"Wait a minute..." After his initial shock, Zhao Yu quickly took out a pen and a piece of paper, then said, "Excuse me, I just had an operation, where I was place under general anesthesia. So, my brain isn't working well just now."
Then, he wrote something on a piece of paper and asked Jiang Ke, "When did Laogua die?"
"Hmm..." Jiang Ke thought for a moment, then said, "It was the spring before graduation, in April of 2002."
After hearing this, Zhao Yu and Cui Lizhu looked at each other before Zhao Yu said, "The Devil Case happened between August 2002 and February 2003!"
"Oh... So..." Jiang Ke thought for a moment, then said, "Han Kuan killed Laogua before the Devil Case happened. So, Han Kuan may have nothing to do with the Devil Case? Or, the person who guided Han Kuan was very clever. Maybe… When he learned that Han Kuan killed Laogua, he committed the Devil Case? Is that possible?"
