(Don't forget the Sanjiang ticket, thank you)

Xia Qing said: "According to the report, the tip has been taken away by the waiter. That poison bill is not theirs. However, the hallway surveillance footage did not show anyone else entering the suite. And there was a bodyguard left in the room. ”

Li Qi said: "The waiter will definitely do one thing when tidying up the room. Guess what? ”

"Wash the toilet." Mi Wu hurriedly replied: "Change towels, change sheets." ”

Li Qi despised it: "Think of something useful." ”

Xia Qing's eyes lit up: "It is to open all the windows for ventilation, and the windows will be closed after the cleaning is over." Banknotes are supposed to be accessed through the window. Tinghai Hotel although there are no high-rise buildings nearby. But as long as the wind is calculated correctly......"

"Aerodynamicist?" Li Qihan said: "Think simply, and then look at the police scene investigation." ”

"Banknotes have small holes...... It was a remote-controlled plane or a kite that sent poison money into the window. ”

"Maybe." Li Qi replied.

"Then the other party is good at using poison and using simple flying machines." Xia Qing pondered: "If it were me, I would design a way for the aircraft to carry poison gas. The luxury suites of Tinghai Hotel are on the top floor, and the wind is strong, and simple aircraft may not be able to carry poison gas. In addition, there are no high-rise buildings near Tinghai Hotel, which is not suitable for attack. Changed to another hotel or villa...... However, the glass of the hotel is closed and the curtains are closed, so it is difficult for the other party to take advantage of it. ”

"A flying machine bought in a supermarket for a few hundred yuan is not good, but it is different if it has been modified. For example, the waiter cleans the suite, opens the window, cleans, sorts, and changes the sheets. At this time, the aircraft carrying poison gas and cameras flew into the suite, lurking under the bed or cabinet. When the target returns, turn on the poison gas remotely. The best part of this method is that when the body is found, the window will be opened as soon as possible, and the aircraft may be able to slip away through the window. ”

Migo asked, "Advisor, you're so good. ”

Li Qi hurriedly said: "It's completely conjecture, because I know such an assassination method." Poison banknotes may also be placed in the vent, or they may be placed in the morning, or they may be attached to the waiter's clothes by the opponent and taken off by remote control or other means. But I know that an assassin who is good at using poison is likely to stick to it. The banknote is made of cyanide, and this person's profession can guess that he has contact with chemistry, and if his profession dictates, he will also use what he is best at. ”

"Tetraethyl lead is readily available and can be absorbed through the skin and respiratory tract." Xia Qing said: "It is colorless oil and easy to volatile. There is a faint fruity scent. Gasoline contains this substance, so it's best not to wash your hands without gasoline. Once the purification concentration is high, a large amount of smoke will be produced after the catalytic and volatile agents are added, and a large amount of ingestion in a short period of time will cause acute poisoning. At the age of the dignitaries, it was basically impossible to survive. ”

Mi Wu admired: "Xia Qing, you are also very powerful." ”

"I majored in chemistry in college." Xia Qing explained: "Other chemical poisons are either difficult to refine, or need to be taken orally, or need skin contact, or are easy to rescue. ”

"Ouyang Jianlan shouldn't have the possibility of poisoning the other party's food...... Let's assume that the Assassin is using tetraethyl lead, so that the question remains, how will the other party deliver the product to the villa. The hotel was replaced by a villa, which should have been unexpected by the assassins. However, whether it is with a flying machine or by sneaking in, people need to be in the vicinity of the villa. Li Qi said: "So the next is our main job, squatting, observing and finding targets, eliminating targets, and completing a security." There are three military binoculars with night vision here, and we take turns on duty, and we move smaller, so that our own people don't find out, it's too embarrassing. I dig an observation point. ”

"Observation Point?" The two glanced at each other. …,

"An observation point is a good place to look at the terrain." Li Qi took out a portable sapper shovel and began to clear the dirt nearby. Soon an inclined plane appeared. This is a simple sniper position. Snipers need to wait for their target and ensure their physical comfort, so they need an oblique angle to lie on their stomachs. Even the chin can be used as a resting fulcrum. Li Qi took some leaves and branches to camouflage and made a small nest. As long as you don't get too close, you won't find it.

"Team Leader Ouyang is observing with a telescope." Migo returns.

"Keep your head down!" The trio wore grass-green hats that were not easy to spot. In fact, Ouyang Jianlan has ruled out the possibility of sniping, this observation is just a professional habit. The possible reason for ruling out sniping is the same as what Li Qi said.

Xia Qing said: "Consultant, talk to Team Leader Ouyang?" ”

"For professional assassins, the power of bodyguards is completely clear. Our bodyguards are confidants and do not know each other, so the assassin always has a head start over the bodyguard. I'm a very aggressive person and I've always disliked being passive. I'm dealing with manor-type security, and I'm going to set up a dark post. If it is a troubled area, the dark hill should be extended to 10 kilometers away. This will give you enough time to defend or retreat. It's not like in the movie, where the bodyguards are all operating under open fire, for fear that others won't know the location. Now ordinary people can get a mobile phone bugging device for a few hundred yuan, and the confidentiality of mobile phones is very low. Mobile phones and walkie-talkies are not encrypted, making it easy to crack. ”

"I know." Mi Wu took out his mobile phone and read a text message: "Do you want to know who your other half is talking to?" Do you want to know what text messages your significant other is sending? Do you want to know the position of the other half, only 399 ......"

……

At night, mosquitoes begin to increase. Li Qi carried insect repellent oil, which was not a trouble. The trouble is a rainstorm that can come at any time. Heavy rains in summer are often accompanied by thunder and lightning. For people who use night vision devices, the most annoying thing is the sudden thunder and lightning. Li Qi was not stingy to introduce: "Xia Qing uses the second-generation product of low-light night vision device, which is suitable for observing the terrain. Mi Wu uses infrared night vision devices, which are more suitable for seeing people. I'm a thermal imager, it's good for daytime use, and if there's lightning, you guys stop looking. ”

"Advisor, you know a lot." Mi Wu could only praise.

Xia Qing said: "Consultant, I am really sorry for eating my son last time." I have failed to live up to your expectations, and I have always wanted to find an opportunity to apologize to you and Team Leader Jiang. ”

Li Qi said: "Apologies are the last thing you need. I would like to know what was on your mind that day. ”

"Nope!" Xia Qing denied: "It's completely negligent. ”

"Really?" Li Qi changed the subject and said: "Mi Wu, have you found any suspicious people?" ”

"I think everyone is suspicious." Mi Wu replied and looked at the PDA: "Advisor, there is a new wireless signal." ”

"Cell phone?"

"Not sure, it's the source of the signal that just appeared, over there." Mi Wuyi is 300 meters from the Little White House. Tossing it for a while, he said, "It's not a mobile phone and a walkie-talkie." It is an electronic signal. ”

"RC helicopters?"

"Possibly." Migo looked at it again: "The signal is gone." ”

"I'll take a look." Li Qidao.

"Slow." Xia Qing said: "The armed guards at the gate of the villa set off towards the signal point. ”

Li Qi took the night vision device and looked at it for a while and said, "It seems that Ouyang Jianlan has also guarded against electronic raids. ”
