Chu Tang methodically questioned all the individuals Captain Sun had implicated, only to find that none knew where the arrows ended up after being transported—they were only concerned with getting paid. Thus, the trail went cold.
Sitting in his tent, Chu Tang propped his chin with one hand, pondering any overlooked clues. Then, something came to him—he had found an arrow in the woods, possibly dropped during transport. If so, it could indicate the direction the arrows were taken.
Rising, Chu Tang went to the spot where he had found the arrow.
Looking around, he saw a river to the left, deep mountains ahead, and Liang City to the right. If they had taken the water route, there should be traces by the river. The mountains were less likely due to fewer traces, and heading through Liang City seemed improbable, as transporting so many arrows into the city would have surely alerted the authorities, including Xi Zhaoping.
