning charcoal was unhygienic and advocated burning coal.However, Zhong Zuo Nakano believed that burning coal is prone to coal poisoning, so he disagreed.

Maybe Koji Baba's attitude was too firm, so Nakano Nakasa went to me and asked me what I could do.I gave her an idea to burn coal, but not in the general's bedroom, so that even if coal poisoning occurs, it will not pose a threat to the general's safety.

This idea was finally appreciated by Nakano Nakazusa, and at the same time, Baba Koji also agreed.

There is a question here, why does Koji Baba firmly oppose burning charcoal?Why did he stick to his point of view when his superiors disagreed with burning coal?
Thirdly, Koji Baba and I had another disagreement about which room to burn the stove.He strongly suggested that the coal stove be placed in the room directly below, that is, 416. I disagree. My suggestion is to place it in 616, directly above 516.

My reason is very good, because the water circulation is better when it is going up, but the water circulation effect is too bad when it is going down.

It was precisely because of my good reasons that Nakano Nakazuo decided to do as I said.

I noticed then that Koji Baba was disappointed.

Fourth, after deciding to put the coal stove in 616, I left and went to the Gendarmerie Command to discuss with Lieutenant General Miura Saburo the cooperation of the paper factory. I wanted him to open the gap in the army's logistics.Regardless of this, the key point is that I saw Koji Baba's car at the headquarters, and I also saw Yinhe Tanaka sending him out.

Fifth, on the second day, you and the head of the agency called me to the building because of the controversy caused by Koji Baba.You don't advocate sealing the entire east wall, but he wants to seal it.

Sixth, when I was going upstairs, I saw a few people carrying a metal tube, about six or seven meters long. At that time, I felt very strange, thinking that it was used for installing chimneys in other rooms, but now I think it is definitely not, but It is on the east wall of bedroom 516! "

"Do you mean to say that Koji Baba's strange movements are for the purpose of installing the iron tube at the upper and lower corners of the east wall, the upper end of which is connected to the coal stove, so that the coal poison produced by the coal stove can flow down, in order to cover up This tin cylinder, so he advocates sealing the entire wall?"

"Other than that, there is no other explanation."

"Also, why is it suspicious that he went to see Yinhe Tanaka?"

"It's very simple. He advocated burning coal at the beginning. He definitely wanted to use the function of the chimney to draw the wind and exhaust the poisonous smoke to the general's bedroom. Therefore, he advocated installing the coal stove in 416. After being denied by me, he felt that he was originally The plot I devised couldn’t succeed, so I rushed to ask Tanaka Yinhe for advice.”

"Tanaka Yinhe? Does he understand the principle of backflow incense?"
