Yu Fan: "We have been subjected to Zhang Caixia's way!" Hit the plan. ”

Wang Ka and the second brother didn't understand what was going on, so they pricked up their ears and listened to Yu Fan.

Yu Fan: "When Zhang Caixia wrote the IOU today, she didn't take the pen in the pen holder on the table, but turned over a pen in the drawer, and this abnormal behavior may be the reason for this blank IOU. ”

Wang Ka and the second brother were still very confused, and Yu Fan continued to explain: "The pen she took from the drawer was not an ordinary pen, but an unscrupulous magic pen!" ”

Yes?! What is it? The second brother and Wang Ka looked at each other.

Yu Fan said: "This kind of pen is also called a fade pen, the ink of this pen is a special chemical reagent, the chromophore in this ink will be destroyed by the oxidation of oxygen in the air, so the handwriting will disappear after a period of time, and the speed of disappearance will also vary depending on factors such as ambient temperature and writing speed. ”

Wang Ka asked: "Does it mean that the words written in this ink can be seen at the time, and after a period of time, the words will disappear by themselves?" ”

The second brother exclaimed: "Huh! What kind of magical thing can Zhang Caixia get? ”

Yu Fan shook his head: "This thing is actually not difficult to do at all, Taobao searches a lot." I also know its formula, the ink includes a colorant and an alkaline buffer composition, and also comprises the following raw material components by weight: 1~10 parts of glycerin, 0.2~0.8 parts of photosensitizer, 0.1~0.5 parts of preservatives, 0.5~5 parts of antibacterial agents, 0.5~1 parts of flavors, 0.2~1 parts of surfactants, the alkaline buffer composition comprises the following weight parts of raw material components: 30~80 parts of distilled water, 20~80 parts of ethanol, 1~5 parts of sodium hydroxide, 1.5~10 parts of sodium alginate, 1~6 parts of sodium carbonate, 2~8 parts of sodium acetate, 1~10 parts of sodium borate and 0.2~1 parts of stearic acid. ”

Wang Ka and the second brother expressed their amazement, can you memorize this?

Yu Fan then analyzed: "It seems that this Zhang Caixia is determined to play to the end, but the situation is not in our favor, what we are holding is just a blank piece of paper, and there is no evidence at all." We've ignored it. ”

The second brother took a glass of wine at this time, smacked his lips, and said, "This little fox is going to mess around, then don't blame us for being polite, let's go together again tomorrow, and my brother will deal with this matter for you." ”

Back at home, Yu Fan didn't sleep well all night, and he couldn't think of a good way to do it, and the second brother kept saying that he would think of a way, but when he asked him what the way was, he couldn't say one, two, three.

It's just tangled, it's dawn, it's really a difficult night.

The three of them gathered early in the morning and rushed to Chengdu Dumb Fire Technology and Zhang Caixia's company together.

Guo Na is right, XA has indeed cooled down a lot, and there are small snowflakes in the sky today, which seems to be the first snow of the year. Yu Fan secretly felt that today might be a little unusual.

The three of them stepped into the door of Chenghuo Technology with great momentum, and the second brother roared: "Where is Zhang Caixia?" Come out for me! ”

An employee pointed to the general manager's office and said, "She's in the office." In addition......" the employee lowered her voice and whispered, "she didn't pay everyone yesterday, and after you left, she took the money to buy bags." ”

Wang Ka secretly scolded in his heart: "There are such brazen people in the world! ”

The three of them didn't say a word, and went straight to the general manager's office, and the second brother walked in front and directly unscrewed the door.

Zhang Caixia stood by the window, holding the phone in her hand, as if she had just finished talking on the phone.

The second brother roared: "Zhang Caixia, you have gone too far, today you have to return the 19,000 yuan you owe to Mr. Yu!" ”

Zhang Caixia made an innocent expression: "What are you talking about?" I paid off all 20,000 yuan yesterday, when do I owe you money? Don't spew blood. ”

The second brother said sarcastically: "Little girl, you can really act, yesterday you deliberately wrote us an IOU with a magic pen, and this IOU will be gone after you go back, this is your trick, right?" ”

Zhang Caixia continued to pretend not to know: "I don't understand what you're talking about, obviously you took 20,000 yuan, and then returned the previous IOU to me, when did I write you an IOU again, did you make a mistake?" ”

Yu Fan has been observing Zhang Caixia from the side, this kind of character trait Yu Fan has rarely encountered before, such a move, every word and deed completely sets the bottom line of morality. In fact, there must be an unspoken logic behind all the laws of psychology, and ordinary people are under normal logic, in this case, people's behavior follows a law. However, some will lead to psychopathology for some reason, at this time, all the previous logical foundations are almost completely broken, for this kind of abnormal situation, psychology has a special branch of research - abnormal psychology.

Zhang Caixia's personality traits belong to a very extreme example, she has low self-esteem but extreme self-confidence, she is extremely strong in her heart, but she is very good at using her pitiful coat to win sympathy. Under this contradictory setting, the moral balance that was supposed to measure people's mentality naturally fails. Zhang Caixia's view of gain and loss is set aside in a new self-established moral system.

That's why her acting will be so realistic, and she will become more and more skilled in deceiving, because there is no moral constraint, and naturally there will be no feelings of shame.

The second brother was very angry and threatened: "Zhang Caixia, don't toast and don't eat and drink, you have no way back, you have to return the money today, otherwise I will be unkind to you." ”

"No way back?" Zhang Caixia's attitude suddenly became arrogant, "Hahahaha." Zhang Caixia laughed demonically, she had completely torn off her disguised mask.

Zhang Caixia said lightly: "Mr. Yu, when we met for the second time, you conducted a psychological analysis of me, saying that Lao Lai generally has five routines and does not repay the money, I am deeply impressed." First, play the emotional card and pretend to be pitiful; second, swore an oath and promised to repay the money at a later date; third, deliberately running away and pretending to disappear; Fourth, find fault with the borrower and put the borrower in an unkind and unjust place, and then the borrower will retreat in the face of difficulties; Fifth, violence is not returned. ”

Yu Fan looked at Zhang Caixia coldly, with an ominous premonition.

Zhang Caixia continued: "You also concluded that I could only use the last card in my hand last time, and I didn't pay back by finding faults. He also said that I had no more cards to play. Then today you are going to open your eyes. Zhang Caixia clapped her hands as she spoke.

Suddenly, nine strong men rushed in from outside the door, each with a face full of flesh, fierce and vicious, and menacing. Nine people rushed in and quickly surrounded Yu Fan and the three.

Zhang Caixia walked to the door of the office, slammed the door shut, and pressed the lock.

With a hideous face, he said, "Then let me show you my fifth hand!" ”
