章 105: Psychological Trauma

Shen Xi had said, "Be careful. Next time, I'll use sulphuric acid."

...

Big news broke out in Capital No. 4 High School. In the Mathematical Olympiad competition, everyone in the top class lost except Yu Qiubai.

On the day of the exam, no one knew what the top class ate wrong, but all of them had diarrhea, resulting in them being sent to the ER in the hospital and missing the exam.

A few people endured the pain and were determined to take the test while physically handicapped, but they lost after failing to stand it after a few minutes.

More than one participant from other schools revealed that a strange smell was detected ten minutes into the exam. One person could not hold it anymore and was carried off from the spot.

According to the hospital's diagnosis, the school determined that they had gone out to eat indiscriminately and had eaten something bad, resulting in collective food poisoning.
