The next day, we continued to train as planned.

In the morning, it was still a warm-up exercise and a bottle grabbing training in the air, but my muscles were sore, and the 365 laps were fine, but those push-ups were really terrible, and my arms hurt so much that I managed to complete the task. Dr. Liu told me that if I persisted, about the fifth or sixth day onwards, after the soreness disappeared, I would usher in another realm.

In the afternoon, I still repeated the basic postures, hand shapes, step patterns, and footwork of hand-to-hand defense and counterattack, although it was boring and monotonous, but I knew very well in my heart that these most basic things were laying the foundation, and only when the foundation was firmly laid could I proceed to the next step of learning and improving. I remember watching movies before, those little monks of Shaolin Temple had to learn to stand for half a year.

In the evening, Dr. Liu gave me a serious lecture on how to train and improve my observation skills. Before I got into that, a question popped into my mind.

"Doctor, it suddenly occurred to me just now that Qin Lingjin has completely replaced my life, what about his own life? Suddenly, in this world, he disappeared for no reason? Isn't there anyone who doubts it? Also, when I met him, I never met his family......"

That's a good question...... I've thought about it before, too. I guess he must have lied to his family and made him disappear for a few years and then ......," Dr. Liu replied.

"Huh? And then what?! "I was shocked.

"You guessed that, right?" Physician Liu said calmly.

"Could it be...... He's going to wait for the time to come, kill me, and throw me somewhere, causing an accident, and then ...... I'm going to be a substitute for the dead?! I asked, horrified.

"Yes! That's why...... The reason why he doesn't kill you now! Doctor Liu said word by word.

"Oh my God, this ruthless guy!!" I couldn't be furious.

"He will kill you first, and then create an accident scene, such as a traffic accident, the vehicle catches fire and explodes, he will find a way to make your fingerprints and other physical characteristics unidentifiable, but there are Qin Lingjin's ID cards and other objects nearby...... Let the world know that Qin Lingjin died in that accident! Dr. Liu exclaimed.

"And he...... It's always me!! I roared.

"That's right! So...... We really don't have much time left! Physician Liu said.

"Now is not the time to be angry, Gao Yue, clean up your feelings. Let's keep training! That's the most important thing! He continued.

I gritted my teeth, tears of anger in my eyes.

……

After a long time, I calmed down. He continued:

"I'll tell you about observation...... Do you know how we used to develop elite observation? That's called devilish training! When I think about it now, I feel a little ......."

"Hmm...... Doctor, can you be specific? I asked.

"Good...... Let me tell you about our detailed observation and training plan in the past, which is generally arranged for a month as a training stage, and our instructors usually choose the training location in the station, airport, large shopping mall and other places where there are many people, and I remember another time, even arranged in the detention center, where it is more conducive to observing the appearance and demeanor of all kinds of criminals. The way of training is according to the worker, which can be divided into factory workers, water and electricity maintenance, telecommunication line maintenance, cleaners, porters, etc., according to individual needs...... Farmers, soldiers, policemen, civil servants, businessmen, professionals, including lawyers, accountants, journalists, advertising planners...... According to the standards of business personnel, one or two people are selected as 'models', and their physical characteristics (height, face, hairstyle, posture), clothing, talking or meditating with others, demeanor during rest, and habitual movements are recorded one by one, and the description should be as accurate and expressive as possible. Without causing trouble, you can also use the camera to photograph these 'models' in different occasions and situations. Every night when I go back, I will revise the record according to the photo until I am satisfied with it! Persist in this way for two or three months, when there are no less than 20 people in each category and the total number of recorded 'models' reaches more than 1,000, then you can carry out inductive analysis! Dr. Liu exclaimed.

"So complicated?" I asked, surprised.

"yes...... According to the self-defined categories, all kinds of people are classified into a table when they are talking, walking, shopping, and resting, so that they can gain a certain understanding of the appearance, dress, and demeanor of people with different identities and backgrounds on different occasions! With this table, we can analyze it together with the experience of observing and recording the expressions and behaviors of thousands of people, and then contact people outside in the future, and observe and judge the occupation of the other party, it is a simple thing! Dr. Liu continued.

"This is a very scientific way of training, after a few months of devil training, it will really become very powerful!" I admire.

"After this step, it is necessary to observe the 'safety' of people. As the name suggests, a safety observation is an observation of whether the target person is dangerous to themselves or others! Gao Yue, do you often ...... When watching cop movies or detective TV series, or reading such books, you are often impressed by the accurate insight and foresight of the protagonist into danger? In real life, especially the situations we have to face, of course, it is not so suspenseful! However, it is not uncommon for more experienced police detectives or detectives to be aware of sudden danger in advance, because it is trained! There's nothing about it – it's just that we've mastered a set of practical methods of observation, and we've trained them to perfection in practice! He said.

"Master, you should be the kind of detective who can detect sudden danger in advance!" I said it out loud.

Dr. Liu paused, seeming to drink water.

"The purpose of this type of observation is to detect possible dangers at an early stage so that they can be prevented! The core of this observation is this, combined with the methods used in close quarters attacks in general, and the series of physical and psychological changes that inevitably occur when the attacker takes such an action

'Four looks': one is to look at the eyes and complexion: I remember that it was said in ancient books: the face of the brave is red, the face of the brave is white, and the face of the brave does not change! Indeed, when a person is about to attack another person (even someone who is very capable of self-defense), his adrenaline is accelerating, and his face and eyes do not change in the slightest - that is very unlikely! Therefore, staring directly into the eyes of suspicious approachers often works wonders! - If the other party has a ghost in his heart, he will either reveal it on his face immediately, or he will not dare to look you in the eyes! He exclaimed.

"yes......" I sighed.

"The second is to look at the hand: whether it is a gun or a knife, in many cases it is directly held in the hand, if a person approaches you, you can't see his hand, then it is worth being vigilant; In addition, on some occasions, even if the other party does not have a murder weapon on him, when he has unfavorable intentions against you, his hands will generally be clenched tightly! The third is to look at the footsteps: when you are in an unsafe environment, especially in the kind of small alley next to no one, if the person walking across from you, although there is no abnormality in the facial expressions and hands, but when approaching you, the steps are unusually dignified, then you have to be careful! - He's probably trying to get something out of you. Fourth, look at the waist, armpits and calves: this is mainly for the approacher who may be carrying a weapon! The detectives come into contact with a lot of people in their work, many of them are outlaws, and some are even direct enemies, for such people, there is generally not much prelude to launching an attack! Therefore, it is necessary to maintain a high level of vigilance...... From a general point of view, if the perpetrator carries a firearm, most of them are hidden in the waist and armpits! Sometimes, in order to be more concealed, if he buys a foot holster, he may also hide the gun on the foot holster! When the time comes, just crouch down and you can shoot! Knives are also conventionally tucked under the tucks or strapped to the calves! …… Once you've mastered the essentials of this type of observation, the training itself is relatively simple! At that time, when we were training in arrest techniques, there were training subjects that specialized in subduing the other party when passing by, and there were several situations, such as one person against one, two people facing one person, two people facing one person in front of the other, and two people facing one person in front and back! Because when training like this...... It is also required that the demeanor and behavior of the arresting personnel should be relaxed as much as possible! Therefore, if the detective arranges several such drills and videos the whole process, and replays it afterwards, it is very easy for him to have an understanding of the various cover-up actions and demeanors of this kind of attack, and strengthen his sensitivity in observing such scenes......" Doctor Liu said so much in one breath.

"Doctor, there is so much knowledge...... You have to teach me all this, especially to observe the danger, to rub shoulders with the enemy...... Tricks to subdue each other! I want to learn this! I shouted.
