"Ah, you know who killed Young Hero He?" Gu Qingyi widened her eyes.
"I know where that ginseng is," the scholar repeated.
"What difference does it make? The person who took the ginseng must be the murderer who killed Young Hero He."
"No, that's not it, the ginseng is now two hundred li away in Heyang County."

Gu Qingyi was completely baffled; even if the murderer of He Qisheng possessed exceptional qinggong, they couldn't possibly travel two hundred li in less than half an hour—unless...
"He Qisheng did not have that ginseng on him," the scholar said. "If Catcher Gu were to follow this clue, you would inevitably fail to capture the murderer."
"Who in the world are you?" Gu Qingyi asked, half-convinced, half-doubtful, "How do you know that He Qisheng didn't have the ginseng with him, and why should I believe you?"
"Who I am is not important, what matters is whom I serve," the scholar paused before continuing, "Have you heard of Jile Street, Catcher Gu?"
