Fu Xinheng could only agree, "Fine, you can't compare your running to that of other girls."
"So, a man running, panting heavily with breaths, mustn't be a long-distance runner. Running and panting are two different things. As for panting, I can definitely tell the difference. How could someone panting catch up to me? Especially since it was climbing stairs, which places an even higher demand on cardiorespiratory stamina."
"Did you mention this to the police?"
"I did hint to the police that he was panting when he caught up to me. I'm not sure if they grasped what I meant. Actually, after you, Teacher Fu, arrived, I thought about it some more and realized he might have taken some drugs that caused hyperexcitability, allowing him to catch up to me despite not being in the best physical condition."
