What the hell is going on? Is Dr. Liu's hunch accurate? Usually a good detective like him usually has a good hunch, so how am I going to deal with these things happening—these days, I've been thinking about these questions.

Dr. Liu has already discussed with me N times about the way we escaped, especially when they sprayed the Ecstasy mist again, how I could hold my breath and jump up in the shortest possible time, and use what I had learned during this time to control them...... This is so difficult, because I don't have any actual combat experience, and although I have practiced the fighting movements thousands of times, it is still on paper after all.

We have also discussed the other option many times. Dr. Liu prefers this option, and I feel that this option is more certain. Especially now, I am very confident in the instantaneous attack and grasping the object, and I have done at least hundreds of thousands of times in that practice movement...... I even thought that if there was surveillance, I wouldn't even be able to capture the moment I attacked, because it was so fast.

……

"Gao Yue!" Dr. Liu was calling me.

"What's the matter? Physician. I asked.

"You're tired from practicing today, aren't you?" He said.

"yes...... But I can still bear it, get some sleep, and tomorrow will be alive again. I replied.

"Your current physical fitness can reach the level of a barracks soldier, but the knowledge you have learned in your head is really not less than theirs! Today we're going to talk about disguise and tracking! Physician Liu said.

"Transfiguration and stalking?! Great...... "I'm in high spirits."

"Let's talk about the disguise technique first, the so-called disguise technique, that is, the makeup technique. Because our human skin is not made of clay, it is impossible to completely change the face. Even if you have to change it as a last resort, it is difficult to bear plastic surgery again and again. Therefore, make-up does not require a complete change of face, such as putting a pillow on the back or walking in a roundabout; A slight change in the length of the hairstyle, or a well-made wig and the use of glasses, can achieve great results...... In addition, changing or eliminating features such as walking posture, black moles, and beards can completely change the impression...... Gao Yue, you have to remember that ordinary, unobtrusive costumes are also very clever masquerade, and if you dress up too eye-catching, you will lose the meaning of makeup. In addition, everyone usually does not have any curiosity about the appearance that they are accustomed to, and the uniform is one of them, whether it is a police officer, a courier or a security guard, it will not attract attention when walking. It's the same with school uniforms, and if there's a male high school student walking down the road, people would never think it's a young private detective agency in disguise and stalking ......people," Dr. Lau said.

"Oh...... It's the first time I've heard of so much exquisiteness! "I was amazed.

So, what kind of occasion do you have to wear makeup? For example, when going out to a particular social situation, be sure to ...... For example, there is a kind of area where there is a concentration of part-time workers, where there are many runaway women and men who are far from home, and this is a group of people who don't want to talk about the past, and they gather like fallen leaves. It is difficult to carry out any investigative work in and out of such a place without wearing the same clothes as them. For example, if you wear a smart suit and an expensive watch, probably no one will be willing to talk to you intimately...... On the contrary, dressing up as a laborer and entering a high-class club will also suffer the same result! Detectives are required to be suitable for the appearance of the subject of investigation at any time, so the study of masquerade should be studied by heart! Dr. Liu continued.

"In fact, we can have a variety of changes to our appearance, the first is to change the face, for example: holding a large ball of cotton in the mouth to make the cheeks appear more prominent, you can change the contour of the face; Wearing dentures will protrude under the nose and change the shape of the face...... Use skin-tone tape to hang or droop the corners of the eyes; If you trim the hairline of your forehead with a safety knife slightly, you will feel a difference. Also, as for the hairstyle mentioned above, you can change it at will as long as you use a high-quality wig. Oh yes, past experience has shown that the eyes are the least easy place to deceive, but today, due to the development of contact lenses, even the color of the eyeballs can be changed at will, and it has lost its importance. The color of the eyeballs of Europeans and Americans is varied, blue, brown, green, and black, which is different from the single color of the Easterners. Therefore, there are very few people who can clearly remember the color of the eyeball. The dialogue in the novel, 'Your eye color is so beautiful', often appears in European and American literature, but never in Chinese works! Physician Liu said.

"yes...... Makes sense! I responded loudly.

"In addition, the body shape has changed, and in terms of height, you can increase your height by more than five centimeters as long as you wear high heels, but when you want to appear shorter, even if you bend your back, you can only reduce it by five or six points, and it will look very unnatural if you exceed this limit...... Gao Yue, you have to remember that too extreme fraud will be counterproductive! He continued.

"Uh-huh...... I remembered. "I answered.

"Walking with your knees slightly bent in baggy trousers is also an option. The width of the bust and shoulders can be changed with clothing. When a man dresses up as a woman, he must be careful not to reveal the habits of a man...... The way you walk should be changed. Usually women walk in the figure of eight, and the stride is not very large; But the male is the outer figure, and the pace is larger. If you run, your feet will be exposed...... Hee-hee. Dr. Liu smiled.

"When you used to handle cases, did you often disguise yourself as a man? Still often showing the horse's feet? I laughed.

"I was spotted once...... Just once, because I was in too much of a hurry, I chased after it and was seen by another guy, haha...... However, we succeeded in the end! Just a small episode...... Now I'll use it as a lesson to teach you! Hee-hee...... Dr. Liu laughed.

"Before I explain the tracking technique, let me briefly tell you some common sense, you have to remember." Dr. Liu continued.

"Well, that's what I like to hear!" I laughed.

"In addition to the observation method that we have told you before, the most important thing is the interpretation technique. For example, when talking to the other person, we must listen to the clues, otherwise we will lose our qualification to be a detective...... In order to master the art of interpretation, it is necessary to do the following: first, in order to gain the trust of the other party, speak politely to the other party; Second, instead of being able to speak, it is better to listen...... Third, if the other person has a cat or dog in the house, don't let it go...... Because cats and dogs speak the words of their owners...... You know that, right? You've got a lot of pet rats now! Don't think I don't know......" Dr. Liu smiled.

"I can't hide anything from you!" I laugh too.

"The fourth aspect is to skillfully ask the same question in different ways, and to confirm the facts through more than two interviews...... Also, in front of the opponent, you can't take out a note to make a record, which will make the opponent wary. Therefore, just ask questions verbally and keep everything the other person saying in your head; Sometimes even if the other party complains, or talks about his life experience and situation, he must listen tirelessly like a relative; By the way, you should try to match the personality of the other person and change the technique of conversation...... Now, I'm going to give you a few more details about these seven aspects......" Dr. Liu continued.

Dr. Liu knows so many things, and these are all valuable experiences that have been gained through his practice, and I must learn them well...... I made up my mind.
