In the hall, everyone gathered and couldn't help but marvel at the incredible scene in front of them.

"How so?"

Xiao Hu's fingertips...... It's turned red?"

"Everyone has soaked it just now, but why is it that only Xiao Hu's fingertips have turned red?"

"What hell is this magic?"

At this moment, Xiao Hu was also taken aback by his own operation, he quickly withdrew his hands and carefully checked his hands for signs of injury.

After Xiao Ya on the side saw this situation, the whole person was also shocked, and she hurriedly asked Gu Chen beside her: "Classmate Gu Chen, is this ...... Why the hell is going on? Why did Xiao Hu's fingertips turn red?"

"Yes, everyone has tested it just now, and I haven't seen this happen?" Yuan Han couldn't say why, so he could only throw the question to Gu Chen.

"Because he's a thief. Gu Chen calmly walked over, came to Xiao Hu, and said, "Xiao Hu, what else do you have to say?"

"I ...... What do you mean?" Xiao Hu didn't even dare to look directly into Gu Chen's eyes now, his eyes tried his best to avoid them.

"It's not interesting. Gu Chen also sneered: "I just said that lemon juice is a magical drink, it can help me find the real perpetrator, and this person is you." ”

"Hu ...... Nonsense. Xiao Hu sneered and said, "It must be you who are making trouble, it must be." ”

In fact, when Xiao Hu saw this scene, the whole person was also confused.

After living for so many years, it is the first time I have encountered this situation.

If it was a magic trick, he might still reluctantly believe it, but just now Ruan Wenhao and the others put their hands in the vessel, and their fingertips did not turn red, but why did their fingertips quickly turn red when they put their hands in?

"Officer Gu. At this time, Yuan's father also came over and asked, "What method did you use, how can you be sure that the person who stole the ring and destroyed the scene was Xiao Hu?

"yes, it feels like magic. Mother Yuan was also confused: "This good lemon juice, why did it make Xiao Hu's fingertips turn red?"

Not to mention these people, even everyone in the audience is now at a loss.

Gu Chen walked to another long table, took a purple cabbage in his hand, and said, "If you want to provide me with convenience in handling cases, it should be this purple cabbage." ”

"Purple cabbage?" everyone said in unison, feeling that Gu Chen's speech was a bit cloudy.

"Purple cabbage, also known as purple cabbage, is a nutritious vegetable rich in vitamins, carotene and crude protein. Gu Chen checked the purple cabbage in his hand and said, "Moreover, the vitamins in the purple cabbage can provide oxidants for the human body and enhance people's vitality." ”

"That's right, my family grows pollution-free green food. Yuan Han couldn't help but praise his own vegetables, but looking back, he said again: "But classmate Gu Chen, what does this have to do with Xiao Hu's fingers turning red?"

"Quite simply, because purple cabbage juice has the property of changing color when encountering acids or alkalis. Gu Chen raised the purple cabbage in his hand high and continued: "It itself can be used as a chemical indicator, it will turn red when it encounters acid, and it will turn green when it encounters alkali. ”

"I know, I know now. ”

Just when Gu Chen was halfway through his words, Wang Lifeng jumped out and interjected: "Lemon juice is an acidic drink, so when purple cabbage juice encounters acidic substances, it will naturally turn red. ”

And just now to take out the diamond ring placed in the purple cabbage, you can only peel off the leaves layer by layer, and it is precisely for this reason that Xiao Hu's hands must be stained with a small amount of purple cabbage juice, which is why only Xiao Hu's fingertips have turned red. ”

"So that's it?"

After hearing Wang Lifeng's explanation, many people suddenly realized for a while.

That's right, after the wire tripped in the hall on the first floor just now, when everyone found the purple cabbage in the tray, it was indeed peeled off layer by layer.

And those who operate it themselves will definitely have a small amount of purple cabbage juice on their hands.

Now everyone understands why Gu Chen is playing tricks just now, it turns out that this little policeman has long known these principles, so he will come up with this kind of strategy, so as to use the characteristics of purple cabbage and lemon juice to find the thief.

Several middle-aged people who were laughing at Gu Chen just now suddenly looked at Gu Chen's eyes.

Do you feel that the current police handle cases like this?

"Brother Xiao Hu, is it really you?" Xiao Yadai looked at Xiao Hu with a slight frown, feeling that this result was unacceptable.

Xiao Hu became the target of everyone, he lowered his head, did not dare to look at Xiao Ya's pretty face, and was speechless for a while.

And Ruan Wenhao, who was beaten just now, was happy, and sneered: "It turns out that you are the real thief, it seems that you really know people and don't know your heart, you are Xiao Ya's best hair, you actually did such a thing." ”

Ruan Wenhao didn't even have the idea of making a move now, feeling that even if he didn't do it, others would not let him go.

Doing such a immoral thing at someone's engagement scene, it seems that this Xiao Hu can't eat and walk around.

"Xiao Hu, let me ask you, have I wronged you?" Gu Chen still walked in front of Xiao Hu and confirmed with him.

Xiao Hu shook his head: "No, you are right, that's right, pull the electric switch, and the person who stole the ring is me." ”

"......"

"Is it him?"

"I didn't expect him to be this kind of person?"

"It was really like it just now, and it beat Ruan Wenhao to the point of being miserable, it seems that everyone misunderstood Ruan Wenhao. ”

There was an uproar at the scene......

Everyone looked at each other, feeling that such a result was really unexpected by everyone.

Thinking about the people who misunderstood Ruan Wenhao just now, they are also ashamed at the moment.

When Xiao Hu took the initiative to beat Ruan Wenhao just now, many people even said, "Kill him as a turtle grandson."

But now the situation has changed, and the thief is Xiao Hu, which is embarrassing.

"Brother Xiao Hu, why are you doing this? Are you short of money? But you shouldn't do such a thing on such an important occasion if you lack money?" Xiao Ya was about to cry.

I would never have thought that a young man who had been upset with himself since he was a child would do such a shameful thing at his engagement ceremony.

Well, now that everyone knows that the thief is their own hair small, the joke is probably bigger.

"Don't you know that I'm doing this?" Xiao Hu suddenly raised his head and looked at Xiao Ya with a straight look: "We have been childhood sweethearts since childhood, we go to school together, do homework together, I am always the first to rush forward when someone bullies you, you graduate and intern, I quit my original job and came to the same company as an intern with you, why am I difficult for you not to know?"

The scene suddenly fell silent, and everyone was stunned by this scene.

These words, put in the TV series, it is estimated that everyone understands people, but this kind of situation actually appeared in front of me, and I felt that there was a strong smell of vinegar in the entire venue.
