"Is it Su Nian?"
Xiong Kang furrowed his brows with uncertainty, "Logically speaking, this situation shouldn't arise. Students infected with the plague are all in the quarantine ward on the fifteenth floor, and not to mention entering the ward, people can't even get to the fifteenth floor."
A gleam flashed in his eyes.
Lu Zixun said in a deep voice, "That means, Poison Liquid is in this hospital, ready to strike at any moment."
"That's the only possibility left."
With a slight nod, Xiong Kang stroked his chin, "Su Nian must have come to the hospital earlier than us; otherwise, once the Poison Liquid releases the plague, we would definitely be able to sense it."
Now he had a rough understanding of why Su Nian was infected.
But the purpose of the Poison Liquid targeting Su Nian – whether it unintentionally found someone or deliberately targeted Su Nian – was intriguing.
Feeling that the latter was more likely, Lu Zixun took out his phone and started fiddling with it.
