If it were an ordinary person, they might need a while to digest and understand what Chen Xiao said.
Qin Fei, on hearing this, immediately had a sudden realization.
"The records show that Yuan Keyu's time of death was between eight o'clock at night and eleven o'clock."
"This timeframe spans three hours, but in reality, the eight to eleven o'clock period is just a rough estimate given by the forensic expert."
"With the current level of forensic analysis, the time frame can actually be extended forward and backward by small increments."
"If I recall correctly, the case files indicate that on the night of the incident, Yuan Keyu appeared in the corridor at 7:26 PM and entered the room. Prior to this, he left at 5:37 PM in the evening."
"This was the last time he left the rental flat and returned to it. Could it be possible that the person we saw last wasn't Yuan Keyu?"
Qin Fei voiced his reasoning based on Chen Xiao's hypothesis.
