This is an unexpected joy, Yu Wei obviously didn't expect it.

"Tut-tut, I really didn't see it, I found a treasure."

Everyone didn't understand what Zhou Changdong was talking to Yu Wei, and at this time, Huang Guihua frowned and couldn't help but interrupt the two of them.

"What are you talking about here? Where the hell is the watch? ”

Yu Wei was not in a hurry, and with a slow look just now, he picked up the stones that Chang Min had just brought back and said:

"These stones are rare phosphate rocks near our village, and I also found them by accident, not much, enough for this time."

"What's the use of this broken stone?" Huang Guihua didn't see any difference between this stone and ordinary stones.

Yu Wei didn't say the following words, but gave Zhou Changdong a look.

The look in his eyes seemed to say: Husband, give your mother a science popularization.

Zhou Changdong looked at her raised eyebrows, and he was infinitely amorous, thinking that maybe someone was born like this, even if it was unintentional, every smile was charming.

Zhou Changdong gathered his thoughts, glanced at Zhou Changli and said:

"This stone can extract a chemical called iodine, iodine has a wide range of effects, one of which can be used to identify fingerprints left in a certain place by the iodine vapor method, and the fingerprints of money for several months can be used."

Yu Wei listened to him, and said: "That's right, it's a fingerprint check, if you want to open the box, there are fingerprints of the person who stole the watch on the key and the box containing the watch, you only need to check the fingerprints, and the thief who stole the watch will know." ”

Zhou Changli is going to high school after the Chinese New Year this year, and there is knowledge of teaching chemistry in the school, and her academic performance is not good, and she doesn't know if what Yu Wei said to Zhou Changdong is right, after hearing what they say, she doesn't believe it.

"Bragging, everyone's hands are the same, can you see this?"

Yu Wei sneered, "You also went to school, don't you know that people's fingerprints are not similar to each other?" ”

Zhou Changli listened to Yu Wei's words, and her face turned even paler.

Yu Wei and Zhou Changdong looked at Zhou Changli's expression, and they both knew that Zhou Changli would not admit it, and she would only admit it if she was witnessed.

Mo said that this would be Zhou Changdong and Yu Wei, even Zhou Changfen and the Changmin sisters could also see that Zhou Changli was wrong.

Zhou Changdong looked at Zhou Changli and asked again in a deep voice:

"The last chance, who took the watch, now admit that the whole family will not blame her, and this matter has not been mentioned, otherwise, when it is really checked out, the family will not tolerate her. If your hands and feet are so unclean, there should be no such person in your home! ”

Zhou Changli knew that Zhou Changdong had always been a talker, he was really angry, even Huang Guihua had nothing to do with him.

Zhou Changdong was extremely scared in his heart, although he didn't believe that Yu Wei could really extract iodine from that stone, but what if?

Zhou Changli was frightened, and under the pressure of Zhou Changdong's gaze, Zhou Changli's mentality had collapsed.

She cried out, ran to Huang Guihua, hugged Huang Guihua's arm and said:

"I didn't think about stealing it, I just saw that it looked good, and I thought about taking it out and showing it to my classmates."

Yu Wei looked at Zhou Changli with a cold expression, and it was really different from the nine sons of the dragon.

is also Huang Guihua's daughter, there are those who are as bitter and mean as Zhou Changhua, as well as Zhou Changfen's kind and considerate of others, Zhou Changmin's lively and sunny, and Zhou Changli's selfish and insidious.
