My older sister is a voice actor and my younger sister is a pornographic cartoonist!

Su Luo felt that this female clerk might be his breakthrough point, so he decided to go up to her and ask, "Excuse me, what happened in the store?"

"Huh?" The female clerk was stunned for a moment. She quickly glanced at the red-haired lady, and after seeing her nod, she said, "Actually, it's like this. A book in the store is missing."

"There's a thief? Don't you have surveillance?"

"Surveillance is useless because the books lost were borrowed."

"Books borrowed? What do you mean?"

"Take a look at this library card. Our bookstore not only sells books but also lends them out. Borrowers need to register their identity information on the card."

The female clerk took out a library card and showed it to Su Luo. On the name list of the library card, there were many names written in black water-based pen, all of which had been crossed out by others with red water-based pen.

Once the borrower's information is blacked out, no one will know who borrowed the book. The person who borrowed the book will definitely not return the book. The store's losses will then be borne by the female clerk because this happened while she was on duty.

"I just went to the restroom and came back like this." The female clerk's eyes were full of helplessness.

"Didn't the surveillance footage capture who scribbled on the library card?"

"If there was one, I wouldn't be so distressed. To be honest, the security camera at the cash register is broken."

"Oh?" Su Luo heard the key information, and he immediately looked at the red-haired lady, as if he had guessed her identity.

The red-haired lady also returned a knowing smile. She also realized that she might have been exposed, but she still wanted to wait and see what Su Luo would do next.

"Isn't it just catching a thief? What's so difficult about that? We can go ask the people in the store. Maybe someone just happened to see the thief committing the crime?" At this time, Xiaoli suddenly jumped out smartly. She thought that with so many people in the store, it wouldn't be strange even if someone noticed the actions at the cash register, right?

If we just ask them one by one then the problem will be solved, right?

"My silly sister, can you remember how many people entered the store behind us and what they looked like?" Su Luo asked his silly sister speechlessly.

"Uh...well." The silly sister tried hard to recall, she didn't seem to see anyone enter the store.

“So, no one cares what a complete stranger does.”

"Hmph! I'm helping you, and you call me stupid!" Xiaoli pouted angrily.

"Okay, okay, my Xiaoli is very smart, but your brother doesn't need help anymore because all the puzzles have been solved." Su Luo smiled slightly.

"You really know?" The girls' eyes lit up, and they were also a little surprised.

How did he know this? He just asked a few questions and he knew that?

Are you pretending to be cool?

"Of course I know. No matter who the red-haired sister is or the clown who tampered with the library card, let's see how your brother will get to the bottom of the truth." Su Luo smiled confidently.

"Oh wow?" Even the red-haired lady narrowed her eyes in disbelief.

If Su Luo guessed her identity, she could believe it, after all, the female clerk had just revealed the key clue.

But she simply didn't believe that Su Luo knew who had tampered with the library card so quickly.

Because she had been having a headache for quite some time before Su Luo came.

So she wanted to see how this brother, whom Su Mohan missed all day long, would get to the bottom of the truth!

Chapter 11 Solve the puzzle!

"Tell me quickly, who is the thief!"

When the female clerk with a C+ cup size learned that Su Luo had found the criminal, she excitedly grabbed Su Luo's hands.

As a result, this actually delayed the time it took for the female clerk to learn the truth.

You have to know that Su Luo's sister was still next to them. She didn't even allow her old friend to touch her brother, let alone this girl who she had never seen before but had big breasts.

So the elder sister quickly stepped forward, forcibly pulled the female clerk away with a bad look in her eyes, carefully protected her brother behind her and said, "Sister, please don't touch my brother, he is allergic to women, thank you."

"what?"

As soon as my sister said this, not only the female clerk was stunned, but Su Luo was also stunned.

When the hell did I become allergic to women again? How come I didn’t know?

Sister, no matter how much you don't want your brother to find a girlfriend, you don't have to go to such great lengths to ruin his reputation, right?

Su Luo really wanted to complain that he was not allergic to women, but his sister suddenly gave him a "kind" smile, as if to say, if you dare to talk nonsense, your sister will practice Aikido tonight!

Su Luo instantly recalled the fear of being used as a sandbag by her sister for training, so she shamelessly obeyed her heart.

The red-haired queen was also speechless about her old friend's behavior. Was her protection of her brother a little too exaggerated?

Even if you really want to protect me like this, you have to find a reliable excuse. What the hell is allergic to women?

"But aren't you holding his hand?" the female clerk asked with some confusion.

It was the first time she heard of someone being allergic to women. What would Su Luo do about getting married in the future?

Do you want to marry a man?

And since Su Luo is allergic to women, why is there no problem for him to hold hands with his sister?

Difficult, could it be said...

Is his sister the legendary cross-dresser?

"That's because we are family and have lived together since childhood, so he already has antibodies," my sister explained.

"Really..." The female clerk was silent for a moment. Although she still doubted what the sister said, she did not intend to continue asking.

After all, she didn't have to hold Su Luo's hand. She was only curious about the truth of the incident.

"Then can you tell me the truth of the matter? Who is the thief?" The female clerk stopped asking about Su Luo's affairs and continued to ask about the business.

Everyone was curious about how Su Luo knew the identity of the criminal after just one look at the debit card. Could it be that the criminal was still in the bookstore?

"Regarding this matter, I still need a small prop to make the criminal's name appear on its own." Seeing that the main topic had begun, Su Luo quickly jumped out to continue explaining.

"What props? I'll find them for you." The female clerk asked quickly.

Can he make the prisoner's name appear on its own?

"Help me find a piece of red, translucent plastic film, like the kind students use to pad their exam papers."

"Oh! I know what it is. We have it in our store. Wait a moment, I'll go find it."

The female clerk ran away a little excitedly. After all, if the thief was found, she would not have to compensate for the store's losses.

In addition, she actually saw a detective mystery drama in real life, which inevitably made her feel excited.

Although she didn't know what Su Luo was doing with the red translucent object.

Soon, while everyone was waiting, the female clerk ran back with the items Su Luo needed in her hands.

"Here it is, what are you going to do with it?" the female clerk asked curiously.

"It's simple. Try placing this red, translucent plastic pad on top of your debit card and then look at the name on it."

"Is that right?"

The female clerk followed Su Luo's instructions and tried to move the plastic pad to the top of the debit card, looking forward to what would happen next.

As soon as it was put on, the female clerk's eyes lit up immediately, and she couldn't help but burst out in surprise: "It really worked, it's amazing!"

"What? What came out? I want to see it too!"

Xiaoli was very curious about the female clerk's reaction and quickly ran forward to watch.

My sister and the red-haired lady also came over. Through the red translucent plastic, they actually saw the names on the debit card that were crossed out with a red pen.

But when they removed the translucent plastic, the debit card was once again covered in red pen.

Image: "Optical Principles!", Location: "Images/1536742805-100079513-102411288.jpg"

"There is such a method? What's the principle behind it?" This time even the red-haired lady was convinced. She really hadn't thought of this method.

She didn't expect that this little brother could solve the problem that had troubled her for a long time with such a simple method.

"Didn't you listen carefully in physics class? This is an optical principle. It roughly means that red translucent plastic absorbs red light, making light of other colors visible." Su Luo explained lightly.

After the red light is absorbed, the black text hidden underneath naturally appears.

Of course, this is also thanks to the fact that the criminal was too anxious when committing the crime, so he did not use the red pen too densely, otherwise this method might not work perfectly.

But if we really want to say that the criminal was stupid, since he had time to smear the debit card, why didn't he just take the debit card away and dispose of it?

Maybe this is the legendary awful villain?

But if you think about it carefully, there are even idiots who carry kitchen knives to rob banks, so this level of idiots should not be uncommon.

"Tsk tsk, you do have some skills." This time the red-haired lady finally believed that Su Mohan's praise for her brother was not empty boasting.

In fact, just from the look in Su Luo's eyes when he was thinking seriously about something, she felt that this person might really have some ability.

"Hmph! He just happens to know some useless stuff." Xiaoli snorted in dissatisfaction.

Although she felt very proud that her brother successfully solved the puzzle, if he was so smart, why did he need to be reminded even to compliment a girl on her pretty clothes?

Xiaoli became more and more suspicious that her brother was deliberately not wanting to praise her.

"No one in this world knows everything from the beginning. All successful people have accumulated those seemingly useless little bits of knowledge." The red-haired lady refuted Xiaoli's statement.

She didn't really think that Su Luo was just lucky. The accumulation of knowledge is essential for solving cases.

How can someone who knows nothing solve a case?

"But there is another problem. There are ten names of these prisoners painted in red. Which one is the prisoner's own name?" The female clerk was still a little distressed.

If you want to catch the criminal, you should at least know his name, right?

"What's so difficult about this? Just let the police question them one by one. Those with poor psychological quality will be exposed immediately. Or we can wait slowly. After the other nine have returned the books, the one who hasn't returned it will be the criminal, right?" Su Luo said lightly, not taking her troubles seriously at all.

"So that's how it is!" The female clerk's eyes lit up again. She couldn't help but think that this person was really smart. This method was indeed simple and crude.

Although anyone could come up with this method, there are not many people who can think of it instantly like Su Luo.

"So, this beautiful red-haired policewoman, what method do you plan to use to catch the criminal?" After solving the puzzle, Su Luo smiled at the red-haired policewoman and revealed her true identity.

Chapter 12 Policewoman Sister!

"Policewoman sister?"

When Xiaoli heard these words, her expression was stunned.

This red-haired girl who looks so aggressive is actually a police officer?

Then she has to be careful when talking to the other person. Will she be thrown into the detention center if she uses bad words?

Xiaoli looked at the beauty carefully, and to be honest, she couldn't see that she had the temperament of a police officer at all.

After all, that long red hair is so eye-catching. Is it possible for a policeman to dye his hair?

"How did you find out that I was a police officer?" The policewoman no longer concealed her identity, but just wanted to hear Su Luo's reasoning.

"I didn't think of it at first, but when the female clerk told me that the surveillance equipment at the cash register was broken, I guessed it."

"Is it really because of that place?" The policewoman also thought it was because that place was exposed.

"Yes, the cash register is such an important place. If she's not stupid, how could she possibly tell me, an outsider, that the surveillance there is broken? If money is lost, will she be responsible?" Su Luo expressed his thoughts, and then said, "So I thought, she must trust me, that's why she told me such important information. As for why she trusts me, it's because she trusts you. You agreed with her, so she naturally dared to say it."

Su Luo still remembered that when he asked the female clerk what happened in the bookstore, the female clerk first looked at the policewoman for her opinion, and then told him the situation.

After all, the police agreed, so what else was there for her to be afraid of saying?

"It's true that I agreed, but what if I'm the store manager? As the store manager, if I agreed, it wouldn't be surprising that she dared to tell you that the surveillance was broken, right?" The policewoman posed a difficult question to him.

"Impossible, you can't be the store manager." Su Luo firmly denied this statement.

"What makes you so sure?"

According to Su Luo's analysis, it is entirely feasible to regard her identity as the store manager.

Why on earth did Su Luo think that the girl with dyed hair was not a store manager but a police officer?

"Perhaps you don't know, but before my sister and I came to see you, she said something to me."

"What? Has she already hinted at my identity?"

"That's not the case. My sister just told me that she found something interesting."

"What's wrong with that?"

"That statement is enough to prove you're not the store manager. If you were, your presence here wouldn't be surprising. If that's the case, when Sister saw you, she shouldn't have said, 'I discovered something interesting,' but rather, 'I stopped by to say hello to an old friend.' But since Sister said it was something interesting, she must have thought it wasn't surprising for interesting things to happen around you. And now that a crime has occurred in the bookstore, it's easy to conclude you're a police officer."
