Siheyuan: Starting from the promotion of an engineer

Chapter 181 Don't take chances, you need to be in awe of scientific methods

Hear what Lin Zhen said.

The third uncle Yan Bugui immediately had hope, and said happily: "Lin Zhen, you, what can you do? Tell me quickly!"

"Sir, don't worry, I have already asked Xu Damao to go to the clinic to buy iodine. I learned from the security department that if you heat and fumigate with iodine, you can reveal your handprints and fingerprints. When the time comes, whoever smashed it with a brick will be compared. You can see it."

As soon as Lin Zhen's words came out of his mouth, Yi Zhonghai's heart skipped a beat.

He believed that Lin Zhen had this ability, although he didn't know why.

"Bang, did you smash the solar cooker at Grandpa San's house?"

"No! Woohoo, I didn't!"

The corners of Jia Zhang's mouth twitched violently, and he curled his lips and said, "Master, don't ask me like that. It has nothing to do with you. This meeting is over. You are in charge. Why do you care about others? The meeting is over!"

She shouted quite vigorously, but no one at the scene listened to her.

Lin Zhen asked: "Bang, did you smash it? I'll give you a chance to admit it voluntarily. It won't work if you cry after I find out!"

Sticky looked at Lin Zhen resentfully, "It's not me! Woooooo..."

Qin Huairu complained: "Oh, Lin Zhen, why are you scaring a child? After dinner just now, he said he ran out to the latrine, and he was beaten by your boss and second child after a short time. You can't always be skeptical about sticks, can you?"

Qin Huairu didn't have to play tricks, she just didn't believe that Lin Zhen could show Brick's fingerprints.

Since I don't admit it, I don't admit it from the beginning to the end. Anyway, I can't be cheated by Lin Zhen.

Jia Zhang curled her lips and wanted to say something ugly, but she didn't have the guts. She had already been beaten by Lin Zhen a few times, and she had a long memory.

He was so angry that he sat down on the stool, holding his breath and glaring at the neighbors.

Silly Zhu waved his hand and said: "Okay, okay Lin Zhen, so how about being serious? It's not that it can't be repaired, but it must be the same as catching enemy agents?"

Yan Bugui said: "Hey! Silly Zhu, you are not serious, so will you pay the money? You will pay for it?"

"Am I worth it? Do I have a penny with me?"

Lin Zhen said coldly: "Silly, don't get along with me. Of course, this matter has to be investigated. If it wasn't for the stick, wouldn't my Lin Guo and the Lin family have been beaten for nothing? The two of them should apologize." Gotta apologize!"

Qin Huairu sighed and said: "Forget it, it's not the first time that the stick was beaten by Lin Guolin's family. It's a child's play, what apology!"

"No, you can't let the bad guys go, and you can't wrong the good guys. If it wasn't done by the stick, Lin Guo and the Lin family not only have to apologize, but also have to stand still and let the stick fight back!"

Lin Guolin's family immediately stepped forward, waiting for the result.

"Look, it's still Lin Zhen, pay attention!"

"Yeah, don't protect yourself!"

"I think Lin Zhen can really show his handprints."

The neighbors started talking again.

Jia Zhang's mouth curled up like a dipper, she couldn't believe that Lin Zhen could show that handprint.

What about dreaming?
Touching a brick can leave a fingerprint?
You are more powerful than Bao Gong and Di Gong, and you can solve cases better than Peng Gong Shi Gong!
Like when I haven't seen the movie!
snort!
Qin Huairu's face was calm, and he nodded slightly at Yi Zhonghai.

She also didn't believe that Lin Zhen could do it, thinking it was a fraudulent trial.

Quietly waiting for Lin Zhen to stop acting.

To be on the safe side, she quietly asked He Yushui again.

"Can rain and iodine smoke out fingerprints? What's the reason?"

He Yushui went to high school, but the knowledge he learned in high school is not as much as ideological education.

She was an activist when she was in school, and she was not interested in anything that had anything to do with scientific knowledge, and she hardly learned anything.

"Sister Qin, it's been two years since I graduated, so I've forgotten about it long ago, but I'm sure, I've never heard of it!"

When Qin Huairu heard it, the only stone hanging in his heart fell to the ground.

It's funny in my heart, Lin Zhen, don't try to lie to me, high school students haven't heard of it, so it's nothing, it's up to you to see how it ends in a while.

"Iodine is here!"

Xu Damao shouted as soon as he entered the courtyard.

Lin Zhen took the iodine wine, it was half a catty, a bottle full, and he didn't open his mouth yet.

Standing up, he said to the neighbors at the scene: "I hope whoever smashed it will admit it now, and when I pour it into the pot for fumigation, I will regret admitting it later, and the nature will be different!"

"Cut! Virtue!" Jia Zhang said coldly with his mouth curled.

Qin Huairu couldn't help laughing too, Lin Zhen's repeated questions were all deceitful?
If he could really show his fingerprints, with his swift and resolute personality, he would have already set fire to fumigation.

"Okay, Lin Zhen, I've never heard of something, can you succeed? The first uncle and the second uncle are willing to pay for reflective glass. The conflicts in the courtyard should be minimized and should not be exacerbated. Stop making trouble soon. !"

"No, Qin Huairu, you are wrong, the ending is unclear, and conniving and covering up those who made mistakes is called increasing conflicts. I haven't heard that it's because of you, but it doesn't mean that you can't succeed!"

Lou Xiaoe, Yu Li and Liu Yuhua have already turned on the coal stove and put the pot on.

Lin Zhendao: "My kitchen is small, and we can't let everyone in. Let the three uncles and a few representatives come in and have a look. I'll explain the principle to everyone!"

As he spoke, he gently pinched a corner of the brick and raised it up for everyone to see.

"Our hands are sweating and grease all the time, but the eyes can't see it, but it will stay on the things we touch. In summer, we sweat more. When the iodine is smoked, the wine will run out. , the iodine is left behind, and as soon as the iodine is next to the sweat and oil of the hands, alas~ it changes color, and the fingerprint comes out!"

Yan Bugui laughed loudly when he heard the clapping, "Hey! Why didn't I think of it, only the senior chemistry teacher knew about it!"

The third aunt said happily: "So the solar cooker can find someone to pay for it?"

"That goes without saying, let's go, follow along!"

Jia Zhang smiled coldly, "Who are you bluffing?"

Qin Huairu's heart skipped a beat, and she hastily pulled the corner of He Yushui's clothes.

He Yushui shook her head lightly. She really didn't like mathematics, physics and chemistry when she was in school.

Silly Zhu said with a smile: "What about playing? It's interesting!"

Seeing that Jia Zhangshi and Qin Huairu still did not respond, Lin Zhen went straight into the kitchen.

After a while, the iodine gas was purple along the side of the pot.

Lin Zhen held the corner of the brick and turned it back and forth in the purple steam, and the whole thing was full of smoke.

In a blink of an eye, a brown handprint appeared on the brick.

Lin Zhen held it up to the light and turned it around for everyone to see.

The third uncle was so happy that he couldn't close his mouth from ear to ear, "Qin Huairu! Pay me, pay me!"

The third aunt was also very happy, "Qin Huairu, you can't deny this, right?"

The first uncle, Yi Zhonghai, was silent, and the second uncle, Liu Haizhong, curled his lips and said, "It's true that you should pay for it, and you have to apologize!"

Sha Zhu tilted his head and frowned, and couldn't help saying: "Hey! It's such a mess!"

Regret can no longer describe Qin Huairu's mood at this time.

There is also the helplessness of being caught by chance and the shame of ignorance and arrogance.

On the half of the brick, there are impressive handprints, the kind where the index finger and middle finger of the right hand are broken off.

Others can't imitate it even if they want to, it's simply the exclusive mark of stick stems.
