In the middle of the night, Ning Zhiheng edited the telegram and reported the arrest of Zou Chengbin to the headquarters, and let the bureau screen it by itself.

Early the next morning, Ning Zhiheng took Yi Hua'an out of the Huiying Hotel, and after confirming that no one was following him, the two of them acted separately, Ning Zhiheng came to Taishan Road in the city, and found an inconspicuous small hotel and opened a room not far from the Buli coffee shop.

At noon, Yi Huaan also rushed over, carrying a large suitcase in his hand, knocked on the door and entered the room, carefully placing the suitcase in his hand on the table.

Ning Zhiheng first closed the door carefully, then turned around and asked, "Are you all ready?" ”

Yi Huaan nodded and said: "According to your list, everything is ready, but yellow phosphorus is not easy to handle, I went to the vicinity of the two match factories for a long time to find one of their warehouses, and bought off the guards with a lot of money, so I got this." ”

Ning Zhiheng came to the window first, stretched out his hand to push open the window, it was the cold winter time, the temperature in the room was not high, the cold air outside poured in along the window, the room suddenly became cold, and after a while, the temperature in the room was about the same as the temperature outside.

At this time, Ning Zhiheng came to the suitcase, gently unfastened the leather buckle, lifted the lid of the box, and took out all the items inside.

A few thick pieces of cotton cloth, two bottles of fine kerosene, and finally a small flat leather case half a foot square.

Yi Huaan hurriedly reminded on the side: "Be careful! ”

Ning Zhiheng took a closer look at this delicate little leather case and asked, "How is the sealing of this box?" ”

"I went through several shops to choose this box, which was a good size and had a good seal, but it was impossible to completely isolate the air."

"That's the best!"

Ning Zhiheng nodded, took out this small suitcase separately, put it in front of him, unfastened the leather buckle and opened it gently, inside was a tightly wrapped plastic sheet, through which it could be seen that there was a large piece of solid like yellow wax inside, which was yellow phosphorus.

Ning Zhiheng nodded slightly, turned to Yi Hua'an and said, "You go to the alert, I have to do some experiments." ”

Yi Huaan agreed and retreated, Ning Zhiheng felt that the air temperature in the room was already very low, so he spread out a piece of cotton cloth, poured some kerosene on the cotton cloth, slowly soaked it through, and then opened the plastic sheet, revealing the yellow phosphorus inside, took out a small piece from it, put it on the cotton cloth, raised his hand to look at the time, and slowly observed.

Time passed quickly, and in the evening, Ning Zhiheng ended the experiment in his hand, and the test results verified that his idea was completely feasible, he saw that the time agreed with Xu Yongchang was almost up, so he cleaned up the house, put the suitcase in his hand, and pushed the door out of the room.

He walked out of the hotel, walked a distance, came to the door of the Bully coffee shop, and turned his head to look at Yi Hua'an, who was in charge of guarding not far away, Yi Hua'an nodded to Ning Zhiheng and signaled safety.

Ning Zhiheng pushed the door in, asked the manager of the coffee shop for a private room, two cups of coffee and some refreshments, and quietly waited for Xu Yongchang's arrival.

It didn't take long for Xu Yongchang to come quietly as promised, Ning Zhiheng signaled hello at the door, and Xu Yongchang hurriedly followed Ning Zhiheng into the private room.

After closing the door and sitting opposite each other, Ning Zhiheng asked in a low voice, "Has the situation changed?" ”

Xu Yongchang shook his head and said: "There is no change, Li Zhiqun has informed us to get ready, tomorrow at eight o'clock in the morning, the special high school will arrange a vehicle to send us to the airport, and at the same time, Fu Shengyuan and his wife will also return to Shanghai with the trip, it should be around half past eight to board the plane." ”

Ning Zhiheng calculated the time for a while, felt that there was no problem, and said in a deep voice: "I decided to completely solve these traitors on the way back this time, and I will do something on the plane they are on." ”

Speaking of this, Ning Zhiheng put the suitcase on the ground on the dining table, opened the lid of the box, pointed to the items inside, and began to say: "The yellow wax-like thing in this plastic sheet is what we often call yellow phosphorus, and it is also the key to our operation. ”

Next, Ning Zhiheng carefully introduced the characteristics of yellow phosphorus, which is a chemical that is a raw material for making foreign fire, and it is also a highly toxic chemical, its biggest feature is that it has a low ignition point, and it can burn itself at a room temperature of thirty or forty degrees.

Moreover, the yellow phosphorus burns very fully, and the maximum combustion temperature can reach more than 1,000 degrees, so as long as the material that the flame touches, it can basically be burned and turned into fuel, resulting in the fire burning bigger and bigger, especially in the narrow space, the danger is greater, and the heat released is enough to destroy all organisms within the effective range.

When the burning yellow phosphorus comes into contact with the human body, the skin will be penetrated, and then penetrate deep into the bones, which cannot be extinguished at all until the human body is burned to ashes.

In addition to temperature, there is also a prerequisite for the spontaneous combustion of yellow phosphorus, that is, it must be exposed to the air and react with the oxygen in the air before it can spontaneously combust.

Therefore, the conditions for the preservation of white phosphorus must meet two conditions, one is that the temperature is lower than the normal temperature and cannot exceed the ignition point of white phosphorus, and the second is to isolate the air, and it can even be stored in water.

Because of the urgency of time, Ning Zhiheng couldn't find the raw materials for the explosives for a while, and finally thought of using yellow phosphorus to set fire, because this raw material is the best to get, and because the power of yellow phosphorus is huge, once it burns in the air, there is no way to extinguish it, and it is inevitable that the plane will be destroyed and people will die.

After Ning Zhiheng introduced the characteristics of yellow phosphorus, he continued to carefully advise: "This package of yellow phosphorus has been sealed with plastic sheeting, isolated from the outside air, and it is winter now, and the temperature is very low, so it is not enough for spontaneous combustion, and it is safe for the time being."

After you bring it back, try to place it at the window or on the outdoor balcony, so that the air outside is low and safe.

Before going out tomorrow, cut the plastic sheet with a dagger at low temperatures, be careful not to touch the yellow phosphorus with any part of your body, and then wrap the outer layer of the plastic sheet with a cotton cloth soaked in kerosene, remember, be sure to wrap two layers of cotton cloth, so that you can continue to isolate the air, and then put it in this small suitcase.

This suitcase is very well sealed and can control the smell of kerosene, but it cannot completely isolate the air, so it does not affect the combustion of yellow phosphorus.

When he arrived at the airport, he took the opportunity to put this suitcase on the plane that Fu Shengyuan was on, emphasizing that Fu Shengyuan must be the primary goal, and he would put it on which plane he took. ”

Speaking of this, Ning Zhiheng then took out a sketch, which was the internal structure of the aircraft he had drawn in advance, pointed to one of the points and said: "The structure of Japanese planes is roughly the same, this position in the cabin is closest to the engine, when the plane is running, the temperature here will be the highest, if it is a passenger plane, there should be a compartment for luggage, you have to put the suitcase into the compartment, after a period of time, the temperature of this compartment will definitely reach the spontaneous ignition point of yellow phosphorus." ”

Xu Yongchang asked suspiciously: "The burning temperature is enough, how can it be exposed to air, it can't burn without air?" ”

Ning Zhiheng couldn't help but smile proudly, the next step, this is what he racked his brains to design.

He pointed to the two bottles of kerosene and said: "This is the use of these kerosene, yellow phosphorus is not compatible with water, but it has a slight fusion with kerosene, that is to say, if you use cotton cloth soaked in water to wrap yellow phosphorus, then you can completely isolate the air, but the use of cotton cloth soaked in kerosene can only play a role in temporarily isolating the air, after a long time, the yellow phosphorus in it will gradually merge with kerosene, and slowly soak into the surface of the cotton cloth along the kerosene, so as to contact with the outside air."

At this time, I experimented, wrapped in two layers of cotton cloth soaked in kerosene, the time for yellow phosphorus to fuse kerosene was about an hour, and when it seeped out of the surface of the cotton cloth, it should be about an hour and twenty minutes.

In this way, the temperature of spontaneous combustion has been reached, and the oxygen in the air has also been contacted, and it will burn on its own, and the amount of yellow phosphorus in it is sufficient, once ignited, the heat released can ignite the solid wood and leather in the aircraft shell in a short time, and because it is insoluble in water, it cannot be extinguished even with water, and the fire will even burn bigger and bigger, the space on the plane is narrow, and the people on it can only sit and wait for death, and the plane is destroyed and people will die, and the chance of survival is very small! ”

At this time, Japanese planes were all aluminum skin, that is, the outermost layer was aluminum, and the inside was leather and solid wood, if the extremely high temperature flame burned from the inside, the plane would soon be burned to only one shell, and even the shell could not be kept in the end.

Ning Zhiheng painstakingly designed this set of procedures, believing that as long as there were no accidents during the trip, Li Zhiqun and others would not escape death.

After Xu Yongchang listened, he carefully digested every step of Ning Zhiheng's instructions, especially the points that needed to be careful, Ning Zhiheng knew that Xu Yongchang had no chemical knowledge, and deliberately explained it twice, until he confirmed that Xu Yongchang understood, and then ended the explanation.

Ning Zhiheng finally instructed again: "You remember, if there is an accident during the operation, such as a security check, or you can't board the plane, or even delay boarding, don't hesitate, immediately give up the action plan, find an opportunity to discard this suitcase, take your personal safety as the first priority, and can't force it to continue, are you clear?" ”

Ning Zhiheng has great expectations for Xu Yongchang, in addition to Xu Yongchang's value will become increasingly important in the future, that is, he is unwilling to risk the lives of his subordinates, which is also an insurmountable bottom line for him, since he came to this world, he has never given up any relatives, friends and comrades-in-arms around him!
