"Someone poisoned it?" Chen Yuerong's face changed, "Who could it be?"

"The problem is in this water cooler," he analyzed. "Sister Yuerong, you must drink water from this cooler every day, right?"
"Yes." Chen Yuerong nodded.
"From now on, you shouldn't drink this water anymore, or more precisely, any mineral water in this office, as I believe someone will continue to poison it."
"Who could it be?"
"Who comes and goes from your office most frequently?"
"It's hard to say because I am the president of Jize University, so many people come to the office. If we were to investigate them one by one, it would be like looking for a needle in a haystack."
"Is there a hidden camera in this office?"
