salina thought, ”your school should also have a chemical laboratory, some basic chemical experimental materials, right?”

”We don't have any in our school, but next door is the University of technology. There are all of them,” Dai said.

Salina laughed, took out paper and pen, and quickly wrote a pile of materials, ”please bring these materials, I can test them for you now.”.

After Dai Yun took the list, he immediately sent someone to the neighboring University of technology to quickly get back a pile of materials and containers for chemical experiments.

As soon as she got it, salina mixed some white liquid in front of everyone.

Salina's expression became quite solemn: ”the psychotropic drugs that we smelled just now, although we are not sure which one is, they usually cause chemical changes and turn blue when they touch my reagent.

I won't explain the specific chemical principles to you. In any case, even if we go to court, this is a very complete theory. ”

With that, salina poured some of the remaining water drops from the plastic cup into the reagent.

Sure enough, it didn't take long for the reagent to turn blue!

When people saw this scene, they all nodded, while Chen Xiaohan was more and more nervous.

”Miss Mu Mu Mu, you can breathe a few times on this reagent. This reagent is very sensitive. I think it will change color when you exhale and now,” said salina.

Mu Mu was busy doing it. After a few breaths, the reagent turned blue again.

Mu Xuesong clapped his hands, ”sure enough! I said my daughter's level, not like this! ”

Dai Yun and Ren Chuan and other responsible persons also nodded, which was a letter.

Then, salina went to the water dispenser, took some water, poured the reagent, but it did not change color.

”Well, this proves that the water in the water dispenser is OK.”.

After that, salina said to Chen Xiaohan, ”this classmate, you said that this medicine has nothing to do with you. Could you please put your finger in this medicine,

if you took the medicine, there might be residue on your hand If you don't change color, it will prove nothing, and you will be innocent... ”

Chen Xiaohan's face turned pale when she heard it. She walked stiffly in front of salina. She didn't dare to put her hand into the reagent.

”Classmate, it's OK. This potion won't hurt your hand,” said salina with a smile.

But Chen Xiaohan directly shook his head and cried: ”I didn't mean to! I'm really wrong!! Director Lu asked me to do it!! I was really wrong Wuwu... ”

When they heard this, they suddenly realized that it was really someone who instructed them secretly!

”Director Lu? You say Lu Wenxuan! ” Deputy principal Dai Yun asked.

”Well...” Chen Xiaohan bowed his head, ”he He said that when it was done, he would give me a full scholarship... ”
