Recently, a transaction involving “American cockroach powder” caused quite a stir on campus.It is reported that student Yang Defu privately purchased American cockroach powder, which is said to have miraculous anti-cancer effects, from Liu Xiaojing. However, after the transaction was completed, he was caught on the spot by his classmate Wang Yutian.
According to Yang Defu's explanation, she bought this powder because she heard that American cockroach powder has miraculous effects in fighting cancer.However, when Wang Yutian heard that it was cockroach powder, he had doubts about its selling price.In her opinion, this kind of powder should only be worth a few dollars per pound, but Liu Xiaojing sold it for hundreds.
Liu Xiaojing hurriedly explained that what she was selling were medicinal cockroaches, and the breeding environment and sanitary conditions were extraordinary.Yang Defu also said that she checked online beforehand and confirmed that American cockroach powder indeed has medicinal value.However, Wang Yutian was not satisfied with these explanations. She insisted on using scientific experiments to prove the true composition of the powder.
So Wang Yutian entered the laboratory with cockroach powder.Although she is confident that she can handle the chemical experiment, Yang Defu is still a little worried.However, Wang Yutian quickly used her professional knowledge to show her strength.When Liu Xiaojing tried to test her by describing the smell, Wang Yutian accurately identified the chemicals and reminded her to handle them with caution.But Liu Xiaojing did not listen to the advice and was admitted to the hospital due to inhalation of toxic gas.
This incident attracted the attention of the principal, who criticized Wang Yutian and asked her to wear protective clothing during the experiment to ensure safety.Under the supervision of the principal, Wang Yutian completed the experiment and announced the results: the so-called American cockroach powder was actually just starch.After learning the truth, Liu Xiaojing realized that she had hoarded a large amount of fake goods and quickly called the police.
Yang Defu expressed her gratitude to Wang Yutian for his help. She was glad that she had recovered the loss in time.At the same time, she also deeply understands the importance of healthy living, although she feels that going to bed early and getting up early is a huge challenge for her.
