Transfiguration is to completely turn oneself into another person, it is a very profound disguise, and disguise is actually to cover up a person or something, the latter only needs to ensure that it is "not like", but the former must ensure that it must be "like".

In fact, there are many camouflage masters in nature, such as orchid mantis, bamboo leaf insects, etc., but they all have one thing in common, that is, they basically only camouflage static items, because in comparison, dynamic camouflage is much more difficult, and the most difficult thing is to disguise yourself as another person.

Why? Because the laws of human activities are the most complex, and everyone's life experience is different, everyone's behavior and habits are also different, even twins who have grown up together since childhood, there will be differences in details.

So no matter how a person disguises, he can't help but retain his behavioral habits, and when the situation is more tense, the more flaws there will be, and the easier it will be to expose.

Therefore, in addition to mastering the skills of disguise and the behavior habits of all kinds of people, the most important thing for a successful disguise master is to have a big heart that can maintain composure at all times.

Compared to the Master of Disguise, the Disguiser is only superior in disguise skills, and once he ignores the other two requirements, he is just putting a mask on himself.

As for the disguised Magus, he is the lucky one who treats the skill of disguise as instinct, but unfortunately because he relies so much on his instinct that it is difficult to work as hard as an ordinary person in the other two respects.

And this is precisely the common problem of many geniuses - self-righteousness.

They take it for granted that their efficiency can make them invincible, but they forget that the passage of time is the fairest thing in the world, and anyone who can't catch up with it will eventually be ruthlessly abandoned by it, and geniuses are no exception.

"I asked Professor Dumbledore about you before the entrapment of Bellatrix began, and he told me. As soon as you graduated, you were recruited into the Auror office of the Ministry of Magic because of your talent, but you continued to train until this year to qualify, because you barely passed the 'stealth and stalk' class. ”

"That's when I regretted that I didn't stick to the action." Catherine gritted her teeth and said, "The results also proved my concerns, it was indeed because of you that the operation failed, but I didn't expect that the principal would let me serve as your special training teacher." ”

"I don't really understand." Tonks was startled by the red-haired girl's sudden gaze. "When I saw you, I thought it was just for you to teach me how to control my nervousness, and then I assumed that you used a polyjuice potion," she glanced at Catherine carefully, and quickly finished her words, "but the headmaster told me you didn't." ”

"Our Headmaster Dumbledore is truly adorable!" Catherine said with a smile. At the same time, she took out a pen and paper and hurriedly wrote two notes, and then Tonks saw a green light, and then she found that the two notes were missing.

"What's that green light?" Tonks asked, shocked, but Catherine didn't answer her mind.

"My target is the mystery man. So," Catherine asked with a raised eyebrow and a smile, "are you sure you want to know the secret of my victory?" ”

Tonks shook her head hurriedly, for the first time she truly realized how different Slytherin was from other houses.

"Ever heard of 'stand-ins'?" Catherine asked suddenly.

Tonks nodded honestly.

"Can you tell me what a 'stand-in' is?" Catherine asked again.

Tonks opened his mouth. Finally, he shook his head honestly.

"'Avatar' is the most difficult camouflage technique because it is not like 'disguise', it only needs to be disguised for a certain period of time. Its appearance and disappearance are completely out of the control of the pretender, so it must be prepared at all times, and it cannot even hold itself. Catherine's gaze suddenly darkened as she said this, but quickly regained its sharpness.

"As for what I used just now, it's just 'illusion', it's difficult to attack, and it's easy to be recognized, if I don't know your details, I won't use it on you easily, because the premise of its use is to know yourself and your opponent, of course, this is also the premise of all camouflage techniques."

"Can I learn?" Tonks asked, blinking.

Catherine looked her up and down, and categorically vetoed: "No, your observation skills are not meticulous enough, and your mastery of basic magic has not reached the level of mastery at all, and you can't even control your own magic power freely."

Tonks was dumbfounded, and after a long time, he exclaimed, "Can anyone else do such harsh conditions?" Seeing Catherine's disdainful gaze, she hurriedly added, "Except for you." ”

"Humph! If it weren't for the fact that your talent is so rare, and the headmaster would never allow me to join the 'frontline battlefield' before I graduated, I wouldn't have ignored you, because to be an intelligence officer, you must first be cautious, but you ......"

Before Catherine could finish her sentence, Tonks' elbow hit the lamppost beside her, grinning in pain, but she didn't dare reach out to rub it, because the red-haired girl's gaze had become colder and colder.

"Looks like I'm going to have to make 'cautious' a habit for you to remember first." Catherine suddenly showed a bright smile, and Tonks immediately felt a chill rush from the soles of her feet to the top of her head.

"I made an appointment to meet at the port of Weston-on-the-Sea at midnight on the 21st, so we have three days to play a game of 'Aurors hunt fugitives', except that your identity is not 'Aurors', but 'fugitives'."

"Huh?" Tonks couldn't help but let out an exclamation, but Catherine said to herself.

"Don't worry, even if you are caught by me, I won't send you to Azkaban, but," Catherine's smile grew brighter, "I've traveled abroad this time, but I've prepared a lot of potions to deal with some bad guys. ”

"So, in order to successfully capture you, the 'fugitive', I will not hesitate to use them on you, as for my potion production level, Professor Snape has given an evaluation of 'E' or above in the past three years."

Tonks' forehead was instantly covered with cold sweat, for a Hogwarts graduate who had been taught by Snape for seven years, she knew very well how harsh her Potions professor really was, so she didn't dare to underestimate Catherine's potions making skills, let alone verify whether the red-haired girl's words contained water.

"You can use any method to evade my 'pursuit', including apparition, however, the purpose of this game is to make you develop a habit of caution, so it's best to use the apparition in front of me, and remember to go back to my surroundings after escaping, after all, I don't know how to move magic long distances." Catherine suggested very sincerely.

Tonks nodded seriously, then his eyes widened abruptly, and he asked in surprise: "You only mentioned apparitions, does that mean that you can use magic outside of school?"

Catherine raised her eyebrows and said with some appreciation: "It seems that your Auror training has not been in vain!"

"You're still underage, you should still have traces on you, how can you not be noticed by the Ministry of Magic?" Tonks asked, shocked.

"It's your problem." Catherine smiled and announced, "Now that the game begins, you have three minutes to prepare, and after three minutes, I'll immediately start the 'hunt'." ”

Tonks was stunned, then gritted her teeth and turned around, she didn't want to lose to a third-year student more than to solve her doubts, even if this student was Catherine, who was stronger than herself, even if they were just playing games.

It turns out that Tonks is indeed perfect when it comes to "hiding and disguise", at least no longer a beginner who only uses her talents, so it can be seen that her training at the Ministry of Magic is not a waste of time, but her mentality is not ordinarily bad.

Catherine only got closer, and Tonks began to panic, and when the girl's gaze swept over, her behavior immediately became chaotic, and immediately attracted a large number of eyes around her, and then she could only cast a confusion charm on herself, and then immediately use the apparition to appear, and after a while, she appeared near Catherine again in disguise as another person.

After tossing like this six or seven times, Tonks was finally able to control himself a little, and no longer made a big move every time, but the nervous mood was still very easy to arouse Catherine's suspicion, she didn't dare to bet on the chance that she would not be discovered, so she had to flee immediately, taking advantage of the moment when the street turned and her vision was blocked, quickly changed her appearance and clothing, and blended into the crowd again.

After turning five streets, Catherine found that she could not find the person who behaved abnormally in the first place, apparently Tonks had begun to be able to control her emotions, seeing that the girl had to look up at the store next to her, and after discovering that it was equipped with a surveillance probe outside the store, she immediately went in to find the store to borrow the surveillance video.

Although Tonks used a confusion charm when changing her disguise, making it impossible to record the surveillance footage, Catherine's goal was simply to identify the most suspicious candidates through her walking route.

Although Tonks had learned about the Muggle world's surveillance equipment during his training, and had personally demonstrated the extent to which magic interfered with these things, he did not know that Catherine was far more familiar with them than she was, so she was immediately blindsided when she noticed that the girl was suddenly staring at her.

Tonks really didn't understand how Catherine had found her, and she panicked again, which made her unable to escape the girl's stalk for the next few hours, and finally she gritted her teeth and used the apparition to escape to other places to adjust her mood. (To be continued......)
